  • Patent number: 9629744
    Abstract: 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.

  • Publication number: 20090043271
    Abstract: A drainable ostomy pouch having a first, proximal, and a second, distal, elongate, flexible stiffening strip each made of a stiff plastics material and each having a width, a length substantially greater than the width, a first major surface, and a second major surface parallel with and opposed to the first major surface. The stiffening strips extend in a direction transverse to a longitudinal direction of the ostomy pouch in the vicinity of a drainage opening of the ostomy pouch. The first major surface of each of the stiffening strips are attached to an outer surface of each of the first and second side walls of a drainage portion of the pouch. The first major surface of each of the stiffening strips are provided with at least two spaced grooves extending across the width of the stiffening strips.

  • Publication number: 20050131360
    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
