Fluid self-sealing bioelectrode
First Claim
1. A self-sealing bioelectrode for use with electrode fluids including:
- (a) a sheet-like base member having a base opening therethrough, and adapted at a bottom surface thereof for conforming contact at a skin surface;
(b) a receptacle having an opening which is attached at said base member to define a fluid channel through said base opening to the interior of said receptacle;
(c) an injection channel means communicating between the exterior and interior of said receptacle for filling said receptacle with fluid when affixed at said skin surface, said channel means having restricted access means for passing said fluid into said receptacle while precluding subsequent introduction of other fluids therethrough;
(d) a conductive electrode plate disposed within said receptacle interior at such location so as to be remote from said base opening when said electrode is filled with fluid; and
(e) means for coupling said electrode plate to an electric circuit.

Abstract
A dry-state bioelectrode having a self-sealing receptacle for receiving electrolyte and/or medicament fluid contents. The receptacle is attached at its opening to a sheet-like flexible base member having an opening in common with the receptacle opening, the bottom of the base member being adapted for fixation at a skin surface. A portion of the skin surface is exposed to the fluid contents of the receptacle through the common opening. An injection site communicates through the wall of the receptacle and provides controlled access for filling. Upon completion of filling, the receptacle self seals, retaining the fluid contents therein for application of iontophoresis treatment or other procedures requiring use of a potential gradient. An electrode plate is supported at an interior surface of the receptacle for supplying the desired electric potential.
