Pinard Horn Obstetrical Stethoscope

This Pinard Horn obstetrical stethoscope was made beginning in 1895. It was the invention of the French doctor, Adolphe Pinard (1844-1934) to listen to an unborn baby's heartbeat. It quickly became the most common obstetrical stethoscope and is still used by many midwives around the world today. It is commonly referred to as just a "Pinard Horn".

This example of the Pinard Horn was made of hard rubber, and was very light—weighing only 1 oz. The length of the stethoscope was 5⅝".

Don't confuse stethoscopes with the shorter ear trumpets and conversation tubes. See General Information—Conversation Tubes for further information on this subject.

View of the bell end of the Pinard Horn obstetrical stethoscope. This is the end that went against the mother's abdomen. The large hollow bell let it "fit" to the curve of her abdomen without rocking which let the doctor hear the best.

The bell was 2⅛" in diameter.
