Littmann Select Tunable Diaphragm Stethoscope(Black)

The 3M™ Littmann® Select Stethoscope is a dependable clinical tool for taking blood pressure readings and performing limited physical assessments. It delivers reliable sound quality and the portable convenience of a single-sided chestpiece at an affordable price.Tunable diaphragm technology—a 3M invention—lets medical professionals hear different frequency sounds by simply adjusting the pressure on the chestpiece. Unlike two-sided models, there’s no need to turn over and reposition the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time-saving feature allows the healthcare provider to focus on the patient, while the non-chill rim provides patient comfort.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.Resilient next-generation tubing retains its shape and flexibility even after folding tightly into a pocket. It provides longer stethoscope life due to improved resistance to skin oils and alcohol, and is less likely to pick up stains. Next-generation tubing is not made with natural rubber latex, a benefit to sensitive medical professionals and their patients. And, to play its part in the protection of human health and the environment, the next-generation tubing does not contain phthalate plasticizers.The Select stethoscope is made in the USA for consistent quality. It comes complete with large soft-sealing ear-tips and instructions.Wide diameter aerospace alloy / Anodized aluminum‎.
