Littmann Cardiology IV Stethoscope by 3M

The 3M™ Littmann® Cardiology IV™ Stethoscope provides a single-piece tunable diaphragm on each side of the chestpiece. Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove. It is used by specialists and general practice physicians, critical care nurses, EMTs, medical students, and other healthcare professionals to identify, listen to, and study cardiac, lung, and other body sounds in adult and pediatric patients.
