 Dual Head, Traditional Style MD One Stethoscope, Headset, Eartip, Chest Piece, Safety Lock Eartip Adapters

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.
