Monaural stethoscope. A Piorry-type stethoscope made of wood and ivory; wooden body is cylindrical with a flared, trumpet tip; the base of the cylindrical body is an ivory base. This device is operated by fitting the funnel shaped end of the stethoscope to the patient’s body, and the narrow column to one’s ear to hear a patient’s heart or lungs. The first stethoscope was created by Rene Theophile Hyacinthe Laennec using rolled-up sheets of paper placed against one’s chest and the other end to his ear. Laennec’s research on stethoscopes began in 1817 at Hospital Necker. The Piorry-type stethoscope was developed by Pierre Adolphe Piorry in 1828. See full catalog record for this item.
