Mycobacterium tuberculosis infection in the lungs can cause a chronic respiratory infectious disease. Mycobacterium tuberculosis is transmitted to healthy people by pulmonary tuberculosis patients who excrete bacteria through loud talking and coughing droplets.
[0003] The T-cell spot test for tuberculosis infection uses tuberculosis-specific mixed antigens A and B to stimulate the tuberculosis-specific activated T lymphocytes present in the peripheral blood mononuclear cells of tuberculosis-infected patients to secrete gamma interferon.

However, in the current test process, there are problems in that sample processing is mainly manual, the operation steps are cumbersome, and the time cost is high.

A protective component 15 that integrates the functions of sealing and unsealing is provided on one side of the carrier 1. A screw moving component 16 is provided on one side of the protective component 15. A second suction component 17 is provided on the screw moving component 16. The specific components of the second suction component 17 are the same as those of the first suction component 14. Their functions are to first clamp the disposable medical straw, The air inside the rubber head is expelled by simulating manual kneading, and then the straw is placed in the target material to be sucked, and then the kneading mechanism 18 is used to loosen it to complete the corresponding suction action. When the target material is stored in the straw, it is placed in the appropriate position according to the next working process, and then the kneading mechanism 18 is controlled to simulate kneading to complete the discharge of the target material, ensuring the working process. As for the screw cylinder assembly, it provides a prerequisite for driving the second suction assembly 17 to move closer to or away from the rotating disk 3 to achieve the suction or discharge of the material, ensuring the working process;
[0031] The specific work flow is described as follows: when using the automatic aspiration device body mentioned in this embodiment to carry out the corresponding T lymphocyte aspiration work, the equipment needs to be placed in a sterile environment that complies with the processing flow to prevent the possibility of external factors affecting the test results. When in use: a certain amount of centrifuge tubes 44 are placed in the centrifuge tube loading assembly 5, and the centrifuge tube loading assembly 5 is used to arrange multiple centrifuge tubes 44 neatly, and with the help of the first clamping cylinder 57, they are placed in the loading shell 7 of the conveyor belt mechanism 6, and then the conveyor belt mechanism 6 transports the loading shell 7 and the centrifuge tube 44. When it moves to the position of the reaction reagent adding assembly 9, the conveyor belt mechanism 6 stops conveying and waits for the reaction reagent to be injected into the centrifuge tube 44. After the reaction reagent is added, the conveyor is The belt mechanism 6 continues to run, and when it moves to the upper tube mechanism 8, the upper tube mechanism 8 transports the above components together to the centrifugal assembly 4 of the rotating disk 3, and then controls the rotating disk 3 to rotate, and transports the centrifuge tube 44 containing the reaction reagent to a position close to the first suction assembly 14, and under the action of the multi-directional adjustment assembly 13, it realizes adjustment at different positions. During the rotation of the above-mentioned centrifuge tube 44, the sample loading assembly 10 receives the sample tube and inputs it into the rotating disk 103. Relying on its rotation, it drives the sample to move toward a position close to the material holding mechanism 11. When the sample tube arrives at the position close to the material holding mechanism 11, the transfer mechanism 12 is controlled to operate so that it clamps the sample tube and cooperates with another transfer mechanism 12 to realize The end caps of the sample tubes are removed and placed in the material holding mechanism 11. The front transport mechanism 12 continues to perform the clamping action, and the rear transport mechanism 12 first outputs the end caps outward. In this process, after the first suction component 14 completes the suction of the sample under the action of the multi-directional adjustment component 13, the rear transport mechanism 12 outputs the sample tube outward. Of course, the above-mentioned export position is a centralized position to avoid contamination. The first suction component 14 containing the sample moves toward the rotating disk 3 and places the sample in the centrifuge tube 44. It then puts the disposable straw into a unified position and clamps a new disposable straw from the outside, waiting for the next processing step. The centrifuge tube 44 containing the sample and reaction reagent continues to rotate with the rotating disk 3 until it is close to the rotating disk 3. At the position near the protective component 15, the upper end of the centrifuge tube 44 is sealed by the protective component 15. After the sealing work is completed, centrifugal processing is carried out. After the centrifugal processing is completed, the end cover is removed by the protective component 15 and collected and guided to a unified position. The centrifuge tube 44 after centrifugation continues to rotate. When it rotates to a position close to the second suction component 17, the screw moving component 16 drives the second suction component 17 to approach the rotating disk 3, and inserts the suction pipe into the centrifuge tube 44 in an inclined manner, and corresponds to the target material layer. Repeat the simulated manual kneading action to achieve the suction of the target material and ensure the working process. After the target material layer is sucked, the screw moving component 16 is controlled to adjust the position of the second suction component 17.The target material layer is output to the designated collection position. As for the centrifuge tube 44 after the target material layer is taken out, it continues to rotate. After it rotates to the idle position of the loading platform, a manipulator can be set up outside to take out the loading shell 7 and the centrifuge tube 44 in the centrifuge assembly 4 together. The centrifuge assembly 4 continues to work. Under the influence of the inside of the loading shell 7, after it is taken out as a whole, it can press down on the top of the centrifuge tube 44 to separate it from the loading shell 7, and the centrifuge tube 44 is collected centrally. The loading shell 7 can be transported back to the conveyor belt mechanism 6 to realize a closed processing loop, which greatly improves the functionality of the device and meets the use requirements.
[0032] In the above process, the rotating disk 3 is used to receive the centrifuge tube 44 containing the reaction reagents and samples, and the centrifugal treatment thereof is centralized and transferred to each processing step to ensure the smooth progress of the processing. The sample loading assembly 10, the transfer mechanism 12, the multi-directional adjustment assembly 13 and the first suction assembly 14 are used to cooperate with each other to conveniently place the sample into the centrifuge tube 44 containing the reaction reagent, replacing the manual sampling and placement of the sample, thereby improving the work process and avoiding contamination of the sample. The protective assembly 15 is used to provide the prerequisite for the centrifugal processing of the sample and ensure the use requirements. The second suction assembly 17 is used to conveniently absorb the required sample layer in the centrifuge tube 44 after the reaction and output it to a designated location, thereby improving the work process.

It can realize batch processing of multiple samples, replacing the inconvenience of manual operation one by one, improving work efficiency and cell extraction purity, and reducing the impact of human operation on the results, reducing contamination, ensuring the accuracy of the detection effect, and effectively meeting the use requirements.

A third vertical cylinder 1232 is provided on the moving seat 1231. The output end of the cylinder 1232 is provided with a horizontal support plate 1233 of L-shaped design, and a second horizontal cylinder 1234 is provided on the inner side of the horizontal support plate 1233. The output end of the second horizontal cylinder 1234 is provided with a T-shaped plate 1235. A first hollow rotating platform 1236 is provided below the T-shaped plate 1235. The output end of the first hollow rotating platform 1236 is provided with a connecting plate 1237. The third clamping cylinder 1238 is provided on the connecting plate 1237. The specific description is as follows: after the conveyor belt assembly 101 transports the sample to the rotating material tray 103, as the rotating material tray 103 rotates, it gradually moves to the position close to the material holding mechanism 11. Position, when a sample reaches the above position, the transport assembly 123 on the right side is operated, and the cooperation between the third vertical cylinder 1232, the second horizontal cylinder 1234 and the third clamping cylinder 1238 is used to clamp the sample tube and move it to a position close to the carrying mechanism. Since the sample tube generally has an end cap, another transport assembly 123 is used to control its third clamping cylinder 1238 to approach the end cap of the sample tube and clamp it, and respectively control the two first hollow rotating platforms 1236 to rotate, and the two rotation directions are opposite, so as to remove the end cap of the sample tube. After the end cap is removed, the transport assembly holding the end cap is clamped. 123 outputs the end cap to the outside, and another transfer component 123 places the sample tube on the material holding mechanism 11, waiting for the sample to be absorbed. After the transfer component 123 places the sample tube on the material holding mechanism 11, it performs the work of clamping the next sample tube. At this time, the previous transfer component 123 waits for the completion of sample absorption after outputting the end cap to the designated position, and then clamps the sample tube after sampling, and outputs it to the external centralized position again. This reciprocating process not only realizes the convenient loading of the sample tube, but also can output each tool to the designated position in a classified manner, greatly improving the functionality of the device and ensuring usage needs.
[0039] In order to realize convenient suction of samples and ensure that its working process complies with the operating specifications, the multi-directional adjustment component 13 includes a synchronous belt longitudinal movement component 131. As for the synchronous belt longitudinal movement component 131, it includes two driving wheels, and a synchronous belt is set between the two driving wheels. The two ends of the synchronous belt are respectively connected to the bottom of the screw rod transverse movement component 132. In this way, the driving wheel drives the synchronous belt to rotate and act on the screw rod transverse movement component 132 to realize convenient adjustment of its longitudinal position. A screw rod transverse movement component 132 is set above the synchronous belt longitudinal movement component 131, and its output end is connected to the first suction component 14. The establishment of the screw rod transverse movement component 132 utilizes the rotation of the ball screw in the prior art to realize the translational movement of the equipment. The above-mentioned devices are all existing mature and conventional technical means, and the specific working principle will not be repeated. In this embodiment, the cooperation between the above-mentioned two devices can, on the one hand, facilitate the first suction component 14 to clamp the external disposable medical pipette and put it into the sample suction. During the sampling process, the sample after sampling is output to the centrifuge tube 44. On the other hand, the disposable straw that has completed the work can be output to the outside, waiting for the subsequent clamping of a new disposable straw, thereby ensuring the relative sterility during the sample processing process and the accuracy of the test results. Furthermore, the first suction component 14 includes an L-shaped mounting plate 141, wherein a hollow rotating platform is also provided between the bottom of the mounting plate 141 and the output end of the screw lateral movement component 132, for adjusting the circumferential position of the first suction component 14 to meet the needs of different processing operations. For example, when clamping a disposable medical straw from the outside, the fourth clamping cylinder 147 faces outward. When the sample is sucked from the sample tube, its position is adjusted to the material holding mechanism 11 by rotation. When the sample needs to be discharged, the fourth clamping cylinder 147 can be rotated to face the rotating disk 3. Of course, the fourth clamping cylinder 147 can also be not directed toward the rotating disk 3. When the sample is output, it is only necessary to ensure that the second hollow rotating platform 144 can tilt the straw.A slide bar 1411 is provided on the rear side of the mounting plate 141, which limits the lifting direction of the movable plate 142 and ensures its smoothness during movement. A movable plate 142 with an L-shaped design is provided on one side of the slide bar 1411, and a fourth vertical cylinder 143 for driving the movable plate 142 is provided on the mounting plate 141. A second hollow rotating platform 144 is provided on one side of the movable plate 142, and a rotating tube 145 is provided at the output end of the second hollow rotating platform 144, and passes through the inside of the second hollow rotating platform 144 to the outside of the movable plate 142, a rotating plate 146 is provided on the outside of the rotating tube 145, and a fourth clamping cylinder arranged perpendicular to the rotating plate 146 is provided below the rotating plate 146 147. The kneading mechanism 18 is located within the rotating plate 146 above the fourth clamping cylinder 147. Specifically, the extension and retraction of the fourth vertical cylinder 143 is used to drive the movable plate 142 to different vertical positions, facilitating its aspiration of samples from the sample tube. The second hollow rotating platform 144 is configured to adjust the vertical angles between the fourth clamping cylinder 147 and the kneading mechanism 18. This allows the lower end of the fourth clamping cylinder 147 to tilt and contact the sidewall of the sample tube or centrifuge tube 44 when clamping a medical pipette. This complies with existing operating technical specifications, ensures convenient sample aspiration and delivery, and safeguards the work process.
[0040] In order to ensure the effective implementation of the suction action, the kneading mechanism 18 includes a stepping motor 181, and the output end of the stepping motor 181 is provided with a driving gear 182, and a driving gear 183 meshing with it is provided on the lower side of the driving gear 182, and a driven gear 184 meshing with it is provided on one side of the driving gear 183. The teeth on the driving gear 183 and the driven gear 184 are both arc-shaped, and the geometric centers of the driving gear 183 and the driven gear 184 are provided with a rotating shaft 185. The outer side of the rotating shaft 185 is provided with an eccentric wheel 186, and the left and right eccentric wheels 186 are arranged in a mirror image. The specific description is: when the fourth clamping cylinder 147 in the first suction component 14 clamps the disposable medical straw, the top of the medical straw, that is, the rubber head of the straw, corresponds to the position of the kneading mechanism 18, and the first Before the suction component 14 enters the sample tube, the stepper motor 181 is first controlled to operate, the driving gear 182 rotates and acts on the active gear plate 183, and the driven gear plate 184 engages with it, thereby driving the rotating shaft 185 to rotate, and further acts on the eccentric wheel 186. The big heads of the left and right eccentric wheels 186 are close to each other and act on the rubber head to discharge the internal air. When the pipette enters the sample tube, the stepper motor 181 is controlled to operate in the reverse direction, and the big head of the eccentric wheel 186 rotates outward, so that the sample in the sample tube can be sucked. After the sample is transported to the centrifuge tube 44 with the pipette, the stepper motor 181 is controlled to operate again to perform the air discharge action, that is, the sample can be output to the centrifuge tube 44, providing convenient conditions for the subsequent centrifugal processing of the sample and reagent, and ensuring usage requirements.

Specifically, the protection component 15 is established in a similar manner to the working principle of the centrifuge tube loading component 5. The capping machine 151 in the prior art is used to deliver the cap that can be adapted to the upper tube mouth of the centrifuge tube 44, so that it can be placed on or detached from the centrifuge tube 44 in a plug-in manner. That is, the tube loading machine 51 delivers each cap to its output end, and uses the second longitudinal cylinder 153 to adjust the longitudinal position of the suction cup 157. , and then use the operation of the fifth vertical cylinder 155 to make the suction cup 157 suck the cover, and then under the action of the second longitudinal cylinder 153, make the cover close to the centrifuge tube 44, and with the help of the fifth vertical cylinder 155, press the cover on the centrifuge tube 44 to complete the sealing of the tube, ensuring the smooth progress of subsequent centrifugation. When the centrifugation is completed, adjust the suction effect of the suction cup 157, pull the cover out from above the centrifuge tube 44 after centrifugation, and then, with the cooperation of each cylinder, guide the used cover out from the discharge hole 1511. Of course, a material holding box or an inclined discharge plate can be installed below the discharge hole 1511 to collect the used caps in a centralized manner and improve the work process.
