  The blood glucose meter 10 is configured such that the chip 12 is detachable with respect to the chip mounting part 16 provided at the front end. The cap 14 is configured to accommodate the chip 12 therein. FIG. 2 shows a state in which the chip mounting portion 16 is covered with a protective cap 18.

  The blood glucose meter 10 includes a control unit 40 that controls the blood glucose meter 10 as a whole, a storage unit 42 that stores various types of data, a power supply unit 44 formed of, for example, a button-type battery, and the like in a housing 20 formed of a hollow container. It has a measurement unit 46 that measures blood sugar levels and the like, and an audio output unit 48 that is a speaker that emits audio.

  The housing 20 is slightly elongated so that a person can hold it with one hand and easily press the button of the operation unit 24, and has a three-dimensional shape that is easy for a person to hold.

  On the upper surface of the blood glucose meter 10, a display unit 22 configured by, for example, a liquid crystal display is provided, and the display unit 22 displays input items, confirmation items, measurement results, and the like. Since the blood glucose meter 10 is formed in a small size so that it can be easily carried, the display unit 22 is also formed in a relatively small size.

  On the rear side of the display unit 22 and the back surface of the blood glucose meter 10, an operation unit 24 including a power button 30, a memory call button 32, a post-meal button 34, and a time setting button 36 formed by push buttons, for example, is provided. Accepts various operations from.

  The power button 30 is pressed by the user when the blood glucose meter 10 is turned on or off. The time setting button 36 is pressed by the user when setting the current time set in the blood glucose meter 10. The post-meal button 34 is pressed by the user when the blood glucose level is measured after the meal. The memory call button 32 is pressed by the user when confirming past measurement data stored in the blood glucose meter 10.

  An ejector operation element 28 that is movable in the front-rear direction is provided on the upper surface of the blood glucose meter 10 and behind the chip mounting part 16. The ejector operation element 28 is used in a state where the chip 12 is attached to the chip mounting part 16. The chip 12 is removed from the chip mounting portion 16 by being slid forward by a person.

  As shown in FIG. 3, the chip 12 has a substantially cylindrical shape, a base portion 50 formed in a disc shape, a nozzle portion 52 formed on one surface (front surface) of the base portion 50, and a base portion And a cylindrical portion 54 formed on the other surface (rear surface) of 50.

  The nozzle portion 52 is erected at the center of the base portion 50, and a sampling hole 56 penetrating in the axial direction is provided at the center portion. The tip portion of the nozzle portion 52 is formed in a tapered shape, and a concave groove 58 for facilitating the suction of the specimen is provided on the tip surface.

  Further, a plurality of (for example, four) engaging claws 60 made of elastic pieces are formed at the tip of the cylindrical portion 54 as arc-shaped convex portions that are continuous in the circumferential direction. A chevron convex portion 62 is provided to increase the angle.

  Inside the cylindrical portion 54, a test paper storage portion (not shown) communicating with the sampling hole 56 is provided. The test paper storage unit stores test paper for collecting blood and holding a predetermined amount of blood. The blood glucose meter 10 (FIG. 1) measures components in the blood by irradiating the blood held on the test paper with predetermined light.

[1-2. Control configuration of blood glucose meter]
As shown in FIG. 4, in the blood glucose meter 10, the control unit 40 controls each unit (the display unit 22, the operation unit 24, the storage unit 42, the power supply unit 44, the measurement unit 46, and the audio output unit 48).

  The control unit 40 is mainly configured by a CPU (Central Processing Unit) (not shown), and a predetermined program is stored from a storage unit 42 including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, a flash memory, and the like. Are read out and executed to control each unit to perform various processes such as a blood glucose level measurement process and a memory call process.

  The storage unit 42 stores, as character data, a plurality of types of text information to be displayed on the display unit 22 at each time point in the blood glucose level measurement standby stage, the blood glucose level measurement stage, the post-blood glucose level measurement stage, and the storage measurement result confirmation stage. doing. The storage unit 42 stores blood glucose level measurement data in association with either the pre-meal mode or the post-meal mode and the measurement date and time, for example, up to 500 latest data.

  The control unit 40 reads image data and character data from the storage unit 42 and outputs them to the display unit 22. In response to this, the display unit 22 displays an image or a character based on the image data or character data.

  Further, the control unit 40 reads out the audio data from the storage unit 42 and outputs it to the audio output unit 48. In response to this, the sound output unit 48 emits sound based on the sound data.

  When the operation is performed by being pressed by the user, the operation unit 24 converts the operation unit 24 into a predetermined operation signal and supplies the operation signal to the control unit 40. At this time, the control unit 40 executes various processes according to the operation signal.

  Further, the control unit 40 supplies a control signal to the measurement unit 46 to control it. In response to this, the measurement unit 46 sucks blood from the chip 12 to measure the blood glucose level, and transmits the measurement result to the control unit 40.

[1-3. Blood glucose level measurement method]
In this configuration, the cap 14 holds the chip 12 inside before the chip 12 is attached to the blood glucose meter 10.

  The user puts the cap 14 containing the chip 12 on the chip mounting portion 16 of the blood glucose meter 10 and pushes it to a predetermined depth. As a result, the chip 12 is held and fixed by the chip mounting portion 16, and the mounting operation of the chip 12 is completed. In this state, the blood sugar level in the blood as the sample can be measured.

  To collect blood, first, a fingertip is punctured with a dedicated puncture device, and a small amount (eg, about 0.3 to 1.5 μL) of blood is allowed to flow out from the puncture portion onto the skin. The tip of the chip 12 attached to the tip of the blood glucose meter 10 is brought into contact with a small amount of blood that has risen at the fingertip.

  As a result, the blood at the fingertip enters the inside of the chip 12, is sucked by capillary action, flows inward, and reaches the center of the test paper accommodated in the chip 12. The blood that has reached the test paper penetrates into the inside from the surface and spreads radially outward.

  Simultaneously with the development of the blood, the glucose in the blood and the reagent carried on the test paper start to react, and the color changes depending on the amount of glucose. For example, when glucose oxidase is used as a reagent, hydrogen peroxide and gluconic acid are produced, and a quinone dye can be colored by allowing peroxidase to act on the produced hydrogen peroxide. The measurement unit 46 can determine the blood sugar level by measuring (coloring) the colored pigment and quantitatively measuring the intensity (shading) of the coloration.

  When the chip 12 is discharged from the chip mounting portion 16 after the measurement is completed, the user puts the cap 14 that is empty inside the chip mounting portion 16 and slides the ejector operation element 28 forward. As a result, the blood glucose meter 10 operates the ejector mechanism provided inside the housing 20, pushes out the chip 12 from the chip mounting part 16, and separates it from the chip mounting part 16. Then, the user discards the cap 14 and the chip 12 stored in the cap 14 in a predetermined disposal container.

  Thus, the user can easily and quickly dispose of the chip 12 while maintaining safety without touching the chip 12.

[1-4. Blood glucose level measurement process]
Next, a specific processing procedure of the measurement process by the blood glucose meter 10 will be described in detail with reference to the flowcharts of FIGS.

  When the power button 30 is pressed by the user, the control unit 40 of the blood glucose meter 10 starts the blood sugar level measurement processing procedure RT1 by reading out and executing the blood sugar level measurement program from the storage unit 42, and proceeds to step SP1. .

  In step SP1, the control unit 40 randomly reads one piece of information from the information related to blood glucose level measurement stored in the storage unit 42, displays it on the display unit 22, and proceeds to the next step SP2.

  Examples of information relating to blood glucose level measurement include “don't leave with a chip attached”, “massage of fingertips on a cold day”, and “do not add blood”.

  Here, “do not leave the chip attached” means that if the chip 12 is left on the blood glucose meter 10 for a long time, normal measurement may not be performed. It prompts you to start measuring quickly.

  Also, “Massage of fingertips on cold days” means that it is difficult for blood to come out from the user on days with low temperatures. It encourages you to do.

  “Do not add blood” means that if blood is once collected from the chip 12 and then added, the normal measurement result may not be obtained. It is urged to collect only a certain amount of blood at a time.

  The blood glucose meter 10 cannot determine whether or not the user has added blood, and cannot give a measurement error even if blood is added. By presenting, it is possible to avoid forgetting the measurement method.

  In step SP2, the control unit 40 determines whether or not the chip 12 is mounted on the chip mounting unit 16 of the blood glucose meter 10.

  If a negative result is obtained in step SP2, this indicates that the measurement is not started because the chip 12 is not yet attached to the blood glucose meter 10, and at this time, the control unit 40 moves to step SP3, and the memory call button It is determined whether or not 32 is pressed by the user.

  If an affirmative result is obtained in step SP3, this indicates that the user is going to confirm the past measurement data stored in the storage unit 42 because the memory recall button 32 has been pressed. The unit 40 moves to step SP4 and starts a storage call processing procedure SRT1 (described later).

  On the other hand, if a negative result is obtained in step SP3, this means that the user has not attempted to confirm the past measurement data stored in the storage unit 42 because the memory recall button 32 has not been pressed. At this time, the control unit 40 moves to step SP5, and determines whether or not a certain time (for example, 1 minute) has elapsed since the display of the blood glucose level measurement information in step SP1.

  If a negative result is obtained in step SP5, this means that the information regarding the blood glucose level measurement currently being displayed continues to be displayed since a certain time has not elapsed since the information regarding the blood glucose level measurement has been displayed. At this time, the control unit 40 returns to step SP2 and determines whether or not the chip 12 is mounted on the chip mounting unit 16 of the blood glucose meter 10.

  On the other hand, if an affirmative result is obtained in step SP5, this means that the display of information relating to blood glucose level measurement has been switched since a certain period of time has elapsed since the information relating to the currently displayed blood glucose level measurement has been displayed. The control unit 40 returns to step SP1, reads out one piece of information from the information relating to blood glucose level measurement stored in the storage unit 42 at random, displays it on the display unit 22, and proceeds to the next step SP2.

  As described above, the blood glucose meter 10 operates the blood glucose meter to correctly and reliably measure the blood glucose level in the blood glucose level measurement in the blood glucose level measurement standby stage from when the power is turned on to when the blood glucose level measurement is started. By presenting the user with useful information (advice) related to blood glucose level measurement, including methods, operating procedures, points to be noted regarding the user's body, etc., the correct blood glucose level will be ensured in subsequent blood glucose meter measurements. Can be measured.

  In addition, the blood glucose meter 10 can present a plurality of pieces of information to the user without the user operating the blood glucose meter 10 by switching the information regarding the blood glucose level measurement at random intervals and displaying it at random.

  On the other hand, if an affirmative result is obtained in step SP2, this indicates that the measurement is started because the chip 12 is attached to the blood glucose meter 10. At this time, the control unit 40 moves to step SP6 and the display unit 22 indicates “ By displaying “OK”, the user is prompted to suck blood into the chip 12, and the process proceeds to step SP7.

  In step SP7, the control unit 40 determines whether or not the user has pressed the post-meal button 34. If an affirmative result is obtained here, this indicates that the user is performing blood glucose level measurement after meals. At this time, the control unit 40 moves to step SP8 and performs blood glucose level measurement after meals. The “post-meal mode” shown is set in the storage unit 42. The control unit 40 stores the measurement result of the blood glucose level measured in the following processing in the storage unit 42 in association with the “post-meal mode”.

  On the other hand, if a negative result is obtained in step SP7, this indicates that the user is measuring the blood sugar level before eating. At this time, the control unit 40 moves to step SP9 and measures the blood sugar level before eating. “Pre-meal mode” indicating this is set in the storage unit 42. The control unit 40 stores the measurement result of the blood glucose level measured in the following processing in the storage unit 42 in association with the “pre-meal mode”.

  In step SP10, the control unit 40 controls the measurement unit 46 to start measuring the blood sugar level, and proceeds to the next step SP11. In step SP11, the control unit 40 reads one piece of information at random from information on health management (therapy) stored in the storage unit 42, displays the information on the display unit 22, and proceeds to the next step SP12.

  Examples of information related to health management include “Periodically check ophthalmology”, “Let's keep proper exercise”, “Eating meals in the eighth quarter”, and the like.

  Here, “regular ophthalmic examination” means that a diabetic patient tends to develop complications such as diabetic retinopathy, and therefore promotes ophthalmic examination.

  In step SP12, the control unit 40 determines whether or not the measurement in the measurement unit 46 is finished. If a negative result is obtained here, this is still being measured for the blood glucose level, and the control unit 40 waits for the end of the measurement. Incidentally, this blood glucose level measurement is completed in about 8 seconds.

  As described above, the blood glucose meter 10 is useful for health management including precautions in daily life for managing diabetes at the time of blood glucose measurement, which is a state from the start to the end of blood glucose measurement. By presenting information (advice) to the user, it is possible to encourage attention to health care in daily life regardless of whether the measurement result is good or bad.

  Moreover, the blood glucose meter 10 can provide useful information to the user by effectively utilizing the waiting time while the user is waiting for the completion of the measurement.

  On the other hand, if an affirmative result is obtained in step SP12, since the blood glucose level measurement is completed, the control unit 40 moves to step SP13 and stores the blood glucose level measurement result together with the measurement date and time in the storage unit.

  At this time, the control unit 40 stores the measurement result in the storage unit 42 in association with the “post-meal mode” or “pre-meal mode” set in step SP8 or SP9, so that the blood glucose level measurement of this time is performed after the meal. It is remembered whether it was a dish or something that was done before meals.

  In step SP14, the control unit 40 displays the measured blood sugar level on the display unit 22, and proceeds to step SP15.

  In step SP15, the control unit 40 determines whether or not the measured blood glucose level is below a predetermined low blood glucose threshold (for example, 70 gm / dL). If an affirmative result is obtained here, this means that the measurement result is hypoglycemia. At this time, the control unit 40 moves to step SP16, and a plurality of types of hypoglycemia countermeasures stored in the storage unit 42 are stored. One piece of information is read at random from the information on the display, displayed on the display unit 22, and the process proceeds to the next step SP17.

  Examples of information relating to coping with hypoglycemia include “take glucose” or “go to the hospital in case of malfunction”. In the case of hypoglycemia, the user may have a reduced judgment. Therefore, immediately after displaying the measurement result, the control unit 40 displays information on coping with hypoglycemia and prompts the patient to pay attention.

  In step SP17, the control unit 40 determines whether or not a certain time (for example, 1 minute) has elapsed since the information related to coping with hypoglycemia was displayed in step SP16.

  The control unit 40 waits until a predetermined time elapses in step SP17, and after the predetermined time elapses, moves to step SP26, ends the blood sugar level measurement processing procedure RT1, and shuts off the power.

  On the other hand, if a negative result is obtained in step SP15, this indicates that the measurement result is not hypoglycemia. At this time, the control unit 40 moves to step SP18 and displays the measured blood glucose level on the display unit 22. The process waits for 1 minute and proceeds to step SP19 after 1 minute has elapsed.

  In step SP19, the control unit 40 determines whether or not the measured blood glucose level exceeds a predetermined hyperglycemia threshold (for example, 130 gm / dL). If a negative result is obtained here, this indicates that the measurement result is a normal value, and at this time, the control unit 40 proceeds to step SP20.

  In step SP20, the control unit 40 randomly reads one piece of information from the health management information stored in the storage unit 42, displays it on the display unit 22, and proceeds to the next step SP24.

  Examples of information relating to health management include “Periodic examinations regularly”, “Observation and care of feet” and “Beware of hypoglycemia when drinking”.

  As described above, the blood glucose meter 10 deviates from the normal value when the blood glucose level measurement result is a normal value after the blood glucose level measurement is completed after the blood glucose level measurement is completed and the measured blood glucose level is displayed for a certain period of time. Information that calls attention to blood glucose level management is not displayed as in the case of low blood sugar and high blood glucose, and information that is useful for health management in daily life is displayed.

  On the other hand, if a positive result is obtained in step SP19, this indicates that the measurement result is hyperglycemia, and at this time, the control unit 40 proceeds to step SP21.

  In step SP21, the control unit 40 determines whether or not the pre-meal mode is set in step SP9 (FIG. 5).

  If a negative result is obtained in step SP21, this indicates that the current measurement result is obtained after a meal, and at this time, the control unit 40 proceeds to step SP22.

  In step SP22, the control unit 40 reads one piece of information randomly from the information on postprandial hyperglycemia stored in the storage unit 42, displays the information on the display unit 22, and proceeds to the next step SP24.

  Examples of information related to postprandial hyperglycemia include “Let's exercise moderate exercise” and “Eating at the eighth minute”.

  On the other hand, if an affirmative result is obtained in step SP21, this indicates that the current measurement result is obtained before eating (on an empty stomach), and at this time, the control unit 40 proceeds to step SP23.

  In step SP23, the control unit 40 reads one piece of information randomly from the information on fasting hyperglycemia stored in the storage unit 42, displays the information on the display unit 22, and proceeds to the next step SP24.

  Information on fasting hyperglycemia includes, for example, “Let's refrain from snacking” and “Don't forget to take medicine?”

  Here, generally, the blood glucose level after a meal rises more than before a meal. Therefore, when the blood glucose meter 10 determines that the blood sugar level is high after blood sugar level measurement and the blood sugar level is high before the meal, the blood glucose meter 10 includes a method for dealing with fasting high blood sugar such as refraining from snacking. Useful information about hyperglycemia is presented to the user.

  On the other hand, the blood glucose meter 10 is useful for postprandial hyperglycemia, including measures for postprandial hyperglycemia, such as prompting exercise, when it is determined that the blood glucose level is high after blood glucose measurement and the postprandial blood glucose level is high By presenting such information to the user, it is possible to prompt the user to pay attention to the future according to the measurement result after or after the meal.

  Thus, the blood glucose meter 10 presents the user with useful information according to the measurement result of normal blood glucose level, low blood glucose level, postprandial high blood glucose level, or fasting high blood glucose level after blood glucose level measurement. It is made like that.

  In step SP24, the control unit 40 determines whether or not the user has pressed the power button 30 continuously for a predetermined time. If a positive result is obtained here, this indicates that the user is about to end use of the blood glucose meter 10, and at this time, the control unit 40 moves to step SP26 and ends the blood glucose level measurement processing procedure RT1. And turn off the power.

  On the other hand, if a negative result is obtained in step SP24, the control unit 40 waits until a predetermined time (for example, 2 minutes) elapses in step SP25, and after the predetermined time elapses, moves to step SP26, and the blood glucose level measurement processing procedure RT1. And turn off the power.

  As described above, the blood glucose meter 10 is in a state where the chip 12 is not sucking blood, and a state in which any button of the operation unit 24 is not operated by the user (that is, a state in which nothing is operated) is, for example, When it lasts for 2 minutes, the power is automatically turned off.

  Incidentally, the blood glucose meter 10 is automatically turned off when no operation continues for 2 minutes, except in step SP25.

[1-5. Memory recall processing]
When the control unit 40 proceeds to step SP4 of the blood glucose level measurement processing procedure RT1 (FIG. 5), the storage calling program is read from the storage unit 42 and executed, thereby starting the storage calling processing procedure SRT1 shown in FIG. Control goes to step SP31.

  In step SP31, the control unit 40 reads the latest measurement data from the measurement data stored in the storage unit 42, displays the latest measurement data on the display unit 22, and proceeds to the next step SP32. Incidentally, when a plurality of measurement data are stored in the storage unit 42, the control unit 40 reads out the measurement data whose measurement date is one by one every time the storage call button 32 is pressed once, and displays it on the display unit 22. It is made to do.

  In step SP32, the control unit 40 determines whether or not an operation is performed by the user (that is, whether the chip 12 is mounted on the chip mounting unit 16 of the blood glucose meter 10 or any button of the operation unit 24 is operated). judge.

  If a positive result is obtained in step SP32, this means that the user ends the storage call processing procedure SRT1 and starts measurement, or the next stored in the storage unit 42 (the measurement date is one older). This indicates that the measurement data is to be confirmed. At this time, the control unit 40 proceeds to step SP39, ends the memory call processing procedure SRT1, and proceeds to step SP5 of the blood glucose level measurement processing procedure RT1 (FIG. 5).

  On the other hand, if a negative result is obtained in step SP32, this indicates that the user has confirmed the measurement result and has not performed an operation. At this time, the control unit 40 moves to step SP33 and displays the measurement result. Waiting for 1 minute while displayed on the unit 22, the process proceeds to step SP34 after 1 minute has elapsed.

  In step SP34, the control unit 40 reads the measurement data for the past week from the storage unit 42, and calculates an average blood glucose level that is an average value of the measurement data.

  In step SP34, the control unit 40 determines whether or not the calculated average blood glucose level exceeds a predetermined average hyperglycemia threshold (for example, 130 gm / dL). If a negative result is obtained here, this indicates that the average value of the measurement data for the past one week was a normal value, and at this time, the control unit 40 proceeds to step SP36.

  In step SP36, the control unit 40 reads out one piece of information from the information related to health management stored in the storage unit 42 at random, displays the information on the display unit 22, and proceeds to the next step SP38.

  Examples of information relating to health management include “Periodic examinations regularly”, “Observation and care of feet” and “Beware of hypoglycemia when drinking”.

  As described above, the blood glucose meter 10 is configured to check the past measurement data stored in the storage unit 42. When the average blood glucose level is a normal value in the storage measurement result confirmation stage, the blood glucose meter 10 In this way, information that calls attention to blood glucose level management is not displayed, and information useful for health management in daily life is displayed.

  On the other hand, if an affirmative result is obtained in step SP35, this means that the average blood glucose level is hyperglycemia, and at least the last week has been chronically hyperglycemia. At this time, the control unit 40 performs step SP37. Move on.

  In step SP37, the control unit 40 randomly reads one piece of information from the information related to hyperglycemia stored in the storage unit 42, displays the information on the display unit 22, and proceeds to the next step SP38.

  Information on hyperglycemia includes, for example, “Let's exercise moderately”, “Eating meals in the eighth minute”, “Consult at the next visit”, and the like.

  In this way, the blood glucose meter 10 presents useful information on hyperglycemia to the user, including measures to cope with hyperglycemia such as refraining from eating when the average blood glucose level is hyperglycemia in the memory measurement result confirmation stage. By doing so, it is possible to prompt the user to pay attention in the future according to the average value of the measurement results.

  In addition, the blood glucose meter 10 displays a message “Consult at the next visit” on the display unit 22 because the blood glucose meter is chronically hyperglycemic in the last week, not the result of one measurement. It is also made to encourage.

  In step SP38, the control unit 40 determines whether or not a predetermined time (for example, 1 minute) has elapsed since the information related to health management was displayed in step SP36 or the information related to hyperglycemia was displayed in step SP37.

  In step SP38, the control unit 40 waits until a predetermined time elapses.
