The present invention relates to an auscultation device and an auscultation system thereof, and more particularly to an auscultation device that can be instantly shared and an auscultation system for the same.

Stethoscope is a medical instrument used to assist in the diagnosis of human physiological conditions. By listening to the physiological sounds naturally emitted by the human body, such as the sounds of internal organs or tissues such as heart sounds, lung sounds, and abdominal sounds, doctors can diagnose abnormalities in the human body.

The structure of the stethoscope can be roughly classified into a sound pickup component, a conductive component, and a listening component. The pickup component is a commonly known auscultation head or probe for being close to the human body to collect physiological sound. The conductive component is used to conduct the physiological sound from the sound pickup component to the listening component in any form. The earliest stethoscope uses a rubber hose as a conductive component to restrict the sound wave to the inside of the rubber tube. Today, the electronic stethoscope is physiological. The sound is converted into an electronic signal. The doctor can listen to the physiological sound transmitted by the pickup component through the listening component. The listening component is generally a sealed sinus ear to prevent the external noise from interfering with the interpretation of the physiological sound.

However, the conventional stethoscope can only be used and listened to by one person at a time. When auscultation teaching or medical staff is required to cooperate with the treatment, the conventional stethoscope cannot allow all the people to simultaneously receive the patient's physiological sound when only one person auscultates. . Although some manufacturers have proposed a solution, they use a loudspeaker such as a horn as a listening component to directly play the human physiological sound obtained by auscultation. However, in addition to infringing the privacy of the patient, this method sometimes has too much environment. The noise will also affect the doctor's judgment of listening to the physiological sound. In addition, the physiological sound played will also disturb the peace of others. Moreover, when the method is followed up or taught, the lecturer cannot allow all the listeners to simultaneously, immediately and clearly hear the patient's physiological sound and the dictation of the lecturer, thereby invisibly reducing the listener, especially the student. Learning outcomes.
