MDF 777I INFANT Pediatric stethoscope, navy

The best acoustic performance for nursing infants.
MDF 777 I INFANT is a newborn stethoscope adapted for adults and newborns. A hand-held stethoscope with a deliberately lowered stainless steel head ensures the best acoustic performance when examining the smallest patients. 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 fiber membrane.
The diaphragm is made of ultra-sensitive sound-amplifying fiber. The perfect tightness of the membrane is ensured thanks to the membrane safety 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.
Lira Ergomax.
Other technical advantages that affect the comfort of use is a special patented design based on two sheets of springs hidden in the ErgoMax lyre cable. Thanks to this solution, the stethoscope better adapts to the shape of the head, so the user feels less pressure. It is very important during an intense and tiring working day or night.
ACP acoustic chamber.
Another solution is the Acoustic Pyramid Chamber (ACP), a patented chamber in the shape of a steel aluminum pyramid, located in the acoustic tube under the spring springs, responsible for opening the acoustic line at the branch point and maximizing the flow of sound into the headphones.
