The problem in the above conventional example is that the measured value becomes inappropriate due to long-term use. That is, in this type of measuring apparatus, as described above, the sensor is inserted into the sensor insertion portion several times a day and is inserted more than 1000 times a year. Dirt adheres to and accumulates on the connector provided in the portion, and as a result, the contact resistance at the connector portion increases, thereby making the measured value inappropriate.
Therefore, an object of the present invention is to suppress inappropriate measurement values due to long-term use.

A measurement unit connected to the sensor insertion unit, a sensor insertion number counting unit for counting the number of sensor insertions into the sensor insertion unit, and a control unit connected to the sensor insertion number counting unit and the measurement unit. Since the display unit is connected to the control unit, inappropriate measurement values due to long-term use can be suppressed.
That is, in the present invention, the number of times the sensor is inserted into the sensor insertion section is counted by the sensor insertion count section of the electric circuit, and when this count exceeds a predetermined value, a display prompting insertion of the inspection sensor is displayed on the display section. Since it is configured, the user sees this display and inserts the inspection sensor into the sensor insertion portion. Then, by performing this insertion, it is possible to check the dirt state in the sensor insertion portion, and therefore it is possible to prevent improper measurement from being continuously performed without knowing this dirt state. .

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an external view of the measuring device 30 according to the present invention as viewed from the front, and FIG. 2 is a perspective view of the measuring device 30. 1 and 2 both show a state where the sensor is mounted.

Specifically, the main body case 3 is a rectangular parallelepiped, the display unit 1 is provided on the upper surface, and the sensor insertion unit 2 is provided on the outer periphery. Then, a blood glucose level sensor 4 which is an example of a blood analysis sensor for analyzing blood is inserted into the sensor insertion unit 2 as an example of a sensor, and blood glucose level and the like are measured and analyzed in this inserted state. It has become.

  In the state of FIG. 1, the display unit 1 displays a measurement date and time (in the example of FIG. 1, 11:11 am on December 12) and a measurement value such as a blood glucose level at the measurement date and time (in FIG. 1 In the example, 123 mg / dl is indicated).

Now, the blood glucose level sensor will be described with reference to FIG. FIG. 3 is a plan view of the blood glucose level sensor 4. As shown in FIG. 3, the blood glucose level sensor 4 has a substantially rectangular shape and collects blood exuded from the skin on the left end side in FIG. 3 (left side in FIG. 3) and collects the reagent in the blood glucose level sensor 4. A blood glucose level sensor 4 includes a detection unit 5 that reacts to extract an electrochemical signal and a connection terminal 6 (consisting of a plurality of terminals) derived from a plurality of detection electrodes (not shown) constituting the detection unit. Is arranged on the right end side (right side in FIG. 3).
Next, a sensor insertion part to which the blood sugar level sensor 4 is attached will be described with reference to FIGS. FIG. 4 is a cross-sectional view of a state in which the blood glucose level sensor 4 is attached to the sensor insertion portion of the main body case 3. FIG. 5 is an enlarged cross-sectional view of a main part of the connector 7 (dotted line portion in FIG. 4) which is a contact portion with the connection terminal 6 of the blood glucose level sensor 4 in the sensor insertion portion.
As shown in FIGS. 4 and 5, the body case 3 into which the blood glucose level sensor 4 is inserted is provided with a connector 7 formed of a spring terminal on the inside thereof, and comes into contact with the connection terminal 6 of the sensor 4. The connector 7 of the sensor insertion portion is elastically deformed and electrically connected, whereby the electrochemical signal detected by the blood glucose level sensor 4 is transferred to the electric circuit 8 (see FIG. 7) in the main body case 3. It is configured to be transmitted via the connector 7.
The electric circuit 8 measures the blood glucose level based on the signal from the blood glucose level sensor 4 input by the measurement unit 9, and the blood glucose level that is the measured value on the display unit 1 (see FIG. 1) of the main body case 3 via the control unit 10. Display the value.
Next, control of the measuring apparatus 30 of the present invention will be described below with reference to FIG.
FIG. 7 is a control block diagram of the electric circuit 8 and its surroundings in the measuring apparatus 30 of the present invention.
In FIG. 7, the electric circuit 8 has a sensor insertion count unit 11 connected to the sensor insertion unit, and the sensor insertion count unit 11 is inserted each time the blood glucose level sensor 4 is inserted into the sensor insertion unit 2. Counts the number of insertions of the blood glucose level sensor 4. The counted insertion number data is stored in the sensor insertion number storage unit 12.

  The number of counts counted by the sensor insertion number counting unit 11 is held while a battery 21 (not shown) built in the measuring device 30 holds a predetermined voltage. In this case, the sensor insertion count storage unit 12 is configured by a nonvolatile memory such as an EEPROM or a flash memory, so that the blood sugar level to the sensor insertion unit 2 can be changed even when the battery is replaced. The insertion number data of the sensor 4 is held in the sensor insertion number storage unit 12.

As will be described in detail later, when either the count number of the sensor insertion count unit 11 or the insertion number data stored in the sensor insertion number storage unit 12 exceeds a predetermined value (for example, 1000 times), the control unit 10 Then, a display (refer to FIGS. 13 and 14) for prompting insertion of the inspection sensor 13 (refer to FIG. 6) into the sensor insertion portion 2 is performed on the display unit 1.
At this time, the buzzer 14 used as an example of the alarm means issues an alarm prompting replacement.

  Next, the inspection sensor 13 will be described. The inspection sensor 13 shown in FIG. 6 has a rectangular shape and is longer than the blood glucose level sensor 4 shown in FIG. 3, and therefore has a large surface area. In addition, on the left end side, an indication 15 “CHECK” indicating inspection is provided, and on the right end side, eight connection terminals 16 are provided. The connection terminal 16 of the inspection sensor 13 and the connection terminal 6 of the blood glucose level sensor 4 shown in FIG. 3 have the same arrangement and size, but the contact terminal 16 of the inspection sensor 13 is shown in FIG. In this way, adjacent connection terminals 16 are short-circuited via two resistors 17 respectively. The inspection sensor can be changed not only in size but also in shape.

Here, the same number of terminals as the blood glucose level sensor 4 are provided, but a terminal for inspection may be provided separately. It depends on the mode of the connector which is the connection terminal on the main body side of the measuring device 30.
The usage of the inspection sensor 13 will be described in detail later.

As shown in FIG. 1, a tool image 18 and a bar image 19 urging inspection are provided at the lower left of the display unit 1 as a notice message informing the inspection time.
Hereinafter, the display content of the display part 1 is demonstrated using FIGS. 9-20. When the number of times the blood glucose level sensor 4 is inserted into the sensor insertion portion 2 does not exceed a predetermined number 1 (for example, 300 times), both the tool image 18 and the bar image 19 are blank as shown in FIG. Yes.
Thereafter, when the number of insertions of the blood glucose level sensor 4 into the sensor insertion part 2 exceeds a predetermined number 1 (300 times), the tool image 18 is white as shown in FIG. One-third of 19 is in a colored state.

  When the blood sugar level sensor 4 is inserted into the sensor insertion portion 2 more than a predetermined number 2 (for example, 600 times), the tool image 18 is white, but the bar image 19 is Two-thirds are colored (see FIG. 11).

  Further, when the blood sugar level sensor 4 is inserted into the sensor insertion part 2 more than a predetermined number 3 (for example, 1000 times), both the tool image 18 and the bar image 19 are colored (see FIG. 12), and the sensor is inserted. An inspection message (see FIGS. 13 and 14) prompting insertion of the inspection sensor 13 into the section 2 appears. At this time, as described above, an alarm (inspection message) that prompts inspection by the buzzer 14 (see FIG. 7) is also issued.

Further, at this time, the blood glucose level display portion shown in FIG. 1, that is, the measured blood glucose level (showing 123: 11 in FIG. 1) at the measurement date and time (showing 11:11 am on December 12, in FIG. 1) is shown. The inspection messages shown in FIGS. 13 and 14 are alternately displayed in the displayed portion.
In FIG. 13, before the inspection sensor 13 is inserted into the sensor insertion portion 2, the state after the inspection sensor 13 is inserted is displayed in FIG. The necessity of inserting the illustrated inspection sensor 13 into the sensor insertion portion 2 will be visually recognized.

At this time, when the inspection sensor 13 is attached to the sensor insertion portion 2 (see FIGS. 1 and 2) of the main body case 3, the measuring device 30 enters an inspection mode state in which an inspection operation is performed.
As shown in FIG. 8, the inspection sensor 13 has a structure in which adjacent connection terminals are short-circuited by two resistors, and the inspection processing unit that performs the inspection operation has a current flowing at this time. Is measured by the measuring unit 9 of the electric circuit 8. That is, the inspection processing unit includes the measurement unit 9 and the control unit 10 of the electric circuit 8. Further, in cooperation with the inspection sensor 13, the operation state of the sensor insertion portion 2 of the measuring device 30 is inspected.
Note that during this measurement, instead of displaying a message prompting the insertion of the inspection sensor 13 shown in FIGS. 13 and 14, as shown in FIGS. 15 to 17, broken lines are sequentially displayed around the display “CHECK”. In the state of enclosing in accordance with the progress of the inspection, a display indicating that the inspection is in progress is displayed, and when the inspection process is completed, as shown in FIG.
When the inspection result is determined that the inspection processing operation determines that the connection terminal 7 of the sensor insertion section 2 is very dirty and appropriate measurement is impossible by this inspection processing operation, as shown in FIG. A display with “×” on the main body case 3 and a display with “NEW” on the main body case 3 appear on the display unit 1 and a replacement alarm is issued by the buzzer 14.
At this time, the user replaces the measuring device 30 with a new one.
Further, if the connection terminal 7 of the sensor insertion portion 2 is not dirty and is normal in the above inspection, the display “CHECK” shown in FIG. 19 appears on the display portion 1, and this CHECK is displayed at the next moment. However, as shown in FIG. 20, the display changes to “OK”. In this state, the electric circuit 8 shown in FIG. 7 can reset the values of the sensor insertion number counting unit 11 and the sensor insertion number storage unit 12 by the reset unit 20.

  Further, here, a case where the display is displayed in two colors of black and white is described, but the display is not limited to this, and the display unit 1 may be a color LCD, a color organic EL, or the like.

Next, the operation of the measuring apparatus of the present invention will be described below with reference to FIGS.
First, FIG. 21 shows the contents of checking the number of insertions of the sensor according to the present invention in the operation of measuring the normal blood glucose level.

In step S1, the blood glucose level sensor 4 is attached to the sensor insertion portion 2 (see FIG. 1). Thereby, the measurement preparation of the measuring apparatus 30 is performed. In step S2, the insertion of the blood glucose level sensor 4 is detected, and the sensor insertion number counting unit 11 (see FIG. 7) counts the number of sensor insertions. Further, this count value is stored and held in the sensor insertion number storage unit 12 (see FIG. 7).
In step S3, the count value is compared with a preset number of regular inspections (for example, 1000 times). If the count value has reached the number of periodic inspections, the process proceeds to step S4, and the inspection message (see FIGS. 13 and 14) is alternately displayed in blinking and the notice message in FIG. 12 to prompt the user for inspection.
At this time, the buzzer 14 (see FIG. 7), which is an alarm means, can also sound (step S5). Moreover, in this state, as shown to step S6, use of a measuring apparatus is stopped. That is, the measurement operation is prohibited until the inspection operation is completed. Control goes to step S7.
In step S7, the blood glucose level sensor 4 is extracted from the sensor insertion portion 2, and in the subsequent step S8, the sleep state is entered, and a standby state is waited for insertion of the inspection sensor 13. At this time, the display is only the notice message of FIG.
Next, the process proceeds to step S9 (see FIG. 22). In step S3, when the count value counted by the sensor insertion number counting unit has not reached the number of periodic inspections, the process proceeds to step S31. In step S31, the count value is compared with a first predetermined number of times. If the count value has reached the first predetermined number of times (for example, the above-mentioned 600 times), the process proceeds to step S32, and if not, the process proceeds to step S51.

In step S32, the notice message shown in FIG. In this case, the measurement operation of the measurement device 30 is not stopped, and the user is notified that the inspection time is approaching.
Moving to step S33, a normal blood sugar level measurement operation is executed. In step S51 (when the count value has not reached the first predetermined number in step S31), the count value is compared with the second predetermined number. If the count value has reached the second predetermined number of times (for example, the above-mentioned 300 times), the process proceeds to step S52, and the notice message of FIG. 10 is displayed. If the count value has not reached the second predetermined number of times, the process proceeds to step S53, and the notice message (display 1) in FIG. 9 is displayed.
Since measurement is possible in steps S52 and S53, the process proceeds to step S33, and a normal measurement operation is performed. After the measurement operation in step S33, in step S34, the blood glucose level sensor 4 is removed and discarded. Next, in step S35, a sleep state is entered and the main power supply is turned off. After the display in step S35, the process proceeds to step S1 to enter a standby state for waiting for the blood glucose level sensor to be mounted.

  In step S8, after entering the waiting state for waiting for the insertion of the inspection sensor 13, the process proceeds to step S9 (see FIG. 22), and the sensor is inserted. Thereby, the display in the sleep state is changed to the display in the measurement standby state (see FIG. 1).

In step S10, it is determined whether the sensor attached to the sensor insertion unit 2 is the inspection sensor 13. If it is not an inspection sensor, the process proceeds to step 1 (see FIG. 21) and the above-described processing is executed. If it is the inspection sensor 13, the process proceeds to step S <b> 11, and a message indicating that the inspection is starting (see FIGS. 15 to 17) is displayed on the display unit 1 (see FIG. 1).
In the next step S12, the resistance between the connection terminals 16 (terminals 1 to 8 in FIG. 8) is reduced by the cooperation of the inspection sensor 13, the measuring unit 9 and the control unit 10 of the measuring device 30, and the sensor insertion unit 2 of the measuring device 30. Measurement / inspection is performed via a connector connected to the connection terminal 16 in the interior of the device to check the operation state.

Here, as shown in FIG. 8, the inspection sensor 13 has a known resistance mounted between the connection terminals in advance, and compares the known resistance value with the actually measured resistance value to determine a resistance error. If it is within the range, it is determined to be OK. Here, since two resistance values of 75 kΩ are arranged in series, it is determined that the total is in the range of 150 kΩ ± 10 kΩ.
However, although an example in which two 75 kΩ are arranged in series is shown here, the numerical values are not limited to these, and 1 MΩ or less is possible. It differs depending on the internal circuit of the measurement unit and the level of the signal to be detected.

  If the inspection is OK in step S12, the process proceeds to step S13, and an inspection completion display (see FIG. 19) and an inspection OK display (see FIG. 20) are alternately displayed on the display unit 1, and the process proceeds to step S14. In step S14, the count value of the sensor insertion number stored in the sensor insertion number storage unit is reset, and the process returns to step 1 (see FIG. 21).

If it is an inspection error in step S12, the process proceeds to step S15, and a message (see FIG. 18) notifying the failure of the measuring device is displayed on the display unit 1 to notify the user of the failure of the measuring device 30.
In step S16, the buzzer 14 which is an alarm means is sounded and notified audibly.
In step S17, the use of the measuring device 30 is also prohibited, and the processing of the measuring device 30 ends.

  As described above, the present invention includes a main body case having a display portion and a sensor insertion portion, and an electric circuit provided in the main body case and connected to the display portion and the sensor insertion portion. A measurement unit connected to the sensor insertion unit, a sensor insertion number counting unit for counting the number of sensor insertions into the sensor insertion unit, and a control unit connected to the sensor insertion number counting unit and the measurement unit. Since the display unit is connected to the control unit, inappropriate measurement values due to long-term use can be suppressed.

That is, in the present invention, the number of sensor insertions in the sensor insertion part is counted by the sensor insertion number counting part of the control part, and when this count number exceeds a predetermined value, a display prompting the display part to insert the inspection sensor is displayed. Since it is configured to perform, the user sees this display and inserts the inspection sensor into the sensor insertion portion. And by performing this insertion, it is possible to check and confirm the malfunctioning state of the measuring device due to dirt in the sensor insertion part, so this user is inappropriate without knowing the malfunctioning state of the measuring device due to dirt, etc. Therefore, continuous measurement can be prevented.

    Therefore, widespread use is expected to increase the reliability of various measuring devices.
