3M Littmann Cardiology IV Stethoscope - Hunter Green 6155

The 3M Littmann Cardiology IV Stethoscope is a high-performance acoustic medical device designed for advanced diagnostic auscultation. It features a dual-lumen chestpiece constructed from stainless steel, offering a tunable diaphragm on both the adult and pediatric sides. This innovative design allows for the detection of a wider range of frequencies by simply adjusting chestpiece pressure.

The adult side can be used for both high and low-frequency sounds, while the pediatric side, with its smaller diaphragm, is optimized for smaller patients and for listening to low-frequency sounds. The stethoscope is engineered with a robust, single-piece tunable diaphragm that is easier to clean and less prone to breakage than traditional two-piece designs. The acoustic tubing is made of a next-generation material that is resistant to skin oils, alcohol, and stains, and it is also latex-free, contributing to user and patient safety.

The tubing is a single lumen within a dual-lumen system, meaning there are two sound paths within the single outer tube, which helps to eliminate the rubbing sound that can occur with traditional dual-tube stethoscopes. The headset is designed for comfort and proper acoustic seal, with anatomically angled eartubes and soft-sealing eartips that conform to the ear canal. The overall length of the stethoscope is 69 cm (27 inches).

This model, code 6155, is presented in a hunter green color. The product is backed by a 7-year warranty, reflecting its durable construction and expected longevity in clinical settings.
