UNITED STATES PATENT OFFICE 2,667,167 COLOSTOMY POUCH

Paul A. Baiche, North Providence, R. I., assignor ^R“^bber Company, a corporation of Knode Island

Application November 16,1951, Serial No. 256,757 (Cl. 128—283)

Claims.

The present invention relates to the manufacture of medical equipment, and has particular reference to a novel construction for a colostomy pouch.

Tbe principal object of the invention is to provide a colostomy pouch with a gas retention device.

A further object of the invention is to position a gas retention element on a colostomy pouch, to receive gases which would otherwise exert discomfortable pressure or escape and cause embarrassment to the patient.

An additional object of the invention is to provide a colostomy pouch with a support for an inflatable gas retainer, which may be quickly ^m°™t^{ed and} Quickly detached by the patient.

With the above and other objects and advantageous features in view, the invention consists of a novel arrangement of parts more fully disclosed m the detailed description following, in conjunction with the accompanying drawings, and more specifically defined in the claims appended thereto.

In the drawings,

Fig. 1 is a front elevation of a colostomy pouch ^:embodying the invention;

L^{is an enl}arged sectional detail showing the bladder connection; and

Fig. 3 is an exploded view showing preferred connector parts.

^been found desirable to provide a gas retention device for a colostomy pouch, whereby the patient is spared discomfort resulting from ^{gases into the pouch and} embarrassment if the pressure is relieved by escape of the gases from the pouch. To this end, I form the pouch with an outlet connection to which an infiataole sac is detachably secured whereby the gases escape into the sac, the sac being readily removed and readily replaced by a clean sac.

Referring to the drawings, the colostomy pouch 10 is of standard type, having a bag 11 with flexiU nr ίΤ ^{walls l2}’ ^,3> ^an inflatable ring thAn ^de+^{d Wlth a center} opening 15 leading to the bag interior, and side tabs 16, 17 for receiving 45 the ends of a belt. The front wall 12 has an opening 18, preferably positioned just below the ring 14, and a connector base 19, see Figs. 2 and 3 is cemented thereto, the connector base having a exten^n ^e??° ^{a down}wardly inclined tubular 50 extension 21. ±he flange 20 has an opening 22 m alignment with the front wall opening 18 extons?nn^C9^ai^{imS Wlth the bore 23 of the} tubular

The lower, outer end of the tubular extension 55 is recessed to provide an enlarged bore 24 with an annular shoulder 25, whereby a threaded metal socket 26 may be lockingly inserted in the enlarged bore 24. A plug 27, of hard rubber or the like, is then threaded into the socket, with an intermediate rubber washer 28. The plug 27 has a projecting tubular portion 29, and is bored as indicated at 30 to provide a free flow passage ! for gases from the bag 11.

The tubular portion 29 has a laterally extending tip flange 31, see Fig. 3, whereby a flexible expansible sac 32 of thin rubber having a tubular neck 33 may be mounted on the tubular portion detachably locked in place by a rubber band ’ ^Tile tubular portion 29 i_s provided with disk wings 35, 36 which are in the same plane, for grasping by the Angers when mounting or dismounting the sac.

The waste gases from the pouch thus expand uuo the sac, which is made of very thin material as compared lo the body wall of the pouch, and the patient is spared the discomfort of gas pressure within the colostomy bag. Whenever an ac“^atlon,°^fJ^{as occurs}- ^{the patient can} excuse himself and then readily remove the sac, and replace it with a clean sac, thus avoiding embarrassment.

nTn? * ^hav® ^described a specific embodiment of the invention, it is obvious that changes in the size, shape, arrangement, and material of the parts may be made to meet different colostomy requirements, without departing from the spirit and the scope of the invention as defined in the appended claims.
