Pinard horn
Stethoscope used to listen to the heart rate of a fetus / From Wikipedia, the free encyclopedia
A Pinard horn is a type of stethoscope used to listen to the heart rate of a fetus during pregnancy. It is a hollow horn, often made of wood or metal, about 8 inches (200 mm) long. It functions similarly to an ear trumpet by amplifying sound. The user holds the wide end of the horn against the pregnant woman's abdomen, and listens through the other end.[1]
