Pinard pipe

A Pinard tube is an obstetric stethoscope used to listen to the sounds of the fetal heart. It was developed by Adolphe Pinard in 1895 and is still used today in obstetrics as an alternative to cardiotocography .

The first stethoscopes, which were developed by René Laënnec from 1816 , initially consisted of only a single tube. Laënnec's friend Jacques-Alexandre Lejumeau de Kergaradec was the first to use stethoscopes to auscultate fetal heart sounds . The hearing trumpets were then gradually adapted to the needs of obstetrics (e.g. to avoid too much movement over the maternal abdomen), so that finally Pinard developed the version that is still in use today. Today, Pinard pipes are mostly made of wood.
