DEVICE FOR DELIVERY OF REDUCED PRESSURE TO BODY SURFACES
First Claim
1. A reduced pressure treatment system, comprising:
- a cover structure comprising an outer edge, an upper surface, a lower surface, and at least one opening;
a flowable adhesive layer attached to the lower surface of the cover structure, wherein the flowable adhesive layer has a thickness of at least about 0.2 mm; and
a non-electrically powered, self-generating vacuum source.

Abstract
Disclosed herein is a device which is intended to deliver and maintain reduced pressure to body surfaces for application of reduced pressure wound therapy (RPWT) also known as negative pressure wound therapy (NPWT). During application of this type of therapy, a substantially airtight seal is formed around a section of tissue to be treated. This seal is formed by a dressing which provides fluid communication from a section of tissue to a reduced pressure source. Disclosed herein is a dressing system which is configured to enhance usability and functionality of this dressing. First, the system may be configured to allow full rotation of the fluid communication conduit to the reduced pressure source along the axis substantially normal to the dressing. Second, the system may be configured to include a one-way valve to prevent backflow of any drainage fluids. Third, the system may be configured with transparent windows covered by opaque flaps to allow inspection through the dressing. Fourth, the system may be configured to include an indicator which visually makes clear whether reduced pressure is being applied or not. Fifth, the system is configured to minimize the profile of the dressing system.
