Medical electrode with reusable conductor
First Claim
1. A medical electrode assembly comprising:
- a reusable lead wire assembly; and
a disposable electrode pad havingan electrolyte gel matrix,socket means overlying said gel matrix including means for connection of said lead wire assembly to said matrix,a flexible clamp plate overlying said socket means, said clamp plate covering said connection means,means releasably securing said clamp plate to said socket means so that said clamp plate may be peeled away from said socket means sufficiently to uncover said connection means, andmeans for retaining said clamp plate with the other parts of said pad when it is peeled away from said plate means.

Abstract
A disposable electrode pad is provided with a socket for a reusable electrode conductor attached to a lead wire. The pad includes a socket plate having a release coated top surface and overlying a frame having a bore filled with a gel matrix. The pad further includes a flexible clamp plate, part of which is strongly adhered to the frame and the rest of which is adhered to the release coated surface of the socket plate. The socket plate is provided with a bore used as a socket for a reusable, low profile electrode conductor which is fixedly attached to a lead wire having a jack for connection to external monitoring equipment. In use, the electrode pad is applied to the skin of a subject, the releasable part of the clamp plate is peeled away from the socket plate, the electrode conductor is inserted into the bore of the socket plate, and the clamp plate re-adhered to the socket plate in covering relation to the electrode conductor and the end of the lead wire attached thereto. Accordingly, the end of the lead wire and the electrode conductor are securely held in place relative to the gel matrix. Embodiments for both monitoring and stimulation purposes and alternative electrode conductor/lead wire embodiments are disclosed.
