Stethoscope Parts and Functions
- Ear Tubes (Binaurals): Metal tubes connecting ear tips with flexible tubing; angled for optimal ear canal fit; some models allow rotation for comfort.
- Ear Tips: Fit directly into the ear canal; designed for individual ear sizes to ensure comfort and effective sound transmission.
- Tubing: Comprises the yoke (upper segment) connecting to ear tubes, while the lower, non-forked section attaches to the chest piece.
- Diaphragm: Flat, drum-like component used to detect high-pitched sounds; essential for assessing specific types of body noises.
- Bell: Cup-shaped part utilized to listen for low-pitched sounds; critical for detecting certain heart sounds and murmurs.
- Chest Piece: Features either a bell or diaphragm, often both; serves as the contact point for sound collection from the body.
- Orientation of Ear Tubes: Designed to be pointed toward the nose for correct alignment and optimal sound quality.
