ABSTRACT:
A system for measuring bleeding time in vitro is disclosed in which blood is passed under pressure through a porous element and the resulting volumetric flow is measured. The porous element is provided with a through aperture and supported in such a manner that the blood moves through the aperture and not laterally into the porous element. The porous element can be soaked in a solution, for example, adenosine diphosphate, which coagulates the platelets and in this manner it is possible to reproduce in vivo bleeding conditions.
