Description

"3M™ Littmann® Stethoscopes offers the high quality that medical professionals expect, and each replacement part and accessory meets the same demanding standards. Conveniently packaged in kits that correspond to our stethoscope models, Littmann stethoscope replacement parts and accessories make repairs simple. Each item is carefully manufactured to work seamlessly with existing equipment. 3M Littmann Stethoscope Spare Parts Kit – Black, Compatible with Classic III™, Cardiology IV™, CORE Digital, Includes Eartips, Adult & Pediatric Diaphragms, Non-Chill Bell Sleeve, 40016 contains a black single piece tunable diaphragm for both the adult and pediatric sides of the chestpiece, a non-chill bell sleeve, and two small (1/2 inch), Black Snap Tight Soft-Sealing Eartips. Tunable diaphragm technology—a 3M invention—lets clinicians hear different frequency sounds by simply adjusting the pressure on 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 both adult and pediatric patients. 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."

  • Never disappoints.
Good to have. Fits well.

  • Perfect, easy, quick replacement diaphragms for my Cardiologist IV scope, great price
Perfect replacement. You likely already know this but this kit comes with both large and small diaphragms for the Cardiology IV (and III + others as well), as well as 2 replacement ear pieces, and a "non-chill bell sleeve". My scope was missing the large diaphragm for some reason, and while I didn't mind using the small/peds side, it was of course best to fix it. The large diaphragm was as easy to put on my scope as pushing the cap on a ketchup bottle. The edges of the diaphragm are soft and simply slide over the edge of the bell. Takes all of 3 seconds. The appearance is exactly as the original, because it is an OEM replacement after all. Functional, perfect size, all is well in my work world now. ... show more

  • Four 1/2 starts
The product doesn’t look original but fits perfectly I am not sure if the transmission of the cardiac sounds are the same like the original. Recommended

  • Perfect fit for Cardiology II
These fits my old Cardiology II perfectly. It’s really old. Early 1990s. I had contacted Littmann but was told they no no longer support this model. Very happy to find these so I don’t have to buy a whole new Littmann.
