MDF ProCardial ERA Lightweight Cardiology Dual Head Stethoscope
with Adult, Pediatric, and Infant-Neonatal Convertible Chestpiece

The MDF® ProCardial ERA™ is the very first stethoscope of its kind. We promise, you’ve never seen a stethoscope like this. It is a stethoscope completely reinvented and you won’t believe how light it is. Redesigned lightweight headset and patented sound-sealing A2X tubing, it features a convertible chestpiece with 3 real bells and 3 separate diaphragms in adult, pediatric, and infant modes. Enhanced by 10 unique patents, the precisely handcrafted ProCardial ERA™ abolishes the age-old dichotomy by proving a true high-performance stethoscope can also be lightweight. The ProCardial ERA™—a true paradigm shift.

MDF ProCardial ERA Lightweight Cardiology Dual Head Chestpieces

The patented handcrafted lightweight aluminum dual-head chestpiece is precisely machined and hand polished for the highest performance and durability. The patented dual-output, full-rotation acoustic valve stem features SoundTight™ GLS technology to seal in sound, and the green indicator dot allows the user to easily identify the active sound channel. The chestpiece comes fitted with real bells and diaphragms in adult, pediatric and infant sizes allowing for quick conversions to nine different configurations. Each diaphragm features a non-chill retaining ring to provide a secure acoustic transmission for heart and lung sounds of 100Hz to 1000Hz, and the cardiology bells are crowned with non-chill bell rings to provide greater sound amplification and isolation of low frequencies (20Hz to100 Hz).
