Abstract: An improved electrode assembly for use in providing a stimulating current to a living body is disclosed. The assembly comprises a plurality of electrode modules electrically connected together in series with flexible electrical conductors, preferably in the form of a wire, so that, the modules and conductors form an integral assembly and so that in accordance with the method of the present invention the modules each can be selectively oriented and positioned on the skin with respect to one another enabling the assembly to follow the direction of an incision. In the preferred form the modules of the assembly are initially mechanically connected together with a single sheet having perforations so that the sheet can be torn along the perforations when separating the modules from one another. The number of modules applied to the skin can easily be reduced from the plurality by disconnecting the wire at the appropriate location so as to reduce the number of modules to the desired number.

Abstract: This disclosure is concerned with a two-piece, similar metal-plated plastic mating stud and eyelet electrode structure for electrocardiograph or similar physiological or bioelectric measurements, embodying internal resilient ring and groove sealing members for preventing corrosive electrolytic gel interactions with the interfaces of the electrode assembly that can otherwise produce erratic electrical performance.

Abstract: An improved electrical connector assembly (for transmitting biopotential signals) comprises a main terminal connector associated with a master cable connectable to the signal processing apparatus and at least one plug associated with a single cable connectable to an biopotential electrode for sensing the biopotential signal of increase. The connector comprises a cavity defining a plurality of contiguous passageways each structured so as to receive the plug in only one direction to provide proper polarization. The design of the plug and the passageways, a color coding provided on the housing and the plug, the provision of an automatic interlocking mechanism allowing each plug to be inserted in any passageway and automatically locked in place, provides for easy, reliable and quick connections to be made. The preferred connector is designed to be easily cleaned such as by immersing it in a cleaning fluid, and the connecting pins are provided in a protective manner in the connector.

Abstract: An improved carrier release sheet is described for use with biopotential skin electrodes of the type including a stud, a pad preloaded with an electrically conductive material and in electrical contact with the stud, a base sheet having an aperture and secured to said stud so that the pad is exposed through the aperture to one side of the base sheet having an adhesive coating. The carrier release sheet includes a cylindrical cavity of an improved configuration for receiving the preloaded pad of the electrode in a noncontacting relationship and a tab integrally formed with the remainder of the carrier release sheet so as to enable quick and easy release of the carrier sheet from the adhesive coating.
