Ostomy pouches

Apparatus comprising a vent for an ostomy pouch, the vent comprising aperture means, a flow restricting layer upstream of the aperture means, and adhesive sticker means which can be positioned to selectively block one or more areas of the aperture means.

An ostomy pouch comprising a first wall, provided with a comfort layer and with a flatus vent, the pouch further comprising adhesive sticker means attached, or attachable, to the vent to facilitate the control of the flow of flatus through the vent.

An ostomy pouch comprising a first wall of substantially liquid impermeable and gas impermeable plastics material, an aperture provided in the first wall to allow venting of flatus therethrough, a comfort layer provided outside the first wall, and a filter cover layer outside the comfort layer and secured to the first wall through the comfort layer, the cover layer and the portion of the first wall underlying the cover layer defining a housing in which is received a filter for processing flatus vented through the aperture.

An adhesive wafer for directly or indirectly securing an ostomy pouch to a person's skin, wherein the wafer, or a cover layer provided on the wafer, is provided with guidelines for enabling a person to cut the wafer to a desired aperture size, the guidelines including at least one generally circular guideline, and at least one generally non-circular guideline.

An ostomy pouch comprising a pouch envelope and an adhesive wafer for directly or indirectly securing the pouch envelope to a person's skin, wherein the wafer, or a cover layer provided on the wafer, is provided with guidelines for enabling a person to cut the wafer to a desired aperture size, the guidelines including at least one generally circular guideline, and at least one generally non-circular guideline, and the adhesive wafer being secured to the envelope around a closed loop line of attachment, the line of attachment having a shape which is non-circular and non-race-track.

A body-side device for attachment to an ostomy pouch, the body-side device comprising an adhesive wafer for directly or indirectly securing the ostomy pouch to a person's skin, and a coupling portion for releasable fastening to the pouch, wherein the wafer, or a cover layer provided on the wafer, is provided with guidelines for enabling a person to cut the wafer to a desired aperture size, the guidelines including at least one generally circular guideline, and at least one generally non-circular guideline, and wherein the wafer is secured to the coupling portion around a closed loop line of attachment, the line of attachment having a shape which is non-circular and non-race-track.

Use of adhesive sticker means to control variably the vent flow rate through a filtered vent for an ostomy pouch, the vent having a plurality of outlets, and the sticker means being positionable to selectively expose or cover one or more of the plurality of outlets, to thereby regulate the gas flow rate according to the outlets exposed.

A method of controlling variably the flow rate through a filtered vent of an ostomy pouch, the method comprising positioning sticker means to selectively expose or block one or more of a plurality of outlets of the vent, to regulate the gas flow rate according to the outlets exposed.
