Background

A blood coagulation analyzer is a clinical laboratory apparatus for analyzing the coagulation and anticoagulation, fibrinolysis and antifibrinolysis functions of a patient's blood.

The main detection methods of the prior clinical blood coagulation analyzer comprise an optical method and a magnetic bead method, wherein the two methods have the advantages and the disadvantages respectively, and the optical method is to detect the change of the turbidity of a sample to be tested in a test cup by utilizing the optical principle. The method has the advantages that an optical information curve in the testing process can be output, so that more valuable judgments can be given to results and instrument states compared with a magnetic bead method, and meanwhile, the optical method is adopted by most full-automatic coagulation analyzers due to low cost and easy automation realization. However, the optical method has very high requirements on the design of the light path, and the small deviation of the detection light path of the existing full-automatic blood coagulation analyzer can cause the difference of the inter-channel measurement results, thereby affecting the inter-channel consistency of the full-automatic blood coagulation analyzer, greatly affecting the overall measurement result of the blood sample, and causing that the correct measurement result cannot be obtained.
