MDF 777 MD ONE Stethoscope for internal medicine, navy (MDF4)

Long cable, reversible head with open funnel.
Longer cable than other stethoscopes - the 777 model has an extremely long cable, which enables examination of the patient even in difficult conditions. It is made of high-density material - does not stick, does not fall apart, does not contain latex. Double-sided head - the traditional shape of the double-sided head, a fully rotating acoustic valve, the presence of an open funnel and a diaphragm allow listening to low and high tones.
Ultra sensitive membrane.
The diaphragm is made of ultra-sensitive sound-amplifying fiber. Perfect tightness of the membrane is ensured by the membrane retention ring, which creates optimal amplification and a high frequency of heart and lung transmission at frequencies of 100 to 1000 Hz. The membrane is convex with a durable support ring made of non-cooling PVC material for greater patient comfort.
Excellent acoustic improvement.
Large Funnel - Extra large funnel with non-cooling ring provides excellent acoustic enhancement and isolation of low frequency sounds.
Innovative technologies - ErgoMax. 
Other technical advantages that affect the comfort of use are the specially patented design based on two spring leaves hidden in the ErgoMax lyre cable. Thanks to this solution, the stethoscope better adapts to the shape of the head, thanks to which the user feels less pressure. It is very important during an intense and tiring working day or night.
ACP pyramidal acoustic chamber.
Another solution is the Acoustic Pyramid Chamber (ACP), a patented steel-aluminium-shaped chamber in a pyramid, located in the acoustic pipe under the spring springs, responsible for opening the acoustic line at the branch point and maximizing the flow of sound to the headphones.
