ABSTRACT:
A medical electrode, e.g. for electrocardiography is provided in the form of a pad, one side of which has an electrical terminal. The opposite side, which is to contact the patient's skin, has a removable assembly in which electrically conductive fluid is held in a deformable reservoir, normally a capsule, and maintained out of contact with the pad by an isolating device which yields to allow the fluid to impregnate the pad when the reservoir is pressurized. Then, on removal of the assembly, the pad is ready for use. A preferred form of isolating device has a layer of isolating material which disrupts on the pressurization and a layer of paper which is scored or otherwise arranged to localize the disruption. Using aluminum foil as the isolating material gives a very favorable satisfactory shelf-like.
