Portable program control wireless body sound monitoring system

Abstract

The invention discloses a portable program control wireless body sound monitoring system. The portable program control wireless body sound monitoring system comprises a body sound monitoring instrument and a master control instrument, wherein the body sound monitoring instrument is used for collecting a body sound signal and performing wireless transmission on the collected body sound signal to the master control instrument; the master control instrument is used for receiving and analyzing data information collected from the body sound monitoring instrument, and transmitting a control commandof the master control instrument to the body sound monitoring instrument; the body sound monitoring instrument comprises a body sound collecting module, a power frequency restraining module, a commonmode noise reducing module, a preposition program control differential amplifying module, a program control frequency selecting module, a program control range module, an A / D conversion module, a control module and an RF module; and the master control instrument comprises a processor, an interface unit, a memory unit, a video displaying unit, a data analyzing unit, a stimulation control unit, a video monitoring unit, a system setting unit, a spectrum analyzing and displaying unit, a journal unit and a data recording unit. According to the portable program control wireless body sound monitoringsystem disclosed by the invention, a non-invasive continuous body sound monitoring system is established, a body sound signal of a healthy adult examinee under a normal respiration state is collected.

Description

technical field [0001] The invention relates to the field of body sound monitoring, in particular to a portable program-controlled wireless body sound monitoring system. Background technique [0002] During the physiological activities of some human organs, some sounds will be produced, such as heart sounds of beating heart, breath sounds of gas flow in the respiratory tract, bowel sounds of intestinal peristalsis, etc. These sounds can be collectively referred to as body sounds. They are called physiological body sounds when the organ structure and function are normal, and they are called pathological body sounds when the organ structure and function change. Therefore, by monitoring the changes of these body sounds, the health status of the corresponding organ structure and function of the human body can be understood. Therefore, auscultation becomes an important component of the clinician's physical examination of the patient. [0003] At present, the auscultation instru...

Problems solved by technology

Although it has the advantages of low cost, safety, non-invasive, real-time, etc., it also has the following disadvantages: (1) Subjectivity: the results of auscultation by different doctors may vary greatly, which has a lot to do with the basic skills and experience of doctors; ( 2) Cannot be stored: It is not convenient to understand the progress of the disease and the effect of treatment; (3) Cannot be continuously monitored: Can not provide continuous changes in body sound for critically ill patients; (4) Cannot be implemented remotely: the doctor and the patient must be face-to-face to complete the auscultation This physical examination; (5) Missed diagnosis: Due to the limitation of human hearing, some subtle changes in body voice are easy to miss, which is not conducive to the fine judgment of disease evolution and treatment effect
