DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a blood pressure measuring device, and more particularly to a blood pressure measuring device that provides voice notification of measurement information such as how to wrap an arm cuff.

(b) Conventional technology In general, blood pressure measuring devices use a pressure pump to pressurize the cuff, then slowly exhaust the cuff to reduce the pressure. At the same time, a pressure sensor detects the pressure inside the cuff, and the Korotkoff sound is detected. Some systems detect Korotkoff sounds with a sensor, process the output signals of both sensors with a microcomputer, derive a systolic blood pressure value and a diastolic blood pressure value, and display the values on a display. This type of blood pressure measuring device has an instruction manual that explains how to use it.

(c) Problems to be solved by the invention In general, when measuring blood pressure, care must be taken when handling the arm cuff, etc., and unless certain precautions are taken, inaccurate measurements may be obtained. For example, it may be displayed as normal even though the patient has high blood pressure. Furthermore, errors that make measurement impossible may occur due to surrounding noise, body movements, the constitution of the person taking the measurement, etc. Therefore, it is necessary to wrap the cuff in a predetermined manner, and it is also necessary to take appropriate measures depending on the measurement situation. Therefore, it is essential to check the instruction manual when making measurements. However, because
In conventional blood pressure measuring devices, instruction manuals are only read at the time of purchase, and there is a problem that they can be lost if poorly managed. In addition, it is troublesome for inexperienced measurers to read the instruction manual and become familiar with the operating method.

The signal is output from the speaker 16 via the . The ROM24 contains audio signals for each category indicating how to wrap the cuff, such as "Please pass the cuff over your left arm" and "Please align the microphone with the artery," as well as " Various audio signals such as "ichi", "ni-", "san", etc. are stored in the microcomputer 17.
Measurement information is read out individually by commands from. Therefore, the microcomputer 17, ROM 24, and synthesizer 25 function as a measurement information storage means. Further, the amplifier 26 and the speaker 16 constitute an audio notification means.

Further, in this embodiment device, an explanatory sticker (material) 27 is pasted on the surface of the main body 20, which describes how to wrap the arm cuff, etc. The specific contents of this explanatory sticker 27 are shown in FIG. Explanatory text and explanatory diagrams are provided for each. This explanatory sticker 27 further includes other explanatory text.

Next, the configuration and operation of this blood pressure measuring device 1 will be explained based on the control flow shown in FIGS. 3 and 4.

When the power switch 10 is turned on, the operation starts.
In step ST (hereinafter referred to as ST) 1, initialization processing is performed, and it is determined whether or not there is a shortage of power (battery) (S
T2), this determination is usually NO, and then the process moves to ST3, where the display section 15 displays Step 1 (class number) [see Figure 6 (a)], and how to wrap the arm cuff 1.
0 utterance "Pass the arm cuff over the upper arm of your left arm with your palm facing up" (ST4). This is done by sending the vocal command for how to wrap the arm cuff 1 from the microcomputer 17 to the synthesizer 25, which is an audio IC. The synthesizer 25, which has received this voice command, reads out the corresponding voice signal from the voice ROM 24 and causes the speaker 16 to voice it.

The measurer listens to this voice notification, sees step 1 displayed on the display unit 15, and performs the work as instructed without referring to the diagram of division (step) number 1 on the explanatory sticker 27. .

Next, it is determined whether the step switch 13 has been turned on (Sr1). If the person taking the measurement is still putting the cuff 3 on his arm, he will wait in this step, but if he finishes putting on the cuff and turns on the step switch 13, the judgment of Sr1 will be YES, and the process will move on to Sr1. , step 2 is displayed on the display unit 15 [see FIG. 6(b)], and the arm cuff wrapping method 2 "Please align the mark on the arm cuff with the artery position" is uttered (Sr7). The measurer listens to this voice notification, sees step 2 displayed on the display section 15, and operates as instructed without referring to the diagram of division number 2 on the explanatory sticker 27.

After the operator completes the operation, the operator then presses step switch 1.
When 3 is turned ON, the judgment of Sr8 becomes YES, and step 3 is displayed on the display unit 15 at Sr9 [see Fig. 6 (c)]. "Please turn it down" is uttered (STIO). below,
Further, when the step switch 13 is turned on, 5
The TII determination becomes YES, and the display section 15 displays step 4.
is displayed (ST12) [see FIG. 6(d)], and the arm cuff wrapping method 4, ``Please feel comfortable and relax your arms'' is uttered (ST13).

In the above process, the measurer can read the diagram and explanatory text of the corresponding division number on the explanatory sticker 27 through audio notification and display of the division number.
You can correctly wear the cuff without checking the measurement information.

Furthermore, when the step switch 13 is turned on,
The determination at 5T14 becomes YES, and the process moves to 5TI5.

At this 5T15, the pressure setting value is read and stored. That is, the value set by the pressurization setting value changeover switch 14 is read by the microcomputer 17 and stored. Then, at 5T16, this setting value P, (e.g. 180
mmHg) [see FIG. 6(e)], the synthesizer 25 outputs an audio signal based on the output signal of the microcomputer 17, and the set value is announced audibly from the speaker 16 via the amplifier 26, "180 mm 1 g". (STI7).

Next, at 5T18, it is determined whether the set value P0 has been changed. If the set value uttered at 5T17 is inappropriate, the measurer switches the pressurization set value changeover switch 14, and the determination at 5T18 becomes YES, so 5T16
The screen returns to , and the changed settings are displayed and spoken.

Next, at 5T19, a voice saying "Preparations are complete, please press the start switch" is made.

Then, at 5T20, it is determined whether or not the start switch 13 is turned on, and until it is turned on, the process returns to 5T15, and 5T
The processes from 15 to 5T20 are repeated.

When the measurer judges that the pressurization setting value is appropriate and turns on the start switch 13, the judgment at 5T20 becomes YES, and then the pressurization start is uttered at Sr21, the set value P0 is displayed at 5T22, Thereafter, the quick exhaust valve 6 is closed (5T23), and the pressurizing pump 5 is driven (Sr24).
The inside of the cuff 3 is pressurized. After erasing the display of the pressurization determination value P0 from the display unit 15 (5T25), the current pressure value p in the cuff 3 is read (Sr26), and it is determined whether the set value P0 has been reached ( Sr27). The process returns to 5T26.5T27 until this set value P0 is reached, and then the drive of the pressurizing pump 5 is stopped (Sr28).

Next, the process moves to 5T29, a timer is set for 1 second, and measurement is started (ST30). Then, in 5T31, it is determined whether or not the Korotkoff sound sensor 9 has detected the Korotkoff sound, the CPU 10 waits until the Korotkoff sound is detected, and once it is detected, it is determined whether one second has elapsed (ST32). If the Korotkoff sound is detected after this 1 second has passed, the judgment will be Y due to normal pressurization.
It becomes ES, and the systolic blood pressure value is measured 5T33), the diastolic blood pressure is measured 5T34), and the pulse is measured (Sr35).
. That is, after the microcomputer 17 determines and derives the blood pressure value when the Korotkoff sound occurs and ends, etc., the rapid exhaust valve 6 is opened (5T36) to exhaust the residual pressurized air in the cuff 3.

Subsequently, it is determined whether the measurement results have been derived (S
r17), when measured as described above, the measurement result,
In other words, after displaying the systolic and diastolic blood pressure values on the display unit 15 (Sr38) and audibly announcing them from the speaker 16 (5T39), as shown in FIG. 6(f), the results are compared with the internal data. 5T40), and send the result to speaker 16.
The notification is made by voice (Sr41). That is, it is compared with data stored in the microcomputer 17 in advance, and audible notification is made to tell whether the blood pressure is normal or not, and if it is abnormal, whether it is high blood pressure or low blood pressure.

After that, set the timer for 6 minutes (5T42) and check whether the start switch 13 is turned on (5T43).
), when it is turned ON, the process returns to 5T21, a new measurement is started, and the above-mentioned operation is performed. On the other hand, if it is not turned on, it is determined in 5T44 whether 6 minutes have elapsed, and the system waits for 6 minutes to see if the start switch 13 is turned on, and if it is not turned on, the power is turned off in 5T45.
After the speaker 16 announces that the 5T46
Turn the power supply to 0FFL to prevent power consumption. This ends the measurement operation.

On the other hand, if the Korotkoff sound is detected before 1 second elapses at 5T32, the determination becomes NO because the pressurization is insufficient, and the pressurization set value p is set at 5T47.

It is determined whether or not is greater than 200anlg. When this value is smaller than 200 anl (g, the set value P0 is small, so 30++v+Hg is added (Sr48) and the re-pressurization is notified by voice (Sr49).Then, the process returns to 5T22 and the pressurizing pump 5 is driven again. Then return to the above operation and continue the measurement operation.

Further, when the set value is greater than 200 anlg at 5T47, the process moves to 5T36 and the rapid exhaust valve 6 is opened. Then, since the measurement result was not derived in 5T37, the judgment was No, and after investigating the cause (
Sr50), the cause will be announced by voice from the speaker 16.Sr11), the process will move to 5T42 and the above-mentioned operation will be continued.

Note that if Sr1 determines that there is a power shortage, it will vocalize the power shortage (Sr12) and stop the CPU operation5.
T53), wait 6 minutes with the timer 5T54), and turn off the power (Sr55).

In the above embodiment, the explanatory sticker is attached to the surface of the main body 2, but the main body may be housed in a case with a lid and the explanatory sticker is attached to the back side of the lid.

In addition, in the above embodiment, Sr4, Sr1.5TIO
Although the classification number of 1ST12 is displayed on the display unit 15 that displays the blood pressure value, only the number may be displayed by providing another display. Of course, for the classification display, other than numerical numbers, for example, alphabetic characters or other symbols may be used.

Furthermore, in the embodiment of the first invention, the display of the classification symbol by the display means may be omitted.

Further, in the above embodiment, blood pressure is measured using Korotkoff sounds, but in the present invention, blood pressure may be measured using information detection means that detects pulse waves or the like.

Furthermore, in the above embodiment, it is assumed that the cuff is wrapped around the upper arm to obtain blood pressure measurement data, but the present invention also allows the cuff to be attached to other parts of the body to obtain blood pressure measurement data. Applicable.
