Abstract

There is provided a biological information measuring apparatus, which permits to release constriction of capillary vessels a human body to provide stable measurement results of biological information and a proper S/N ratio.

The biological information measuring apparatus 1 includes a beam-emitting type sensor device 10 provided on a mounting unit 2 to optically measure biological information of a subject 4. The beam-emitting type sensor device 10 is placed in a position so as to be in a non-contact state relative to the subject 4 when measuring the biological information.

Claims

1. A biological information measuring apparatus, which comprises:

a mounting unit having a contact surface, which is to come into contact with a surface of a subject, the mounting unit being provided with a recess formed thereon;

a laser beam-emitting type sensor device being received in said recess of the mounting unit, said laser beam-emitting type sensor device being capable of optically measuring biological information of the subject, wherein;

a space is provided between the laser beam-emitting type sensor device and an extended plane of the contact surface of the mounting unit to ensure a non-contact area of the biological information measuring apparatus relative to the subject when measuring said biological information, and wherein;

the laser beam-emitting type sensor device comprises;

a sensor body received in the recess of the mounting unit; and

a cover plate placed on the sensor body; and

said space is provided between the cover plate of the laser beam-emitting type sensor device and the extended plane of the contact surface of the mounting unit.

2. The biological information measuring apparatus as claimed in claim 1, wherein:

said recess of the mounting unit is provided at an opening peripheral edge thereof with a chamfered portion.

3. The biological information measuring apparatus as claimed in claim 1 wherein:

the mounting unit having said recess is provided at the opening peripheral edge thereof with a curved surface.

4. The biological information measuring apparatus as claimed in claim 1, wherein:

the mounting unit having said recess is provided at the opening peripheral edge thereof with a projection having a contact portion, which serves as said contact surface, said contact portion having a semi-circular cross-section.
