UNITED STATES int nt-ll PATENT QFFIQE,

PESSARY.

Application filed January 19, 1924. Serial No. 687,245.

This invention relates to improvements in internal uterus supports, and the objects of the invention are to relieve falling of the uterus by a devise which may be readily inserted and withdrawn without medical assistance, and it consists essentially of the device hereinafter described 'in detail inthe accompanying specification and drawings.

In the drawings;

Figure 1 is a perspective view of the device.

Figure 2 is a cross section.

The device comprises essentially a supporting member A in the form of a ball or sphere of compressible resilient material such as rubber preferablytransparent and formed with a plurality of transverse drainage passageways 10, extending in different angular directions, as shown three passageways are provided extending at right angles to each other, making six exterior openings communicating with each other.

The device is of a size to permit it to be inserted manually up the vaginal passage way until it rests on the pelvic bones and so supports the uterus, drainage being permitted through the passageways 10. As the device is compressible it may be readily inserted and withdrawn and when inserted will expand into operative position.

The passageways are of suflicient size to permit the ball to collapse considerably and they also serve as finger holds during insertion and withdrawal. The weight of the device is also reduced by these passageways. Various sizes of the device may be made to suit different patients.

As many changes could be made in the above construction, and many apparently widely different embodiments of my invention, within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all mate5 ter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

l. A, pessary comprising a compressible member of resilient material having a plurality of intersecting cylindrical passageways therethrough and inserted into the vagina, the mouths of the passageways being of small area as compared with the uninterrupted area of the outer surface or the resilient member whereby the membrane of the vagina is supported against strangulation in the passageways.

2. A pessary comprising a compressible ball of resilient material having a plurality of intersecting cylindrical passageways therethrough and inserted into the vagina whereby a hollow interior is constituted, the walls of the passageways from their mouths to the hollow interior being of suf-' ficient length to prevent the membrane of the vagina from strangulation in the hollow interior of the ball.

3. A pessary comprising a compressible ball of resilient material having a plurality of intersecting cylindrical passageways therethrough and inserted into the vagina whereby a hollow interior is constituted, the walls of the passageways from their mouths to the hollow interior being of sufficient length to prevent the membrane of the vagina from strangulation in the hollow interior of the ball, the area of the mouths of the passageways being small as compared 30 with the uninterrupted area of the surface of the ball.

In witness whereof I have hereunto set my hand.

WILLIAM GEORGE HILL.
