Description

Wrist Pulse Tester

technical field

The utility model relates to an electronic health care product, in particular to a wrist pulse tester.

Background technique

We know that exercise is good for health, but it is difficult to measure the intensity of exercise, especially to help people formulate a reasonable range of exercise intensity, which is even more difficult. Existing pulse testers usually can only test the pulse value of timing, and the exercise intensity must be determined by the judgment of professionals.

Contents of the invention

The utility model provides a wrist-type pulse tester with simple structure, convenient use and early warning of exercise intensity in order to overcome the deficiencies of the above-mentioned prior art.

The purpose of this utility model is achieved by adopting the following technical solutions: a wrist-type pulse tester, comprising a shell and a watch strap, the watch strap is connected to the two ends of the shell, and the upper surface of the shell is provided with a liquid crystal display and a watch strap. The keyboard is provided with a data processing chip and a battery in the casing, and a pulse test sensor is provided on the lower surface of the casing, and the liquid crystal display screen, the keyboard and the pulse test sensor are respectively connected with the data processing chip.

The keyboard is provided with a switch key, a number key, a zero return key, a clear key and a confirmation key.

When this utility model is used, it is worn on the wrist, and the pulse test sensor is touched to the flexor side of the wrist at the pulsation point of the radial artery, and the power is turned on. Then enter the age and resting heart rate, and the instrument can automatically calculate the upper limit and lower limit of the heart rate for the individual during exercise through the program. When exercising, the instrument will automatically compare the calculated upper and lower limits of the heart rate according to the timed heart rate of the athlete. According to different results, different colors will be automatically displayed on the LCD screen to remind the athlete to maintain an appropriate exercise intensity. The utility model has the advantages of simple structure, convenient use, early warning of exercise intensity and the like.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

In Fig. 1, the watch strap 4 is connected to the two ends of the housing 1, the upper surface of the housing 1 is provided with a liquid crystal display 2 and a keyboard 3, the housing 1 is provided with a data processing chip and a battery, and the lower surface of the housing 1 is provided with a There is a pulse test sensor, and the liquid crystal display 2, the keyboard 3 and the pulse test sensor are respectively connected with the data processing chip. The keyboard 3 is provided with an on-off key, a number key, a zero-return key, a clear key and a determination key.

Exercise intensity must be appropriate in order to benefit the body. If the strength is too small, it will not work; otherwise, it will excessively increase the burden on the heart, lungs and other organs, resulting in harmful effects. Exercise intensity was measured as a percentage of maximum exercise capacity ₍ VO ₂ max ), which is the maximum oxygen uptake. Because it is difficult to check VO ₂ max, the pulse rate of different age groups is often used to express this intensity (relative intensity). The ultimate strength is set as 100%, and it is generally required to reach a moderate exercise intensity, that is, to reach 55%-80% of the maximum exercise intensity. That is to say, the goal of exercise is to reach 55%-80% of the maximum heart rate. The specific calculation formula is as follows:

S _up = S _static + (S _max - S _static ) × 80%; S _down = S _static + (S _max - S _static ) × 55%;

Wherein, S _static is counting the number of heartbeats within 1 minute before getting up in the morning; S _max =220-age.

Note that the standard heart rate calculated by this method is not suitable for patients with autonomic neuropathy that affects heart rate or patients taking drugs that affect heart rate.

Input the above formula into the chip processing program of the test instrument, the doctor or the person only needs to input the age and resting heart rate, and the instrument can automatically calculate the upper limit and lower limit of the individual's heart rate during exercise. When exercising, it is worn on the wrist through the watch strap 4, and the pulse test sensor is touched to the pulse of the flexor radial artery of the wrist, the power is turned on, and the instrument starts to work. It can measure the real-time heart rate of the athlete and compare it with the calculated upper limit and lower limit of the heart rate. If the timing heart rate is below the lower limit, it means that the exercise intensity is too low, and it is necessary to increase the exercise intensity. At this time, the display screen 2 of the instrument will appear yellow; if the timing heart rate is between the upper and lower limit values, it means that the exercise intensity is appropriate and should be maintained. The display screen 2 of the instrument shows green; if the timing heart rate is above the upper limit, it means that the amount of exercise is too large, and the exercise intensity needs to be reduced, and the display screen 2 of the instrument displays red at this time. Athletes only need to pay attention to the color displayed on the instrument worn on the wrist when exercising, and adjust their exercise intensity according to the color change, so as to maintain an appropriate exercise intensity and strong operability. It will play a positive role in exercise therapy for diabetics and obese patients, and for healthy adults to use exercise to strengthen their bodies.
