Physiological signal detecting system and method

Abstract

The invention provides a physiological signal detecting system and a physiological signal detecting method. The physiological signal detecting system comprises a measuring device, an analog signal processing module, an analog-digital conversion unit and a digital signal processing unit, wherein the measuring device is provided with an optical sensing interface which retrieves optical plethysmogram signals of testees; the analog signal processing module is electrically connected with the optical sensing interface and the analog-digital conversion unit; the optical plethysmogram signals are converted into a digital format by the analog-digital conversion unit; the digital signal processing unit is electrically connected with the analog-digital conversion unit; and the digital signal processing unit senses characteristic points of the optical plethysmogram signals in the digital formats, so that the interphase of the characteristic points and heart rate variability parameters of the testees are calculated. Therefore, users can conveniently sense the heart rate variability parameters per se to achieve the health early warning effect.

Description

technical field [0001] The present invention relates to a physiological signal detection system and its method, especially to an optical physiological signal detection system and its method. Background technique [0002] Since the social structure has changed from a slow-paced agricultural structure to a fast-paced industrial and commercial structure, many people in the country have no time and energy to pay attention to a balanced diet. In addition, the working hours have become longer, so they lack exercise and all kinds of bad With the aggravation of habits, some cardiovascular diseases, such as heart disease and coronary artery disease, which were easy to suffer from in the elderly, continue to decrease every year. Because these diseases have a high probability of sudden death, so pay attention to your heart regularly The health status of blood vessels, and then the adjustment of daily life and eating habits, has become an important topic for Chinese people. [0003] St...

Problems solved by technology

However, every time the electrode patch is used, a special glue must be coated on the electrode patch, so that the electrode patch can be fixed on the body surface of the subject and not easy to fall off, so after each use , the electrode patch must be cleaned, so the electrode patch is easy to wear and must be replaced

On the other hand, for people without a medical background, it is still quite difficult to operate the heart rate variation analysis interface of the computer, so it cannot be popularized and can only be used in clinical research in hospitals
