Cross matching instrument

Abstract

The invention discloses a cross matching instrument. Before blood transfusion, professional testers are required to complete blood group testing and cross matching experiments in a professional laboratory. The cross matching instrument of the invention comprises a support frame, a reagent suction and adding mechanism, a first serum storage box, a second serum storage box, a physiological saline storage box, a low ionic medium storage box, a polybrene solution storage box and a suspension storage box. The reagent suction and adding mechanism comprises a reagent disc, layered collectors, layeredextraction tubes, a polybrene medium reagent addition tube, and serum addition tubes, wherein the bottom surface of the reagent disc is provided with six mounting holes uniformly distributed along the circumferential direction of the axis of the reagent disc; the six mounting holes are all blind holes, and the bottoms of the six mounting holes are all fixedly provided with permanent magnet steel;and the tops of the polybrene medium reagent addition tube, the three layered collectors and the two serum addition tubes are each embedded with an adsorption block. The cross matching instrument ofthe invention can assist medical staff in completing blood group testing and cross matching experiments, and greatly simplifies the workload of the medical staff in the process of blood matching.

Description

technical field [0001] The invention belongs to the technical field of blood detection, and in particular relates to a cross-matching instrument. 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 patients. Some hospitals r...

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
