Abstract
Coagulation is detected in a fluid sample such as blood which has been inserted into a cartridge and operated on by an actuator mechanism. The cartridge may be of either of two types: a plunger sensor cartridge wherein a plunger assembly is reciprocated in a predetermined manner within the fluid sample and the descent of the plunger assembly is sensed to determine coagulation conditions, and a gas flow cartridge wherein gas is passed through the fluid sample to transmit liquid in bubbles and the accumulation of the coagulating liquid from the bubbles is sensed to detect coagulation. An actuator mechanism operates with either one or both types of cartridges to create the conditions under which coagulation can be detected and to sense the coagulation detection conditions. The actuator mechanism reciprocates the plunger assembly and forces gas through the liquid sample to create the bubbles.
