Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to an electronic blood pressure monitor, and particularly to an electronic blood pressure monitor that allows a measurer to evaluate measurement results.

(b) Conventional technology In general, electronic blood pressure monitors store result data such as measured systolic blood pressure and diastolic blood pressure in an internal memory or an external memory, and read out the stored data as necessary to read out the data on a weekly or weekly basis. It is displayed continuously on a two-dimensional screen in units of one month, etc., and is used by the person measuring the health condition or by the doctor to make medical decisions by looking at changes in blood pressure values over a predetermined period of time. There is.

(C) Problems to be Solved by the Invention With the above-mentioned conventional electronic blood pressure monitor, changes in blood pressure measured in the past over a predetermined period can be checked at a glance, which is very convenient for the person measuring the blood pressure and the doctor. However, since this type of electronic blood pressure monitor simply plots and displays past measured values on a two-dimensional screen, the average person measuring the blood pressure is wondering whether the situation continues to be favorable or whether it is something that requires caution. In the end, they have to show their measurement data to a doctor and receive advice and guidance. On the other hand, if a doctor comes to consult with past data, it is necessary for doctors to record the appropriate blood pressure range (blood pressure guidance value) in advance in the medical record, etc., for management reasons. , there was a problem that it was complicated.

In view of the above, it is an object of the present invention to provide an electronic sphygmomanometer that allows general individuals to correctly evaluate measurement results and is convenient for professionals such as doctors to handle.

(d) Means and operation for solving the problems The electronic blood pressure monitor of the present invention includes a blood pressure measuring means, a storage medium for sequentially storing the measurement results of the blood pressure measurement, and reading and writing of data in the storage medium. and a display means for displaying past data read from the storage medium on a two-dimensional axis, the storage medium having a storage area for registering blood pressure guidance values. Further, in addition to displaying past data, the display means is characteristically provided with a blood pressure guidance value display section formed by a display line on the blood pressure level corresponding to the value stored in the blood pressure guidance value storage area. It is configured.

In this electronic blood pressure monitor, the result values measured by the blood pressure measuring means are stored as past data, and the blood pressure guidance value storage area of the storage medium stores blood pressure guidance values specific to the person being measured.

When past data is displayed on the two-dimensional display means, blood pressure guidance values are also displayed linearly. Therefore, the person measuring the blood pressure and the doctor check the display of past data and whether the blood pressure has exceeded the guidance value.
Also, everything is within the guidance value, and you can evaluate and judge at a glance whether it is in good condition.

(E) Examples The present invention will be explained in more detail with reference to Examples below.

FIG. 2 is a perspective view of an electronic blood pressure needle showing one embodiment of the present invention.

This electronic sphygmomanometer has a built-in sound sensor 2 for detecting K sound information (see Figure 3), and is connected to a cuff 1 for ischemizing brachial artery blood via a tube 3 to the cuff pressure. It consists of a meter body 4 which is

On the top surface of the instrument body 4, in addition to a display section 5, a power switch 6, a start switch 7, and a pressurization value setting device 8, there are also a memory insertion section 10 for inserting a memory card 9, a write switch 11, and past data. A display designation switch 12 is provided. Further, an earphone 13 for listening to the K sound is connected to the side of the meter body 4 by a jack plug 14.

The display section 5 uses a dot-structured liquid crystal display to enable two-dimensional display.

FIG. 3 is a block diagram showing the circuit configuration of the electronic blood pressure monitor according to the embodiment.

Cuff pressure is determined by pressurizing pump 15, solenoid valve (rapid exhaust valve) 16
, a slow exhaust valve 17, and a pressure sensor 18 to form an air system.

When the start switch 7 is turned on, the pressurizing pump 15 pressurizes the cuff pressure based on the command from the CPU (central processing unit) 20, compressing the brachial artery wrapped around the cuff L, Blood ischemia is achieved by applying pressure above the patient's systolic blood pressure. Thereafter, the air at the cuff pressure is slowly exhausted by the slow exhaust valve 17 at a slow speed of about 2 to 3 mm and 11 g/sec, and the pressure is reduced.

The sound sensor 2 converts the detected sound into an electrical signal, and the amplifier 21 amplifies the sound and outputs it to the CPU 20. Further, the output of the K sound sensor 2 is amplified and derived by an amplifier 23, and when the jack plug 14 is inserted into the jack 24, the sound can be heard through the earphone 13.

The pressure sensor 18 is an electric pressure gauge using a piezoelectric transducer or the like, and constantly detects changes in the pressure applied to the cuff 1, and its detection output (analog amount of cuff pressure) is sent to the A/D converter. 19, the data is converted into a digital value that can be easily taken in by the CPU 20.

The CPU 20 has a built-in memory for storing programs and measurement data, and also has a function of importing cuff pressure data and K sound data, a function of turning on/off the pressurizing pump 15, and a function of calculating blood pressure from sound data in addition to cuff pressure data. It is equipped with a function to determine (blood pressure measurement means), etc.

Furthermore, the determined blood pressure value is output from the CPU 20 and displayed on the display unit 5. Note that 22 is a power supply circuit including a battery.

The memory card (using an IC card, etc.) 9 stores personal data such as name, age, gender, date of birth, height, weight, occupation, and blood type, as well as the date of TD registration and systolic blood pressure. The guidance value and the diastolic blood pressure guidance value are stored. Writing of registration data into these storage areas is performed by a computer (personal computer) at a clinic, hospital, or the like. In particular, the blood pressure guidance value is individually determined and input by the doctor based on past measurement values, diagnostic results, etc. For example, in the case of Mr. A, the systolic blood pressure guidance value (normal range) is 160 to 140 mmHg, and the diastolic blood pressure guidance The value is 90-70 mm/g. The memory card 9 also has a storage area for storing measurement results. Writing of measurement result data to the memory card 9 is performed via the read/write circuit 23, but not all of the measurement results are written, and writing is performed only when the write switch 11 is turned on. be done.

When measuring blood pressure with this electronic sphygmomanometer, when the power switch 6 is on and the start switch 7 is turned on with the Café wrapped around the upper arm, the pressure pump 15 is turned on.
is turned on and the cafe is pressurized to the pressurization set value. Normally, blood flow stops when the pressure is increased to the set pressure. After that, pressurization pump 5 is turned off to stop pressurization, and slow exhaust valve 17 is turned off.
The pressure in the cafe gradually decreases. In other words, it enters the slow exhaust process. In this process, the generation and extinction of a sound are detected by the sound sensor 2, and the output of the corresponding pressure sensor 18 at that time, namely the cuff pressure, is determined to be the systolic blood pressure and the diastolic blood pressure, respectively, and the determined blood pressure value is It is displayed on the display section 5. Blood pressure measurement is performed in the manner described above, and such an operation is already well known.

Further, the measurer listens to the sound through the earphone 13, and only when the sound is normal, turns on the write switch 11 to store the measurement result in the memory card 9. The storage results are stored, for example, once a day, and are sequentially stored in the measurement result storage area along with the month and day data.

In normal measurement, the current measurement result is displayed on the display section 5 as a digital value.

If the measurer wishes to view past data, he or she turns on the past data display designation switch 12. When this past data display designation switch 12 is turned on, the past data display routine shown in FIG. 4 proceeds.

First, initialization such as clearing each display-related register is performed [step ST (hereinafter referred to as ST)l]. Next, the data stored in the memory card 9 is read by the read/write circuit 23 (Sr2).

Next, it is determined whether or not there is measurement data to be displayed (5T3), and if there is no data, the process returns directly. However, if data exists, the month of the latest measurement is stored in register M (the memory of the CPU 20 is used for register M. The same applies to each register below).
Sr4), and stores the numerical value 1 in register D that stores the day (Sr1). Next, it is determined whether there is a measurement result on the day of M month (initially M month 1st), and if there is a measurement result, the systolic blood pressure value of the measurement result is stored in register A, and the diastolic blood pressure value is stored in register B. (Sr7). Then, the display unit 5 displays the position ff indicated by the contents of registers A, B, and D.
f Draw a straight line from (D, A) to (D, B) <
(Sr8), this straight line display is, for example, as shown in a in FIG. Next, it is determined whether D (the contents of register D) has reached 31 (5T9). If D has not reached 31 yet, add 1 to D with 5TIO, that is, the number of days is 1.
increases and returns to Sr1. Thereafter, the processing of S゛T6 to 5TIO is repeated until D≧31, and the vertical lines al, a2, etc. are drawn from the systolic blood pressure value to the diastolic blood pressure value for each day.
... are displayed sequentially.

If the determination of “D≧31” is YES in Sr9, that is, the measurement results a1al from the 1st to the 31st of month M,
..., a! When the display of 1 is completed, it is then determined whether or not there is a blood pressure guidance value (STII).

If the blood pressure guidance value is not stored in the memory card 9, the determination in 5TII is NO and the process returns. In this case, only past data will be displayed on the display section 5.

However, if the blood pressure guidance value is stored in the memory card 9, the determination of 5TII becomes YIF, S, and the upper limit of the systolic blood pressure guidance value (e.g. 160 mmHg) is stored in the register E, and the lower limit of the systolic blood pressure guidance value ( Example: 140 mml1g) are stored in register F, the upper limit of the diastolic blood pressure guidance value (e.g. 90mm1g) is stored in register G, and the lower limit of the diastolic blood pressure guidance value (e.g. 70mmHg) is stored in register H.
(ST12).

Next, draw a straight line e from the coordinates (0, E) to (X 1iaX+ E ) (ST13), and similarly from (0, F) to (
Draw a straight line r to (Xmax, F ) (ST14),
Draw a straight line g from (0°G) to (Xmax, G) (ST
I5), draw a straight line from (0, H) to (Xmax, H) < (ST16). Through the processing from 5T12 to 5T16, the measurement data a, a! are displayed on the display section 5. ,...
..., blood pressure guidance value display lines e, f, g overlaid on affl
, h have been drawn.

The person taking the measurement is OK if the measurement results for each day are between the display line efO for systolic blood pressure and between the display line ghO for diastolic blood pressure; conversely, the more days the measurement results exceed these lines, the more likely the problem is. Yes, it can be determined that caution is required.

In the above embodiment, in the display example shown in FIG. 1, the diastolic blood pressure guidance value display lines e, f and the diastolic blood pressure guidance value display lines g, h
are each simply represented by a single line, but the blood pressure guidance values can be displayed in a wide line by using a different display mode between the display lines ef and between the display lines gh, for example, using different colors. Good too.

Moreover, if the determination result of whether all measurement results are within the blood pressure guidance value is displayed in a blank space on the display section 5, the determination becomes easier.

Further, in the electronic blood pressure monitor of the above embodiment, a memory card is used as a means for storing blood pressure guidance values, etc., but other storage media such as an external memory or a magnetic recording device may be used.

Furthermore, the blood pressure measuring device is not limited to one that employs the K-tone method, but may also employ other well-known principles such as the vibration method.

Furthermore, although the above embodiments have been described in which a two-dimensional display section is provided on the main body of the electronic blood pressure monitor, the present invention may use a CRT display section of a personal computer or the like as the display section.

(f) Effects of the Invention According to this invention, since the measurement results for a predetermined period in the past and the blood pressure guidance values are displayed together on the two-dimensional display means, the person taking the measurement can receive the blood pressure guidance that the doctor has set and registered in advance for the individual. Check whether the measurement result is favorable by referring to the value display line.
You can decide for yourself whether a value requires caution, etc.
Physical condition at the time of measurement and treatment effects can be determined more accurately.

Of course, it also saves doctors the trouble of jotting down each individual's guidance values in their medical records.
