Embodiment Construction

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

[0026] Such as figure 1 , 2 shown.

[0027] A method for implementing a wireless stethoscope based on Bluetooth technology, which includes 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 electrical signals by piezoelectric sensors;

[0030] Third, the above-mentioned electric signal is wave-filtered by a filter circuit and then sent to a signal amplifying circuit for further amplification to obtain an amplified electric signal;

[0031] Fourth, the above-mentioned amplified electrical signal is sent to a Bluetooth transmitter module to be converted into a sound signal for transmission;

[0032] Fifth, the heart sound signal of the patient can be obtained by using the Bluetooth headset to receive the sound signal transmitted by the aforementioned Blu...

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 invention relates to a wireless electronic stethoscope and a realization method thereof, in particular to a method and a device for realizing the wirelessization of a stethoscope by using Bluetooth technology, in particular to a realization method and a Bluetooth stethoscope of a wireless stethoscope based on Bluetooth technology. Background technique [0002] At present, the traditional medical stethoscope has some shortcomings in auscultating heart sounds, although it is low in cost and simple in use. For example, the traditional stethoscope has no amplification function, but only transmits the sound to the doctor's ear through the rubber trigeminal tube. The sound is weak, and it is difficult to capture some faint but very important biological sounds from the internal organs of the human body, making the doctor unable to timely Make a diagnosis; and its trigeminal tube is easily affected by the friction and collision of clothes and arms to produce no...
