[0045] See also Figures 1 to 8 As shown, the chemiluminescence detection device according to the present application is schematically shown, which is mainly used in a chemiluminescence immunoassay analyzer. After the excitation liquid is added to the reaction cup, the faint light generated by the chemiluminescence reaction in the reaction cup is detected.
[0046] A chemiluminescence detection device provided according to an embodiment of the present application includes: a detection box 310 , a movable cup holder 320 , an optical detector 330 and a driving member 340 .
[0047] The detection box 310 is provided with a cavity 311, one side of the cavity 311 is provided with an opening 312, a movable cup holder 320 is provided in the cavity 311, an optical detector 330 and a driving member 340 are provided on the detection box 310, a placement hole for placing a reaction cup is provided on the movable cup holder 320, and the placement hole is arranged in a vertical direction, a cover plate 321 matching with the opening 312 is provided on the movable cup holder 320, and the driving member 340 is connected to the movable cup holder 320, and the placement hole is not shown. The driving member 340 can drive the movable cup holder 320 to extend outward from the cavity 311 along the opening 312, and the driving member 340 can also drive the movable cup holder 320 to retract inward into the cavity 311 and the cover plate 321 covers the opening 312, and the optical detector 330 is used to detect the reaction cup on the movable cup holder 320 located in the cavity 311.
[0048] It should be noted that the movable cup holder 320 does not need to be fully extended out of the cavity 311 , as long as the placement hole on the movable cup holder 320 extends out of the detection box 310 to ensure that the reaction cup can be normally taken in and out.
[0049] The chemiluminescence detection device of the present application is installed at the corresponding position of the chemiluminescence immunoassay analyzer. When the excitation liquid is added to the reaction cup, the driving member 340 first drives the movable cup holder 320 to extend outward from the cavity 311 along the opening 312, and then the reaction cup to be detected is placed on the placement hole. Then the driving member 340 drives the movable cup holder 320 to retract inward into the cavity 311 and the cover plate 321 covers the opening 312, so that a light-tight environment is formed in the cavity 311. The optical detector 330 then detects the faint light generated by the chemiluminescence reaction in the reaction cup. When the detection is completed, the driving member 340 drives the movable cup holder 320 to extend outward from the cavity 311 along the opening 312, and the reaction cup is replaced for the next detection. This process is continuously repeated, thereby realizing accurate and efficient chemiluminescence detection.
[0050] Therefore, in the chemiluminescence detection device of the present application, the driving member 340 drives the movable cup holder 320 to extend outward or retract inward along the opening 312 of the cavity 311, and the cover plate 321 of the movable cup holder 320 can seal the opening 312, and a light-tight environment is formed in the cavity 311 of the detection box 310, so that the light-tightness is good, the detection accuracy is improved, and the structure is simple, the size is small, the operation is convenient and fast, and the efficiency is high, which is convenient for better application in chemiluminescence immunoassay analyzers.
[0051] In some embodiments, the optical detector 330 uses a photon counter installed outside the detection box 310. The photon counter is an extremely weak light pulse detection device based on the direct detection quantum limit theory. It uses the single photon detection technology of the photomultiplier tube (PMT). The photomultiplier tube is a vacuum electronic device that converts weak light signals into electrical signals. By identifying and measuring the number of photons per unit time, the electronic counter detects the power of discrete weak light pulse signals and realizes chemiluminescence detection. As a result, the detection accuracy is higher, more stable and reliable.
[0052] In some embodiments, the detection box 310 is provided with a second through hole 314 corresponding to the detection end of the optical detector, the second through hole 314 is connected to the cavity 311, and the movable cup holder 320 is provided with a first avoidance groove 323 corresponding to the detection end of the optical detector 330, the first avoidance groove 323 is located below the placement hole, and the lower end of the reaction cup passes through the placement hole and is located in the first avoidance groove 323. As a result, the structure is more compact, stable, smaller in size, and more convenient to operate.
[0053] In some embodiments, Figure 4As shown, the detection end of the optical detector 330 is provided with a focusing lens 331, and the focusing lens 331 corresponds to the second through hole 314 and the first avoidance groove 323. The focusing lens 331 can be located in the second through hole 314, and the front end of the focusing lens 331 can also pass through the second through hole 314 and extend into the cavity 311.
[0054] That is to say, when the driving member 340 drives the movable cup holder 320 to extend outward or retract inward along the opening 312 of the cavity 311, the first avoidance groove 323 can also avoid the front end of the focusing lens 331; when the movable cup holder 320 retracts inward into the cavity 311 and the cover plate 321 covers the opening 312, a light-tight environment is formed in the cavity 311. When the optical detector 330 detects the faint light generated by the chemiluminescent reaction in the reaction cup, the reaction fluorescence is focused and detected through the focusing lens 331, which can increase the area of light entering the detection sensor, thereby ensuring better detection, higher accuracy and higher efficiency.
[0055] In some embodiments, the driving member 340 is a motor installed on the outside of the detection box 310, such as a stepper motor, a servo motor, etc. The detection box 310 is provided with a first through hole 313 for the output shaft of the motor to pass through. The first through hole 313 is connected to the cavity 311, and the output shaft of the motor is connected to the transmission mechanism 350. The transmission mechanism 350 is connected to the movable cup holder 320. The transmission mechanism 350 is located in the cavity 311. The driving member 340 drives the movable cup holder 320 to reciprocate horizontally and linearly through the transmission mechanism 350.
[0056] When the reaction cup needs to be placed on the movable cup holder 320, the motor drives the movable cup holder 320 to extend outward from the cavity 311 along the opening 312 through the transmission mechanism 350. When chemical reflection detection is required, the motor drives the movable cup holder 320 to retract into the cavity 311 through the transmission mechanism 350 and the cover plate 321 covers the opening 312, so that a light-tight environment is formed in the cavity 311. In this way, the operation is more convenient, the movable cup holder 320 can be moved better, and the stability and reliability are higher.
[0057] Those skilled in the art will appreciate that the driving member 340 may also be a power element such as a cylinder, an electric cylinder, a linear module, etc., to drive the movable cup holder 320 to perform horizontal linear reciprocating motion.
[0058] In some embodiments, the transmission mechanism 350 includes: a meshing gear 351 and a rack 352. The gear 351 is arranged on the output shaft of the motor, and the rack 352 is installed on the movable cup holder 320 in the horizontal direction. The motor drives the gear 351 to rotate, and the gear 351 cooperates with the rack 352, so that the rack 352 and the movable cup holder 320 can reciprocate horizontally and linearly together. As a result, the movement is more stable and reliable.
[0059] In some embodiments, a guide mechanism 360 is provided in the cavity 311, the guide mechanism 360 cooperates with the movable cup holder 320, the extension direction of the guide mechanism 360 is consistent with that of the rack 352, the motor drives the gear 351 to rotate, the gear 351 cooperates with the rack 352, so that the rack 352 and the movable cup holder 320 can reciprocate horizontally and linearly along the guide mechanism 360. As a result, the movement is smoother, and the stability and reliability are higher.
[0060] In some embodiments, the guide mechanism 360 includes a guide rail 361 and a slider 362 that fits on and slides along the guide rail 361. The guide rail 361 is installed on the inner wall of the cavity 311. The slider 362 is connected to the movable cup holder 320. The gear 351 is located above the rack 352. The guide mechanism 360 is located above the gear 351. The movable cup holder 320 is provided with a first slot 324 that fits with the slider 362 and a second slot 325 that corresponds to the gear 351 and the rack 352. As a result, the structure is more compact, stable, smaller, more stable and reliable.
[0061] Those skilled in the art will appreciate that the transmission mechanism 350 may also be a synchronous belt mechanism or a transmission chain mechanism, and the guide mechanism 360 may also be a slide groove that matches the movable cup holder 320 .
[0062] In some embodiments, the cover plate 321 is provided with a sealing ring 326 corresponding to the opening 312. Therefore, when the cover plate 321 covers the opening 312, the sealing ring 326 is tightly pressed against the outer periphery of the opening 312, which has better sealing performance, can ensure a better light-tight environment, and has higher detection accuracy.
[0063] In some embodiments, the movable cup holder 320 is provided with a connecting portion 322 connected to the cover plate 321. The connecting portion 322 may be substantially flat, and the size of the connecting portion 322 is smaller than the size of the cover plate 321 and the size of the opening 312. Thus, the connection is more convenient.
[0064] In some embodiments, the detection box 310 is disposed on a bottom plate 380, and the bottom plate 380 is used to be installed and fixed at a corresponding position of the chemiluminescent immunoassay analyzer. The bottom plate 380 is provided with a mounting hole 381 and a second avoidance groove 382 corresponding to the cover plate 321. The number and arrangement of the mounting holes 381 are determined according to the specific conditions such as the size of the detection box 310. As a result, the operation is more convenient, the structure is more stable, and the second avoidance groove 382 is also convenient for avoiding the cover plate 321.
[0065] In some embodiments, a detection switch 371 for detecting the position of the movable cup holder 320 is provided on the detection box 310, and the detection switch 371 can be a photoelectric switch, a slot-type optical coupling sensor, a proximity switch or a forming switch, etc. Therefore, the moving position of the movable cup holder 320 can be more accurately controlled by the detection switch 371, which is safer and more reliable.
[0066] In some embodiments, the detection switch 371 is installed on the fixed plate 370, and a third groove body 315 matching the fixed plate 370 is provided on the outer side of the detection box 310. A third through hole 316 corresponding to the detection switch 371 is provided in the third groove body 315, and the third through hole 316 is connected to the cavity 311.
[0067] That is to say, the detection switch 371 detects the position of the movable cup holder 320 in the cavity 311, that is, detects the position of the movable cup holder 320 during chemiluminescence detection, thereby ensuring that the movable cup holder 320 moves to the detection position more accurately, with higher safety and reliability.
[0068] The fixing plate 370 is also provided with a wiring port 372, which is located outside the third slot 315, and is used to connect to other devices such as a power source and a control system, thereby making the operation more convenient.
[0069] In some embodiments, the driving member 340 and the optical detector 330 are located on the same side of the detection box 310, the fixing plate 370 is located on the side of the detection box 310 away from the driving member 340, and the cover plate 321 is arranged in the vertical direction. Figure 1 For reference, the driving member 340 and the optical detector 330 are located at the front side of the detection box 310, the fixing plate 370 is located at the rear side of the detection box 310, and the opening 312 of the cavity 311 is located at the right side of the detection box 310. Thus, the operation is more convenient.
