A drainable ostomy pouch is disclosed which comprises a first or proximal and a second or distal side wall of flexible sheet material sealed to each other for defining a cavity therebetween for receiving human stomal discharge through an aperture in the proximal side wall. It includes an elongate drainage portion extending downwardly in a longitudinal direction and ending in a drainage opening extending transversely to the longitudinal direction, and a first or proximal and a second or distal flexible stiffening strip of relatively stiff material extending immediately adjacent to and along the drainage opening and being attached to the outer surface of the first and second side walls, respectively, of the drainage portion. The pouch further comprises a securing strip having interlocking elements on the wall and corresponding interlocking elements on a flap for securing a coil comprising the first and second stiffening strips rotated upwards at least two times.

The invention claimed is: 1. A drainable ostomy pouch comprising a proximal and a distal side wall each including a liquid and gas impermeable film, said films being sealed to each other for defining: i) a cavity formed of said films for receiving human stomal discharge through an aperture in said proximal side wall and ii) an elongate drainage portion formed of said films in communication with said cavity and extending downwardly from said cavity in a longitudinal direction thereof, said elongate drainage portion ending in a drainage opening defined by the lower ends of said films extending transversely to said longitudinal direction, a proximal and a distal flexible stiffening strip of relatively stiff material extending immediately adjacent to and along said drainage opening and being attached externally on said films to the outer surface of said proximal and distal side walls, respectively, of said drainage portion, said proximal and distal stiffening strips being capable of flexing toward and away from one another to control the rate of drainage of the pouch by opening and closing the drainage opening defined by the lower ends of said films, said films of said proximal and distal side walls of said drainage portion being separated to open said drainage opening when said proximal and distal stiffening strips are flexed away from one another, the pouch further comprising a flap of flexible material having an edge portion attached to one of said side walls in spaced relation to said proximal and distal stiffening strips, said flap of flexible material also having a first securing strip of an interlocking means on a portion of said flap that can be rotated relative to said one of said side walls about an angle formed between said edge portion and the remainder of said flap, and a second securing strip of a corresponding interlocking means attached to the other of said side walls intermediate said proximal and distal stiffening strips and said flap of flexible material for securing a coil comprised of: i) said proximal and distal stiffening strips rotated upwards at least two times and ii) said second securing strip, said coil fitting snugly and tightly in said angle formed between said edge portion and the remainder of said flap with said interlocking means of said first and second securing strips in engagement.
