Technical field

The invention belongs to the field of stethoscopes, specifically an intelligent stethoscope for internal medicine.

Background technique

Heart sounds and breath sounds are physiological characteristics produced during human heart movement and human respiratory movement. They contain physiological and pathological information about the heart and respiratory system. In the process of developing into electronic stethoscopes, the innovation is only in the hardware aspect. The form is that the electronic microphone receives the sound and then performs filtering, operational amplification, storage, etc. on various electronic hardware to realize the recording of auscultation sound information to generate digital files, storage and Repeat play function. These are all intended to make the heart sound and respiratory sound signals heard more clearly and accurately. However, due to the overlap of the interference noise of the heart sound and respiratory sound with the signal in the spectrum, simply using general hardware functions often cannot effectively eliminate the interference noise. It is necessary to More effective signal processing technology is used to eliminate these interfering noises. Therefore, the current electronic stethoscope cannot truly assist doctors in clinical diagnosis.

Chinese Patent Announcement No. CN102697520B discloses an electronic stethoscope that is used to assist diagnosis by intelligently identifying physiological parameters such as heart sounds and breath sounds, distinguishing types of heart sounds and breath sounds, and extracting disease characteristics. It includes a processor unit and a connected signal acquisition unit, a peripheral drive unit, a storage unit and a data bus interface unit. The signal acquisition unit collects heart sound and respiratory sound signals and performs pre-processing on them. The processor unit specifically implements heart sound processing. and breath sound pattern recognition algorithm and separate the two, complete the intelligent identification and classification of heart sound and breath sound signals, and manage other hardware units; the storage unit is used to store programs and their extensions, and is also used to store heart sounds Breathing sound data, standard heart sounds, breathing sounds, and listening styles of typical cases of diseases can be output and played; the peripheral drive unit and data bus interface unit are used to realize peripheral operation function drive and data communication.

The stethoscope has high accuracy, is easy to operate, is convenient to carry, can quickly diagnose and intelligently identify, and assists doctors in auscultation. However, due to use in clinical settings, stethoscopes may come into contact with multiple patients, posing a risk of cross-contamination. Even with disinfection measures in place, you still need to ensure that all parts of the stethoscope can be thoroughly cleaned and disinfected to prevent the spread of pathogens. And although the processor unit has a pattern recognition algorithm, in some cases there may be issues with signal noise, interference, or changes, which may affect the performance and accuracy of the algorithm. Signal optimization and noise suppression may require additional techniques and algorithms to address complex clinical situations.

The way sound transmission media affects sound quality is complex and diverse. Depending on the amount of water carried by the object, the sound produced when struck will also change. For example, if a glass is filled with different amounts of water, the cup will make different high and low sounds when struck. Different media can affect the speed of sound, frequency response and color of sound. For example, sound traveling in air may be affected by factors such as humidity, temperature, and air pressure, while sound traveling in solids or liquids is affected by properties such as the density and elasticity of the medium. Therefore, this proposal proposes a smart stethoscope for internal medicine.
