UNITED STATES ADOLF EARTH, OF MUNICH. GERMANY.

SYRINGE.

Application filed January 15, 1926, Serial No. 81,477, and in Germany November 11, 192 4.

My invention relates to syringes and more especially to a uterine syringe of the kind in which the liquid supply tube is arranged within a discharge tube adapted to fill the entire vagina.

Devices of this kind as hitherto designed and which also serve for rinsing the vagina, ailord the possibility of injecting liquid. into the uterus, but a washing out of. disease bearers and the like which may be present in the uterus, cannot be effected.

In the syringe according to the present invention this is obtained owing to the fact that not only the part filling the vagina but also the part projecting into the uterus is provided with a discharge tube. This latter discharge tube has a smaller diameter than the tube filling the vagina, and the air in the uterus together with the rinsing liquid can therefor pass through the narrower discharge tube into the wider discharge tube inserted in the vagina.

In the drawings afiixed to this specification and forming part thereof a syringe embodying my inventionis illustrated diagrammatically by way of example. In the drawings Fig. 1 is an axial section of the discharge tubes, showing the supply tubes in elevation.

Fig. 2 is an axial section of the supply tubes and the fillings mounted thereon.

Fig. 8 is a cross-section of the larger supply tube, and

Fig. 4 is a cross-section on the line A-B in Fig. 1. a

Referring to the drawings, 1 is the curved main supply tube, 2 is a sleeve mounted on the free end of this tube and 1 is the narrower supply tube which is designed to be introduced in the uterus. On the free end of tube 1 is mounted a hollow syringe head 1 ending in a hemispherical projection. 4 are perforations adjoining the projection. 6 is the main discharge tube designed to fill out the vagina and 6 is a cover closing same and serving for mounting the smaller discharge or drain tube 5 surrounding the smaller supply tube 1. The drain tube 5 has a number of perforations, which also occur in the wall of the main discharge tube 6, which is closed at its bottom end by a cast piece 7 having an extension 7 fitted into tube 6 by grinding and an outlet branch 7'. In the cast piece 7 the supply tube 1 is mounted for axial displacement. WVhen the tube 1 is thus displaced in the discharge 6, the end of the smaller supply tube 1 will be drawn further into the drain tube 1 until the hemispherical projection abuts against the free edge of the drain tube 1 whereby the rinsing liquid supplied through tubes 1 and l is prevented from further escaping through the perforations .4 The amount of displacement is regulated by means of a collar 8 mounted on the bottom end of the main supply tube 1.

The operation of this device is easily understood :the rinsing liquid entering through tubes 1 and 1 escapes through the perforations at and after having rinsed the interior of the uterus passes through the perforations 5 into the drain tube 5 and the main discast piece 7 can now be removed and all the parts can easily be cleaned.

I Wish it to be understood that I do not desire to be limited to the. exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

I claim;

1. Uterine syringe comprising liquid supplying means adapted to be introduced through the vagina into the uterus, a main discharge tube surrounding part of said supplying means, a separate drain tube of smaller diameter than said main discharge tube surrounding the end portion of said supplying means designed to be introduced in the uterus, a valve at the end of said end portion adapted to be closed by said drain tube, when said supplying means are displaced in axial direction and means for limiting such displacement.

2. Uterine syringe comprising liquid supplying means adapted to be introduced through the vagina into the uterus, a main discharge tube surrounding part of said supplying means, a Y separate drain tube of J smaller diameter than said main discharge tube surrounding the end portion of said supplying means designed to be introduced in the uterus and a perforated syringe head at the end of said supplying means, said head being arranged to be closed by said drain 10 tube, When said supplying means are displaced in axial direction.

In testimony whereof I affix my signature.

ADOLF BARTH.
