Microtube column agglutinatior agglutination assay result identification system and blood grouping analyzer

Abstract

The invention relates to the technical field of medical equipment and discloses a microtube column agglutinatior agglutination assay result identification system. The microtube column agglutinatior agglutination assay result identification system comprises an image acquisition module, a microtube image capture module, a target area acquisition module, an effective reactant area capture and identification module, a standard setting module and a judgment output module. Boundary lines on the inner wall of a microtube are automatically fit out through a binarization processing unit and a fitting tracing unit, a reaction area within the boundary lines on the inner wall of the microtube are acquired to serve as a target analysis area, so that analytical judgment cannot be interfered by the image part beyond the area, and the identification accuracy is effectively improved; meanwhile, the microtube column agglutinatior agglutination assay result identification system is suitable for various microtube column agglutinatiors with different specifications, and the university of the microtube column agglutinatior agglutination assay result identification system in analyzers with different specifications is improved; and brightness position and relative area combined classified judgment is performed on the effective reactant area in the target analysis area, and contrast analysis is performed on rough classification and fine classification, so that the result identification accuracy is further improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a microcolumn gel card agglutination detection result recognition system and a blood type analyzer. Background technique [0002] At present, clinical blood testing generally adopts the cassette detection method with simple operation, clear results and stability. To control the size of the gel gap, so that the gap can only allow free red blood cells to pass through, so that free red blood cells and aggregated red blood cells are separated. The detection principle is: when the antigen and antibody react, the blood cells agglutinate, and when centrifuged, the agglutination cannot pass through the gap of the gel, but stays in the upper layer of the gel tube, and the reaction is positive. Unagglutinated blood cells can pass through the gel gap during centrifugation and settle at the bottom of the gel tube, giving a negative reaction. [0003] In an automated blood analyzer, t...

Problems solved by technology

However, the above-mentioned method of directly intercepting the image of the reaction area of ​​a fixed size in the microtube for analysis is only applicable to a certain size of the microcolumn gel card. When the width of the microcolumn gel card used is different, the intercepted reaction area It is not comprehensive, or the interception area is too large, which may affect the final analysis results and cause misjudgment.
