Abstract
Abstract A male electrode assembly fashioned with a body contacting adhesive coated web for attachment to a body includes a pair of relatively movable parts defining a reservoir for a conductive paste or jelly which is dispensed at the body-contacting side of the electrode in response to relative movement of the parts. Specific embodiments include a push plunger, with or without ribs, a threaded plunger, a bayonet locking plunger, and a simple female structure. Membranes protect the paste against effects of atmosphere, when required.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
195 words
A multi part skin contacting body electrode assembly containing an electrically conductive fluid and adapted to dispense the fluid against the surface of the skin to which it is operatively attached in use, said assembly comprising: a main portion of electrically conductive material having a central opening therethrough and a skin contacting area at one end of said central opening; means for securing the assembly to the body of the user; an electrically conductive connector portion disposed in an initial position within said central opening at the end thereof opposite to said skin contacting area, said main and connector portion adapted to permit movement of said connector portion in said central opening toward said skin contacting area, said main portion and said connector portion mutually configured so as to provide a chamber for fluid therebetween with said connector portion in said initial position, said chamber becoming smaller as a consequence of said connector portion being moved toward said skin contacting area; and an electrically conductive fluid material disposed in said chamber and adapted to be dispersed from said one end of said central opening when said connector portion is moved toward said skin contacting area.
Claim 2
Dependent Claim
195 words
A multi part skin contacting body electrode assembly containing an electrically conductive fluid and adapted to dispense the fluid against the surface of the skin to which it is operatively attached in use, said assembly comprising: a main portion of electrically conductive material having a central opening therethrough and a skin contacting area at one end of said central opening; means for securing the assembly to the body of the user; an electrically conductive connector portion disposed in an initial position within said central opening at the end thereof opposite to said skin contacting area, said main and connector portion adapted to permit movement of said connector portion in said central opening toward said skin contacting area, said main portion and said connector portion mutually configured so as to provide a chamber for fluid therebetween with said connector portion in said initial position, said chamber becoming smaller as a consequence of said connector portion being moved toward said skin contacting area; and an electrically conductive fluid material disposed in said chamber and adapted to be dispersed from said one end of said central opening when said connector portion is moved toward said skin contacting area.
Claim 3
Dependent Claim
49 words
The electrode assembly according to claim 1 additionally comprising: a membrane disposed at the skin contacting area end of said central opening to isolate said conductive fluid from the atmosphere, said membrane comprising a peeloff layer adapted to be removed prior to operatively contacting said assembly to the skin.
Claim 4
Dependent Claim
97 words
The electrode assembly according to claim 1 wherein said connector portion includes a cavity therein, said cavity opening toward said skin contacting area end, and wherein said conducting fluid is disposed within said cavity; and further comprising; a membrane disposed across said cavity opening of said connector portion and sealing off said cavity to isolate said conducting fluid from the atmosphere; and means disposed in said main portion in the skin contacting area end of said central opening for piercing said membrane as a consequence of relative motion of said connector portion toward said skin contacting area.
