3M Littmann Master Cardiology Stethoscope - Black with Black Chestpiece 2161

The 3M Littmann Master Cardiology Stethoscope is a high-acuity acoustic instrument designed for advanced diagnostic auscultation. It features a single-sided chestpiece constructed from precision-machined stainless steel, ergonomically shaped for comfortable handling and effective sound transmission. The tunable diaphragm technology allows the user to capture both high and low-frequency sounds by simply adjusting the pressure applied to the patient's skin.

This single-sided design simplifies the auscultation process, enabling healthcare professionals to focus on specific sounds without needing to flip the chestpiece. The stethoscope incorporates dual-lumen tubing, which consists of two sound channels within a single external tube. This construction effectively isolates sound paths, preventing the artifactual noise that can arise from the friction of traditional double-tubing designs, thereby enhancing the clarity of transmitted sounds.

The headset is designed for adjustable fit, allowing for personalized comfort and optimal acoustic seal with the eartips. It is supplied with a range of eartip sizes and types, including soft-sealing and firm options, to ensure a secure and comfortable fit for various users and to achieve superior acoustic isolation. Additionally, a special procedures adapter is included, facilitating auscultation on pediatric and neonatal patients.

The overall length of the stethoscope is 69 cm, and it has a net weight of 185 grams. This model is presented with a black-colored tube and a black chestpiece.
