SPRAGUE UPGRADE
Sprague X
The MDF® Deluxe Sprague Rappaport X Stethoscope with X-configuration dual-lumen acoustic tubing is an advanced Sprague Rappaport design used by healthcare professionals. Similar to the MDF® Sprague Rappaport, it is five stethoscopes in one for adult, pediatric, and infant patients and is traditionally trusted to detect faint heart sounds and murmurs. The innovative, patented X-configuration tubing eliminates the rubbing of traditional Sprague Rappaport dual tubing that can cause acoustic interference.


CONVERTIBLE CHESTPIECES
Sound Check 1-2-3
Using the included accessory kit, the adult and pediatric diaphragm assemblies can be removed and replaced with adult, pediatric, and infant bells.
TRUE BELL & TRUE DIAPHRAGM
Sound Judgement
Take the guesswork out of auscultation with our True Bell & True Diaphragm dual-head chestpiece. The bell side focuses on low frequency sounds (20Hz-100Hz) while the Ultra-sensitive Diaphragm handles high frequencies (100Hz-1000Hz).

Lightweight.

ERGONOMAX™ HEADSET
Sound Fit
Our patented ErgonoMax™ headset is pre-angled and tension adjustable, allowing for a tailored fit. The dual-leaf spring adds a second layer of durability, ensuring the structural integrity of the headset and prevents breaking when tension is increased.

DENSER, LONGER TUBING
Sound Barrier
Constructed of latex-free PVC, the patented A2X is an A-Type redesigned with an X configuration and dual input. It maintains two sound transmission channels to preserve acoustic integrity while sealing out extraneous sounds, even in high-noise conditions. The thicker, denser PVC construction prevents cracking and wearing.
