Abstract
An arterial thrombus detection system (4) measures and displays the elapsed times (ET1, ET2, etc.) for an arterial pulse to travel between selected pairs of locations (A and B, B and C) along the length of a patient's limb (10, 12). The arterial pulse sensors comprise inflatable cuffs (A, B, C) with pressure sensors (A, B, C) that are flexibly secured together to form a sleeve (6, 8) which is wrapped around the limb (10, 12). A pair of start/stop timers (46, 48) are controlled in accordance with arterial detection pulses to measure the elapsed times (ET1, ET2, etc.). Display of elapsed times (ET1, ET2, etc.) which are significantly different signifies a thrombus in the section of the limb associated with the relatively longest elapsed time.
