Multi-layered dressing
First Claim
1. An adhesive composite comprisinga) a polymeric backing layer that is liquid and bacteria impermeable, b) a high moisture vapor transmission layer comprising a gel-adhesive mixture composition that comprises a pressure-sensitive adhesive, a hydrocolloid, and a liquid swelling agent, and c) a skin contacting adhesive layer, and wherein said high moisture vapor transmission layer is selected from an adhesive material having a Standardized Transmission Rate of at least 900 g/m2/24hrs/37°
- C./100-20% RH, and the skin contacting adhesive layer is selected from an adhesive material having an adhesion to skin strength of a least 15 g/in., provided that the material of layer b) is not the same as the material of layer c) and that the overall adhesive composite exhibits a moisture vapor transmission rate of at least about 1200 g/m2/24 hrs/37°
