  • Patent number: 5429626
    Abstract: An ostomy appliance having a mounting member adapted to be secured to the periostomal skin surfaces of an ostomate is disclosed. The appliance includes a relatively rigid mounting plate having a centrally located aperture therethrough. The mounting plate defines a flat, annular flange portion radially extending from the aperture. An adhesive skin barrier is provided on a proximal side of the mounting member and defines a stoma-receiving opening. An adhesive web is provided on a proximal face of the flange to secure the plate to the ostomate. An ostomy pouch having a stoma inlet portal therein is adhesively secured to the distal face of the flange. The adhesive used allows repeated release and reattachment of the ostomy pouch to the mounting plate, while providing the requisite sealing and adhesion. This capability allows reuse of the pouch following cleaning, and avoidance of disposal problems, while assuring a secure seal.

  • Patent number: 5000748
    Abstract: An ostomy drainage receptacle comprising a flexible pouch having a stoma-receiving opening therein. A mounting assembly surrounds the opening, the mounting assembly comprising a stiffly flexible mounting ring having a flat annular rim portion sealed to the opening and a convex dome portion having a central stoma-receiving opening therethrough. The thickness of the convex dome portion gradually increases in radial directions from the rim to the stoma-receiving opening so that the dome portion may flex upon application of the receptacle to the body for a more secure seal. The receptacle has a relatively wide upper portion to provide space for a relatively large stoma and the increased width also provides a large adhesive area for application to the body.

  • Patent number: 4911699
    Abstract: A deodorizing ostomy drainage receptacle comprising a flexible pouch having drainage chamber defining walls therein and an opening in one of the walls. The opening is located in an upper portion of the pouch and is capable of receiving a stoma. An aperture is also desirably located in the upper portion of the pouch and permits gas to egress therefrom. A deodorant is attached to the upper portion of the pouch in the vicinity of the aperture and is contained in a separate bag so that the gas must pass through the deodorant before egressing from the pouch. The deodorant is generally a solid material such as activated charcoal.

  • Patent number: 4654037
    Abstract: An ostomy pouch having a self-contained irrigator for cleaning the pouch. The pouch comprises spaced front and back walls sealed about their peripheries to define a collecting chamber and has a closable bottom opening for draining the collected contents of the pouch for disposal. An opening is provided in one of the walls for receiving the stoma of a patient. A fluid distribution tube is located within the pouch and is provided with a multiplicity of openings so that a projecting end of the tube may be connected to a source of cleansing fluid to permit the contents of the pouch to be flushed from the pouch without removing the pouch from the patient's body.

  • Patent number: 4460359
    Abstract: A closure clamp for the drainage outlet of an ostomy bag is disclosed. The clamp comprises an elongated strip of stiffly flexible plastic material having a centrally located winding portion and a pair of closure wings integral with and extending from the ends of said winding portion. Each wing is hinged to the winding portion by thinned zones of separation so that the wings may be folded to overlie the winding portion. The centrally located winding portion has an integral arm parallel thereto and spaced therefrom to serve as an initial gripping member to facilitate the winding operation and the wings are provided with interengaging attachment members to hold the wings together in a clamped position to securely maintain the bag in its wound configuration about the winding portion.

  • Patent number: 4078567
    Abstract: An ileostomy pouch and mounting device for the pouch are disclosed. The pouch comprises a bag having a drain opening at one end and a stoma-receiving opening adjacent its other end. An O-ring is sealed to the periphery of the stoma-receiving opening and has an integrally molded skirt flaring radially from the O-ring. A mounting ring is provided for the pouch and has an annular body-engaging face and an annular peripheral groove extending radially inwardly toward the axis of the ring. The O-ring is received in the groove entirely around the mounting ring to securely fasten the bag to the mounting ring.
