Z Claims.

This invention relates to an improvement in catamenial receptacles adapted to be inserted in the vagina of the human female for the purpose of receiving and entrapping the menstrual and other vaginal discharges. Catamenial receptacles of this nature are known but are not in general use because they do not effectually prevent the seepage of the menstrual discharge past the receptacle, because they are uncomfortable to wear and diflicult to insert, and because they cannot be depended upon to resume their original shape after being compressed for the purpose of insertion.

The reason for the seepage of the menstrual discharge past the former receptacles, even when of the proper shape and size, is that the surfaces of the receptacle which come in contact with the vaginal walls were of homogeneous materials with a smooth exterior which could not adapt themselves to the ridges and folds in the vaginal wall, especially during bodily movements and under the varying internal pressure exerted by the bladder and the intestines.

One object of this invention is to provide a catamenial receptacle which furnishes an effective seal against the escape of the menstrual and other discharges from the vagina.

Another object is to provide such a receptacle which may be worn with comfort and which will remain in place.

Another object is to provide such a receptacle which is easily withdrawn and inserted.

The foregoing objects and others ancillary thereto are accomplished by providing a receiving and retaining cup of relatively small proportions and surrounding its lateral sides with a layer of resilient, sponge-like material.

The novel features considered characteristic of the invention are set forth with particularity in the appended claims. The invention itself, however, both as, to its organization and method of operation, together with additional objects and advantages thereof, will be best understood from the following description of a specific embodiment when read in conjunction with the accompanying drawing, in. which:

Figure 1 is an elevationof the catamenial receptacle of this invention.

Figure 2 is a plan view of the receptacle.

Figure 3 is a sectional view of the receptacle along the line 3-3 of Figure 2.

Referring now to the drawing, I is a cup preferably made of elastic material such as soft rubber. On the rim of the cup II) is a reinforcing ridge or band I l which is of such size and resiliency that it tends to open the cup i0 against the pressure of the vaginal walls. The base of the cup carries the knob i2 by means of which the receptacle may be conveniently grasped and withdrawn from the vagina and held while cleaning the receptacle.

Surrounding the lateral side of the cup it, and

' preferably secured thereto, is a layer of soft sponge rubber l3. Sponge rubber with pores of approximately inch has given good results. The upper surface it of this layer of sponge rubber I3 is preferably inclined to form a funnel shaped surface at the top of the receptacle. To this funnel shaped surface M and to the rim I I of the cup Hi is secured a thin, imperforate covering of soft rubber 45 which covering is preferably continued for a short distance it over the outer edge of the sponge rubber it. In the drawing, the thickness of this covering I is exaggerated for the sake of clearness.

The purpose of this covering i5 is to seal the pores on the upper surface it of the sponge rubber i3 so that the discharge does not soak into the sponge rubber i3 through this surface l4 but instead will be guided down the funnel into the cup ill. The covering i5 is continued over theedge and down the lateral side of the sponge rubber It a short distance it to smoothen this edge to facilitate the insertion of the receptacle in the vagina.

To the lower surface ll of the sponge rubber l3, and attached to the base of the cup in, may be secured a second thin, imperforate covering of soft rubber Hi. The purpose of this covering I8 is to seal the pores of the sponge rubber H3 at the surface ll-to prevent the escape of any discharges and secretions which may have soaked to the bottom of the sponge rubber l3. Under ordinary circumstances, this covering is not required, asnone or at most only a small quantity seeps past the upper seal 55.

The catamenial receptacle, comprising the cup Hi; the layer of sponge rubber l3, and the rubber coverings I5 and i8, is of such resiliency and softness that it may be compressed with the fingers and inserted through the entrance of the vaginal canal with the mouth of the cup l0 towards the cervix. After insertion, the catamenial receptacle tends to return to its original shape, the rim ll opening the mouth of the cup 80 even though the sponge rubber I3 may be considerably compressed. At intervals the receptacle may be Withdrawn by means of the knob 12, emptied, cleaned, and reinserted.

The sponge rubber I3, because of the relative freedom of movement of its individual particles, effects an intimate contact with the irregular walls of the vaginal canal and establishes a seal which prevents substantially all seepage along these walls. In most cases the menstrual discharge does not seep past the outer edge l8 of the rubber covering l5. If, because of some unusual condition seepage past the edge l8 occurs, the fluid is thereafter forced to travel through the passages connecting the pores of the sponge rubber i3 and is retained in these pores, cavities. and passages. The passages connecting the pores and cavities of the sponge rubber i 3 are minute and offer a substantial resistance to the flow of the discharge so that a retardation of the seepage is effected. In the few cases where the seepage past the edge iii of the rubber covering i5 is large, the fluid will be retained by the covering IE on the lower portion of the sponge rubber i3.

The sponge rubber i3, because of its resiliency and softness, adapts itself to the shape of the vaginal canal so that the receptacle of this invention is comfortable to the wearer. By absorbing the secretions on the walls of the vagina, the particles on the surface of the sponge rubber l3 are permitted to come into intimate contact with these walls and cling to them so that the device of this invention is not displaced during violent exercise of the wearer.

This invention is to be limited neither to the shape nor the materials shown in the specific embodiment of the invention. The use of rubber, for example, is not an essential element of the invention as the cup i0 may be made of other elastic and even rigid materials and for the sponge rubber i3 may be substituted other resilient and porous materials.

A tube with a suitable closing device may be connected to the cup iii to permit periodic drainage of the cup l0 without removing the receptacle. The cup ill may also be replaced by an extended tube for continuous drainage. The invention is not to be restricted except in so far as is necessary by the prior art and the spirit of the appended claims.
