Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a biological information measuring system such as an electronic sphygmomanometer, an electronic thermometer, an electronic scale, and a body fat meter is high in the production cost due to large display digits and shows a group of display values which does not relate to the group of display values before or after switching. <P>SOLUTION: The biological information measuring system, which has a memory for storing measured biological information by relating it to time information, includes an arithmetic unit for calculating an arithmetic value from the biological information by a predetermined calculation for every prescribed period based on the time information and a display part for switching the biological information and the arithmetic value and displaying either one of them. If a state displaying the biological information is switched, the calculation value which corresponds to a prescribed period including the displayed biological information is displayed. If a state displaying the arithmetic value is switched, the biological information which is included in a prescribed period corresponding to the displayed arithmetic value is displayed. Consequently, an operator does not have to search a display value again after switching which is related to the display value shown before switching. As a result, the high production cost is prevented because of the few display digits. <P>COPYRIGHT: (C)2005,JPO&NCIPI

In FIG. 1, 11 is a sphygmomanometer, 12 is a sphygmomanometer main body, 7 is a display unit provided on the upper surface of the sphygmomanometer main body 12, and 1 is a wrist cuff attached to the lower surface of the sphygmomanometer main body 12. Reference numeral 6 denotes a switch group including five switches, which are operation means disposed on the upper surface of the sphygmomanometer main body 12, 6a is a power switch, 6b is a select switch used for time correction, 6c is a set switch used for time setting, Reference numeral 6d denotes an average value switch used for calling an average value, and 6e denotes a memory switch used for calling a memory.
[0012]
FIG. 2 is a block diagram showing a functional configuration of the sphygmomanometer shown in FIG. As shown in FIG. 2, the sphygmomanometer includes a cuff 1, which is a zipper for applying pressure to a wrist of a subject and tightening a blood vessel, a pump 3, a pressurizing unit, an exhaust valve 4, a rapid evacuating unit, and a cuff pressure. A pressure sensor 5 as detection means, a tube 2 connecting the pump 3, the exhaust valve 4, and the pressure sensor 5, a switch group 6 as operation means, a microcomputer 8 as control means, and a display section as display means 7 is provided. The pump 3 supplies pressurized air to the cuff 1 to increase the cuff pressure. The exhaust valve 4 is an opening / closing means or the like for removing air from the cuff 1 and rapidly reducing the cuff pressure. The pressure sensor 5 detects the pressure in the cuff 1 and converts it into an electric signal. The microcomputer 8 operates by receiving inputs from the switch group 6 and the pressure sensor 5, and controls the pump 3, the exhaust valve 4, and the display unit 7.
[0013]
The microcomputer 8 includes a CPU and storage means such as a ROM and a RAM (not shown), and is connected to a pulse wave detector 81 which is connected in series from the upper stage to the lower stage, and is branched and connected in the same row below the pulse wave detector 81. A maximum / diastolic blood pressure calculation unit 82 and a pulse rate calculation unit 83 are provided. A memory 85 for storing the biological information of the systolic / diastolic blood pressure calculating section 82 and the pulse rate calculating section 83 in association with the time information from the time measuring section 84; It has an average value calculation unit 86 that calls the numbers and divides the sum of data by the number of data to calculate an average value. The average calculated by the average calculator 86 is stored in the memory 85.
[0014]
FIG. 3 is a schematic diagram for explaining the memory 85. FIG. 3A shows the data of the systolic blood pressure, the diastolic blood and the pulse rate corresponding to the time information stored in the memory No. 90 to memory No. The measured value storage unit 85a stores 90 values up to 1. For example, when the measurement is performed, the memory No. No. 90 stores the measurement time and the measured value as 11:15 AM on March 30, systolic blood pressure 130, diastolic blood pressure 84, and pulse rate 75. 90-No. No. 2 is No. 2. 89-No. No. 1 is stored while being shifted one by one. One data is automatically erased from the memory.
[0015]
FIG. 3B shows a calculated value storage unit 85b that stores the data of the average value for each month for 12 months from the latest month. The sum of the systolic blood pressure, diastolic blood pressure and pulse rate data, the number of data and the average value are stored. For example, 61 measurements have been performed from March 1, 2003 to March 29, 2003. When the 62nd measurement is performed on March 30, 2003, the average value calculation unit 86 calculates The sum, the number of data, and the average value of the systolic blood pressure and the diastolic blood pressure pulse rate up to that of March are called from the value storage unit 85b, 1 is added to each data number, and the current measurement value is added to the sum of each data. Then, the number of data after the calculation and the sum total of the data are overwritten on the previous March data. Then, an average value is calculated as a calculation value from the overwritten data, and the calculated average value is overwritten on the previous March data. For example, for systolic blood pressure, the total sum of data 7874, the average value 127 from the number of data 62, for diastolic blood pressure, the total sum of data 4898, the average value 79 from the number of data 62, and for the pulse rate, the total sum 4278 of the data, the average value 69 from the number of data 62 are 69. Remember.
[0016]
FIG. 4 is an operation flowchart showing the display state. In FIG. 4, S1 indicates a state in which the power is off, S2 indicates a state in which the power SW 6a is turned on (1a), and the pump 3 operates to supply pressurized air to the cuff 1 as shown in S3. To start pressurizing. At that time, the cuff pressure is displayed on the display unit 7. (In the example of S3, 36 mmHg is displayed.) S4 is a state in which a pulse wave is detected. When the pulse wave is detected, the detected pulse wave pressure is displayed. (In the example of S4, 64 mmHg is displayed.) While the cuff 1 is pressurized, the systolic blood pressure value, the diastolic blood pressure value, and the pulse rate are determined based on the detected pulse wave. When the measurement is completed, the systolic blood pressure, the diastolic blood pressure, and the pulse rate are stored together with the time information for each measurement and displayed on the display unit 7. S5 indicates March 31 and S6 indicates 3: 6 pm. Both S5 and S6 are displayed alternately with systolic blood pressure 126, diastolic blood pressure 83 and pulse rate 67. As described above, the measured individual data is written to the memory as the latest data, and the average value is updated.
[0017]
Next, a description will be given of a call operation of each measured value and average value in the measured value group and the average value group, which are two display value groups, and the display at that time. With the memory SW6e, individual biological information stored in the measured value storage unit 85a of the memory 85 can be called together with time information. When the memory SW 6e is pressed ((2a)), as shown in S10, the latest data, for example, memory No. After displaying the 90th data, that is, the 90th data, for one second, the display is automatically switched to the alternate display of S11 and S12. In S11, the systolic blood pressure 130, the diastolic blood pressure 84, and the pulse rate 75 are displayed along with the date (March 30) and in S12, the time (11:15 am). S11 and S12 are displayed alternately, for example, at intervals of 2 seconds. This alternate display or memory No. When the memory SW 6e is pressed again at the time of displaying 90 ((2) b), the next new data, memory No. 89 (S13), that is, the 89th data is displayed. In the example shown in FIG. For example, after expressing 89 for one second, the systolic blood pressure 128, the diastolic blood pressure 78, and the pulse rate 71 are displayed as the measured values at 12:02 pm on March 29. S14 (date and time display) and S15 (time display) are displayed alternately. Hereinafter, similarly, by pressing the memory SW 6e ((2) c), the measured values are sequentially displayed. Although not shown, the oldest measured value No. When the memory SW6e is pressed while the measured value of No. 1 is displayed, the newest measured value No. 1 is displayed. 90 measurements are displayed.
[0018]
On the other hand, the average value of each month stored in the calculated value storage unit 85b of the memory 85 can be called by the average value SW6d. That is, when the average value SW6d is pressed ((3) a), the data of the current month, for example, the average value of March is displayed. As shown in S20, A.S. The highest blood pressure 127, the lowest blood pressure 79, and the pulse rate 69 are displayed as 3 (average value in March). When the average value SW6d is pressed again ((3) b), the average value in February, that is, the systolic blood pressure 131, the diastolic blood pressure 82, and the pulse rate 70 are displayed as shown in S21. Hereinafter, similarly, when the average value SW6d is pressed ((3) c), the average value of the previous month is sequentially displayed. Although not shown, if the average value SW6d is pressed while the average value of the oldest month, April, is displayed, the display returns to the latest average value of March, which is the average value.
[0019]
As a feature of the present invention, for example, as shown in S20, when the memory SW6e is pressed while the average value of March is displayed ((3) e), the memory No. 90, the latest data of March. When the memory SW 6e is pressed while the average value of February shown in S21 is displayed ((3) d), the newest data in February is similarly displayed.
[0020]
Conversely, if the average value SW6e is pressed while displaying the individual measured values ((3) f), the data of the average value of the month corresponding to that day is displayed. For example, the memory No. of S13 When S14 or S15 (measured value on March 29) is displayed with the data 89, the average value for March can be displayed by pressing the average value SW6e.
[0021]
Next, the select SW 6b is used for time adjustment. When the select switch 6b is pressed from the power OFF state of S1 ((4) a), the year correction display of S30 is displayed. The display surface flashes to indicate 2003. In this state, each time the set SW 6b is pressed, a value indicating the year is added by one. When the value of the year to be set is displayed, press the select SW 6b ((4) b). The month correction display of S31 is displayed. In this state, the month is corrected using the set SW6c. Thereafter, the select SW 6b is sequentially pressed ((4) c to (4) e), and the month is corrected in S31, the date is corrected in S32, the hour is corrected in S33, and the minute is corrected in S34 using the set SW 6c. When the power switch 6a is pressed after the measurement is finished except in the power OFF state, the state returns to the power OFF state.
[0022]
As described above, in the present embodiment, the measured 90 pieces of biological information are stored in the memory in association with the time information, and at the same time, the average value information is stored in the memory in association with the 12 months, and displayed. In a state where the biometric information is displayed on the display unit having a small number of digits, a switching operation by pressing the average value SW6d displays an average value corresponding to a predetermined period (one month) including the biometric information. In addition, when the average value is displayed, the memory SW is pressed or the latest individual biometric information for the month is displayed.
[0023]
As described above, according to the present embodiment, when the user of the sphygmomanometer displays the average value and wants to see the individual data within the average period, the display of the individual measurement values is performed by the memory SW6e. When switching to, the displayed value is displayed in order to display the measured value (the latest measured value in February) corresponding to the displayed average value (for example, the average value display in February of S21 in FIG. 4). It is not necessary to recall individual measured values corresponding to the average value of. In addition, it is possible to easily recognize in which period of all the measured values the switched measured value is a measured value.
[0024]
Moreover, when the display is switched from the display of the average value to the display of the measurement value, the latest measurement value within the averaging period is displayed as the corresponding measurement value. You can immediately see the latest information in each period.
[0025]
Also, when switching from the display of individual measurement values to the display of average values, the average value (February average value) corresponding to the measurement value displayed before switching (for example, the February measurement value) is displayed. This eliminates the need to recall the average value corresponding to the displayed measurement value, and allows the user to easily recognize which of the 12 month average values has been displayed.
[0026]
Further, for example, when 90 measured values can be stored in the measured value storage unit 85b of the memory 85, if blood pressure measurement is performed once a day, measured values for three months can be stored. When displaying the measured values of the old date out of the 90 measured values, if the measured values are sequentially displayed one by one only by the memory SW 6e, the memory SW 6e must be depressed dozens of times. It takes time to display.
[0027]
On the other hand, when the measured value corresponding to the displayed average value is displayed as in the embodiment shown in FIG. 4, the average value is sequentially displayed by the average value SW 6d, and the date to be displayed is displayed. When the memory SW6e is pressed when the average value of the month (for example, the average value of January) including the measurement value of (for example, the measurement value of January 10) is displayed, the measurement of the date to be displayed can be performed with a small number of operations. The latest measured value for the same month as the value (for example, January 31) can be displayed. Then, by further pressing the memory SW6e and sequentially displaying the measured values (calling January 10), the measured values of the old date can be easily displayed with a small number of operations.
[0028]
Further, since a switch for switching the display of the average value to the display of the individual measured values within the average period and a switch for sequentially displaying the individual measured values are shared (memory SW6e), the display of the average value is changed to the individual display. After switching to the display of the measured value, the same switch can be used to call the measured value to be displayed during the averaging period, and the operation is simple. Similarly, since a switch for switching from displaying individual measured values to displaying an average value and a switch for sequentially displaying the average value of each month are shared (average value switch SW6d), the display of individual measured values is changed to the average value. After switching to the display of the value, if the switch used for this switching is operated as it is, the average value of each month can be sequentially displayed, and the operability is good. In other words, operability is improved by sharing the switch for switching between the display of the average value and the display of the individual measurement values with the switch for sequentially displaying the individual measurement values and the switch for sequentially displaying the average value of each month. Get better.
[0029]
Although the present embodiment has been described with reference to the electronic sphygmomanometer, the present invention is not limited to the electronic sphygmomanometer, but is applicable to a biological information measuring device such as an electronic thermometer, an electronic weight scale, and a body fat meter. Further, instead of the average value calculation unit 86, a calculation unit for calculating another calculation value may be provided. For example, a standard deviation value for each month may be calculated and displayed. Although the average value is calculated every month, the average value or the standard deviation value may be calculated every week, every 10 days, or every six months.
[0030]
【The invention's effect】
As described above, according to the present invention, it is possible to switch between two display value groups and display one data in the display value group by using a display device having a small number of display digits. Since the displayed value displayed in the display has a predetermined relationship with the display value displayed before the switching, the operator needs to search for the display value related to the display value before the switching again after the switching. Absent. Further, since the number of display digits is small, it is possible to provide an inexpensive biological information measuring device.
