Description

Receiving device for a medical device

The invention relates to a receiving device for receiving a medical device, in particular a Blutprobenentnahrneröhrchens a blood collection device comprising a receptacle with a closed end by a closure device, the receiving device comprises a receptacle with a container shell, the distanced from each other in the direction of a longitudinal axis of a distal and forms the proximal end, an at least partially disposed in the region of the distal end end wall, wherein the container shell and the end wall define a receiving chamber and the receiving chamber in the direction perpendicular to the longitudinal axis defines a clear cross-section, formed by the container shell holding device for the inserted into the receiving chamber medical device, a needle assembly to be fastened to the receptacle, one end of which, after being placed on the receptacle, is inserted in the receptacle he protrudes.

From EP 029 126 Al a blood collection device with a hollow cylindrical holder has become known, in one end of a double-ended hollow needle used and in the other and open end formed a blood sample tube is inserted. For orientation of the needle tip of the needle is further provided that the needle is arranged in an adjusting ring which is rotatable in an opening in the holder. Further provided in the holder in the relaxed state, the insertion and withdrawal of the blood collection tube non-obstructing tongue that is so far elastically bend inwardly into the interior of the holder by an operator that it engages behind the screw cap and this secures against falling out. The tongue is formed by a slot in the holder. The operation of the retaining tongue was difficult and incorrect operations were not excluded in all cases.

Another blood sampling device has become known from EP 0 562 363 A1, which comprises a receiving device with a holder for a blood sample tube, an adapter part inserted in the holder and a double-ended sample withdrawal needle. One end of the sampling needle protrudes into the interior of the holder and when inserting the blood sample tube, this can be pierced by the end of the sampling needle. For taking a blood sample, the blood sample tube is for insertion into the receiving provided during insertion, the end of the extraction needle covering elastic sheath in the axial direction is compressed until the end of the needle pierces both the shell and the stopper of Blutproberöhr- Chen. An adapter part is arranged between the holder and the evacuated blood sample tube. This adapter part has a cylindrical body with an outer dimension that is smaller than an inner dimension of the receiving device. At this cylindrical body a plurality of flexible extensions is formed, which are connected at one end to the cylindrically shaped body and projecting therefrom. These extensions extend axially of the cylindrical body so that they surround the plug of the inserted blood sample tube. The individual extensions are directed forwardly and have an inclined portion which is inclined from the uppermost end of the cylindrical body, starting from the axial center of the cylindrical body in the direction of the upper end of the holder. Following the flexible extensions, a front gripping portion is still provided, which extends parallel to the axial center of the cylindrical body from the oblique portion. Furthermore, additional retaining elements may be provided in the transition region between the flexible extensions and the front gripping portion. However, sufficient retention of the blood sample tube could not be achieved in all applications.

Another connector for a vessel for the introduction or withdrawal of a vaccine culture has become known from EP 0 587 347 B1, DE 693 06 070 T2, US 5,344,417 A and US 5,374,264 A. This connector has a main portion with a means for receiving a needle and an annular edge. This edge extends from the main portion and serves for positioning over the liquid inlet portion of the vessel. On the annular edge, a plurality of ribs are further disposed on an inner surface thereof projecting radially inward. These ribs are capable of engaging the inlet portion of the vessel to substantially center and securely hold the fitting on the vessel during introduction or withdrawal of the vaccine culture. It could not be achieved in all applications, a secure hold of the fitting on the intended for removal or introduction vessel.

Other adapters with retaining projections are known from EP 0 192 661 B, the No. 4,607,671 A ₅ of EP 0 363 770 A1 and EP 0 351 643 A2. The disadvantage of this is that when placing or removing the adapter piece from the respective vessel, the entire outer circumference of the adapter piece must be correspondingly deformed in all these adapter pieces, the holder was achieved by a circumferential, annular collar or individual on the inner surface protruding nubs.

The present invention has for its object to provide a receiving device for receiving a medical device having a holding device, which is inexpensive to manufacture and easy to use and safe to use.

The object of the invention is achieved in that the holding device comprises at least one an inner surface of the container casing in the direction of the longitudinal axis superior holding element and the holding element is designed such that this protruding from a clear cross-section of the receiving chamber and thereby with the medical Device engaging detent position is formed in a releasing the medical device release position by an aligned in the direction of the longitudinal axis relative adjustment between the medical device to be used and the container shell is automatically adjustable. The resulting by the features of the characterizing part of claim 1 surprising advantage is that at least one holding element of the holding device in its rest position protrudes into the clear cross section of the receiving chamber and upon insertion of the medical device in the receiving chamber without additional operation from the outside an automatic adjustment of the holding element is performed. Thus, on the one hand, the insertion or insertion of the medical device into the receiving chamber allows and on the other hand secured after reaching the predeterminable position, the medical device accordingly against falling out. This prevents inadvertent pushing out of the medical device from the receiving chamber by the deformed, sleeve-shaped sheath and thus ensures a reliable removal process. After acceptance or filling of the blood sample tube, this can be easily pulled out of the receiving chamber without any further additional actuation. A further advantage is that a one-piece receiving device has thus been created, which can be produced cost-effectively without additional assembly costs, save for the possible insertion of the removal needle in an injection molding process. Due to the relative deformability - A -

the holding device, in particular of the holding element, with respect to the container shell this remains during the insertion process and the retention process of the medical device in its cross-sectional shape to almost undeformed or unchanged. The deformation movement takes place exclusively by the holding device itself.

Also advantageous is a further embodiment according to claim 2, as this can be easily taken into account different heights and configurations of the closure devices of the blood sample tube.

A further advantage is an embodiment according to claim 3, as a still more secure hold between the medical device and the receiving device during normal use can be achieved.

Due to the design according to claim 4, it is possible to find without Auslangen without additional cost of materials while achieving a secure retainer.

According to another embodiment variant according to claim 5 or 6, the insertion movement of the medical device in the predetermined position, namely the detent position, much easier, since this can be done without significantly increasing the insertion force. As a result, the risk of additional puncture injuries of the patient is avoided, as would otherwise be possible with otherwise jerky adjustment movements.

Also advantageous is a development according to claim 7 or 8, characterized in that a sufficient locking force between the retaining element and the medical device can be achieved in dependence on the force applied by the hull-shaped shell back pressure force.

Due to the design according to claim 9, it is possible to accommodate medical devices with different outer dimensions with one and the same receiving device and still achieve sufficient rest or restraint forces.

Through the development according to claim 10 it is achieved that achieved on the outer surface of the support arm a planar surface and beyond the formation of the injection mold is simplified. In the embodiment according to claim 11, it is advantageous that as a result the contact area between the holding element and the medical device to be used can be kept relatively low and nevertheless a sufficient retention of the medical device in the receiving device is ensured.

By virtue of the embodiment according to claim 12, a jerky withdrawal of the medical device held in the receiving device can be prevented.

Through the development according to claim 13 ensures that characterized in continuous arrangement of the connecting part over the entire circumference of the receiving device, a closed receiving chamber can be created. Nevertheless, an elastic adjustment of the retaining element relative to the container wall is still possible.

Also advantageous is an embodiment according to claim 14, since thereby the insertion movement or the recording of the medical device in the receiving device is facilitated and still in the holding or operating position, a sufficient retention force can be achieved.

Due to the design according to claim 15 or 16, the elastic spring behavior and the associated retention forces can be easily adjusted to different operation operations.

Through the development according to claim 17 it is achieved that the holding device on the one hand has a continuous course, which can be found with smaller wall thicknesses with constant restraining forces Auslangen.

In the embodiment according to claim 18, it is advantageous that lever arms are thus created for the deformation of the holding device, which on the one hand facilitate the insertion movement and on the other hand ensure stable retention of the medical device within the receiving device.

Due to the construction according to claim 19, the deformation characteristic and on the other hand, the restraining forces for the male in the receiving device medical Device can be easily adapted to a variety of conditions.

Also advantageous is an embodiment according to claim 20, as this not only the springback force and thus the associated locking action between the holding member and the medical device easily adapted to different operation operations, but also the reliability can be significantly increased.

Through the development according to claim 21 it is achieved that thereby a sufficiently intrinsically rigid container casing can be produced. Thus, lower deformation forces or associated retention forces of the holding device can be achieved, thereby preventing jamming of the medical device in the receiving device.

The embodiment according to claim 22, it is possible to prevent unwanted locking by the user of the holding device, since the engagement surface is arranged on the support arm recessed relative to the outer surface to this. Because the entire holding device is chosen to be relatively small in area relative to the outer surface of the receiving device, contact with the recessed surface of the carrying arm and the associated holding element with a finger or thumb of the user is not easily possible or completely prevented.

Through the development according to claim 23 ensures that characterized in continuous arrangement of the connecting part over the entire circumference of the receiving device, a closed receiving chamber can be created. Nevertheless, an elastic adjustment of the support arm relative to the container wall is still possible.

Due to the embodiments according to claims 24 or 25, the suspension behavior of the holding element can be adapted to a wide variety of medical devices and thus facilitates the operation of the user in a simple manner.

Also advantageous is an embodiment according to claim 26, characterized in that a resilient arm is provided, which is integrally connected to the container shell and still a secure support in connection with the holding element for the medical device can be created. As a result, when inserting the medical device not only one unintentional loosening of the cap prevents the tube, but this also pushed even more on this.

But are also advantageous embodiments according to claim 27 or 28, as a resilient component has been created, which is aligned opposite to the insertion direction of the medical device, whereby upon withdrawal prevents unintentional engagement behind and a possible possible removal or opening of the medical device becomes.

Also advantageous is an embodiment according to claim 29, characterized in that the open passage cross-section in the region of the slot can be kept relatively low, whereby an unwanted escape of liquids or tissue parts to be received in the medical device is virtually prevented in this area. Furthermore, the inherent rigidity of the support arm is increased by the relatively short design of the legs of the slot, which in the end with lower wall thicknesses Auslangen can be found.

Also advantageous is an embodiment according to claim 30 or 31, as this despite the release of the holding element or support arm with unhindered freedom of movement, the container wall can be almost completely formed.

According to an embodiment as described in claim 32, a simple shaping of the holding device is achieved. In addition, the spring behavior of the retaining element with the associated support arm is not adversely affected or stiffened.

In this case, embodiments according to claim 33 or 34 prove advantageous because a safer and, above all, more uniform retention of the medical device in the receiving device is achieved.

In accordance with claim 35, an additional centering of the medical device during its insertion into the receiving device is at least partially achieved between the holding devices in their immediate vicinity. As a result, a centric puncture of the cannula is ensured by the closure device. In addition, however, a safer locking of the holding elements is achieved with the medical device. It is also possible to have an embodiment according to claim 36, as this results in no jamming or incorrect insertion of the cannula into the sealing device over the entire insertion length of the medical device into the receiving device.

The embodiment according to claim 37 is advantageous, since only in certain areas a guide is created between the medical device and the receptacle during the insertion movement into the receptacle. If the displacements of the guide surface are aligned parallel to the longitudinal axis, here a simple longitudinal guide can be achieved during the entire intended use, whereby the reliability is substantially increased.

Finally, however, an embodiment as described in claim 38 is possible, as this already sufficient pre-centering of the medical device with the closure device relative to the held in the receiving device cannula can be done. As a result, an almost centric puncture is achieved by the closure device, in particular the sealing element.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained throughout the description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the position information selected in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to a new position analogous to the new situation. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

FIGS. 1 to 6 show a possible embodiment of a receiving device 1 for receiving a medical device 2, in particular a blood sampling tube 3 of a blood sampling device. The medical device 2 can furthermore also be used for receiving body fluids, tissue parts or tissue cultures and in turn comprises a simplified receptacle 4 and at least one closure device 5, with which at least one end region of the receptacle 4 is closed.

The receiving device 1 in turn comprises a receptacle 6 with a container casing 7, which distanced from each other in the direction of a longitudinal axis 8, a distal end 9 and a proximal end 10 forms. Here, the distal end 9 is to be understood as referring to the patient to whom the receiving device 1 is turned during the intended use.

Furthermore, the receptacle 6 comprises an end wall 11 arranged at least in regions in the region of the distal end 9. The container casing 7 and the end wall 11 define a receiving chamber 12. The proximal end 10 of the receptacle 6 is designed to be open in this embodiment and the medical device 2 , starting from the proximal end 10 towards the distal end 9, are pushed into the receiving chamber 12. The receiving chamber 12 is preferably formed in its cross-section circular with respect to the longitudinal axis 8 and can, starting from the open proximal end 10 towards the distal end 9 at least in the region of its outer Ren surface 13 be conically tapered, as is usually carried out in injection molded plastic parts. Furthermore, the receiving chamber 12 defines a clear cross section 14 in a plane aligned perpendicular to the longitudinal axis 8 or in a direction perpendicular thereto. This clear cross section 14 is to be formed as a function of the medical device 2 to be accommodated in the receiving chamber 11.

Furthermore, the receiving device 1 also comprises a needle assembly 15 to be fastened to the receiving container 6, which needle arrangement is formed by a double-ended cannula 16 in the present exemplary embodiment. The cannula 16 is further associated with a needle-holding part 17, with which the needle assembly 15 can be coupled in the region of the end wall 11. Regardless of this, it would also be possible to directly mold the cannula 16 into the receptacle 6 during the manufacture of the receptacle 6 with it in one operation or to glue the cannula in the region of the end wall 11.

One end of the needle assembly protrudes after the arrangement of the receptacle 6, starting from the end wall 11 into the receiving chamber 12 into it. To protect against the escape of remaining within the cannula 16 remaining amounts of liquids that part of the cannula 16, which projects into the receiving chamber 12, in a known manner a hull-shaped protective cover 18 made of an elastically deformable, pierceable, and self-closing material assigned.

In order to establish a flow connection between the cannula 16 and an interior 19 of the receptacle 4, it is necessary to insert the medical device 2 into the receiving chamber 12 of the receptacle 6 until the end of the cannula 16 projecting into the receptacle chamber 12 is elastically displaced deformable sealing element 20 of the closure device 5 passes through, so as to produce the flow connection subsequently. In this case, the sleeve-shaped protective sleeve 18 is also pierced and pushed along the cannula 16 together. Due to the material of the sleeve-shaped protective sheath 18 inherent, elastic and spring-back properties, it may happen that the medical device 2 is adjusted by the prestressed, hull-shaped protective sleeve 18 so far out of the receiving chamber 12 in the direction of the open proximal end 10, so that the flow connection between the cannula 16 and the interior 19 is interrupted. This unwanted relative movement between the Recording device 1 and the inserted medical device 2 can also be supported by a the sliding properties of the cannula 16 improving and thus reducing the friction coating. This coating serves to facilitate the puncture process by the sealing element 20 of the medical device 2. This can occur if the user of the receiving device 1 does not carry out a mutual positional fixation between the receiving container 6 and the medical device 2 when the inner space 19 is in fluid communication with the cannula 16.

In order to avoid an unwanted pushing out of the medical device 2 from the receiving chamber 12, the receiving device 1 is further associated with a holding device 21, which is formed by a part of the container shell 7. The holding device 21 in turn comprises at least one, an inner surface 22 of the container shell 7 in the direction of the longitudinal axis 8 superior support member 23. The holding member 23 is formed such that this protruding from a clear cross-section 14 of the receiving chamber 12 and thereby with the medical Device 2 engaging detent position in a release of the medical device 2 release position is designed to be automatically adjustable. This adjustment or displacement between the two positions takes place by means of a relative adjustment movement in the direction of the longitudinal axis 8 between the medical device 2 to be used and the container jacket 7 in the radial direction with respect to the longitudinal axis 8. The holding element 23 projecting into the clear cross section 14 becomes Area of the holding member 23 a comparison with the clear cross-section 14 lesser cross-section or clearance defined and so the medical device 2 relative to the receptacle 6 in its inserted into the receiving chamber 12 position held or fixed until a conscious unlocking and connected a release of the medical device 2 from the receptacle 6 takes place.

In addition to the sealing element 20, the closure device 5 can also have a cap 24 comprising it. The cap 24 has in a known manner a cap jacket 25, which forms a cap edge 26 on the side facing the receptacle 4 side.

The holding element 23 is arranged so far away from the end wall 11 of the receptacle 6 that the holding element 23, the cap edge 26 of the inserted into the receiving chamber 12 medical device 2 on the open proximal end 10 of Receptacle 6 facing side behind. This ensures that, on the one hand, the sealing element 20 is completely pierced by the cannula 16 protruding into the receiving chamber 12 and, on the other hand, the entire medical device 2 can not be inadvertently pushed out of the receiving chamber 12 against the direction of insertion by the sleeve-shaped protective sheath 18.

In order to favor the holding element 23 of the holding device 21 in its relative movement relative to the stationary container casing 7, it is advantageous if this is associated with at least one support arm 27 or the holding element 23 is connected to this and preferably integrally formed. This support arm 27 may extend from the distal end 9, ie from the region of the end wall 11, toward the proximal and open end 10 of the receptacle 6, wherein the support arm 27 is connected to the container casing 7. The support arm 27 is in turn part of the container shell 7 as well as the holding element 23. To determine the suspension properties of the support arm 27, this has a wall thickness 28 which corresponds to a maximum wall thickness 29 of the container shell 7. Preferably, however, the wall thickness 28 of the support arm 27 is selected to be smaller, in order not to increase too strong with sufficient retention force of the support members 23 for the medical device 2 for the user of the Aufnalimeeinrichtung 1 separating force. As a result, a jerky extension of the medical device 2 from the receiving device 1 is avoided, and nevertheless a secure retention is achieved in the held position of the medical device 2 within the receiving device 1.

To facilitate this Ausschwenkbewegung for release of the medical device 2, it is advantageous if the holding member 23 and / or the support arm 27 is at least partially connected via a foil-like, elastic connecting member 30 with the container shell 7 or are. For this purpose, between the holding element 23 and / or the support arm 27 and the container jacket 7 at least partially a slot 31 with these limiting slot walls 32, 33 arranged or formed. This slot 31 can fully penetrate the container jacket 7 or its container wall, but also the additional connection member 30 described above may be provided or arranged in this slot 31, as schematically simplified from a synopsis of FIGS. 4 and 6 can be seen is. The connecting part 30 is indicated in Fig. 6 in dash-dotted lines. With the arrangement of this connecting part 30, it is possible, on the one hand, to have a reaching radial adjustment of the retaining element 23 with respect to the largest cross section 14 of the receptacle 6 to allow and on the other hand still form a completely enclosed receiving chamber 12, provided that the connecting part 30 is arranged continuously in the slot 31 or formed. The necessary radial adjusting forces for the relative displacement of the holding element or elements 23 and optionally of the carrier arm or arms 27 relative to the container jacket 7 depend on the wall thickness of the film-like, elastic connecting part 30. However, this connecting part 30 could also be formed in the course of a multi-component injection molding from a material different from the material of the receiving container 6. This material then has a high elongation at low stress and thus a lower modulus of elasticity than the container shell 7. As a result, the connecting part 30 is made more elastic in its properties.

Due to the combined arrangement of the holding element 23 with the support arm 27, the slot 31 seen in the vertical direction on the longitudinal axis 8, an approximately U-shaped and preferably continuous longitudinal profile. Legs 34 of the U-shaped extending or aligned slot 31 extend from the holding element 23 in the direction of the closed distal end 9 or the end wall 11. In addition, the legs 34 of the U-shaped slot 31 in the vertical direction on the Seen longitudinal axis 8 have a widening longitudinal profile, whereby the distance between the legs 34, starting from the holding element 23 towards the junction of the support arm 27 with the container wall 7, increases. The slot has a width between the slot walls of between 0.3 mm and 2.0 mm, preferably between 0.8 mm and 1.2 mm. This not only a technically simpler shape for the injection molding process is possible, but also prevents mutual jamming between the adjustable components and the fixed container wall.

If the elastic springback force of the above-described connecting part 30 is too great for the necessary release force of the medical device, then only a portion of a film-like cover element 35 can be arranged in the slot 31, as best seen in FIG. 6 in the right-hand part is. In this case, the cover member 35 with only one of the slot 31 delimiting slot wall 32, 33 is connected. In the present embodiment, the cover member 35 is connected to the slot wall 32 and disposed thereon, which is formed by the container shell 7. It extends the film-like cover member 35 preferably only partially between the spaced-apart slot walls 32, 33 in order to form this form-technically more favorable. Thus, the film-like cover member 35 extends, starting from the container casing 7 in the direction of the holding device 23 and the support arm 27. However, it would also be possible independently to arrange the film-like cover member 35 on the holding device 23 and / or on the support arm 27 , so that this extends in the direction of the container casing 7. Regardless of this, however, a cover element 35 could also be arranged on each of the two slot walls 32, 33, which then extends in the direction of the respective opposite slot wall 32, 33 and preferably ends before it. With appropriate design and arrangement, the two cover 35 may overlap in the slot 31, whereby on the one hand a simple adjustment of the holding device 23 and / or the support arm 27 and on the other hand, a nearly completely closed receiving chamber 12 can be achieved.

As can now best be seen from FIG. 6, the retaining element 23 also has a wall thickness 36 which corresponds at most to the wall thickness 29 of the container jacket 7. Preferably, however, the wall thickness 36 by about 5 to 20%, but usually also 30 and 45% smaller than that of the remaining container wall 7 is selected. For example, the wall thickness 29 of the container wall 7 in the region of the open proximal end can be approximately 0.8 mm. The wall thickness 28 of the support arm 27 and the wall thickness 33 of the support member 23 may be about 0.5 mm.

The holding element 23 is seen in cross-section - see Fig. 6 - formed in an approximately L-shaped and has converging legs on. This shape is therefore chosen to save plastic material in this area and to achieve an approximately continuous same wall thickness 28 and 36 respectively.

Thus, the holding element 23 on the side facing the proximal end 10 on a guide surface 37, which tapers, starting mostly from the inner surface 22 and from the proximal end 10 towards the distal end 9. As a result, the insertion of the medical device 2 into the receiving chamber 12 results in mutual contact and deformation of the support arm 27 connected to the holding element 23. The guide surface 37 forms an angle 38 with the longitudinal axis 8 which lies in a range with a lower limit of 10 °, preferably 20 °, in particular 30 ° and an upper limit of 35 °, preferably 45 °, in particular 50 °. This guiding surface 37, which generally runs relatively flat with respect to the longitudinal axis 8, thus facilitates the insertion of the medical device 2 into the receiving chamber 12 with simultaneous puncturing of the sealing element 20 of the closure device 5.

Furthermore, the retaining element 23 has on the side facing the distal end 9 a holding surface 39 which, starting from the distal end 9, is designed to taper in the direction of the proximal end 10. The holding surface 39 in turn encloses with the longitudinal axis 8 an angle 40 which is in a range with a lower limit of 40 °, preferably 50 °, in particular 55 ° and an upper limit of 65 °, preferably 70 °, in particular of 75 °, lies. This substantially steeper angle to the longitudinal axis 8 selected angle 40 forms on the one hand with its holding surface 39 sufficient support and on the other hand, the medical device 2 in turn can pull out of the receiving chamber 12, without causing the closure device 5, in particular their cap 24, and optionally the sealing element 20 is withdrawn from the blood sampling tube 3.

Furthermore, it is advantageous if a transition region between the holding surface 39 and the guide surface 37 is formed starting from the holding surface 39 almost sharp-edged or only with a slight rounding, so as to achieve an additional latching or holding action. Because the receiving device 1 is basically a disposable article, it is disposed of after a single use even with multiple, consecutively taking place decrease of blood below.

Preferably, the holding device 21 a plurality of, the inner surface 22 of the container shell 7 superior support members 23. In the present embodiment, two diametrically opposite to the longitudinal axis 8 opposite holding elements 23 are provided.

As can best be seen from FIG. 4, the connecting piece or the transition region between the support arm 27 and the container jacket 7 faces the distal end 9 or is assigned to the latter in its next region. The holding element 23 is spaced as a function of the insertion of the cannula 16 in the sealing element 20 approximately at the end of the front third, starting from the distal end 9 toward the proximal end 10 arranged. In order to achieve alignment of the medical device 2 to be used with respect to the longitudinal axis 8 and the holding element or elements 23 for the puncturing operation and the holding process to take place later, it is advantageous if the inner surface 22 of the container skirt 7 facing the longitudinal axis 8 at least in the region of the holding device 21 partially formed a guide device 41 with an at least region-wise trained guide surface 42 for the inserted into the receiving chamber 12 medical device 2. This guide device 41 preferably interacts with the end area of the medical device 2 that is closed by the closure device 5. In this case, for example, the guide surface 42 of the container casing 7 may be cylindrical, resulting in a slight thickening of the wall thickness 29 in this area relative to the remaining container casing 7. As a result, since this receiving device 1 is an injection-molded part, it is designed for easier demolding with the usual draft angles, which are, for example, in a range of 0.5 to 3 °. Furthermore, the guide surface 42 projects beyond the holding element 23 in the direction of the open proximal end 10.

The guide surface 42 of the guide device 41 could, however, independently of this, as shown schematically simplified in FIG. 7, be formed by an offset 43 of the container jacket 7 directed in the direction of the longitudinal axis 8. This offset 43 only forms a deformation of the container jacket 7, whereby the arrangement of additional ribs on the inner surface 22 and, associated therewith, an excessive accumulation of material is avoided.

With a corresponding mutual arrangement or dislocation - in the present case of 90 ° - with respect to the respective opposing holding elements 23 and guide surfaces 42, there is always a secure access of the holding element 23 with the medical device 2 to be received therein. A lateral sliding during the insertion movement the medical device 2 in the receiving chamber 12 is thereby prevented. The longitudinal extension of the displacements 42 in the direction of the longitudinal axis 8 is again to be chosen so that even before the insertion process of the cannula 16 in the sealing element 20 is already a guide the medical device 2 relative to the receptacle 6. The dislocations 43 of the container jacket 7 described above can be used, for example, if the basic outer shape of the receiving container 6 of the receiving device 1 is to be retained, but the receiving chamber 12 is to accommodate different sized medical devices 2 in its cross section. This can be done by appropriately trained inserts in the forming tool a simple conversion, without the need for a completely new mold must be made.

FIGS. 8 to 11 show a further possible and optionally separate embodiment of the receiving device 1 with at least one retaining device 21 formed thereon, wherein the same reference numerals or component designations again apply to the same parts as in the preceding FIGS 7, to be used. In order to avoid unnecessary repetition, reference is made to the detailed description, in the preceding Figs. 1 to 7, respectively.

This receiving device 1 in turn comprises the receptacle 6 with the container casing 7, the distance from each other in the direction of the longitudinal axis 8 forms a distal end 9 and a proximal end 10. The container shell 7 and the end wall 11 define the receiving chamber 12. The proximal end 10 of the receptacle 6 is also formed open in this embodiment and is used for insertion of the medical Device 2 in the receiving chamber 12. The container casing 7 has on the side facing away from the receiving chamber 12 side, the outer surface 13, as well as on the receiving chamber 12 side facing the inner surface 22.

In the region of the distal end 9, the receiving chamber 12 again has the guide device 41 with at least one guide surface 42 for the relative mutual positional positioning of the medical device 2 to be inserted into the receiving chamber 12. This in turn results in a mutual alignment between the medical device 2, in particular its sealing element 20, and the cannula 16 penetrating it.

To be used in the receiving chamber 12 and during normal use to be held medical device 2 from accidental ejection or to prevent it from falling out of the receiving cam 12, here again the holding device 21 is provided, which is structurally different from the previously shown exemplary embodiment.

The holding device 21 shown here in turn comprises the holding element 23, which is arranged on the support arm 27 in the present exemplary embodiment. The support arm 27 is designed to be shorter in contrast to the previously described exemplary embodiment in its extending in the direction of the longitudinal axis 8 length. The support arm 27 with the protruding in the direction of the longitudinal axis 8 holding member 23 is formed in the region of its outer periphery on three sides of the U-shaped slot 31 separated from the rest of the container wall 7. The connection with the container jacket 7 takes place on the side facing away from the holding member 23 and the distal end 9 facing portion of the support arm 27. The U-shaped extending slot 31 in turn has the two legs 34, which towards the distal end. 9 , starting from the holding element 23, extend. The longitudinal course of the legs 34 can in turn be seen in the vertical direction on the longitudinal axis 8, have a widening longitudinal course. In this embodiment shown here corresponds to a length 44 of the leg 34 of the U-shaped slot 31 in approximately a longitudinal extent 45 of the holding member 23 seen in the circumferential direction, and in a direction perpendicular to the longitudinal axis 8 aligned plane.

Between the slit walls bounding the slot 32, 33, the film-like cover member 35 may again be arranged at least in some areas, which is here connected to the slit wall 32 delimiting the slot 31, in particular formed thereon. This cover element 35 serves to further minimize the access cross section from the outer surface 13 to the receiving chamber 12 in the region of the slot 31.

The support arm 27 has a wall thickness 28 with respect to the wall thickness 29 of the container jacket to 28 small wall thickness. Thus, a formed on the support arm 27 on the side facing away from the receiving chamber 12 side outer surface 46 with respect to the outer surface 13 of the container shell 7 can be arranged offset to this in the direction of the receiving chamber 12. This has the advantage that, due to the areally relatively small design of the holding device 21 with respect to the surface 13 when the receiving device 1 is touched or held by the operator, there is no unintentional displacement or adjustment of the holding device. direction 21 takes place. Likewise, however, an overhanging of the outer surface 13 is prevented or minimized even during the snap-in or release operation of the medical device 2 by the receiving device I in the course of the common adjustment movement of the support arm 27 with the holding element 23 arranged thereon.

As can best be seen from FIG. 10, in this exemplary embodiment, too, the holding element 23 again has the guide surface 37 facing the proximal end 10 and the holding surface 39 facing the distal end 9. With respect to the longitudinal axis 8, the guide surface 37 or holding surface 39 in turn close the previously described in detail angles 38, 40, which are within the limits specified therein. Preferably, the angle 38, for example, a size of 46 ° and the angle 40 of 70 °.

In contrast to the embodiments previously described in FIGS. 1 to 7, here, the holding member 23 is formed as a solid body, whereby the support arm 27 may be formed in the region of its outer surface 46 planar over. Furthermore, in FIG. 10, it is further indicated in simplified form that a transition radius 47 is formed in the transition region between the holding surface 39 and the guide surface 37. This transition radius 47 can be kept relatively low and, for example, be 0.3 mm.

The receiving device 1 with its clear cross section 14 is designed such that a recording of different dimensions having medical devices 2 is possible. Currently, blood sampling tubes 3 having a nominal dimension of 13 mm and 16 mm, respectively, are commonly used. Due to these different dimensions of the receptacle 4, the respective closure devices 5 also have mutually different outer dimensions in the plane aligned perpendicular to the longitudinal axis 8. In order not to have to provide different receiving devices 1 for the different medical devices 2, the guide device 41 is formed in the receiving device 1 such that it ensures sufficient guidance and positioning for both nominal dimensions.

When dimensioning the closure devices 5, in particular the caps 24, it was attempted with the different nominal dimensions of the medical devices 2, the respective outer dimensions of the closure devices 5 with each other to develop only small dimensional differences.

The retaining forces of the holding device 21 for fixing the medical device 2 relative to the receiving device 1 can be effected by varying component dimensions. The restraining forces can be defined by determining a so-called withdrawal force, which is necessary to release the medical device 2 fixed by the holding device 21 in the receiving device 1. The size or the extent of the restraining force or the pull-out force to be applied by a user can be a lower limit of 1 N, preferably 2 N, up to an upper limit of 5 N, preferably IO N, wherein this is also the case Dimension of the medical device 2 is dependent. For example, if a medical device having a nominal size of 13 mm is used, the retention force may be 2N. For the same receiving device 1, but a medical device 2 with a nominal dimension of 16 mm, the retention force or the withdrawal force can be 5.5 N.

The retention or extraction forces described above can be set and determined by varying the length or longitudinal extent of the support arm 27 and / or the wall thickness 28 of the support arm 27 and / or the formation of the support member 23 itself. If the support arm 27 and the leg or legs 34 connected thereto are relatively short and the wall thickness 28 is chosen to be relatively high, the retention or extraction forces are increased by the higher deformation resistance. The same also applies to the choice of the angle 40 of the support surface 39 with respect to the longitudinal axis 8. The steeper the support surface 39 is inclined to the longitudinal axis 8, the higher the retention or extraction force. Furthermore, the restraining or the pull-out forces can also be influenced by the projection or the projection of the holding elements 23 into the clear cross-section 14 of the receiving chamber 12.

FIGS. 12 to 16 show a further possible and optionally independent embodiment of the receiving device 1 with at least one holding device 21 formed thereon, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 11 become. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 11 or reference. This receiving device 1 in turn comprises the receptacle 6 with the container casing 7, which in the direction of the longitudinal axis 8 has the distanced distal end 9 and the proximal end 10. Furthermore, the receptacle 6 comprises an end wall 11 arranged at least in regions in the region of the distal end 9. The container casing 7 and the end wall 11 surround the receiving chamber 12. The proximal end 10 of the receptacle is designed to be open in this exemplary embodiment and serves to insert the medical device 2 into the receiving chamber 12. The container casing 7 has on the side facing away from the receiving chamber 12 side, the outer surface 13 and on the side facing the Aufhalimekammer 12 the inner surface 22.

In the receiving chamber 12, in the region of the distal end 9, in turn, the guide device 41 can be arranged with at least one guide surface 42 for the relative mutual positional positioning of the medical device 2 to be inserted into the receiving chamber 12. Thus, in turn, a mutual alignment between the medical device 2, in particular its sealing element 20, and the cannula 16 penetrating this can be achieved.

The holding device 21 shown here in turn comprises the holding element 23, which is connected via the support arm 27 in the region of the distal end 9 with the container jacket 7 in a connecting region 44 with this, in particular molded thereto. Starting from the holding element 23, the holding surface 39 also extends toward the distal end 9. In contrast to the exemplary embodiments shown and described above includes the holding surface 39 with the longitudinal axis 8 a much flatter angle 40, which is in an area with a lower limit of 1 °, preferably 2 °, in particular of 3 ° and an upper limit of 10 °, preferably of 15 °, in particular of 30 °. By means of this rather flat angle 40, a longer retention section is provided for the medical device 2 to be retained therein. As a result, even larger differences in dimensions of the medical device 2 can be compensated and still a secure retention in the receiving device 1 can be achieved.

The support member 23 is assigned to the proximal end 10 side facing another support arm 45 and is connected thereto. The further support arm 45 is likewise connected to the container jacket 7 in a further connection region 46. Prefers is the support arm 27 and optionally the further support arm 45 angularly with respect to the container shell 7, starting out respectively from the two connecting portions 47, 46 towards the longitudinal axis 8 and the receiving chamber 12 projecting aligned, as best seen in the axial section of FIG 15 and 16 can be seen.

The holding element 23 further has, on the side facing the proximal end 10, the inclined guide surface 37 which, starting from the smallest cross section with respect to the longitudinal axis 8 of the holding element 23, widens in the direction of the inner surface 22 of the container jacket 7. The holding member 23 with its guide surface 37 passes here on a planar surface in the further support arm 45, which in turn connected to the container casing 7, in particular formed thereon, is.

The two support arms 27 and 45 and the holding member 23 with its guide surface 37 and holding surface 39 forms an approximately strip-shaped elongated component, in which case a connection with the container casing 7 takes place only in the two connecting regions 44, 46. By directed in the direction of the longitudinal axis 8, ie on the inside of the receptacle 6 holding device 21 and the strip-like formation in the same longitudinal extent, only a connection to the container shell 7 in the portion of the two connecting portion 44, 46. Seen over the longitudinal extent forms the holding device 21 an elastically deformable component of the container jacket 7, wherein in the longitudinal extension of the entire holding device 21 between the two connecting portions 44, 46 of the slot 31 formed on both sides of the strip-shaped elongated member or is arranged. This slot 31 forms the exemption of the holding device 21 relative to the container casing 7, but is part of the same. The container shell 7 forms in the region of the slot 31 on the side facing the holding device 21 from the previously previously described slot wall 32, which here preferably extends parallel to the holding device 21 and is arranged on both sides thereof.

The entire holding device 21 with its holding element 23 and the support arms 27, 45 arranged thereon preferably has the same wall thickness 28 over its longitudinal extent, which is chosen to be smaller with respect to the wall thickness 29 of the container jacket 7. Based on the wall thickness 29 of the container jacket 7, the wall thickness 28 of the holding device 21 can be between 20% and 50%, preferably between 30% and 40%, preferably 35%, be chosen lower. Thus, the deformability and restraining force can be adjusted.

Due to the mutually angular alignment of the holding element 23 with the guide surface 37 facing the proximal end 10 and the adjoining holding surface 39 extending in the direction of the distal end 9, the entire holding device 21 is moved over the longitudinal course thereof during the insertion movement of the medical device 2 to be held therein , in particular deformed in the angularly aligned transition areas. The deformation takes place on the side facing away from the longitudinal axis 8 side. After insertion of the medical device 2 in the intended position 2, a spring-back of the entire holding device 21 takes place in the direction of the longitudinal axis 8, whereby a sufficient retention force is built up. Due to the shallower inclination of the holding surface 39 in contrast to the previously described embodiments, larger dimensional differences of the medical device 2 to be held therein can be compensated or absorbed.

As can further be seen best from FIG. 13, the holding device 21, in particular the holding surface 39 of the holding element 23, has a concave spatial shape or surface with respect to the longitudinal axis 8 in a plane oriented perpendicular thereto. The holding surface 39 additionally extends in the direction between the two ends 9, 10 of the receptacle 6. This concave configuration of the holding surface 39 may also extend into the region of the guide surface 37. Preferably, the two support arms 27, 45, this concave configuration with respect to the longitudinal axis 8 and the perpendicular to the cross-sectional plane.
