Briefly, the female ovulates whereupon the ovum eminates from the ovary and escapes into the fallopian tube and pro gresses to the uterus which has been preparing therefor by maturation of the endometrial lining of the uterus. Only in the event that the ovum is impregnated does it attach to the uterus wall and form into a fetus, and when not impregnated the endometrial lining of the uterus sloughs away and is discharged through the cervix into the vagina or birth canal. This discharge period or menstrual portion of the reproductive cycle produces therefore the discharge known as menses and which is composed of degenerating endometrical tissue, body fluids, and varying amounts of blood. And, although the cervix opening of the uterus into the vagina experiences changes in the premenstrual, menstrual and post-menstrual periods, the vagina retains its general configuration and can be relied upon for the retension of devices such as is disclosed herein, and namely a device for the containment and control of the menses as is normally discharged.

The vagina or birth canal is that reproductive organ which is the squamous mucus membrane canal that extends into the body from the vulva, into which the cervix of the uterus is open, and through which the menses normally flows. This organ is supported by and passes through the peroneal sling and will take a variety of positions in different individuals, but in any case is normally of tubular formation with an inner wall that has folds or the like which permit it to close together and as well to expand. The expanded diameter of the vagina is the least at the introitus near the vulva and hymen area, while it is the greatest at the upper vaginal vault or closed remote end where the cervix enters therein. Further, there is an internal border of shoulder of the pelvic peroneal sling which is superior to the introitus and which is comprised primarily of the following muscles with their facia and supporting structures; namely the pubococcygeus, levator ani, transverse parinaei and bulbo-cavernosus muscles. It is this muscular border or shoulder which forms the support upon which the device of the present invention will rest, and it is a general object of this invention to advantageously employ the aforementioned shoulder to the purpose of retaining the catamenial device in working position as shown herein.

FIELD OF INVENTION The vagina establishes a yieldingly contractible passage through which the menses is free to discharge, and the introitus and said shoulder portion is determinably measurable in practically all individuals. This muscular border or shoulder is located internal to the peroneal sling and is comfortably expansible to an approximate diameter of 1% inches (3.7 cm) in the. average individual; while the extreme expansibility is from about three-quarters of an inch (2 cm) to 2 inches (5 cm). Therefore, it is an object of this invention to provide a menses collecting device adapted to be positioned proximal to and carried by the said muscular border or shoulder within the canal of the vagina while expanding the organ comfortably inside the confines of the peroneal sling. The nominal size or diameter of this device is determined by the measured expansibility in the individual, and in practice the device is to be furnished in several nominal sizes.

The comfort and safety of the individual is of prime importance and it is to this end that the shape and construction material of this device is important. It is an object therefore, to provide a device compatible with and having substantially the same suppleness as the membrane of the in vivo organ in which it is contained. With the present invention, a thin walled device of supple and pliant plastic is provided of a material that is inert or neutral with respect to the in vivo environment in which it is useably contained.

It is another object of this invention to provide a readily insertable device of the type herein referred to, and a device that is collapsible and easily passed through the vulva and restricted introitus and smaller outlet diameter portion of the vagina. With the present invention, advantage is taken of the sizeable volume of the vaginal vault, namely the large diameter portion thereof into which the cervix of the uterus discharges. Accordingly, it is still another object of this invention to providea device that is expansible to a maximum volume and adapted to collect a substantial quantity of menses.

The catamenial device of the present invention is a chambered structure that is collapsible and which contains a compressively expansible charge of absorbent fill. The aforementioned supple walls of plastic material are formed in upper and lower hemispheres, the former being perforated and the latter being imperforate. The fill is contained therein, and the major diameter intermediate the two hemispheres is provided with seals that assure containment of fluids within the confines of the vagina. Accordingly, it is an object to provide a device having the practical features of such description, a comfortable device devoid of sharp edgesand corners, a device which will retain the menses inherently entered therein, and a device that reliably seals with the vagina walls.

lt is still another object of this invention to provide means for breaking the partial vacuum created during retraction of such a device from its sealed confinement within the vagina of an individual. Having provided an effective seal with the vagina wall, the present invention includes a valve openable to atmosphere and communicating into the innermost and largest portion of the vagina. Further, this precludes abnormal suction which otherwise might be applied to the upper vaginal vault and through the cervix and into the uterus; and all of which would hamper removal of the device.

It is also an object of this invention to eliminate direct contact between the mucus membrane and the absorbent fillmaterial that collects the menses. With the present invention the device is essentially a chambered monocoque shell with a perforated hemisphere through which the discharged menses is enterable. The absor bent fill is confined within the shell and out of contact with the mucus membrane of the vagina and cervix, while the said shell has sufficient rigidity to maintain its initially formed expanded shape with interfacial engagement with said mucus membrane walls of the vagina. Further, the expanded shape of this device is advantageously employed as a pessary in instances where support of the uterus, bladder and rectal walls is required, in which case the resiliently filled monocoque shell provides a cushioned support for these organs. The fill which is characterized by a multiplicity of resilient fibers will not dry the vaginal muscosis or adhere to the vagina walls. And, concurrent with the advantages of this structure, it is also an object of this invention to expose a lubricant as by means of removing a cap, breaking a frangible cell, or a water soluable cell.

DRAWINGS The various objects and features of this invention will be fully understood from the following detailed description of the typical preferred forms and applications thereof, throughout which description reference is made to the accompanying drawings, in which:

FIG. 1 is a sectional view taken through the central plane of the female anatomy, showing the device of the present invention installed therein.

FIG. 2 is a transverse section of the said female anatomy.

FIG. 3 is an enlarged sectional view of the device in its preferred embodiment.

FIG. 4 is a view similar to FIG. 3 showing a second embodiment of the device.

FIG. 5 is a fragmentary enlarged section showing the valve means of FIG. 3 and its operation.

FIG. 6 is an elevation showing the applicator for the device as it is stored therein. And,

FIGS. 7 and 8 are illustrative of the mode in which the device is folded for insertion into the said applicator.

PREFERRED EMBODIMENT The catamenial device herein disclosed overcomes the usual objections to other devices of the type under consideration. Realizing that the upper vaginal vault of the vagina is expansible to quite a large volume, whereas the introitus into the vagina tends to be constricted, the collapsible and subsequently expansible device herein disclosed is advantageously employed to occupy that enlarged portion of the vagina into which the menses is discharged. Unobviously, the support for carrying this device in working position is the muscular border or shoulder which occurs near the outlet portion of the vagina and said upper vault thereof, this shoulder being upwardly disposed and thereby adapted to establish support. Further, the walls of the vagina fold together and are yieldingly expansible and to the end that the mean diameter at said shoulder is flexible. Also, a factor is the introduction and intrusion of a sizeable device through the introitus and through the orifice of the peroneal sling, and all of which is enhanced by the instant device which is characterized by its curvilinear entry portion especially adapted to ease penetration into the body.

Referring now to the drawings, the body cross sections of FIGS. 1 and 2 show the installation of the expansible menses collector supported upon the upwardly disposed muscular border or shoulder which normally occurs between the introitus and upper vaginal vault. The expanded device is of rounded configuration and preferably of ovular form comprised generally of a chambered shell having a perforated upper hemisphere X, an imperforate lower hemisphere Y, an

intermediate seal Z, an absorbent fill F, lubricating means L, and a valve means V. The shell S is a monocoque structure of pliant but suitably stiff material that has sufficient memory to return to its initial shape. The two hemispheres X and Y which form the shell are permanently secured together with the absorbent fill F contained therein. The lubricating means L is a frangible or water soluable cell or peal-off element strategically located and which facilitates insertion of the device into working position. And, the valve means V is operable to release atmospheric pressure into the upper vaginal vault so as to facilitate removal of the device.

The chambered shell S is a thin walled member of pliant material and is of rounded ball form. In accordance with the invention, the ball form of the shell is elon gated on its major axis which extends coincidental with the columnar axis of the vagina, and thus the shell S is ovular and egg-shaped. As a practical matter, the shell is fabricated in halves which are joined permanently together at the major diameter mid-cross section of the member. The wall of the shell is a self-supporting monocoque structure of pliant and supple material which is collapsible and yet sufficiently stiff and resilient in order to return to its initial formation, or to the general configuration of the individual vaginal vault in which it is contained. A suitable material is rubber or a plastic substitute therefor which is deformably pliable and adapted to return to these configurations after prolonged collapse. Further, the physical properties of such material closely resemble the soft nature of the vagina wall, but necessarily the material of the shell S is substantially harder than the said body tissues, and all to the end that the normal constrictive forces applied by the vagina through the full range of body movements will not collapse the device when in use. However, it is to be understood that there is ,a suitable flexibility in the device which permits it to deform in configuration and in conformity to the changes in shape which take place in the vagina during the various expected body movements, and to the individual differences in vaginal configurations.

The upper hemisphere X of the chambered shell S is a tapered curvilinear dome and is perforated as shown for the reception of the menses discharged into the vagina. The channeling of discharge from the cervix is at random and to this end the entire upper surface of the shell S and upper hemisphere X is perforated and/or of screen form, thereby permitting entry of fluids into the chambered interior of the shell.

The lower hemisphere Y of the chambered shell S is semi-spherical and imperforate for the retension of the menses discharge collected therein from the upper hemisphere X. The hemisphere Y is essentially, therefore, a vessel or basin which contains the discharged fluids that collect therein.

The intermediate seal Z that engages the vagina wall prevents discharge of the menses to the body exterior and is a wing-like structure that projects radially from the peripheral major diameter of the shell S and is preferably in the form of a plurality of encompassing ribs 10 that extend outwardly and upwardly to circumferentially continuous lips 11 respectively. These ribs 10 are of relatively thin cross section and are thereby membranous and of flexible nature, being integrally formed of the aforementioned plastic material and adapted to conform to all irregularities substantially without leakage. As shown, the multiple lips are spaced and together establish a labyrinth which supplements and en hances the seal.

The absorbent fill F that is contained within the chambered shell can vary widely. For example, it can be a cellular sponge or it can be a collection of spaced fibers. In either case, the fill F is a collapsible body that is resilient and adapted to expand into full occupancy within the chamber shell S when said shell expands into full form. In practice, resilient fibers are employed and into which the discharged body of fluids are readily absorbed. It is to be understood that the density of said fibers is established by the particular physical properties thereof and their ability to retain the said body fluids therebetween.

The valve means V that is operable to release atmospheric pressure into the upper vaginal vault is a normally closed valve which is releasable as and when required in order to facilitate removal of the device from working position. As is shown, the shell S of the device is expanded and rests upon the aforementioned muscular border orshoulder formed by the peroneal sling. Furthermore, the intermediate seal Z effectively isolates the innermost vaginal vault from the introitus thereof which opens to atmosphere. Thus, when extraction force or movement is applied there would be a consequent suction or partial vacuum applied within the said innermost vault and which opens through the cervix and into :the uterus that communicates to the fallopian tubes and lower abdomen. Application of such a negative pressurization could be discomforting or injurious, and as well cause mechanical difficulty in removal of the device.

Accordingly, therefore, an extracting means E is provided in the form of a lanyard that depends from the lower hemisphere Y of the shell and said lanyard is tubular for transmission of fluid (air) therethrough. In its preferred form, valve means V is normally closed and releasable to open at the top of the upper hemisphere X, and therefore it extends through the chamber within the shell S. As shown in FIGS. 1-3- and 5, the lanyard 20 is a depending loop that fairs tangentially into the opposite inner walls of the lower hemisphere Y; and the valve element V is a plug or button 26 at its lowermost extremity and which is ripped off manually when required. As shown in FIGS. 4, 6 and 8, the-valve element is a stem 21 that depends axially from the interior side of the upper hemisphere X and slideably (slip-fit) engages in the otherwise open end of the lanyard 20, forming a plug. The lanyard 20 projects axially through the lower hemisphere Y where it frictionally (press-fit) engages in an opening therethrough. Astop 22 projects laterally from the lanyard normally spaced above the interior side of the lower hemisphere Y and said stop engages said interior side when the upper terminal end of the lanyard is pulled free of the valve stem 21. In practice, a finger loop 23 is provided at the lower end of the lanyard and which is engageable (also the loop 25) to apply downward force and movement for both seating of and extraction of the device from the vagina. As is clearly indicated, the lowermost terminal end of the tubular lanyard is open to atmosphere. Like the shell of the device, the tubular lanyard 20 (and 25) is made of soft pliable material so as to be conveniently trained into a conveniently obscure position during use.

An applicating means A is provided in the form of an open ended cylinder through which a piston 31 is manually operable to press the collapsed shell S therefrom. Such applicators are common and a description thereof is quite unnecessary, however the disposition and configuration of the shell S is quite unique and cooperatively combined with the cylinder 30 for its practical application and insertion into a working position. In other words, the collapse, initial projection and subsequent expansion of the shell S is practical and readily accomplished by virtue of foldability of the supple shell and its fill as will now be described: Firstly, the ovular shell S of egg-shape is collapsedlaterally (see FIG. 7) so as to fold in a substantially vertical plane with one side half thereof bilaterally depressed into the other side half thereof. Secondly, the bilaterally collapsed shell S is rolled circumferentially (see FIG. 8) so as to minimize its cross section. And thirdly, the folded and rolled shell S is slideably entered into and stored within the confines of the open ended tubular cylinder 30 as shown in FIG. 6 with its tapered curvilinear foremost end exposed for ease of penetration. The aforesaid collapse results in the compression of the fill F of resilient fibers which subsequently expand to open the shell S toward its initially formed monocoque shape. Reversely therefore, the shell walls then unfold under the expansive influence of the resilient fill from which the confining pressure has been released, and thereafter the shell S seeks its full pre-form as shown installed in FIGS. 1 and 2 herein.

The lubricating means L that facilitates insertion of the device is a peel-off element, or frangible or water soluable cell-that exposes or releases a lubricant as and when so required. As shown, the orientation of shell 8 is on its major longitudinal axis of insertion coincidental with the columnar axis of the vagina. Therefore, the tapered and curvilinear upper hemisphere X is foremost and initiates entry into and through the vulva; and in accordance with this invention the lubricating means L is located strategically over theforward apex (when folded) or curvature of said upper hemisphere. As shown, the peel-off element or frangible and/or soluable cell is in the form of a cap 50 carried over the otherwise open end of cylinder 30 to protectively cover the tapered curvilinear end portion of the device which exposedly projects therefrom. In practice, the protective peel-off element can be removed in its entirety and said frangibility thereof can be enhanced and/or controlled by forming the cell walls of a water soluable material that is substantially weakened when placed into contact with water or body fluids. The lubricant to be exposed can vary as circumstances require and for example can be a form of petroleum jelly, water soluable jelly, or the like.
