Embodiment Construction

[0009] figure 1 It is a preferred embodiment of the present invention, which proposes a microfluidic chip device for immune analysis, including a sample injection part 1, a microfluidic chip 3 and a detector 4 with a light source. The sample injection part inputs the sample to be tested and the reaction solution into the microfluidic chip 3 , the sample to be tested and the reaction solution form a reaction mixture in the microfluidic chip 3 , and then the detector 4 measures the reaction mixture. In this embodiment, the determination of urinary albumin content is taken as an example for illustration, but those skilled in the art will understand that the present invention is also applicable to the determination of other urine components or plasma-related components.

[0010] The sampling part 1 includes a sampling part and a sampling valve 12 . The sampling unit can be a micropump sampling unit or a hydraulic sampling unit, and the sampling unit is a sampling pump 11 in this ...

Abstract

The invention relates to a micro fluidic chip apparatus used for immunization analysis, which comprises a sample introduction part, a micro fluidic chip and a detector having light source; the micro fluidic chip comprises a sample introduction zone, a reaction zone and a detection zone, the sample introduction zone provides a mixing micro channel for mixing a sample to be measured and a reaction solution, a bending micro channel with a specific microstructure on the inner wall is provided in the reaction zone for fully mixing the sample to be measured and the reaction solution, a detection micro channel as a detection optical path optical path is provided in the detection zone, a detector light source irradiates a reaction mixed liquor in the detection micro channel for determining the sample to be measured; and the mixing micro channel of the sample introduction zone, the bending micro channel of the reaction zone and the detection micro channel of the detection zone are communicated in order. The invention also provides the above mentioned micro fluidic chip used for determining urinary albumin.

Description

technical field [0001] The invention relates to a microfluidic chip device, in particular to a microfluidic chip device for immune analysis. Background technique [0002] At present, the detection of urinary albumin mostly adopts the immunoturbidimetric method or the immunoscattering turbidimetric method, which is performed on a biochemical analyzer, a spectrophotometer or a specific turbidimeter. The purchase of these instruments and related measurement reagents is expensive, and the cost pressure is high, and the instruments are large and inconvenient to carry around, so the measurement operation must be carried out in a specific laboratory or testing room. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a microfluidic chip device for immunoassay with fast detection and low cost. [0004] A microfluidic chip device for immune analysis, including a sample injection part, a microfluidic chip and a detector with ...
