Abstract:
A contactor for establishing electric communication with organic tissue comprising:a cup shaped housing, said housing of rubbery material with a mouth bounded by a rim, the rim for engaging organic tissue, said mouth opening into a main recess of said housing; an electrode within said housing, said electrode comprising a contact plate having a first side within said recess toward said mouth and recessed below said rim, and a second side with integrally connected resilient legs, said electrode contact plate and legs of one-piece molded plastics and coated with an outer layer of silver/silver chloride so as to have an electrically conductive exterior surface; said resilient legs residing within a leg well of said housing and clamping against a venturi tube having means for creating a suction at a suction port thereof upon passage of pressurized gas through said venturi tube, said venturi tube arranged with the suction port thereof positioned in communication with the main recess of said housing, whereby suction at the suction port can create low pressure in the housing recess, said venturi tube mounted to said housing with an end of the venturi tube positioned for allowing connection of the venturi tube end to a pressurized gas supply line and an output electrical wire, said venturi tube including gold plating so as to be electrically conductive from at least the engagement of said resilient legs of said electrode to the exposed end of the venturi tube so as to serve as an electrical conductor between said electrode and an output electrical wire when the wire is electrically connected to the venturi tube end.
