SCOTT OF UHTU SANITARY STRENGTH Application filed June 30,

The present invention relates to the construction of sanitary syringes or the like, such as are usually for the treatment and medication of the vagina and adjacent organs.

The object of the invention to improve upon structures heretofore designed for the same or similar purpose and to secure more thorough and effective treatment of the or gans than with prior devices. it is an object or" the invention to provide a device of this character which may be easily inserted and expanded after insertion so as to eitectively reach all parts of the passage. it also an object to provide a device of th character in which the solution, with. which the apparatus is to be used, can be readily and safely transported without danger of leakage or loss from evaporation.

These and other objects will be accomplished and secured by the invention set forth and described herein, it being understood that while the disclosure and description are speciiic to enable those skilled in this art to understand the same, it is by no means limited to exact conformity to such details and may be modified within the scope of the in vention as set forth in the claims.

In the drawings, in which the preferred form of the invention is shown Figure 1 is a side elevation of the completed device assembled, as, for example, in carrying the same;

Figure 2 is a similar view, parts thereof being shown in section; and

Figure 3 is a sectional view with the outer casing removed as ready for use.

The device, except as stated, is preferably made from a high-grade hard rubber compound, such as is usually employed in the manufacture of medical appliances. It consists of a ring or plug 1 of rubber or metal in which is frictionally held the nozzle 2 of a syringe, the outer end of which is formed with openings or discharge ports 3. The parts 1 and 2 are held. together by the frictional contact of the inner end of the syringe with the surface of the ring, but the parts may be readily separated for cleaning and for filling. The inner end of the nozzle is 19%3. Serial No. fdii flil l.

provided with. a bead or groove to which is fitted a soit rubber bulb 5.

Elecured'in the rin 1 is an enpansible trame or core preferably consisting oi a plurality 01 out ardly extending wire spring members 6, which are preferably formed as loops and, when relieved oi any holding ttorce, expand out to a sutiicient extcn t to exp and the grind. About these spring members is secured a sponge rubber cap or swab 8 which. tits over the springs and is held in position near the ring by a clan'uging band or ring 9. This sponge rubber cap is of the ordinary material oi' this nature and is highly absorbent, the small cells or passages in the sponge rul her being'open sulliciently to permitthe pits sage of the inedicant through the sponge rubber and to permit absorption by the sponge from the surrounding parts.

In order to permit the apparatus to be tilled and carried when. not in use, a removable cap 10 is placed over the end cat the nozzle 2. For the same purpose a tubular cover 12 is placed over the bulb 5 which its the ring 1. A tubular sheath 15 is provided to cover the spring); 8 and to it over the cover 12, this sheath having a flaring mouth 16 to fit a 'nst the body. This sheath is oi such dimen. one as to readily be inserted and will hold. the spring members compressed.

0 ii. removable cap 18 is fitted over the outer end of the sheath.

When the device is to be used, the syringe and its bulb and the cap 10 are removed and the syringe is filled. The cap 10 is applied and the cover 19., sheath 15 and cap 18 are as sembied, as shown in Figure 1, the sheath compressing the spring; members and the sponge rubber cover. To use the device, he cap 18 is removed and the syringe inserted while still Within the sheath. The sheath is then removed by withdrawing over the cover 12, which causes the spring meml ers to ere panel. The cover 12 is then removed and by pressing upon the bulb, the contents oi? the bulb are forced into the sponge rubber. The sponge may then be rotated within the passage, thoroughly cleansing and niedi satin; the tissues. The device may then be remove l and separated for cleaning and re-use. The

steps set forth may be varied slightly in their order, but the advantages of the invention retained.

It Will be seen that there is provided an eX- tremely eflicient apparatus for the purposes set forth. The device is compact and effective.

What is claimed is:

1. A device for the uses and purposes set forth, comprising a syringe having a nozzle and a compressible bulb thereon, an expansibl e frame overthe nozzle, an absorbent cap over the frame, and a sheath over the cap, said sheath retaining the frame and cap compressed but removable from the nozzle after insertion of the frame.

2. A device for the uses and purposes set forth, comprisinga syringe having a nozzle and a compressible bulb, a cover over the bulb but removable therefrom, an expansible frame surrounding the nozzle, an absorbent cap over the frame, and a sheath over the cap, said sheath retaining the frame and cap in compressed condition but removable over the cover after insertion of the frame.

3. A device of the class described, comprising a syringe, a nozzle on said syringe, a porous absorbent cap over the nozzle, means to expand the cap, and a sheath over the cap to retain the same in compressed condition during insertion but removable thereafter to permit expansion of the said means.

4. A device of the class described, comprising a syringe, a nozzle on said syringe, a porous eXpa-nsible and absorbent cap over the nozzle, an expanding device Within the cap, and a sheath over the cap, said sheath being removable endwise of the syringe after insertion.

5. A device of the class described, comprising a syringe, a nozzle in said syringe, a porous expansible and absorbent cap over the nozzle, an expanding device within the cap, and a sheath over the cap, the internal diameter' of which is smaller than the cap, said sheath being removable endWise of the syringe after insertion to thereby permit the expansion of the cap.

6; In a device for the purposes set forth, a syringe, a nozzle on said syringe, an absorbent sponge-like cap over the nozzle, and a sheath over the cap, said sheath being removable BHClWlSG of the syringe after insertion.

7 In a device for the purposes set forth, a syringe, a nozzle on said syringe, an absorbent sponge-like .cap over the nozzle, a rigid sheath over the cap, said sheath being removable endWise of thesyringe after insertion, a compressible bulb on the syringe, and a cover over the bulb.

8. A device of the character set forth, comprising a syringe having a nozzle and a com pressible bulb, a frame surrounding the nozzle,an absorbent sponge on the frame,and a sheath surrounding the sponge, said sheath being removable endwise over the bulb after insertion.

9. A syringe, comprising a ring, an expansible wire frame on the ring, a nozzle seated in the ring and extending into the frame, a swab on the frame, and means to hold the frame in compressed position until after insertion.

10. A syringe, comprising a ring, an expansible Wire frame on the ring, a nozzle scat ed in the ring and extending into the frame, a porous, absorbent swab on the frame, and means to hold the frame in compressed position until after insertion, said means consistof a tubular sheatn fitting over the ring but removable therefrom.
