Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] A POCT chemiluminescence immunoassay analyzer, as shown in Figures 1-8 The installation box 1 is provided with the analyzer 2 for detecting the reagent card 5, the incubation assembly 8 is fixedly connected in the installation box 1, the tray 3 and the mixing assembly 81 are fixedly connected to the top of the incubation assembly 8, the rotating frame 4 is rotatably connected to the top of the incubation assembly 8, twelve limit blocks 41 for placing the reagent card 5 are fixedly connected to the rotating frame 4 at intervals in the circumferential direction, the guide frame 6 is fixedly connected to the outer wall of the installation box 1 and penetrates through the outer wall of the installation box 1, the feeding frame 7 is slidably connected in the guide frame 6, the rotating disc 9 is rotatably connected in the installation box 1, six drip assemblies 10 are fixedly connected to the outer wall of the rotating disc 9 at intervals in the circumferential direction, the six drip assemblies 10 are respectively used for dripping different types of chemiluminescent agents, the reagent storage frame 11 for storing different chemiluminescent agents is fixedly connected to the bottom of the rotating disc 9, when the chemiluminescent agent in the drip assembly 10 is insufficient, the reagent storage frame 11 can be used for supplementing, the fixed frame 12 is fixedly connected to the top of each limit block 41, the pressing block 13 is slidably connected to the bottom of each fixed frame 12, the side of the pressing block 13 away from the center of the incubation assembly 8 is a slope, and the return spring 14 is fixedly connected between the pressing block 13 and the fixed frame 12.

[0023] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, it also includes connecting plates 82, waste card collection frame 15, guide frame 16 and hinged plate 17, the side of tray 3 away from rotating disc 9 is provided with a notch, two connecting plates 82 are fixedly connected to the outer wall of incubation assembly 8, the two connecting plates 82 are located on the front and back sides of the notch, guide frame 16 is fixedly connected between tray 3 and connecting plate 82, hinged plate 17 is hingedly connected between the two connecting plates 82, torsion spring is fixedly connected between hinged plate 17 and connecting plate 82, waste card collection frame 15 is slidingly connected in incubation assembly 8, and waste card collection frame 15 penetrates installation box 1.

[0024] In use of the analyzer, feeding frame 7 is first pulled out along guide frame 6, reagent card 5 with sample drops is placed on feeding frame 7, and feeding frame 7 is then pushed back into installation box 1 along guide frame 6, so that reagent card 5 enters into limiting block 41, the operation is simple, reagent card 5 does not need to be inserted into the analyzer by hand, cross infection between hands and reagent card 5 is avoided, and the safety of the analyzer is improved. In this process, reagent card 5 extrudes the inclined surface part of pressing block 13, so that pressing block 13 moves upward to compress reset spring 14, under the elastic force of reset spring 14, reagent card 5 can be fixed between pressing block 13 and tray 3. Rotating frame 4 is controlled to rotate by analyzer 2, so that limiting block 41 close to guide frame 6 rotates to be close to rotating disc 9. When reagent card 5 is located directly below dripping assembly 10, rotating disc 9 is controlled to rotate by analyzer 2, so that corresponding dripping assembly 10 rotates to be directly below reagent card 5. Chemical luminescent agent is dropped on reagent card 5 by corresponding dripping assembly 10. Rotating frame 4 is controlled to rotate clockwise, so that reagent card 5 on which chemical luminescent agent is dropped rotates away from dripping assembly 10. Reagent card 5 is incubated by incubation assembly 8 and mixing assembly 81. After a period of time, reagent card 5 is detected and analyzed by analyzer 2, and the analysis result is displayed on analyzer 2. Rotating frame 4 is continuously controlled to rotate clockwise. When reagent card 5 is located at the notch, reagent card 5 is separated from limiting block 41 and pressing block 13 under the action of gravity. Reagent card 5 falls on hinged plate 17 from the notch along guide frame 16. Guide frame 16 can prevent reagent card 5 from being stuck on incubation assembly 8 when falling, so as to ensure that reagent card 5 can normally fall into waste card collection frame 15. Hinged plate 17 rotates under the extrusion action of reagent card 5, and torsion spring is compressed. Reagent card 5 falls into waste card collection frame 15. Torsion spring restores to its original state to make hinged plate 17 reverse and reset, so that the collection of reagent card 5 is completed. Hinged plate 17 can isolate waste card collection frame 15 from limiting block 41, so as to prevent cross infection between waste cards and reagent card 5, and further improve the safety of the analyzer. Finally, waste card collection frame 15 is pulled out from incubation assembly 8, waste cards in waste card collection frame 15 are cleaned, and empty waste card collection frame 15 is moved to reset into incubation assembly 8.
