Stethoscope

This device is a Stethoscope, a non-invasive acoustic medical instrument used primarily for auscultation, or listening to the internal sounds of a human or animal body.

It consists of ear tubes (binaurals), a flexible rubber or PVC tubing, and a chestpiece. The chestpiece typically has a diaphragm for high-frequency sounds (like lungs) and a bell for low-frequency sounds (like the heart). It is an indispensable tool for healthcare professionals, allowing them to monitor heart, lung, and bowel sounds to diagnose various conditions. The device is a fundamental symbol of medicine and patient care.
