Size of chest piece cover: D1 (adult) 47MM, D2 (children) 38MM, D3 (bell type) 28MM; length of ear piece plus rubber tube: L 650MM.

This stethoscope features several patented designs (Patent Number: 200620001001.9, 200530169863.1, 200520122864.7, 200520122862.8).

Manufactured with stainless steel and patented multi-channel spin shaft seal design which enables it to rotate in 120ˇăinterval to select an appropriate chest piece cover, this stethoscope is intended to be used for auscultation of high and low hear sounds and fetal heart sound as well as regular auscultation of adults and children.
The stethoscope consists of 3 different chest piece covers for auscultation of high and low heart sounds, childrenˇŻs heart sound and fetal heart sound respectively. Sound-collecting cavity of stethoscope features a patented design of high and low tunes, which enables doctors to hear sound of either high or low tune with the same chest piece cover simply by adjusting the force on the stethoscope, resulting a sensitive switching between the two sounds.
