Abstract
The present subject matter relates to medical devices for ostomy applications, specifically a floating ring design for securing robust attachment between the flange surrounding a stoma on a patient's body and an ostomy bag. Existing ostomy appliance designs present significant drawbacks related to routine, high replacement cost and poor performance, the latter resulting in anxiety, grief over fear of stool leakage due to rapid, sudden and/or unexpected detachment or mechanical compromise of ostomy appliance components. This further includes discomfort due to the mechanical stresses placed on the subject's body.
Claims15
A floating ring adapted for use with an ostomy appliance, the ostomy appliance comprising:
- a flange comprising a flange ring;
- and
- an ostomy bag comprising a pouch ring, wherein the floating ring is adapted for positioning between an annular surface of the flange ring and the annular surface of the pouch ring, wherein the flange ring and pouch ring each comprise interlocking regions capable of directly interlocking the flange ring and the pouch ring to each other through an inner diameter of the floating ring,
- wherein the inner diameter of the floating ring, ID, is 5.0 to 9.0 cm, including the ranges of 5-6, 6-7, and 8-9 cm, and wherein the thickness, T, is 0.7 to 2 mm of an entirety of the floating ring, wherein an outer diameter of the floating ring does not extend beyond the surface area of the flange, and wherein the floating ring is entirely planar and non-concave, and wherein the floating ring is made of material with a Young's modulus of about 170 to 210 gigaPascals.
