Electronic stethoscope based on intelligent mobile terminal

Abstract

The invention discloses an electronic stethoscope based on an intelligent mobile terminal. The electronic stethoscope has the advantages that the structure is simple, the size is small, and the priceis low; body surface acoustical signals are electrically conducted after being collected; the body surface acoustical signals can be filtered, amplified, stored, shared, remotely transferred and automatically analyzed. The system comprises an electric wire, a 3.5 mm plug, the intelligent mobile terminal, a microphone and a sound collecting device. The electronic stethoscope can achieve the functions that fetal heart sounds, individual distinctive body surface sound signals and the like are recorded, stored, played back and compared front and back; the body surface sound signals are shared andcan be used for clinical teaching, and it is avoided that each intern needs to repeatedly auscultate the same patient; remote transmission of the body surface sound signals is achieved, a physician can remotely acquire the body surface sound signals of the patient, and the electronic stethoscope can be used for home-based care for the aged and telemedicine; intelligent mobile terminal analyzing software is adopted, the sound signals can be automatically analyzed, and the nuanced difference of the body surface signals can be preliminarily recognized and auscultated by common consumers.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to an electronic stethoscope based on an intelligent mobile terminal. Background technique [0002] The traditional medical stethoscope uses air as a medium to transmit the weak sound from human organs to the human ear through the pipeline. However, this medical stethoscope has the following disadvantages: first, the traditional medical stethoscope has a large volume and is inconvenient to carry; secondly, the signal collected in the auscultation process cannot be adjusted in strength, and external sounds can also pass through the tube wall to generate interference. For some patients with weak signal or hearing-impaired physicians, the identification ability of clinicians is reduced, which brings great troubles to clinical diagnosis. Preservation and objective evaluation of sound signals, sound signals are difficult to share in real time among multiple physicians, and diagnosis also has...

AI Technical Summary

Problems solved by technology

Solve the following shortcomings of traditional stethoscopes: large size and inconvenient to carry; body surface sound signals are transmitted through the air, which is easy to interfere and difficult to record and remote transmission; it is difficult for ordinary users to distinguish subtle differences in body surface sound signals with stethoscopes, and professionalism is required Only personnel can use it; at present, it is difficult for telemedicine to collect the clinically important body surface sound signals obtained by traditional stethoscopes
