How to wear a stethoscope correctly
The stethoscope is designed to meet the ear canal angle of the patented ergonomic ear tube and the ear sinus. It fits snugly into the ear canal of the listener and does not leave you feeling tired and uncomfortable. Before putting the ear canal on, please pull the ear tube of the stethoscope outward; the metal ear tube should be tilted forward, put the ear tube into your external auditory canal, make the ear sinus close to your ear canal; the size of each person's ear canal is different, you can choose the appropriate size of the ear sinus. Improper wearing method, the ear sinus and the ear canal are not close together, which will cause poor auscultation.
If the stethoscope is kept in the pocket or is not regularly maintained, the cotton wool, fibers or dust from the clothing may block the stethoscope ear tube. Regular maintenance and cleaning can avoid the above situation.
Check the tightness
The high-quality sound transmission of the stethoscope is related to the tightness of the stethoscope and the patient's body surface, and the stethoscope to the ear canal of the listener. Loose parts of the head, loose Y tube, and damaged Y tube will affect the tightness. The better the fit, the more accurately the sound in the patient's body can be transmitted to the listener's ear. So check the status of the stethoscope frequently.
