MAGNETIC PARTICLE CHEMOLUMINESCENCE IMMUNOASSAY ANALYZER DARK BOX DETECTION SYSTEM

摘要

A magnetic particle chemoluminescence immunoassay analyzer dark box detection system, comprising: a base plate (6); and a dark detection box (1) arranged on the base plate (6). A dark chamber (10) having an opening at one side is provided in the dark detection box (1). An assay cup seat (2) is provided with a cup placement slot (20) for placing an assay cup, and is able to slide relative to the dark detection box (1) in order to open or close an inlet/outlet port (11). The assay cup seat (2) is provided with detection and cup placement positions within the sliding course thereof. When the assay cup seat (2) is positioned at the detection position, the cup placement slot (20) is located inside the dark chamber (10), and the inlet/outlet port (11) is closed. When the assay cup seat (2) is positioned at the cup placement position, the cup placement slot (20) is located outside of the dark chamber (10), and the inlet/outlet port (11) is opened. A driving mechanism (3) is used to drive the assay cup seat (2) to slide. A detection mechanism (4) is used to detect a luminescence amount of a liquid inside the assay cup in the dark chamber (10). A transporting apparatus is used to place the assay cup into the cup placement slot (20) or remove the assay cup from the cup placement slot (20). An open-door dark detection box structure that is independent from a grasper is used, effectively preventing interference between substrate injection and negative pressure suction from the grasper, thereby improving the reliability of grasper motions and detection results.
