3M Littmann Cardiology IV Diagnostic Stethoscope, Black-Finish Chestpiece, Black Tube, Stem and Headset, 27 inch, 6163 Cardiology Stethoscope  (Black)

The 3M Littman cardiology iv stethoscope is the next generation of one of the most recognized stethoscopes in the profession, offering improved acoustic performance with better audibility of high-frequency sounds (adult side, firm pressure). Its distinctive chalice-shaped chest piece features tunable diaphragms on both sides to deliver outstanding acoustic performance, diagnostic versatility, and convenience for treating adult and paediatric patients. The paediatric side of the chest piece converts to a traditional open bell by removing the tunable diaphragm and replacing it with the included non-chill bell sleeve. Both the adult and paediatric sides of the chest piece have single-piece diaphragms that are easy to remove, attach and clean because the surfaces are smooth and without crevices. Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the ear tubes. Snap-tight, soft-sealing ear tips conform to individual ears for an excellent acoustic seal and comfortable fit. Ear tips snap firmly onto the ends of the ear tubes and, for safety, require a significant effort to remove. Dual-lumen tubing combines two sounds paths in one tube, eliminating the rubbing noise that traditional double tubes create. This feature makes it possible for the clinician to hear patient sounds with less interference. 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 clinicians and their patients. And, to play its part in the protection of human health and the environment, the next-generation tubing is not made with phthalate plasticizers.
