Abstract: A drainable ostomy pouch having sidewalls of flexible sheet material defining a cavity therebetween and a downwardly-extending neck portion terminating in a discharge opening that is closed by folding the neck portion upwardly and opened by unfolding the neck portion downwardly. Each of the sidewalls of the neck portion is provided with a transversely-extending bias member that is formed of stiff but flexible, springlike plastic material. The bias members are normally flat so as to be in straight parallel closed condition but are openable under inwardly-directed finger pressure applied to their opposite ends to cause them to bow outwardly away from each other.

Abstract: A drainable ostomy pouch comprising a first (1) or proximal and a second (2) 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 (8a) in the proximal side wall and an elongate drainage portion extending downwardly in a longitudinal direction and ending in a drainage opening (5) extending transversely to the longitudinal direction, a first (6) or proximal and a second (7) or distal flexible stiffening strip of relatively stiff material such as PET, nylon, high density polyethylene or low density polyethylene extending immediately adjacent to and along said drainage opening and being attached for instance by heat sealing or adhesion to the outer surface of the first and second side walls, respectively, of said drainage portion, the pouch further comprising a Velcro strip 9 on the wall 1 and a Velcro strip 10 on a flap 13 for securing a coil comprising the first and second stiffening strips rotated upwards
