Dual-wavelength multi-point test structure and method for automatic coagulation analyzer

Abstract

The invention provides a dual-wavelength multi-point test structure and method for an automatic coagulation analyzer. Compared with the existing test mechanism of the multi-channel automatic coagulation analyzer, the test modules in the invention do not need to be installed together to facilitate installation due to multiple fixed points; the adopted dual-wavelength multi-point metering is suitable for testing test discs of multiple test positions without limiting the volume of the test discs to improve the test efficiency; the first fixed metering point, the second fixed metering point, and the third fixed metering point all use the light of 450nm wavelength, and the fourth fixed metering point uses the light of 650nm wavelength, to apply more resources to projects with higher frequency of use, which makes resource allocation more reasonable, and further improves the detection efficiency.

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dual-wavelength multi-point testing structure and method for an automatic coagulation analyzer. Background technique [0002] The patient has a normal blood coagulation mechanism to ensure the success of the surgical operation. It is also an important basis for hemostasis and coagulation diagnosis and treatment in the Department of Internal Medicine. The normal blood coagulation function of the human body is a physiological function necessary to maintain life. , The formation of fibrin clots consists of three basic factors.

[0003] Coagulation analyzer is one of the important equipment for coagulation test. Currently, the commonly used measurement methods are: (1) coagulation bead method, which uses the electrical signal generated by cutting the magnetic force line during the swing of the magnetic bead to monitor the swing amplitude of the magnetic bead. When the swing amplitude of the magnetic beads decays to 50%, the coagulation end point is determined; however, this detection method needs to add magnetic beads for each detection, which leads to the defects of complicated detection method and high detection cost; (2) optical method, according to the plasma coagulation process The change of turbidity is used to measure the coagulation function, which is simple to operate and has high detection accuracy, which is obviously better than the magnetic bead method; the optical test method generally needs to add an optical test module, such as a four-channel coagulation analyzer, which uses four sets of optical test modules. In this way, it is willing to complete the test of four samples at the same time during the blood coagulation test. However, in this test mode, one set of optical test modules corresponds to one sample, and the test position cannot be moved basically during the test. The test of the current sample must be When completed, the next new sample to be tested can be carried out
