Description

External-discharge type electronic stethoscope

Technical Field

The utility model relates to medical equipment, in particular to an externally-placed electronic stethoscope.

Background

An electronic stethoscope is an electronic device that helps a doctor to auscultate the breath sounds of a patient. The principle is that the sound inside the body of the patient is converted into an electric signal through the stethoscope head, amplified and digitally processed, and then transmitted to the doctor through the ear tube. The device adopts the modern electronic technology, can amplify the sound and improve the definition of the sound, so as to help doctors to better hear the sound of internal organs such as heart, lung and the like and perform more accurate diagnosis. Meanwhile, the electronic stethoscope can also record sounds in the auscultation process, so that doctors can reference and compare in subsequent diagnosis and treatment.

At present, electronic stethoscopes can only hear sounds through devices such as ear tubes or headphones, because these devices can effectively reduce interference of external noise to the hearing experience. However, this also causes drawbacks, such as the inability to use an electronic stethoscope to listen to vital signs such as heart beat sounds or respiratory sounds of the patient while the physician is wearing the protective garment, which can affect the diagnostic and therapeutic results. Furthermore, listening to the sound with the ear tube may also be inconvenient for the physician, who has to insert the ear tube into the ear and remain relatively stationary during operation, which may affect their comfort and working efficiency. Further, in a noisy environment such as a hospital, the noise may interfere with the doctor hearing the patient's internal sound, thereby affecting the diagnostic result. Thus, the use of electronic stethoscopes still faces some challenges and limitations, requiring further technical improvements and innovations to address these issues.
