Next, the flow of the operation of the blood glucose meter 101 of the post-meal button specification will be described with reference to Figs. 5 to 14(a), 14(b), and 14(c).

FIG. 5 is a flowchart showing the flow of sleep processing of the blood glucose meter 101.

When the processing is started (S501), the input/output control unit 310 of the blood glucose meter 101 blocks power supply to a device (device) having a large power consumption such as an A/D converter, a display unit 309, or an LED (not shown), and becomes A sleep mode that operates at a low frequency clock of several hundred kHz to several MHz. However, the operation of the operation unit 308 and the state of the micro switch are detected by the input/output control unit 310 (S502).

The input/output control unit 310 determines whether the operated operation button 104 is a long press of the up direction button 105, that is, whether the power button has been pressed and whether the micro switch has been turned on (S503).

When the power button is pressed or the micro switch is turned on (YES in S503), the input/output control unit 310 executes the main process (S504), and thereafter ends the process (S505).

If the power button is not pressed and the micro switch is not turned on (NO in S503), the input/output control unit 310 does not perform any operation. The process ends (S505). This sleep processing is a loop operation that is repeated again and again after the processing ends.

FIG. 6 is a flowchart showing the flow of main processing of the blood glucose meter 101. Fig. 6 shows the details of step S504 of Fig. 5.

When the processing is started (S601), the input/output control unit 310 executes a predetermined initialization process (S602), and then displays the main menu on the display unit 309 (S603), and waits for the operation of the operation unit 308 (S604).

When the operation content obtained from the operation button 104 is the blood glucose level measurement (YES in S605), the input/output control unit 310 executes the blood sugar level measurement process (S606), and thereafter displays the main menu again (S603).

When the operation content obtained from the operation button 104 is not the blood glucose level measurement (NO in S605), and the operation content is an instruction to display the history of the past blood glucose level (YES in S607), the input/output control unit 310 executes The history display processing (S608), and thereafter the main menu is displayed again (S603).

When the operation content obtained from the operation button 104 is not an instruction to display the history of the past blood sugar level (NO in S607), and the operation content is an instruction to display a photo (YES in S609), the input/output control unit 310 executes The photo display processing (S610), and thereafter the main menu is displayed again (S603).

If the operation content obtained from the operation button 104 is not an instruction to display a photo (NO in S609), and the operation content is an instruction to take a photo (Yes in S611), the input/output control unit 310 performs a photo shooting process (S612). ), and then the main menu is displayed again (S603).

If the operation content obtained from the operation button 104 is not an instruction to take a picture (NO in S611), and the operation content is an instruction to perform various settings (NO in S613), the input/output control unit 310 executes various setting processes ( S614), the main menu is displayed again (S603).

If the operation content obtained from the operation button 104 is not an instruction to perform various settings, and the operation content is an instruction to turn off the power (YES in S613), the input/output control unit 310 performs power-off processing (S615), and ends. A series of processes (S616).

FIG. 7 is a flowchart showing a detailed flow of blood sugar level measurement processing in step S606 of FIG. 6.

When the process is started (S701), the input/output control unit 310 first starts the postprandial button detection process (S702) which will be described later in FIG. Next, the input/output control unit 310 displays a "wafer mounting instruction" screen on the display unit 309, instructs the wafer for measuring the blood sugar level to be attached to the optical measurement unit 109 (S703), and waits for the wafer to be mounted by the blood sugar level measuring unit 301. (S704).

After the wafer is mounted on the optical measurement unit 109, the input/output control unit 310 displays a "blood drip instruction" screen on the display unit 309, instructs the blood to be dropped onto the wafer (S705), and waits for blood by the blood sugar level measuring unit 301. Drip (S706).

When blood is dropped onto the wafer, the blood sugar level measuring unit 301 executes blood sugar level measuring processing (S707). The input/output control unit 310 receives the blood glucose level measured by the blood glucose level measuring unit 301, displays the blood glucose level on the display unit 309 (S708), and waits for the operation of the operation unit 308 (S709).

When the decision button 107 is pressed, the input/output control unit 310 ends the detection process of the postprandial button (S710), and additionally records the measured blood glucose level, the date and time of measuring the blood glucose level, and the postprandial flag to the blood glucose level table. 307 (S711), and ends a series of processing (S712).

Fig. 8 is a flowchart showing the flow of post-meal button detection processing. The process starts from step S702 of Fig. 7 until step S710 ends.

When the processing is started (S801), the input/output control unit 310 initializes the internal post-meal flag (not shown) to logical "false" (S802), and waits for the operation of the post-meal button (S803). Next, the input/output control unit 310 confirms whether or not the post-meal button is pressed, that is, whether or not the decision button 107 is long pressed (S804).

If the post-meal button is not pressed (NO in S804), the input/output control unit 310 returns to the step S803 to wait for the operation of the post-meal button.

When the post-meal button is pressed (YES in S804), the input/output control unit 310 sets the internal post-meal flag to "true" (S805), and ends the series of processes (S806).

That is, the internal post-meal flag is latched as the post-meal button has been pressed. Between steps S702 to S710 of FIG. 7, as long as the post-meal button is pressed once, the internal post-meal flag is converted into logical "true", and the internal post-meal flag is transferred to the blood glucose value table 307 in step S711. Post-meal flag bar.

Next, the flow of the history display processing of step S608 of Fig. 6 will be described with reference to Figs. 9, 10, 11, 12, and 13. In the history display processing, the input/output control unit 310 uses a natural number of pointers i. Record indicator i Indicates the i-th record of the blood glucose value table 307.

FIG. 9 is a flowchart showing the flow of history display processing.

When the processing is started (S901), the input/output control unit 310 first sets the recording index i to the last record of the blood glucose level table 307 (S902).

Then there is the loop processing.

Next, the input/output control unit 310 checks the date and time column of the i-th record of the blood glucose level table 307, and confirms whether or not the i-th record is a record measured between 21 o'clock and 6 am, that is, whether the i-th record is late at night. The record of the measured value (hereinafter referred to as "deep night recording") (S903).

When the i-th record is the late-night recording (Yes in S903), the input/output control unit 310 executes the midnight recording display process (S904), and returns to step S903 again.

If the i-th record is not recorded in the middle of the night (NO in S903), the input/output control unit 310 then checks the post-meal flag column of the i-th record to confirm whether the post-meal flag column is logically "false", that is, confirmation. Whether the i-th record is a record in which the blood sugar level before meals is recorded (hereinafter referred to as "pre-meal record"), and the record in which the post-meal flag column is logically "true" is simply referred to as "post-meal record") (S905) ).

When the i-th record is the pre-meal record (YES in S905), the input/output control unit 310 executes the pre-meal record display process (S906), and returns to step S903 again.

If the i-th record is not the pre-meal record (NO in S905), the input/output control unit 310 executes the post-meal record display process (S907), and returns to step S903 again.

FIG. 10 is a flowchart showing the flow of the late night recording display process. FIG. 10 shows the details of step S904 of FIG.

When the processing is started (S1001), the input/output control unit 310 substitutes the counter variable j for the value of the recording index i (S1002).

Next, the input/output control unit 310 decrements the recording index i (S1003), and confirms whether or not the i-th record is a late-night recording (S1004).

In addition, "--" of "i--" described in step S1003 of Fig. 10 means reduction. Similarly, "++" of "i++" described later means increment.

When the i-th record is the late-night recording (Yes in S1004), the input/output control unit 310 returns the process to step S1003, reduces the recording index i by one again, and repeats the determination process of step S1004.

If the i-th record is not recorded in the middle of the night (NO in S1004), the input/output control unit 310 increments the recording index i by one (S1005). Further, the counter variable j is incremented by 1 (S1006), and it is confirmed whether or not the j-th record is a late-night recording (S1007).

When the jth record is the late-night recording (Yes in S1007), the input/output control unit 310 returns the processing to step S1006, and increments the counter variable j by 1, and repeats the determination processing of step S1007.

If the jth record is not the late night recording (NO in S1007), the input/output control unit 310 confirms whether the jth record is measured between 6 am and 10 am, and whether the value of the postprandial flag column is The logical "false" record, that is, whether or not the i-th record is recorded as a blood glucose level when the patient gets up (hereinafter referred to as "morning record") is recorded (S1008).

If the i-th record is the morning record (Yes in S1008), the input/output control unit 310 records the i-th record to the content of the j-th record, that is, two or more records. The blood sugar level and the measurement date and time are displayed on the display unit 309 (S1009).

If the i-th record is not the morning record (NO in S1008), the input/output control unit 310 displays the i-th record to the content of the j-1th record, that is, the blood glucose level of two or more records and the measurement date and time. It is displayed on the display unit 309 (S1010).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S1009 or step S1010, and waits for the operation of the operation button 104 (S1011).

When the up direction button 105 is pressed (Yes in S1012), it is an instruction to trace the measurement history of the blood sugar level. Therefore, the input/output control unit 310 reduces the recording index i by one (S1013), and ends the series of processing (S1014).

When the down direction button 106 is pressed in step S1007 (NO in S1012 to YES in S1015), the input/output control unit 310 substitutes the value of the counter variable j into the recording index i (S1016), and ends one. Series processing (S1014).

When it is determined in step S1007 that the button 107 has been pressed (NO in S1012 to NO in S1015), the input/output control unit 310 ends the history display processing (S1017).

11 and 12 are flowcharts showing the flow of the pre-meal record display processing. Fig. 11 shows the details of step S906 of Fig. 9.

When the process is started (S1101), the input/output control unit 310 substitutes the counter variable j for the value of the recording index i (S1102).

Next, the input/output control unit 310 increments the recording index j by one (S1103), and confirms whether or not the j-th record is a post-meal record (S1104).

If the jth record is post-meal record (Yes in S1104), the input/output control unit 310 displays the contents of the i-th record and the j-th record, that is, the blood glucose levels and the measurement date and time of the two records on the display. The part 309 is on (S1105).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S1105, and waits for the operation of the operation button 104 (S1106).

When the up direction button 105 is pressed (YES in S1107), the input/output control unit 310 reduces the recording index i by one (S1108), and ends the series of processes (S1109).

When the down direction button 106 is pressed in step S1106 (NO in S1107 to YES in S1110), the input/output control unit 310 increments the recording index i by 2 (S1111), and ends the series of processing (S1109). ).

When it is determined in step S1106 that the button 107 has been pressed (NO in S1107 to NO in S1110), the input/output control unit 310 ends the history display processing (S1112).

In step S1104, if the jth record is not the post-meal record (NO in S1104), the input/output control unit 310 displays the content of the i-th record, that is, the blood glucose level and the measurement date and time of one record on the display. The part 309 is on (S1113).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S1113, and waits for the operation of the operation button 104 (S1114). Then, the processing of the input/output control unit 310 proceeds to A of FIG. 12 (step S1215).

The flowchart will be further described with reference to FIG.

When the up direction button 105 is pressed ("Yes" in S1215), input The output control unit 310 reduces the recording index i by one (S1216), and ends the series of processing (S1217).

The flowchart will be further described with reference to Fig. 11 again.

When the down direction button 106 is pressed in step S1114 (NO in S1215 to YES in S1218), the input/output control unit 310 increments the recording index i by 1 (S1219), and ends the series of processing (S1217). ).

When it is determined in step S1114 that the button 107 has been pressed (NO in S1215 to NO in S1218), the input/output control unit 310 ends the history display processing (S1220).

Fig. 13 is a flowchart showing the flow of post-meal record display processing. FIG. 13 shows the details of step S907 of FIG.

When the processing is started (S1301), the input/output control unit 310 substitutes the counter variable j for the value of the recording index i (S1302).

Next, the input/output control unit 310 reduces the recording index i by one (S1303), and confirms whether or not the i-th record is a pre-meal record (S1304).

If the i-th record is a pre-meal record (Yes in S1304), the input/output control unit 310 displays the contents of the i-th record and the j-th record, that is, the blood glucose levels and the measurement date and time of the two records on the display. The part 309 is on (S1305).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S1305, and waits for the operation of the operation button 104 (S1306). Then, the processing of the input/output control unit 310 proceeds to B of FIG. 11 (step S1107).

In step S1304, if the i-th record is not the pre-meal record (NO in S1304), the input/output control unit 310 displays the content of the i-th record, that is, the blood glucose level and the measurement date and time of one record on the display. The part 309 is on (S1307).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S1307, and waits for the operation of the operation button 104 (S1308). Then, the processing of the input/output control unit 310 proceeds to A of FIG. 12 (step S1215).

14(a), 14(b), and 14(c) are diagrams showing an example of display of blood sugar levels on the liquid crystal display 103.

In the case of step S1113, as shown in FIG. 14(a), only the measurement date and time and the blood sugar level are displayed on the liquid crystal display 103.

In the case of step S1105, as shown in FIG. 14(b), the measurement date and time and the blood sugar level are displayed twice on the liquid crystal display 103 for the pre-meal value and the post-prandial value.

In the case of step S1009 and step S1010, as shown in FIG. 14(c), the measurement date and time and the blood sugar level are displayed on the liquid crystal display 103 twice or more as the value at the time of sleeping and the value at the time of getting up.

The operation shown in the flowcharts of Figs. 9 to 13 will be described with reference to Fig. 4 again.

First, the recording index i is initialized to the last record P401 of the blood sugar level table 307 by the input/output control unit 310 in step S902. According to the date and time recorded in the date and time column, the record P401 is not recorded in the middle of the night (No in S903), and the post-meal flag column is logically "false" ("Yes" in S905), so it becomes a pre-meal record display processing. The object of (S906). The record P401 is the last record, and there is no record in which the counter variable j is increased (S1103) (No in S1104), so it becomes a single The displayed object is recorded (S1113).

When the operator presses the up direction button 105 (YES in S1215), the input/output control unit 310 reduces the recording index i by one (S1216), and therefore the recording index i moves to the record P402.

In this way, since the post-meal flag of the record P402 is logically "true" (NO in S903, "NO" in S905), it becomes the object of the post-meal record display processing (S907).

The input/output control unit 310 further reduces the recording index i (S1303), and confirms whether or not the previous record P403 of the record P402 is a pre-meal record (S1304).

According to the date and time of the record P402 which is the i+1th record, the record P403 is within 3 hours, and the post-meal flag is logically "false" ("Yes" in S1304), so that it becomes an object of two record displays. (S1305).

Next, when the operator presses the up direction button 105 (YES in S1215), the recording index i is reduced by one (S1216), and moved to the record P404.

Since the post-meal flag of the record P404 is logically "true" (No in S905), it becomes the object of the post-meal record display processing (S907).

The input/output control unit 310 further reduces the recording index i (S1303), and confirms whether or not the previous record P405 of the record P404 is a pre-meal record (S1304).

According to the date and time of the record P404 which is the i+1th record, the record P405 is within 3 hours, and the post-meal flag is logically "false" ("Yes" in S1304), so that it becomes an object of two record displays. (S1305).

Next, when the operator presses the up direction button 105 (YES in S1215), the recording index i is reduced by one (S1216), and moved to the record P406.

According to the date and time recorded in the date and time column, the record P406 is recorded in the middle of the night (Yes in S903), and therefore becomes the object of the late night recording display process (S904).

The recording index i is temporarily reduced to the record P408 which is not recorded in the middle of the night (S1003 and S1004), and is incremented again (S1005), thereby reaching the record P407. Further, it is confirmed whether or not the j-th record is a late-night recording while increasing the counter variable j (S1006 and S1007). As described above, when the counter variable j points to the record P405 which is the morning record, the determination result of step S1007 becomes "NO". The record P405 is the morning record (Yes in S1008), so the record P407 indicated by the record index i to the counter variable j indicated by the record index i is displayed on one screen (S1009).

Next, when the operator presses the down direction button 106 (YES in S1015), the recording index i is substituted into the value of the counter variable j (S1016), and therefore moves to the record P405. According to the date and time recorded in the date and time column, the record P405 is not recorded in the middle of the night (No in S903), and the post-meal flag column is logically "false" ("Yes" in S905), so it becomes a pre-meal record display processing. The object of (S906). When the value of the recording index i is substituted into the counter variable j (S1102), the counter variable j is incremented (S1103), and it is confirmed whether or not the record P406 indicated by the counter variable j is a post-meal record (S1104).

According to the record P405, the record P406 is a value within 3 hours, and the post-meal flag column is logically "true", so that it becomes an object of two record display (S1105).

As can be seen from the above description, the recording index i is displayed in the middle of the night to the morning (S1009 and S1010), and the case where the pre-meal and post-meal recording (S1105) is displayed, and the input/output control unit 310 is always used as the pointing. The manner in which the first record of the plurality of records of the object is displayed is operated. In contrast, the counter variable j The input/output control unit 310 operates in such a manner as to point to the last record of the plurality of records.

In the case of a meal before and after meals, two records are always displayed. Therefore, the i-th and i+1th records of the post-meal flag "pseudo" are displayed on the display unit 309.

When two or more records are displayed during sleep and when getting up, the i-th record as the data at the time of sleep and the j-th record as the material at the time of getting up are displayed on the display unit 309.

In this way, by displaying two blood glucose levels associated with pre-dinner and post-meal in a single screen, it is possible to determine the change in blood glucose level before and after the diet at a glance. Therefore, the doctor can more accurately ascertain whether the diet taken by the patient is reasonable and whether the insulin taken is reasonable.

Some people with diabetes will have an abnormal rise in blood sugar levels even when they get up in the morning. The reasons for this include "dawn phenomenon" and "Somogyi effect".

The so-called morning dawn phenomenon refers to hyperglycemia caused by the effects of various hormones actively secreted at the morning based on the internal clock, represented by human growth hormone, especially in young patients with type 1 diabetes. Strong tendency. Morning sickness measures can effectively relieve symptoms by taking super-sustained insulin.

The Somoqi effect is also known as the phenomenon of "rebounding of blood sugar levels." If the amount of insulin taken is too high and the patient is in a state of weak hypoglycemia, the liver is reconstituted with a natural recovery effect. Once the liver begins to regenerate sugar, even the newborn sugar When the necessary amount is reached, the liver's sugar regeneration will not stop immediately, so the blood sugar level will increase significantly afterwards. The Somoqi effect measures can suppress symptoms by reducing the amount of insulin taken. Especially in the case of the Somoqi effect in the morning, an effective countermeasure is to reduce the amount of insulin taken before bedtime or to take food supplements.

Although both of the above symptoms are abnormal in the morning when the blood sugar level rises abnormally, the countermeasures are completely different. Therefore, the improvement of symptoms requires an accurate diagnosis.

If you fall into a state of hypoglycemia during sleep, you may wake up late at night due to the action of autonomic nerves. For such patients, the doctor instructs "measure the blood sugar level after waking up in the middle of the night." The blood glucose level during sleep is measured, and the blood glucose level before bedtime and just after getting up is compared, so that the doctor can more accurately understand that the hypoglycemia state when the patient gets up is caused by the morning phenomenon or the Somoqi effect.

[Second Embodiment, Diet Button: Configuration of Blood Sugar Value Table 307]

The blood glucose meter 101 of the present embodiment can be selectively used by switching between the two functional specifications of the blood glucose level before the meal and the blood glucose level after the meal by performing the predetermined setting. Then, another functional specification, that is, a specification of the "diet button" for recording the date and time information of only the start of the diet, is added to the blood glucose level table 307 by the operation of pressing the button immediately before eating.

FIG. 15 is a schematic diagram showing an example of the column configuration and recording of the blood glucose level table 307.

The date and time column and the blood glucose level column are the same as the blood glucose level table 307 of the first embodiment. However, the blood glucose level table 307 of the blood glucose meter 101 of the second embodiment does not have a postprandial flag. Instead, there is a dietary record with a blood glucose value of "zero." Accurate determination The blood glucose level is not zero, so a record with a value of zero in the blood glucose value column is used to indicate the start of the diet. In addition, the method of distinguishing the blood glucose level considers an abnormally high numerical value in which the blood glucose level is impossible to exist, or a setting method such as a negative value. In addition, considering the compatibility of the blood glucose level table 307 with the aforementioned postprandial flag specification, it is also considered to directly use the postprandial flag column as a diet flag.

When starting the diet, the diet record is additionally recorded in the blood glucose level table 307 by long pressing the decision button 107.

In the blood glucose level table 307, a record of recording blood sugar levels and a diet record are recorded in chronological order. Therefore, the final record is the latest record.

[Second Embodiment, Diet Button: Action]

Hereinafter, the flow of the operation of the blood glucose meter 101 of the diet button specification will be described with reference to Figs. 16 to 23 .

FIG. 16 is a flowchart showing the flow of sleep processing of the blood glucose meter 101.

When the processing is started (S1601), the input/output control unit 310 of the blood glucose meter 101 blocks power supply to a device having a large power consumption such as an A/D converter, a display unit 309, or an LED (not shown), and becomes hundreds of A sleep mode in which a low frequency clock of about kHz to several MHz is operated. However, the operation of the operation unit 308 and the micro switch are detected by the input/output control unit 310 (S1602).

The input/output control unit 310 determines whether the operated operation button 104 is a long press of the up direction button 105, that is, whether the power button is pressed or not, and whether the micro switch has a turn-on operation (S1603).

If the power button is pressed, or the micro switch is turned on (S1603 If YES, the input/output control unit 310 executes the main processing (S1604), and thereafter ends the processing (S1605).

If the power button is not pressed and the micro switch is not turned on (NO in S1603), the input/output control unit 310 next determines whether or not the diet button is pressed (whether or not the decision button 107 has a long press) (S1606).

When the diet button is pressed (YES in S1606), the input/output control unit 310 executes a process of additionally recording the diet record in the blood glucose level table 307 (S1607), and thereafter ends the process (S1605).

The sleep process is repeated again after the end of the process, and becomes a loop action.

The flow of the main process of the blood glucose meter 101 of the second embodiment is completely the same as that of the first embodiment shown in FIG. 6, and thus the description thereof is omitted.

FIG. 17 is a flowchart showing a detailed flow of blood sugar level measurement processing in step S606 of FIG. 6.

When the processing is started (S1701), the input/output control unit 310 displays a "wafer mounting instruction" screen on the display unit 309, and instructs the wafer for measuring the blood sugar level to be attached to the optical measurement unit 109 (S1702), and the blood sugar level measuring unit 301 waits for the mounting of the wafer (S1703).

After the wafer is mounted on the optical measurement unit 109, the input/output control unit 310 displays a "blood drip instruction" screen on the display unit 309, instructs the blood to be dropped onto the wafer (S1704), and waits for blood by the blood glucose level measuring unit 301. Dropping (S1705).

When blood is dropped on the wafer, the blood sugar level measuring unit 301 executes the blood sugar level measurement unit. Rational (S1706). The input/output control unit 310 receives the blood glucose level measured by the blood glucose level measuring unit 301, and displays the blood glucose level on the display unit 309 (S1707), and waits for the operation of the operation unit 308 (S1708).

When the decision button 107 is pressed, the input/output control unit 310 additionally records the measured blood glucose level and the date and time for measuring the blood glucose level to the blood glucose level table 307 (S1709), and ends the series of processes (S1710).

Next, the flow of the history display processing of step S608 of Fig. 6 will be described with reference to Figs. 18, 19, 20, 21, 22 and 23. In the history display processing, the input/output control unit 310 uses the recording index i of the natural number. The record index i represents the i-th record of the blood glucose value table 307.

Unlike the first embodiment, the blood glucose level table 307 of the second embodiment does not have a postprandial flag column.

Since the blood sugar level table 307 of the first embodiment has a post-meal flag column, it is possible to instantaneously determine whether the current attention record is a record of the blood sugar level before meals or a blood sugar value after a meal. However, in the case of the second embodiment, there is no post-prandial flag column, and instead, a diet record in which an abnormal value such as a blood sugar level is zero is sandwiched.

Therefore, whether a record is recorded after meals or before meals must be judged based on the date and time when the dietary record is recorded.

In the case of the diet button specification, it is basically recommended to measure the blood sugar level and then press the diet button during the diet. However, depending on the patient's living habits, there are also patients who prefer to measure the blood glucose level after pressing the diet button, and then start the diet. Therefore, the blood sugar level before meals will be determined based on the time when the diet record is recorded, The time of the blood sugar level after meals can be changed to be changeable.

In the present embodiment, the time when the diet record is recorded is defined as "diet time", and the blood glucose value recorded within one hour before and after the "diet time" is treated as the pre-meal value, and one hour after the "diet time" (ie, The blood sugar level recorded within the range of 3 hours after the "pre-prandial value range time" and "drink time" is treated as the post-meal value.

As an example, if the time when the diet record is recorded, that is, the "diet time" is 12:00, the blood glucose level measured from 1100 to 13:00 is treated as the pre-meal value, and it is 13:00 to 15 The blood glucose level measured at time 00 is treated as a postprandial value.

The pre-prandial value range time is preferably set to a range of one hour before and after the "diet time", and the pre-prandial value range time is preferably 30 minutes before and after the "diet time". Further, the time range in which the measured value is treated as the postprandial value is calculated from the time after the end of the pre-prandial value range period, and is at most 3 hours from the "diet time".

FIG. 18 is a flowchart showing the flow of history display processing.

When the processing is started (S1801), first, the input/output control unit 310 sets the recording index i to the last record of the blood glucose level table 307 (S1802).

Then there is the loop processing.

Next, the input/output control unit 310 checks the blood glucose value column of the i-th record of the blood glucose level table 307, and confirms an abnormal value such as a blood sugar level of zero (a value in which the blood sugar level is unlikely to exist, and may be a data other than the numerical value), that is, It is confirmed whether the record is a diet record (S1803). In the case of the food record (Yes in S1803), the input/output control unit 310 executes the record skip process (S1804), and returns to step S1803 again.

If the i-th record is not a diet record (NO in S1803), the input/output control unit 310 then checks the date and time column of the i-th record to check whether the i-th record is measured between 21 and 6 am. Record, that is, confirm whether the i-th record is a late-night record (S1805).

When the i-th record is the late-night recording (Yes in S1805), the input/output control unit 310 executes the midnight recording display process (S1806), and returns to step S1803 again.

If the i-th record is not a late-night recording (NO in S1805), the input/output control unit 310 next looks at one record before and after the i-th record. Further, it is confirmed that the record is a diet record, and it is confirmed whether or not the date and time when the i-th record is recorded is within the time range of the meal prescribed by the time when the meal record is recorded. That is, the input/output control unit 310 confirms whether or not the i-th record is a pre-meal record (S1807).

When the i-th record is the pre-meal record (Yes in S1807), the input/output control unit 310 executes the pre-meal record display process (S1808), and returns to step S1803 again.

If the i-th record is not the pre-meal record (NO in S1807), the input/output control unit 310 then looks at the first two records of the i-th record. Further, it is confirmed that the record is a diet record, and it is confirmed whether or not the date and time when the i-th record is recorded is within the time range of the meal prescribed by the time when the meal record is recorded. That is, the input/output control unit 310 confirms whether or not the i-th record is a post-meal record (S1809).

When the i-th record is post-meal record (YES in S1809), the input/output control unit 310 executes the post-meal record display process (S1810), and returns to the step again. S1803.

If the i-th record is not the post-meal record (NO in S1809), the processing of the input/output control unit 310 proceeds to B of FIG. 22 which will be described later (step S2223).

FIG. 19 is a flowchart showing the flow of the recording skip process. Fig. 19 shows the details of step S1804 of Fig. 18.

When the processing is started (S1901), first, the input/output control unit 310 confirms whether or not the operation button 104 that has just been operated in the history display processing is the up direction button 105 of the retrospective reference blood glucose level table 307 (S1902).

When the operation button 104 that has just been operated is the up direction button 105 (YES in S1902), the input/output control unit 310 next checks whether or not the recording index i is "1", that is, whether or not the recording index i is pointed to the blood sugar level table 307. The first record (S1903).

When the recording index i is "1" (YES in S1903), the input/output control unit 310 increments the recording index i by one (S1904), and ends the series of processing (S1905).

In step S1903, if the recording index i is not "1" (NO in S1903), the input/output control unit 310 reduces the recording index i by one (S1906), and ends the series of processing (S1905).

In step S1902, if the operation button 104 that has just been operated in the history display processing is not the up direction button 105 or is not operated (NO in S1902), the input/output control unit 310 next confirms whether or not the recording index i points to the blood sugar level. The last record of table 307 (S1907).

When the recording index i points to the last record (Yes in S1907), the input/output control unit 310 reduces the recording index i by 1 (S1906), and ends the series of processing. (S1905).

If the recording index i does not point to the last record (NO in S1907), the input/output control unit 310 increments the recording index i by 1 (S1908), and ends the series of processing (S1905).

Fig. 20 is a flowchart showing the flow of the late night recording display processing. FIG. 20 shows the details of step S1806 of FIG. 18.

When the processing is started (S2001), the input/output control unit 310 substitutes the counter variable j for the value of the recording index i (S2002).

Next, the input/output control unit 310 reduces the recording index i by one (S2003), and confirms whether or not the i-th record is a late-night recording (S2004).

When the i-th record is a late-night recording (Yes in S2004), the input/output control unit 310 returns the processing to step S2003, and again reduces the recording index i by one, and repeats the determination processing of step S2004.

If the i-th record is not recorded in the middle of the night (NO in S2004), the input/output control unit 310 increments the recording index i by one (S2005). Moreover, the counter variable j is incremented by 1 (S2006), and it is confirmed whether or not the j-th record is a late-night record (S2007).

If the jth record is a late-night recording (Yes in S2007), the input/output control unit 310 returns the processing to step S2006, and increments the counter variable j by one again, and repeats the determination processing of step S2007.

If the jth record is not the late night recording (NO in S2007), the input/output control unit 310 confirms whether or not the jth record is a diet record (S2008).

If the jth record is a diet record ("Yes" in S2008), input and output control The section 310 increments the counter variable j by 1 (S2009), and proceeds to step S2010.

If the jth record is not a diet record (YES in S2008), the input/output control unit 310 directly proceeds to step S2010.

Next, the input/output control unit 310 confirms whether or not the j-th record is the morning record (S2010).

It is confirmed whether or not the j-th record is a record measured between 6 am and 10 am, and is not included in the post-prande time range specified by the eating record, that is, whether the i-th record is the morning record (S2010).

When the i-th record is the morning record (Yes in S2010), the input/output control unit 310 displays the content of the i-th record to the j-th record, that is, the blood glucose level of two or more records and the measurement date and time on the display. The part 309 is on (S2011).

If the i-th record is not the morning record (NO in S2010), the input/output control unit 310 displays the i-th record to the content of the j-1th record, that is, the blood glucose level of two or more records and the measurement date and time. The display unit 309 (S2012).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S2011 or step 2012, and waits for the operation of the operation button 104 (S2013).

When the up direction button 105 is pressed (YES in S2014), the measurement history of the traced blood glucose level is instructed. Therefore, the input/output control unit 310 reduces the recording index i by one (S2015), and ends the series of processing (S2016).

When the down direction button 106 is pressed in step S2013 (NO in S2014 to YES in S2017), the input/output control unit 310 substitutes the recording index i. The counter changes the value of j (S2018), and ends a series of processing (S2016).

When it is determined in step S2013 that the button 107 has been pressed (NO in S2014 to NO in S2017), the input/output control unit 310 ends the history display processing (S2019).

21 and 22 are flowcharts showing the flow of the pre-meal record display processing. 21 and 22 show the details of step S1808 of Fig. 18.

When the processing is started (S2101), the input/output control unit 310 substitutes the counter variable j for the value of the recording index i (S2102).

Next, the input/output control unit 310 increments the recording index j by one (S2103), and confirms whether or not the j-th record is a post-meal record (S2104).

If the jth record is post-meal record (Yes in S2104), the input/output control unit 310 displays the contents of the i-th record and the j-th record, that is, the blood glucose levels and the measurement date and time of the two records on the display. The part 309 is on (S2105).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S2105, and waits for the operation of the operation button 104 (S2106).

When the up direction button 105 is pressed (YES in S2107), the input/output control unit 310 reduces the recording index i by 2 (S2108), and ends the series of processes (S2109).

When the down direction button 106 is pressed in step S2106 (NO in S2107 to YES in S2110), the input/output control unit 310 increments the recording index i by 2 (S2111), and ends the series of processing (S2109). ).

When it is determined in step S2106 that the button 107 is pressed (No in S2107) In the case of "NO" in S2110, the input/output control unit 310 ends the history display processing (S2112).

In step S2104, if the jth record is not post-meal recording (NO in S2104), the input/output control unit 310 increments the counter variable j by one (S2113), and confirms whether the j-th record is a post-meal record ( S2114).

If the jth record is post-meal record (Yes in S2114), the input/output control unit 310 displays the contents of the i-th record and the j-th record, that is, the blood glucose levels and the measurement date and time of the two records on the display. The part 309 is on (S2115).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S2115, and waits for the operation of the operation button 104 (S2116). Then, the processing of the input/output control unit 310 proceeds to A of FIG. 22 (step S2217).

The flowchart will be further described with reference to Fig. 22 .

When the up direction button 105 is pressed (YES in S2217), the input/output control unit 310 reduces the recording index i by one (S2218), and ends the series of processes (S2219).

When the down direction button 106 is pressed in step S2116 (NO in S2217 to YES in S2220), the input/output control unit 310 increments the recording index i by 3 (S2221), and ends the series of processing (S2219). ).

When it is determined in step S2116 that the button 107 has been pressed (NO in S2217 to NO in S2220), the input/output control unit 310 ends the history display processing (S2222).

In step S2114 of FIG. 21, if the jth record is not a post-meal record (NO in S2114), the process of the input/output control unit 310 proceeds to B of FIG. 22 (step S2223), and the content of the i-th record, that is, the blood glucose level and the measurement date and time of one record are displayed on the display unit 309. (S2223 of Fig. 22).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S2114, and waits for the operation of the operation button 104 (S2224).

When the up direction button 105 is pressed (YES in S2225), the input/output control unit 310 reduces the recording index i by one (S2226), and ends the series of processes (S2227).

When the down direction button 106 is pressed in step S2224 (NO in S2225 to YES in S2228), the input/output control unit 310 increments the recording index i by 1 (S2229), and ends the series of processing (S2227). ).

When it is determined in step S2224 that the button 107 has been pressed (NO in S2225 to NO in S2228), the input/output control unit 310 ends the history display processing (S2230).

Fig. 23 is a flow chart showing the flow of post-meal record display processing. FIG. 23 shows the details of step S1810 of FIG. 18.

When the processing is started (S2301), the input/output control unit 310 substitutes the counter variable j for the value of the recording index i (S2302).

Next, the input/output control unit 310 reduces the recording index i by one (S2303), and confirms whether or not the i-th record is a pre-meal record (S2304).

If the i-th record is a pre-meal record (Yes in S2304), the input/output control unit 310 records the contents of the i-th record and the j-th record, that is, the blood glucose levels of the two records. The measurement date and time is displayed on the display unit 309 (S2305).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S2305, and waits for the operation of the operation button 104 (S2306). Then, the processing of the input/output control unit 310 proceeds to C of FIG. 21 (step S2107).

In step S2304, if the i-th record is not pre-meal recording (NO in S2304), the input/output control unit 310 further reduces the recording index i by one (S2307), and confirms whether the i-th record is a pre-meal record. (S2308).

If the i-th record is a pre-meal record (Yes in S2308), the input/output control unit 310 displays the contents of the i-th record and the j-th record, that is, the blood glucose levels and the measurement date and time of the two records on the display. The part 309 is on (S2309).

The input/output control unit 310 displays the blood glucose level and the measurement date and time on the display unit 309 in step S2309, and waits for the operation of the operation button 104 (S2310). Then, the processing of the input/output control unit 310 proceeds to A of FIG. 22 (step S2217).

In step S2308, if the i-th record is not the pre-meal record (NO in S2308), the process of the input/output control unit 310 proceeds to B in Fig. 22 (step S2223).

The display example of the blood glucose level on the liquid crystal display 103 of the second embodiment is the same as that of the first embodiment shown in FIGS. 14(a), 14(b), and 14(c), and thus the description thereof is omitted.

The operation shown in the flowcharts of Figs. 18 to 23 will be described with reference to Fig. 15 again.

First, the recording index i is initialized to the last record P1501 of the blood glucose level table 307 by the input/output control unit 310 in step S1802. Since the value of the blood glucose level column is "0 mg/dl", the record P1501 is the diet record (YES in S1803), and therefore the object of the record skip process (S1804) is obtained. In the initial stage of the history display processing, the up direction button 105 and the down direction button 106 are not pressed (NO in S1902), so the record index i points to the last record P1501 of the blood sugar level table 307 (Yes in S1907). Therefore, the record index i is reduced by 1 (S1906), and moved to the record P1502. Further, the determination processing of the repeated recording is started again from step S1803.

Since the blood sugar level column records the effective blood sugar level, the record P1502 is not a diet record (No in S1803). Moreover, according to the date and time recorded in the date and time column, the record P1502 is not recorded in the middle of the night ("No" of S1805). Recording records adjacent to P1502 do not exist in the diet bar within the pre-meal time range, so it is not a pre-meal record (No in S1807). The record P1504 before the two records of the P1502 is recorded as the food record, and the time for recording the record P1504 is 30 minutes or more and 3 hours or less. Therefore, the record P1502 is recorded after the meal ("Yes" of S1809), and therefore becomes a meal. The object of the display processing (S1810) is recorded.

When the record index i is reduced by one (S2303) and the record P1503 is viewed, the record P1503 is a pre-meal record within a time range of one hour before and after the diet record P1504 (Yes in S2304), so that the record is displayed on the display unit 309. P1503 and record P1504 these two records (S2305).

Next, when the operator presses the up direction button 105 (YES in S2107), the recording index i is reduced by 2 (S2108), and moved to the record P1505.

The previous record P1506 of the record P1505 is a food record, and P1505 is recorded as a post-meal record based on the date and time ("Yes" in S1809), so that it becomes the object of the post-meal record display process (S1810).

The input/output control unit 310 further reduces the recording index i (S2303), and confirms whether or not the previous record P1506 of the record P1505 is a pre-meal record (S2304). However, since the record P1506 is the diet record (NO in S2304), the input/output control unit 310 further reduces the recording index i (S2307), and confirms whether or not the previous record P1507 of the record P1506 is the pre-meal record (S2308). The record P1507 is recorded in a time range of one hour before and after the date and time when the record P1506 as the eating record is recorded. Therefore, the record P1507 is recorded before meals ("Yes" in S2308), so that it becomes an object of two record display (S2309).

Next, when the operator presses the up direction button 105 (YES in S2217), the recording index i is reduced by 1 (S2218), and moved to the record P1508.

According to the date and time recorded in the date and time column, the record P1508 is recorded in the middle of the night (Yes in S1805), so that it becomes the object of the late night recording display process (S1806).

The recording index i is temporarily reduced to the record P1510 which is not recorded in the middle of the night (S2003 and S2004), and is incremented again (S2005), thereby reaching the record P1509. Further, it is confirmed whether or not the j-th record is a late-night recording while increasing the counter variable j (S2006 and S2007). In this manner, the counter variable j points to the time of the record P1507 recorded as the morning, and the result of the determination in step S2007 becomes "NO". Recording P1507 is not a diet record (No in S2008), but a morning record ("Y" in S2010), so the record P1507 to the counter variable j indicated by the record index i is displayed on one screen. Record P1507 (S2011).

When the operator presses the down direction button 106 (YES in S2017), the value of the counter variable j is substituted into the recording index i (S2018), so the movement is moved to the record P1507. According to the date and time recorded in the date and time column, the record P1507 is not recorded in the middle of the night (No in S903), but is recorded in the time range of one hour before and after the date and time when the record P1506 as the eating record is recorded. Therefore, the record P1507 is recorded before meals (Yes in S1807), and thus becomes the object of the pre-meal record display process (S1808). When the counter variable j is substituted into the value of the recording index i (S2102), the counter variable j is incremented (S2103), and it is confirmed whether or not the record P1506 indicated by the counter variable j is a post-meal record (S2104). However, since the record P1506 is the diet record (NO in S2104), the counter variable j is further increased by 1 (S2113), and it is confirmed whether or not the record P1505 indicated by the counter variable j is a post-meal record (S2114).

Since the record P1505 is a post-meal record recorded for 30 minutes or more and 3 hours or less as the record P1506 of the food record (Yes in S2114), it becomes the object of two record display (S2105).

As can be seen from the above description, when the recording index i is displayed in the middle of the night to the morning (S2011 and S2012) and when the pre-meal and post-meal recording is performed (S2105 and S2115), the input/output control unit 310 is always required. The operation is performed in a manner of pointing to the first record of a plurality of records as display objects. On the other hand, the counter variable j is operated by the input/output control unit 310 so as to point to the last record of the plurality of records.

In the case of a meal before and after meals, for the group recorded before meals and recorded after meals, The process of changing the record index i is distinguished according to where the food record is located.

When the pre-meal recording is recorded after the diet record as in the record P1504, the record P1503, and the record P1502, the process proceeds to step S2105, and the record index i moves across the two records before and after.

When the pre-meal recording is recorded before the diet recording as in the case of the record P1507, the record P1506, and the record P1505, the process proceeds to step S2115, and the record index i moves over one record and then moves over three records.

When two or more records are displayed during sleep and when getting up, the i-th record as the data at the time of sleep and the j-th record as the material at the time of getting up are displayed on the display unit 309.

In this way, by displaying two blood glucose levels associated with pre-dinner and post-meal in a single screen, it is possible to determine the fluctuation of the blood glucose level before and after the diet at a glance. Therefore, the doctor can more accurately ascertain whether the diet taken by the patient is reasonable and whether the insulin taken is reasonable.

[Third Embodiment, Photographing in Blood Glucose Measurement: Configuration of Property Table 313]

The blood glucose meter 101 of the present embodiment includes the imaging element 110 and can be used as a digital camera. Although not performed in the first embodiment and the second embodiment, any condition associated with the blood sugar level can be recorded to the image file by taking a photo immediately after measuring the blood glucose level. In particular, by photographing a diet, it is possible to more accurately estimate the amount of carbohydrate contained in a diet called "carbo count".

FIG. 24 is a schematic diagram showing an example of the column configuration and recording of the attribute table 313. Figure.

The file name of the image file captured by the camera function is stored in the image file name column.

The date and time column stores the date and time when the blood glucose level measured before the image file is to be generated is stored. That is, the same date and time as the content of the date and time column recorded in the blood glucose level table 307 is recorded.

The attribute information attached to the image file, which will be described later in Fig. 28, is stored in the attribute column.

As shown in FIG. 24, there is a blank column record in the date time column and the attribute bar. These records are records that were not originally needed, but are described for ease of understanding.

The blood glucose meter 101 of the present embodiment has a function of taking a photograph associated with the measurement of the blood sugar level in addition to the function of photographing the photograph alone. When a photograph is taken immediately after the blood glucose level is measured, the category of the photograph is selected in FIG. 28 which will be described later. The selected category is recorded as attribute information in the attribute column, and the date and time of the blood glucose level measured immediately before the photograph is taken is recorded in the date and time column. That is, in the content of the date and time column, the blood sugar level table 307 and the attribute table 313 are associated.

[Third Embodiment, Photographing in Blood Glucose Measurement: Action]

Next, the flow of the operation of the blood glucose meter 101 of the specification for performing photographing after the blood glucose level measurement will be described with reference to FIGS. 24 to 29(a) and 29(b). In addition, the third embodiment is a specification of the post-meal button according to the first embodiment.

The flow of the sleep processing of the blood glucose meter 101 is the same as the processing of the first embodiment shown in FIG. 5, and thus the description thereof is omitted.

The flow of the main processing of the blood glucose meter 101 is the same as that of the first embodiment shown in FIG. The processing is the same, and the description is omitted.

FIG. 25 is a flowchart showing a detailed flow of blood sugar level measurement processing in step S606 of FIG. 6.

It is the same as FIG. 7 from FIG. 25 to step S2511. Hereinafter, only differences from FIG. 7 in FIG. 25 will be described.

The input/output control unit 310 additionally records the measured blood glucose level, the date and time of measuring the blood glucose level, and the postprandial flag to the blood glucose level table 307 (S2511), and then checks the internal postprandial flag, and confirms between step S2502 and step S2510. Whether the button after the meal is pressed (S2512).

In the case of the measurement before the meal (Yes in S2512), the input/output control unit 310 executes the photo shooting process (S2513), and ends the series of processes (S2514).

In the case of the measurement after the meal (NO in S2512), the input/output control unit 310 immediately ends the series of processing without executing the photographing processing (S2514).

FIG. 26 is a flowchart showing a detailed flow of the photographing processing of step S2513 of FIG. 25.

When the processing is started (S2601), the input/output control unit 310 displays an imaging guide for the user to select whether or not to take a photo on the display unit 309 (S2602), and waits for the operation of the operation button 104 (S2603).

When the result of the operation of the operation button 104 instructs execution of the shooting (YES in S2604), the input/output control unit 310 displays the attribute selection of the attribute information of the photo selected by the user on the display unit 309 (S2605), and waits The operation of the button 104 is operated (S2606). The user operates the operation button 104 to select an attribute letter. After the interest, perform photo shooting (S2607). The input/output control unit 310 receives the operation of the operation button 104, records the image data as an image file to the mass storage 311, and records the file name of the image file, the date and time of the most recently recorded blood sugar level, and attributes. The information is additionally recorded to the attribute table 313 (S2608), and the series of processing ends (S2609).

In step S2604, if the result of the operation of the operation button 104 instructs not to perform imaging (NO in S2604), the input/output control unit 310 directly ends the series of processing without any operation (S2609).

The flow of the post-meal button detection processing is the same as the processing of the first embodiment shown in FIG. 8, and therefore the description thereof is omitted.

The flow of the history display processing is the same as the processing of the first embodiment shown in FIGS. 9 , 10 , 11 , and 12 , and thus the description thereof is omitted.

FIG. 27 is a flowchart showing a detailed flow of the photo display processing of step S610 of FIG. 6.

When the processing is started (S2701), the input/output control unit 310 initializes the counter variable i to 1 (S2702).

Then it is processed in a loop.

Next, the input/output control unit 310 refers to the attribute table 313 to check whether or not the attribute information is present in the image file for the i-th image file in the image file directory 312 (S2703).

When there is attribute information in the image file ("Yes" in S2703), the image file is an image file that has been taken after the blood glucose level has been measured. Therefore, input and output The control unit 310 next confirms whether or not the attribute information is attribute information indicating a diet (S2704).

If the attribute information is the attribute information of the diet (Yes in S2704), the blood glucose value table 307 associated with the image file is recorded as the blood glucose level before the meal, and the next record of the record may be after the meal. Blood sugar level. Therefore, the input/output control unit 310 next confirms whether or not the next record of the record of the blood glucose level table 307 associated with the image file has a postprandial flag and is measured within 3 hours from the measurement date and time of the previous blood glucose level. Record (S2705).

If the next record of the record of the blood glucose level table 307 associated with the image file has a postprandial flag and is recorded within 3 hours from the measurement date and time of the previous blood glucose level ("Yes" in S2705), then The record and the next record of the blood glucose level table 307 associated with the image file are displayed together with the image file as the blood glucose level before and after the meal (S2706).

Next, the input/output control unit 310 displays the image file, the two blood sugar levels, and the measurement date and time on the display unit 309 in step S2706, and waits for the operation of the operation button 104 (S2707).

When the up direction button 105 is pressed (YES in S2708), the reference to the previous image file is instructed. Therefore, the input/output control unit 310 reduces the counter variable i by one (S2709), and repeats the processing from step S2703 again.

When the down direction button 106 is pressed (NO in S2708 to YES in S2710), the next image file is instructed to be referred to. Therefore, the input/output control section 310 increments the counter variable i by 1 (S2711), and repeats again from step S2703. Reason.

When the decision button 107 is pressed (NO in S2708 to "NO" in S2710), the photo display is ended. Therefore, the input/output control unit 310 ends the series of processing (S2712).

In step S2704, if the attribute information of the image file is not the attribute information of the diet (No in S2704), whether or not the record of the blood glucose level table 307 associated with the image file is substantially irrelevant before meals. Therefore, the input/output control unit 310 next confirms whether or not the next record recorded in the blood glucose level table 307 associated with the image file is a record measured within 3 hours from the measurement date and time of the previous blood glucose level (S2713).

If the next record of the record of the blood glucose level table 307 associated with the image file is a record measured within 3 hours from the measurement date and time of the previous blood glucose level ("Yes" in S2713), the image file will be associated with the image file. The record of the blood glucose level table 307 and the next record are displayed together with the image file (S2714). In addition, step S2706 differs from S2714 in that the former is an action of displaying two blood glucose levels as blood glucose values before and after meals, and the latter is to treat two blood glucose values as blood glucose values before and after meals. And the action shown.

If the next record of the record of the blood glucose level table 307 associated with the image file is not the record measured within 3 hours from the measurement date and time of the previous blood glucose level (No in S2713), only the image will be associated with the image. The record of the blood glucose level table 307 of the file is displayed together with the image file (S2715).

Further, in the same step S2705, the next record of the record of the blood glucose level table 307 associated with the image file is not the date of measurement of the previous blood glucose level. If the record measured within 3 hours or the post-meal flag column of the next record is logically "false" ("No" of S2705), only the record and image of the blood glucose value table 307 associated with the image file will be recorded. The file is displayed together (S2715).

In the case where there is no attribute information in the image file in step S2703 (NO in S2703), the image file is an image file irrelevant to the blood sugar level. Therefore, the input/output control unit 310 displays the image file alone (S2716).

28 is a diagram showing an example of a display screen for attribute selection. FIG. 28 shows an example of step S2605 of FIG. 26.

The photo category is attribute information recorded in the property bar. In Figure 28, there are five types of photos: "Diet", "Sports", "Sleep", "Other", and "Freedom". For example, a value is assigned such that "diet" is 0x01, "sports" is 0x02, "sleep" is 0x03, "other" is 0x04, and "free" is 0x00.

29(a) and 29(b) are diagrams showing an example of a display screen of a photographic image.

Fig. 29 (a) is a diagram showing a state in which a single blood sugar level is displayed together with an image file, which is described in step S2715 of Fig. 27 .

Fig. 29 (b) is a view showing a state in which two blood sugar levels before and after meals are displayed together with an image file, which is described in step S2706 of Fig. 27 .

Photographs of the diet are exemplified in FIGS. 29(a) and 29(b). By showing the content of the diet, doctors can improve the accuracy of dietary carbon.

Thus, by simultaneously displaying the blood sugar level associated with the photographic image, it is expected that the diagnostic accuracy of the doctor is improved.

The blood glucose meter 101 of the present embodiment described above can further be applied as follows.

(1) In the blood glucose meter 101 of the diet button specification, a photograph can be taken in conjunction with the diet button. In this case, the blood glucose meter 101 is brought into a state in which a photograph can be taken by long pressing the diet button, that is, the decision button 107, so that the photograph taken automatically becomes a photograph of the diet.
