A clot test under a uniform shear field in vitro has been designed, which utilizes a concave-convex cone system. A sample of beagle blood was sheared between a stationary convex cone and a rotating concave cone. Evaluation of clot growth was derived from the clotting ratio, which was calculated from the rate of increase of frictional torque between the two cones. The results show that clot grows smaller with increase of shear rate in the range from l00 to 500 s-1.
