Overview
The MDF® Sprague Rappaport Stethoscope is five stethoscopes in one for a full range of diagnostic applications and is traditionally trusted to detect faint heart sounds and murmurs. As the most versatile model on the market, this classic design allows healthcare professionals to assess adult, pediatric, and infant patients using just one stethoscope. An ergonomic design ensures comfort for the doctor and patient, even during extended use.
Chestpiece
The handcrafted gold-plated zinc-alloy dual-head convertible chestpiece is precisely machined for high performance and durability. Full-rotation dual-output acoustic valve stem with green indicator dot allows the user to easily identify the active sound channel. Using the included accessory kit, the adult and pediatric diaphragm assemblies can be removed and replaced with adult, pediatric, and infant bells.
Comfortseal™ eartips
Soft silicone ComfortSeal™ eartips are phthalate-free and clear for hygienic purposes. To ensure proper fit and isolation of sound, MDF® ComfortSeal™ eartips are available in three sizes: small, regular, and large.
ErgonoMax™ Headset and SafetyLock™
Hand polished, pre-angled stainless steel headset features a patented internal dual-leaf spring construction for durability. Patented SafetyLock™ eartip adaptors lead the industry in user safety.
Acoustic Tubing
Constructed of thicker, denser, latex-free extruded PVC, the dual non-stick acoustic tubing provides insulation for superior sound transmission and seals out ambient noise while preventing the cracking and wearing that can occur from repeated use. Dual high-performance acoustic tubes are secured in place by non-pinching, non-obtrusive chrome-plated brass acoustic tube clasps.
Included Accessories
2 extra sets ComfortSeal™ eartips, spare adult and pediatric clear PVC diaphragms, pediatric diaphragm assembly, pediatric bell, infant bell, and ID tag.
