  Here, the category morning / night is distinguished by the measured time zone, the category “morning” is 3:00 am to 10:59 am, and the category “night” is 6:00 pm to am Defined as data measured at 2:59. This is a condition category corresponding to a commonly used measurement method for grasping fluctuations in blood pressure data within one day.

  In FIG. 1, reference numeral 110 denotes a main body of the electronic blood pressure monitor 100, 120 denotes an operation unit, 130 denotes a display unit, 140 denotes a cuff, and 150 denotes an air tube. In FIG. 2, reference numeral 210 is a blood pressure measurement unit, 220 is a storage unit, 230 is a CPU that controls the operation of the electronic sphygmomanometer 100, and 240 is a clock unit.

  2, 610 is a measurement / stop button arranged on the operation unit 120, 620 is a user selection button, 630 is a morning / night selection button, 640 is a data advance button, 650 is a data backward button, and 670 is a clock setting button. It is.

  The operation unit 120, the user selection button 620, the morning / night selection button 630, and the data advance button 640 / data backward button 650 are respectively "condition operation unit", "condition data", and "condition selection means". ”And“ memory reading unit ”.

  FIG. 3 illustrates a layout example of each button on the operation unit 120 described above.

  First, an outline of the operation of the electronic blood pressure monitor 100 will be described. Various methods for measuring blood pressure of an electronic sphygmomanometer are known. Here, an oscillometric method is described as an example, but the blood pressure measuring method of the present invention is not limited to this.

When the user presses the measurement / stop button 610 and the CPU 230 receives an instruction to start measurement, the CPU 230 transmits a control signal for starting a blood pressure measurement sequence to the blood pressure measurement unit 210.
When the blood pressure measurement unit 210 receives the control signal, the blood pressure measurement unit 210 inflates by sending air into the cuff 140 through the air pipe 150. The pulse wave component superimposed on the cuff pressure is extracted from the pressure fluctuation of the expanded cuff 140, and the maximum blood pressure and the minimum blood pressure are calculated from the pulse wave amplitude by a predetermined algorithm.

The acquired blood pressure data is displayed on the display unit 130 and is simultaneously stored in the storage unit 220 from the blood pressure measurement unit 210 via the CPU 230. The blood pressure measuring unit 210 is connected to a clock unit 240 as a time measuring unit, and the blood pressure data is stored as a single record together with time data by the clock unit 240, that is, data indicating the date and time. 220.
Further, the acquired blood pressure data is, for example, the user “1” according to the button operation of the operation unit 120.
The “morning” data can be displayed on the display unit 130 under conditions desired by the user.
The present invention focuses on improving the display method of the blood pressure data on the display unit 130.
Next, the blood pressure measurement operation of the electronic sphygmomanometer 100 will be described in detail with reference to FIG. FIG. 4 is a flowchart of blood pressure measurement according to this embodiment.

  In the present embodiment, one electronic sphygmomanometer 100 is configured to be shared by a plurality of users. Although the number of users is not particularly limited, two users (user “1” and user “2”) will be described as an example here.

  When the user presses the measurement / stop button 610 (S410), the electronic sphygmomanometer 100 measures the blood pressure and the pulse (S412) and displays them on the display unit 130 (S414). The user confirms the body movement display (see reference numeral 764 in FIG. 7) and the pulse interval variation display (see reference numeral 762 in FIG. 7) as necessary, and presses the user selection button 620 to store the data. To do. After this depression, the data is stored in the storage area of the user in the storage unit, triggered by the depression of the measurement / stop button (S418).

  By the way, body movement display means that if the user's hand or wrist moves during measurement and a large pressure change is detected, there is uncertainty in the measurement result. This is a notification function. The pulse interval variation display is a display after measurement because the measurement result is uncertain when the interval of the pulse being measured is irregular (so-called irregular pulse beat IHB (Irregular Heart Beat)). This is a function for displaying to the user and informing the user.

  In any case, since the reliability of the measurement result is low, the user preferably performs remeasurement. This function is a function provided for that purpose.

  Here, in the above description, the user presses the user selection button 620 after the blood pressure measurement, but this may be performed immediately before or after the blood pressure measurement measurement / stop button 610 is pressed. In this case, as described above, the storage trigger in the storage unit can be shared by pressing the user selection button 620 again, or a separate storage button may be provided.

Examples of the blood pressure data to be stored and the data associated with the blood pressure data include date, hour and minute “TIM”, systolic blood pressure “SBP” (also referred to as systolic blood pressure, mmHg), systolic blood pressure, and the like. “DBP” (Diastroic Blood Pressure, mmHg, also called diastolic blood pressure) and pulse rate “PLS” (/ min) are set (S418).
Next, the configuration of the storage unit 220 will be described. FIG. 5 is a conceptual diagram showing the configuration of the storage unit according to the present embodiment.
The storage unit 220 is composed of, for example, a RAM. In FIG. 5, ADDRi indicates the address of the RAM, and Rij indicates one record of blood pressure data.
The storage unit 220 is divided into regions according to the number of users. In FIG. 5, reference numeral 310 indicates a storage unit region for the user “1”, and 320 indicates a storage unit region for the user “2”.
Then, in the flowchart of FIG. 4, if the user “1” is selected and blood pressure data storage is instructed for the first time, the blood pressure data is stored in the ADDR1 of FIG. 5 together with the measurement time as a record R11. That is, the content of R11 is
R11 = (TIM1, SBP1, DBP1, PLS1)

  Next, the user selects and presses either the data advance button 640 or the data backward button 650 (S514).

  When the data advance button 640 is selected, the electronic sphygmomanometer 100 reads and displays records that match the “morning” category of the user “1” in order from the newest (S516). That is, in FIG. 5, among R11 to R1n, a record that matches the morning category is selected by TIMi, and sequentially displayed from the newest order.

  Alternatively, as described above, when the storage unit 220 has a morning / night storage unit area, the records in the area are displayed in the newest order.

  Thereafter, each time the data advance button 640 is pressed (S518 to S520), the data is displayed in the newest order (S522), and the process ends.

  If any button other than the data advance button 640 is pressed (S520, or S524 to S526), the process returns to S516, and records are selected again under the re-designated conditions and displayed sequentially.

  When the data backward button 650 is selected, the records that match the “morning” category of the user “1” are read and displayed in order from the oldest, contrary to the above. Thereafter, reading and displaying are performed in the same procedure as when the data advance button 640 is pressed.

  The reading method of the storage unit 220 is cyclically read so that R11 and R1n are connected endlessly, that is, for example, when the data advance button 640 is selected, R1n is read after R11. You may comprise as follows.
