Abstract: An ostomy appliance comprising: first and second walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening; a connection member connected to the first wall for attaching the appliance to a user; an aperture located in either of the first and/or second walls for permitting waste gases to exit the appliance; and a multi-layer filter positioned adjacent and covering the aperture on an exterior surface of the respective first and/or second wall. A layer of the filter is hydrophobic and the hydrophobic layer is positioned directly adjacent the respective first and/or second wall. The hydrophobic layer has a first side and a second side, where the first side is connected directly to the respective first and/or second wall, and the connection holds the multi-layer filter relative to the wall.

Abstract: An ostomy Appliance (10) including first and second walls (12, 14) connected to each other at or near their peripheries, a stoma-receiving opening (16), a collecting cavity (18) defined between the first and second walls wherein the stoma-receiving opening is fluidly connected to the collecting cavity, a connection member (20) connected to the first wall for attaching the appliance directly or indirectly to a user, a gas vent (8) for venting gas from the collecting cavity to atmosphere, a filter (9) positioned over the gas vent, said filter defining a first discrete area, a third wall (30), wherein the second wall includes a first surface (34) and the third wall includes a second surface (56), wherein the first and second surfaces face each other and are connected at a connection (60), and wherein the connection defines a second discrete area.

Abstract: An ostomy appliance including: first and second walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening; a connection member connected to the first wall for attaching the appliance to a user; a waste collecting chamber defined by the first and second walls for receiving waste and/or gas from the stoma-receiving opening; a further chamber defined by at least third and fourth walls which are connected to each other; a gas opening provided in either or both of the third or fourth walls for permitting waste gases to pass therethrough from the waste collecting chamber; a gas vent for permitting gases in the further chamber to escape to atmosphere; and wherein movement of the first and second walls away from each other, from waste or gases entering the waste collecting chamber, increases or at least maintains the volume of the further chamber.

Abstract: A drainable ostomy appliance including: first and second walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening; a collecting cavity defined between the first and second walls; a connection member connected to the first wall for attaching the appliance to a user or for attaching the appliance to a flange for attaching the appliance to a user; an outlet which extends away from the stoma-receiving opening, the outlet terminating at an opening; and a first stiffening member positioned immediately adjacent the opening on a wall of the outlet facing the user, in use, the first stiffening member extending across the outlet; and a second stiffening member positioned next to the first stiffening member, further away from the outlet than the first stiffening member and on the same wall as the first stiffening member, the second stiffening member also extending across the outlet.

Abstract: A valve for a urostomy appliance including: a housing for connection to the urostomy appliance, the housing having an inlet and an outlet, wherein the housing includes a housing passage extending between the inlet and outlet, and a body which is received in the housing passage and which is rotatable about an axis between an open position, in which liquid is permitted to flow to the outlet, and a closed position, in which liquid is substantially prevented from flowing to the outlet, wherein the body is received in the opening in the housing and has a body passage extending from a body inlet to a body outlet, wherein when the body is in its open position the body outlet at least partially aligns with the housing outlet and permits liquid to pass through the body passage and flow through the housing outlet, and wherein the valve includes a sealing device which extends around a periphery of the body between the body and the housing passage and which extends around the body outlet, such that the sealing device pre

Abstract: An ostomy appliance having first and second walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening, and a waste collecting cavity defined between the first and second walls, wherein the second wall includes viewing portion through which the stoma-receiving opening can be viewed.
