Abstract

A bio-information detecting apparatus includes: a band member curved in a C-shape, and attached around a neck part of an examinee from a back side of the neck part; and a pair of electrodes for cardiac potential measurement disposed at positions on the band member that come into contact with right and left skin surfaces of the neck part, and in the pair of electrodes, a position of the electrode on the right is located relatively more frontward than a position of the electrode on the left. The bio-information detecting apparatus further includes a substrate to optically measure a blood oxygen saturation for pulse measurement at a position on the band member that comes into contact with the neck part of the examinee, and a pressing force of the substrate against the skin surface of the neck part is 0.96 to 1.21 [N/cm²].

Claims

1. A bio-information detecting apparatus comprising:

a band member curved in a C-shape, the band member attached in a manner as to extend along a neck part of an examinee from a back side of the neck part toward both left and right lateral sides of the neck part; and

a pair of electrodes for cardiac potential measurement of the examinee, the pair of electrodes disposed at positions on the band member that come into contact with right and left skin surfaces of the neck part of the examinee,

wherein

of the pair of electrodes, a position of the electrode located on the right skin surface of the neck part of the examinee is located relatively more frontward than a position of the electrode located on the left skin surface of the neck part of the examinee.

2. The bio-information detecting apparatus according to claim 1, wherein

the electrode on the right skin surface of the neck part is disposed in a more frontward region on the band member than the right lateral side of the neck part of the examinee, and

the electrode on the left skin surface of the neck part is disposed at a more backward position on the band member than the left lateral side of the neck part of the examinee.

3. The bio-information detecting apparatus according to claim 1, further comprising

a substrate having alight emitting part and a light receiving part each of which optically measures a blood oxygen saturation for pulse measurement of the examinee, the substrate disposed at a position on the band member that comes into contact with the neck part of the examinee,

and

in a state in which the substrate is in contact with a skin surface of the neck part of the examinee, a pressing force of the substrate against the skin surface of the neck part is 0.96 to 1.21[N/cm²].

4. The bio-information detecting apparatus according to claim 1,

wherein

the contact surface of each of the pair of electrodes that comes into contact with the skin surface of the neck part of the examinee is in a flat state or in a curved state in a direction in which a center portion of the contact surface protrudes more than a peripheral edge of the contact surface toward the skin surface of the neck part of the examinee, the protrusion being within a range of not more than 1 mm.

5. The bio-information detecting apparatus according to claim 1,

wherein

a contact area of each of the pair of electrodes that comes into contact with the skin surface of the neck part of the examinee is more than 25 mm².

6. A bio-information detecting apparatus comprising:

a band member curved in a C-shape, the band member attached in a manner as to extend along a neck part of an examinee from a back side of the neck part toward both left and right lateral sides of the neck part to a region more frontward than the left and right late al sides of the neck part; and

a substrate disposed at a position on the band member that comes into contact with the neck part of the examinee, the substrate having a light emitting part and a light receiving part that are used for optically measuring a blood oxygen saturation for pulse measurement of the examinee,

wherein

in a state in which the substrate is in contact with a skin surface of the neck part of the examinee, a pressing force of the substrate against the skin surface of the neck part is 0.96 to 1.21[N/cm²].
