3M Littmann Master Cardiology Stethoscope - Navy Blue 2164

The 3M Littmann Master Cardiology Stethoscope, model 2164, is a high-performance acoustic stethoscope designed for advanced diagnostic auscultation. It is engineered to deliver superior sound quality, facilitating the detection of subtle physiological sounds. The stethoscope features a single-sided chestpiece that incorporates a tunable diaphragm, allowing for the differentiation of high and low-frequency sounds by simply adjusting the pressure applied to the patient's skin.

This feature is crucial for detailed cardiac and pulmonary assessments. The dual-lumen tubing is a key innovation, creating two independent sound channels within a single external tube. This design effectively prevents the acoustic interference and rubbing noise often associated with traditional double-tubing configurations, ensuring clearer sound transmission.

The headset is designed for ergonomic comfort and precise fit, with angled eartubes that are anatomically shaped to align with the natural curvature of the ear canals, further enhancing acoustic seal and reducing ambient noise intrusion. The overall length of the stethoscope is 69 cm, providing adequate reach for patient examinations. The navy blue tubing offers durability and a distinct visual identifier.

This model also includes a special procedures adapter, expanding its utility for auscultating smaller patients, such as pediatric or neonatal individuals, where precise sound capture is paramount. The construction utilizes robust materials to ensure longevity and consistent performance in demanding clinical environments. This stethoscope is intended for use by medical professionals who require exceptional acoustic fidelity for critical diagnostic decisions.
