Abstract
This paper presents a design for a digital thromboelastograph (TEG). The instrument design is based on the principle of a couette viscometer. The device measures shear elasticity of blood during clot formation. The recording mechanism comprises a two-channel light-beam deflection system and a recording system based on a charge-coupled-device (CCD) array. An 8-bit CMOS microprocessor (NSC800) supervises data acquisition from the CCD array. The two-channel system produces a record on a thermal printer allowing one to observe the time course of coagulation and simultaneously compare two different blood specimens.
