PES SARY APPLI CATOR Filed Oct. 25, 1935 28 /5 IBCL INVENTOE. Lamas/var: Scum/c1153 A TTOR NEY5 Patented Dec. 14, 1937 PATENT OI-FI CE 1 rns saay mmca'ronf v Lawrence Schleicher, Angcl es, Calif; Application mm 25,1935, Serial No. 40,727

This invention relates to pessary applicators and has for its broad purpose the form and construction of an applicator for automatically placing the pessary over the cervix to completely cover same. 7

A further object is to provide an instrument adapted to be readily inserted in the vagina and manipulated so as to follow the posterior vaginal floor to prevent slippage of the pessary into the anterior cul-de-sac in the process of applying the pessary over the cervix.

' A further object is' to provide a pessary applicator having means for supporting the pessary in a position for application thereof over the cervix and for automatically effecting application of said pessary to the cervix by contact established therewith upon operative insertion of the pessary in the vagina.

Another object is to provide a pessary applicator which, by reason of the form thereof, will enable the instrument to be pressed against the vaginal floor andthe diametrically opposite posterior and anterior portions of the resilient rimof the pessary properly correlated with the anterior cul-de-sac and posterior cu'l-de-sac before the pessary is released -from the instrument, thus insuring complete closureof the cervix.

A still further object is to providean instrument the form of which will permit use of a much smaller pessary than was possible heretofore, the reason being that the instrument accurately effects association of diametrically opposite rim portions of the pessary with said posterior cul-de-sac and the anterior cul-de-sac instead of with the posterior cul-de-sac and the.

symphysis.

Another object is toprovide an instrument in which the resiliency of the pessary along a line drawn through diametrically opposite rim portions thereof will be taxed sufliciently to insure projection of the pessary over the cervixvthe moment the pessary is operatively related to the cervix but not before, the action just stated being wholly due to the tendency of the pessary to assume its normal contour or condition when the taxing pressure is relieved therefrom.

Another object is to provide an instrument which will permit of more sanitary handling of the pessary when applying same, the instrument itself being formed, constructed and designed to enable it to be sterilized after each use thereof and maintained in a sanitary condition.

In the drawing, wherein has been illustrated a preferred embodiment of the invention,

Figure 1 is a diagrammatic illustration of such 10 Claims. (Cl. 128-127) g the ejected or released parts of the female anatomy as is required to demonstrate the modus operandi when applying the pessary over the cervix, the instrument being shown fully inserted in thevagina and pressed v against the floor thereof to operatively correlate diametrically opposite rim portions of the pessary with the anterior cul-de-sac and the posterior cul -de-sac, the open side of the diaphragm of the pessary being directly over the cervix, whereby to completely cover same when the pessary is released from the instrument;

Figure 2 is. a view in plan of the instrument showing in dotted lines the stretched condition of-the pessary and operative association of the pessary with theinstrument preparatory to insertlng the instrumentin the vagina;

Figure 3 is a view partly in longitudinal section and partly in elevation. showing the pes ary latched ina stressed condition and illustrating the diaphragm well disposed directly over the trip device of the instrument to enable the diaphragm to be centered relative to thecervix when the diametrically opposite rim portions of the diaphragm are operatively associated with the posterior cul-de-sac and the anterior cul-desac for release of same therein as soon as .the I .trip device is made to contact the cervix;

Figure'4'is a view similar to Figure 3 showing from the instrument following lateral contact of the trip device with the cervix.-

The term "pessary employed herein shall be construed to mean any soft elastic diaphragm, cupped or otherwise formed, and adapted to completely close the cervix, the same possessing sufflclent inherent resiliency to enable it to be stressed along a line diametrically passing through portions of the resilient rim of the pessary to enable said portionsrto be applied respectively, to the posterior cul-de-sac and the an terior cul-de-sac. h p

In carrying the invention into practice, use is madeof an instrument characterized by an attenuated handle Ill of suflicient length'for insertion of the instrument into the vagina until the rounded smooth end ll thereof is fully pressed against the wall of;the posterior cul-desac A and the end 12 vdisposed at the anteriorcul-de-sac B, as shown in Figure l.

Theheadii! of the instrument of which the smooth surfaced ends H and I2 are a part is substantially ovate and channeled at one side as at H to confront. the cervix and provided at its opposite side with a smooth. convex surfacev l5 running longitudinally of the instrument and positionv of the pessary adapted to be pressed against the lower wall or floor of the vagina to insure enlarging the vaginal passage sufficiently to enable the ends ll similar depression l1. At 0 is showna pessary 7 consisting of a highly elastic rubber diaphragm I. having a bead Ila enclosing the usual form of endlessspring ring IS. The distance from channel It to channel I] is slmhtly greater than the normal interior diameter of the rim is at any place in the circle of said head, Wherebywhen the open side of the pessary is elongated, substantially diametrically opposite portions of the bead will be held temporarily confined in the respective channels l6 and H, as will be'fully appreciated on reference toFigures 2 and 3 of the drawing. When the pessary is applied to the instrument as just stated, it is to be borne in mind that the normal open side of the pessary faces towards the cervix when the instrument is fully inserted in the vagina. s

A combined latching and pessary tripping mechanism is employed to hold the pessary operatively supported upon the instrument and same includes a tiltable latch element 10 pivoted at 200. in the channel ll of head is, the same having a nose II, the grooved face 12 of which directly faces the channel II to thus press against the inner surface of the bead II at one side of the pessary and thereby hold the bead confined in said channel when the latch occupies the position shown in Figure 3.. It is in this general manner that the pessary is held elongated along a line running from the channel II to channel ll longitudinally of the head II.

The tail 23 of latch 2| is provided with a lug 24 adapted to be engaged by a tiltable dog 25 pivoted at 250 in channel ll of said head I! when the pessary is fully applied as shown in Figure 3. This dog'forms a part of a link I. having pivotal connection at 2! with one end of a tiltable trip element It pivoted at 28a in said channel It. A U-shaped spring 28 is secured at one end to the head I! and freely bears at its other end against the underside of the trip element 2! to co-act therewith in normally urging the dog 25 to the position shown in Figure 3.

Contained in channel It is the holding means and disposed to contact the cervix and actuate the holding means to release stress from the pessary and enable the pessary to be applied over the cervix in response to'inherent springiness of the pessary and tendency of the pessary to assume its normal state.

The pessary is applied to the instrument as shown in Figure 3. The handle 10 is held in the hand and the head II thereof inserted in the vagina with the smooth convex surface of the head in slight pressing contact with the floor of the vagina. This is in order that thevaginal passage may be enlarged sufficiently to enable the open side of the pessary to coincide with the cervix and also enable the substantially diametrically opposite gripped ends of the bead Is to be laterally correlated, respectively with the posterior cul-de-sac and the anterior cul-de-sac. when fully inserted as shown in Figure 1, the cervix will be made to contact the tripping device 2|, so as to start the element Ii in a releasing direction. The parts II and II instantly assume the positions shown in Figure 4, and under the natural resilient action of the pessary the latter automatically moves in the direction of the arrow in Figure 4 and is applied directly over the cervix and diametrically opposite portions of the bead Ila operatively associated with the posterior cul-de-sacland the anterior cul-desac, as aforestated.- With this accomplished, the instrument can be readily removed from the region without dislodging the pessary from the cervix. 1

To the best ofmy knowledge, it is entirely new in the art to provide a pessary applicator formed, constructedand designed to enable automatic adjustment of a pessary over the cervix by contact of a part of the instrument with the cervix and this feature will be broadly claimed herein, it following thatfvarious changes in the construction of the device can bemade without departing from the spirit of the-invention.
