The LD Prof-III is a neonatal stethoscope for doctors, consisting of a dual head with a plastic membranous diaphragm and an open bell, connecting tube, double tubes, and listening earpieces. It is designed for listening to the heart, lungs, vessels, and gastrointestinal system in newborns.

The bell is used with light pressure to listen to low-frequency sounds, while the diaphragm is used with increased pressure to listen to high-frequency sounds. The switching and adjustment of the function between the functional parts (bell and diaphragm) is done by rotating the valve 180 degrees. When the diaphragm is open, the bell is closed, preventing sound transmission through the bell and vice versa.

SMALL DIAPHRAGM TUBE

The functional diameter of the diaphragm is 20 mm. The diaphragm is equipped with a transparent plastic membrane.

SMALL OPEN BELL

The bell features an elastic contact ring. The diameter of the bell is 18 mm.

Y-SHAPED MEDICAL TUBING

The 56 cm medical tube connects the metal ends with the functional parts (diaphragm and bell). The tube is made of durable, resistant yet flexible plastic material for easy handling.

LISTENING EARPIECES

The soft white listening earpieces offer high comfort, sealing, and durability. Their surface undergoes special treatment that increases slip, reducing dust and lint adhesion.

CLINICAL VALIDATION

Clinically validated by the BHS - British Hypertension Society.
