Abstract

An enterostomy drainage bag having front and rear walls of flexible moisture-proof material forming a fluid collection chamber therebetween. A stoma-receiving opening is formed in the rear wall and is surrounded by disc means for attaching the bag to the body of a patient and for sealing the opening against leakage. An opening is formed in the bottom of the bag and communicates with a valve for draining collected fluid from the bag when filled. A rib assembly having a generally oblong, openended, U-shaped configuration is mounted on the front wall of the bag within the fluid chamber to prevent sealing of the stomareceiving opening and bottom drain opening. A plurality of slits is formed in the rib assembly so that the bag and rib assembly will flex and bend with the body movements of a wearer. The drain valve is adapted to receive an end of a flexible tube which can be connected to a larger remote collection container permitting the appliance to be used during the inactive nighttime period.

Claims

1. An enterostomy drainage appliance of the type having a flexible bag with at least front and back walls forming a fluid collection chamber therebetween, in which a stoma-receiving opening is formed in the upper end of the back wall, and in which means are provided for mounting the bag on the body of a patient and for sealing the back wall opening with respect to a stoma;

the improvement including, flexible rib means having a generally elongated inverted U-shaped configuration mounted on the front bag wall and located within the collection chamber;

said rib means comprising a pair of spaced straight leg portions extending longitudinally within the collection chamber and terminating at their upper ends in an integral curved portion to form the Ushaped configuration;

fluid drainage channel means being formed between and by said leg and curved rib portions;

the curved rib portion being located adjacent the upper bag end substantially opposite the stoma-receiving opening and substantially surrounding said stoma-receiving opening when the front wall is pressed towards the back wall; and

said stoma-receiving opening communicating with the channel means within the curved rib portion when the rib means is pressed against the rear wall to prevent sealing of the stoma-receiving opening by the bag front wall and to provide a continuous open drainage channel extending from the stoma-receiving opening generally throughout the length of the collection chamber between the straight leg portions.

2. The construction defined in claim 1 in which drain opening means is formed in the lower end of the bag and communicates with the collection chamber;

and in which valve means is mounted on the bag for opening and closing said drain opening means.

3. The construction defined in claim 2 in which the rib leg portions terminate in lower ends;

in which said lower ends are located adjacent the drain opening means and on opposite sides thereof; and

in which the channel means communicates with and extends between the stoma-receiving opening and said drain opening means to provide a continuous open fluid drain channel when the rib means is pressed against the rear bag wall.

4. The construction defined in claim 3 in which the rib leg lower ends are flared outwardly to reduce twisting of the flexible bag in the area adjacent the drain valve means and to prevent closing of the drain opening.

5. The construction defined in claim 2 in which means is formed on the valve means for detachably mounting a flexible tube thereon.

6. The construction defined in claim 1 in which the curved and straight leg portions of the rib means are formed of a non-absorbent semi-rigid rubber material;

and in which a plurality of transversely extending slits are formed in the straight leg portions and are spaced longitudinally therealong to provide flexibility to said leg portions.

7. The construction defined in claim 6 in which the curved and straight leg portions are generally rectangular in cross section having top, bottom, and inner and outer side surfaces;

in which the bottom surfaces are secured to the front wall of the collection bag; and

in which the slits are formed in the top surfaces of the straight leg portions.

8. The construction defined in claim 7 in which the top, bottom and outer side surfaces of the curved rib portion are flared outwardly to provide a broad area of contact when the rib means is pressed against the body of a patient.

9. The construction defined in claim 7 in which the inner side surface of the curved rib portion has a semicircular configuration with a radius slightly larger than the radius of the stoma-receiving opening in the back wall;

and in wHich said semicircular configuration is concentric to the stoma-receiving opening when the rib means is pressed against the back wall of the appliance bag.

10. The construction defined in claim 9 in which the outer side surface of the curved rib portion forms a generally three-quarter circular configuration;

and in which said circular configuration is concentric to the inner surface semicircular configuration.

11. An enterostomy drainage appliance of the type having a flexible bag with at least front and back walls forming a fluid collection chamber therebetween;

in which a stoma-receiving opening is formed in the upper end of the back wall; and

in which means are provided for mounting the appliance on the body of a patient and for sealing the back wall opening with respect to a stoma;

the improvement including generally inverted U-shaped rib means formed on the appliance front wall and extending longitudinally, generally throughout the length of the bag, within the collection chamber;

the rib means having spaced first and second straight leg portions and a joined curved portion joining said straight leg portions integrally at their upper ends;

drainage channel means being formed by said leg and curved rib portions;

the leg portions each having top, side and bottom surfaces, with said bottom surfaces mounted on the appliance front wall;

the rib means side walls having sufficient thickness to prevent the appliance back wall from readily sealing against the front wall within the drainage channel means when the front wall is pressed towards the back wall;

a plurality of transversely extending slit means formed in top surfaces of the straight leg portions;

said slit means being spaced longitudinally along the major portion of the leg portions permitting said leg portions to bend and flex with the body movement of a patient;

the integrally joined curved upper portion of the rib means being located substantially opposite the stoma-receiving opening so that said opening is located within the curved rib portion and between the leg portions when the front wall is pressed in a direction towards the back wall to maintain communication between said stoma-receiving opening and the drainage channel means;

drain opening means formed in the bottom of the collection chamber; and

valve means communicating with the drain opening means for opening and closing said drain opening means, said valve means being adapted for detachably mounting an end of a flexible tube for drainage of the fluid within the collection chamber to a remote storage receptacle.
