Title:
SYSTEM AND METHOD FOR NONINVASIVELY EVALUATING A LIMB SUSPECTED OF COMPARTMENT SYNDROME
Document Type and Number:
WIPO Patent Application WO2003034899
Kind Code:
A3
Abstract:
A system and method are disclosed for noninvasively diagnosing limb compartment syndrome by measuring a quantitative modulus of hardness. A nonmovable pressure probe (36) mounted in the center of a movable spring loaded platform (34) is applied against a limb compartment. Force is gradually applied to the probe and the platform, compressing a limb compartment. Pressure on the probe is measured by a load cell (56) as the probe pushes into the limb. The spring loaded platform displaces and the distance of the probe tip to the platform is measured by an encoder (46). This distance is the depth of compression into the limb by the probe. The relationship of incremental pressures in the probe tip to the platform for each pressure is plotted. A linear regression analysis is performed whose slope forms a quantitative modulus of hardness.
