Problems solved by technology

[0003] Existing coagulation analyzers use halogen lamps as the light source, and adopt the method of filter wheels, which are sequentially arranged in the optical path to form monochromatic light and irradiate the sample, but the filter wheel Movement must rely on stepper motors and drivers, which not only increases the cost, but also increases the risk of movement structure jamming

Abstract

The invention discloses a two-way light splitting blood coagulation test device. The device comprises a base plate and a first light source device arranged on the base plate. The base plate is successively connected to a light collecting device for collecting polychromatic light emitted by the first light source device, a light splitting device for dividing the polychromatic light into monochromatic light with different wavelengths, a light guiding device for conducting the monochromatic light to a test area and a first measuring device for measuring the optical signal of an object to be tested. The light splitting device comprises a two-way light splitting component so as to realize the multi-project detection of a sample. The polychromatic light is converted into the monochromatic lightwith different wavelengths to be detected through the light splitting device and the light guiding device, and a motor and a driver which filter rotation wheel movement in a traditional blood coagulation analyzer depends on are eliminated. Working is reliable and cost is low.

Description

technical field [0001] The invention relates to the field of in vitro diagnosis, more specifically, it relates to a two-way spectroscopic blood coagulation testing device. Background technique [0002] At present, the automatic coagulation analyzers in the market generally use the magnetic bead method or 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. [0003] Existing coagulation analyzers use halogen lamps as the light source, and adopt the method of filter wheels, which are sequentially arranged in the optical path to form monochromatic light and irradiate the sample, but the filter wheel Movement must rely on stepper motors and drivers, which not only increa...
