Abstract

The mechanical device to be described was originally intended to answer the following question: What might be the physiologic effect of a wave of circular compression applied to the periphery of the body in the direction of the venous flow? It was hoped that a purely mechanical drive of the contents of the peripheral veins, acting as might a heart for these vessels, would assist in the solution of certain problems connected with the pressure back of them—in the capillary and arterial bed. A discussion of the subject with specialists in that branch of medicine revealed, moreover, the extent to which the profession is in need of information on this point. Experiments with the apparatus in question have been in progress now nearly three years. From both a theoretical and a practical point of view the effects, as will be seen, are sufficiently striking and important to deserve the attention
