Description

An electronic stethoscope system

【Technical field】

The invention relates to the technical field of medical equipment, in particular to an electronic stethoscope system.

【Background technique】

Stethoscope is a commonly used diagnostic tool for doctors. The traditional acoustic stethoscope has simple structure, poor anti-interference ability, and inaccurate diagnosis. With the advancement of electronic technology, electronic stethoscopes are gradually being widely used because of their accurate diagnosis and strong ability to resist noise interference. But in the circuit of existing electronic stethoscope, generally all need to be provided with amplifier, this amplifier can transmit in the earplug after the sound that stethoscope head detects is amplified, and then guarantees that doctor can hear moderate and clear physiological sound (heart sound, lung sound) , visceral sounds, etc.). But in the actual process, it is inevitable that the auscultation head will fall or collide with other objects. The collision sound of the auscultation head will be amplified by the amplifier and will make a louder sound from the earplugs. If the earplugs are still plugged into the doctor's ears Guo Nei will cause great damage to the doctor's hearing, and even cause temporary tinnitus or eardrum damage to the doctor, and after long-term use, it will cause the doctor's hearing loss and affect the diagnosis.

Electronic digital stethoscope is the novel equipment that develops recently. As portable diagnosis and treatment equipment, most electronic digital stethoscopes have relatively simple functions. The diagnosis process still needs to rely on years of clinical experience of medical staff to make a clear judgment. However, it also greatly consumes the experience and time of medical staff, resulting in low diagnosis and treatment efficiency and further straining medical resources. .
