Embodiment 1

[0050] see Figure 3 to Figure 12 The fluorescence immunoassay analyzer 1 of the present invention includes a bracket 10 and a reagent card insertion slot seat 2 installed on the bracket 10 , an information reading head 11 , a linear displacement output device 3 and a reagent card insertion guide and anti-extraction mechanism 4 . The reagent card insertion slot seat 2 is located on the lower side of the information reading head 11 . Wherein, the bracket 10 includes a bottom mounting plate 100 and a vertical mounting plate 101 connected into an integral structure, and the two are arranged in an L-shaped structure in cross section; the information reading head 11 is fixed on the vertical mounting plate 101 through the connecting frame 102 , the reagent card insertion slot 2 is installed on the bracket 10 in a reciprocating and slidable manner along the X-axis through the guide rail 51 and the guide rail 52 .

[0051] see Figure 18 , the reagent card insertion slot seat 2 incl...

Embodiment 2

[0065] As a description of Embodiment 2 of the present invention, only the differences from Embodiment 1 above will be described below.

[0066] see Figure 13 and Figure 14 , in the above-mentioned embodiment 1, during the unlocking process, it is necessary to manually toggle the plectrum to unlock, and usually two hands are required to perform the card pulling operation; and in this embodiment, the electromagnet 91 is arranged on the bottom mounting plate 100 to use The armature fixed on the unlocking mechanism 41 is magnetically attracted to complete the unlocking action, so that the reagent card 01 can be pulled out with one hand.

Embodiment 3

[0068] As an explanation of Embodiment 3 of the present invention, only the differences from Embodiment 1 above will be described below.

[0069] see Figure 15 to Figure 17 , in this embodiment, the guide roller 40 includes a support mandrel 42 rotatably installed on the roller mount 83, and an elastic roller 43 fixedly sleeved outside the support mandrel 42; in this embodiment, The supporting mandrel 42 is rotatably mounted on the bottom mounting plate 100 by rotating the supporting groove seat 85 and the rotating supporting groove seat 86; , its pawl 82 is fixed on the first roller mount 83; in the present embodiment, the ratchet 81 is fixed on the end of the supporting mandrel 42; the unlocking mechanism 41 is used to decouple the pawl 82 from the ratchet 81, in In this embodiment, the ratchet 82 is a reed with one end fixed on the first roller mounting seat 83; the unlocking mechanism 41 is an electromagnet, which is used to magnetically attract the free end of the reed ...

Abstract

The invention relates to a fluorescence immunoassay analyzer and a reagent card inserting, guiding and anti-pulling mechanism, and belongs to the field of immunoassay instruments. The fluorescence immunoassay analyzer comprises a support, and a reagent card inserting groove seat, an information reading head, a linear displacement output device and a reagent card inserting guide anti-pulling mechanism which are arranged on the support; the reagent card inserting, guiding and anti-pulling mechanism is arranged beside the inlet where the reagent card is inserted into the containing groove and comprises a roller mounting base, a guiding roller, a one-way rotation locking mechanism and an unlocking mechanism; the guide roller is rotatably mounted on the roller mounting seat and is at least usedfor providing guidance for the inserting action of the reagent card; the one-way rotation locking mechanism is used for releasably locking one-way rotation of the guide roller towards the reverse direction of the plug-in card; and the unlocking mechanism is used for controlling the working state of the one-way rotating locking mechanism so as to release the steering locking state of the guide roller. Based on the additionally-arranged reagent card inserting guiding anti-pulling mechanism, the risk can be effectively reduced, and the fluorescence immunoassay analyzer can be widely applied to the rapid detection of new coronaviruses and the like.

Description

technical field [0001] The invention relates to the field of in vitro diagnostic testing instruments, in particular to a fluorescent immunoassay analyzer and a reagent card inserting guide and anti-extraction mechanism that can be used to construct the fluorescent immunoassay analyzer. Background technique [0002] The immunochromatography detection technology in the field of in vitro diagnostic testing is a technology based on chromatography and antigen-antibody specific immune response; at present, the main immunochromatography technologies include fluorescence immunochromatography and colloidal gold chromatography, for example in the public Patent No. CN1645146A discloses an immunochromatographic method based on fluorescent substances as markers; because the rapid detection technology of immunochromatography has the advantage of shorter detection time, the detection and analysis results can even be obtained in half an hour, while It can be used as a real-time detection te...
