Abstract
A protective device that provides protection against infection by accidental skin puncturing. The device includes a flexible expanse, at least a portion of which has a multi-layer construction that includes (i) inner and outer, flexible, electrically conductive layers, and (ii) a flexible insulative sheet separating said conductive layers. A voltage applied across the two layers is effective to heat the tip of a needle, scalpel, or the like, when such pierces the cover, to a temperature effective to destroy at least a portion of the infectious agent.
