Abstract

A cutaneous medical device having a main part containing an electrical energy source that can generate an electric current and electronic components that form part of an electric circuit; and at least one removable cutaneous electrode comprising an electric plug. The electrode is intended to be in electric contact with a user. The electrode also includes at least one base which is positioned on a first face of the main part and can be electrically connected to the at least one removable cutaneous electrode.

First claim

The invention claimed is:

1. A cutaneous medical device, comprising:
a main part containing:
an electricity source configured to generate an electric current, and
electronic components at least partially forming an electric circuit;

at least one removable cutaneous electrode including a plug, the at least one removable cutaneous electrode being configured to be in electrical contact with a user; and
at least one base positioned on a first face of the main part and capable of being electrically connected with the at least one removable cutaneous electrode,
wherein the at least one base comprises conductive parts and the plug comprises means for controlling the passage of the current between the conductive parts, wherein the conductive parts are at least in part housed by a common conductive cup, and wherein the conductive parts and the control means form an electric switch having a recognition function for the removable cutaneous electrode by electrically connecting the conductive parts by deforming the conductive cup.

2. The device of claim 1 , wherein the at least one base includes at least one part having an electrical function and the plug includes a cylindrical part having an electrical function, the electrical connection between the at least one base and the plug being provided by the electrical contact between the at least one part having the electrical function and the cylindrical part.

3. The device of claim 2 , wherein an annular part has an electrical function.

4. The device of claim 2 , wherein the at least one base comprises three parts arranged in a circle, and wherein the three parts have an electrical function.

5. The device of claim 4 , wherein the three parts of the at least one base are individually mounted on their corresponding springs.

6. The device of claim 1 , wherein the conductive parts of the at least one base comprise two assemblies that are fixed and electrically isolated from one another.

7. The device of claim 6 , wherein the plug of the at least one removable electrode includes a protuberance having a height such that the protuberance is able to come into contact with both fixed assemblies.

8. The device of claim 6 , wherein the plug of the at least one removable electrode includes a protuberance having a height such that it does not come into contact with the two fixed assemblies when it is inserted into a cavity that houses the two fixed assemblies.

9. The device of claim 6 , wherein the conductive parts of the base also comprise a deformable part placed above the two assemblies.

10. The device of claim 8 , wherein the plug of the at least one removable electrode includes a protuberance having a height such that the protuberance is able to deform the part when it is inserted into the cavity.

11. The device of claim 8 , wherein the plug of the at least one removable electrode includes a protuberance having a height such that no pressure is exerted by the protuberance on the part when it is inserted into the cavity.

12. The device of claim 1 , comprising at least two bases and at least two removable cutaneous electrodes.

13. The device of claim 1 , wherein the main part includes, on a second face, opposite the first, another cutaneous electrode intended to establish electrical contact with the user.

14. The device of claim 1 , wherein the plug and the base are magnetic.

15. The device of claim 1 , comprising four rigid zones and three flexible regions between two adjacent rigid zones.

16. The device of claim 1 , comprising three rigid zones and two flexible regions between two adjacent rigid zones.
