1. A device for applying compressive pressures against a patient'"'"'s limb from a source of pressure, comprising:

  • a sleeve for placement about the patient'"'"'s limb and having at least one inflatable chamber;

    means for controlling intermittent inflation and deflation of said chamber;

    first conduit means connecting the controlling means and said chamber;

    second conduit means having two free ends and having one end communicating with the first conduit means at one of said free ends, upstream from said chamber and sleeve and downstream from, but adjacent to, said controlling means;

    means for determining pressure communicating with said second conduit means at the second of said free ends; and

    means for providing resistance against fluid flow passing through the second conduit means intermediate the first conduit means and the pressure determining means, said first conduit means communicating directly with said chamber at a location downstream from the connection of the second conduit means with the first conduit means whereby, by virtue of the location of said second conduit and pressure determining means, pressure in said chamber may be read directly but remotely therefrom without need of directly connecting a pressure determining means onto said chamber.
