Abstract

The invention discloses a wireless stethoscope, which comprises an auscultation head and an earphone, wherein the auscultation head comprises a shell body, and a sound transducer, a signal processing unit and a wireless signal emitter which are fixedly installed in the shell body, wherein the sound transducer, the signal processing unit and the wireless signal emitter are sequentially connected with one another; the earphone comprises a wireless signal receiver, a digital / analog (D / A) converter and a loudspeaker which are sequentially connected with one another; and the auscultation head and the earphone are wirelessly connected with the wireless signal receiver through the wireless signal emitter. The wireless stethoscope not only can detect the common heat sounds and breath sounds, but also can catch the special heat sounds, lung sounds and bowel sounds, and has the advantages of stability, reliability, high precision and simplicity in operation; the wireless stethoscope also can store the sound data in a memory for bringing convenience for latter lookup, and the data can be applied in teaching; and the wireless stethoscope has the real-time wireless communication function, can realize multiuser union diagnosis, improves the diagnosis efficiency and accuracy, and also satisfies the clinic teaching requirement.

Description

technical field [0001] The invention relates to the field of medical equipment and medical teaching equipment, in particular to a wireless stethoscope. Background technique [0002] Auscultation of heart and lung sounds is the most commonly used method for diagnosing cardiopulmonary diseases and understanding cardiopulmonary function. Although the traditional method of auscultating heart and lung sounds with a stethoscope is simple, it is often difficult to capture some weak but very important biological sounds from the internal organs of the human body, which makes it difficult for doctors to make a timely diagnosis. Especially in harsh environments, such as messy accident scenes, busy emergency rooms and noisy ambulances, it is almost impossible to use traditional stethoscopes for effective diagnosis. Moreover, traditional stethoscopes are equipped with sound-transmitting rubber tubes, which make it very inconvenient to use and have a large problem of interference. Cont...
