Description
Technical Field
The invention relates to the technical field of intelligent stethoscopes, in particular to a remote intelligent stethoscopes with low cost and high efficiency noise reduction.
Background
Stethoscopes are the most commonly used diagnostic tools for medical personnel, and are often used for listening to heart sounds, breathing sounds, and the like. Through the sound collecting function of the stethoscope, doctors can diagnose whether related viscera have lesions or not according to the characteristics and changes of sound and the own clinical experience.
Based on the current situation of the current internet medical development, telemedicine gradually becomes a trend. For this reason, it is necessary to develop a medical tool that is reliable, easy to popularize and can be used for remote auscultation. Since 1817 the stethoscope was applied to clinic, its external structure and sound transmission mode have been improved, and the stethoscope mainly comprises a sound pick-up part (chest piece), a conduction part (rubber tube) and a sound listening part (ear piece). However, the sound pickup member generates friction noise with the skin of the human body in the process of contacting the auscultation site, and interferes with the diagnosis of the doctor. Remote stethoscopes are more demanding on noise, as their auscultatory sounds are often used for machine-learned sound classification and subsequent analysis.
The patent 'wireless stethoscope' proposes a wireless auscultation method, but the pick-up process of the stethoscope relates to a piezoelectric film sensing diaphragm and a protective diaphragm, so that the noise influence generated when the protective diaphragm is contacted with skin is difficult to avoid, and meanwhile, the stethoscope needs a huge cloud medical system and a remote expert system to support, so that the classification of artificial intelligent auscultation sounds cannot be effectively realized. The patent Internet of things intelligent stethoscope does not relate to noise solutions and artificial intelligent sound classification, and needs cloud platform data management center support. The invention does not relate to artificial intelligence automatic classification of auscultation sounds, and the stethoscope is complex in design, needs various chips to be packaged on a PCB board, and is relatively high in cost and difficult to popularize.
The patent 'noise reduction stethoscope' proposes that a circle of rubber pipeline is arranged outside a vibrating diaphragm, and the noise generated by the movement of a pickup is absorbed by a rubber hose, so that the friction noise generated by the movement is reduced. Although the rubber tube can partially solve auscultation noise during movement, noise sounds generated when the diaphragm of the mechanical stethoscope is possibly in contact with skin are still difficult to avoid, and remote auscultation and artificial intelligence sound classification cannot be realized. The patent 'novel noise reduction intelligent auscultation equipment and system' proposes that the noise during skin contact and movement can be partially eliminated by additionally arranging the noise reduction shockproof ring on the acquisition microphone, but the structural appearance of the auscultation device is enlarged, and meanwhile, the real remote auscultation can not be realized by only using the Bluetooth module, and the artificial intelligent automatic classification function of auscultation sound is not provided.
Although there are many intelligent stethoscopes based on shockproof rubber tubes or rubber tube rings, piezoelectric or capacitive sound sensors for noise reduction, and wireless communication is achieved through a Bluetooth or wifi module, there is no medical tool which has the advantages of efficient noise reduction, extremely low cost, easy popularization and capability of being used for remote auscultation and considering classification of artificial intelligent auscultation sounds, so as to adapt to future deep learning and remote medical market demands of auscultation sounds. Therefore, a new solution is needed.
