The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0051] like Figure 1 and Figure 2 As shown, a rapid detection device 100 based on photoinduced chemiluminescence according to an embodiment includes: a frame module 10, a bin exit module 20, a mixing module 30, an incubation module 40, a detection module 50 and a gripper module 60. The frame module 10 is formed as a cubic frame structure as a whole, and has an installation cavity inside, which can be used to accommodate the bin exit module 20, the mixing module 30, the incubation module 40, the detection module 50 and the gripper module 60.

[0052] Specifically in this embodiment, Figure 1 From the perspective of , the gripper module 60 is arranged on the rear side of the frame module 10, the incubation module 40 and the warehouse exit module 20 are arranged on the front side of the frame module 10, the detection module 50 and the mixing module 30 are arranged in the middle position of the frame module 10, and are located between the gripper module 60 and the incubation module 40 and the warehouse exit module 20.

[0053] The warehouse outlet module 20 is arranged on the frame module 10 and corresponds to the material outlet; the mixing module 30 is arranged on the frame module 10; the incubation module 40 is arranged on the frame module 10 and arranged on one side of the mixing module 30; the detection module 50 is arranged on the frame module 10 and arranged on one side of the incubation module 40; the gripper module 60 is arranged on the frame module 10, and the moving range of the gripper module 60 covers the warehouse outlet module 20, the mixing module 30, the incubation module 40 and the detection module 50.

[0054] The implementation of the embodiments of the present invention will have the following beneficial effects: in the photoinduced chemiluminescence-based rapid detection device 100 of the present solution, by integrating the warehouse module 20, the mixing module 30, the incubation module 40, the detection module 50 and the gripper module 60 in the frame module 10, the layout of each functional module is compact, so that the entire detection device is small in size and light in weight, occupies a small installation space, and has a wider range of application scenarios. During the detection operation, each functional module is controlled by a preset program and can automatically cooperate. Specifically, the test kit 200 containing the reagent and sample freeze-dried into microspheres is loaded into the mixing module 30, and the reagent and sample are fully mixed by the mixing module 30, and then the gripper module 60 transfers the test kit 200 to the incubation module 40, which heats the test kit 200 and maintains it at a set temperature. Then, the gripper module 60 transfers the test kit 200 with a suitable temperature from the incubation module 40 to the detection module 50. The detection module 50 detects the test kit 200 and reads the test result. Finally, the gripper module 60 transfers the test kit 200 that has completed the test to the exit module 20, which sends the test device out of the exit module 20. In this way, the entire automatic detection operation can be completed. Since the liquid circuit structure is not involved, there is no need to perform liquid circuit structure maintenance and waste liquid treatment, which makes the operation convenient and simple, the detection cost is low, and no human intervention is required, saving time and effort.

[0055] like Figures 3 to 5 As shown, in one embodiment, the detection module 50 includes a detection base 51, a detection darkroom assembly 52 and a detection PMT assembly 53. The detection darkroom assembly 52 and the detection PMT assembly 53 are respectively arranged on the detection base 51, and the detection PMT assembly 53 is used to perform a detection operation on the reagent kit 200 in the detection darkroom assembly 52. ​​The detection base 51 is used to assemble the detection darkroom assembly 52 and the detection PMT assembly 53 on the frame module 10. After the reagent kit 200 to be detected is placed in the detection darkroom assembly 52, the detection PMT assembly 53 can perform a detection operation on the reagent kit 200.

[0056] The detection method is specifically as follows: In one embodiment, the detection darkroom assembly 52 includes a first photoelectric switch 521, a receiving light filter 522, a dichroic mirror 523, a detection cover 524, a guide column 525, a first rack 526, a rack bracket, a first photoelectric switch baffle 527, a first motor 528, a detection door motor seat 529, a first gear 529a, an excitation light source 529b, an excitation light filter 529c, and an excitation light seat 529d.

[0057] The first photoelectric switch 521, the receiving light filter 522 and the dichroic mirror 523 are respectively fixed on the detection base 51, and the detection cover 524 is connected to the detection base 51 for reciprocating movement through the guide column 525 to open or close the reagent tank of the detection base 51. The first rack 526 is set on the detection cover 524 through the rack bracket, the first photoelectric switch baffle 527 is set on the first rack 526, the first motor 528 is set on the detection door motor seat 529 and connected to the first gear 529a, the excitation light source 529b and the excitation light filter 529c are fixed on the excitation light seat 529d, and the excitation light seat 529d is fixed to the detection base 51.

[0058] After the reagent box 200 is placed in the reagent tank, the first motor 528 drives the first gear 529a and the first rack 526 to move, thereby driving the detection cover 524 to close the reagent tank, so that the reagent tank forms a dark room, avoiding the ambient light of the detection room from entering the reagent tank and causing interference, affecting the detection accuracy; through the first photoelectric switch 521 and the first photoelectric switch baffle 527, the blocking trigger can indicate that the detection cover 524 has completely covered the notch of the reagent tank; then, the excitation light source 529b emits excitation light, which is then irradiated to the corresponding detection area of ​​the reagent box 200 through the dichroic mirror 523 to generate corresponding receiving light, and the receiving light is reflected by the dichroic mirror 523 and the excitation light filter 529c, and then reaches the detection PMT component 53 through the receiving light filter 522 for data acquisition.

[0059] like Figure 5 As shown, in addition, in one embodiment, the detection PMT assembly 53 includes a darkroom upper plate 531, a darkroom shutter 532, a shutter crank 533, a rotary solenoid valve 534 and a photon counter 535. The photon counter 535 and the rotary solenoid valve 534 are respectively fixed on the darkroom upper plate 531. The darkroom shutter 532 is connected to the rotary solenoid valve 534 through the shutter crank 533 and a cylindrical pin. The photon counter 535 is arranged corresponding to the receiving light filter 522. During detection, the movement of the rotary solenoid valve 534 can drive the darkroom shutter 532 to open and close, thereby realizing the opening or closing of the detection shutter; when the detection shutter is opened, the photon counter 535 can receive the excitation light transmitted from the receiving light filter 522, thereby realizing the collection of corresponding optical data.

[0060] It should be noted that PMT, the abbreviation of "photomultiplier tube", is a widely used photoelectric conversion device. Its function is to convert and amplify the scintillation light generated by the crystal after being irradiated by gamma rays into electrical signals in proportion, with an amplification factor of up to 10 6 -10 9, so even very weak light can be measured. It is mainly composed of a photocathode, an electron focusing system, a multi-stage dynode and an anode. The entire system is enclosed in a vacuum glass shell. The photocathode is made by spraying some photosensitive materials on the inner side of the tube end window. The function of the photocathode is to convert the photons emitted by the scintillator into low-energy photoelectrons through the photoelectric effect. The dynode is made by vaporizing the photosensitive material on the sickle. There are multiple multiplication stages on the dynode. Each multiplication stage is applied with a voltage that increases in sequence. The electrons emitted by the photocathode are focused and accelerated by the electron focusing system and reach the first dynode. More electrons are generated through the second electron emission, and then multiplied step by step to reach enough electrons. The requirement for the dynode is that the secondary emission coefficient should be large and the multiplied secondary electrons should be effectively sent to the next stage. The anode is usually made of nickel, molybdenum and other materials. Its function is to collect the multiplied electrons and form an electrical pulse signal through the output circuit. This signal is then recorded and analyzed by electronic instruments.

[0061] like Figure 6 and Figure 7 As shown, in one embodiment, the incubation module 40 includes a reaction disk 41, a heating film 42, a temperature sensor 43, an over-temperature protection switch 44, an incubation disk support 45 and thermal insulation cotton 46.

[0062] The reaction disk 41 is a plate structure, which is used to load the reagent kit 200 and heat the reagent kit 200 by heat conduction. Since a plurality of grooves arranged in an array are provided, the reaction disk 41 can accommodate a plurality of reagent kits 200 at the same time, thereby improving the heating efficiency and saving the waiting time for heating to the required temperature; the heating film 42 is used to generate heat to heat the reaction disk 41; the temperature sensor 43 is used to collect the real-time temperature of the reaction disk 41, which is convenient for temperature control; the over-temperature protection switch 44 is used to protect the temperature control reaction of the reaction disk 41 from excessive temperature caused by hardware failure; the incubation disk support 45 is used to fix the incubation module 40 to the instrument bottom plate 11; the heat preservation cotton 46 is used to maintain the temperature of the incubation module 40 and reduce the heat dissipation efficiency.

[0064] During the detection, the reagent kit 200 is placed in the mixing holder 32, and then the vibration motor 33 is started. The vibration motor 33 applies vibration to the mixing holder 32, so that the reagents and samples in the reagent kit 200 can be mixed more fully and evenly, thereby helping to improve the accuracy of subsequent detection results.

[0065] like Fig.10 and Fig.11 As shown, in one embodiment, the gripper module 60 includes an X-axis driving module 61, a Y-axis driving module 62, a Z-axis driving module 63 and a gripper 64, the X-axis driving module 61 is connected to the Y-axis driving module 62, the Y-axis driving module 62 is connected to the Z-axis driving module 63, and the gripper 64 is arranged on the Z-axis driving module 63. During the detection operation, the X-axis driving module 61, the Y-axis driving module 62 and the Z-axis driving module 63 respectively output the moving force along the X-axis direction, the Y-axis direction and the Z-axis direction, so that the gripper 64 can be driven to move flexibly in any direction in the installation cavity of the frame module 10, so as to realize the flexible transfer of the reagent kit 200 between different functional modules, and ensure that the detection process is automatically and orderly completed.

[0066] Specifically, the X-axis drive module consists of an X-axis support arm, a linear guide and a stepper motor; the linear guide is fixed on the X-axis support arm to support the forward and backward movement of the Y-axis drive module; the photoelectric switch is fixed on the X-axis support arm and is used for hardware limit of the stepper motor; the synchronous wheel is fixed on the stepper motor; the idler wheel is fixed on the X-axis support arm through the X-axis idler wheel support shaft; the stepper motor drives the X-axis synchronous belt through the synchronous wheel to drive the idler wheel to move.
