Abstract

A bio-information measuring apparatus is provided, which suppresses pressure on a capillary vessel of body, stabilizes a measuring result of bio-information, and obtains a good S/N ratio.

In an bio-information measuring apparatus 1 in which a self-emission-type sensor device 10 for optically measuring bio-information of specimen 4 is attached to an attaching member 2, the attaching member 2 is composed of elastic material, and the attaching member 2 is arranged to be brought into contact with the specimen 4 at the time of measuring the bio-information.

Claims

1. A bio-information measuring apparatus in which a self-emission-type sensor device for optically measuring bio-information of specimen is attached to an attaching member,

wherein the attaching member is composed of elastic material, and is brought into contact with the specimen at the time of measuring the bio-information,

a hollow is formed in the attaching member, and the self-emission-type sensor device is contained in the hollow, and

a slanted slope is formed at an inner edge of an aperture of the hollow of the attaching member containing the self-emission-type sensor device with the diameter of the aperture decreased toward the self-emission type sensor device.

2. A bio-information measuring apparatus according to claim 1,

wherein the self-emission-type sensor device comprises:

a holding member,

an irradiating unit located in the holding member which irradiates light onto the specimen, and

a light-receiving unit located in the holding member which detecting light from the specimen based on the irradiated light, and

wherein a front surface plate is located in front of the irradiating unit and the light-receiving unit and in an opposed relationship with the specimen, and

the light is irradiated and received through the front surface plate.

3. An bio-information measuring apparatus according to claim 1,

wherein a distance between a center of the irradiating unit and a center of the light receiving unit is d, a minimum width of aperture of the hollow is W, and W is greater than d.

4. A bio-information measuring apparatus in which a self-emission-type sensor device for optically measuring bio-information of specimen is attached to an attaching member,

wherein a hollow is formed in the attaching member, the self-emission-type sensor device is contained in the hollow, and an elastic member of permeability is mounted on at least an upper surface of the self-emission-type sensor device,

the self-emission-type sensor device is located in such a way that an upper surface of the elastic member of permeability is in the same level as an upper surface of the attaching member, and

another elastic member of permeability covers an upper surface of the elastic member of permeability and an upper surface of the attaching member.

5. An bio-information measuring apparatus in which a self-emission-type sensor device for optically measuring bio-information of specimen is attached to an attaching member,

wherein a hollow is formed in the attaching member, the self-emission-type sensor device is contained in the hollow, and a member of permeability is mounted on at least an upper surface of self-emission-type sensor device,

wherein the self-emission-type sensor device comprises:

a holding member,

an irradiating unit located in the holding member which irradiates light onto the specimen, and

a light receiving unit located in the holding member which detects light from the specimen based on the irradiated light, and

wherein a distance between a center of the irradiating unit and a center of the light receiving unit is d, a minimum width of aperture of the hollow is W, and W is greater than d, and

wherein the member of permeability is located in such a way that an upper surface of the member of permeability is slightly lower than an upper surface of the attaching member.
