Instrument for ascertaining degree of chest expansion.
By William R. Warner
-
An instrument, proposed by Dr. Richard Quain, for measuring the extent of movement of the walls of the chest, as a means of diagnosis in thoracic diseases. It consists of a flat case, not unlike a watch-case, having on its upper surface a graduated dial and index, which is acted on by a simple mechanism. A silk cord, long enough to surround one-half the chest, passes through an aperture in the case. The dial is graduated into fifty equal parts, each of which represents the 1-200th of an inch. In using the instrument, the dial is placed firmly against the spine, and the point of the tape over the sternum, or at any other spot according to the part to be examined. The extension of the string, as indicated by the dial, shows the amount of elasticity of the parietes of the thorax. Under the name Thoracom’eter, Dr. Sibson has described an instrument of his invention, which is employed with a similar view as the stethometer of Dr. Quain. -Med. Chir. Transact., vol. xxxi.
