The Yuyue stethoscope is equipped with two multifunctional flat earpieces and three bell-shaped chest earpieces of three different sizes, which can be converted in five different ways. The Yuyue stethoscope is designed as a universal, bell-shaped chest listening head of three different sizes, which is attached to the original two diaphragms, both large and small, thus forming a complete device. Each diaphragm or bell base can Suitable for various specific needs. The large and small dual-function flat listening head is used to detect low-frequency heart sounds, expansion sounds, third heart sounds, first and second heart sounds, and high-quality buzzing sounds (murmurs) emitted by the heart. The small face can detect high-quality natural sounds in young children. Heart sounds. The large bell-shaped listening head can accurately diagnose low- and mid-range heart sounds and buzzing sounds. The medium bell-shaped listening head is suitable for checking the low-mid-range heart sounds of infants and children and the buzzing sounds made by children, and is particularly sensitive. To use a stethoscope correctly, you must first wear it correctly. How to correctly wear the Yuyue 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 put the ear tube 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 wearing method is correct, but the tightness between the ear sinus and the ear canal is not good, and the auscultation effect is not good, please pull the ear tube outward to adjust its elasticity. Improper wearing method will cause poor auscultation effect when the ear sinus and ear canal are not tightly connected. For example, if the ear tube is worn backwards, you will not be able to hear. How to clear stethoscope debris? If the Yuyue stethoscope has been kept in a pocket or has not been maintained regularly, lint, fibers or dust from clothing may block the ear tube of the stethoscope. Regular maintenance and cleaning can prevent the above situations from happening. Check for tightness when using the Yuyue stethoscope. The high-quality sound transmission effect of a stethoscope is related to the tightness between the stethoscope and the patient's body surface, and between the stethoscope and the listener's ear canal. Loose earpiece parts, loose Y-tube, or damaged Y-tube will affect the tightness. The better the tightness, the more accurately the sound from the patient's body can be transmitted to the listener's ears. So check the status of your stethoscope frequently. Double-sided stethoscope: When using a double-sided stethoscope, the user needs to switch between the bell side or the membrane side of the earpiece. When the membrane face is in use, the clock face will be closed to avoid interference. vice versa.
