Easy to remove adhesive sheets

摘要

An adhesive sheet comprising a backing layer (1) with a layer of adhesive (2) applied to a first side of the backing layer and a reservoir or conduit (4) for a liquid provided on the first side of the backing layer. The conduit supplies liquid, such as saline, to the adhesive layer, reducing its adherency and thereby assisting removal of the adhesive sheet after use. The conduit maybe a liquid permeable tube with a standard syringe connection (8) to allow filling with liquid. Alternatively it may be prefilled with a release pull strip to secrete the liquid. The backing layer maybe a polyurethane or polyolefin sheet, impermeable to liquids and microorganisms. Optionally a layer of absorbent material (3) may be incorporated centrally.
