Abstract
A skin abrader for a biomedical electrode is disclosed wherein the abrader has a geometrically structured surface abrasive selected to provide sufficient abrasive effect to easily remove a portion of the stratum corneum of mammalian skin with minimal skin irritation, in order to reduce skin impedance encountered during diagnosis or monitoring of a mammalian patient.
Claims20
A skin abrader for a biomedical electrode, comprising:
- polymeric material having a geometrically structured surface abrasive, wherein the polymeric material is free of abrasive particles.
A method of making a skin abrader for a biomedical electrode, comprising:
- (a) forming a film of polymeric material having a geometrically structured surface abrasive, wherein the geometrically structured surface abrasive has a pattern adapted to remove a portion of stratum corneum of mammalian skin and further wherein the polymeric material is free of abrasive particles;
- (b) separating a portion of the film to form an abrader strip;
- and
- (c) placing the abrader strip in contact with a dispenser.
A skin abrader for a biomedical electrode, comprising polymeric material having a geometrically structured surface abrasive, wherein the polymeric material is free of abrasive particles, and further wherein the geometrically structured surface abrasive has a pattern with a pitch between a height and a depth in the topography that is variable, and still further wherein the vertical dimension between the height and the depth ranges from about 25 .mu.m and 1524 .mu.m.
An article comprising:
- a biomedical electrode;
- and
- a skin abrader comprising polymeric material having a geometrically structured surface abrasive, wherein the polymeric material is free of abrasive particles.
