Description

Technical Field

[0001] This utility model relates to the field of chuck tray displacement technology, specifically a chuck tray displacement mechanism for an analyzer. Background Technology

[0002] Rapid immunochromatographic detection technology is based on chromatography and antigen-antibody specific immune reactions. Currently, there are two main types of immunochromatographic techniques: fluorescence immunochromatography and colloidal gold chromatography. Rapid immunochromatographic detection technology can be widely used for on-site quantitative detection and represents an important direction for the future development of point-of-care testing technology.

[0003] A two-in-one immunochromatographic analyzer, disclosed in publication number CN206756843U, includes a housing. A test strip slot is located on one side of the housing, and a test strip base is positioned facing the slot. A slide is located at the bottom inner side of the housing, and the test strip base is mounted on the slide via a transmission mechanism. An optical detection module is fixedly mounted on the slide, parallel to the test strip base. A detection mechanism is located between the test strip base and the optical detection module, connected to a controller. The controller is connected to the transmission mechanism and the optical detection module. By integrating different optical detection modules, the detector intelligently identifies colloidal gold test strips or fluorescent test strips. The overall structure is compact and feature-rich. When there are multiple quantitative detection needs on-site, it can serve two purposes in one machine, occupying little space and being easy to operate, thus meeting the needs of multifunctional immunochromatographic analysis.

[0004] While existing technologies can achieve reciprocating movement of test strips, they cannot effectively position and fix the test strips. Therefore, this application proposes a cassette tray shifting mechanism for an analyzer. Utility Model Content
