Configuring elastic supports
View Patent ↗An ostomy belt has an elastic support membrane with a fibrous surface and an aperture for accessing a stoma. The aperture is formed by the user in a preferred location, and the area around the aperture is stabilized against stretch by applying a patch of relatively inelastic hook material to the fibrous surface about the aperture. An elastic membrane of an adhesive bandage is similarly stabilized about an opening in the bandage, by a hook patch that may have a flap for securing an IV tube.
1. A method of configuring an elastic support membrane having a fibrous surface, the method comprising
forming an aperture through the membrane at a selected location, such that the aperture is surrounded by the fibrous surface; and
securing a stretch stabilizer to the fibrous surface of the membrane, the stretch stabilizer defining an opening therethrough, the opening at least mostly surrounded by a field of touch fastening elements that extend from a surface of the stretch stabilizer and releasably engage with the fibrous surface of the membrane with the stretch stabilizer secured;
wherein with the stretch stabilizer secured, the opening is aligned with the aperture to form an access passage through the membrane and the stretch stabilizer, with
the secured stretch stabilizer impeding stretch of the membrane in the vicinity of the formed aperture while allowing an adjacent region of the membrane to stretch.
2. The method of claim 1 , wherein the elastic support membrane is of a strap configured to couple to itself about living tissue.
3. The method of claim 2 , wherein the strap is in the form of an abdominal belt.
4. The method of claim 1 , wherein the elastic support membrane is of a bandage carrying adhesive, the method comprising adhering the bandage to living tissue at opposite ends of the membrane, thereby holding the membrane against the tissue.
5. The method of claim 1 , wherein the stretch stabilizer comprises a layer of resin forming a surface of the stabilizer and forming, together with the touch fastening elements, a single, contiguous mass of resin.
6. The method of claim 1 , further comprising forming a slit in the membrane running from the aperture to an edge of the membrane.
7. The method of claim 6 , wherein the stretch stabilizer comprises a flap positioned to extend across and close the slit in use.
8. The method of claim 1 , wherein the adjacent region of the membrane surrounds the stretch stabilizer.
9. The method of claim 1 , wherein the touch fastening elements are configured to snag fibers of the fibrous surface so as to allow for a gradual reduction in relative displacement between the fibrous surface and the stabilizer from an outer edge of the field of touch fastening elements toward the opening during stretch of the membrane.
10. The method of claim 1 , wherein the stretch stabilizer comprises a flexible patch.
11. The method of claim 10 , wherein the patch comprises a flexible flap, the method comprising, after securing the stretch stabilizer to the fibrous surface, securing a tube adjacent to the aperture by folding the flap over the tube and securing a distal end of the flap to hold the tube in place.
12. The method of claim 1 , further comprising, prior to forming the aperture, selecting the location at which the aperture is to be formed.
13. The method of claim 1 , wherein the aperture is formed before the stretch stabilizer is secured.
14. The method of claim 1 , wherein the stretch stabilizer is secured over and to a stretched area of the membrane.
