Embodiment Construction

[0009] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0010] As shown in the accompanying drawings, the wireless stethoscope avoiding cross-contact includes a stethoscope head 1, which includes a sensor 3, an amplifier circuit 4, a filter 5, a signal output device 6, and a wireless transmitter 7 that are sequentially connected in pairs by communication. In addition, it also includes a 2.4G wireless earphone 2 adapted for wireless communication with the wireless transmitter 7 of the stethoscope head 1 .

[0011] The working principle of the present invention is: when the doctor examines the patient, he uses the auscultation head 1 corresponding to the hospital bed and the 2.4G wireless earphone 2 on the ear, and then collects the sound signal of the measured part through the sensor 3 of the auscultation head 1, and sends it to the amplifier. The circuit 4 amplifies the sound signal, and after being filtered by a fil...

Abstract

The invention relates to a wireless stethoscope for preventing cross-contact. The wireless stethoscope comprises a sensor, an amplifying circuit, a filter, a signal output device and an auscultation head with a wireless transmitter, every two of which are in communication linkage in sequence. The wireless stethoscope further comprises a 2.4 G wireless earpiece which is in wireless communication adaptation with the wireless transmitter (7) of the auscultation head. Since the individual parts of the 2.4 G wireless stethoscope are in a wireless connection, a doctor can work without the limitation of the length of the sound guide tube of the stethoscope. Besides, the auscultation head is given to a patient and one hospital bed is provided with one auscultation head, so that a doctor can use the auscultation head at the head of the hospital bed of the individual patient when performing auscultation on different patients, thereby preventing cross-contact. Therefore, the wireless stethoscope not only maintains the advantages of the electronic stethoscope but also protects the patients and the doctor.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a wireless stethoscope which avoids cross contact. Background technique [0002] Current clinical stethoscope is made up of parts such as natural vibrating membrane auscultation head, sound guide tube, earplug. As a diagnostic tool, the stethoscope needs to be in contact with doctors for a long time. Most doctors carry it with them. When checking the patient's condition, the same auscultation often needs to contact different patients. There is a risk of infection in this cross-contact. Moreover, due to the distance limitation of the sound guide tube, the doctor is often close to the patient's face during auscultation. For the immunocompromised and critically ill patients, the doctor may bring them germs, while for patients with infectious diseases and respiratory diseases , they may bring germs to doctors. Therefore, the appearance of a stethoscope that ...
