Description

Technical Field

[0001] This utility model relates to the field of syphilis testing technology, specifically to an automated syphilis testing device. Background Technology

[0002] Treponema pallidum antibodies are specific antibodies that appear in the serum after Treponema pallidum invades the human body. They are the main markers for syphilis infection and monitoring. Clinically, Treponema pallidum antibody test kits (hereinafter referred to as kits) are commonly used to test whether samples are infected with syphilis. However, there is no corresponding syphilis testing device in the current technology to cooperate with the kits for testing. It requires manual operation by medical staff, which has the disadvantages of large workload and low efficiency. Moreover, the test results cannot be judged and stored, which is prone to misjudgment.

[0003] To address the aforementioned technical issues, patent document CN215263564U discloses an automated syphilis testing device. In specific operation, a pipette, driven by a controller and corresponding actuators, adds 4 drops (100 μL) of serum diluent to the first well of the reagent kit, followed by 1 drop (25 μL) to each of the second to fourth wells. The pipette is used to measure 25 μL of sample. The pipette then adds 25 μL of sample to the first well, and then dilutes the sample from the first well to the fourth well using a 2n dilution method. One drop (25 μL) of unsensitized particles is added to the third well, and one drop (25 μL) of sensitized particles is added to the fourth well. The controller activates a mixing vibrator to mix the reagents and sample in the reagent kit. After adding the test reagents and sample, the reagent kit is placed in a constant temperature and humidity chamber and left to stand for two hours. After the settling time is complete, medical personnel transfer the settled sample to an observation chamber for observation. This technical solution involves setting up a pipette tip replacement box, a fourth slot, a fifth slot, and an automatic clamping device to replace pipette tips. During the process of adding test reagents and samples, this technical solution uses only one pipette to add test reagents and samples into the reagent kit. Furthermore, there are three types of test reagents in this technical solution. The pipette tip needs to be replaced every time liquid is added to the reagent kit. Therefore, the pipette tip needs to be replaced frequently, resulting in low testing efficiency. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1: Refer to Figures 1-5 As shown, an automated syphilis testing device includes a platform 1, a terminal 22 fixed on the platform 1, and a controller mounted on the platform 1. The terminal 22 and the controller are electrically connected. The terminal 22 is a PC, and the controller is a microcontroller or a PLC.

[0026] Platform 1 has two parallel guide rails 8 fixed on it, each containing a first drive unit. Platform 1 also has two inverted U-shaped movable frames 9, symmetrically arranged, slidably connected to the two guide rails 8. Each movable frame 9 is connected to the first drive unit within the guide rails 8. A second drive unit is located at the upper end of each movable frame 9, and a support plate 10 is slidably mounted on the upper end of each frame 9. The second drive unit is connected to the support plate 10 on one side of each frame. The first drive unit, the second drive unit, and the controller are electrically connected.

[0027] Specifically, the first drive unit includes a lower lead screw 11 located in the guide rail 8. A first motor 17 is fixed at one end of the guide rail 8. The output shaft of the first motor 17 is concentrically fixedly connected to the lower lead screw 11 on one side. The first motor 17 is electrically connected to the controller through the control module. The two moving frames 9 are threadedly connected to the two lower lead screws 11 respectively.

[0028] In this embodiment, the left movable frame 9 is threadedly connected to the front lower lead screw 11, and the right movable frame 9 is threadedly connected to the rear lower lead screw 11.

[0029] The second drive unit includes an upper screw 903 rotatably mounted in the upper end of the movable frame 9. A second motor 901 is fixed to one end of the movable frame 9. The output shaft of the second motor 901 is concentrically fixedly connected to the upper screw 903 on one side of the motor. A slider 902 is slidably mounted in the upper end of the movable frame 9. The slider 902 is threadedly connected to the upper screw 903 on one side of the motor. A support plate 10 is fixed on the slider 902. The second motor 901 is electrically connected to the controller through a control module.

[0030] Three pipetting units are fixed to the lower end of the left support plate 10, and one pipetting unit is fixed to the lower end of the right support plate 10. The pipetting units are electrically connected to the controller.

[0031] The pipetting unit includes a connecting plate 12, which is fixed to a support plate 10 on one side. The lower end of the connecting plate 12 is fixedly connected to the upper end of the upper electric telescopic rod 13. The lower end of the upper electric telescopic rod 13 is fixedly connected to the upper end of the inverted U-shaped mounting bracket 14. A pipette 15 is installed inside the mounting bracket 14. The lower end of the pipette 15 passes through the lower end of the mounting bracket 14 and is fixedly connected to the lower end of the mounting bracket 14. A lower electric telescopic rod 16 is installed inside the upper end of the mounting bracket 14. The upper end of the lower electric telescopic rod 16 is fixedly connected to the upper end of the mounting bracket 14 and the lower end of the lower electric telescopic rod 16 is fixedly connected to the upper end of the piston rod of the pipette 15. The lower electric telescopic rod 16 and the upper electric telescopic rod 13 are electrically connected to the controller through a control module.

[0032] When the upper electric telescopic rod 13 is activated, the mounting bracket 14, the lower electric telescopic rod 16, and the pipette 15 descend. When the lower electric telescopic rod 16 is activated, the piston rod of the pipette 15 can move up or down. When the piston rod of the pipette 15 moves up, the reagent can be drawn into the pipette 15; when the piston rod of the pipette 15 moves down, the reagent can be discharged from the pipette 15.

[0033] Platform 1 between the two guide rails 8 is provided with a first groove 2, a second groove 4, and a third groove 6. Test reagents 3 are placed in the first groove 2, and there are three first grooves 2. The three pipetting units at the lower end of the support plate 10 on the left side correspond one-to-one with the three first grooves 2. The test reagents 3 in the three first grooves 2 are serum diluent, unsensitized particles, and sensitized particles, respectively.

[0034] The second groove 4 contains the reagent kit 5, and the third groove 6 contains the specimen rack 7. The second groove 4 is located between the first groove 2 and the third groove 6. A mixing vibrator is installed at the bottom of the second groove 4, and the mixing vibrator is electrically connected to the controller via a control module.

[0035] The platform 1 on one side of the third slot 6 is provided with a fourth slot 18 and a fifth slot 20. The fourth slot 18 is detachably and fixedly connected to a gun head replacement box 19, and multiple replacement gun heads are inserted into the upper end of the gun head replacement box 19.

[0036] An automatic clamping device 21 is fixed on the platform 1 on one side of the fifth slot 20. The automatic clamping device 21 is electrically connected to the controller.

[0037] The automatic clamping device 21 includes a housing 211, a fixed clamping plate 212, a movable clamping plate 213, and an electric push rod 214. A clamping opening is provided on one side of the housing 211. The fixed clamping plate 212 and the movable clamping plate 213 are arranged opposite each other, with one end located inside the housing 211 and the other end extending through the clamping opening to the outside of the housing 211. The fixed clamping plate 212 is fixedly connected to the housing 211, and the movable clamping plate 213 is slidably connected to the housing 211. The electric push rod 214 is fixed inside the housing 211 and fixedly connected to the movable clamping plate 213. The electric push rod 214 is electrically connected to the controller via a control module.

[0038] In this embodiment, only the pipette tip of the pipette unit below the right support plate 10 needs to be replaced. For ease of description, the pipette unit below the right support plate 10 is named the right pipette unit. During automatic tip replacement, the right movable frame 9 is driven to move by the first drive unit connected to it, so that the right pipette unit corresponds to the fixed clamp 212 and movable clamp 213 of the automatic clamping device 21. Then, the second drive unit on the right movable frame 9 is activated, causing the right pipette unit to move back and forth until it moves above the space between the fixed clamp 212 and movable clamp 213. Then, the pipette 15 of the right pipetting unit is moved downwards. When the pipette tip of the right pipetting unit 15 is between the fixed clamp 212 and the movable clamp 213, the electric push rod 214 is activated, causing the fixed clamp 212 and the movable clamp 213 to move closer together and clamp the pipette tip between them. This causes the pipette 15 of the right pipetting unit to move upwards, and the pipette tip of the right pipetting unit 15 is pulled off. Then, the fixed clamp 212 and the movable clamp 213 move away from each other, and the pulled-off pipette tip falls into the fifth groove 20.

[0039] Then, the pipette 15 of the right pipetting unit is moved upwards, causing the right-side movable frame 9 to move. After the pipette 15 of the right pipetting unit is positioned directly above a pipette tip on the tip changing box 19, the pipette 15 of the right pipetting unit is moved downwards, allowing a pipette tip from the tip changing box 19 to be inserted into the pipette 15 of the right pipetting unit. Then, the pipette 15 of the right pipetting unit is moved upwards. At this point, an unused pipette tip is installed on the pipette 15 of the right pipetting unit, and the pipette tip replacement of the right pipetting unit 15 is complete.

[0040] For ease of description, in this embodiment, the three pipetting units below the left-side support plate 10 are named the first pipetting unit, the second pipetting unit, and the third pipetting unit, respectively. The first pipetting unit adds serum diluent to the kit 5, the second pipetting unit adds unsensitized particles to the kit 5, and the third pipetting unit adds sensitized particles to the kit 5.

[0041] The specific operating steps during testing are as follows: (1) The controller controls the first motor 17 on the front side, thereby causing the left movable frame 9 to move on the guide rail 8. When the first pipetting unit is aligned with the first tank 2 containing the serum diluent, the first motor 17 on the front side is turned off. Then, the pipette 15 of the first pipetting unit moves downward. After the tip of the pipette 15 of the first pipetting unit is inserted into the serum diluent, the pipette 15 of the first pipetting unit draws up the serum diluent. Then, the controller controls the first motor 17 on the front side, thereby causing the left movable frame 9 to move on the guide rail 8. In conjunction with the second motor 901 at the upper end of the left movable frame 9, the tip of the pipette 15 of the first pipetting unit is positioned above the first well of the reagent kit 5. Then, the pipette 15 of the first pipetting unit drips the serum diluent into the first well of the reagent kit 5, a total of 4 drops (100 μL). 1 drop (25 μL) is dripped from the second well to the fourth well. The quantitative amount of the pipette 15 of the first pipetting unit is 25 μL.

[0042] (2) The controller controls the first motor 17 on the rear side, which in turn causes the right-side movable frame 9 to move on the guide rail 8. In conjunction with the second motor 901 at the upper end of the right-side movable frame 9, when the pipette tip of the right pipetting unit 15 aligns vertically with the sample in the specimen holder 7, the first motor 17 on the rear side and the second motor 901 at the upper end of the right-side movable frame 9 are turned off. Then, the pipette tip of the right pipetting unit 15 moves downwards, inserting into the sample and drawing up the sample. The pipette tip of the right pipetting unit 15 draws up 25 μL of sample. Then, in conjunction with the first motor 17 on the rear side and the second motor 901 at the upper end of the right-side movable frame 9, the pipette tip of the right pipetting unit 15 moves and adds the sample to the first well of the kit 5, then dilutes it from the first well to the fourth well in a 2n manner.

[0043] Using pipette 15 of the second pipetting unit, add one drop (25 μL) of unsensitized particles to the third well of kit 5. Using pipette 15 of the third pipetting unit, add one drop (25 μL) of sensitized particles to the fourth well of kit 5.

[0044] (4) The controller starts the mixing shaker to mix the mixture in kit 5.

[0045] Then, reagent kit 5 was placed in a constant temperature and humidity environment and left to stand for two hours. After that, medical staff observed the mixture in reagent kit 5 after it had been left to stand and made a judgment.

[0046] When interpreting the results, no agglutination was observed in the third well of kit 5, while a 1+ to 2+ agglutination reaction was observed in the fourth well of kit 5, and a positive result was reported.

[0047] No agglutination reaction was observed in well 3 and well 4 of kit 5, and the results were reported as negative.

[0048] No agglomeration was observed in the third well of kit 5, but soil agglomeration was observed in the fourth well of kit 5, resulting in a weak positive report.

[0049] This invention, by setting three pipetting units below the support plate 10 on the left side, allows the three pipetting units to add the test reagents 3 from the three first tanks 2 to the reagent kit 5 respectively. During the mixing process of the test reagents 3 and the sample, there is no need to replace the pipette tips 15 of the three pipetting units on the left side, which can improve the testing efficiency, reduce the amount of pipette tips used, and reduce the testing cost.

[0050] Example 2: Based on Example 1, a constant temperature and humidity chamber is fixed at the lower end of the platform 1, and an observation box is fixed at the lower end of the constant temperature and humidity chamber. A high-definition camera is installed inside the observation box, and the terminal 22 is electrically connected to the high-definition camera.

[0051] After mixing reagent 3 and the sample, reagent kit 5 is placed in a constant temperature and humidity chamber for two hours. The chamber provides a suitable reaction temperature to ensure the accuracy of the test results. After two hours, medical staff transfer reagent kit 5 to an observation chamber for observation.

[0052] A high-definition camera is used to capture images of the samples within reagent kit 5 after reaction and sends these images to terminal 22. Terminal 22 receives and saves the images. Terminal 22 also compares the received images with pre-stored images; if the comparison does not match, the result is considered positive. Terminal 22 also displays the received images and, upon user request, magnifies the images and modifies the judgment result. Terminal 22 is also electrically connected to the controller to set the number of samples to be tested.

[0053] A high-definition camera is used to capture image information of the samples in reagent kit 5 after the reaction, and sends the image information to terminal 22. Terminal 22 receives and saves the image information, serving as data storage for subsequent data retrieval, printing, and other operations. Terminal 22 also compares the received image information with pre-stored image information. If the comparison result does not match, the result is judged as positive. In addition, terminal 22 is also used to display the received image information and, according to user requests, to magnify the image information and modify the judgment result. By combining machine judgment and manual judgment, the accuracy of test results is effectively improved. When medical staff find a difference between the machine judgment result and the manual judgment result, the test result can be re-examined. If the machine judgment is confirmed to be incorrect, the judgment result can be modified through terminal 22, effectively reducing the false judgment rate.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
