The present embodiment provides a chemiluminescent immunoassay analyzer. Referring to fig. 1, the chemiluminescence immunoassay analyzer comprises a housing 5, wherein a window 51 is formed on the housing 5, and the window 51 is used for assembling and disassembling the microfluidic chip 6. Referring to fig. 2 and 3, the chemiluminescence immunoassay analyzer includes a chip tray 1 disposed in a housing 5, a reagent injection mechanism 2, a drive mechanism 3, and a fluorescence detection device 4.

The chip tray 1 is used for loading the microfluidic chip 6. The reagent injection mechanism 2 is used for injecting a reagent into a detection area of the microfluidic chip 6. The driving mechanism 3 is used for enabling the microfluidic chip 6 on the chip tray 1 to move relative to the reagent injection mechanism 2, and the driving mechanism 3 is connected with the chip tray 1 so as to drive the chip tray 1 to move. The fluorescence detection device 4 is used for detecting the fluorescence intensity of the sample in the microfluidic chip 6, and the fluorescence detection device 4 is provided with a detection port for injecting fluorescence. The chip tray 1 is provided with a reagent injection position (shown in fig. 4c and 4 d) and a detection position (shown in fig. 4 e), when the chip tray 1 is at the reagent injection position, the reagent injection mechanism 2 is inserted into the microfluidic chip 6, and as the chip tray 1 continues to move, the reagent injection mechanism 2 moves relative to the microfluidic chip 6 to push the reagent to inject the reagent into the detection area of the microfluidic chip 6; when the chip tray 1 is located at the detection position, the chip tray 1 is located below the fluorescence detection device 4, the detection area of the microfluidic chip 6 loaded on the chip tray 1 can be opposite to the detection port of the fluorescence detection device 4, and then the fluorescence in the detection area can enter the fluorescence detection device 4 through the detection port.
The chemiluminescence immunoassay analyzer is matched with the microfluidic chip 6 for use, and the embodiment also provides a chemiluminescence immunoassay system which comprises the chemiluminescence immunoassay analyzer and the microfluidic chip 6. As shown in fig. 4a, the microfluidic chip 6 has a detection area 61 and a reagent storage area, a micro-channel is provided between the detection area 61 and the reagent storage area, a plunger is provided in the reagent storage area, after the plunger is pushed by an external force, the reagent in the reagent storage area is extruded by the plunger and enters the detection area 61 through the micro-channel, so as to realize incubation, reaction and the like, and the detection area 61 is used for reaction and detection after reaction. Specifically, two reagent storage areas are separately arranged in the microfluidic chip 6, a first movable plunger 63 is arranged in the first reagent storage area, and a second movable plunger 64 is arranged in the second reagent storage area. In one specific application example, a phage buffer solution is pre-stored in the first reagent storage region, and a sunflower aldehyde solution is pre-stored in the second reagent storage region, and the chemiluminescence immunoassay analyzer can detect bacteria (such as mycobacterium tuberculosis) in a biological sample. The first reagent storage area and the second reagent storage area are both located on the rear side of the microfluidic chip 6. The detection zone 61 is located substantially in the middle of the microfluidic chip 6 and has a hole for transmitting fluorescence. The micro-fluidic chip 6 is also provided with a quality control port 62, the quality control port 62 is positioned at the rear of the detection area 61, the quality control port 62 can be used for pre-placing phage solution, and reaction liquid is added into the quality control port 62 when the micro-fluidic chip is used.
As shown in fig. 3, the chip tray 1 is slidably disposed on the guide rails. The guide rail mainly comprises a pair of linear guide rails 52 arranged in parallel, the linear guide rails 52 are fixedly arranged on the shell 5, and two sides of the chip tray 1 are respectively connected with the corresponding linear guide rails 52 in a sliding fit manner. The chip tray 1 is provided with a mounting groove 10 for the micro-fluidic chip 6 to be clamped in, and the shape of the mounting groove 10 in plan view is consistent with that of the micro-fluidic chip 6. The front side part of the chip tray 1 is provided with a front limiting block 11, the rear side part of the chip tray 1 is provided with a rear limiting block 12, and the height of the front limiting block 11 is smaller than that of the rear limiting block 12, so that the micro-fluidic chip 6 can conveniently enter and exit the mounting groove 10. The front limiting blocks 11 are two in number and arranged at intervals, so that hands and the like can clamp the microfluidic chip 6 to assemble and disassemble the microfluidic chip; the rear stoppers 12 are two in number and spaced apart to provide a space for allowing the reagent injection mechanism 2 to move in and out of the microfluidic chip 6 to push the plunger. Herein, the longitudinal direction of the linear guide 52 is defined as the front-rear direction, the side of the chip tray 1 farther from the reagent injection mechanism 2 is defined as the front side portion, and the side of the chip tray 1 closer to the reagent injection mechanism 2 is defined as the rear side portion.
As shown in fig. 2 and 3, the reagent injection mechanism 2 includes one or more push rods that can be inserted into the microfluidic chip 6. Further, after the push rod is inserted into the microfluidic chip 6, the push rod is matched with the plunger therein, and as the chip tray 1 drives the microfluidic chip 6 to move, the plunger is blocked by the push rod to extrude the reagent in front of the plunger into the detection area 61 of the microfluidic chip 6. The number of push rods corresponds to the number of plungers. Thus, the reagent injection mechanism 2 includes a first push rod 21 corresponding to the first plunger 63 and a second push rod 22 corresponding to the second plunger 64. As the microfluidic chip 6 moves backwards, the first plunger 63 abuts against the first push rod 21 to receive the resistance of the first push rod 21, and when the resistance is larger than the friction force received by the first plunger 63 in the microfluidic chip 6, the first plunger 63 moves forwards relative to the microfluidic chip 6 to squeeze the reagent in the first reagent storage region into the detection region 61; similarly, the second plunger 64 can squeeze the reagent in the second reagent storage region into the detection zone 61.
Further, the first push rod 21 and the second push rod 22 do not move synchronously, and when the first push rod 21 pushes the first plunger 63, the second push rod 22 does not contact the second plunger 64 yet; after the reagent in the first reagent storage region is squeezed into the detection region 61, a reaction is required for a certain period of time (e.g., 15min after the phage buffer solution is squeezed), and then the second push rod 22 squeezes the reagent in the second reagent storage region into the detection region 61, at which time the first push rod 21 can move backward along with the microfluidic chip 6 so that the second push rod 22 can contact the second plunger 64. Specifically, the first push rod 21 and the second push rod 22 are both disposed on the mounting plate 23, and the mounting plate 23 is fixedly disposed on the housing 5. Wherein the first push rod 21 is movably arranged on the mounting plate 23, and the second push rod 22 is fixedly arranged on the mounting plate 23. The mounting plate 23 is fixedly provided with a push rod seat 24, the first push rod 21 and the second push rod 22 are parallel to each other and extend along the front-back direction, the first push rod 21 can be movably arranged on the mounting plate 23 along the length direction (i.e. the front-back direction) thereof, one end part of the first push rod 21 is movably inserted into the push rod seat 24, and an elastic part 25 is arranged between one end part (i.e. the rear end part) of the first push rod 21 and the push rod seat 24. The elastic member 25 is specifically a compression spring which is pressed between one end of the first push rod 21 and the push rod holder 24. The length of the first push rod 21 which can be inserted into the microfluidic chip 6 is longer than that of the second push rod 22 which can be inserted into the microfluidic chip 6, so that the first push rod 21 contacts the first plunger 63 first, and the second push rod 22 contacts the second plunger 64 after the reagent in the first reagent storage region is squeezed in, and the reagent in the second reagent storage region is injected in. Accordingly, the chip tray 1 has a first reagent injection position corresponding to the first push rod 21 (as shown in FIG. 4 c) and a second reagent injection position corresponding to the second push rod 22 (as shown in FIG. 4 d), the second reagent injection position being located between the first reagent injection position and the detection position (as shown in FIG. 4 e).
As shown in fig. 2 and 3, the driving mechanism 3 includes a motor, and an output shaft of the motor is connected to the chip tray 1. Specifically, the motor is a linear motor 31, the linear motor 31 is mounted on the housing 5, and an output shaft of the linear motor 31 is connected to the chip tray 1 through a connecting member. As the linear motor 31 operates, the chip tray 1 moves in the front-rear direction therewith.
As shown in fig. 2, the fluorescence detection device 4 includes a photomultiplier tube 41 and a counter 42. A photomultiplier tube 41 (PMT for short) converts a fluorescence signal incident from the detection port into an electric signal, and a counting device 42 is electrically connected to the photomultiplier tube 41 to obtain the number of the target (e.g., Mycobacterium tuberculosis) to be detected based on the electric signal output from the photomultiplier tube 41. The detection port is specifically a detection port of the photomultiplier tube 41, and is used for providing fluorescence inside the photomultiplier tube 41. In this embodiment, the photomultiplier 41 is disposed above the chip tray 1, and the counter 42 is disposed beside the chip tray 1.
As shown in fig. 2 and 3, the chemiluminescence immunoassay analyzer further includes a control board 53, a power supply module 54, and a switch 55 for controlling the power supply module 54. The control board 53 is electrically connected to the linear motor 31 to send a control signal for controlling the start and stop of the linear motor 31 according to a preset detection program. The control board 53 is also electrically connected to the counting device 42 to obtain the detection information obtained by the counting device 42, and display, output, etc. The power supply module 54 is used for supplying power to the linear motor 31, the photomultiplier tube 41, the counting unit, the control board 53, and the like, and the power supply module 54 may be a power line used for being connected to an external power source such as commercial power, and may also be a battery (e.g., a rechargeable battery).
The detection method of the chemiluminescence immunoassay analyzer comprises the following steps:
1. as shown in fig. 4a, the chip tray 1 is located at the front side of the guide rail, and even part of the chip tray can be located outside the housing 5 through the window 51, and the microfluidic chip 6 is loaded on the chip tray 1;
2. when the linear motor 31 operates, the chip tray 1 carrying the microfluidic chip 6 moves backwards along the linear guide rail 52 until the quality control port 62 of the microfluidic chip 6 faces the detection port 411 of the photomultiplier 41, as shown in fig. 4 b; and in this process, the front part of the first push rod 21 is inserted into the microfluidic chip 6, but the first plunger 63 is not yet pushed;
3. the linear motor 31 continues to operate, the chip tray 1 carries the microfluidic chip 6 to continue moving backwards along the linear guide rail 52, and in the moving process of the microfluidic chip 6, the first plunger 63 abuts against the first push rod 21 to be blocked, so that the reagent (such as phage buffer) in the first reagent storage region is squeezed into the detection region 61, as shown in fig. 4 c; the linear motor 31 stops running, and the chip tray 1 keeps the first reagent injection position shown in fig. 4c for a period of time to perform reaction, incubation, etc., for example, 15min after extruding phage buffer;
4. after the incubation is completed, the linear motor 31 continues to operate, the chip tray 1 carrying the microfluidic chip 6 further moves backwards along the linear guide rail 52, in the process that the microfluidic chip 6 continues to move, the second push rod 22 is inserted into the microfluidic chip 6 and abuts against the second plunger 64, the second plunger 64 is subjected to the resistance of the second push rod 22 to squeeze the reagent (such as the sunflower aldehyde solution) in the second reagent storage region into the detection region 61, and the second reagent injection position is shown in fig. 4 d; in this process, the pushing force of the first plunger 63 exerted on the first push rod 21 increases and pushes the first push rod 21 to move backward together, and the elastic member 25 is compressively deformed;
5. the linear motor 31 runs in reverse direction, and the chip tray 1 with the microfluidic chip 6 moves forward until the detection area 61 of the microfluidic chip 6 faces the detection port 411 of the photomultiplier 41, as shown in fig. 4 e;
6. after the detection is finished, the linear motor 31 continues to move reversely, the chip tray 1 carrying the microfluidic chip 6 exits the window 51, and the microfluidic chip 6 is dismounted from the chip tray 1.
During the reverse operation of the linear motor 31, the pushing force exerted by the first plunger 63 on the first push rod 21 is reduced until the pushing force disappears, and the restoring force of the elastic element 25 drives the first push rod 21 to restore for the next detection.
