Fundamental purpose of the present utility model is the above-mentioned shortcoming overcoming existing product existence, and a kind of flat in vitro diagnostic reagent pick-up unit is provided, the synchronization of detection sample can be ensured and avoid sample to volatilize, the accuracy of detection efficiency and detection can be improved simultaneously, this pick-up unit can the microslide of simultaneously loading different size, effectively reduces manual operation cost.
The purpose of this utility model is realized by following technical scheme.
The utility model flat in vitro diagnostic reagent pick-up unit, comprises flat body; It is characterized in that, this flat body is that polymethylmethacrylate (PMMA) is integrally moulded; One-body molded recessed several reaction bench in the plane of this flat body, the end face of this reaction bench is provided with several sample application zone, two inside sidewalls that reaction bench is corresponding are respectively equipped with corresponding loading convex body, and the loading convex body top of the correspondence that two inside sidewalls that this reaction bench is corresponding are respectively equipped with is fitted together to for microslide.
Aforesaid flat in vitro diagnostic reagent pick-up unit, wherein, in described flat body plane, the recessed several reaction bench of one are equidistant setting, and the transversal section of this reaction bench is rectangle, this rectangular length is equal with microslide length, and rectangular width equals microslide width; Several sample application zone that described reaction bench end face is provided with are that double parallel is equidistantly arranged.
Aforesaid flat in vitro diagnostic reagent pick-up unit, wherein, described loading convex body is step convex body, and the height of this step convex body is 1 ± 0.5mm, and the width of step convex body is 2 ± 0.5mm.
Aforesaid flat in vitro diagnostic reagent pick-up unit, wherein, several sample application zone that described reaction bench end face is provided with are the shrinkage pool that the double parallel corresponding with the envelope antigen area size on microslide and position is equidistantly arranged, and the degree of depth of this shrinkage pool is 1 to 0.5mm.
The beneficial effects of the utility model, this pick-up unit can ensure the synchronization and the detection efficiency that detect sample, contacted with the inserted type of reaction bench by microslide, form leakproofness structure, effectively avoid the volatilization of loaded sample, because envelope antigen region on microslide is corresponding with the position detecting sample application zone, can guarantee that antigen and sample effecting reaction improve the accuracy rate detected; Because every block pick-up unit can comprise multiple sample application zone, and each sample application zone is independent setting, thus greatly can improve detection efficiency.
