Abstract

Trimmable conformable wound dressings, kits containing the same and methods of using the same. The wound dressings may protect a treatment site from microbial contamination or other disturbances whilea wound heals or to enable the application and maintenance of vacuum over the treatment site. The wound dressings may include first and second sections of support layer material on opposite sides ofone or more intermediate sections of support layer material. The first and second sections of support layer material meet the intermediate sections of support layer material along peel tab junctions that provide peel tabs.

Description

Background technique [0001] Transparent film dressings are widely used as a protective layer on wounds because they facilitate recovery in moist environments and act as a barrier to contaminated fluids and bacteria. The film is also used as a surgical drapes due to its barrier properties. Membrane dressings are also used in negative pressure wound therapy as drapes to allow application and maintenance of a vacuum, which has been shown to improve wound healing. Dressings and drapes conforming to the above description are available under several trade names such as TEGADERM (3M Company, St. Paul, MN), BIOCLUSIVE (Johnson & Johnson, New Brunswick, NJ), Company (Johnson & Johnson Company, New Brunswick, N.J.)), OP-SITE (T.J.Smith & Nephew, Hull, England) and U IPLEX (Howe Medical, Largo, FL )). [0002] In addition, various specifically shaped transparent film dressings and corresponding delivery systems have been developed for applying dressings to specific body parts or regio...
