Another object of this inyention is to have means,fOraPai'nless and actual closing of a cavityentrince internally.

A. third object in View is a SfllfiPlG-; COH struction to lessen the efforts required to transform the nozzle to spreading device, andjto prolong-an expansion Without manual activity. I v i n AQf-urther object-of this inyention is'to provide a soft closure for the mouth of the Womb.

The utility of the compression of container 15 will be described hereinafter.

Fig. 3

container 15 is shown united with the flaring end 16 of tubular elastic stem 17 having an inwardly taperlng wall-thlckness 41 3 gradually decreasing in thickness up to a line designated by 47, and then continued as tubular nozzle 18 which shows a thinner but even wall-thickness 44. A further extension thereof is chamber 19 and the halfround nozzle-end 20. In the exterior wall of chamber 19 is a plurality of orifices as 21, and at the centerof its bottom there is a round opening 22 to which is connected tightly the narrow flexible tube 23 forming injection passage 24L and extending lengthwise through nozzle, stem and container it is fastened therein to tube union 25 which connects it to the threaded end of tube 26 which protrudes out of the container wall through threaded flange 27, which (shown partly broken away) serves as a connection to a suitable source of an injection, preferably to one which supplies an injection fluid by gravity pressure through said short tube 26 and passage 24 into distributing cham ber 19 to be discharged through the plurality of orifices 21. Said container, stem, nozzle and its end contain a fluid padding filler 30, 31, 32 and 33 which will be described hereinafter. Chamber 19 is spaced from the end of the nozzle, and asa com munication between the nozzle and its end,

there are four small tube conduits passing through and strengthening the chamber, of

which 34 is shown in section and 35 is indicated with dotted lines, and filler portion 33 reaches the nozzle-end through said conduits. Imbedded in the structure of passage tube 23 is a spirally spread outthin wire coil 48. When, after an insertion of is an enlarged detail of a syringe the nozzle, pressure is exerted on filler container' 15, as described in connection with Fig. 2, the fluid filler portion 30 will be forced into stem 17 and nozzle 18, its thin wall 14: distends to a pear-shape as indicated with dotted outline this expansion of the nozzle serves as a spreading device to open the natural folds of a cavity membrane, in a tender manner, for cleansing ormedicating purposes. wall-ed as shown, will be distended as indicated with dotted outline 16, and can be used as a soft closure of the womb, when circumstances demand that an injection there should be prevented. A further advantage of this expansion nozzle is that it can be used as a delicate internal closure for the entrance of the vagina, when the discharge of aback-flow is to be delayed to lengthen the action of a medical injection, or for sanitary technicalities; this actual closingof a cavity entrance from inside, is accomplished, after insertion, with an internally developed soft plug as indicated by outline 15, which is partially effected by the tapering wall 43 of stem 17.

Fig. 4; represents a simplified syringe of which A is the half part of an elevation shown diagrammatically, and B designates a partial longitudinal section divided by (center) line b, in which a tubular elastic nozzle has an extension as stem 51, a continuation thereof is a compressible ball as filler container 52 which is connected by its solid neck 53 to a larger injection bulb 54, shown partly broken away. In the shown upper part of injection bulb 541 opens one end of anarrow flexible tube (Stand passing through the center of neck 53, its opposite endterminates in nozzle-tip 55 and unitedtheretoit forms outlet 57 of passage 58, for the liquid contents of injection bulb 5 1. Said tip, nozzle, stem and filler container, as a whole, form an air-tight vessel which is filled with an elastic fluid filler 61,; to be described hereinafter, through a temporary small hole closed by internal stopper 63. Nozzle 50 is shown as made of a thinner wall 59 than the inwardly projecting thickness of stem wall 60, in order to feature said nozzle wall as having a greater elasticity than the stem wall. Thus it will be comprehensibleat a glance that, after insertion of the nozzle, if pressure is exerted on filler container 52, and its portion of filler 61 is forced to flow into stem andnozzle, it distends the more elastic nozzle to a bulb shape as indicated with dotted outline 62, for the purpose to be used as painless spreading device for cleansing or medicating a vaginal or rectal cavity; and, if made in reduced proportions to suit particular purposes, it can be used as an expan sion syringe for ear or nose cavities.

The hereinbefore named elastic fluid fill- Nozzle-end 20, if made thin- Hill crs which constitute the paddings shown in Fig. 3; as 30, 31, 32 and 33, andin Fig. 4 as 61, consist in these.instances, of a suitable liquid fluid, whichpistobe filled-in at: a temperature as low as thecharacter ofa suitable liquid will allow, for the plausible purpose to gain a slight expansion of the filler, and to obtain thereby an increased rigidity of'the nozzle and stem when immersed in hot water for a few minutes to heat it up to the temperature of the human body. Similar resultscan be obtained with a readily melting gelatinous substanceused as padding filler. As an alternative-modification of said padding filler, a suitable gaseous fluidis employedtherefor in a compressed and cooled state. Practically any fluid may conveniently serve as av filler-if it has not a too low boilinpoint, and is harmless tothe humanbody and to the material of the syringe.

While the accompanying drawing illus-' can be made of a hard-rubber tube because it is surrounded by an elastic padding. In-

stead of the presently shown close relation,

aetween a nozzle-stem and filler container, they can be connected by an extended flexible tube conduit, and the container compressed by stepping on it. A nozzle expansion can be stabilized to different volumes if hinge ll in Fig. 2 will be provided with several holes instead of a single eye. The cross section of the nozzles could be elliptical-or angular, instead of bein circular. The two stifi covers facilitatingpressure on a filler container would be round or oval in case the container consists of a ball or bulb.

The hereinbefore specified elastic and stiff parts of this invention are made preferably of soft-rubber, and of hard-rubber respectively, but they can be produced of one of their substitutes, or of equivalent materials.
