SPECIFICATION forming part of Letters Patent No. 442,558, dated December 9, 1890.

Application filed September 18, 1890. Serial No. 365,410. (No model.)

To aZZ whom it may concern.'

Be it known that I, JOHN R. TROTT, a citizen of the United States, residing at Morrisonville, in the county of Christian and State of Illinois, have invented a new and useful Vaginal Syringe, of which the following is a specification.

My invention relates to an improvementin vaginal syringes, which is adapted to be selfretaining, havin for it-s object the prevention of discomfort and fatigue; and it consists in certain features of novelty to be hereinafter described, and then particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view showing the parts assembled and the device complete. Fig. 2 is a longitudinal section thereof. Fig. 3 is -a rear view. Fig. 4 is a perspective view of the body or flaring section. Fig. 5 is a perspective view of the middle or central section with the inflated cover or sheath removed. Fig. 6 is a perspective view ot' the tip or cap.

1 represents the hollow body or daring section, which is flared similarly to a4 speculum. The inner end of the body 1 is provided with a contracted neck 2, forming at 3 an oifsetor shoulder.

4 is the central short tubular section, which at one end fits over and receives the neck 2 of the body, while its other end fits over and receives a neck 5, projecting from the hollow tip or cap 6, so as to form a shoulder or offset 7. The top of the tip or cap is provided with perforations S SL. On the inner side of the tip or cap is au eye 9, that receives hook 10 of tightening or connecting rod 11, said rod when the parts are in place passing through the tubular central section 4 and the body 1 and being screw-threaded at its outer end to receive a tightening-nut 12, that engages the outer side of a cross-strip 13, said cross-strip having a perforation 13L to receive the screwthreaded end of said rod. The cross-strip 13 bridges the narrow part of the mouth 14 of the body, its ends seating in notches or recesses 15 in the inner side of the mouth. Surrounding the tubular central section is an inflatable cylindrical rubber sheath or cover 16, which is secured snugly thereon by means of the ends of the central section and the necks and shoulders of the sections secured to it, between which the ends of the sheath are firmly held. The joints between the parts t so snugly as that they are perfectly airtight. The parts are so proportioned to each other in practice as that the sheath will be flush with the body of the syringe when out of use.

17 is an air-supply tube having an outwardly-bent end 18, that is received by an air-inlet opening 19, passing through the side of the central tubular section and communicating with the space adapted to be formed between the latter and the sheath thereon. Air under pressure may be pressed through the tube 17 by a bulb (not shown) at its outer end, as is common in syringes.

The body 1, the central section 4, and the tip or cap 6 are preferably made of hard rubber.

20 2l are a pair of rubber tubes fitted watertight in the perfor-ations 8 8, respectively, and extending through the central section and the body.

In use the syringe is inserted in the vagina, the tip end foremost, and as there are no interfering projections thereon the introduction will be free from pain. After insertion air is forced through the tube 17, so as to infiate the sheath 16, as shown in dotted lines, Fig. 2, and as said sheath occupies the inner third Yof the vaginal duct it will by reason of the enlargement formed by the inflation thereof adapt the syringe to be self-retentive within the vagina. As the sheath comes in close contact with the walls of the vagina, no fluid can escape upon the bed or clothing.

The medicine is projected through tube 20 and exhausted through waste-tube 2l. y

The advantages of my invention will be readily understood from the foregoing descrip` tion, taken in connection with the drawings hereto annexed. By the improved construction of the syringe, herein described, the inflatable sheath may be secured in position very easily and effectively, the ends of said sheath being secured between the ends of the central section and the shouldered end sections iu such a manner as to produce tight joints. The iniiatable sheath may be easily ICO replaced if broken or ruptured, and any one y of the parts of the device may be replaced at atrifling cost.

That I claim isl. In a syringe, the colnbination of a body provided with a neck and a shoulder at the base of the latter, the perforated cap or tip provided with a neck and a shoulder at the base of the neck, the central tubular section receiving said necks and having an inflatable sheath, and the connecting-rod and nut, substantially as set forth.

2. In a syringe, the combination of the body provided with a perforated cross-piece, a neck, and a shoulder at the base of the neck, the perforated cap or tip provided with a neck and a shoulder at `the base of the neck, the central tubular section receiving said necks, the inflatable sheath secured at its ends between the latter and its attached parts, the connecting-rod and nut, means for introduc` ing air into vsaid sheath, and means for conveying medicaments to the parts to be treated, substantially as set forth.

3. The combination, with the sections'of a syringe, of a cross-strip engaging one outer section, a screw-threaded rod secured to the other outer section and passing through all of the sections and said strip, an inflatable sheath mounted upon an intermediate seetion and having its ends clamped and held by the adjacent seetions,means forinfiating said sheath, means for conveying liquid to and from the parts to be treated, and a nut screwed onto the rod, substantially as and for the purpose set forth.

4E. In a syringe of the class described, the combination of a central section having an inflatable sheath, the end sections inserted into said central section and having shoulders bearing against and serving to retain said sheath, means for conveying liquid to and from the parts to be treated, and suitable connecting` means for clamping the several sections together, substantially as sct forth.

5. The combination of the central section having an inflatable sheath, the flaring end section having a cross-piece arranged across its mouth, the tip having anveye, a connecting-rod hooked in said eye and extending through the several sections, the tighteningnut whereby the sections are clamped together to retain the inflatable sheath, and means for conveying liquid to and from the parts to be treated, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature 1n presence of two witnesses.v
