This single instrument can be used for both adults and children! The pediatric diaphragm can be changed to a bell.

In addition, it has an integrated diaphragm with a small step between the rim, making it easy to clean. [Suspended Diaphragm] It uses a suspended diaphragm that allows auscultation of both low and high-frequency sounds on the same side. Adult side/pediatric side: Suspended diaphragm that allows auscultation of both low and high-frequency sounds on the same side. Auscultation of low-frequency sounds can be achieved by pressing lightly, and high-frequency sounds by pressing firmly. It uses a new, thicker single tube that is more resistant to sebum. There is a groove on the handle of the chest piece, which allows you to identify the auscultation surface. Please rotate the chest piece so that the groove faces the side you want to auscultate.
