Visual stethoscope

Abstract

Disclosed herein is a visual stethoscope in which objective diagnosis is possible because a patient and his or her guardian can listen to thoracic and heart sounds also can see the waveform of the data at the time of diagnosis, and reliable diagnosis is possible because clinical data and a medical prescription based on a thoracic and heart sound database and diagnostic software are generated. The visual stethoscope includes a sound collector, a controller and an output unit. The sound collector collects biomedical signals generated from a human body and converts them into electric sound signals. The controller receives and amplifies thoracic and heart sounds output from the sound collector, performs filtering with respect to a predetermined frequency, or performs data conversion and processing, and outputs them. The output unit receives signals output from the controller, and outputs the signals as sound, or diagnoses, analyzes and displays the signals using a predetermined algorithm.

Description

technical field [0001] The invention relates to a visual stethoscope, in particular to a device capable of amplifying and filtering the received chest cavity and heart sounds, and using a biomedical signal analysis algorithm to store or store through a universal serial bus (USB) transmission path terminal. A visual stethoscope that audibly outputs chest and heart sound waveform data. Background technique [0002] The traditional analog stethoscope invented by Laennec in 1819 includes a chest part, an ear part and a conduction tube connecting the chest part and the ear part. [0003] The above-mentioned mechanical stethoscopes have been widely used in various medical fields until now, but recently they have begun to be converted to electronic stethoscopes (using analog amplification technology). [0004] Long-term use of the above-mentioned stethoscope will cause hearing impairment and ear pain of the diagnosing physician, and the occurrence of the ear pain of the physician ...

AI Technical Summary

Problems solved by technology

[0004] Long-term use of the above-mentioned stethoscope will cause hearing impairment and ear pain of the diagnosing physician, and the occurrence of ear pain during diagnosis will cause inconvenience in diagnosis and even misdiagnosis

[0005] In addition, traditional analog stethoscopes and recent electronic stethoscopes can only be heard by doctors when listening to the sounds of the chest cavity and heart. Due to the subjective judgment of doctors, the probability of misdiagnosis is relatively high, and patients and guardians cannot hear sounds through stethoscopes, thereby lead to partial diagnosis

[0006] Also, due to their analog nature, traditional analog stethoscopes cannot store diagnostic data in a database, making remote transmission impossible
