MDF 747 Dual Head burgundy MDF17

The MDF 747 DUAL HEAD stethoscope for internal medicine is an in vitro diagnostic medical device. Very lightweight stethoscope, designed for all healthcare professionals. The adjustable lyre is made of chrome-plated brass. The extremely lightweight double-sided head made of anodized aluminium and chrome-plated brass provides good acoustic performance and traditional auscultation methods through the diaphragm and funnel. The membrane is made of ultra-sensitive sound amplifying fibre. Perfect membrane tightness is ensured by the membrane retention ring, which produces optimal amplification and high frequency heart-lung transmission at frequencies of 100 to 1000 Hz. A very large funnel with a non-cold ring provides excellent acoustic transmission and isolation of low frequency sounds. The diaphragm is convex with a durable support ring made of non-hardening PVC material for greater patient comfort.
