Bio-medical electrode

摘要

The invention relates to a bio-medical electrode (100). In a preferred embodiment, an electrode interface comprises a top part (10) with an aperture and a bottom part (20). The bottom part (20) has a head portion designed for a fixation in said aperture and a flexible flange that clamps electrode sheets (31,32) in the connected state of the electrode interface such that the contact force between top and bottom parts is approximately constant during lifetime of the electrode interface. The top part (10) may preferably have the shape of a disk of magnetic or magnetizable material. The bottom part (20) may preferably be made from a conductive plastic such as ABS. The electrode interface may particularly be used in a TENS device.

主权项

1. A bio-medical electrode comprising:
a) a flat top part having an aperture; b) a bottom part having:
a flexible flange having an upward inclination;an upward projecting head portion that can be fixed in the aperture, wherein the upward projecting head portion comprises a central dome head disposed on the flexible flange;a stop flange disposed on the flexible flange at a transition between the upward projecting head portion and the flexible flange; and c) an electrode material; wherein the stop flange is arranged to provide (i) a mechanical stop and (ii) a displacement in height for creating a pre-defined deflection of the flexible flange to provide a desired upward contact force when the flat top part along with the electrode material is pressed against the flexible flange and stopped via the stop flange, with the upward projecting head portion fixed in the aperture of the flat top part.
