Embodiment 1

[0035] see Figure 1-8 , taking the situation of two blood donors transfusing blood to a blood recipient as an example, the blood serum and blood cell samples of the blood recipient and the two blood donors are first prepared. This embodiment adopts the sampler containing three syringes and the In patent CN104614538A, the size of the combiner is 3×3. The blood recipient’s serum sample is added to a group of samplers, the blood cells are added to a group of samplers, and the sera of two blood donors are added to a group of samplers. , the blood cells are added to a group of samplers, a total of 6 groups of samplers are needed, and the combiner is placed at the position where the manipulator is operated. The method of adding samples is the same as the second embodiment in the patent CN107247154B.

[0036]After completing the addition of serum and blood cells, shake well and add low-ion buffer, and then the manipulator operates the polybrene adding device 1 to add polybrene reage...

Embodiment 2

[0053] This embodiment is a situation where a blood donor transfuses blood to a blood recipient. When doing a cross-matching test, only three test tubes need to be prepared and placed side by side, and a transition plate 3 is fixedly installed above the three test tubes. The transition plate 3 includes The plate body 301, the top surface of the plate body 301 is provided with liquid inlet holes 304 arranged in the vertical and horizontal directions, and the bottom surface of the plate body 301 is provided with three longitudinal communication grooves 302, each communication groove 302 corresponds to the position of the corresponding longitudinal liquid inlet hole 304, The three communicating grooves 302 are located in the same horizontal row and are respectively provided with a liquid discharge pipe 303; the top surface of the disc body 301 described in this embodiment is provided with four abscissas and three ordinates, and the intersection of the abscissa and the ordinate is a...

Abstract

The invention discloses a package analyzer for detecting blood transfusion compatibility. The package analyzer comprises a serum blood cell sample injector, a test tube combiner and a manipulator foroperating a sample injector to add a sample into a test tube combiner, and further comprises a polyamine adding device and a deflocculating agent adding device. The manipulator can operate the polycondensation amine adding device to add a polycondensation amine reagent into the test tube combiner, the polyamine adding device comprises a fixed frame connected with the manipulator, and a reagent bottle and two injectors are arranged in the fixed frame. A bypass pipe communicated with the bottom of the reagent bottle is arranged at the bottom of each of the two injector needle cylinders, the topsof the push rods of the two injectors are each provided with a sliding support extending downwards, and the two sliding supports are oppositely arranged. The opposite sides of the two sliding supports are each provided with a rack, a servo motor is further installed in the fixing frame, a gear is installed at the output end of the servo motor, and the two sides of the gear are meshed with the tworacks at the same time. The package analyzer enables the operation efficiency of the blood transfusion compatibility test to be improved, and errors are not likely to happen.

Description

technical field [0001] The invention relates to blood transfusion compatibility test equipment, in particular to a package analyzer for blood transfusion compatibility detection. 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 samples 24 tim...
