Description

Technical Field

[0001] The utility model relates to the technical field of detection instruments, and in particular to a pretreatment incubation fluorometer. Background Art

[0002] A fluorometer is an instrument for qualitative and quantitative analysis. Through the detection of the fluorometer, information such as the excitation spectrum, emission spectrum, quantum yield, fluorescence intensity, fluorescence lifetime, Stokes shift, fluorescence polarization and depolarization characteristics, and fluorescence quenching of substances can be obtained. The incubation fluorometer is mainly used for fluorescence detection after the incubation of various enzyme-linked immunosorbent assay kits and enzyme-catalyzed chemiluminescence immunoassays in medical institution laboratories. Incubation can accelerate and make the biological reaction or chemical reaction more sufficient, and reduce the within-batch difference of the reaction within a batch through incubation, making the reaction linear more stable, greatly shortening the time for experimental operation and detection, improving the efficiency of staff, and playing a wide role in the application fields of medicine and biology.

[0003] The existing Chinese patent with the name of a microsphere fluorometer and the patent number of CN214622323U includes a device main body. The device main body includes a fluorometer main body. A control panel is installed at the top end of the fluorometer main body. A hinge is installed at the top end of the fluorometer main body on one side of the control panel. A closing plate is installed on one side of the hinge. A fixing spring is installed on the side of the closing plate away from the hinge. The other end of the fixing spring is installed with a fixing block. A fixing groove is opened on the side of the fluorometer main body close to the fixing block, and the fixing block extends into the fixing groove. An empty groove is opened inside the fluorometer main body at the bottom end of the closing plate. Telescopic rods are installed on both sides of the inner wall of the empty groove. The other ends of the two telescopic rods are installed with a glass placement plate. A sleeve spring is sleeved on the outer surface of the telescopic rod. Cleaning mechanisms are installed on both sides of the control panel. Through the elastic force of the winding rod, the movable moving plate moves towards the direction close to the glass placement plate, so that the movable fixing plate can fix the test strip placed by the staff, thus facilitating the subsequent test strip detection.

[0004] Although the existing fluorometer will not cause the movement of the test strip due to the closing of the cabin door, which affects the detection result, the existing fluorometer lacks an incubation function, cannot accelerate the biological reaction or chemical reaction, cannot make the reaction more stable and sufficient, nor can it shorten the time for experimental operation and detection, and the work efficiency is not high.

[0030] Embodiment:

The detection head 4 is located on the side of the detection cover away from the test paper carrier 5. A distance sensor 8 is fixedly connected to the detection head 4. A sample placement frame 9, a side shift motor 91, a side shift synchronous belt 92, a synchronous transmission assembly and a tension adjustment assembly for adjusting the tension of the side shift synchronous belt 92 are also provided in the shell 1. The side shift motor 91 is fixedly arranged in the shell 1. The synchronous transmission assembly is connected to the side shift motor 91. The side shift synchronous belt 92 is driven to rotate by the synchronous transmission assembly. A sample synchronous clamp 93 is fixedly connected to the sample placement frame 9. The sample synchronous clamp 93 is clamped on the side shift synchronous belt 92. The distance sensor 8, the detection transmission assembly, the test paper lifting mechanism and the side shift motor 91 are all electrically connected to the main controller 2. The tensioning adjustment component is arranged on one side of the side shifting motor 91 close to the side shifting synchronous belt 92 and is mounted on the side shifting synchronous belt 92. After working for a period of time, the side shifting synchronous belt 92 is stretched and loosened, and is prone to slipping. The tensioning adjustment component must be used to readjust the tension to ensure the speed of the sample entering and exiting sideways.

[0032] Through the above technical solution, the test strip cover plate 52 is connected to the test strip carrier 5. The total controller 2 controls the test strip lifting mechanism to drive the test strip carrier 5 to extend out of the housing 1, and controls the side shift motor 91 to drive the synchronous transmission component to drive the side shift synchronous belt 92 and the specimen synchronous clamp 93 clamped on the side shift synchronous belt 92 to move horizontally, thereby driving the specimen placement rack 9 out of the housing 1. Insert the test strip into the test strip cartridge 51, and then place the specimen on the specimen placement rack 9. Move the placed test strip and specimen to the designated position through the test strip lifting mechanism, the side shift motor 91 and the side shift synchronous belt 92, so that the test strip is completely immersed in the specimen for reaction. The specimen enters directly from the side, avoiding replacing and placing the specimen by repeatedly opening and closing the housing 1, improving the operation convenience and shortening the incubation process time. The electric heater and the temperature sensor 7 are used in combination to ensure that the test strip is in the most suitable constant temperature state for improving the reaction rate during the reaction, so that the biological reaction or chemical reaction is accelerated and more sufficient, and the reaction linearity is more stable. After the reaction acceleration is completed, the total controller 2 controls the detection transmission component to drive the detection head 4 to move, and controls the movement and positioning of the detection head 4 through the distance sensor 8, and sequentially detects each test strip. During the detection, the test strip lifting mechanism drives the test strip to move up and down, so that the detection head 4 can detect the reaction result of the test strip without omission, improving the detection accuracy and thus improving the work efficiency.

[0033] The synchronous transmission component includes a main transmission wheel 97 and two sub-transmission wheels 98. The main transmission wheel 97 is sleeved on the output end of the side shift motor 91. The two sub-transmission wheels 98 are rotatably connected to the inner bottom of the housing 1. The main transmission wheel 97 and the two sub-transmission wheels 98 are both rotatably connected to the inner side of the side shift synchronous belt 92 and are arranged in parallel. The two sub-transmission wheels 98 are on the same horizontal line. The main transmission wheel 97 is located between the two sub-transmission wheels 98 and is higher than the two sub-transmission wheels 98. By controlling the side shift motor 91 to start through the total controller 2, the main transmission wheel 97 is driven to rotate and drives the side shift synchronous belt 92 to rotate with the cooperation of the two sub-transmission wheels 98, so that the specimen placement rack 9 is driven to move in and out laterally by the specimen synchronous clamp 93 clamped on the side shift synchronous belt 92, facilitating the placement and replacement of the specimen during incubation and detection and improving the work efficiency.

[0034] The tension adjustment assembly includes a tension adjustment wheel 94, a tension fixing wheel 95 and a roller fixing bracket 96. The roller fixing bracket 96 is fixedly connected to the side shift motor 91. The tension adjustment wheel 94 and the tension fixing wheel 95 are respectively located on both sides of the main drive wheel 97. The tension adjustment wheel 94 and the tension fixing wheel 95 are rotatably connected to the outer side of the side shift synchronous belt 92. The tension fixing wheel 95 is rotatably connected to the roller fixing bracket 96. A driving block is rotatably connected to the tension adjustment wheel 94, and the driving block is bolted to the roller fixing bracket 96. A slot hole 101 for position adjustment and a corresponding threaded hole are provided on the roller fixing bracket 96. After working for a period of time, the side shift synchronous belt 92 is stretched and loosened, and it is easy to slip. The tension must be readjusted through the tension adjustment assembly. At this time, the bolt fixing the driving block needs to be loosened, and the position of the tension adjustment wheel 94 is readjusted according to the situation of the side shift synchronous belt 92. After adjustment, the driving block is fixed again. By adjusting the tension, it is ensured that the side shift synchronous belt 92 always remains taut, so as to ensure the speed of the specimen entering and exiting from the side.

[0035] The detection drive assembly includes a detection motor 41 and a detection transmission belt 42. The detection motor 41 is fixedly connected to the detection fixing bracket 44. The detection motor 41 drives the detection transmission belt 42 to rotate. A detection fixing clip 43 is clamped on the detection transmission belt 42. The detection head 4 is fixedly connected to the detection fixing clip 43. The detection motor 41 is electrically connected to the total controller 2. When it is necessary to detect the reaction result after the reaction is completed, the total controller 2 controls the detection motor 41 to drive the detection transmission belt 42 to rotate. The rotation of the detection transmission belt 42 drives the detection fixing clip 43 and the detection head 4 fixed thereon to move. The reaction result of the test paper is sequentially read and detected by the cooperation of the detection head 4 and the distance sensor 8.

[0036] A plurality of cartridge slots 10 are provided on the test paper carrier 5.

Each test paper cartridge 51 is correspondingly arranged in the cartridge slot 10. Two slot holes 101 are provided in each cartridge slot 10, and a magnet block 102 is fixedly connected in each slot hole 101. The test paper cartridge 51 and the magnet block 102 are magnetically attracted to each other. The iron test paper cartridge 51 is adsorbed by the magnet block 102, and the two are adsorbed and fixed magnetically, which is convenient for removing the test paper cartridge 51 to insert and place the test paper, and is also convenient for replacing the worn test paper cartridge 51, and at the same time does not affect the fixation of the test paper.

[0037] The test strip lifting mechanism includes a servo stepper motor 53, a lead screw nut 54 that drives the test strip carrier 5 to lift, and a vertically arranged lifting lead screw 55. The servo stepper motor 53 is fixedly connected to the inner bottom of the housing 1. The lifting lead screw 55 is coaxially and fixedly connected to the output shaft of the servo stepper motor 53. The lead screw nut 54 is rotatably connected to the lifting lead screw 55. The test strip carrier 5 is fixedly connected to the lead screw nut 54. The servo stepper motor 53 is electrically connected to the main controller 2. By controlling the servo stepper motor 53 through the main controller 2 to drive the lifting lead screw 55 to rotate, the lead screw nut 54 is driven to move up and down on the lifting lead screw 55, thereby driving the test strip carrier 5 to extend out of the housing 1 to place the test strip, and can also drive the test strip until the test strip reacts with the sample, and drives the test strip to move up and down when the detection head 4 performs detection after the reaction ends to identify the reaction result without omission. The servo stepper motor 53 controls all operations, simplifies the overall detection operation, and improves the detection accuracy and efficiency.

[0038] On both side walls of the test strip carrier 5, there are respectively fixedly connected with carrier slide rails 56. On each carrier slide rail 56, there is slidably connected a test strip holder seat 57. On each test strip holder seat 57, there is opened a carrier chute adapted to the corresponding carrier slide rail 56, and the carrier slide rail 56 is slidably connected in the corresponding carrier chute. Through the cooperation of the carrier slide rail 56 and the carrier chute opened on the test strip holder seat 57, the stability of the test strip carrier 5 during up and down movement is improved, the accuracy of the detection head 4 for result identification is ensured, and the detection accuracy is provided.

[0039] Above the housing 1, there is opened a test strip insertion port 111. The test strip carrier 5 is slidably connected at the test strip insertion port 111. The edge of the test strip insertion port 111 is rotatably connected with an upwardly flipping cover plate 11. Setting the upwardly flipping cover plate 11 can prevent dust from entering the interior of the fluorometer and also facilitate the insertion of the test strip, improving the convenience of operation.

[0040] When the pre-treatment incubation fluorometer is in use, the upper flip cover 11 is opened. Under the control of the main controller 2, the servo stepping motor 53 is started, driving the lifting lead screw 55 to rotate, causing the lead screw nut 54 to move on the lifting lead screw 55, driving the test strip carrier 5 to rise and extend out of the test strip insertion port 111. At the same time, the main controller 2 controls the side shift motor 91 to act. The side shift motor 91 drives the side shift synchronous belt 92 to drive the sample placement rack 9 to extend out from the side wall of the housing 1 through the sample synchronous clamp 93. Multiple samples are placed on the sample placement rack 9, and then multiple test strips are inserted into the test strip cartridge 51 in sequence. The main controller 2 then controls the servo stepping motor 53 to drive the test strip carrier 5 to descend, and at the same time controls the side shift motor 91 to act to drive the sample placement rack 9 with samples into the interior of the fluorometer until the test strip can extend into the corresponding sample for a complete reaction. When the test strip carrier 5 rises, the main controller 2 energizes and heats the electric heating plate 6. The temperature sensor 7 senses the temperature of the reaction area, maintaining the most suitable reaction temperature to accelerate and make the biological reaction or chemical reaction more sufficient, and the reaction linearity is more stable. A cooling fan is also provided inside the housing 1, and the cooling fan is also electrically connected through the main controller 2. When the temperature sensor 7 senses that the temperature of the reaction area is too high, the cooling fan starts to dissipate heat to quickly cool down to ensure a continuous constant temperature state and improve the incubation efficiency. After the reaction is completed, the detection motor 41 and the detection transmission belt 42 cooperate to drive the detection head 4 clamped on the detection transmission belt 42 through the detection fixing clamp 43 to move. The distance sensor 8 senses the moving position of the detection head 4. When the detection head 4 moves to the corresponding test strip, the servo stepping motor 53 drives it to move up and down to ensure that the detection head 4 can recognize all reaction results. Then the above operations are repeated in sequence, improving the accuracy of the detection results, greatly shortening the time for experimental operation and detection, and improving the work efficiency.
