Problems solved by technology

In this case, since the sensitivity of the biosensor needs to be expected to form the lot discrimination electrode, if the sensitivity of the expected sensor differs from the actual sensor sensitivity, the biosensor needs to be discarded, resulting in a decrease in yield.
In addition, although it is conceivable to form the electrodes for measurement and the electrodes for lot discrimination in different processes, since in this case, the steps required for forming the electrodes for lot discrimination are increased.
Moreover, the added process is a complicated process such as screen printing or vapor deposition, so the work efficiency is low
[0007] The second problem arises when the biosensor is mounted on the measurement device due to the configuration that the terminal for discrimination contacts the electrode for batch discrimination of the biosensor.
That is, for measurement devices, biosensors are repeatedly mounted, and the terminals for determination are prone to deterioration due to such repetitions.
On the other hand, if the terminal for judgment is degraded, frequent repairs and maintenance of the measuring device are required, and this will become the main cause of shortening the life of the device.
[0008] The third problem is that the electrodes for lot discrimination are formed on the same side of the substrate as the electrodes for measurement, and the problem occurs on the measurement device.
Therefore, it is necessary to arrange these terminals in an extremely narrow range, and in addition, there are great restrictions on arranging these terminals.
As a result, in the design of the measurement device, there are great restrictions on the part where the biosensor is mounted, and the degree of freedom in design is reduced
This problem is more significant when the amount of information to be identified by the measuring device is large and a large number of terminals for discrimination are required.

Embodiment approach 1

[0059] Such as figure 1 As shown, an analysis device 1A is a device in which a biosensor 2A is installed and used. In this analysis device 1A, the concentration of a specific component in a sample supplied to the biosensor 2A can be measured electrochemically.

[0060] The schematic structure of the analysis device 1A generally includes: measurement terminals 10A, 11A, voltage application unit 12A, current value measurement unit 13A, storage unit 14A, measurement line selection unit 15A, detection unit 16A, control unit 17A, calculation unit 18A and information identification Part 19A. The details of each part of 10A-19A will be described later.

[0061] Additionally, if Figure 1 to Figure 3 As fully shown, the biosensor 2A has a cover 20A, a spacer 21A, and a substrate 22A, and these parts constitute a flow path 23A.

[0062] The cap 20A has a hole 24A required to discharge the gas inside the flow path 23A. The separator 21A has a groove 25A. The groove 25A is for defi...

Embodiment approach 3

[0100] Such as Figure 13A as well as Figure 13B The shown biosensor 2A is the same as Embodiment 1 (refer to figure 2 to Figure 4) is the same. That is, the biosensor 2A has a function of allowing the analyzer 1C to recognize information by selecting whether to provide the protrusion 29Aa or not to provide the protrusion 29Aa at a predetermined position set at the end of the substrate 22A.

[0101] In addition, the analyzer 1C shown in the figure is different from the first and second embodiments in the configuration of the information recognition unit 19C. The information recognition unit 19C has three capacitive sensors 190C, although not clearly shown in the drawings. Capacitance sensor 190C has first and second electrodes 195C and 196C, and first and second electrodes 195C and 196C are configured to be relatively movable along the insertion direction of biosensor 2A. That is, the capacitive sensor 190C is configured so that the facing area of ​​the first and second el...

Description

technical field [0001] The present invention relates to techniques for analyzing specific components in a sample. More specifically, the present invention relates to an analysis member, an analysis device, and an assembly of the analysis device and the analysis member used when analyzing a sample. Background technique [0002] As a general method for measuring a specific component in a body fluid, for example, the concentration of glucose in blood, there is one that utilizes an oxidation-reduction reaction using an oxidoreductase as a catalyst. In addition, a simple blood sugar measuring device of a size that can be placed in the palm of a hand can be widely used for easily measuring the blood sugar level at home and in places outside the home. After a disposable biosensor is mounted on the simple blood glucose measuring device while an enzyme reaction field is provided, the blood glucose is measured by supplying blood to the biosensor. [0003] The sensor sensitivity of e...
