The 3M Littmann Classic II Infant Stethoscope is specially designed for use on infant patients and delivers high acoustic sensitivity, through its dual-side chest piece, for both high and low-frequency sounds. A specially engineered 1-inch floating diaphragm and 3/4 inch bell are designed for capturing high and low frequencies respectively. With specially sized diaphragms, these stethoscopes by Littmann are used by students and medical professionals alike to identify, listen to, and study heart, lung, and other body sounds for physical assessment and diagnosis in infant patients. Resilient tubing folds tightly for pocket portability and retains its shape while patented Snap Tight Soft-Sealing Eartips help form an effective acoustic seal. The anatomically correct headset is angled to channel sound and enhance listening comfort while the nonchill rim and diaphragm provide patient comfort. The classic Littmann stethoscope is made in the USA. The Littmann classic ii stethoscope and package are latex-free and come with an alternate pair of small ear tips and instructions. Stethoscopes are diagnostic instruments that amplify sounds made by the body from the heart, lungs, abdomen and intestinal tract, or other body sites. A stethoscope is used to detect and study internal systems, such as fetal development, blood flow or blood pressure (BP), and respiration, and sounds, such as cardiac, venous, arterial, pulmonary, and uterine. This is ideal and versatile stethoscope cardiology to invest in.
