The sensor holder 18 is securely held in the storage portion 15 by being fitted therein against the elastic force of the storage portion 15 for the sensor holder, and is protected from an external impact or the like by the impact absorbing force of the elastic force.

As shown in FIG. 5, the sensor holder 18 accommodates a sensor continuum 19 formed by connecting a plurality of blood glucose measuring sensors 14 to each other. The blood glucose measurement sensor 14 is a sensor (enzyme electrode) that uses a hydrogen peroxide electrode and an oxidase that converts oxygen into hydrogen peroxide. It is a disposable type because it is attached to measure the blood glucose level and then detached from the sensor holder 18 and discarded.

The blood glucose measurement sensor 14 will be described in detail with reference to FIGS. 5 and 6, for example, has the following configuration. The blood glucose measuring sensor 14 has a width W of 5 mm and a total length L of 12 mm, for example. A notch 20A is formed in the substrate 20 of the sensor continuum 19, and each blood glucose measurement sensor 14 can be separated from the sensor continuum 19 by the notch 20A.

FIG. 5 shows the blood glucose measurement sensor 14 without the protective layer 21 shown in FIG. 6. Reference numeral 22 is a counter electrode, 23 is a first working electrode, 24 is a second working electrode, and 25 is a reference electrode. Therefore, these electrodes 22, 23, 24, 25 form a detection portion. Reference numeral 26 is a terminal portion electrically connected to each electrode 22, 23, 24, 25. Reference numeral 27 in FIG. 6 is a non-woven fabric for sample lubrication, which is arranged so as to cover the counter electrode 22. The protective layer 21 is provided so as to cover the first working electrode 23 and the reference electrode 25 via the space 21A for lubricating the sample.

Next, the sensor holder 18 that holds the blood glucose measurement sensor 14 will be described with reference to FIG. Since 30 is a holder main body for accommodating the vertically long sensor continuum 19, it has a vertically long shape as a whole, and a new sensor continuum 19 can be replenished. Reference numeral 31 denotes a sensor support portion formed at the tip of the holder main body 30, and the most advanced blood glucose measurement sensor 14 of the sensor continuum 19 housed in the holder body 30 is positioned on the sensor support portion 31. It

Reference numeral 32 denotes a slider provided on the back side of the holder main body so as to slide along the longitudinal direction of the holder main body 30. The slider 32 slides to measure each blood glucose of the sensor continuum 19. The sensor 14 is sequentially moved forward (on the side of the sensor support portion 31) and the blood glucose measuring sensor 14 at the forefront thereof is used at any time, and the blood glucose measuring sensor 14 after use is cut from the sensor continuum 19 via the notch 20A. Separated and discarded.

Reference numeral 33 denotes a connector, which is electrically connected to each of the terminal portions of the blood glucose measurement sensor 14 at the tip of the sensor supporting portion 31. A flexible cord 34 is connected to the connector 33, and the blood glucose measuring sensor 14 located on the sensor support 31 and the blood glucose measuring device body 2 are electrically connected via the cord 34.

Next, as shown in FIG. 7, the blood glucose measuring device main body 2 applies a potential to each of the electrodes 22, 23, 24, 25 of the blood glucose measuring sensor 14 located on the sensor support 31 to apply a current. The potentiostat section 40 for detecting the current, the A / D conversion section 41 for digitizing the current, the function generator section 42 for setting the voltage applied to the potentiostat section 40, and the blood glucose level obtained from the current value are displayed. It is composed of a blood glucose measurement display unit 5 for controlling a predetermined circuit such as the function generator unit 42, an arithmetic control unit 43, and a data storage unit 44.

As shown in FIG. 1 and the like, the alcohol cotton accommodating portion 16 is formed on the front end side of the upper half case 3 by a concave portion with a band or a lid, and the alcohol cotton and the wound disinfectant are disposed in the concave portion. Adhesive tape (not shown) with medicinal products is stored. The sensor holder storage portion 15 is formed on the front end side of the upper half case 3, while the alcohol cotton storage portion 16 is formed on the front end side of the upper half case 3, for example. 3 maintains a predetermined inclination angle with respect to the lower half case 4 (the lower half case 4 placed on a desk or the like), and the center of gravity of the upper half case 3 is as large as possible when the case body 1 is opened. This is because it is placed on the desk or the like in a stable state by being located on the rear end side (lower side), and the opening / closing operation of the case body 1 is facilitated.

That is, since the alcohol cotton or the adhesive tape with wound disinfectant stored in the alcohol cotton storage portion 16 is relatively lighter than the sensor holder 18, the alcohol cotton storage portion 16 is placed in the upper half. It is formed on the front end side of the case 3, while the sensor holder housing 15 is formed on the rear end side of the upper half case 3. The stabilization of the mounting state of the lower half case 4 on a desk or the like and the easy opening / closing operation of the case body 1 are performed by the upper half in the storage state or the non-storage state of the object to be stored in each storage section. It is also possible to make the case 3 side lighter than the lower half case 4 side.

Next, an elastically deformable hook 50 is formed on the front end side of the upper half case 3, and the hook 50 is elastically deformed to be hooked on the front end side of the lower half case 4. As a result, the closed state of the case body 1 is maintained. A predetermined switch (not shown) that is turned on and off in conjunction with the opening / closing operation of the case body 1 is provided on the front side of the hook 50 and the lower half case 4 on which the hook 50 is hooked. When the case body 1 is opened, the power of the blood glucose measuring device body 2 is automatically turned on when the switch is turned on, and the blood glucose can be measured by the blood glucose meter. When is closed, the power of the blood glucose measuring device main body 2 is automatically turned off by the OF of the switch.

Next, an example of use of the blood glucose meter of this embodiment will be described. For example, the blood glucose meter of the present embodiment is provided with various storage units of the case body 1, that is, a blood sampling device storage unit 8, an insulin syringe storage unit 9, an insulin storage unit 10, a sensor holder storage unit 15, an alcohol cotton storage unit. A blood collection tool 11, an insulin injector 12, insulin 13, a sensor holder 18 in which a sensor continuum 19 is housed, alcohol cotton and an adhesive tape with a wound disinfectant are respectively housed in a housing portion 16, and the case body 1 Closed and stored and carried by users such as patients.

Therefore, according to the blood glucose meter of the present embodiment, the various tools required for insulin therapy are stored in the respective storage portions of the case body 1 and stored and carried in the case body 1. As a result, it is possible to facilitate and improve the convenience of storing and carrying various tools that are used almost simultaneously for insulin therapy. In addition, for example, since only one case body 1 for storing and carrying those tools is required, it is possible to reduce the cost, size, weight, and compactness of the tools used for insulin therapy. .

Next, when the blood glucose meter is used, the case body 1 is opened and the blood collection tool 11 is taken out from each storage section, and then a small amount of blood of the patient is collected using the blood collection tool 11. Then, the sensor holder 18 is taken out from the sensor holder storage portion 15, and blood as a sample is spotted on the nonwoven fabric 9 of the blood glucose measurement sensor 14 located on the sensor support portion 31. The blood that has been spotted enters the detection section composed of the counter electrode 22, the first and second working electrodes 23 and 24, and the reference electrode 25 through the non-woven fabric 9, and the change in the current or voltage caused by this invasion occurs in the terminal section 8 and the connector. 9. The blood glucose level is output to the blood glucose measuring device main body 2 via the code 34, and the blood glucose level is measured. Since the measured blood glucose level is digitally displayed on the blood glucose measurement display unit 5, the patient can easily recognize the current blood glucose level of the patient. Then, by recognizing the blood glucose level, the patient uses the insulin syringe 12 taken out from the insulin syringe storage section 9 to inject a predetermined amount of insulin 13 adapted to the blood glucose level.

At the time of this insulin injection, the insulin 13 contained in the cartridge stored in the insulin storage portion 10 is taken out and used. When the injection needle is not integrated with the insulin syringe 12, the injection needle stored in a predetermined storage portion (not shown) of the case body 1 is taken out and used. Further, before and after the above-mentioned blood collection and insulin injection, the alcohol cotton contained in the alcohol cotton container 16 and the adhesive tape with a wound disinfectant are used to disinfect the skin and protect the wound.

As described above, according to the blood glucose meter of the present embodiment, the tools necessary for measuring the blood glucose level of the patient and injecting insulin are integrated in the case main body 1, so that it is easy to use. It is possible to improve efficiency and convenience. Further, the blood glucose meter of the present embodiment has a structure in which the power of the blood glucose measuring device main body 2 is automatically turned on when the case main body 1 is opened, and is automatically turned off when the case main body 1 is closed. As a result, a special operation for turning on / off the power supply of the blood glucose measurement device main body 2 is not required, and therefore, it is possible to improve the convenience or convenience during blood glucose measurement. In particular, this effect is that the blood glucose meter of the present embodiment is used by opening the case body 1 when using it, and by closing the case body 1 when not in use such as storage or carrying. Therefore, it is extremely meaningful.

The invention devised by the present inventor has been specifically described based on the embodiments, but the present invention is not limited to the embodiments and can be variously modified without departing from the gist thereof. Needless to say. For example, although the blood glucose measuring sensor 14 and the injection needle are disposable in the above-described embodiments, the present invention is not limited to such a disposable blood glucose measuring sensor 14 and the injection needle.

Further, although each blood glucose measurement sensor 14 is formed as a part of the sensor continuum 19, the blood glucose measurement sensor 14 may be a single type without being continuous. Further, in the above embodiment, the insulin syringe 12 is of the cartridge type, but the insulin syringe 12 of the present invention is not limited to such cartridge type.

Further, in the above-described embodiment, the sensor holder 18 is formed separately from the case body 1, and the separate sensor holder 18 is detachably accommodated in the sensor holder accommodating portion 15, and a flexible cord is also provided. Although the structure is such that it is electrically connected to the blood glucose measuring device main body 2 via 34, in the present invention, for example, the sensor holder 18 is integrally incorporated in the case main body 1, and the case main body is also incorporated. The structure may be electrically connected to the blood glucose measuring device main body 2 through an internal wiring such as a printed wiring in the inside 1.

In the case of the latter structure as described above, for example, only the blood glucose measurement sensor 14 used for measurement may be exposed on one end side of the inner surface of the case body 1.
