Abstract
The present invention is directed toward an ostomy appliance having a vent for filtering gasses exiting the ostomy appliance. The 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; a multi-layer filter positioned adjacent and covering the aperture on an exterior surface of the respective first and/or second wall, wherein a layer of the filter is hydrophobic and wherein said hydrophobic layer is positioned directly adjacent the respective first and/or second wall so as to directly and completely cover the aperture, wherein the hydrophobic layer has a first side and a second side and wherein the first side is connected directly to the respective first and/or second wall, said connection holding the multi-layer filter relative to the respective first and/or second wall; wherein the filter includes a de-odorising layer positioned adjacent the hydrophobic layer; wherein the filter includes a gas and liquid impermeable layer positioned adjacent the de-odorising layer; and wherein the gas and liquid impermeable layer is configured to ensure that, in use, all gas entering the filter passes through the de-odorising layer in a direction substantially parallel to the respective first and/or second wall. The arrangement of the hydrophobic layer, the de-odorizing layer, and the liquid impermeable layer allow for a simple construction of the filter while protecting the de-odorizing layer from liquid contaminants.
Claims (11)
1. An ostomy appliance comprising: first and second walls connected to each other at or near their 5 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; 10 a multi-layer filter positioned adjacent and covering the aperture on an exterior surface of the respective first and/or second wall, wherein a layer of the filter is hydrophobic and wherein said hydrophobic layer is positioned directly adjacent the respective first and/or second wall so as to directly and completely cover the aperture, 15 wherein the hydrophobic layer has a first side and a second side and wherein the first side is connected directly to the respective first and/or second wall, said connection holding the multi-layer filter relative to the respective first and/or second wall; wherein the filter includes a de-odorising layer positioned adjacent the 20 hydrophobic layer; wherein the filter includes a gas and liquid impermeable layer positioned adjacent the de-odorising layer; and wherein the gas and liquid impermeable layer is configured to ensure that, in use, all gas entering the filter passes through the de-odorising layer in 25 a direction substantially parallel to the respective first and/or second wall.
2. The ostomy appliance according to claim 1 wherein the hydrophobic layer is Polytetrafluoroethylene (PTFE).
3. The ostomy appliance according to claim 1 or claim 2 wherein the first side of the hydrophobic layer is connected directly to the respective first and/or second wall by an adhesive. 5
4. The ostomy appliance according to claim 3 wherein the first side of the hydrophobic layer is connected directly to the first and/or second wall by a hot melt adhesive.
5. The ostomy appliance according to claim 3 wherein the first side of the 10 hydrophobic layer is connected directly to the first and/or second wall by double-sided tape.
6. The ostomy appliance according to any one of claims 1 to 5 wherein the de-odorising layer is carbon based.
7. The ostomy appliance according to any one of claims 1 to 6 wherein the layers of the filter are arranged in the order of hydrophobic layer, de-odorising layer and gas and liquid impermeable layer. 20
8. The ostomy appliance according to claim 7 wherein the de-odorising layer is positioned directly adjacent the hydrophobic layer and wherein the gas and liquid impermeable layer is positioned directly adjacent the de-odorising layer. 25
9. The ostomy appliance according to any one of claims 1 to 8 wherein waste gas travels through the aperture in a direction substantially perpendicular to the first and/or second wall, in use.
10. The ostomy appliance according to any one of claims 1 to 9 wherein 30 waste gas travels through the hydrophobic layer in a direction substantially perpendicular to the first and/or second wall, in use.
11. The ostomy appliance according to claim 1, substantially as herein described with reference to any embodiment disclosed.
