12 Claims. `l The present invention relates to a novel construction of pessaries of the uterine type, adapted Afor use in medical treatment, such as in the treatment of pathological conditions.

One of the objects of the present invention is to provide an improved device of the character indicated, which readily conforms to the contour o the vaginal canal and which, due to its form and construction resiliently retains itself in proper position.

Another object is to provide an improved device of the character indicated, which is of resilient form for maintaining proper contact with the walls of the vaginal canal and which readily accommodates flexions of the body of the user without exertion of deleterious pressure on the delicate tissues of the canal.

A further object is to provide an improved device of the character indicated, having a body of resilient material surrounding a yieldable reinforcing member andwherein portions of the reinforcing member are free to move within the body of yieldable material so as to reduce frictional movement of corresponding portions of the body of resilient material over the tissues of the Vaginal canal incident to flexions of the body of the user.

A still further object is to provide an improved device of the character indicated, provided with a stem having one or more relatively thin flexible disks connected to and surrounding the stem and each having a peripheral notch whereby said disks, when the device is positioned for use in the cavity of the uterus and its cervix, causes the disks to assume a substantially frusto-conical form for assisting in retaining the device in proper position and also serving to prevent the entrance of foreign substances into the cavity of the uterus while permitting normal flow of the discharges from the uterus.

A still further object is to provide animproved pessary of the character indicated which is of relatively simplified form, durable and practical in use, capable of being easily cleansed and which may be economically manufactured.

With these and other objects in view, my invention consists inthe details of construction and arrangement of parts of the device, ,and the details of procedure involved in the practice of my method in producing the device, whereby the objects contemplated are achieved, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, in which:

Figure 1 is a plan View of the device embodying the present invention as it is formed in a mold.

Figure 2 is a plan view of the device in completely assembled form with portions broken away and shown in section to illustrate details of construction.

Figure 3 is a plan view of the reinforcing member.

Figure4 is an duter end view of the button,

showing the formation of openings, preparatory to insertion of the reinforcing member in the device.

Figure 5 and Figure 6 are transverse sectional views, taken substantiallyas indicated respectively at line 5-5 on Figure 2 and line 6--6 on Figure 1.

The improved pessary embodying the present invention, and as illustrated in the drawing, includes preferably, but not by way of limitation, a unitary body as indicated at I0, formed of pliable, resilient material such as pure gum crepe. The body is composed of an elongated stem Il, preferably of flattened cross section, to one end of which is integrally connected a mushroom shaped button I2. pair of closely spaced apart, longitudinally extending ducts 14, which extend from the free end of the stem to the .opposite end and through the button, opening to the outer surface of the button, as clearly seen in Figure 4 of the drawing. The free .end portion of the stem, for a substantial portion of the length thereof, is formed with a contour, in the general appearance of a figure eight in cross section, such as may be seen in Figure 6 of the drawing, so as to provide a relatively uniform thickness of gum crepe, in the nature of a wall, around the respective ducts I4. Said free end portion of the stem is bifurcated longitudinally adjacent the middle thereof, intermediate the pair of ducts I4, as indicated at I6, so as vto provide two laterally separable, tubular leg portions I8.

The Vbutton I2 and the portion of the stem immediately adjacent thereto is slit between the ducts I4, as indicated at 20 in Figures 2 and 4 of the drawing, for accommodating the closed loop end 22 of a resilient reinforcing member 23 when the latter is inserted into the stem Il. Said member is of generally hairpin shape formation and is preferably, though not necessarily, formed of non-corrosive metal. The leg elements of the reinforcing member, as indicated at 24, have their extreme ends, as indicated at 25,

Acrimped inwardly to provide rounded terminals.

The body is formed with a The reinforcing member is inserted in proper position in the body I0, by projecting the legs 24 thereof into the ducts I4, from the button end, so as to position said leg elements 24 in the tubular leg portions I8 of the stem, and dispose the closed loop end 22 in the stem, as seen in Figure 2. After said reinforcing member is properly positioned within the stem, the lower prtions of the leg elements of the reinforcing member are bent as indicated in dot and dash outline in Figure 3 to yieldingly urge the tubular legv portions I8, of the stem apart.

After the reinforcing member has been inserted in position in the stem, the open ends of the leg portion I8, and the open ends of the ducts I4 in the outer surface of the button, are coated with or dipped in latex, or other suitable material, for sealing the ends of the ducts, as may be seen in Figure 2 of the drawing, If desired, a quantity ofthe latex or other suitable material, may also be introduced into the slit of the button and also into the ducts M immediately above the looped end portion 22.01? the reinforcing member, to more securely maintain said member in the position seen in Figure 2 of the drawing.

It will be noted from Figure 2 of the drawing that the closed looped end of the reinforcing member is positioned in the stem, a substantial distance away from the button, so as to permit free flexing movement of the button relatively to the stem for readily accommodating the device to variousianatomical iiections of portions of the body.

The ducts i4 formed inthe body I0 are preferably of cross sectional dimensions greater than the cross section dimensions of the leg elements 2li of the reinforcing member so as to provide a substantial clearance around the legs of the reinforcing member, as may be seen in Figure 5. This constructional feature is relatively important. When the device is disposed in proper position of use, the leg portions I8 of the stem, which are of plialble, resilient material such as Agum crepe, are yieldingly urged into firm engagement with the walls of the. cavity ofv the uterus and its` cervix, and when there is relative anatomical movement of the walls of the uterus, the yielding urgence of the leg portions I8 of the stem against said canal walls will permit free relative movement of the leg elements 24 of the reinforcing member, with respect to said leg portions I8., of the stem, and4 thereby preclude the possibility of frictionalV abrasion on the deli-cate tissues or membranes constituting part of the wall of the uterus. Y

Formed on the stem II, in surrounding relationV thereto, at an area intermediate the button and the bifurcated portion indicated at I6, is one or more relatively thin, substantially circular, disks 26, herein shown as two in number. These disks are preferably formed as an integral part of and of the same materials as the .body I0. The disks are preferably notched, at their outer peripheral edge, as indicated at 2, so that when the pessary is. inserted in proper position of use, due to the direction of insertion thereof in the cervix of the uterus, and the pressure of the Wall thereof on the marginal portions. of the disks,

'causes the disks to assume a, substantially frustoconical form, such as indicated in dot and Vdash outline in Figure 1 of the drawing. The frustoconical formationof the disks is such that the Vlateral surfaces. thereof extend in an outwardly direction toward the. button I2. Due to this for- 'mation'of the disks, said disks serve the purpose 4 v of valves and tend to preclude entrance of for-V eign substances into the uterus and its cervix while permitting flow of normal discharges from the uterus. The disks also serve as sanitary protective devices and tend to prevent iniiow of infectious matter into the cervix and uterus. .Due to inherent resiliency of the disks, they tend to hug the walls of the vaginal canal and thus, in

addition to the purposes above stated, also tend to assist the outwardly urged leg portions I8 of the stem in maintaining the pessary in proper position in the vaginal canal.

It will ibe observed that my novel pessary construction is composed of only two separate elements, by virtue of which there results a sub stantial saving of time and material in construction and assembly thereof.

Some changes may be made in the details of the construction and arrangement of the parts of the device embodying the present invention, as well as in the method of producing the same, without departing,r from the real spirit and purpose of this invention, and it is my intention to cover by my claims any modifie-d forms of structure or use of mechanical equivalents or variance in modes of producing the device all of which may bereasonably included within their scope.
