A cross-matching instrument

Abstract

The invention discloses a cross matching blood instrument. Before blood transfusion, professional testers are required to complete blood type testing and cross-matching experiments in professional laboratories. The invention includes 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 ion medium storage box, a polybrene solution storage box and a suspension storage box. The reagent suction and adding mechanism includes a reagent plate, a layered collector, a layered extraction tube, a polybrene medium reagent adding tube, and a serum adding tube. The bottom surface of the reagent tray is provided with six installation holes uniformly distributed along the circumference of the reagent tray axis; the six installation holes are all blind holes, and the bottom is fixed with permanent magnetic steel. The tops of the polybrene medium reagent addition tubes, the three layered collectors and the two serum addition tubes are all embedded with adsorption blocks. The invention can assist medical staff to complete blood type detection and cross-matching test, greatly simplifying the workload of medical staff during the blood matching process.

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
