MDF MD One Stethoscope

Constructed from acoustically-superior stainless steel, the MDF® MD One™ Stethoscope delivers accurate auscultation of heart, lung, and sounds with acoustic integrity and clarity. An ergonomic design ensures comfort for the doctor and patient, even during extended use. The MD One™ is a premier diagnostic instrument with unmatched performance, durability, and aesthetics.

MDF Instruments uses materials that comply with all local regulations to ensure that all of our products are non-toxic, latex-free, non-phthalate, non-hazardous, etc. to both the medical and the patient communities.

MDF MD One Chestpiece

The handcrafted stainless steel dual-head chestpiece is precisely machined and hand polished for the highest performance and durability. The full-rotation acoustic valve stem with green indicator dot allows the user to easily identify the active sound channel and seals in sound. The chestpiece is fitted with an ultra-sensitive diaphragm sealed with a non-chill retaining ring to provide a secure acoustic transmission. The extra large bell, crowned with a non-chill bell ring, provides greater sound amplification, isolation of low frequencies, and patient comfort.

Comfortseal™ eartips

ComfortSeal™ eartips are phthalate-free and clear for hygienic purposes made of soft silicone in three sizes:small, regular, and large for great fit.

Ergonomax™ headset and Safetylock™

Hand polished, pre-angled stainless steel headset features a patented internal dual-leaf spring construction for durability. Patented SafetyLock™ eartip adapters lead the industry in user safety.

Acoustic Tubing

Constructed of thicker, denser, latex-free PVC, the Y-configuration 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. The longer-than-average length allows a comfortable space between health professional and patient.

Acoustic Pyramid Chamber™

A patented internal metal-alloy chamber located in the acoustic tubing below the spring keeps the tubing channel open for maximum sound transmission into the headset.

Included Accessories

  • 2 extra sets ComfortSeal™ eartips
  • spare ultra-sensitive diaphragm
  • ID tag
