Problems solved by technology

[0004] The purpose of the present invention is to solve the three major experiments of blood transfusion safety (blood type cross-matching experiment, ABO positive and negative and RhD blood type identification, and irregular antibody screening) without a special sampler, and the operation of adding samples with ordinary straws or droppers is complicated. Complicated, error-prone, and problems that cannot be checked later, provide cross-matching blood, ABO and RhD blood types and irregular antibody screening samplers

Abstract

The invention relates to the technical field of medical experimental apparatus. Provided are cross-matching of blood, blood types A, B, O, and Rh D, and irregular antibody screening sample-adding machine. The screening sample-adding machine is provided with a distribution pipe with both ends sealed and characterized in that at least one injector is arranged side by side on the distribution pipe; needle parts of the injectors penetrating the distribution pipe are located at the lower end of the distribution pipe; radial through holes are arranged on the injectors inside the distribution pipe; a sample-adding pipe is arranged on the distribution pipe next to each injector; the sample-adding pipes are communicated with the injectors through the distribution pipe. The sample-adding machine solves the problems that sample-adding machines special for cross-matching of blood, blood types A, B, O, and Rh D, and irregular antibody screening experiments do not exist and it is complex, inefficient, and error-prone to operate with ordinary straw or dropper. cross-matching of blood, blood types A, B, O, and Rh D, and irregular antibody screening sample-adding machine are provided.

Description

technical field [0001] The invention relates to medical experiment equipment, in particular to a sampler for cross-matching blood, ABO and RhD blood types and irregular antibody screening. Background technique [0002] So far, the blood transfusion departments of hospitals at all levels have used ordinary plastic straws or plastic droppers to add samples to the three major experiments of blood transfusion cross-matching test, ABO positive and negative and RhD blood type identification, and irregular antibody screening in serum. If the recipient needs blood from more than two donors, the cross-matching test before transfusion is very complicated, and must be carried out between each donor and recipient and between each donor. Cross-matching experiments, such as the two-fork one experiment requires six transparent tubes, and each transparent tube needs to add blood cells and serum once, a total of 12 samples need to be added, and the three-fork one experiment needs to add samp...
