3M™ Littmann® Master Cardiology™ Stethoscope

The 3M™ Littmann® Master Cardiology™ Stethoscope has the best acoustic response of all mechanical stethoscopes in the Littmann family. It features an adjustable dual-frequency membrane, an integrated double-lumen tubing system, and a precise, ergonomic stainless steel chestpiece.

The adjustable dual-frequency membrane technology, a 3M invention, allows medical professionals to control the membrane's response to different frequency ranges by varying the chestpiece's pressure. Unlike two-sided models, there is no need to turn or reposition the chestpiece. For low-frequency sounds, lightly press the chestpiece on the patient; for high-frequency sounds, increase the pressure on the chestpiece. This time-saving feature allows the medical professional to focus more on the patient, while the cold protection ring provides maximum comfort for the patient. The tension of the ear tubes can be easily adjusted by squeezing or pulling them apart to suit individual needs. The soft-sealing ear tips conform to the ear for excellent acoustic sealing and comfortable wear. The ear tips fit tightly onto the ear tubes, so some force is required to remove them for safety reasons. The next-generation tubing material is durable and retains its shape and flexibility even when stored in pockets. It ensures a longer life for the stethoscope, as it is more resistant to skin oils and alcohol and less prone to contamination. The tubing material does not contain natural rubber latex or phthalate plasticizers, benefiting medical professionals and patients with sensitive skin. The Master Cardiology Stethoscope is made in the USA to ensure consistent high quality and comes complete with large and small soft-sealing ear tips and instructions.

Recommended for a wide range of diagnostic uses, including heart, lung, and bowel sounds in the field of diagnostic medicine.
