Abstract:
An ostomy appliance comprising a body side member comprising an adhesive wafer for securing the appliance to the user's skin, said wafer having a hole for receiving a stoma, wherein the body side member comprises first substantially annular coupling means for releasable attachment of a separately exchangeable receiving bag to the body side ostomy member for receiving secretions from the stoma, said receiving bag comprising matching substantially annular coupling means, wherein the body side member comprises a separate sealing member for sealing against the stoma, wherein the separate sealing member is in the form of a disc having a centre hole for accommodating the stoma and wherein at least the skin-contacting surface of the disc comprises a mass of a adhesive, wherein the disc facing the skin of the user has a maximum outer diameter corresponding to the inner diameter of the first annular coupling means and wherein the centre hole of the disc has a diameter smaller than the diameter of the stoma-receiving hole of the body side member ensuring that the disc covers all of the surface of the adhesive wafer facing away from the user located between the first annular coupling means and the stoma, said disc being made from a material that may be detached, rinsed and reapplied offers a body side member comprising a sealing member which may be removed. washed and reused, which has a service time at least as long as the body side member, and which reduces the frequency of stressing the skin around the stoma due to exchange of the body side member by protecting the surface of the adhesive wafer from soiling by and attack from the aggressive visceral contents and facilitates the cleaning of the body side member.
Abstract:
The application discloses a body waste collecting device comprising a collecting pouch and an adhesive wafer for attachment to the skin, said wafer comprising a backing layer and a first and second layer of hydrocolloid adhesive, where the second layer of hydrocolloid adhesive is at least partly interposed between the first layer of hydrocolloid adhesive and the backing layer, the first and second adhesive layers consisting of a continuous phase and a discontinuous phase,wherein a)the discontinuous phase of the first adhesive layer comprises pectin, carboxymethyl cellulose, gelatine, guar gum, and potato starch, b)the discontinuous phase of the second adhesive layer comprises carboxymethyl cellulose, gelatine, and guar gum, c)the composition of the continuous phase of the first adhesive layer comprises a polyisobutylene, a styrene block copolymer, a butylrubber, and a tackifier, d)the composition of the continuous phase of the second adhesive layer consists of polyisobutylene and styrene block copolymer.
Abstract:
An ostomy device that comprises an adhesive wafer (1) for attaching to the skin around the stoma. The wafer comprises an adhesive layer (3) having a proximal adhesive surface and a distal surface. The distal surface is covered with a backing layer (2). The wafer comprises a central portion (6) and a peripheral portion (7), and it comprises at least a first and a detection zone (4), wherein the detection zone is configured to provide a tactile sensation on the distal surface of the wafer when exposed to moisture.
Abstract:
An ostomy appliance comprising a front wall and a rear wall of flexible material forming a bag, said rear wall having an opening for receiving a stoma, and said rear wall also being provided with an adhesive wafer for securing the appliance to a user’s skin, said wafer having a first hole being aligned with the opening for receiving the stoma, wherein the opening has an edge being secured to the surface of the adhesive wafer facing away from the user in an attachment zone surrounding the hole of the wafer, said ostomy appliance further comprising a sealing member having a second hole for receiving the stoma, wherein the sealing member has a flange projecting from an outer rim thereof, said flange having an outer diameter greater than the diameter of the first hole, and said flange comprising a skin-friendly adhesive at a first surface to be placed on the abdomen of an ostomate, and said flange comprising a second surface being capable of adhering to the adhesive at the surface of the wafer to be secured to the user’s skin enables the use of a sealing member together wit one-piece ostomy appliance.

Abstract:
The current invention relates to radially divided adhesive wafers for applying to the skin of a human, and which increases the wear time of such adhesive wafers. The adhesive wafer comprises an inner annular adhesive layer, an outer annular adhesive layer encircling the inner annular adhesive layer, an attachment zone for attaching a collection bag, provided on the distal side of the adhesive wafer, and connection means for mechanically connecting the first annular adhesive layer to the second annular adhesive layer, wherein the connection means comprises a first and a second connection area on the distal side of the respective first and second annular adhesive layers, wherein at least one of the connection areas are arranged in a radial distance from the radial edges of the respective annular adhesive layer. By providing an adhesive wafer as described, it has been shown that the time before a leakage occurs may be increased. In many cases, the leakage is even prevented. This results in the user being able to wear the adhesive wafer for a longer period of time.
