れていた。Such a blood sugar level measuring device measures a blood sugar level by measuring a glucose (GLUCOUSE C 6 H 12 O 6 ) value of a collected body fluid. This blood glucose measurement device, for example, to remove the stratum corneum of a part of the skin of the subject to expose the epidermis,
When the suction cell is brought into contact with the suction cell and suctioned through a suction pump or the like, the body fluid exudes. This body fluid is collected and the glucose level is measured. The conventional configuration of such a suction cell was configured as shown in FIG. FIG. 7A shows a suction cell (1).
7B shows a bottom view. In FIGS. 7A and 7B, the cell body (2) is made of a metal or synthetic resin having a diameter of about 40φ in the form of a flat plate having a thickness of about 12 mm. A mesh (4) in which (3) is formed and fine stainless steel wire is finely knitted in the counterbore (3).
Is loosely fitted. The mesh (4) is stretched over an annular frame (5). The mesh (4) is provided so that the suction pressure is evenly applied to the suction portion of the skin layer and the skin does not adhere to the counterbore (3) of the cell body (2). A double-sided adhesive tape (10) is attached to the circumference (9) other than the counterbore (3) of the cell body (2) so as to adhere to the skin, and the surface side of the cell body (2) Then, a tube (8) is covered with an outer tube (7) for sending a body fluid to a measuring section or forming a suction path (6) for adsorbing a suction cell to the skin by a suction pump.
Is connected to the switching valve. The suction passage (6) reaches the counterbore (3) and is configured to suck the body fluid through the switching valve.

After performing a tape stripping process of removing the layer) using an adhesive tape or the like, the suction cell (1) is brought into close contact with a predetermined position on the skin with a double-sided adhesive tape (10), and the body fluid is sucked through a suction pump or the like. Thus, the body fluid (2) is made of a rigid material such as a metal or a synthetic resin. The reason why such a rigid material is used is that the absolute pressure of the suction device is about 400 mmHg so as to maintain the shape against external force at the time of suction and to prevent pressure leakage, etc. The cell body (2) is rigid. If the skin and the cell body (2) are made of a suitable material, the mounting surface between the skin and the cell body (2) has a circular shape like an arm or a finger, or if the surface has irregularities, it will not be possible to mount it. The double-sided adhesive tape (10) adhered to the peripheral part (9) of the cell body (2) by the movement of the skin and muscles including the vicinity of the device part with the movement and movement.
Peels off, and furthermore, pressure leakage occurs. Further, when a slight impact acts on the cell body (2), the impact force is transmitted as it is to the double-sided adhesive tape on the circumferential portion (9), which is the mounting surface of the skin, because the cell body (2) has no flexibility. , Causing peeling and pressure leakage.

とは明白である。According to the configuration of the present example, even if the subject moves his / her body or an external force or impact is applied to the suction cell (1), the elastic member absorbs these movements and the cell body (2) comes into close contact. Even if the surface of the skin (11) has some irregularities, it can be absorbed. Further, a double-sided adhesive tape may be attached to the tip of the protruding portion (28) as in the conventional case so as to increase the degree of close contact with the skin (11). FIG. 4 is an external view of a suction device for explaining the effect of the present example. That is, according to the configuration of this example, as shown in FIG. 4, even if the skin (11) to which the cell body (2) is attached has a predetermined curvature like an arm, the elastic member (25) is large at the center. The suction device can be flexibly deformed so as to be displaced and smallly displaced in the peripheral portion, and can be closely adhered to the skin in accordance with the curvature, and a suction device which does not cause pressure leakage or peeling can be obtained. In each of the embodiments described above, the elastic member made of cylindrical rubber is adhered to the cell body (2). For example, as shown in FIG. 5, a rubber (25a) formed in a ring shape is used for the cell body. The elastic member (25) is formed in a bellows shape (25b) as shown in FIG. 6 and fixed to the outer peripheral portion (27), and is fixed to the outer peripheral portion (27). It is apparent that various modifications can be made without departing from the scope of the present invention.
