Abstract:
A hydration assembly for use in hydrating a hydratable matrix element of an iontophoresis bioelectrode, said hydration assembly comprising:a hydrating liquid;hydrating liquid isolation means for maintaining said hydrating liquid in isolation from said hydratable matrix element until it is desired to hydrate the hydratable matrix element, said hydrating liquid isolation means comprising a first portion reversibly sealed to a strip element to define a liquid-storage component therebetween; andhydration activation means for effecting progressive release of said hydrating liquid from said liquid-storage component, said hydration activation means comprising a strip extension, said strip extension having a first end and a second end, said first end being continuous with said strip element and said strip extension being folded over at said first end such that said strip extension is folded upon, adjacent to, and aligned with said strip element over substantially the entire length of said strip element, and said second end having an accessible tab member continuous with said strip extension;wherein operation of said tab member causes progressive movement of said strip extension away from said liquid-storage component, progressive inverting of said strip element upon itself, and progressive reversing of the seal between the strip element and the first portion.
