Blood cross matching tester of unknown blood type

Abstract

The invention discloses a blood cross matching tester of an unknown 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. The tester comprises an upper shell, a lower shell, a reagent sucking and feeding mechanism, a base, a centrifugation test mechanism, a blood matching tube, a microscope camera, an extraction tube claw, a test tube claw, a receptor test tube claw, a test tube storage box, an extraction tube storage box, a waste test tube 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 tester for unknown blood types. Background technique [0002] When performing blood transfusion therapy on a patient, the blood type of the patient must first be known, and then the cross-matching test must be used to further confirm that there is no antigen-antibody reaction of blood type incompatibility between the blood recipient and the blood donor, so as to ensure the blood transfusion of the recipient Safety. 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 blood type detection and cross-matching functions, 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 patient...

Although there are instruments with blood type detection and cross-matching functions, 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. Some hospitals rarely use these instruments in practice

This can only be done by professional testers in professional laboratories to complete blood type testing and cross-matching tests, and the testing process is relatively cumbersome, and there are human errors, which will be very unfavorable to the treatment of patients
