Coupling type blood coagulation testing system and method

Abstract

The invention discloses a coupling type blood coagulation testing system and method. The system comprises a light source device, a coupling device used for collecting light to be tested, emitted by the light source device and illuminating an objected to be measured, a measuring device used for measuring an optical signal of the object to be measured and a controller used for controlling the lightsource device and processing the optical signal of the object to be measured; the coupling device comprises an optical fiber coupling regulation component, first beam splitting optical fibers, a dodging device and second beam splitting optical fibers which are connected in sequence; the optical fiber coupling regulation component is connected with the light source device and is used for regulatinga distance between the first beam splitting optical fibers and the light source device; and the second beam splitting optical fibers are connected with the measuring device. As the distance between the first beam splitting optical fibers and the light source device is regulated by the optical fiber coupling regulation component, the optical fiber coupling efficiency is maximized; and dodging is performed on the light to be tested through the dodging device, the consistency of each testing channel is improved.

Description

technical field [0001] The invention relates to the field of in vitro diagnosis, in particular to a coupled blood coagulation test system and method. Background technique [0002] The current automatic coagulation analyzers in the market generally use the magnetic bead method and the optical method to detect samples. Compared with the magnetic bead method, the optical method has the advantages of low cost and complete test items, and is adopted by most instrument manufacturers. method. Among them, optical methods can be divided into transmission optical methods and scattering optical methods according to the principle of optical testing. The optical transmission method uses a tungsten-halogen lamp as a light source, and adopts a filter + wheel structure to couple monochromatic light of different wavelengths into the splitting fiber, and the end of the splitting fiber irradiates the sample for measurement. Due to the use of 5 kinds of filters, when testing the same project,...
