Stethoscope Tips
How to install a Non-Chill Ring from the Chestpiece of a MDF® Instruments Stethoscope
Has your non-chill ring become dirty or cracked? All the free stethoscope parts you need are offered under our Free-Parts-For-Life program! Your non-chill ring is a protector for the low frequency side of your stethoscope. When examining patients, having a cold touch from the chest piece is prevented with the non-chill ring.
To put on your non-chill ring on to the stethoscope, locate the edge of the non-chill ring that sticks out slightly further than the other side it will look longer and it will taper down to a more narrow side fit it over the Bell side of the stethoscope and stretch over to fit. Work your way around fitting the larger edge of the non-chill ring up over the bell and secure into place.
