  • Publication number: 20110118684
    Abstract: An adhesive ostomy coupling comprises first and second coupling parts each having a respective orifice. The first coupling part includes an upstanding wall for entering the orifice of the second coupling part. The second coupling part includes an adhesive faceplate for adhering to the first coupling part outside the upstanding wall. The upstanding wall and the faceplate form an interference fit at a position corresponding to the inner periphery of the adhesive, to protect the adhesive from effluent attack. The upstanding wall has an undercut for interlocking with the adhesive faceplate of the second coupling part. The upstanding wall also acts as a guide to prevent mispositioning of the pouch when mounting the adhesive faceplate on the complementary flange.

  • Publication number: 20110071485
    Abstract: An adapter is disclosed for an ostomy coupling. The adapter provides a floatable coupling characteristic to an ostomy body fitment that has a non-floatable coupling part. The adapter comprises a first coupling part for attaching to the non-floating coupling part of the body fitment, a second coupling part for releasably attaching to an ostomy appliance, and a flexible collar between the first and second coupling parts. The flexible collar permits the second coupling part to be displaced away from the first coupling part, thereby creating a space for an ostomate to manually brace the second coupling part against an attachment force when an appliance is fitted.

  • Publication number: 20110066091
    Abstract: The proposed device includes two segments adapted to enclose a body part in a form-fitting manner. Each segment contains an electroactive-material-based actuator, which is adapted to receive an electrical control signal and in response thereto adjust the actuator's morphology, so as to cause the segment to apply a basic pressure profile to the body part. A pressure transition is adapted to redistribute the basic pressure profiles between the first and second segments. A control signal in respect of the first segment causes the pressure transition system to apply a first adjusted pressure profile to at least part of the second portion of the body part, and vice versa, a control signal in respect of the second segment causes the pressure transition system to apply a second adjusted pressure profile to at least a part of the first portion of the body part.

  • Publication number: 20110040269
    Abstract: A medical device such as a controlled discharge ostomy appliance comprises a fluid filled seal for sealing around a body orifice (stoma). The fluid filled seal comprises a fluid chamber including a fluid impermeable membrane that forms a movabable wall of the fluid chamber, one or more ports communicating with the chamber; and resilient foam disposed within the fluid chamber. The foam tends to expand the chamber to seal against the body. The port controls the inlet and exhaust of fluid from the chamber, in response to movement of the body away from, or towards, the seal.

  • Publication number: 20100211033
    Abstract: A urine drainage bag, such as a urostomy bag, includes a drainage tap. The tap includes a tap member mounted to a housing so as to be pivotably movable between a closed, stowed position and an open, deployed position. In the closed position, the tap member is accommodated substantially within a chamber of the housing. The housing is disposed between front and rear walls of the bag, such that the tap is integrated into the seam of the bag. The tap further comprises a drip cap that is captively mounted on the tap member. A portion of the drip cap acts as a handle for pulling on the tap member. A portion of the drip cap also acts as a retainer or lock for blocking accidental closing of the tap member when attached to a night drainage apparatus.
