Abstract

A stethoscope head is provided with a rigid handle and carries a covering of resilient material, around its periphery, so that it can be used as an auscultation hammer. In the form described the head is circular and is surrounded by a concentric sponge rubber ring of appreciable thickness. A single rigid tube projects radially from the diaphragm chamber and is forked at its outer end for the attachment of flexible ear tubes. The sensitivity of the instrument may be controlled by means of a tapered screw which closes, to any desired extent, a passage leading from the diaphragm chamber to the atmosphere.
