Description

Magnetic particle chemiluminescence immunity analyzer carrier anti-offset and ultrasonic anti-blocking device Technical Field The utility model relates to the technical field of chemical analysis instruments, in particular to an anti-offset and ultrasonic anti-blocking device for a carrier of a magnetic particle chemiluminescence immunoassay instrument. Background The Flash900 full-automatic chemiluminescence immunoassay analyzer is a highly-automatic detection device, and the main components of the full-automatic chemiluminescence immunoassay analyzer comprise a host part, a microcomputer processing system and other auxiliary components. The host part covers a material preparation module (a reaction cup bin, a sample bin, a reagent bin and the like), a liquid path module (a vacuum pump, a pipeline, a probe and the like), a temperature control module (an incubator, a reagent incubator and the like), a mechanical transmission module (a sensor, a transportation rail, a mechanical arm and the like), a light path detection module (a high-sensitivity sensor such as a photomultiplier) and a circuit control module (a power supply, an amplification processing system and a circuit control board). The microcomputer processing system is used as a command and control center of the instrument and has the functions of program control operation, automatic monitoring, instruction judgment, data processing, fault diagnosis and the like. In addition, sample handling systems (transfer chambers, main probe systems), laboratory operating systems (fluid systems including wash solutions, waste solutions, substrate pumps and valves, etc.), central supply and control systems (reactor tube support, reactor tube supply tanks, constant temperature zones and electro-optical reading tanks), peripheral devices (color monitors, printers, keyboards, barcode scanners, etc.), are included. The components work cooperatively, so that the instrument can efficiently and accurately finish the chemiluminescent immunoassay detection task. The chemiluminescent immunoassay analyzer under the specification and model has defects in the specific use process, and firstly, the connectivity between a carrier plate in a sample bin and a sample tube rack is insufficient. In practice, when a person places a sample rack on the carrier tray, the sample rack on the carrier tray is subsequently pushed into the sample bin by the provided push plate. Due to insufficient connectivity, the sample pipe rack may have an offset phenomenon in the pushing process, so that the sample pipe rack cannot accurately enter the sample bin, and the detection efficiency and accuracy are affected. The offset phenomenon not only increases the adjustment time of operators, but also can cause the damage of a sample rack or the leakage of sample liquid, thereby further affecting the reliability of a detection result; Secondly, the sample tube rack in the analyzer has the disadvantage in use that the upper end of the sample tube can completely enter the slot when the sample tube is placed in the slot of the rack. After the experiment is finished, the staff needs to dial the sample tube upwards through the breach of rack one side until sample tube upper end protrusion in the groove drill way, and then comes to take the sample tube, and this operation of taking has inconvenience, has influenced the use convenience of sample tube rack. In addition, the probe of the prior art has a sample liquid or a reagent liquid remaining therein after sucking and transferring the sample liquid or the reagent. When the sample liquid or the reagent liquid is sucked next time, the liquid adhered to the inner wall of the probe can cause the probe to suck the liquid unsmoothly, and even a blocking phenomenon occurs. The blockage not only affects the accurate suction and transfer of the sample liquid and the reagent, but also can cause cross contamination of the sample liquid or the reagent, and reduces the detection accuracy.
