[Conventional technology]

For the measurement of blood glucose level, conventionally, a method of directly collecting blood from a human body and inspecting it has been adopted.

As a simple blood glucose meter, for example, there is a method of puncturing a finger of a human body with a needle and scratching it, transferring a small amount of blood adhering to the needle tip to a test strip, and measuring the blood glucose level from the blood adhering to the test strip. Has been taken.

This simple blood glucose meter can measure subtle changes in blood glucose level as compared with a urine glucose test, and is used daily by many patients who need insulin injection. However, collecting blood by puncturing a needle in this way is called invasiveness that gives pain to the subject. Also,
There is a problem in that the subject is remarkably distressed due to inconveniences such as the skin of the fingertip being hardened or roughened, for example, with respect to a regular inspection after every meal or every 30 minutes.

On the other hand, without collecting blood, collecting body fluid,
A method of measuring a blood glucose level by measuring the glucose level has been proposed. Since the glucose level of this body fluid has a correlation with the blood glucose level of blood, it is possible to easily measure the blood glucose level by collecting a small amount of body fluid.

In the case of this method, for example, a portion of the stratum corneum of the skin of the subject is removed to expose the dermis, and for example, when aspiration is performed by contacting a funnel-shaped suction cell for body fluid extraction here, body fluid exudes, The blood glucose level is measured by collecting this body fluid and measuring the glucose level of the enzyme contained therein.

Conventionally, this body fluid extraction suction cell is fixed to the human body by pressing, or the body fluid extraction suction cell (1) is fixed as shown in the schematic cross-sectional view of FIG. A suction cell (1) for extracting a body fluid is obtained by fixing the band (9) by screwing and locking the band (9) to the arm of the human body with buckles (8) attached to both ends of the band (9). Was set at a predetermined position on the arm of the human body.

However, when the method of holding by hand is adopted, stable measurement may not be performed, and when the band (9) is tightened by the buckle (8), there is a problem that it is difficult for the subject to perform the locking work, Further, when the suction cell (1) is fixed to the band (9) by screwing, the weight of the suction cell (1) for body fluid extraction is reduced due to an increase in the thickness of the attachment portion of the suction cell (1). Inhibit. Further, the suction cell (1) needs to be washed each time it is used, but in the case of screwing or the like, the attachment / detachment work is complicated and the maintenance work takes time.
