Function

Allows user to hear sounds from within the body. Especially used to listen to heart, pulse & lungs.

Technical

Improved stethoscope designed by George P. Cammann of New York introduced in 1855 is very similar to this design. The large bell-shaped chest piece was often held before the patient's mouth while the chest was percussed, to amplify "cracked pot" sound. Smaller chest pieces were used for ordinary auscultation. [Ref. 4] George Tiemann was the first to manufacture the Cammann stethoscope. This example was probably produce c. 1860 or later: it features longer flexible tubes attached by gutta percha connectors to the binaural ear tubes. The two parts of the instrument could be detached for carrying: this example could not be detached at time of cataloguing. [Ref. 5]
