Littman IV Cardiology Stethoscope

The 3M Littmann Cardiology IV™ Stethoscope is built for clinicians who require outstanding acoustic performance combined with exceptional versatility. Its innovative design provides better audibility of high-frequency sounds, making it an indispensable tool for critical care environments, cardiology, emergency medicine, and advanced general assessments.

Key Features

• Outstanding Acoustics: Engineered to provide exceptional acoustic performance (rated 9 out of 10) with improved audibility of high-frequency sounds, helping you hear subtle changes in patient status.

• Dual-Lumen Tubing: Two sound paths in one tube eliminate the rubbing noise associated with traditional double-tube stethoscopes, ensuring you hear the patient, not the equipment.

• Tunable Diaphragm Technology: Both the adult and pediatric sides of the chestpiece feature a single-piece tunable diaphragm. Press lightly for low-frequency sounds and firmly for high-frequency sounds.

• Versatile Pediatric Side: The pediatric side easily converts to a traditional open bell by replacing the single-piece diaphragm with a non-chill rim, offering flexibility for varied patient demographics.

• Easy-to-Clean Design: The single-piece diaphragms feature a smooth surface without crevices, making them incredibly easy to attach, remove, and sanitize between patients.

• Next-Generation Tubing: Retains its shape and flexibility even after being tightly folded into a pocket. It is formulated for improved resistance to skin oils and alcohol, extending the life of the instrument.

• Ergonomic Headset: The headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. Snap-tight, soft-sealing eartips provide an excellent acoustic seal and comfortable fit.
