3M Littmann Master Cardiology Stethoscope DOCTORS and CARDIOLOGIST STETHOSCOPE

Offering a tunable diaphragm, dual-lumen tubing and a precision ergonomically designed chestpiece, the 3M™ Littmann® Master Cardiology™ Stethoscope is designed to give you the best acoustic response in the Littmann mechanical stethoscope line.

The outstanding acoustics of our 3M™ Littmann® Master Cardiology Stethoscope can help you assess patients and make decisions confidently – even with hard-to-hear sounds such as gallop rhythms, murmurs, and rubs. Designed to provide excellent sound quality, these stethoscopes are made in the USA with globally-sourced materials and feature tunable diaphragm technology so you can hear low- and high-frequency sounds without repositioning or turning over the chestpiece. The dual-lumen tubing eliminates the rubbing noise of traditional double tubes and the adjustable headsets and snap-tight soft-sealing ear tips ensure an excellent acoustic seal and comfortable fit.

The 3M™ Littmann® Master Cardiology™ Stethoscope 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 healthcare 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 stethoscope 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 health and the environment, the next generation tubing does not contain phthalate plasticizers.
