Portable multi-scene application electronic stethoscope

Abstract

A portable multi-scene application electronic stethoscope comprises a stethoscope head, the stethoscope head is connected with a handheld terminal through a connector, and the handheld terminal is connected with an earphone in a wired or Bluetooth mode; according to the stethoscope, an auscultation tube and an ear hook in a traditional stethoscope are omitted and replaced by the Bluetooth earphone and / or the wired earphone, and when the Bluetooth earphone cannot be normally used due to strong electromagnetic radiation interference, the wired earphone is adopted for auscultation; when the wired earphone is inconvenient to use for auscultation, the auscultation sound can be transmitted to the plurality of Bluetooth earphones through the Bluetooth transmitter, so that non-contact auscultation is realized; an audio Bluetooth chip based on Bluetooth 5.0 is used, one-to-many and many-to-many Bluetooth equipment terminals can be connected at the same time, and the Internet-of-Things of the electronic stethoscope is constructed; and compared with Bluetooth 4.0, the transmission speed and the transmission distance are obviously improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a portable multi-scenario electronic stethoscope. Background technique [0002] The stethoscope is a medical diagnostic instrument commonly used by physicians and physicians, and is used for auscultation of patient's breath sounds and heart and lung sounds. A traditional stethoscope usually consists of a sound pickup part (chest piece), a conductive part (rubber tube) and a listening part (earpiece). Due to the shortcomings of traditional stethoscopes such as high noise and weak auscultation sound, people have designed electronic stethoscopes, which use electronic technology to amplify the auscultation sound to overcome the shortcomings of traditional stethoscopes with low sound and high noise. [0003] Through the investigation of existing electronic stethoscopes, it can be found that there are the following deficiencies: most electronic stethoscopes are sti...

AI Technical Summary

Problems solved by technology

Due to the shortcomings of traditional stethoscopes such as large noise and weak auscultation sound, people have designed electronic stethoscopes, which use electronic technology to amplify the auscultation sound to overcome the shortcomings of traditional stethoscopes with low sound and high noise.

[0003] Through the investigation of existing electronic stethoscopes, it can be found that there are the following deficiencies: most electronic stethoscopes are still connected to electronic stethoscopes through earphone cables, and some still retain stethoscope tubes and ear hooks, without the functions of wireless transmission and multi-terminal output

Electronic stethoscopes with tubes or earphone cables cannot be used under the conditions of wearing multiple layers of strict protective isolation clothing in infectious disease areas, limiting their use scenarios

In addition, most electronic stethoscopes currently on the market adopt an integrated structural design, which is not easy to replace parts and is inconvenient to carry
