ABSTRACT:
A chrono-stethoscope which includes a stethophonic head adapted to detect heartbeats and other bodily sounds. The head is connected to one end of an elongated flexible tubular sound conveyance channel element which carries a detachably mounted timepiece at a location spaced by at least three inches from the stethophonic head. At the other end of the sound channel element, a pair of ear pieces are connected to a main portion of the flexible tubular sound channel element through a bifurcated portion of the channel element which forms a pair of branch tubes. The timepiece is preferably constructed to provide an indication of elapsed seconds of time, and a clip detachably engages it with the tubular sound conveyance channel element.
