Breath controlled blood circulation flow rate detecting method

Abstract

The breath controlled blood circulation flow rate detecting process includes the following steps: making the testee wear one blood oxygen saturation analyzer and maintain the first breath state; setting one start time for the blood oxygen saturation analyzer to begin recording the blood oxygen saturation values; setting one first time for the testee to change to the second breath state; setting one second time for the testee to change to the third breath state; setting the time corresponding to varying blood oxygen saturation value as the reference signal time based on the recorded values; and obtain the blood circulation flow rate of the testee, which is proportional to the reciprocal of the difference between the reference signal time and the first time.

Description

technical field [0001] The present invention relates to a method for detecting blood circulation flow rate, which is used to obtain the blood circulation flow rate of a test subject, in particular to a method for detecting the blood circulation flow rate of the test subject by controlling the breathing state of the test subject. method. Background technique [0002] In recent years, due to the deteriorating health of people, people have gradually begun to pay attention to issues related to health preservation. For this reason, people are all looking for ways to improve their health status through diet therapy, physical therapy, or drug therapy. However, due to "health" The term does not have an absolute quantitative index, so people often use the quality of blood circulation as a reference index. In other words, when the blood circulation is not good, its "health" should also be bad. And when the blood circulation is good, its "health" should also be good. [0003] However...

Problems solved by technology

[0003] However, how to judge the blood circulation condition that people care about? A known technique is to inject photosensitive substances into the blood of the subject to be tested, and then use photosensitive photography or take pictures to observe the blood circulation of the subject to be tested, but this method can only obtain the blood of the subject to be tested. Circulation status and primary blood flow rate, and it is impossible to repeatedly know the value of blood flow rate in the blood circulation of the subject

[0004] In addition, another known technology is a blood flow rate meter made on the principle of the Doppler effect. The principle is to use an Optical Doppler Tomography (ODT) system for image scanning. The blood flow in the subject's blood vessels can cause the backscattered photons to generate a Doppler frequency shift, and the frequency shift is proportional to the flow velocity, and then the blood flow velocity of the subject can be obtained; but this technology is actually not easy to implement , the reason is that the Doppler frequency shift is accurate for the movement of a specific object, but the flow of blood is continuous, so the measured value is extremely inaccurate and the reproducibility is low. Known technology is not common
