Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The terms used in the present specification are terms selected in consideration of the functions and effects in the embodiments, and the meaning of the terms may vary depending on the intention of the user or the operator or industry custom. Therefore, the meaning of the term used in the following embodiments is based on the defined definition when specifically stated in this specification, and unless otherwise stated, it should be interpreted in a sense generally recognized by those skilled in the art.

FIG. 1 is a block diagram illustrating an integrated perfusion device according to an embodiment of the present invention. Referring to FIG. And FIG. 2 is a block diagram showing a medical device for an integral-type blood-backflow prevention valve according to an embodiment of the present invention. The integrated medical blood supply check valve 200 of FIG. 2 may have a structure in which one end of the integrated flow control device 100 of FIG. 1 is integrally coupled to the blood return check valve 210. Therefore, the embodiment of the present invention will be described in detail with reference to FIG. 1 and FIG.

Referring to FIGS. 1 and 2, the integrated blood return valve medical device 200 includes a blood backflow prevention valve 210 and an integral flow regulation device 100. The integrated perfusion device 100 includes a three-way branching device 110, a drug infusion conduit 120, and an extension line 130. Each of the branch lumens 111, 112 and 113 of the three-way branching device 110 and the blood backflow prevention valve 210, the medicine inflow pipe 120 and the extension tube 130 are connected to each other through the connection portions A, B, C, respectively.

The blood backflow prevention valve 210 prevents the blood flow backward out of the body through the lumen of the conduit in the blood vessel. The structure of the blood backflow prevention valve 210 may be the same as the structure of the whole blood backflow prevention valve known in the art. According to the present embodiment, the side lumen 214 of the non-return valve 210 is connected to one of the branch lumens 111, 112 and 113 of the three-way branching device 110, And may be formed integrally with the branch lumen 111. [ The inner surface of the connection portion A between the side conduit 214 and the first branch lumen 111 may have a step-free shape, which will be described later.

The anti-reflux valve 210 includes a guiding unit 212 configured to insert a medical device, such as a conduit, a guide wire, and / or a catheter, along a longitudinal centerline. The medical instrument such as a catheter may be inserted into the one end 212a of the guide 212. [ For example, the one end portion 212a may be a structure in which a hose or the like is coupled to the outer peripheral surface. A thread may be formed on the inner circumferential surface and / or the outer circumferential surface of the other end portion 212b of the guide portion 212, which is merely an example. The hemostatic valve 210 may be formed of a thermoplastic elastomer (TPE) such as polyisoprene or silicone rubber.

A side conduit 214 may be formed at a predetermined position between both ends 212a and 212b of the guide 212 to form a predetermined angle with the guide 212. And may be integrally connected to the first branch lumen 111 of the three-way branching device through the side conduit 214 such that predetermined medicines necessary for treatment, inspection, and / or treatment are input. The medicine or the like is injected through the medicine inflow pipe 120 and is guided through the second branch lumen 112 and the first branch lumen 111 of the 3-way branching device 110, 0.0 > 212 < / RTI >

The three-way branching device 110 is structured such that three hoses having a predetermined length, that is, first to third branch lumens 111, 112, and 113, face three different directions. One ends of each of the first to third branch lumens 111, 112, and 113 are integrally connected to each other. At the center where the first to third branch lumens 111, 112, 113 meet, a split valve 114 is located. The divider valve 114 can selectively limit the path of the medicament such as the contrast agent supplied from the second branch lumen 112 and / or the third branch lumen 113 and the pathway of the sap containing heparin . The restriction method may be performed in such a manner that only one branch lumen of the second branch lumen 112 or the third branch lumen 113 is opened through the split valve 114. [ Depending on the embodiment, the split valve 114 may be configured such that both the second branch lumen 112 and the third branch lumen 113 may be simultaneously opened by the split valve 114.

The other end of each of the first to third branch lumens 111, 112, and 113 of the three-way branching device 110, that is, the opposite end connected to the split valve 114, is configured to face in different directions. And each of the opposite ends thereof is integrally formed with other components. More specifically, the first branch lumen 111, which is one of the three branch lumens 111, 112 and 113 constituting the three-way branching device 110, is connected to the side conduit 214 And the connection part A may be integrally connected to each other. The second branch lumen 112 of the three-way branching device 110 may be integrally connected to the drug inflow pipe 120 and the connection portion B, The base lumen (113) may be integrally connected to the extension tube (130) and the connection portion (C).

As such, each of the first to third branch lumens 111, 112, 113 of the three-way branching device 110 is connected to the side conduit 214 of the other catheter, that is, the blood backflow prevention valve 210, 120, and the ends of the extension tube 130 and the connecting portions A, B, C, respectively. According to the present embodiment, there is no particular method for connecting the two conduits or tubes. Preferably, the connecting portions A, B, and C may be connected to each other such that conduits connected to the connecting portions A, B, and C do not interfere with the flow of medicines or liquids passing therethrough.

FIGS. 3A and 3B are views showing an example of a method of connecting two conduits in at least one connection portion of the connection portions A, B, and C, respectively, according to an embodiment of the present invention.

Referring to FIG. 3A, the first and second conduits 12 and 14 connected to each other at the connection portion may have a structure in which their inner diameters are at least equal to each other. Thus, when the inner diameters are matched, there is no step between the two conduits 12 and 14 at the connection portion, so that the flow of the fluid (drug or liquid) flowing therethrough can smoothly flow without being disturbed. The first and second conduits 12, 14 are arranged to face each other and the connecting method can be connected to the outside of the connecting part by using a predetermined joining member 16. As such, the joining member 16 disposed on the outside may not disturb the flow of the fluid at all.

Referring to FIG. 3B, the diameter of the second conduit 14 may be larger than the diameter of the first conduit 12 connected at the connection. The first conduit 12 is the fluid outflow direction and corresponds to the fluid inflow direction of the second conduit 14. And the joining member 16 may be disposed between the outer surface of the first conduit 12 and the inner surface of the second conduit 14 to bond the two tubes 12 and 14 and to maintain the hermeticity. Thus, if the diameter of the first conduit 12 is less than the diameter 14 of the second conduit, a high pressure acts on the conduit in the outflow direction and the fluid can be supplied smoothly.

The first branch base lumen 111 corresponds to the main lumen of the integrated perfusion regulator 100. The first branch base lumen 111 may comprise a conduit of a predetermined length and shape. For example, the first branch lumen 111 has a linear shape of a predetermined length (about 2 cm) from the first connection portion A, a gentle curved shape thereafter, and then a predetermined length About 3 cm). The reason why the first branch base lumen 111 forms a curved shape in the middle is that the portion of the split valve 114 is positioned right, up, down, left, and right. The first to third branch lumens 111, 112, and 113 can maintain 90 degrees at the center of the split valve 114 so that the split valve 114 is properly positioned.

The diameter of the first branch base lumen 111 may be about 1 mm to about 2 mm. The first branch base lumen 111 is preferably made of a material having hardness and flexibility that does not break even when moving up and down and left and right. In addition, when the first branch lumen 111 moves up and down and right and left, it is preferable that the blood return check valve is made of a material having flexibility so as not to move. And the inside of the first branch lumen 111 is formed of a material capable of withstanding a pressure of 1000 psi or more. If the interior of the first lumen lumen 111 does not meet this requirement, the injection of the contrast agent (which is currently used at a rate of about 300 to 800 psi at about 5 cc or more per second when using the contrast injection machine) The base lumen 111 may absorb all of the pressure to slow the injection rate of the contrast agent, or the first branch lumen 111 may rupture. In addition, the first branch lumen 111 can be formed of a transparent material, which makes it possible to observe how air bubbles enter through the first branch lumen 111.

The second branch base lumen 112 corresponds to the connection lumen (tube) of the drug infusion conduit 120 of the integrated perfusion regulator 100. That is, the second branch lumen 112 is integrally connected to the medicine inflow pipe 120 through the connection portion B. The structure of the connecting portion B may be the same as that shown in Fig. The second branch base lumen 112 may also be configured as a conduit of a predetermined length and shape and may have a shorter and more straight shape than the first branch lumen 111. The diameter of the second branch base lumen 112 may also be about 1 mm to about 2 mm. And the interior of the second branch lumen 112 is preferably formed of a material capable of withstanding a pressure of 1000 psi or greater.

The third branch lumen 113 corresponds to the connecting lumen (tube) of the extension tube 130 of the integrated perfusion regulator 100. That is, the third branch lumen 113 may be integrally connected to the extension tube 130 through the connection C. The structure of the connecting portion C may be the same as that shown in Fig. The third branch base lumen 113 may also be a conduit of a predetermined length and shape and may have a shorter and more straight shape than the first branch lumen 111. The diameter of the third branch base lumen 113 may be about 1 mm to about 2 mm, but it may be the same as the diameter of the extension tube 130 for supply of the liquid or the like. The inside of the third branch base lumen 113 can withstand a predetermined pressure, but the requirements of the first and second branch lumens 111 and 112 are not strict. This is because the supply pressure of the liquid or the like is not large. Also, it is preferable that the third branch lumen 113 is formed of a transparent material so that air bubbles can be observed inside the tube.

The medicine inflow pipe 120 can receive a predetermined medicine from the outside through one end (direction opposite to the connection portion B). One end of the medicament inlet pipe 120 may be directly connected to the contrast injection device and the medicament inlet pipe 120 may be connected to the injection port of the three- The second contrast lumen 112 and the delivered contrast agent is introduced into the side conduit 214 of the non-return valve 200 through the split valve 114, the first branch lumen 111, and the connection A, . As shown in the drawing, the medicine inflow pipe 120 is disposed in the rightward direction around the three-way branching device 110 so that one end of the medicine inflow pipe 120 can be easily connected to the contrast injection device And may have a shape that curves to protrude.

The diameter of the drug inflow tube 120, or the inner diameter thereof, may be about 1 to 2 mm, which is the same as the diameter (inner diameter) of the second branch lumen 112. And the length of the drug inflow pipe 120 may be about 8 to 20 cm, but is not limited thereto. The drug inflow pipe 120 is also preferably made of a transparent material in order to observe the existence of air bubbles in the inside of the tube. The inside of the drug inflow pipe 120 is also preferably formed of a material capable of withstanding a pressure of 1000 psi or more. If the inside of the medicinal inflow pipe 120 does not satisfy this condition, the medicinal inflow pipe 120 (at the time of injecting the contrast medium, at present, about 5 cc or more per second is used at about 300 to 800 psi) ) May be completely absorbed to slow the injection rate of the contrast agent, or the drug inflow tube 120 may be ruptured.

The extension line 130 has a hose shape having a predetermined length and may be integrally formed with the third branch lumen 113 of the three-way branching device 110 through a connection C . The extension tube 130 is a component for extending the third branch lumen 113 of the three-way branching device 110 to more effectively receive a predetermined fluid (liquid) from the outside. For example, one end of the extension tube 130 (the opposite end connected to the three-way branching device 110) may be connected to the ringer bottle and the end portion may have a pore shape for this purpose.

The liquid solution supplied through the extension tube 130 may be supplied to the body and / or perform functions such as cleaning of conduits and the like. Thus, the extension tube 130 may have the same diameter as a common liquid line. And the length can be more than about 2m. The hardness of the extension tube 130 may be lower than other conduits and may be formed of a transparent material to observe whether air bubbles enter the interior. (Liquid containing heparin) supplied through the extension tube 130 is transferred to the split valve 114 through the connection portion C and the third branch lumen 113 and is also transferred to the first branch lumen 111 ), The connecting portion (A), and the side conduit (214).

For example, the anti-reflux valve 210 is a medical device widely used in the related art, and various types of anti-reflux valves 210 may exist. For example, it is preferable that the side conduit 214 of the anti-reflux valve 210 is formed at an angle fixed to the guide hole 212, as well as the angle depending on the surrounding condition such as the patient's physical condition or the movement of the patient Adjustable shapes are also possible. It is also possible to add a sealing member to the guide hole 212 of the blood backflow prevention valve 210 to prevent inflow of outside air. That is, the present invention is not limited to the above-described type of the blood backflow prevention valve 210, but may be applied to various types of blood backflow prevention valves capable of performing a similar role, So that the integral blood backflow prevention valve medical device 200 can be constructed.

In the integrated perfusion device 100 according to the above-described embodiment, the second branch lumen 112 and the medicine inflow pipe 120 are connected to each other without a step through the connection part B to form an integral structure, It is assumed that the lumen 113 and the extension tube 130 are connected to each other through a connection C without a step to form an integral structure. However, this is merely illustrative, and not the structure in which the second branch lumen 112 and the drug inflow conduit 120 are connected via the connection portion B, but the whole is a single conduit structure (in this case, And the third branch lumen 113 and the extension tube 130 are not connected to each other through the connecting portion C but may have a single conduit structure (in this case, the connecting portion C is not provided) ). In this case, the integral type flow control device 100 includes the first branch lumen 111, the second main branch branch lumens 112, 120, B, and the third main branch branch lumen 111, (113, 130, C) may be connected.

Also, depending on the embodiment, the blood backflow prevention valve 210 may be integrally formed in the integrated flow regulating device 100. In this case, the integral anti-reflux valve medical device 200 is configured such that the side conduit 214 of the anti-reflux valve 210 is connected to the first branch lumen 111 of the integral perfusion device 100, . ≪ / RTI >

As described above, the integrated perfusion device 100 according to the present invention and / or the integrated type blood-flow-backflow prevention valve medical device 200 including the integrated perfusion-type device 100 have an integral structure as a whole. In this case, it takes no time to assemble each component constituting the integrated perfusion device 100, for example, the medicine supply tube 120 and / or the extension tube 130 into the three-way connection part 110. According to this, if it takes time to connect the members in a medical environment where an emergency can occur at any time, it can have a great influence on the treatment of the patient. When the blood backflow prevention valve 210, the three-way branching device 110, the medicine supply pipe 120, and the extension tube 130 are assembled and used for the emergency operation, air bubbles not removed during the assembly process There is a possibility that air flowing into the blood vessel through the conduit or air existing in the joint portions A, B, and C flows into the blood vessel through the conduit during the procedure.
