Abstract

A sensor insertion method for inserting a sensor into a user'"'"'s body is provided. The method includes a unit fixing step of regulating a relative position between a sensor control unit and an inserting unit, where the sensor control unit is in a sensor insertion allowing state, and the inserting unit contains the sensor. In this step, the sensor control unit and the inserting unit are fixed to an insertion target portion of the user. Then, in a sensor inserting step, the inserting unit is caused to insert the sensor into the insertion target portion. In a sensor connecting step, the sensor control unit is shifted from the sensor insertion allowing state to a sensor connecting state, whereby electrical conduction is established between the sensor in the insertion target portion and the sensor control unit.

Claims

1. A sensor insertion method for inserting a sensor into a user'"'"'s body, the method comprising:

a unit fixing step of regulating a relative position between a sensor control unit and an inserting unit, the sensor control unit being in a sensor insertion allowing state, the inserting unit containing the sensor therein, and of fixing the sensor control unit and the inserting unit to an insertion target portion of the user;

a sensor inserting step of causing the inserting unit to insert the sensor into the insertion target portion; and

a sensor connecting step of shifting the sensor control unit from the sensor insertion allowing state to a sensor connecting state, thereby establishing electrical conduction between the sensor in the insertion target portion and the sensor control unit.

2. The sensor insertion method according to claim 1, wherein, in the unit fixing step, after the inserting unit is fixed to the insertion target portion, the relative position of the sensor control unit with respect to the inserting unit is regulated and the sensor control unit is fixed to the insertion target portion.

3. The sensor insertion method according to claim 1, wherein, in the unit fixing step, after the sensor control unit is fixed to the insertion target portion, the relative position of the inserting unit with respect to the sensor control unit is regulated and the inserting unit is fixed to the insertion target portion.

4. The sensor insertion method according to claim 1, wherein, in the unit fixing step, after the relative position between the sensor control unit and the inserting unit is regulated, the sensor control unit and the inserting unit are fixed to the insertion target portion.

5. The sensor insertion method according to claim 4, wherein, in the unit fixing step, after the relative position between the sensor control unit and the inserting unit is regulated, the inserting unit is fixed to a unit base secured to the insertion target portion.

6. The sensor insertion method according to claim 4, wherein, in the unit fixing step, after the relative position between the sensor control unit and the inserting unit is regulated and the inserting unit is fixed to a unit base, the sensor control unit and the inserting unit are fixed to the insertion target portion by securing the unit base to the insertion target portion.

7. The sensor insertion method according to claim 1, wherein, in the sensor connecting step, the sensor and the sensor control unit are electrically connected to each other by moving a part or the whole of the sensor control unit.

8. The sensor insertion method according to claim 1, further comprising a unit releasing step of releasing the inserting unit from the insertion target portion after the sensor connecting step.

9. An analysis method comprising an analysis step of performing an analysis using the sensor after the sensor insertion method according to claim 1 is performed.

10. A sensor insertion device for inserting a sensor for analysis into a user'"'"'s body, the device comprising:

an inserting unit that inserts the sensor into an insertion target portion of the user; and

a sensor control unit regulated in relative position with respect to the inserting unit and configured to selectively take a sensor insertion allowing state allowing the insert of the sensor while the inserting unit is fixed to the insertion target portion, and a sensor connecting state in which the sensor control unit is electrically connected to the sensor inserted into the insertion target portion.

11. The sensor insertion device according to claim 10, wherein the sensor control unit is shifted from the sensor insertion allowing state to the sensor connecting state when a part or the whole of the sensor control unit is moved in a direction along a surface of the insertion target portion.
