Medical Portable Multifunctional Stethoscope:During cardiac auscultation, the membrane head can listen to high-frequency sounds well, and the cup head is suitable for listening to low-frequency sounds or murmurs. Modern stethoscopes are double-sided stethoscopes. There are both membrane type and cup type on the stethoscope head. The conversion between the two only needs to rotate 180 °. Experts suggest that clinical doctors should use double-sided stethoscopes. Another patented technology is called floating membrane technology. The membrane auscultation head can be changed into a cup type auscultation head in a special way to listen to low-frequency noise. Normal and abnormal lung sounds belong to high-frequency sounds. Only membrane hearing head can be used for lung auscultation.

Listen to the cold ring on your head

During the diagnostic class, the teacher taught to auscultate the patient after holding the head of the stethoscope in his hand for a moment, so as not to stimulate the patient with the cold metal on the stethoscope. The use of cold protection ring on modern stethoscope is more humanized to reduce the stimulation of cold metal to patients.

Earplugs for stethoscope

Professional stethoscope is generally equipped with sealed earplugs with excellent sealing and comfort.

Ear spring of stethoscope

The ear springs of the new stethoscope are made of tough steel, which can be adjusted to the appropriate tightness. It is more comfortable to wear, and it is also convenient to adjust the orientation of the earplugs. Since the ear canal is not completely 90 ° perpendicular to the side, but tilts slightly backward, the earplug should be tilted slightly forward when wearing. The earplug orientation of high-qualityMedical Portable Multifunctional stethoscope can be pre fixed according to the anatomical direction, which is called anatomically correct ear piece.
