1. How to install the stethoscope
The stethoscope is designed with a patented ergonomic ear tube and ear sinus that conforms to the angle of the ear canal. It fits comfortably into the listener's ear canal without making you feel tired or uncomfortable. Before putting the ear tube on, please pull the ear tube of the stethoscope outward; the metal ear tube should be tilted forward, and the ear tube should be inserted into your external ear canal so that the ear sinus and your ear canal are tightly closed; the size of each person's ear canal They are all different, and you can choose the right size for your ear sinuses.
If the ear tube is worn correctly but the tightness between the ear sinus and the ear canal is poor and the auscultation effect is not good, please pull the ear tube outward to adjust its elasticity. When the ear sinus and ear canal are not in close contact, incorrect wearing methods can lead to poor auscultation. For example, when the ear tubes are worn backwards, there is no hearing at all.
2. How to use a stethoscope
1. Place the binaural earpieces in your ears and hold the earpieces to the desired position for auscultation.
2. Choose the listening headset you need according to different needs.
3. Place the binaural receivers in your ears.
4. If you gently tap the diaphragm with your hand, you will hear a sound, so you can confirm that the stethoscope is ready for use.
5. If you cannot hear the vibration of the diaphragm when you tap it with your hand, please rotate the earpiece to 180° and hear a click, indicating that it is in place and facing the opposite side. Then, tap the diaphragm again with your hand and you will hear a vibration, which means the stethoscope is ready for use. At this point, you can use your stethoscope to diagnose the patient you are examining.

Precautions for using a stethoscope:
1. Check before using the stethoscope. As an important clinical medical equipment, stethoscopes need to be strictly inspected before use. The first thing is to remove debris from the machine, because the stethoscope may not be used for a long time, and debris will appear in the ear canal. These debris will directly affect the sound transmission in the ear canal, so regular cleaning and maintenance are necessary.
2. Another point is to check the tightness of the stethoscope, because the sound information collected from the patient needs to have good air tightness as a guarantee to better help the doctor make judgments. If there is looseness at the Y interface or ears, maintenance and adjustment should be carried out in time.
3. In addition to external sound interference, stethoscopes and headphones used under normal circumstances have some similarities, so they will also face the headphone effect. The so-called headphone effect refers to the noise produced when the unit parts rub against the body and other external objects, interfering with the listener's hearing.
