(01. 128—127) This invention relates to a device of the nature of an instrument for inserting readily within a cavity of the human body an article, such as a pessary; especially for so applying such an invention is to provide an applicator device in the fabrication of which each of the foregoing desirable requirements will be satis?ed, and which will avoid certain departures from satis article of the type including a resilient annular rim and a body of elastic sheet material, (for example sheet rubber) ; and more particularly an applicator or inserter of the type having'a shank provided near one of its ends with an abutment to be engaged with the inner circumference of factory performance which have characterized M conventional devices of the same general type, ' these inconveniences including, among others: (a) the need for exertion of an inordinate amount of strength by the user in holding the said annular rim of the article at a suitable pessary stretched properly for accurate emplace- , 10 ment upon the cervix; selected region, whereby the pessary may be dis tended, by a suitable manual operation; may then be inserted within a body cavity, such as (b) the existence of undesirable projections upon the shank of the applicator, intended to aid in holding the pessary in its stretched position, the vagina, extending into position for applica but tending to irritate the circumjacent living i tion readily to an occluded part, such as the cervix, and may be released after having been tissues; superimposed thereupon. In order to be satisfactorily serviceable for 20 such an intimate operation, an applicator or inserter of this kind must conform to a sub stantial portion of the following requirements, Viz.; (1) The applicator must be of a unitary, self (0) the difficulty, common to several existing types of applicators, in releasing therefrom the distended pessary after its application; (d) the presence of enclosed sliding parts 20 which tend to entrain ?uids in their interstitial spaces, and corruptible matter which destroys the sterility of the device; , (e) the very annoying difficulty experienced in effecting disengagement of the pessary from 25 contained structure; (2) It will preferably be fabricated entirely of non-corrodible metal, or equivalent sterilizable the projections referred to above in “(12) ”, so as to be able to withdraw the inserter after the and non-corrodible material, with a shank mem diaphragm has been introduced; ber of suitable length and contour, and having means for distending the pessary or like article (f) the presence in certain of these devices of rods and springs which interfere with the de 30 and for applying the stretched device to the sirable use of a suitably curved inserter shank. cervix or like occluded organ; (3) The distending means will preferably be made of metal or like sterilizable material and of such ‘a character as to permit its securement to In providing for avoiding these inconveniences, and achievement of the ?rst stated objects, and others which will appear as the description of the particular physical structure selected for the applicator adjustably in such a manner as illustration and disclosure herein progresses, an to hold the article in its extended condition, available to be presented for the operation of emplacement, without requiring the exercise of 4 CD substantial digital strength by the user; (4) The essential features of the inserter should be capable of embodiment in a device of any desirable shape and curvature and which may be used with pessaries or like articles of 45 various lengths, interchangeably, without sub inserter has been provided of the generally 30 stitution of component parts; (5) The applicator should be characterized by a smooth, non-irritant formation of its various parts; (6) It should be of simple structure, easy and inexpensive to fabricate and to maintain in working condition, and economical to produce in curved form which is disclosed in a co-pending application of ‘Rene M. Hay, Serial No. 679,221 ?led July 6, 1935, for Medical appliances; the shank of which terminates in a grooved head or abutment adapted to be engaged with the inner circumference of the resilient annular rim of the pessary, while at the other end a hook may be provided for convenience in manipulation. 45 In order to permit the elastic diaphragm struc ture of the pessary, to be placed under tension, and distended to present it in appropriate condi tion for superposition upon the cervix; and also to permit the distended pessary to be held in such extended position without the exertion of an appreciable amount of strength by the user, a quantities; its component parts being of readily ?exible tension member is provided, having at standardizable form. Under such conditions, an object of the present pessary at a region remote from the rim portion 55 one end a hook for engagement with the rim of 2 2,127,946 engaged with the abutment of the inserter, and means whereby the ?exible member may be connected selectively at various points along its length with a region of the inserter shank intermediate its ends, so that the ?exible mem ber will be maintained in its adjusted position, and will in its turn hold the pessary for applica tion, without requiring volitional effort on the part of the user, whose attention can be devoted 10 exclusively to the operation of emplacement. In the accompanying drawing, like characters of reference have been applied to corresponding parts throughout the several views which make up the drawing, in which 15 Fig. l is a view in side elevation of an appli cator device in the construction of which the present invention has been embodied; and also showing in connection with the applicator a pessary distended and ready to be applied; Fig. 2 is a plan view of the shank member of 20 the applicator, shown separately; Fig. 3 is a view of the ?exible tension-applying chain member of the applicator device, shown separately; 25 Fig. 4 is a view in side elevation of the shank tissue, as a result of the improvements which characterize applicant’s invention. By having a su?icient number of beads l8 on the chain, and by providing in the shank of the 1O inserter, a hole as M of suitable size and cross section, it is possible to use one inserter for any of the usual sizes of diaphragms that are now available. This constitutes a notable advantage of the novel inserter herein disclosed. 15 I have described what I believe to be the best embodiments of my invention. I do not wish, however, to be con?ned to the embodiments shown, but what I desire to cover by Letters Pat ent is set forth in the appended claims. 20 I claim: 1. An applicator or inserter device for install ing in a cavity of the human body a distensible article, such as a pessary of the type having a resilient annular rim and a body of elastic sheet member of the applicator, shown separately. material; said device comprising an elongated In the now-preferred embodiment of the in vention selected for illustration and description shank having at one end an abutment adapted to be engaged removably with the inner circum~ ference of said annular rim; a flexible tension to permit ready and complete understanding of 30 the invention, the reference character A desig 35 is then a very simple matter merely to lift the hook 01f the diaphragm, which then is caused by its intrinsic ?exibility to assume its intended position in the cavity; and then the inserter, with its chain IT, can be withdrawn without danger of any injury to the tender circumjacent living nates generally an inserter device which is formed at one end with a hook-member l0 and at its other end with a head or abutment II, grooved preferably, as at l2, to be engaged with the inner circumferential region, as at l3, of the annular, somewhat sti?‘ly resilient rim l4 of a pessary of the diaphragm type, in the rim of which is en rolled a coiled wire spring, indicated by the dotted circle at IS. The hook member ID is used for withdrawal of the pessary. A pessary of this general type is disclosed in co-pending application of Rene M. Hay Serial No. 432,306, ?led March 1, 1930, for Pessaries and method of making the same, now Patent No. 2,101,255. The reference character I‘! designates general ly a chain of known type, including metal beads l8 and having at one terminal a hook l9 and at its other terminal a ball 20, these terminals lim iting the range of the chain’s adjustive and ac tuating movements through the ori?ce 2|, which is of keyhole shape and of suitable size at its larger end to permit free movement of the ball chain lengthwise. In use, the pessary 22 is assembled with the inserter device by so placing the portion 23 of the rim M of the diaphragm in the groove l2 on the inserter head or abutment, and the hook IQ of the chain is attached to the other end of the dia to phragm, the hook being so designed as to engage the rim properly and not to injure the rubber of member having near one end a hook device for 30 engagement removably with a region of said rim remote from said abutment; and means whereby said ?exible member may be connected at various selected points along its length with an interme diate region of said applicator shank, and serving 35 when placed under tension and so connected to distend said article to any desired and suitable extent for application. 2. An applicator or inserter device for install ing in a cavity of the human body a distensible 40 article, such as a pessary of the type having a resilient annular rim and a body of elastic sheet material; said device comprising an elongated metal shank having at one end a grooved abut ment adapted to be engaged removably with the 45 inner circumference of said annular rim; a ?ex ible metal tension member having near one end a hook device for engagement removably with a region of said rim remote from said abutment; and means whereby said ?exible member may be 50 connected at various selected points along its length with an intermediate region of said appli cator shank, and serving when placed under ten— sion and so connected to distend said article to any desired and suitable extent for application. 3. An applicator or inserter device for install ing in a cavity of the human body a distensible article, such as a pessary, of the type having a resilient annular rim and a body of elastic sheet material; said device comprising an elongated 60 shank having at one end a grooved abutment the diaphragm, adapted to be engaged removably with the inner As the chain ll rests normally within the ori?ce 2| in the inserter, the chain is now pulled until the diaphragm has been stretched to the tension desired, and is then pulled from below the device until one of the beads 18 catches in the slot por tion 24 of the hole in the inserter. The instru ment may then be laid down, as it grips the dia phragm ?rmly, and holds it taut. For the release of the diaphragm, after its in sertion, it is only necessary to disengage the bead under the slot in the hole of the inserter, by pulling the bead chain forward through the hole until the tension on the chain is relaxed, and it circumference of said annular rim; a ?exible ten sion member comprising a chain having near one end a hook device for engagement removably with 65 a region of said rim remote from said abutment; and means whereby a selected link of said chain may be secured removably to said applicator shank under tension, and serving when so se~ cured to distend said article to any desired and 70 suitable extent for application. 4. An applicator or inserter device for install ing in a cavity of the human body a distensible article, such as a pessary of the type having a resilient annular rim and a body of elastic sheet 75 2,127,946 material; said device comprising an elongated metal shank having at one end a grooved abut ment adapted to be engaged movably with the inner circumference of said annular rim; a ?ex ible tension member comprising a metal chain having near one end a metal hook device for en gagement removably with a region of said rim remote from said abutment; and means whereby any selected link of said chain may be secured 10 removably to said applicator shank under ten sion, and serving when so secured to distend said article to any desired and suitable extent for ap plication, and to hold it upon said applicator shank; said securing means being releasable by a simple pulling movement upon the chain to per mit the tension to be then relaxed, and to permit disengagement of the abutment and of the hook respectively from said rim, thus permitting said 20 article to assume the desired self-retaining posi ' 3 tion upon the part of the body upon which it is thus installed. 5. An applicator or inserter device having the features claimed in claim 1, in which a bead chain constitutes said tension member, the chain-hook 5 being attached near one end of the chain and said chain having constricted portions between the bead components, and having an enlargement at its free end; said inserter having in its shank a keyhole aperture through which to thread said chain, the aperture being of suitable dimensions to permit lengthwise adjustive movements of said chain, limited at one end of its range of adjust ment by said chain-hook, and at the other end of said enlargement, said keyhole aperture having its 15 walls disposed for engagement with said chain be tween any selected beads, and adapted to nip the chain when so engaged, holding it and the pessary under tension. 20 GRACE E.
