Problems solved by technology

Therefore, not only the blood glucose level measurement cannot be performed in the installed biosensor 90, but also the fusion of the first electrode 93 of the biosensor 90 adheres to the first terminal 95 of the blood glucose level measuring device 91, which will change the resistance value of the first terminal 95. , will cause errors in the subsequent determination of the response current value

Embodiment Construction

[0035] Hereinafter, first to sixth embodiments of the present invention will be described with reference to the drawings.

[0036] First, refer to Figure 1 to Figure 7 A first embodiment of the present invention will be described.

[0037] figure 1 as well as figure 2 The shown biosensor X1 is a disposable structure, and is used by being attached to the connection part 10 of the analysis device 1 . Figure 3 and Figure 4 As shown, the biosensor X1 has a plate-like form in which a cover 4 is laminated on the upper surface 20 of the substrate 2 through a spacer 3 , and these elements 2 to 4 constitute a flow path 5 and a handle 6 .

[0038] The partition 3 is used to specify the size of the flow path 5, such as Figure 5 As shown, there is a slot 30 with an open front end. The width dimension and the length dimension of the flow path 5 are defined by this notch 30 . The open portion 31 at the front end of the notch 30 constitutes a sample introduction port 50 for introd...

Abstract

The present invention relates to an analytical tool (X1) to be mounted to an analytical apparatus (1) which includes a plurality of terminals (11, 12) and an analysis circuit (13). The analytical tool includes a plurality of electrodes (21, 22) coming into contact with the plurality of terminals (11, 12) when mounted to the analytical apparatus (1). In the analytical tool (X1), at least one (12) of the electrodes (21, 22) serves as a disturbing-noise countermeasure electrode to which disturbing noise is more likely to come in comparison with the other electrodes (11) than the above-mentioned electrode (12).

Description

technical field [0001] The present invention relates to an analysis tool used for analyzing a specific component in a sample (for example, an analysis tool used for measuring a blood sugar level). Background technique [0002] As a general method for measuring blood sugar level, there is a method utilizing oxidation-reduction reaction. On the other hand, simple blood sugar level measurement devices of a size that can be grasped by the palm are widely used so that the blood sugar level can be easily measured at home or on a business trip. In this simple blood sugar level measuring device, a disposable biosensor providing an enzyme reaction field is installed, and the blood sugar level is measured by supplying blood to the biosensor. [0003] As a method of measuring the blood sugar level, there is an electrochemical method. In this method, as shown in FIG. 14 , the blood sugar level is measured by attaching the biosensor 90 to the blood sugar level measuring device 91 (for ...
