ABSTRACT:
The invention provides a method and apparatus for measuring the coagulation of blood. The principle thereof is to detect, at the beginning of coagulation, the stopping of a stream of corpuscles established in a measurement tube (1), the detection being accomplished by means of photoelectric cells or similar (15, 16). A processor (17) allows the measurement of the coagulation rate to be made automatically and displayed. The corpuscles may be microscopic gas bubbles (12) or gains of a powder having a high degree of wettability.
