Problems solved by technology

However, due to individual differences, when some people are in hypoxic conditions, due to the accumulation of lactic acid under the endocardium, the synthesis of ATP is reduced, resulting in myocardial inhibition, resulting in bradycardia. If the maximum oxygen uptake is calculated based on the current heart rate, the value will be obvious. high

Embodiment Construction

[0015] Overall structural block diagram of the present invention, shown in figure 1 middle.

[0016] figure 1 Here, box 1 is the blood oxygen probe 1, box 2 is the blood oxygen saturation monitoring circuit 2, box 3 is the proportioning component 3, box 4 is the heart rate input component 4, and box 5 is the display component 5.

[0017] The blood oxygen probe 1 is installed on the handle of the maximal oxygen uptake evaluation instrument, corresponding to the finger part. The blood oxygen probe 1 detects the blood flow under the finger skin through an infrared transmitter-receiver. The oxygen content of the blood flow affects the intensity of the infrared light, thereby affecting the intensity of the output signal, which is sent to the blood oxygen saturation monitoring circuit 2 through the output port H1 of the blood oxygen probe 1 . The blood oxygen saturation monitoring circuit 2 converts the signal strength into digital and sends it to the proportioning component circ...

Abstract

The invention relates to a maximal oxygen uptake testing and evaluating apparatus. Maximal oxygen uptake is one of main indexes for evaluating a body strong and healthy degree. According to the existing maximal oxygen uptake testing and evaluating apparatus, bradycardia caused by myocardial dysfunction generated by ATP (adenosine triphosphate) synthesis reduction due to lactic acid accumulation under the endocardium when some people is in a hypoxia state because of individual difference can not be eliminated, and if the maximum oxygen uptake is figured out according to the heart rate at the moment, the numerical value can be remarkably on the high side. In order to reduce errors, an oxyhemoglobin saturation detection device and an oxyhemoglobin saturation and heart rate matching circuit are arranged in the existing maximal oxygen uptake testing and evaluating apparatus. Therefore, the apparatus can be used for achieving the following two effects: the corresponding heart rate when the hypoxia condition occurs can be judged, and the condition of calculating the maximum oxygen uptake according to the low heart rate is avoided; and meanwhile, the degree of utilizing oxygen in a human body by blood can be monitored, and the physique of people to be tested is cooperatively judged.

Description

technical field [0001] The invention relates to an electronic device of a maximum oxygen uptake evaluation instrument, in particular to a device capable of reducing the measurement error of the maximum oxygen uptake and displaying blood oxygen saturation. Background technique [0002] When the existing maximal oxygen uptake measuring instrument is working, the subject is first ordered to exercise at a certain intensity, and then the heart rate after the exercise is measured, and then the maximal oxygen uptake is calculated according to the heart rate. Its advantages are convenient measurement, simple equipment installation and favorable popularization. However, observing the oxygen uptake process of the body during exercise shows that when the amount of exercise is large, the oxygen consumption is intense, and the body appears hypoxic phenomenon. When hypoxia occurs first, the compensatory heart rate acceleration, heartbeat and cardiac output increase. , the circulatory sys...
