3M Littmann Cardiology IV Stethoscope - Plum with Smoke Finish 6166

The 3M Littmann Cardiology IV Stethoscope is a diagnostic instrument engineered for superior acoustic clarity and versatility. It features a double-sided chestpiece constructed from precision-machined stainless steel, designed to provide enhanced audibility of both high and low-frequency sounds. The adult side, when firm pressure is applied, offers improved detection of high-frequency sounds, while the pediatric side can be converted into an open bell by replacing the diaphragm with a non-chill sleeve, expanding its diagnostic capabilities.

This conversion makes the pediatric side suitable for smaller patients or for auscultating specific anatomical areas. The stethoscope incorporates a single-piece tunable diaphragm on both the adult and pediatric surfaces, facilitating easy removal, attachment, and cleaning due to their smooth, crevice-free design. The overall construction is ergonomic, with a chestpiece that is 40% larger and 60% deeper than that of the 3M Littmann Classic III Stethoscope, contributing to its high-performance acoustic profile.

The instrument is 69 cm (27 inches) in overall length and weighs 177 grams. The tubing is made from next-generation materials that offer increased resistance to skin oils and alcohol, thereby extending its lifespan and maintaining its aesthetic appearance. This advanced tubing technology also includes a dual-lumen design, which integrates two sound paths within a single tube.

This configuration effectively eliminates the artifactual noise generated by the friction of traditional double tubes, allowing for clearer transmission of patient sounds with reduced interference. The headset is designed for adjustable fit and comfort, ensuring proper seal and acoustic integrity. This model is presented with a plum-colored tube and a smoke-finish chestpiece.

It is manufactured in the USA and is supported by a seven-year international warranty, providing users with extended assurance of its durability and performance. An additional pair of soft-sealing ear-tips and a non-chill sleeve are included in the package.
