An automatic cross-matching test method suitable for known blood types

Abstract

The invention discloses an automatic cross-matching testing method suitable for known blood types. Before the blood transfusion, a professional examiner needs to finish a cross-matching test in a specialized laboratory. A tester comprises an upper-part shell, a lower-part shell, a needle ejection device, a hemostix, a needle ejector, a reagent absorbing and adding mechanism, a base, a centrifugaltest mechanism, a blood matching test tube, a microscope camera, an extraction pipe hand claw, a test tube hand claw for the test, a test tube hand claw for a blood receptor, a test tube storage box,an extraction tube storage box, a waste test tube collection box and a waste extraction tube collection box, wherein the centrifugal test mechanism comprises an upper disc, a support disc, a centrifugal rotating shaft, a positioning rotating shaft and a lifting shaking assembly; and the reagent absorbing and adding mechanism comprises a reagent disc, a layering collector, a condensed amine mediumreagent storage, a serum guiding pipe, a normal saline storage box, a first serum storage box and a second serum storage box. According to the method, the blood type detection and cross-matching testcan be automatically finished, and the workload of medical workers in the blood matching process is simplified.

Description

technical field [0001] The invention belongs to the technical field of blood detection, and in particular relates to an automatic cross-matching test 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-mat...

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 a professional tester in a professional laboratory, 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
