Multifunctional stethoscope for broadband parameter monitoring and implementation method of multifunctional stethoscope

Abstract

The invention discloses a multifunctional stethoscope for broadband parameter monitoring and an implementation method of the multifunctional stethoscope. The multifunctional stethoscope comprises an auscultation head, an electret capacitor, a heart sound sensor based on the auscultation head and the electret capacitor, a rubber tube and a Y-shaped sound dividing tube. A thin film of the auscultation head and the electret capacitor form the heart sound sensor, a lead of the heart sound sensor is connected to a circuit board in the rear portion of the auscultation head, and an audio plug, an LED display screen and an LCD screen located at a connector of the Y-shaped sound dividing tube are connected to the circuit board. Through the multifunctional stethoscope, users can quickly adjust positions to find proper auscultation points through feedback waveform information; received sound signals are sent to third parties, namely the users through the audio plug on the circuit board, multiple people can conduct monitoring, and site consultation is promoted; display is conducted through the LED display screen, and therefore patients or medical workers can read out measured signal data more visually; measuring display can be conducted at different positions by connecting the connector to the external LCD screen, and the multifunctional stethoscope is suitable for site consultation among multiple people.

Description

technical field [0001] The invention relates to a medical device, in particular to a multifunctional stethoscope for wideband parameter monitoring and a realization method thereof. Background technique [0002] The frequency distribution of the heart sound signal is from 20HZ-600HZ, often accompanied by strong interference. The sensor is an important part of heart sound digitization processing, and its quality directly affects the processing result. In order to obtain the heart sound signal without distortion as much as possible, the sensor is required to have the characteristics of high sensitivity, ultra-light weight, high precision, high stability, wide frequency response, flat response, and large dynamic range. [0003] The stethoscope is the most commonly used diagnostic tool for internal and external gynecologists and children, and is a symbol of doctors. Modern medicine began with the invention of the stethoscope. Since the stethoscope has been used in clinical prac...

Problems solved by technology

[0007] The purpose of the present invention is to provide a multifunctional stethoscope for wideband parameter monitoring, which solves the problems that current stethoscopes have poor response to weak signals, cannot hear sounds, cannot display waveforms synchronously, and cannot listen to multi-band physiological signals at the same time. It is difficult for personnel to use, improves the ability of novices to use, and facilitates medical staff to accurately grasp the patient's chest voice
