Novel optical pulse-taking instrument system

Abstract

The invention discloses a novel optical pulse-taking instrument system which comprises a voltage-stabilized source, a broadband light source, a drive circuit of the broadband light source, an optical fiber coupler, optical fiber measuring heads, a pneumatic pressure control device, transmission optical fibers, a spectrum demodulator, a data acquisition card, a microprocessor, control signals and a display output unit. Output light signals of the broadband light source are coupled through the optical fiber coupler to the transmission optical fibers; after passing through the measuring heads, the light signals are received through the spectrum demodulator, and received wavelength shift signals are acquired through the data acquisition card and transmitted to the microprocessor; the microprocessor drives a pneumatic control circuit to exert different action forces to the three measuring heads through the output control signals, and the mode of three-finger pulse taking operation in traditional Chinese medicine is simulated; meanwhile, a series of acquired wavelength shift signals are amplified, filtered and separated through the microprocessor, sent to the display output unit and the signals are used for output of pulse wave signals. The novel optical pulse-taking instrument system has the advantages of being simple in structure, high in sensitivity and free of electromagnetic interference, a measuring device is good in sealing performance, and temperature compensation can be achieved.

Description

technical field [0001] The invention relates to a physiological pulse measurement technology, in particular to an intelligent pulse diagnosis detector realized by using fiber grating sensing technology. Background technique [0002] Today, with the rapid development of modern medicine, Western medicine has become the first choice for people to see a doctor. It is mainly due to the characteristics of short course of treatment and quick effect of Western medicine. However, Western medicine also has large side effects, which can easily cause adverse effects such as drug resistance. Traditional Chinese medicine has the advantages of treating both symptoms and root causes, and has few side effects, and is receiving more and more attention. Among them, pulse diagnosis is one of the four diagnostic methods in traditional Chinese medicine (look, smell, ask, feel), that is, pulse diagnosis is an important means of diagnosing diseases. Due to the excessive reliance on old Chinese m...

However, this invention does not take into account the influence of temperature changes on the measurement results. Since the grating is very sensitive to temperature, it will greatly interfere with the measurement of strain.
