Stethoscope Parts A basic, nonelectronic stethoscope consists of a binaural assembly and a chest piece. Ear tubes The binaural assembly includes the following parts: Ear tips (earpieces). The ear tips fit into the external ear canal. They should be an appropriate size for the ear and should fit comfortably. Most ear tips are interchangeable. Ear tubes (binaurals). These are the metal tubes onto which the ear tips and the flexible tubing are fitted. They are angled to fit the ear canal properly. Some eartubes rotate to assure a snug, optimal fit. Tubing. The yoke, or upper portion of the flexible tubing. connects to the ear tubes while the lower, non-forked portion connects to the chest piece. The tubing, either single or double-lumen, transmits sound from the chest piece to the earpieces. Double-lumen tubes tend to be more sensitive to sound. The chest piece is a bell or a diaphragm; many stethoscopes have both. Around the edge of the bell or diaphragm is a ring or sleeve designed to provide a barrier between the metal or hard chest piece and the patient's skin. They are often called "non-chill" rings or sleeves. Bell. A stethoscope's bell is the cup-shaped part that is used for listening to low-pitched sounds. Diaphragm. A stethoscope's diaphragm is the fiat, drum-like part that is used for listening to high-pitched sounds. Ear tips -Tubing Diaphragm Bell
