Abstract

Official abstract text for this publication.

Certain embodiments of the present application relate to an adjustable ostomy wafer system including an ostomy wafer and an insert ring 100. The ostomy wafer includes an adjustable layer with an effluent opening through which effluent flows, and the adjustable layer has a body-facing side and a non-body-facing side. The insert ring 100 is capable of providing or increasing convexity of the adjustable layer when the insert ring 100 is pressed against the non-body-facing side of the adjustable layer.

First claim

Opening claim text (preview).

What is claimed is: 1. An adjustable ostomy wafer system comprising: a. an ostomy wafer comprising an adjustable layer, with an effluent opening through which effluent flows, wherein the adjustable layer has a body-facing side and a non-body-facing side; and b. an insert ring capable of providing or increasing convexity of the adjustable layer when the insert ring is pressed against the non-body-facing side of the adjustable layer, wherein the insert ring is capable of providing or increasing convexity of the adjustable layer when translated relative to the ostomy wafer without rotation relative to the ostomy wafer. 2. The adjustable ostomy wafer system of claim 1 , further comprising an external adhesive layer extending beyond an outer edge of the adjustable layer, wherein the external adhesive layer has an adhesive body-facing side. 3. The adjustable ostomy wafer system of claim 1 , wherein the adjustable layer holds the insert ring in place during use to maintain the convexity in the adjustable layer. 4. The adjustable ostomy wafer system of claim 1 , wherein the insert ring comprises a groove that engages a portion of the adjustable layer. 5. The adjustable ostomy wafer system of claim 4 , wherein the groove engages an edge of the adjustable layer located proximal to the effluent opening, thereby securing and maintaining a position of the insert ring in the adjustable layer. 6. The adjustable ostomy wafer system of claim 4 , further comprising a convex insert, wherein the groove engages the convex insert, thereby securing and maintaining a position of the insert ring in the adjustable layer. 7. The adjustable ostomy wafer system of claim 6 , wherein at least a portion of the convex insert that engages the groove is more rigid than the adjustable layer or a portion thereof. 8. The adjustable ostomy wafer system of claim 4 , further comprising at least one locking tab that engages the groove of the insert ring, thereby maintaining a position of the insert ring in the adjustable layer. 9. The adjustable ostomy wafer system of claim 4 , wherein the insert ring comprises a plurality of grooves, and wherein each of the grooves corresponds to a different level of convexity of the adjustable layer. 10. The adjustable ostomy wafer system of claim 1 , wherein the convexity of the adjustable layer is variable between a minimal convexity and a maximal convexity, and wherein the maximal convexity is about one inch. 11. The adjustable ostomy wafer system of claim 1 , further comprising an internal adhesive layer that at least partially covers the body-facing surface of the adjustable layer. 12. The adjustable ostomy wafer system of claim 1 , wherein the adjustable layer provides a barrier or seal against effluent, thereby ensuring effluent flows only through the effluent opening. 13. A method of using the adjustable ostomy wafer system of claim 1 , the method comprising contacting a flush stoma or a retracted stoma with the ostomy wafer. 14. A kit comprising: a. an ostomy wafer comprising an adjustable layer, with an effluent opening through which effluent flows, wherein the adjustable layer has a body-facing side and a non-body-facing side; and b. a plurality of insert rings capable of providing or increasing convexity of the adjustable layer when the insert ring is pressed against the non-body-facing side of the adjustable layer without rotating the insert ring relative to the ostomy wafer; wherein a first insert ring and a second insert ring of the plurality of insert rings differ in an aspect selected from diameter, rigidity, height, and a combination thereof. 15. The kit of claim 14 , wherein at least one insert ring comprises a groove that engages a portion of the adjustable layer. 16. The kit of claim 15 , wherein the first insert ring and the second insert ring each comprise at least one groove. 17. The kit of claim 16 , wherein the first insert ring and the second insert ring comprise a different number of grooves. 18. The kit of claim 14 , further comprising an ostomy pouch, wherein the ostomy pouch is capable of coupling to a coupling component of the ostomy wafer. 19. The kit of claim 18 , wherein the ostomy pouch and the ostomy wafer are provided as separate components before use. 20. The kit of claim 19 , wherein the ostomy pouch and the ostomy wafer are connected before use, but the effluent opening and non-body-facing side of the ostomy wafer is exposed before use. 21. The kit of claim 14 , wherein each of the insert rings is configured to provide or increase the convexity of the adjustable layer in response to manual application of an axial pushing force on the insert ring. 22. The kit of claim 15 , wherein each groove is annular. 23. The adjustable ostomy wafer system of claim 1 , wherein the insert ring is configured to provide or increase the convexity of the adjustable layer in response to manual application of an axial pushing force on the insert ring. 24. The adjustable ostomy wafer system of claim 4 , wherein the groove is annular. 25. The kit of claim 14 , wherein each of the insert rings is separate from the ostomy wafer.
