Further, although the mechanical measurement method using a pulse rate measuring device can accurately measure the pulse rate, it is inconvenient that the patient must go to a place such as a hospital where the measuring device is installed. Further, even if the detected pulse rate exceeds a predetermined reference value, it is not possible to warn the subject of this fact.

This invention was made in view of the above-mentioned problems.
Convenient to carry and accurately calculates pulse rate.

(Function) In this invention, a pulse rate detection sensor is provided in the device, the number of pulses per unit time is calculated from the pulse rate detected by the pulse rate detection sensor, and the calculation result is displayed on the device. If the pulse rate exceeds the pre-stored reference pulse rate of the subject, an alarm is displayed.

Method (6) is a method in which the sensor is placed at a position slightly in front of the body surface.

On the other hand, the clock signal generation circuit 3 outputs a pulse signal every unit time, and the pulse rate calculation circuit 2 calculates the number of pulses output from the clock signal generation circuit 3 within a certain measurement time and the period between them. The pulse rate per unit time (for example, one minute) is calculated based on the pulse rate output from the pulse rate detection sensor 1.

The alarm display section 8 displays an alarm if the calculated pulse rate exceeds the reference pulse rate as a result of the comparison in the pulse rate comparison circuit 4.

The electrical configuration of this embodiment has been described above. Next, a case where the pulse rate display device having the above configuration is applied to an IC card will be described with reference to FIG. 2.

In this example, the pulse rate detection sensor 1 is a sensor placed at a position slightly away from the body surface to detect a person's pulse rate, and is a sensor of the method (4), (5) or (6) above.

The configuration of this embodiment has been described above. Next, the operation of the pulse rate display device 10 according to this embodiment will be explained with reference to the flowchart of FIG.

First, in step 100, the reference pulse rate α of the person to be measured is input by operating the reference pulse rate manual section 5.

In this case, the reference pulse rate α, as mentioned above, is an index value that serves as a barometer for maintaining the health of the person to be measured, and is manually determined based on the advice of a doctor, etc., for example, to prevent excessive exercise while jogging. The upper limit pulse rate is input.

Next, in step 110, this reference pulse rate α is stored.

Then, in step 120, the pulse rate is detected by the pulse rate detection sensor 1, and in the subsequent step 130,
The pulse rate β of the subject per unit time is calculated while referring to the number of pulses output from the clock signal generation circuit 3.

This is based on the number of output pulses from the clock signal generation circuit 3, and if, for example, 10 pulses are detected in 10 seconds, the single f1° is calculated by assuming the number of pulses per hour β to be 60 times/min. be. Therefore, in this case, the pulse rate calculation circuit 2 can calculate the pulse rate for one minute by simply detecting the pulse rate of the subject for 10 seconds.

In the following step 140, the pulse rate β calculated as described above is displayed on the pulse rate display section 7 on a liquid crystal display.

Then, in the subsequent step 150, the calculated pulse rate β is compared with the reference pulse rate α. Here, if the pulse rate β of the subject is smaller than the reference pulse rate α (YES in step 150)
, the program is terminated, and if β is greater than α (No in step 150), a warning is displayed to the person to be measured (step 160).

In addition, when calculating the pulse rate, the pulse rate for one minute can be calculated by simply detecting the pulse rate for 10 seconds, for example, while referring to the output of the clock signal generation circuit 3, so the pulse rate can be calculated more accurately in a shorter time than in the past. This means that the pulse rate can be measured.

In addition, the reference pulse rate of the person to be measured is stored in the device in advance,
Since a warning is displayed when the pulse rate of the person being measured exceeds the reference value, the reference pulse rate can be set as the upper limit for maintaining the health of the person being measured. If set as an upper limit value to prevent
You will be able to exercise moderately while constantly monitoring your own health condition.

Since the alarm display section 8 is configured in the same manner as in the above embodiment, the same reference numerals are given and detailed explanation thereof will be omitted.
