Embodiment Construction

[0025] The following structural drawings and embodiments further illustrate the present invention.

[0026] like figure 1 , 2 shown.

[0027] A method for realizing a wireless stethoscope based on bluetooth technology, which comprises the following steps:

[0028] First, install a piezoelectric sensor on the auscultation head;

[0029] Secondly, the mechanical vibration of the patient's heartbeat is converted into an electrical signal through a piezoelectric sensor;

[0030] Thirdly, the above-mentioned electrical signal is sent to a signal amplification circuit for further amplification after being filtered by a filter circuit to obtain an amplified electrical signal;

[0031] Fourth, send the amplified electrical signal to a bluetooth transmitting module to convert it into a sound signal and transmit it;

[0032] Fifth, use the bluetooth earphone to receive the sound signal emitted by the aforementioned bluetooth transmitting module to obtain the heart sound signal of t...

Abstract

The invention aims to solve the problems like inconvenient use, large interference and small volume caused by the present acoustic rubber tube attached to the stethoscope and discloses a method for realizing wireless stethoscope based on bluetooth technology and a bluetooth stethoscope based on the method. The stethoscope comprises a piezodielectric transducer, a filter circuit, an amplifying circuit, a bluetooth adaptor U2 and a bluetooth earphone, wherein the piezodielectric transducer, the filter circuit, the amplifying circuit and the bluetooth adaptor are integrated to the stethoscope head, the piezodielectric transducer connects with the input end of the filter circuit, the output end of the filter circuit connects with the amplifying circuit, the output end of the amplifying circuit connects with the input end of the bluetooth adaptor U2 and the output end of the bluetooth adaptor U2 connects with the bluetooth wirelessly. It has simple structure, clear signal and can be implemented easily and used conveniently.

Description

technical field [0001] The present invention relates to a wireless electronic stethoscope and its implementation method, in particular to a method and device for realizing the wireless stethoscope by using bluetooth technology, in particular to a bluetooth technology-based wireless stethoscope implementation method and the bluetooth stethoscope. Background technique [0002] At present, when the traditional medical stethoscope auscultates the heart sounds, although the cost is low and the method of use is simple, there are some disadvantages. For example, the traditional stethoscope has no amplification function, and only transmits the sound to the doctor's ear through the rubber trident tube. Make a diagnosis; and its trident tube is easy to be subjected to the friction and collision of clothes and arms to generate noise, which is not conducive to the doctor's accurate diagnosis; the earplugs used in traditional medical stethoscopes have less sound leakage, but plugged in ...
