step S503: moving the sample adding needle to a tray of the reagent sample assembly to absorb the diluent, adding the diluent to the reaction cup, and then cleaning the sample adding needle;
step S504: the blending component is used for blending the reaction cups;
step S505: the mechanical gripper takes the reaction cup out of the blending component and sends the reaction cup to an incubation disc for incubation;
step S506: after incubation is finished, the reaction cup is taken out from the incubation disc by the mechanical gripper and is sent to the blending assembly, and the sample adding needle absorbs part of the sample from the blending assembly reaction cup and moves away;
step S507: the mechanical gripper takes out the reaction cup at the blending component and sends the reaction cup to a cup losing position to discard the reaction cup;
step S508: a mechanical gripper takes a new reaction cup from the reaction cup tray and sends the new reaction cup to the blending component, and a sample adding needle flows the diluted sample sucked from the previous reaction cup into the new reaction cup;
step S509: the test is continued according to the one-step method A, the one-step method B and the two-step method.
Compared with the prior art, the small-sized full-automatic chemiluminescence analysis system provided by the invention realizes and supports various reaction methodologies by integrating all components for chemiluminescence analysis on the rack, and has the advantages of high automation degree, small volume, simple structure, low cost and complete functions.
While the foregoing is directed to embodiments of the present invention, it will be understood by those skilled in the art that various changes may be made without departing from the spirit and scope of the invention.
