DERMAL SUBSTANCE COLLECTION DEVICE

摘要

DERMAL SUBSTANCE COLLECTION DEVICE A dermal substance collection device (DSCD) is described which provides means for the non-invasive, instantaneous and continous monitoring of chemical substances which are present in a detectable amount in either or both interstitial fluid or sweat or which are on or in the skin. The transdermal substance collection device of this invention is comprised of three essential components: (1) a substance binding reservoir, wettable by (2) a liquid transfer medium which allows for liquid bridge transfer of a soluble substance from the skin surface to the binding reservoir by virtue of its wettability by the liquid, and (3) an occlusive cover.
