Sample injector for cross matching of blood, ABO and RhD blood-type identification and screening of irregular antibodies

Abstract

The invention relates to medical experimental apparatuses and particularly relates to a sample injector for cross matching of blood, ABO and RhD blood-type identification and screening of irregular antibodies. The sample injector is provided with a horizontal storage pipe and is characterized in that at least two measuring cups are arranged in the storage pipe in a side-by-side manner; dischargingpipes are arranged at the bottom parts of the measuring cups and penetrate out of the storage pipe downwards; each discharging pipe is provided with a valve A; the storage pipe is externally providedwith a fixed frame; the lower ends of the discharging pipes penetrate out of the fixed frame; the storage pipe is provided with a liquid feeding hose and a liquid discharging hose which are respectively communicated with the storage pipe; a reagent bottle is arranged at the other ends of the liquid feeding hose and the liquid discharging hose. The sample injector has the beneficial effect that the problems that no special sample injector exists for the current blood transfusion and cross matching of blood, ABO and RhD blood-type identification and screening of the irregular antibodies, the adopted common suctioning pipe or dropper is very complex in operation, low in efficiency and easy in error generation.

Description

[0001] This application is a divisional application of the invention patent application with the application number 2017106406027, the application date is July 31, 2017, and the invention title is "Cross-match and ABO and RhD blood type and irregular antibody screening sampler". technical field [0002] 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 [0003] 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 recipie...

Problems solved by technology

[0005] 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
