Automatic cross-match blood tester for unknown blood type

Abstract

The invention discloses an automatic cross-matching tester for bloods with unknown types. Blood group detection and blood cross matching experiments need to be completed by professional testers in a professional laboratory before blood is transfused. The tester comprises an upper shell, a lower shell, needle releasers, hemostixes, thimble devices, a reagent sucking and adding mechanism, a pedestal, a centrifuging test mechanism, blood matching test tubes, a microscope camera, extracting tube grippers, a test tube gripper for test, a blood receptor test tube gripper, a test tube storage box, anextracting tube storage box, a waste test tube collecting box and a waste extracting tube collecting box. The centrifuging test mechanism comprises an upper disc, a supporting disc, a centrifuging rotating shaft, a positioning rotating shaft and a lifting shaking assembly. The reagent sucking and adding mechanism includes a reagent tray, layered collectors, condensed amine medium reagent stores,serum guiding tubes, a normal saline storage box, a first serum storage box and a second serum storage box. The tester can automatically complete blood group detection and the blood cross matching test, and reduces the workload of medical staff in the blood matching process.

Description

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

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
