Abstract

A storage case with a biomedical electrode pad for storing a biological signal processing circuit unit for processing an biological electrical signal which has been detected by the biomedical electrode pad, wherein a case body thereof has a storage area for the biological signal processing circuit unit, the storage area being provided in an openable and closable manner, and the biological signal processing circuit unit is detachable with respect to the storage area.

First claim

The invention claimed is:

1. A storage case with a biomedical electrode pad attached, the biomedical electrode pad being configured to be attached to a skin of a living body and used to detect a biological electrical signal from the skin, the storage case with the biomedical electrode pad being configured to watertightly and detachably store a biological signal processing circuit unit inside, the biological signal processing circuit unit having a battery as a power source and processing the biological electrical signal detected by the biomedical electrode pad, wherein
the biomedical electrode pad comprises:
an attachment sheet having water vapor permeability, the attachment sheet being elastically stretchable and having an electrically insulating property while including, on a back surface side, an adhesive surface suitable to be attached to the skin of the living body;
a plurality of electrodes located apart from one another on the back surface side of the attachment sheet and exposed to the back surface side;
a plurality of connecting parts that are located at a central part of the back surface side of the attachment sheet and covered with electrical insulation while being exposed to a front surface side through an opening of the attachment sheet; and
an electrode connecting wiring that is located on the back surface side of the attachment sheet and covered with electrical insulation while having a stretchable portion in at least a part of the electrode connecting wiring, and that electrically connects the plurality of electrodes with corresponding ones of the plurality of connecting parts, and
the storage case comprises:
a receptacle case including a plurality of leg parts fixed to a central part of the front surface side of the attachment sheet of the biomedical electrode pad, and forming, between the leg parts, a gap partially between a front surface of the attachment sheet and the receptacle case;
a cover case that is watertightly and detachably fitted to the receptacle case; and
an elastic connecting member penetrating through an opening in each of the leg parts of the receptacle case and through the opening at the central part of the attachment sheet to be located within the openings such that the elastic connecting member is elastically in contact with each of the plurality of connecting parts exposed from the opening at the central part of the attachment sheet to the front surface side of the attachment sheet and with the biological signal processing circuit unit in the storage case to electrically connect the each of the plurality of connecting parts and the biological signal processing circuit unit,

wherein the plurality of leg parts of the receptacle case each include a proximal part fixed to the receptacle case and a distal end part detachably fitted to the proximal part while being fixed to the central part of the front surface side of the attachment sheet of the biomedical electrode pad.

2. The storage case with the biomedical electrode pad according to claim 1 , wherein the plurality of electrodes include an indifferent electrode and a plurality of detecting electrodes.

3. The storage case with the biomedical electrode pad according to claim 1 , wherein a flexible wiring board is constituted by: a resin substrate; the plurality of electrodes arranged on a lower surface of the resin substrate; the plurality of connecting parts arranged on an upper surface of the resin substrate; and the electrode connecting wiring arranged on the upper surface of the resin substrate, an end part of the electrode connecting wiring penetrating through the resin substrate to electrically connect the plurality of electrodes with corresponding ones of the plurality of connecting parts.

4. The storage case with the biomedical electrode pad according to claim 1 , wherein at least one of the receptacle case and the cover case is made of a soft resin.

5. The storage case with the biomedical electrode pad according to claim 1 , wherein
the proximal part is formed in an annular shape so as to surround an entire circumference around the opening in each of the leg parts wherein the elastic connecting member is located,
the distal end part is formed in an annular shape so as to surround an entire circumference around the opening at the central part of the attachment sheet wherein the elastic connecting member is located, and
an annular concave part provided on one of the proximal part and the distal end part and an annular convex part provided on another of the proximal part and the distal end part are fitted to each other so that the proximal part and the distal end part are detachably and watertightly fitted to each other.

6. A biological signal processing device including the storage case with the biomedical electrode pad according to claim 1 , wherein
the biological signal processing circuit unit is stored inside the storage case with the biomedical electrode pad.
