AI Technical Summary

Technical Problem

Traditional stethoscopes pose safety concerns in infectious disease diagnosis, as they cannot be used properly when healthcare workers are wearing protective gear, and CT scans can damage a patient's immune system. Therefore, a safe and effective diagnostic tool is needed.

Method used

Employing high-definition speakers and resonant damping technology, combined with a traditional stethoscope, it collects sound signals through a microphone, processes them into electrical signals, and then plays them through a high-definition speaker. It is equipped with sound wave graphic display and storage functions, supports wired or wireless transmission, and meets the needs of infectious disease diagnosis.

Benefits of technology

It enables medical staff to clearly hear the patient's heart and lung sounds while wearing protective gear, avoids electromagnetic radiation, supports remote consultations, reduces the number of CT scans, and ensures diagnostic accuracy and safety.

Abstract

An electroacoustic stethoscope provided with a two-channel compatible and acquisition switch relates to the field of medical auscultation, is provided with two channels compatible with auscultation and acquisition, a convenient acquisition switch, a function of analyzing and comparing sound and sound wave graphs and a function of connecting a power amplifier module with two high-definition loudspeakers of a sound box in two output ways, and is a brand-new innovation for diagnosing cardiopulmonary diseases. The excellent electroacoustic quality of the system shows the extremely distinct creative color of the system. Comprising the steps that an electronic auscultation head or a traditional auscultation head collects sound signals, the sound signals are converted into electroacoustic signals through a microphone, auscultation comprises a microphone channel or a microphone wired socket interface which is independently provided with a convenient switch besides heart and lung sound collection, and the convenient switch and the auscultation method thereof are formed. An electroacoustic signal of cardiopulmonary auscultation is collected to suppress howling; the electroacoustic signal enters the function module circuit to be processed through the appropriate transmission mode, and the electroacoustic signal is amplified to drive the loudspeaker to broadcast and stethoscope.
