3M™ Littmann® Master Classic II™ Stethoscope

Stethoscope is acoustic medical device. Its hearing to the internal sounds of ours body. It typically has a small disc-shaped resonator that is placed against the chest, and two tubes connected to earpieces. We are mainly using it to here lung and heart sounds. It is also used to listen to intestines and blood flow in arteries and veins. In combination with a sphygmomanometer, it is commonly used for measurements of blood pressure. Less commonly, "mechanic's stethoscopes" are used to listen to internal sounds made by machines, such as diagnosing a malfunctioning automobile engine by listening to the sounds of its internal parts. Stethoscopes can also be used to check scientific vacuum chambers for leaks, and for various other small-scale acoustic monitoring tasks. A stethoscope that intensifies auscultator sounds is called phonendoscope.
