Abstract
The coagulation of blood is measured by introducing the blood into an annular gap in a beaker formed between the inner surface of the beaker and a cylindrical member depending into the beaker. The beaker is mounted on the upper end of a rod-like support. A coil arrangement about the lower part of the rod-like support impresses a circular orbiting motion on the support and beaker. Another core associated with the rod-like support measures changes in amplitude of the support produced by the development of fibrin in the blood sample in the annular gap.
