Cammann binaural stethoscope, presented by Cammann to Dr. Barth.
The stethoscope is used on the chest or another part of the body to listen to organs such as the heart or lungs. The sounds can help diagnose the patient’s problem. This binaural stethoscope was presented to Dr Barth by its designer Dr George P. Cammann. Cammann was an American physician. It was made by George Tiemann and Company in New York.
The familiar Y-shaped binaural stethoscope was developed in the 1850s. It has rubber tubing going to both ears. Before this date, physicians used a single tube stethoscope. The first were developed by French physician Rene Theophile Laennec (1781-1826) in 1816.
