Claims

Determining the light irradiation position on the skin surface and the light receiving position on the skin surface based on the depth of the target blood vessel from the skin surface;
Irradiating the irradiation position with light;
Measuring a blood component using a light reception result at the light receiving position;
A blood component measuring method comprising:

The determining includes increasing the distance between the irradiation position and the light receiving position as the depth increases.
The blood component measuring method according to claim 1.

The determining includes determining the irradiation position and the light receiving position so that the irradiation position and the light receiving position are positioned to sandwich the target blood vessel on the skin surface,
The blood component measuring method according to claim 1 or 2.

In the skin surface, the determining includes moving either the irradiation position or the light receiving position away from the target blood vessel as the depth increases.
The blood component measuring method according to claim 3.

The determining includes determining the irradiation position and the light receiving position on the target blood vessel on the skin surface,
The blood component measuring method according to claim 1 or 2.

Determining a reference position on the skin surface, a first position that sandwiches the target blood vessel between the reference positions, and a second position that does not sandwich the target blood vessel between the reference positions; Performing either one of irradiation and light reception at the reference position and performing the other at the first position and the second position by repeatedly changing the first position;
Based on a result of the light receiving in the execution of the repeat, and determining the depth of the target blood vessel,
The blood component measurement method according to any one of claims 1 to 5, further comprising:

A position determining unit that determines a light irradiation position on the skin surface and a light receiving position on the skin surface based on the depth of the target blood vessel from the skin surface;
An irradiation control unit that performs control to irradiate light to the irradiation position;
A measurement unit for measuring a blood component using a light reception result at the light receiving position;
A blood component measuring apparatus comprising:

The position determination unit determines a wider interval between the irradiation position and the light receiving position as the depth increases.
The blood component measuring apparatus according to claim 7.

The position determining unit determines the irradiation position and the light receiving position on the skin surface so that the irradiation position and the light receiving position are positioned to sandwich the target blood vessel;
The blood component measuring device according to claim 7 or 8.

The position determining unit determines either the irradiation position or the light receiving position away from the target blood vessel as the depth increases on the skin surface.
The blood component measuring apparatus according to claim 9.

The position determining unit determines the irradiation position and the light receiving position on the target blood vessel on the skin surface;
The blood component measuring device according to claim 7 or 8.

Determining, on the skin surface, a reference position, a first position that sandwiches the target blood vessel between the reference position, and a second position that does not sandwich the target blood vessel between the reference position; One of irradiation and light reception is performed at the reference position, and the other is performed at the first position and the second position. The first position is changed repeatedly, and the light is received in the repeated execution. Based on the result, an acquisition unit for obtaining the depth of the target blood vessel,
The blood component measurement device according to any one of claims 7 to 11, further comprising:

The medical device which comprises the blood component measuring device as described in any one of Claims 7-12 .
