| Abstract: | The authors propose a device for following up the kinetics of the fibrin clot enlargement in the plasma. Coagulation is induced by contact activation with a fragment of an arterial wall put into the plasma. Besides the initial time of clot formation, the device helps assess the rate of clot growth. Two phases of contact-induced clotting may be distinguished. The first is slow activation of the clotting system and formation of minor amounts of fibrin, the other is rapid growth of the clot, with the linear increment of the clot size being constant during 15 min. |
