Abstract

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.

Claims

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, the upward projecting head disposed on the flexible flange;

a flange disposed at the transition between the head portion and flexible flange; and

c) an electrode material;

wherein, the flange is arranged to provide a stop for creating a pre-defined deflection of the flexible flange when the flat top part along with the electrode material is pressed against the flexible flange.

2. The electrode according to claim 1, wherein each of distal ends of the upward inclination of the flexible flange is at a first pre-determined height from base of the flexible flange, the flange is at a second pre-determined height from the base of the flexible flange, wherein the first pre-determined height is greater than the second pre-determined height.

3. The electrode according to claim 2, the pre-defined deflection is created by the displacement of each of the distal ends of the flexible flange from the first pre-determined height to the second pre-determined height.

4. The electrode according to claim 1, wherein the flat top part is magnetic/magnetizable for connecting with a bio-medical device.

5. The electrode according to claim 1, characterized in that the flange is designed to press with a force ranging between about 5 N and about 20 N.

6. The electrode according to claim 1, characterized in that the flange (22) is cone-shaped.

7. The electrode according to claim 1, characterized in that the bottom part is electrically conductive.

8. The electrode according to claim 1, wherein the flat top part is electrically conductive.

9. The electrode according to claim 1, characterized in that the head portion of the bottom part is fixed in the aperture of the top part by a press fit or a snap connection.

10. The electrode according to claim 1, characterized in that the edges of the aperture and/or of the head portion are rounded.

11. The electrode according to claim 1 is at least one of a TENS electrode, a ECG electrode, a EEG electrode, an electromyography electrode, an electrical muscle stimulation electrode, a neuromuscular stimulation electrode, and a functional electrical stimulation electrode.

12. The electrode according to claim 1, where in the electrode material is one or more electrode sheets.

13. The electrode according to claim 12,

characterized in that the one or more electrode sheets has a hole through which the head portion of the bottom part extends.
