Product Description ------------------- The 3M Littmann Master Cardiology Stetho is characterized by the best acoustic response in the Littmann mechanical stetho line; with a tunable diaphragm, dual-lumen tubing, and a precision, ergonomically designed, stainless steel chestpiece. The 3M Littmann Master Cardiology Stetho features tunable diaphragm technology—a 3M invention—that lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Unlike two-sided models, there’s no need to turn over and reposition the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time-saving feature allows the care provider to focus on the patient, while the non-chill rim provides patient comfort. Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove. Resilient next-generation tubing retains its shape and flexibility even after folding tightly into a pocket. It provides longer stetho life due to improved resistance to skin oils and alcohol, and is less likely to pick up stains. Next-generation tubing is not made with natural rubber latex, a benefit to sensitive medical professionals and their patients. And, to play its part in the protection of human and the environment, the next-generation tubing does not contain phthalate plasticizers. The Master Cardiology stetho is made in the USA for consistent quality. It comes complete with large and small soft-sealing eartips, large firm eartips, Special Procedures Adapter, and instructions.

Sw between bell and diaphragm modes is as easy as a simple pressure change on the chestpiece so there is no need to remove, index and replace for same-site auscultation. This time-saving feature allows the care provider to 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 Master Cardiology Stetho is made in the USA; product and package are latex-free and come complete with small and large eartips, Special Procedures Adapter, and instructions. What is a Stetho? ---------------------- Stethos are diagnostic instruments that amplify sounds made by the body from the heart, lungs, abdomen and intestinal tract, or other body sites. A stetho 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. Stethos 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 stetho can come as single, double (dual), or triple-head. Binaural stethos are used with both ears, and single stethos work with one ear. Differential stethos are double-head, and allow sound comparison between different body sites. Non-electronic, also called mechanical or acoustic, stethos transmit sound through hollow tubing to a listener’s ear. Stethos are used by students and a wide array of care providers including physicians, nurses, and veterinarians, as well as spets such as cardiologists, pediatricians, troenterologists, pulmonologists, and respiratory professionals in hospital, clinical, or other care facilities.
