Background

The medical stethoscope can be used for listening heart sounds, blood vessel murmurmurs, respiratory sounds and the like, the stethoscope can be used for measuring blood pressure, and the stethoscope is also a necessary tool for judging vital signs such as heartbeat and blood pressure. The traditional stethoscope transmits sound through a rubber tube, and unamplified sound is easy to attenuate during transmission. To solve this problem, electronic stethoscopes with amplified sound have been invented. The existing electronic stethoscope uses an electronic audio amplifying circuit, and the amplified electric waves are restored into sound waves through an earphone or a loudspeaker, so that the amplified sound wave signals in the human body are obtained. The existing electronic stethoscope has the advantages of amplifying sound and storing the sound, and can even see the waveform of sound waves through a display screen, and some electronic stethoscopes can also realize remote auscultation. For example, chinese patent application No. 201080041341.3 sets forth "electronic stethoscope for telemedicine applications". Although, the technical scheme of the utility model uses the electronic audio amplifying circuit and the network to realize remote auscultation. However, the electronic stethoscope has a common problem with the existing electronic stethoscopes, namely, the electronic stethoscopes need to be connected with electronic equipment such as earphones through wires, and the use of the electronic stethoscopes is inconvenient due to factors such as dragging of the wires.

The utility model has the following advantages:

because the electronic stethoscope head is constructed in a unitary structure with the housing, all the parts are disposed in the housing, and the circuit of the circuit board is connected to the speaker circuit or the wireless transmitting element, or the circuit of the circuit board is connected to the speaker circuit and the wireless transmitting element. Therefore, the utility model not only has compact structure, but also can selectively realize the following functions:

1. when the circuit of the circuit board is connected with the loudspeaker circuit, the doctor can hear the sound from the electronic auscultation head through the loudspeaker;

2. when the circuit of the circuit board is connected with the wireless transmitting element, a doctor can listen to the sound from the electronic stethoscope head by using a wireless receiving element such as a mobile phone;

3. when the circuit of the circuit board connects the speaker circuit and the wireless transmitting element, the doctor can hear the sound from the electronic stethoscope head by using a wireless receiving tool such as a mobile phone, and can hear the sound from the electronic stethoscope head by the speaker.

In summary, when the wireless auscultation is realized, no wire or catheter is needed between the doctor and the electronic auscultation head, so that inconvenience of dragging and the like caused by connection of the wire or the catheter is eliminated.

Further advantages of the utility model will be given in the examples.
