Abstract

A probe which is to be attached to a finger of a subject to acquire physiological parameter of the subject includes a light emitter that emits a light beam toward the finger, a light detector that outputs a signal corresponding to a light beam that is transmitted through or reflected from the finger, a first holding face that has a portion which is faced with a nail of the finger and another portion which is faced with a side face of the finger, and a second holding face that has a portion which is faced with a pad of the finger and another portion which is faced with the side face of the finger. In a state where the probe is attached to the finger, the first holding face and the second holding face are placed to be continuous to each other.

Claims

1. A probe which is to be attached to a finger of a subject to acquire physiological parameter of the subject comprising:

a light emitter that emits a light beam toward the finger;

a light detector that outputs a signal corresponding to a light beam that is transmitted through or reflected from the finger;

a first holding face that has a portion which is faced with a nail of the finger and another portion which is faced with a side face of the finger; and

a second holding face that has a portion which is faced with a pad of the finger and another portion which is faced with the side face of the finger,

wherein, in a state where the probe is attached to the finger, the first holding face and the second holding face are placed to be continuous to each other.

2. The probe according to claim 1, wherein a section of the first holding face as viewed from a fingertip side of the subject has a shape which extends along a nail side of the finger, and a section of the second holding face as viewed from the finger tip side of the subject has a shape which extends along a pad side of the finger.

3. The probe according to claim 1, wherein at least one of the light emitter and the light detector is placed to be faced with a pad side of the finger.

4. The probe according to claim 2, wherein at least one of the light emitter and the light detector is placed to be faced with a pad side of the finger.

5. The probe according to claim 1, wherein the second holding face is black.

6. The probe according to claim 2, wherein the second holding face is black.

7. The probe according to claim 3, wherein the second holding face is black.

8. The probe according to claim 4, wherein the second holding face is black.

9. The probe according to claim 5, wherein the first holding face is black.

10. The probe according to claim 1 further comprising:

a left side portion that is placed to be faceable with a left side face of the finger;

a right side portion that is placed to be faceable with a right side face of the finger; and

a hinge portion that connects the left side portion and the right side portion together in a manner that a gap between the left side portion and the right side portion is adjustable,

wherein the light emitter is placed in one of the left side portion and the right side portion,

the light detector is placed in another one of the left side portion and the right side portion, and

each of the left side portion and the right side portion has the first holding face and the second holding face.

11. The probe according to claim 2 further comprising:

a left side portion that is placed to be faceable with a left side face of the finger;

a right side portion that is placed to be faceable with a right side face of the finger; and

a hinge portion that connects the left side portion and the right side portion together in a manner that a gap between the left side portion and the right side portion is adjustable,

wherein the light emitter is placed in one of the left side portion and the right side portion,

the light detector is placed in another one of the left side portion and the right side portion, and

each of the left side portion and the right side portion has the first holding face and the second holding face.

12. The probe according to claim 3 further comprising:

a left side portion that is placed to be faceable with a left side face of the finger;

a right side portion that is placed to be faceable with a right side face of the finger; and

a hinge portion that connects the left side portion and the right side portion together in a manner that a gap between the left side portion and the right side portion is adjustable,

wherein the light emitter is placed in one of the left side portion and the right side portion,

the light detector is placed in another one of the left side portion and the right side portion, and

each of the left side portion and the right side portion has the first holding face and the second holding face.

13. The probe according to claim 4 further comprising:

a left side portion that is placed to be faceable with a left side face of the finger;

a right side portion that is placed to be faceable with a right side face of the finger; and

a hinge portion that connects the left side portion and the right side portion together in a manner that a gap between the left side portion and the right side portion is adjustable,

wherein the light emitter is placed in one of the left side portion and the right side portion,

the light detector is placed in another one of the left side portion and the right side portion, and

each of the left side portion and the right side portion has the first holding face and the second holding face.

14. The probe according to claim 5 further comprising:

a left side portion that is placed to be faceable with a left side face of the finger;

a right side portion that is placed to be faceable with a right side face of the finger; and

a hinge portion that connects the left side portion and the right side portion together in a manner that a gap between the left side portion and the right side portion is adjustable,

wherein the light emitter is placed in one of the left side portion and the right side portion,

the light detector is placed in another one of the left side portion and the right side portion, and

each of the left side portion and the right side portion has the first holding face and the second holding face.

15. The probe according to claim 10, wherein the hinge portion elastically urges the left side portion and the right side portion to cause the left side portion and the right side portion to approach each other.
