Abstract

Ostomy appliance components for cleaning and related maintenance of a surgical stoma. Components take the form of attachments, inserted elements, and/or separate parts in contact with ostomy ports, wafers, and/or other connecting components.

Claims

1. A restraint for a collapsed waste collection pouch of an ostomy appliance, comprising:

a body; and

one element of

at least one pair comprising a receiving aperture and an inserting projection,

the projection sized to insert into the aperture and form a fitting attachment,

the other element of the at least one pair being upon the ostomy appliance;

such that

the attached body is positioned to restrain the collapsed pouch from expanding under pressure from within the ostomy appliance to the volume which the unrestrained pouch is rated to contain, wherein the one element is disposed upon the body, and wherein the receiving aperture is a depression on a surface of the body if the receiving aperture is disposed upon the body, or is a depression on a surface of the ostomy appliance if the receiving aperture is disposed upon the ostomy appliance; and

the strength of the fitting attachment is set so that it breaks when pressed by a pressure from within the ostomy appliance which exceeds a predetermined threshold.

2. The restraint according to claim 1, wherein the restraint is fixedly attached to the ostomy appliance through a flexible member.

3. The restraint according to claim 2, wherein the flexible member is a hinge.

4. The restraint according to claim 1, wherein the elements of the at least one pair are disposed on facing surfaces of the body and the ostomy appliance.

5. The restraint according to claim 4, wherein at least one element of the at least one pair comprising a receiving aperture and inserting projection is of variable size, at least across a profile, such that the relative size of receiving aperture and projection at the place of attachment is selected by the relative positioning of the pair elements.

6. The restraint according to claim 5, wherein the attachment-breaking pressure is different depending on the relative attached positioning of the at least one pair comprising a receiving aperture and inserting projection.

7. The restraint according to claim 1, wherein:

at least two regions of fitting attachment have attachment broken, each above a different pressure threshold;

one threshold being higher than the other;

attachment loss at the lower threshold comprising a loss of resistance to the escape of stomal gasses from the ostomy appliance; and

attachment loss at the higher threshold comprising loss of restraint on the expansion of the pouch.

8. The restraint according to claim 1, wherein said body is adapted to distend under pressure from said pouch, the distention of said body serving as a pressure indicator for a user of said restraint.
