Multiple Physiological Acoustic Parameter Acquisition System

Abstract

The invention discloses a multi-physiological acoustic parameter acquisition system. The acoustic parameter acquisition system comprises at least one acoustic sensor, a signal transmission line and a signal recording device, wherein the acoustic sensor is used for converting human body weak voice or vibration signals into electrical signals; one end of the signal transmission line is connected with each acoustic sensor; the signal recording device is connected with the other end of the signal transmission line, wherein each acoustic sensor is a paster type acoustic sensor or a conformal plug-in acoustic sensor, and at least part of the signal transmission line is embedded into daily necessities. The system can realize the purpose of persistently recording multiple parameters, multiple channels, and multiple scenes for physical physiology signals at the same time.

Description

technical field [0001] The invention belongs to the technical field of medicine, in particular, the invention relates to a multi-physiological parameter acquisition system. Background technique [0002] The human body is a complex physiological system. Many important physiological parameters or processes are detected in the form or carrier of sound signals, such as the heart sound produced by the beating heart, the lung sound produced by the lungs during breathing, the gastrointestinal sound produced by gastrointestinal peristalsis, and The snoring sound caused by the obstruction of the upper airway during sleep is of great significance for monitoring the physiological state of the human body and diagnosing diseases. [0003] Traditionally, mechanical stethoscopes are used to measure most of the physiological acoustic parameters such as heart sounds, lung sounds, and gastrointestinal sounds. Each time, the stethoscope needs to be placed at a specific position to listen to a ...

Problems solved by technology

[0003] Traditionally, mechanical stethoscopes are used to measure most of the physiological acoustic parameters such as heart sounds, lung sounds, and gastrointestinal sounds. Each time, the stethoscope needs to be placed at a specific position to listen to a specific sound, and the signal cannot be continuously recorded. Therefore, the identification and diagnosis mainly rely on Doctors or professionals are based on experience, that is to say, this type of technology is difficult to use for patients' self-detection, such as automatic recording and measurement of relevant signals under sleep

At the same time, from the application point of view, the existing transmission lines cannot adapt to the problems caused by the subjects' continuous turning over in special cases

On the technical level, the electronic stethoscope has solved the problem of signal collection and recording to a certain extent, but it still cannot meet the needs of measuring and recording acoustic parameters anytime and anywhere. etc., but the measured sound intensity is required to be relatively high, and it is difficult to detect the weak sound produced by visceral movement. In addition, the above-mentioned existing methods can only detect single acoustic signals such as snoring, heart sounds, and blood flow noise respectively. It is impossible to obtain these physiological acoustic signals with different amplitudes and frequencies and originating from various parts of the body at the same time, so the diagnostic value is limited
