BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blood pressure storage device that stores a plurality of measured blood pressure data and displays the stored blood pressure data.

0002

[Prior art and its problems] Human blood pressure before and after exercise,
It is also known that blood pressure changes significantly before and after taking antihypertensive drugs. It is also known that blood pressure varies depending on the time of day.

[0003] Furthermore, if overnutrition causes poor blood circulation and high blood pressure, it is possible to lower the blood pressure by continuing to perform appropriate exercise. In this case, if you can record changes in blood pressure over a certain period of time and display the memorized data in chronological order, you will be able to see how much your blood pressure has improved due to continued exercise. It will be very convenient.

[0004] Conventionally, however, there are blood pressure recorders that store a plurality of pieces of blood pressure data along with the date and time of measurement. There was no blood pressure recording device that could select and display measured blood pressure data. Furthermore, there was no blood pressure recording device that could display blood pressure data for each measurement condition in chronological order.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the blood pressure memory device of the present invention is applied to an electronic wristwatch.

FIG. 1 is an external front view of an electronic wristwatch with a blood pressure measurement function. In the figure, in the center of the watch case 1 is a liquid crystal display (LCD) 2 that displays time and blood pressure data.
At the bottom of the liquid crystal display section 2 are provided an S4 key that is operated when measuring blood pressure, and an S5 key that is operated when adjusting the time.

A blood pressure measuring section 3 for measuring blood pressure by inserting a finger or the like is provided on the right side of the watch case 1. Also, on the left side is S1, which is operated when switching the operation mode.
key, an S2 key that is operated when reading out stored blood pressure data, and an S3 key that is operated when reading out the next blood pressure data that has the same identification data.

Next, the circuit configuration of the above-mentioned electronic wristwatch is shown in FIG.
Explain with reference to. In the figure, a clock signal with a constant period created by an oscillator 11 is frequency-divided by a frequency division/timing circuit 12 to create a clock signal that serves as a reference for time measurement and a timing signal that controls the operation timing of each part of the circuit. It is output to the control section 13.

The control unit (CPU) 13 is a central processing unit that executes key processing, time measurement processing, blood pressure measurement processing, etc. according to the control program stored in the ROM 14.
R the current time data and measured blood pressure data.
Store in AM15. Further, the control section 13 outputs time data or blood pressure data to the decoder driver 16 and causes the liquid crystal display section 2 to display the data.

FIG. 3 is a diagram showing the configuration of the registers of the RAM 15. The RAM 15 includes a mode register M for storing numerical values corresponding to the operating mode, a register L for storing numerical values corresponding to identification data (described later) of blood pressure data being displayed or being measured, and a register L for storing numerical values corresponding to identification data (described later) of blood pressure data being displayed or being measured. A clock register T for storing the updated current time, and a display register DP for temporarily storing data to be displayed are provided.

[0013] The RAM 15 also stores blood pressure data consisting of a plurality of memory areas consisting of registers DX, DY, DZ, and DS that store the maximum value, minimum value, measurement date and time, and identification data of the measured blood pressure data. A memory D and a pointer P that designates one memory area within the data memory D are provided.

[0014] Here, the identification data is information indicating under what conditions the blood pressure data was measured. In this embodiment, for example, if the blood pressure data was measured after exercise, "No. 1" is If the blood pressure data was measured after medication, "No. 2", if the identification data indicates a specific measurement time period, "No. 3", etc. are stored in the register Ds as identification data.

Returning to FIG. 2, the drive unit 17 and the detection unit 18 constitute the blood pressure measurement unit 3 described above, and the drive unit 17, based on the measurement command signal a from the control unit 13,
Air is supplied to an air chamber (not shown) to compress the measurement part such as a finger at a constant pressure, and the detection unit 18 detects the blood pressure value in the compressed state and in the released state using an optical sensor or the like. This is a circuit that does this. The detection unit 18 measures and detects the systolic blood pressure and diastolic blood pressure, and the detected blood pressure data is output to the control unit 13 together with a measurement end signal.

[0016] Furthermore, the key input unit 19 has the above-mentioned S1
to S5 keys, etc., and outputs operation signals of these keys to the control section 13. The sound alarm section 20 is a circuit that sounds an alarm or the like according to instructions from the control section 13.

Next, the operation of the embodiment configured as above will be explained with reference to the flowcharts of FIGS. 4 and 5. First, the overall processing operation will be explained with reference to the flowchart of FIG. 4(A).

The control unit 13 is normally in the halt state in step S1 in FIG. 4, and if it detects a key operation signal, it executes the key process in step S2, and if it detects a clock signal, it executes the time measurement process in step S3. .

If a clock signal is detected in the halt state, the clock process of step S3 is executed to update the time data in the clock register T of the RAM 15. Next, in step S4, it is determined whether the value of the mode register M is "1" or not,
If M=1, register F is set in the next step S5.
It is determined whether the value of is "1" or not.

When M=1 and F=1, the details will be described later, but it is a blood pressure measurement mode for measuring blood pressure, and in this case, in the next step S6, it is determined whether a measurement end signal is output from the detection unit 18 Determine whether If the measurement end signal is not detected, the process proceeds to step S9, where, for example, a message indicating that measurement is in progress is displayed on the liquid crystal display section 2, and the process returns to step S1.

On the other hand, when the measurement end signal is detected,
The process advances to step S7 and stores the measured maximum and diastolic blood pressure data, which will be described later. However, when the blood pressure data storage process is completed in step S7, the process proceeds to step S8 in FIG. 4(A) and the flag F is
Set "0" to "0" to switch from measurement mode to display mode. As a result, the output of the measurement command signal a is stopped.

Furthermore, in the display processing of the next step S9, the time or blood pressure data is displayed according to the values of the register M and the flag F, as will be described later. On the other hand, if a key operation signal is detected in the halt state in step S1, key processing in step S2 is executed.

The details of this key processing will be explained below with reference to the flowchart shown in FIG. Step S in Figure 5
At step 21, it is determined whether or not the S1 key has been operated. If the S1 key is operated, the next step S22
The value of mode register M is incremented by "1".

That is, the S1 key functions as a display mode switching key, and when the S1 key is operated in the time display mode (M=0) of A in FIG. 6, the data display mode for each identification data of B in FIG. (M=1, F=0). As will be described in detail later, in this mode of displaying data by identification data, the blood pressure data stored in the registers DX and DY of the data memory D can be displayed by the identification data of the register DS.

Further, when the S1 key is operated in the data display mode for each identification data shown in FIG. 6B, the stored data display mode (M=2) shown in FIG. 6D is entered. In this stored data display mode, the data stored in the data memory D can be displayed in the order in which they were stored. Furthermore, if the S1 key is operated in the state shown in D in FIG. 6, M=0 and the time display state returns to A.

If it is determined in step S21 of FIG. 5 that the operated key is not the S1 key, the process advances to step S23 and the S1 key is pressed.
2 Determine whether a key has been operated. If the S2 key is operated, it is determined in the next step S24 whether the value of the mode register M is "1". If M=1, it is further determined in step S25 whether the flag F is "0".

If the S2 key is operated with M=1 and F=0, the value of the register L is incremented by "1" in the next step S26. Since the numerical values such as "1", "2", etc. stored in register L correspond to the aforementioned identification data "No1", "No2", etc., each time register L is incremented, Then, through the display process in step S9 in FIG. 4, the display section 2 displays identification data such as "No. 1", "No. 2", etc. and the latest blood pressure data to which the identification data has been added, as shown in FIG. 6, B. are displayed in order. In addition, Z0 in Fig. 6 is “No1”
The systolic blood pressure data of the blood pressure data to which identification data is attached is "123" and the diastolic blood pressure data is "70".

[0028] Therefore, by operating the S2 key while looking at the displayed identification data, it is possible to select under which conditions the blood pressure data measured will be displayed. For example, immediately after switching from state A to state B (M=1, F=0) in FIG. 6, the latest blood pressure data to which identification data "No1" is assigned is displayed. When the S2 key is operated in this state, the register L is incremented and the blood pressure data to which the next identification data "No. 2" is assigned is displayed. Thereafter, each time the S2 key is operated, the blood pressure data to which the next identification data is assigned is displayed in order.

Returning to FIG. 5, if it is determined in step S23 that the operated key is not the S2 key, the process proceeds to step S27 and it is determined whether or not the S3 key has been operated. If it is the S3 key that has been operated, it is determined in the next step S28 whether the value of the mode register M is "1" or not, and if M=1,
Further, in step S29, it is determined whether the flag F is "0".

If M=1 and F=0, this means that the S3 key is operated in the data display mode for each identification data. In this case, in step S30, the next memory area to which the same identification (classification) data as register L is assigned is specified.

That is, in state B in FIG. 6 (display mode of blood pressure data by identification data), the S3 key is operated to display blood pressure data assigned the same identification data as the value of register L in order. I can do it.

For example, in state B of FIG. 6 (data display mode for each identification data), if the S3 key is operated in state Z0 of FIG. 6 with identification data "No1" selected, the same identification data will be assigned. The blood pressure data with the next newest measurement date and time is displayed as shown in Z1 in the figure, and the next blood pressure data is displayed in order every time the S3 key is operated.

[0033] Therefore, by operating the S2 key, it is possible to select which identification data to display blood pressure data, such as whether to display blood pressure data after exercise or blood pressure data after medication. Further, in this state, by operating the S3 key, blood pressure data of the same identification data as the currently selected identification data can be displayed in order.

[0034] Thereby, blood pressure data measured under specific conditions (eg, blood pressure data after exercise, etc.) can be selected and displayed in order. If it is determined in step S27 of FIG. 5 that the S3 key has not been operated, the process advances to step S31 and it is determined whether the S4 key has been operated. If it is the S4 key that has been operated, measurement start processing in step S32 is executed. In this measurement start process, a measurement command signal a is output to the blood pressure measurement unit 3, and in the next step S33, a flag F indicating the blood pressure measurement mode is set to "1".

That is, when the S4 key is operated, the screen shown in FIG.
Data display mode for each identification data of B (M=1, F=
0) to blood pressure measurement mode of C in Figure 6 (M=1, F=1)
It can be switched to

However, when the blood pressure measurement mode is set to M=1 and F=1 in FIG. 6C, M=1 and F=1 are determined in steps S4 and S5 in FIG. 4A, respectively, as described above. When the end signal is detected in the next step S6, storage processing in step S7 is executed, the details of which are shown in FIG. 4(B).

In this storage process, first, in step S11 of FIG. 4(B), an empty area of the data memory D of the RAM 15 is searched. Then, the identification data corresponding to the value of the register L set in advance by the S2 key at B in FIG. 6 is stored in the register DS of that memory area.

Furthermore, in the next step S13, the highest value of the measured blood pressure data is stored in the register DY, the lowest value in the register DY, and the measurement date and time in the register DZ. Returning to FIG. 5, if it is determined in step S31 that the operated key is not the S4 key, the process advances to step S34 to execute other key processing.

Furthermore, if the value of the mode register M is not "1" in the determination at step S24 in FIG. If M=2, this means that the S2 key is operated in the state D in FIG. 6 (stored data display mode), and in this case, pointer P is incremented in step S36.

That is, the stored data display mode (M=2
), the blood pressure data stored in the data memory D can be displayed in order by operating the S2 key. Next, FIG. 7 is a diagram showing a display state in which blood pressure data to which the same identification data is assigned is displayed in chronological order according to the measurement date and time of the register DZ.

This display is displayed, for example, when a key other than those mentioned above is operated in step S34. That is, for example, when selecting identification data using the S2 key and displaying blood pressure data to which the same identification data as this identification data is assigned, a plurality of blood pressure data with different measurement dates and times are displayed in a graph in chronological order in the order of measurement. I have to.

FIG. 6 is a display example of blood pressure data for identification data "No. 1", in which the highest value (black square) and lowest value (white square) of blood pressure measured this time are displayed at the right end of the graph. The highest and lowest blood pressure values measured last time are displayed on the left side, and the oldest measurement date and time data are displayed in order from the left side of the graph.

Therefore, changes in blood pressure within a certain period of time can be known from the graph shown in FIG. For example, if you are trying to improve your blood pressure by continuing to exercise, you can measure your systolic and diastolic blood pressure after each exercise and use the graph above to see how much your blood pressure has decreased due to exercise. It's easy to know.

In the above embodiment, the measured blood pressure is displayed, but the pulse may be measured and displayed together with the blood pressure. Furthermore, the present invention is applicable not only to electronic wristwatches but also to other electronic devices such as small computers and electronic notebooks.

[0045]

According to the present invention, it is possible to select and display data measured under specific conditions, such as after exercise or after taking medication, from among various types of stored blood pressure data. Furthermore, since the data can be displayed in a time-series graph, changes in blood pressure over a certain period of time can be easily seen.
