[0002] Chemiluminescent immunoassay is an instrument that uses chemiluminescent immunoassay technology and reaction principles to qualitatively or quantitatively detect analytes in human serum, plasma or other body fluid samples, and is used to assist in the diagnosis of related diseases. Chemiluminescent immunoassay consists of two parts, namely the immune response system and the chemiluminescent analysis system. The immune response system marks the marker substance on the antigen or antibody, and after a specific immune reaction, an antigen-antibody complex is formed, and then the marker is detected to determine the analyte. The chemiluminescent analysis system uses the catalysis of the chemiluminescent substance or the oxidation of the oxidant to form an excited intermediate. When this excited intermediate returns to the stable ground state, it will emit photons at the same time, which are detected by the optical signal detector and converted into the concentration of the analyte by the computer data processing system.

[0041] Reference Figure 1 , Figure 2 and Figure 3 A chemiluminescent immunoassay analyzer includes a frame 100 and a manipulator device 200, an incubation device 300, a cleaning device 400, and a reading device 500 respectively arranged on the frame 100; the manipulator device 200 is used to grab and transport a reaction cup 1 and add a detection material to the reaction cup 1; the incubation device 300 can generate heat to incubate the object to be tested in the reaction cup 1, and can shake the reaction cup 1; the cleaning device 400 can separate the immune complex and waste liquid in the reaction cup 1 and can clean the immune complex in the reaction cup 1; the reading device 500 includes a first shell 510, a second shell 520, a photon counter 530, a first platform 540 and a first driving mechanism 550, the second shell 520 is movably inserted in the first shell 510, and the second shell 520 is respectively provided with There is a first cup placing hole 521 for placing a reaction cup 1 and a photometric hole 522 connected to the lower end of the first cup placing hole 521. A photometric connecting hole 511 is provided on the first shell 510. The photon counter 530 is connected to the photometric connecting hole 511. The first driving mechanism 550 is arranged on the frame 100. The first driving mechanism 550 is drivingly connected to the first shell 510 and / or the first platform 540. The first platform 540 can move relative to the second shell 520 and can cover the upper end of the second shell 520. The second shell 520 can move up and down relative to the first shell 510. The photometric hole 522 and the photometric connecting hole 511 can be connected. The photon counter 530 can detect the luminescence of the reaction cup 1 in the photometric hole 522 through the photometric connecting hole 511. The second shell 520 can cover the photometric connecting hole 511.
[0042] When performing detection and analysis, the robot device 200 adds the test object and reagent to the reaction cup 1, and then transports it to the incubation device 300 for incubation and shaking, so that it undergoes a specific immune reaction to produce immune complexes. The robot device 200 transports the reaction cup 1 mixed with the immune complex and waste liquid to the cleaning device 400, and the cleaning device 400 separates the immune complex and waste liquid in the reaction cup 1 and cleans the immune complex. Then the robot device 200 transports the reaction cup 1 to the reading device 500 and places it in the first cup placement hole 521. Before reading, add luminescent liquid to the reaction cup 1.

[0050] In some embodiments, the cleaning device 400 includes a main frame 410, a conveying mechanism 420, a cleaning needle mechanism 430 and a magnet mechanism 440; the main frame 410 is provided with a liquid aspiration station and a liquid injection station; the conveying mechanism 420 is arranged on the main frame 410, and the conveying mechanism 420 includes a turntable 421 and a second driving assembly 422 capable of driving the turntable 421 to rotate, and the turntable 421 is provided with a third cup placement hole 423 for placing the reaction cup 1, and the conveying mechanism 420 can transport the reaction cup 1 placed in the third cup placement hole 423 to different stations, and the turntable 421 can reciprocate. Rotation; the cleaning needle mechanism 430 is arranged on the main frame 410 and corresponds to the liquid aspiration station and the liquid injection station. The cleaning needle mechanism 430 can absorb waste liquid from the reaction cup 1 and can inject cleaning liquid into the reaction cup 1; the magnet mechanism 440 is arranged on the main frame 410 and distributed on at least one side of the running path of the reaction cup 1 on the turntable 421. The magnet mechanism 440 includes at least one active magnet 441a component 441 corresponding to the liquid aspiration station. The active magnet 441a component 441 can absorb the immune complex in the reaction cup 1 and can drive the immune complex to move upward. Fig. 9 and Fig.10 As shown, when the immune complex is washed and separated, the turntable 421 rotates to transport the reaction cup 1 to the liquid aspiration station, the active magnet 441a component 441 adsorbs the immune complex in the reaction cup 1 to the bottom of the cup wall and drives it to move upward, so that it is at a preset height from the bottom of the cup, and the cleaning needle mechanism 430 is activated to absorb the waste liquid from the reaction cup 1 at this station.

Since the cup is filled with cleaning liquid, the immune complex on the cup wall is shaken back and forth and dispersed under the reciprocating rotation of the turntable 421 and the action of gravity, which facilitates the immune complex and the injected cleaning liquid to be fully mixed for cleaning, so that the immune complex in the reaction cup 1 obtains a better cleaning effect and achieves a better washing and separation effect.

Fig. 9 and Fig.10 As shown, the active magnet 441a adsorbs the immune complex in the reaction cup 1, and the magnet driver 441b drives the active magnet 441a to move, driving the immune complex adsorbed on the cup wall to move. It has a simple structure and a small volume, and can better achieve the purpose of adsorbing the immune complex in the reaction cup 1 and driving it to move, which can improve the reliability of the present invention. In practical application, the magnet driver 441b can be a linear motor, or a screw drive mechanism or a gear rack drive mechanism, and in addition to the active magnet 441a component 441, the main frame 410 can also be provided with fixed magnets at different liquid aspiration stations to be used in conjunction with the active magnet 441a component 441, thereby reducing the production cost of the present invention.
