[Prior art]
Since the pulse meter is an indicator of the physiological burden of the body, it is linked to the measurement of the pulse rate during exercise such as walking and jogging outdoors, or the load control part of exercise equipment such as bicycle ergometers and treadmills. It is used for exercise intensity control and physical strength measurement by pulse rate.
[0003]
As a device that prevents the body's physiological burden from becoming excessive during pulse measurement and causing trouble to the body's safety, advice is given when the subject's exercise intensity is not in the proper range. A pulse measuring device has been proposed (see JP-A-7-213499). In addition, a pulse measurement device that notifies by a warning display or a warning buzzer when the pulse rate being measured is not in the normal range from the lower limit pulse rate to the upper limit pulse rate has been commercialized.

Such a conventional pulse measuring device notifies when the pulse rate at the time when the pulse signal is sampled is not a predetermined proper or normal range, but does not take into account the passage of time when the pulse rate changes. Therefore, there was a problem that during the measurement, it was not possible to grasp a physical abnormality caused by a rapid change in the pulse rate, even though the pulse rate was within a predetermined appropriate or normal range. In addition, there was a problem that it was impossible to grasp the physical abnormality that the pulse rate increased during the exercise did not decrease easily after the exercise.
[0005]
Therefore, in order to solve such problems of the conventional pulse measuring device, the object of the present invention is to detect abnormalities in the body by determining abnormalities in pulse change from the amount of change in pulse rate in a predetermined time, and to measure It is to provide a pulse meter with a pulse change determination function capable of improving safety by notifying a person.

[0016]
Next, the operation process of the pulse meter with a pulse change determination function will be described with reference to FIGS.

First, FIG. 3 is a flowchart showing the entire processing procedure. When the power switch 3a of the pulse meter 1 with a pulse change determination function is turned on, all electric devices are initialized in step S1, and the process proceeds to the clock display mode in step S2. In this mode, the current time is displayed on the LCD display 4a. Here, when changing the time, if the B switch 3c is pressed in step S10 without pressing the A switch 3b in step S3, the process proceeds to the time setting mode in step S11. Here, while the hour / minute / second input is switched by the A switch 3b, the numerical value is changed by the C switch 3d to adjust the time. When the B switch 3c is pressed in step S12, the time setting mode ends. Since this process is the same as a known time setting method, detailed description thereof is omitted.
[0017]
When the A switch 3b is pressed in step S3, the process proceeds to the calorie display mode in step S4. In this mode, the calories consumed by measurement are displayed. If the B switch 3c is pressed in step S13 without pressing the A switch 3b in step S5, the process proceeds to various setting modes in step S14. Here, while the input of gender, age, weight, etc. is switched by the A switch 3b, setting of numerical values and selection of conditions are performed by the C switch 3d. When the B switch 3c is pressed in step S15, the various setting modes are ended. In addition, since this process is known as seen in a condition setting method such as a body fat scale, detailed description is omitted.
[0018]
When the A switch 3b is pressed in step S5, the process proceeds to the fat combustion amount display mode in step S6. In this mode, the amount of fat burned by measurement is displayed. When the A switch 3b is further pressed in step S7, the process proceeds to the measurement judgment pulse display mode in step S8. In this mode, the pulse is measured, an abnormality is determined, the pulse rate is displayed on the LCD display 4a, and the exercise intensity is displayed on the bar display 4b. This mode will be described in detail later with reference to FIG. When the A switch 3b is pressed in step S9, the time display mode returns to step S2.
[0019]
Next, the measurement judgment pulse display subroutine shown in FIG. 3 will be described with reference to the flowchart showing the processing procedure of the measurement judgment pulse display mode in FIG.
The measurement of a pulse mainly consists of three measurement steps. One is a step of measuring and displaying a pulse in a resting state before exercise from step S21 to step S23. One is a step of measuring and displaying the pulse during the exercise from step S25 to step S29. One is a step of measuring and displaying the pulse in the recovery state after exercise from step S31 to step S34.

In step S21, the pulse signal is taken in from the photoelectric sensor 5, amplified by the amplifier circuit 8, noise is removed by the low-pass filter circuit 9, converted into a digital pulse signal by the A / D converter circuit 10, and calculated by the arithmetic unit 11. The pulse rate is calculated, and the process proceeds to step S22. When measuring the pulse, the heart rate mark 18 is displayed on the LCD display 4a. In this step S22, the abnormality determination 1 process is performed in a step that will be described in detail later with reference to FIG. In step S23, the pulse rate is displayed on the LCD display 4a. If the C switch 3d is not pressed in step S24, the resting pulse signal before exercise is sampled again, and the processing from step S21 to step S23 is repeated in the same manner.
[0021]
In step S24, the C-switch 3d is pressed at the start of exercise to start measuring the pulse in the exercise state. In step S25, the same process as step S21 is performed, and the process proceeds to step S26. In this step S26, the exercise intensity is calculated by the calculation device 11 using the exercise intensity (%) = (pulse rate at exercise−pulse rate at rest) / (220−age−pulse rate at rest) × 100, and the process proceeds to step S27. .

In step S101, the following warning display is performed. If it is determined in step S40, S45, S61, S66, S80, S86, S90 that there is an abnormality, an exclamation point 17 is displayed on the LCD display 4a as shown in FIG. Is displayed, and the characters “ALERT” and the pulse rate of (a) are alternately switched and displayed. If it is determined in step S60 that it is not appropriate, the bar display 4b displays blinking. As described above, in step S100 and step S101, when the pulse rate is determined to be abnormal, when it is determined that the exercise intensity is not appropriate, or when it is determined that the pulse change is abnormal, abnormality notification is performed. It is a step.
[0044]
In step S102, when the C switch 3d is pressed, the buzzer 16 stops sounding in step S103, the warning display on the display unit 4 ends, and the subroutine is exited.
[0045]
Regarding the abnormality determination in the above description of the present embodiment, all three steps of the pulse measurement in the resting state before the exercise, the pulse measurement in the exercise state, and the pulse measurement in the recovery state after the exercise are performed. However, the process may be performed in one or two steps.
[0046]
Further, the abnormality determination 3 in step S33 in FIG. 4 may be processed as in the flowchart showing the processing procedure of the abnormality determination 4 in FIG. 10 and 7, steps S130 to S139 and steps S80 to S89, steps S142 and S91, and steps S143 and S92 are similar processes. In step S140 of FIG. 10, if the absolute value of the difference between the pulse rate data in the storage unit Z1 of the storage device 12 and the pulse rate data in the storage unit B1 is not less than 12 beats / minute, the pulse change is normal. It is judged, and this subroutine is exited. If it is 12 beats / minute or less, the process proceeds to step S141.
[0047]
In this step S141, when the final exercise intensity during the exercise is 40% or more at the end of the exercise, that is, when the C switch 3d is pressed, the exercise intensity at the end of the exercise is a predetermined value. The pulse amount change amount after a predetermined time has elapsed from the end of the exercise does not change from the predetermined value, and the recovery rate is poor with respect to the pulse rate at rest. Proceeding to S143, abnormality notification processing is performed. If it is less than 40%, the subroutine is exited.
[0048]
In this way, by determining the amount of change in the pulse rate after the lapse of a predetermined time from the end of the exercise, taking the exercise intensity into account, the person to be measured having a low exercise intensity, i.e., the subject whose change in the pulse rate due to the exercise is small Only the person to be measured whose pulse rate does not truly recover can be captured without determining the measurement person as an abnormal pulse change.
[0049]
【The invention's effect】
