18 Claims. '1

This invention relates to stoma receivers, sometimes referred to as colostomy appliances.

Certain operations are now performed on the himia-n body known as colostomy and ileostorny operations for the flower intestine or the upper intestine respectively, and these operations .require either the temporary or permanent formation of artificial outlets from the intestine usually through the abdomen. .An outlet so formed is called a stoma. The stoma remains. open at-least a considerable portion of the "time and it necessary to provide a receiver for the stoma to take the digested food material which passes through the same. In many instances-the stoma is located near the groin and large and bulkystor a receivers cannot be satisfactoril used unless the rigid parts thereof are duitesmal-l. On the other hand, it is almost necessary and certainly desirable that thestoma reoeivershave large capacity. While certain stoma receivers have heretofore appeared on the market, thereisa distinct necessity for improvements in the existing construc tions.

It is an ohject'of the present invention toqsr vide a novel and improved stoma receiver which can be conveniently and comfortably worn with out being noticeableunder the ordinary clothing, which will conform to the body movementa'whi h will have large capacity and yetwvhiehwill have but small rigid par-ts so that it can be wvorn close to the groin or elsewhere and which canioe maintained in a sanitary condition ateail times.

Another object or the invention is to provide such a stoma receiver which includes a comparatively rigid casing which will :fi-t over the stoma and a flexible bag which will hang down below the casing, the mouth of the bag being .so located that it can be placed intcommunication with the stoma and the mouth of the bag. being 'ispcsed within the casing so that it will baprotccted at all times by the casing to permitthe free flow of waste matter at all times from the stoma into the bag.

A further object is to provide a .stoma receiver which will not heat up the body unduly at the point where it is located.

Still another object is toprovide a stoma receiver including a bag which canbe easily cleaned, which can be positively sealed, which can be removed for emptying, and which can be held by the hands of the wearer and emptied readilyby the wearer without difliculty and without danger of soiling clothing of the wearer.

It is another object of the invention to provide a stoma receiver including a bag into which the stoma empties, there being. valve means associated with the bag which will permit the ingress of matter into thebag trom the stoma but which at the same time will prevent the egress of matter from the top of the bag.

Another object is to provide a highly sanitary type of stoma receiver including a bag formed of flexible, transparent plastic material so made that the bag Will hangnatutally against the hody of the wearer but yet whiohha-g can expand as material enters the same so that the bag Will have large-capacity.

Another object is to provide a stoma receiver which rigid parts of .asmal-l size so that the rigid parts of the stoma. receiver can be located close to the groin-and yet the stoma receiver will have large capacity.

The objects and advantages of the present in.- vention will more fully appear fromthe following description made. in connection with the accentpanying drawings wherein like reference characters refer to the same or similar parts throughout the various views and in which:

Referring first to the embodiment of the invention shown in Figs. 1 to 14, there is provided, in accordance with the invention, a casing formed of relatively rigid material and including an inner casing section A and an outer casing section B. The inner casing section A is of circular shape in side elevation. In inwardly spaced relation from its periphery it is provided with a suitable stoma receiving opening lii, which is shaped to receive a stoma and is usually circular as shown although in some instances it may be of somewhat oval shape, depending on the shape of the stoma of the individual that the receiver is adapted to fit. The inner surface of the inner casing section A is preferably somewhat convexly formed as shown and this surface is made quite smooth. At its periphery the inner casing section A is provided with an outwardly extending grooved flange 20. Inwardly from the flange 253 and circumscribing the stoma opening 19, the inner casing section A is equipped with an outwardly extending grooved flange 2|, the groove being formed in the exterior portion of this flange 21. A small gas vent 22 is cut through the base of the flange 2| inwardly from the groove thereof.

The outer casing section B is of somewhat greater than semi-circular shape in side elevation and it is dished at its inner side. It has an arcuate grooved fiange 23 adapted for cooperative removable interlocking engagement with a portion of the grooved flange 2E! of the inner casing section A. When the two casing sections are so interlocked, a portion of the outer casing section B overlies the stoma receiving opening is? of the inner casing section in spaced relationship utwardly therefrom for the purpose of protecting this opening and preventing closing of the same by the clothing of the wearer. The two casing sections are securable together by springing the outer casing section B slightly, the material employed for making the casing sections being preferably a translucent or transparent plastic having enough elasticity to permit of sufficient distortion of the outer casing section B to engage and disengage the same from the inner section.

It will be seen that the outer section B closes a portion of the inner casing section A and normally this closed portion is placed uppermost, leaving a slot 24 in the lower portion of the casing and between the lower edge of the outer casing section B and the outer portion of the inner casing section A. The outer casing section B has a circular depression formed in its outer portion With a button 25 projecting outwardly from the center of this depression, and this button and depression are for the purpose of permitting attachment of the casing to a belt 26 carrying an adjustable buckle 2'! at one end and a buckle engaging hook 28 at its other end. This belt is adapted to fit aroundthe body of the wearer, as around the waist, and it has a buttonhole 29 formed by slotting a portion thereof, whereby the button 25 may be engaged with the belt. The casing section B is depressed adjacent the button 25 so that the belt will fit within this depressed portion to limit the thickness of the combined casing and belt.

For use with the casing thus described, there is provided a bag 0 of special construction. This bag is preferably formed of flexible transparent or translucent plastic material, and it is either molded or produced by dipping a form into the liquified plastic. The bag C has a circular mouth portion at integrally connected with a ring 3| and the ring and mouth portion are adapted to releasably engage the flange 2| of the inner casing section A within the groove of this flange. Assuming that the ring 3| of the bag is disposed in a vertical plane, the bag projects downwardly therefrom in the same general plane as the plane within which the ring is disposed. In other words, the mouth of the bag is at one side of the bag rather than at the top of the bag. The width of the bag is reduced somewhat below the mouth 53o to form a neck 32, which is received within the slit 2G aforementioned. Below the neck 32 the body 33 of the bag is enlarged laterally until the bag is again reduced in width near its lower end to form a reduced outlet portion 34, the lower end of which is open to form an outlet 35 for the bag. The neck 32 and the body 33 are provided with corrugations 36, these corrugations being provided for several important purposes. The corrugations cause the bag to assume small size when not filled or partially filled but yet permit the distention of the bag so that it will have large capacity as the bag is filled. The bag normally hangs from the casing formed by the two casing sections A and B as indicated in Figs. 2 and 10, and of course the bag will rest against a portion of the body of the wearer. The corrugations 36 formed in the bag permit air to work between the bag and the body of the wearer, thereby keeping the body cool at this point and preventing undue sweating and heating of the body. In other words, the ribs of the corrugations 36 are the only part of the bag which come in contact with the body and as a result there is much less discomfort to the wearer than in the case of a smooth surfaced bag.

The ring 3! has sufiioient elasticity to permit it to be readily carried over the outer portion of the flange 2! to fit the bag onto this flange and to permit removal of the bag from the flange. In order to permit of ready removal of the mouth of the bag from the flange, a small tab 3? secured at its upper end to the ring 3! is provided whereby the reinforced portion of the bag can be pulled upon to disengage the mouth or" the bag from the flange. To close the lower end portion 34 of the bag and'yet to permit easy emptying of the bag without danger of soiling the clothes of the wearer and by use of only the two hands of the wearer, I have developed a special construction. A flexible tab 38 has an upper circular portion which is molded into the inner side oi the bag near its lower end and this tab carries at its lower end a half snap fastener 39 which engages with another half snap fastener 40 attached to means the upperendrof a. second=flexible tab all, the.

tab 41% having an enlargementrZ atrits lower end. A channel member 43 of springconstruction and made of metal or hardened plastic has a projecting flange 4'5 at one side thereof provided with a keyway slot 45 within. which the tab 4| slidably fits. Accordingly the channel member A3 can slide upwardly or downwardly on the tab iii, the enlargement 42 preventing thetab from being pulled out of the keywayI slot unintentionally. If it should be desired to detach the channel member from the tab 4!, howeventhis can be readily doneby compressing the tab into one portion or" the keyway slot 45 and working the tab through the entrance notch of the keyway slot. The tab ii is made longer than the normal spacing between the lower end of the tab 38 and channel member t3 when the outlet of the channel member is closed to allow for ready securing of the channel member to the lower reduced portion of the bag. The sliding connection between the tab 4! and the channel member permits the channelmember '33 to slide upon the tab ll without bowing the tab and forming a bunch below the clothing of the wearer when the outlet 35 is closed. The channelmem-- ber 43 has a roller 46 connected to one end thereof by a pivot fill and this roller carries a handletB. The flanget't and the opposing flange ofthe channel member are curved toward each other slightly to form a spring entrance mouth which will resiliently receive the" roller 56-. By

carrying the lower reduced portion 8 3 of thebag C around the roller 66 in a bight and then swinging the roller it into the channel member 43 through its entrance mouth, the channel member and roller 115 will have a clamping action on the bight of the reduced lower end portion 34 of the bag to tightly secure it and prevent any leakage of the contents of the bag C through the, outlet opening 35 while not injuring the lower end portion 34 of the bag. Opening and closing of the lower portion. ofthe bag can be accomplished by one hand of the wearer either while the bag is attached to the casing or when it is detached and held by the other hand of the wearer. Thus the fingers of one hand may grasp the channel member 43 andthe thumb of the same hand can be engaged with the handle 48' to swing the roller 46 out of the channel of channel member 43. The strap connection between the channel member 33 and the bag prevents the clamping mechanism. being. lostwhen.

the lower end of the bag has been opened.

In some instances it may be desirable to use with the stoma receiver a valve. member. D to permit the ingress of matter into the. bag, C while,

preventing the back flow of. matter through the mouth of the bag. As shown in Figs. 2, 7, 8, and.

9,, the valve member D comprises a. dome-shaped body having a grooved flange at its periphery, the groove being on the external side of this flange and the grooved. flange engaging the portion of the inner casing section A surrounding thestoma receiving opening 19. The valve member. is made preferably of. flexibleplastic or rubber andv it has. a flat discharge spout portion 48 terminating in,

an. outlet 511. The side walls. of thespoutportion t9 are very narrow so that rather wide. lips are formed, the, lower portions of which. are nor-- mally in contact with each other topreventthe re-entrance of matter back into the dome portion of thevalvemember after this matter has once passed through the spout portion :19. The lips of the valveimemberarediagonally cut as shown in:.Figs;i"7xand 8. inasmuch as with such a cori valve. are provided With rounded contours 5i pro-- ducing the back-sealing action.

In Figs. 16 and 17 there is shown a bag F similar in all respects to the bag C previously" described with the exception that a valve mem berG is formedintegral with the upper portion ofthe bag. This valve member G is much on the order of the valve member D firstdescribed with the exception that it is larger and the edges of the domed portion of the valvemember G are integrally formed with the mouth portion of the bag F.

In certain instances where the stoma is located very close to the groin, it may be desirable to provide an inner casing section H, such as that shownin Fig. 18, which is in all respects similar to the inner casing section A previously described withthe exception that the stoma receiving. opening 52 formed in the casing section I-I eccentrically disposedrelative to the periphery of the inner casing section instead of concentrically located as in the case of the inner casing sec tion A. The eccentric disposition of the opening 52' makes it possible to fit the casing very close to the groin.

In Figs. 2 and lo a portion of the skin of the human body is designated bythe letter J and attached to this skin is a stoma S, it being understood that the stoma S willconnect with either the large or small intestine. In mounting. the stoma receiver on the body, a suitable absorbed pad 53-, having a central aperture through which any protrusion of the stoma extends, isplaced against the skin, and thereupon the receiver in its assembled condition will be applied against this pad at the exterior thereoiwith the stoma in direct communication with the dome portion of the valve member if a valve member such as D, E, or G is employed, or'in direct communication through the stoma receiving opening 19 or 52 with the upper portion of the bag C if no valve member is used. The absorbent pad 53' is preferably made of cellulosematerial. having high absorbent qualities and having numerous plies, preferably backed by crepe moisture repellant material. This pad cushions the effect of the casing'against the body and it prevents the spread of the waste matter discharged through the.

stoma S to the skin adjacent the stoma. After the belt and casing have been applied and the belt'Zfi has beerrmounted. on thebody, the'belt can be adjusted so that the button 25 be, conveniently received in the buttonhole whereupon the device is ready for service.

As'the major part of the: bag does. not fit within the casing consisting of the inner and outer sections'A and B or H and B, as the case. may be, the" rigid parts ofthe" receiver can .be made quite small and yet the bag. will have large capacity. The major part of' the receiver will yield" with bodymovements so that the device will be unnoticeable when worn under the clothes and also. the receiver can be used in conjunction with a stoma located very close to the groin without? inconvenience to the" wearer.

The material dlscharged from the stoma can readily flow into the bag and the corrugations of the bag will allow the bag to distend as material flows into it so that, while the bag occupies but small space when not filled, it can expand and a large volume of material may be accommodated within the bag. If one of the valve members D, E, or G is employed, this will prevent the back flow of material through the receiving mouth of the bag while at the same time permitting the free ingress of material emptying from the stoma. When it becomes necessary to empty the bag C, this can be readily accomplished by the two hands of the wearer. The vent 22 will permit the discharge of gas.

Preferably the bag and the inner and outer casing members A, B, and H will all be made of transparent or translucent material which can beeasily cleaned and sterilized so that the device can be maintained in sanitary condition at all times. The parts can be readily taken apart for cleaning.

It will be seen that a highly satisfactory stoma receiver has been provided having many ad vantages.

It will of course be understood that various changes may be made in the form, details, arrangement, and proportions of the various parts without departure from the scope of the present invention which, generally stated, consists in the matter shown and described and set forth in the appended claims.
