Quick pulse wave detection system, detection method and detection program

Abstract

The invention discloses a quick pulse wave detection system, a detection method and a detection program. The detection system comprises a photoelectric sensor module, a data processing module, a single-chip microcomputer module, a liquid crystal display module and a power module. The photoelectric detection technology is the basis, a pulse amplitude light modulation technology is adopted to eliminate influences of stray light, dark current and various kinds of interference, and the sampling technology and digital signal processing methods such as digital filtering are adopted to take the place of the function of an amplification and filter circuit in a simulation circuit. Besides, detection time of a pulse value is shortened through design of an algorithm and the purpose of improving work efficiency is achieved. Compared with other pulse measurement devices, the quick pulse wave detection system is high in work efficiency, low in cost, small and convenient to carry, and a patient can collect pulse signals at any time in any place and observe the pulse value. Meanwhile, the pulse value can be accurately measured in 10 seconds, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of human body signal detection in biomedical engineering, in particular to a fast pulse wave detection system, a detection method and a detection program thereof. Background technique [0002] The pulse measuring instrument is an electronic instrument used to measure the pulse rate of the human body, and it has certain importance in modern medicine. Although there are many instruments for measuring pulse at present, they can be used to realize multiple functions such as accurate measurement, accurate display and accurate timing, and there are few portable and fully digital pulse measuring devices. With the improvement of people's living environment and economic conditions, as well as the improvement of cultural quality and the change of lifestyle, the demand for health care, the types of diseases, and treatment measures have undergone obvious changes. At present, cardiovascular and cerebrovascular diseases ...

Problems solved by technology

However, because Chinese medicine relies on fingers to obtain pulse information, although pulse diagnosis is simple, non-invasive, and painless, it is easily accepted by patients, but some defects have also been exposed in long-term medical practice.

First of all, the diagnosis of pulse only depends on the feeling of the doctor's fingers to distinguish the characteristics of the pulse condition, which is limited by feeling, experience and language description, and there are inevitably some subjective factors, which affect the standardization of pulse condition judgment; secondly, this method of using fingers to cut the pulse It is difficult to master the skills; moreover, the perceived pulse condition cannot be recorded and preserved, which affects the research on the mechanism of the pulse condition
