As shown in fig. 1 to 8, the novel fluorescence immunoassay analyzer of the present invention includes a housing 1, the housing 1 has a hollow cavity, and the analyzer further includes a detection module 2 disposed in the hollow cavity of the housing 1.

The housing 1 includes an upper housing 11 and a lower housing 12 located below the upper housing 11, and a hollow cavity is formed between the upper housing 11 and the lower housing 12. Preferably, the upper housing 11 and the lower housing 12 are detachably connected, which facilitates installation, maintenance and replacement of the test module 2 and other components in the housing 1.

The detection module 2 is disposed on the lower case 12. The detection module 2 comprises a base 21, the lower part of the base 21 is fixedly arranged on the lower shell 12, and the base 21 is provided with a placement part 211 for placing the tested reagent strip 100.

The detection module 2 further comprises a sensor 22, the sensor 22 is slidably disposed on the base 21 and located above the tested agent strip 100, and the sensor 22 is used for detecting the tested agent in the tested agent strip 100.

The sensor 22 has an initial position and a detection position which slide relative to the base 21, and a test strip 100 is provided with a reagent tank 101 for placing a test reagent. When the analyzer is not in operation, the sensor 22 is in the initial position, in which the position of the sensor 22 is offset from the position of the reagent tank 101. When the analyzer is operated to perform detection, the sensor 22 slides to the detection position with respect to the base 1, as shown in fig. 7, and the position of the sensor 22 faces the reagent tank 101, so that the reagent to be tested in the reagent tank 101 can be detected by the sensor 22.

The detection module 2 further comprises a driving mechanism for driving the sensor 22 to slide relative to the base 21. As shown in fig. 4 to 8, the driving mechanism includes a motor 23, a gear 24, a rack 25, and a bracket 26. The motor 23 is provided on the base 21. The gear 24 is fixedly arranged on a motor shaft of the motor 23, the rack 25 is slidably arranged on the base 21, and the bracket 26 is fixedly arranged on the rack 25. The gear 24 is engaged with a rack 25, and the sensor 22 is fixedly disposed on a bracket 26.

When the motor 23 is started, the gear 24 is driven to rotate, the rack 25 is driven to slide relative to the base 21 through the meshing of the gear 24 and the rack 25, and when the rack 25 slides, the bracket 26 is driven to synchronously slide, so that the sensor 22 can slide relative to the base 21. The sensor 22 may be moved from an initial position to a detection position to detect the test agent. After the detection is completed, the sensor 22 may also return to the initial position from the detection position.

The detection module 2 further comprises a limiting component, and the limiting component is used for limiting the sliding position of the sensor 22 so that the sensor 22 can be located at the initial position and the detection position respectively.

When the sensor 22 is at the initial position, the stopper rod 272 faces the stopper 271. When the motor 23 starts to rotate forward, the driving rack 25 moves relative to the base 21, and drives the limiting rod 272 to move relative to the base 21 synchronously, and the limiting rod 272 gradually deviates from the limiter 271. When the limit rod 272 deviates from the limit device 271 by a set distance, the sensor 22 moves to the detection position, the motor 23 stops working, and the sensor 22 detects the tested reagent. After the sensor 22 finishes detecting, the motor 23 is started to rotate reversely, the driving rack 25 drives the limiting rod 272 to slide reversely relative to the base 21 until the limiting rod 272 faces the limiter 271, and the sensor 22 returns to the initial position.
