Abstract

A body electrode holder includes a holding member to be disposed on an outer surface of a living body, and a plurality of perforations formed in predetermined positions of the holding member, through which perforations a plurality of body electrodes pass respectively, the holding member being formed of a sheet material. The predetermined positions correspond to portions of the living body in which portions bioelectricity is to be measured. The body electrode holder makes it possible to a plurality of body electrodes at once and easily to predetermined positions without requiring special technic or knowledge regarding positions to attach the body electrodes.

Claims

1. A body electrode holding device comprising:

a first electrode holder and a second electrode holder to be disposed on an outer surface of a living body, said first and second electrode holders being formed of a sheet material or non-woven fabric respectively, said second electrode holder being divided into two portions, said two portions capable of being adjusted in the amount in which said two portions overlap each other by increasing or decreasing the amount of overlap to permit adjustment of longitudinal length of said second electrode holder; and

a plurality of perforations formed in predetermined positions of said first and second electrode holders, through which performations a plurality of body electrodes pass respectively,

said predetermined positions corresponding to portions of said living body in which portions bioelectricity is to be measured.

2. A body electrode holding device according to claim 1, wherein said first electrode holder attaches a first body electrode, said second electrode holder attaches a second body electrode, said first electrode holder is further provided with a first lead wire holder for fixing to said first electrode holder a first lead wire connected to said first body electrode, and said second electrode holder is further provided with a second lead wire holder for fixing to said second electrode holder a second lead wire connected to said second body electrode.

3. A body electrode holding device according to claim 2, wherein said first lead wire is formed at a first portion thereof integrally with said first electrode holder, said first portion being arranged on said first electrode holder, and said second lead wire is formed at a second portion thereof integrally with said second electrode holder, said second portion being arranged on said second electrode holder.

4. A body electrode holding device according to claim 1, wherein said second electrode holder is provided with recesses disposed transversely at portions of said second electrode holder so as to enable dividing said second electrode holder into a plurality of portions along said recesses, said portions being adjacent to regions where each of said body electrodes is to be arranged.

5. A body electrode holding device according to claim 1, wherein said second electrode holder is divided into two portions so that one of said two portions can be superimposed on the other of said two portions through an adhesive to adjust a longitudinal length of said second electrode holder.

6. A body electrode holding device according to claim 5, wherein said one of said two portions is provided with a graduation so as to define said longitudinal length of said second electrode holder.

7. A body electrode holding device according to claim 1, wherein said two portions are formed to be bonded to each other.

8. A body electrode holding device according to claim 7, wherein said second electrode holder is provided with a graduation so as to define a size of said two portions.

9. A body electrode holding device according to claim 1, wherein each of said body electrodes comprises:

a living body contacting portion to be contacted with said outer surface for taking out said bioelectricity from said living body, said living body contacting portion being of a disk-like shape;

an electrode portion received in said living body contacting portion for detecting said taken-out bioelectricity;

an annular fixing portion concentrically disposed around a periphery of said living body contacting portion for fixing said electrode portion and said living body contacting portion to said living body;

a circular sheet connected to an annular end face of said living body contacting portion and an annular end face of said annular fixing portion for securing said electrode portion;

a snap portion connected to said electrode portion in such a manner as to penetrate said circular sheet to thereby protrude in a direction opposite to said electrode portion with respect to said circular sheet, and having an outer diameter capable of being inserted into each of said perforations; and

an electrode connector adapted to nip said inserted snap portion, and connected to a lead wire for sending said detected bioelectricity to an inspection equipment.

10. A body electrode holding device comprising:

a first electrode holder, a second electrode holder and a third electrode holder to be disposed on an outer surface of a living body, said first, second and third electrode holders being formed of a sheet material or non-woven fabric respectively, said third electrode holder connected at one end thereof to an intermediate portion of said first electrode holder and connected at the other end thereof to an intermediate portion of said second electrode holder; and

a plurality of body electrodes

a plurality of perforations formed in predetermined positions of said first, second and third electrode holders, through which perforations said plurality of body electrodes pass respectively,

said predetermined positions corresponding to portions of said living body in which portions bioelectricity is to be measured.

11. A body electrode holding device according to claim 10, wherein said first electrode holder attaches a first body electrode, said second electrode holder attaches a second body electrode, said first electrode holder is further provided with a first lead wire holder for fixing to said first electrode holder a first lead wire connected to said first body electrode, and said second electrode holder is further provided with a second lead wire holder for fixing to said second electrode holder a second lead wire connected to said second body electrode.

12. A body electrode holding device according to claim 11, wherein said first lead wire is formed at a first portion thereof integrally with said first electrode holder, said first portion being arranged on said first electrode holder, and said second lead wire is formed at a second portion thereof integrally with said second electrode holder, said second portion being arranged on said second electrode holder.

13. A body electrode holding device according to claim 10, wherein said second and third electrode holders are respectively provided with second and third length adjusting portions for adjusting longitudinal lengths of the respective second and third electrode holders.

14. A body electrode holding device according to claim 13, wherein each of said second and third electrode holders are bent so that they can adjust a longitudinal length.

15. A body electrode holding device according to claim 14, wherein each of said second and third electrode holders is provided with a graduation so as to define a size of each of said second and third length adjusting portions.

16. A body electrode holding device according to claim 10, wherein said second electrode holder is provided with recesses disposed transversely at portions of said second electrode holder so as to enable dividing said second electrode holder into a plurality of portions along said recesses, said portions being adjacent to regions where each of said electrodes is to be arranged, and said third electrode holder is provided with two recesses disposed transversely at portions of said third electrode holder so as to enable disconnecting along said two recesses said third electrode holder from said first and second electrode holders, said portions being adjacent to said first and second electrode holders.

17. A body electrode holding device according to claim 10, wherein said second electrode holder is divided into two portions so that one of said two portions can be superimposed on the other of said two portions through an adhesive to adjust a longitudinal length of said second electrode holder.
