Safety Lock™ Eartip Adapters
Prevents accidental injury to the ear canal from loose eartips coming off during your practice.
Our patented SafetyLock eartip adapters lead the industry in user safety by creating a larger surface area on which the eartip sits. Most stethoscopes just have a 3mm gauge headset where the eartip sits. If the eartip comes off this can easily puncture your inner ear. The MDF® SafetyLock™ system rests on a 5mm gauge headset and provides ample surface area to prevent this.
Clear Silicone Eartips
One size does not fit all. Our ComfortSeal®, crack-resistant, eartips come in 3 sizes to ensure optimal comfort and sound insulation. It's Silicone construction is Latex-Free and clear for hygienic purposes.
Many stethoscopes use 3mm thick aluminum tubing which tends to kink and even break. Our 5mm stainless steel tubing is much more durable and nearly impossible to even bend under normal conditions.
Denser, Longer Tubing. Better Sound.
Our flexible, latex-free tubing is thicker and longer to block out environmental sounds and provide a safer distance between you and your patient. The patented Acoustic Pyramid Chamber™ is located in the acoustic tubing below the spring to keep the tubing channel open for maximum sound transmission to the headset.
The number one purpose of a stethoscope is sound transmission. Many stethoscopes use less dense and weaker tubing which also tends to kink where the tube meets the headset. Always make sure your stethoscope is designed for optimal sound quality.
True Bell & True Diaphragm
Take the guesswork out of auscultation and benefit from our True Bell & True Diaphragm dual-head chestpiece. Clearly marked by our green indicator dot, let the Bell side take care of the low frequency sounds (heart & murmurs) while the Diaphragm side handles the high frequencies (lungs and breath).
Our most popular metal design in the MD One line, this stainless steel plating has a mirror finish giving it a vibrant and luxurious look.
