Biomedical electrode with limb band
First Claim
1. A biomedical electrode for use on a limb of a patient comprising, a composite electrode pad having upper and lower sides, the composite electrode pad including an electrically conductive member having means for connection to an external apparatus, and a layer of electrically conductive solid gel adhesive electrically contacting the conductive member and providing a skin contacting adhesive surface at the lower side of the electrode pad, a limb band including an elongated conformable first band of non-woven spunlaced fabric having inner and outer sides, the first band including first and second end portions and an elongated intermediate portion and a length sufficient to encircle a limb of a patient and have the second end portion overlap the first end portion, adhesive means securing the inner side of the first end portion of the first band to the upper side of the electrode pad, an elongated dimensionally stable second band of non-woven spunbonded fabric, adhesive means securing one side of the second band to the inner side of the first band along the intermediate portion of the latter to inhibit stretching of the intermediate portion of the first band during use, and pressure sensitive adhesive means on the inner side of the second end portion of the first band for attaching the second end portion to the outer side of the first band adjacent the first end portion.

Abstract
A biomedical electrode with limb band for use on a limb of a patient comprising a composite electrode pad having an electrically conductive member with means for connection to an external sensoring and monitoring apparatus, and a layer of electrically conductive solid gel adhesive contacting the conductive member and providing a skin contacting adhesive surface for attaching the electrode pad to the skin of a patient. A composite limb band includes an outer band formed of non-woven spunlaced polyester fibers and an inner band formed of non-woven spunbonded polyester filaments adhesively secured to an intermediate portion of the outer bank along the inner side thereof. A first end portion of the outer band is adhesively attached to the outer face of the composite electrode pad. The composite limb band has a length to encircle the limb of a patient, and a pressure sensitive adhesive is provided on the inner face of a second end portion of the outer band for adhesively attaching the second end portion onto the outer side of the composite band.
