The utility model discloses do the improvement to the light detection district of current structure, the structure of ladder face is designed into to the luminousness detection check of original planar structure, forms two blocks of regions in light detection district and non-functional district for the wall thickness attenuate of light detection district has reduced thickness and overall dimension to the light detection district of 0.25-0.3mm relative original thickness, makes the measurement of reagent luminousness more accurate.
Description
Technical Field
The invention relates to a reagent strip, in particular to a detection reagent strip with an improved CV value.
Background
The detection reagent strip is a common tool for detecting the reagent at present, a pp material is generally selected, a plurality of independent detection lattices are arranged on the detection reagent strip side by side, various physicochemical properties of the reagent need to be monitored and analyzed, one of the detection lattices is used for analyzing the light transmittance of the reagent, the size of the bottom surface of the lattice for detecting the light transmittance in the existing industry is generally a plane of 8mm x10mm, the plane is called as an optical detection area, the wall thickness of the bottom of the optical detection area is thinnest and can only reach 0.48mm, the limitation is mainly caused by the structure of a mould in an injection molding process, and if the wall thickness of the bottom is set to be lower than 0.48mm, the problem is caused by filling of molten plastic in. The detection of the light transmittance is naturally that the smaller the wall thickness of the light detection area is, the better the light detection area is, so that the problem that the technicians in the industry are always troubled by how to reduce the wall thickness of the light detection area on the basis of selecting the same material is solved.
Disclosure of Invention
In view of the above problems, the present invention aims to provide a reagent strip with improved CV value, which improves the light detection region of the existing structure to better and more accurately detect the light transmittance of the reagent.
The invention has the technical scheme that the detection reagent strip with the improved CV value comprises a strip-shaped body, wherein a series of independent detection grids for storing a reagent and detecting the physical and chemical properties of the reagent are arranged on the body along the length direction of the body, the detection grid at one end of the body is a light transmittance detection grid, the bottom surface of the light transmittance detection grid comprises a square light detection area and a non-functional area positioned outside the light detection area, the length and the width of the light detection area are 3-5mm, the thickness of the light detection area is 0.25-0.3mm, and the thickness of the non-functional area is 0.35-0.4 mm.
Preferably, the outer contour of the non-functional region is square and has a size of 8x10 mm.
Preferably, the CV value of the photodetection region is 5% or less.
The invention improves the light detection area of the prior structure, designs the light transmittance detection grid of the prior plane structure into a structure of a step surface to form two areas of a light detection area and a non-functional area, wherein the two areas are respectively connected on a mould by two independent inserts to complete the injection moulding and the mould opening and closing of a product in the injection moulding process, the thickness of the wall of the light detection area can be reduced to 0.25-0.3mm by the improvement of the structure, the thickness and the outline dimension are reduced compared with the light detection area with the prior thickness, and the light transmittance of a reagent can be smoothly produced by injection moulding by matching with the structure of the non-functional area, so that the measurement of the light transmittance of the reagent is more accurate.
