Prothrombin time measuring apparatus with means to start the timer in response to the initial decrement of optical transmissivity

摘要: A coagulation meter including automatic means for maintaining the test temperature at 37* C. photocell is used to sense change in turbidity of contents a cuvette. The started by voltage output produced when final component injected into cuvette and ended caused clotting. time between these two events measured digital circuit display automatically actuated differentiation detector circuit.
