Embodiment 1

[0031] Such as figure 1 and 2 As shown, embodiment 1: a kind of electronic stethoscope based on bluetooth, comprises metal face shell 1, and the bottom surface of metal face shell 1 is provided with vibrating diaphragm 2, and metal face shell 1 is provided with a cavity, is installed in the cavity based on bluetooth communication The pickup 3 is provided with a sealing device 4 at the opening of the cavity.

[0032] The pickup 3 includes a bluetooth mainboard 301, which is provided with a high-fidelity audio sensor 302, a lithium battery 303, a USB interface 304, and a bluetooth module 305. The audio sensor 302 , the lithium battery 303 and the USB interface 304 are all connected to the bluetooth main board 301 .

[0033] The Bluetooth listening device (not shown in the figure) is a headset, a speaker, a mobile phone or other audio playback devices.

[0034] Sealing device 4 is a cover type plastic shell (such as figure 1 shown) or handle plastic case (such as figure 2 s...

Embodiment 2

[0040] Such as Figure 3-5As shown, the cavity of the electronic stethoscope is also equipped with a pressure adjustment device, which can adjust the contact area between the vibrating diaphragm and the human body and can timely feedback the adjustment result to the operator through the Bluetooth listening device. In this way, Bluetooth communication not only provides patient auscultation information, but also provides information on whether the stethoscope is used correctly.

[0041] The pressure adjusting device comprises a motor 10, a driving wheel 11, a first driven wheel 12, a second driven wheel 13, a third driven wheel 14, a fourth driven wheel 15 and a belt 16, the motor 10 drives the driving wheel 11 to rotate, and the driving wheel 11 passes through The belt 14 causes the first driven wheel 12 , the second driven wheel 13 , the third driven wheel 14 , and the fourth driven wheel 15 to rotate synchronously.

[0042] The first driven wheel 12 is provided with a throug...

Abstract

The invention relates to an electronic stethoscope based on Bluetooth. The electronic stethoscope comprises a metal face shell, a Bluetooth module and Bluetooth sound listening equipment. A vibrating diaphragm is arranged on the bottom face of the metal face shell, the metal face shell is provided with a cavity, a sound pick-up based on Bluetooth communication is installed in the cavity, and the sound pick-up is in wireless communication with Bluetooth sound listening equipment. The electronic stethoscope based on the Bluetooth is characterized in that a pressure adjusting device is further arranged in the cavity, and the pressure adjusting device can adjust the contact area of the vibrating diaphragm and the human body and can feed back an adjusting result to an operator in time through the Bluetooth sound listening equipment.

Description

technical field [0001] The invention relates to a medical instrument, in particular to an electronic stethoscope based on bluetooth. Background technique [0002] The stethoscope is the most commonly used diagnostic tool for internal and external gynecologists and pediatricians. The traditional stethoscope is mainly composed of a sound pickup part (chest piece), a conductive part (rubber tube) and a listening part (earpiece). [0003] The traditional stethoscope must touch the patient's body through the sound pickup part, and then transmit it to the doctor's ear from the listening part to listen to the sound (heartbeat, breathing, etc.) of the patient's body in real time. In the case of a highly contagious disease (such as new crown, SARS and other infectious diseases), doctors cannot wear a stethoscope after wearing protective clothing, and cannot effectively listen to the sounds of the patient's body; Abnormal sounds are not always produced. In many cases, doctors cannot ...
