Abstract

The invention discloses a wireless transmission stethoscope. The stethoscope senses the pressure of a main stethoscope head body and the skin of a patient through a pressure sensor and indirectly judges whether or not voice heard by a doctor is high-frequency voice or low-frequency voice, by comparing the magnitude of output levels of a circuit, an amplification circuit is controlled to adjust thefrequency response of the amplification circuit, it is guaranteed that the amplification circuit only amplifies a signal of a certain frequency segment, other signals are filtered away, voice collection is best, and finally signal transmission between a stethoscope head and a double-lug hanging tube is achieved through a first wireless receiving and transmission circuit and a second wireless receiving and transmission circuit.

Description

technical field [0001] The invention relates to the technical field of stethoscope structures. Background technique [0002] The traditional double-headed stethoscope includes a bell-type face and a membrane-type face. When the bell-type face is in contact with the skin, the force is relatively light, and it is used to listen to low-frequency sounds. frequency tone. [0003] During use, the doctor needs to listen to the sound sources of different frequencies of human organs, so as to comprehensively analyze and diagnose the symptoms of the patient. In order to listen to the sound sources of different frequencies, for the traditional stethoscope, the doctor must repeatedly rotate the listening head. During the process of listening to the head, the stethoscope will be removed from the human body, which greatly affects the doctor's hearing and judgment. At the same time, the operation is very inconvenient, which affects the doctor's diagnosis to a certain extent. [0004] The...
