Although there are instruments with the function of cross-matching blood, some instruments have many functions, are inconvenient to operate, and are mostly used for batch testing. In practice, hospitals rarely encounter such a large number of patients. Use less of these instruments
The cross-matching test can only be done by professional testers in professional laboratories, and the testing process is relatively cumbersome, and there are human errors in the operation, which will be very unfavorable to the treatment of patients

Abstract
The invention discloses a blood cross matching method suitable for a known blood type. Before blood transfusion, blood type detection and a blood cross matching test should be carried out in a professional lab by a professional tester. A tester adopted in the method comprises an upper shell, a lower shell, a reagent sucking and feeding mechanism, a base, a centrifugation test mechanism, a test tube, a microscope camera, an extraction tube claw, a test tube claw, a blood receptor test tube claw, a blood donor test tube claw, a test tube storage box, an extraction tube storage box, a waste testtube collection box, and a waste extraction tube collection box. The centrifugation test mechanism comprises an upper disc, a support disc, a centrifugal rotation shaft, a positioning rotation shaft,and an elevating and shaking assembly. The reagent sucking and feeding mechanism comprises a reagent disc, a layered collector, a polybrene medium reagent storing device, a serum conduit, a normal saline storage box, a first serum storage box, and a second serum storage box. The provided tester can automatically finish blood type detection and a blood cross matching test and reduces the workload for the medical workers in blood matching.
Description
technical field [0001] The invention belongs to the technical field of blood detection, and in particular relates to a cross-matching method suitable for known blood types. Background technique [0002] When performing blood transfusion therapy on patients, it is first necessary to confirm through cross-matching blood tests that there is no antigen-antibody reaction of blood group incompatibility between the recipient and the donor, so as to ensure the safety of the recipient's blood transfusion. Now blood transfusion therapy is mainly based on component blood transfusion, and in clinical application, blood plasma and red blood cell transfusion are the most common. Although there are instruments with the function of cross-matching blood, some instruments have many functions, are inconvenient to operate, and are mostly used for batch testing. In practice, hospitals rarely encounter such a large number of patients. Use less of these instruments. The cross-matching test can o...
