Abstract

A motion sensor for measuring motion information of a subject comprises a coil substrate having transmitting or receiving coils piled one on top of another and a holder in which the coil substrate is mounted. Formed on the holder are curved surfaces to which an adhesive sheet is stuck and at which the holder is attached to a nail of a subject via the adhesive sheet. Further, there is provided a casing where first and second containing space are formed to contain measurement instruments including an adhesive member where a plurality of the adhesive sheets are laid one on top of another, the motion sensor, and the like.

Claims

1. A motor function measuring sensor including a right hand sensor and a left hand sensor so as to measure motor function of fingers of a subject, each of the right hand sensor and the left hand sensor, comprising:

a magnetic field generating unit for generating a magnetic field;

a magnetic field detecting unit for detecting the magnetic field;

a first holder to be attached to a first predetermined part of a living body for holding the magnetic field generating unit;

a second holder to be attached to a second predetermined part of the living body for holding the magnetic field detecting unit, a distance between the first and second parts being variable by motion of the living body; and

a sticking part, the magnetic field detecting unit outputting a measurement signal based on an intensity of the detected said magnetic field to detect a motor function of the living body,

a distinguishing part for distinguishing the sensor to be used between the right hand and left hand of the living body, and

an electric wire electrically connected to the magnetic field generating unit and the magnetic field detecting unit, wherein the electric wire has a connector unit including a plurality of pins as the distinguishing part and at least one of the first holder and the second holder includes an attachment surface, the sticking part detachably attaches the attachment surface to the living body,

wherein there is a difference in a number of the pins between the right hand sensor and the left hand sensor.

2. The motor function measuring sensor according to claim 1, wherein the sticking part comprises a seat including adhesive surfaces on its front and back sides, respectively.

3. The motor function measuring sensor according to claim 2, wherein the seat comprise a tab having non-adhesive surfaces.

4. The motor function measuring sensor according to claim 1, wherein the attachment surface comprises a slit along an axis direction across the attachment surface.

5. The motor function measuring sensor according to claim 1, wherein each of the first and second holders comprises:

an upper holder and a lower holder;

a coil substrate including a through hole into which the electric wire is inserted and the electric wire is electrically connected to a circuit on the substrate.

6. The motor function measuring sensor according to claim 1, further comprises:

a character or a mark indicating either of the right hand or the left hand of the living body.

7. The motor function measuring sensor according to claim 1, further comprises:

the distinguishing part including a color on an outer surface of the electric wire for indicating either of the right hand or the left hand of the living body.

8. The motor function measuring sensor according to claim 1,

wherein the number of the pins is either a first value for the right hand or a second value for the left hand, which is different from the first value.

9. ,The motor function measuring sensor according to claim 1, further comprises:

a string member including an engaging part for engaging with the electric wire, the engaging part being slidable relative the electric wire; and

a clip for clipping a part of clothes of the living body.
