Product Description

The 3M Littmann Cardiology III Stethoscope is designed for clinicians who require outstanding acoustic performance combined with exceptional versatility. Its innovative design provides a tunable diaphragm on each side of the chestpiece. The colors shown online are approximations. We have made every effort to show the best possible match to the color of the actual product. However, some variation is expected, due to differences in both lighting and monitor calibration.

From the Manufacturer

The 3M™ Littmann® Cardiology III™ Stethoscope, one of the most recognized stethoscopes in the industry, features tunable diaphragms on both sides to deliver outstanding acoustic performance, diagnostic versatility and convenience for treating adult and pediatric patients. The diaphragm on the small side is easily removable and, with the included nonchill bell sleeve, converts to a traditional open bell for capturing low frequencies. The Cardiology III stethoscope is used by students and medical professionals such as cardiologists, pediatricians, and other healthcare providers to identify, listen to, and study cardiac, lung, and other body sounds in adult, pediatric patients. With innovative tunable diaphragm technology, switching between bell and diaphragm modes is as easy as a simple pressure change on the chestpiece, which means there is no need to remove, index and replace for same-site auscultation or turning over the chestpiece. This time-saving feature allows for focus on the patient. 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 Cardiology III is made in the USA; product and package are latex-free and come complete with non-chill rims for the small and large diaphragms, small and large eartips, 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. Stethoscopes typically have Y-shaped rubber tubing that allows sound to travel from the chestpiece to the eartips. An open bell detects low frequency sounds, and a diaphragm detects high frequency sounds. A stethoscope can come as single, double (dual), or triple-head. Binaural stethoscopes are used with both ears, and single stethoscopes work with one ear. Differential stethoscopes are double-head, and allow sound comparison between different body sites. Non-electronic, also called mechanical or acoustic stethoscopes, transmit sound through hollow tubing to a listener’s ear. Stethoscopes are used by students and a wide array of healthcare providers including physicians, nurses, and veterinarians, as well as specialists such as cardiologists, pediatricians, gastroenterologists, pulmonologists, and respiratory professionals in hospital, clinical, or other healthcare facilities.
