To all 'whom it may concern.

Be it known that I,- LESLIE R. SAUN- Dnns, a citizen of the United States, residing at Los Angeles, California, have invented a new and useful Syringe with Electric Attachments, of which the following is a s ification.

bjects of this invention are to provide a syringe of the character stated in which the body portion and nozzle ofI the syringe are so formed that they will not injure the organs, and are combined with means for strengthening the syrin e so that it will not be bent out of shape or roken by handling.

Another object is to provide in combination with the syringe proper, means to conduct an electric current into the fluid injected into the vaginal cavity and cause, the

Among the benefits obtained by passin an 'electric current through a body of liqui confined to the vaginal cavity are the following When the negative pole of the circuit is in contact with the liquid it tends to produce an astringent action on the surface of the membrane. When a medicated solution is added to the liquid and the positive pole connected therewith cataphoresis is produced which adds greatly to the eii'ectiveness of the medicated solution. Also certain abnormal organic conditions of the secret-ions may be corrected by the electrochemical action of the current.

It is a well known fact that the electric current is a deroyer of disease germs. For this reason the apparatus herein described is of great value in the treatment of infectious diseases.

The syringe is adapted for treatment of rectal and intestinal diseases of both sexes. Referring to the accompanying drawin which illustrate the invention embodied 1n a preferred orm,-Figure 1 is a longitudi- Specioation ot Letters latent.

nalmid-section of the syringe proper. Fig. 2 is a bottom view thereof. Fig. 3 is a vertical section on line m-a: of Fig. 1, showing 1n addition a portion of the electrical apparatus connected therewith. Fig. 4 is a side elevation of the syringe showing the electrlcal apparatus connected therewith. -Fig 5 is an enlarged fragmental detail of the device which carries the indiderent electrode.

Referring in detail to the drawing,-the bell-shaped body 1,'preferably made of hard rubber, is rovided with an expanded flanged portion 2 adapted to seal the entrance to the vaginal cavity, an elongated inwardly projecting nose or nozzle la and a shank or handle 3 within the anged portion of the body and projecting outwardly therefrom. Said handle 3 is of unequal dimensions in cross section being desirably approximately elliptical in cross-section. Through the upper portion of said handle extends, longitudinally thereof, the straightinlet conduit or metal tube 5, said tube extending completely through the handle and nearly to the discharge end of the syringe. Said tube forms a suitable support upon which the rubber body of the syringe is molded.

In the treatment of female diseases it is often necessary to use water heated to a temperature that will more or less soften the hard rubber of which it is desirable to construct the syringe. For this reason the metal tube 5 performs an important function by preventing the syringe from being bent or twisted out of shape. The rubber body of the syringe is molded over said tube 5 in the process of manufacture so that said tube is securely embedded in said body forming an integral part thereof throughout the entire portion of the tube within said body. Said inlet tube 5, being incased in the rubber body of the syringe, will not allow the electric current to pass directly into the body of the patient but only through the liquid. At the discharge end of the syringe, the bore into which the tube 5 fits is contracted to form the discharge passage 6 which terminates in the intersecting cross grooves 7 and 8 which distribute the stream laterally cleansing the parts more ei'ectually. Ordinarily whenA the syringe is in operative position the fluid will discharge from the reduced channel t3 in an unbroken stream from the tip of the rammed .time 25, 1era.-

nozzle with considerably increased velocity on account of the cross-sectional opening of the passage 6 being a reduction 1n size of the passage through the inlet tube 5. If, however, an obstruction be encountered opposite the end of the tip of the syringe the intersecting grooves 7 and 8 will provide an escape for the fluid, thus preventing the inflow of the stream from being checked by such obstruction. The sudden reduction of the cross-sectional area of the discharge end of the inlet channel causes the fluid to be discharged with greatly increased force. In case the tip of the syringe meets any obstruction, the grooves 7 and 8 afford lateral outlets for the fluid.

The lower portion of the handle and body is provided with the longitudinal ougtlet passage 11 consisting of a circular bore which opens out at its inner end obliquely to the surface of the lower side of the body of the syringe at an angle of less than fortyive degrees with respect to the surface thereof which surrounds the mouth ot said bore, thereby forming in effect at a single operation a tapering groove on the lower side of the body as best shown in Fig. 2. Said passage 11 is provided at its outer end with an enlarged threaded. portion 12 into which the tube 13 screws.

The recess .2a within the flanged portion of the body of the syringe and around the base of the handle 3 enables the operator to take a longer, firmer holdupon said handle.

The body of the syringe is constructed of hard rubber which will take a smooth finish, and there are no mechanical diiculties to its insertion. The curves of the surfaces are so arranged that it will automatically adapt itself to both large and small openings.

This syringe is an improvement upon others of its class in respect to the symmetrical contour of the hard rubber body and nozzle of the syringe. The syringe 1s molded with curves which conform to the anatomical curve of the vagina, bringing the tip of the syringe into proper relation to the uterus to cleanse the parts most etliciently.

In order to provide for adjusting the position of the indifferent electrode 21 the spring arm 22 is provided with a longitudinal slot 23 near the free end thereof. The screw 24 enters the back of pad 25 and grips the end of arm 22 thus holding the pad 25 adjustably in place and at the same time making good contact for wire 26. Arm 22 is provided with an attaching loop 22 which tits over stem 3 being kept from rotation by the unequal cross-sectional dimensions o said stem to maintain the pad 25 carried by said arm in proper position with relation to the tip of the syringe.

5a designates the supply tube which is desirably the flexible rubber tube of a water bag or other elevated source of fluid supply l outwardly therefrom, an

(not shown). 13a is the discharge tube which is fastened'to the lower tubular member 13 and has a bore of the same size as passage 11. These tubes are both shown in Fig. 4.

31 is a spring clipy from which leads the Wire 32 to the battery 33. Said clip 3l is provided with arms having out-bent curves 31 which spring over the tube 5 to make good contact therewith.

35 is a pinch-cock to control the escape of fluid through the drainage tube 13a. In treating rectal diseases, the outlet or drainage duct will not be used, but will simply be closed by its pinch-cock, and the indierent electrode 21 may be detached and applied to whatever portion of the body desired.

The battery 33 may be any one of a variety of medical batteries in general use, but is desirably a light, portable battery.

I claim:

1. In a vaginal syringe, a body of insulating material, said body being provided with a nozzle, an internal reinforcing member united to and forming an internalreinforcement for both said body and nozzle, said reinforcing member being of conductin ma-` terial and projecting from the end o said body opposite said nozzle, there being an extension of insulating material which projects from said body and surrounds the pro jecting portion of said reinforcing member, an electrode adapted to engage the body of the patient, and means for supporting said electrode, said supporting lmeans being mounted upon said extension -and thereby insulated from said reinforcing member.
