Electronic stethoscope and electronic stethoscopy system

Abstract

The invention relates to the field of medical instruments, in particular to an electronic stethoscope and an electronic stethoscopy system. The electronic stethoscope comprises an electronic sensor, a microcontroller unit (MCU), a signal selection circuit, a Bluetooth circuit, a display circuit, a storage circuit, a signal processing circuit and a power supply system. The signal selection circuit selects different stethoscopy frequencies through keys, signals are acquired through the electronic sensor, the acquired signals are transmitted to the signal processing circuit, and digital signals obtained after processing are transmitted to the MCU. The Bluetooth circuit, the display circuit, the storage circuit and the power supply system are connected with the MCU, and the Bluetooth circuit is further connected with a plurality of Bluetooth headsets, so that the multi-user stethoscopy function is achieved. The electronic stethoscope is combined with a local PC and a remote PC, has a wide stethoscopy range, a high signal processing capacity and the functions of user-friendly stethoscopy, recording and playback, intelligent stethoscopy, remote consultation and the like, and can be integrated in other medical software systems.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an electronic stethoscope and an electronic stethoscope system. Background technique [0002] Auscultation is a diagnostic method that uses hearing to determine whether a body part is normal based on the sounds emitted by various parts of the body. Whether it is an acoustic stethoscope or a digital stethoscope, its main function is to serve as an auxiliary diagnostic tool for the heart and lungs. Listening to sound signals for diagnosis, the use of acoustic stethoscopes has a history of about 200 years, while electronic digital stethoscopes are a new device developed recently. [0003] At present, the existing electronic digital stethoscopes are mainly divided into three categories: ordinary electronic stethoscopes, electronic stethoscopes with display, and electronic stethoscopes that can be connected to computers through Bluetooth or data lines. These three types of stethoscope...

AI Technical Summary

Problems solved by technology

1. Auscultation range: At present, the auscultation range of the existing electronic stethoscope is relatively narrow. For example, the stethoscope used for auscultation of heart sounds and breath sounds is not suitable for auscultation of fetal sounds or blood vessel sounds. In order to auscultate different content, the traditional electronic stethoscope may need to replace the probe or even It is to replace different stethoscopes, which will lead to a more cumbersome auscultation process and lower efficiency of doctor diagnosis; 2. Multi-person auscultation: the existing electronic stethoscope can generally only support one doctor for auscultation, even if it is a stethoscope that can be connected to a computer. It is also quite inconvenient for many people to auscultate a patient at the same time; 3. Remote consultation: the existing electronic stethoscope does not support remote consultation. Consultation and real-time auscultation of patients can be realized; 4. Data storage and transmission: the existing electronic stethoscope usually does not support the storage and query of SD card, and must be connected to a PC to realize the storage and query function of patient data. If you want to save Or to query data, it must be connected with a specific PC. Therefore, its application range is limited. At the same time, the connection method with the PC is usually to use Bluetooth connection, which has higher requirements for the connected PC, and the connection method cannot be realized. Diversification; 5. Humanization and intelligence: the existing electronic stethoscope needs to contact the probe or electronic sensor with the patient's skin during auscultation, which may cause embarrassment when the patient sees a doctor. At the same time, direct contact with the skin may also lead to the infection of skin diseases. Simultaneously existing stethoscope also can't automatically judge which kind of disease patient may belong to according to sound, intelligence degree is low; System compatibility is poor
