Description

Technical Field

[0001] The present invention relates to the field of medical detection technology, and in particular to a puncture sampling specimen sorting device. Background Art

[0002] Aspiration sampling is a medical procedure that is usually used to obtain tissue samples by puncturing the body with a needle in order to diagnose or evaluate the disease. For example, some infectious diseases, such as unexplained lung infection, abdominal infection, osteomyelitis, etc., require puncture to extract pus, secretions or tissue fluid from the corresponding parts for smear, culture and drug sensitivity testing. This can determine the pathogens of infection and sensitive antibiotics, and provide a basis for clinical treatment. In some cases, the specimens after puncture sampling need to be subsampled for different tests or analyses (such as pathological examination, cytological examination, molecular biology test, etc.).

[0003] Since the amount of specimens taken by puncture sampling is small, in order to perform different tests or analyses on the specimens, the specimens need to be diluted first to facilitate subsequent sample division and testing. However, the existing sample division device for puncture sampling specimens cannot automatically and stably dilute the sampled specimens during actual work, and cannot conveniently adjust the number of divided samples according to actual needs, and thus cannot perform convenient and accurate equal sample division of the diluted specimens. The practicability and applicability are poor, and the work efficiency is low. Moreover, the existing sample division device for puncture sampling specimens cannot ensure the stability and safety of the working state during actual work, and cannot perform convenient splitting, cleaning and safety protection work after the work is completed. Therefore, it is necessary to provide a sample division device for puncture sampling specimens to meet the needs of users. Summary of the invention

[0028] In this embodiment, four second fixing tubes 15 are provided, and the four second fixing tubes 15 are evenly distributed around the mounting plate 1. The top surface of the second fixing tube 15 is flush with the top surface of the mounting plate 1, and the top surface of the mounting plate 1 and the top surface of the connecting rod 20 are both in contact with the bottom surface of the protective shell 12. The second fixing tube 15 corresponds to the support plate 16 and the rubber suction cup 17 one by one, respectively. The bottom surface height of the rubber suction cup 17 is lower than the bottom surface height of the support plate 16. The connecting rod 20 is fixed to the middle part of the top of the second rubber piston 19. Under the cooperation of the second clamping rod 11 and the second clamping groove 13, the clamping and disassembly of the protective shell 12 can be completed conveniently. The installed protective shell 12 can provide convenient protection for the entire device and ensure the convenience of subsequent carrying and transportation of the entire device; when the protective shell 12 is removed and the entire device starts to work, the second strong spring 18 can drive the second rubber piston 19 to move upward automatically under the elastic action of the second strong spring 18. Combined with the rubber suction cup 17 at the bottom of the second fixed tube 15, the negative pressure can be used to automatically and stably adsorb and fix the entire device on the work surface, and the second clamping rod 11 can also be used to clamp and fix the connecting rod 20 on the second rubber piston 19 to ensure the stability of the adsorption state, thereby ensuring the stability and safety of the subsequent working state of the entire device.

[0029] It should be noted that the present invention is a puncture sampling specimen sorting device. First, the staff can place the entire device on the workbench, and then the staff can pull the second clamping rod 11 on the second fixing plate 9 outward until the second clamping rod 11 moves out of the second clamping groove 13 on the protective shell 12. At this time, the protective shell 12 and the mounting plate 1 can be easily separated, and then the staff can remove the protective shell 12. At the same time, after the protective shell 12 is separated from the mounting plate 1, the connecting rod 20 loses its downward thrust. At this time, under the elastic action of the second strong spring 18, the second rubber piston 19 can be driven to move upward automatically, and then the connecting rod 20 can be driven to move upward synchronously. Then the staff can pull the second clamping rod 11 to the side again to prevent the second clamping rod 11 from blocking the movement of the connecting rod 20. When the third clamping groove 21 on the connecting rod 20 can move upward to the second clamping rod 11, the staff can then release the second clamping rod 11. At this time, under the elastic action of the second reset spring 10, the second clamping rod 11 can be driven to automatically move and reset, and stably engage in the third clamping groove 21 on the connecting rod 20, to ensure the stability of the engaging state of the connecting rod 20. Under the movement of the connecting rod 20, the second rubber piston 19 in the second fixing tube 15 can suck the internal gas of the rubber suction cup 17. At this time, negative pressure is formed inside the rubber suction cup 17. By using the negative pressure of each rubber suction cup 17, the device as a whole can be automatically and stably adsorbed and fixed on the workbench, and the second clamping rod 11 can be used to fix the connecting rod 20, so as to ensure the stability of the adsorption state, and thus ensure the stability and safety of the subsequent working state of the device as a whole. Then the staff can rotate the one-way threaded rods 322 on both sides of the top of the first cover plate 320. Under the action of the threaded rotation of the one-way threaded rods 322 on both sides, they can move out of the threaded holes 316 on the limit block 315, so as to conveniently complete the disassembly and separation between the first cover plate 320 and the processing frame 317. When the one-way threaded rods 322 move out of the threaded holes 316, the obstruction of the first cover plate 320 is lost, and the processing frame 317 can also be separated from the sleeve 308. At this time, the staff can clean the processing frame 317. The processing frame 317 after cleaning, drying and sterilization can be placed in the sleeve 308. At this time, each second conveying pipe 325 at the bottom of the processing frame 317 can be stably inserted into the corresponding first positioning groove 329 on the transfer frame 328 and sealed with the sealing ring 330; and during the placement process, Under the limiting action of the limiting block 315, the limiting cylinder 318 in the processing frame 317 can be limitedly inserted on the first conveying tube 314 and the limiting block 315, and then the staff can conveniently convey the puncture sampled specimens and the diluent to the processing frame 317. After the loading is completed, the first cover plate 320 can be covered on the processing frame 317, and the one-way threaded rods 322 on both sides are rotated in the opposite direction. At this time, under the reverse thread rotation action of the one-way threaded rods 322 on both sides, they can be threadedly rotated into the threaded holes 316 on the limiting block 315, and the second cover plate 323 and the second rubber pad 324 on the one-way threaded rod 322 can be used to seal and close the limiting cylinder 318. At this time, the first cover plate 320, the processing frame 317 and the sleeve 308 can be conveniently installed to ensure the stability of the subsequent working state of the processing frame 317 and the sleeve 308. At this time, the staff can drive the servo motors 302 on the first connecting plates 301 on both sides. At this time, under the driving action of the servo motors 302, the turntable 303 can be driven to rotate stably through the output shaft. During the rotation of the turntable 303, under the limited rotation action of the fixed block 306 and the rotating shaft 307, the guide rod 304 can be used to move the guide frame 305 to reciprocate. At this time, the guide frame 305 can drive the rotating shaft 307 on the fixed block 306 to reciprocate. The reciprocating rotation of the rotating shaft 307 can drive the sleeve 308 to automatically and stably reciprocate, and then drive the processing frame 317 to swing synchronously. At the same time, when the processing frame 317 swings to the right, under the pulling action of the traction rope 312 on the second connecting plate 311, the first conveying tube 314 can be driven to rotate automatically through the coil 313. At this time, the first conveying tube 314 can drive the limiting cylinder 318 to rotate synchronously through the limiting block 315, and then can drive the processing frame 317 on the limiting cylinder 318 to rotate synchronously; and when the processing frame 317 swings to the left, under the elastic action of the spiral spring 332 inside the limiting frame 331, the coil 314 can be driven to rotate synchronously through the first conveying tube 314. The ring 313 automatically rotates in the opposite direction, thereby automatically winding up the traction rope 312, and under the reverse rotation of the first conveying tube 314, the processing frame 317 can be driven to rotate in the opposite direction through the limit block 315 and the limit cylinder 318; in this way, the processing frame 317 can be driven to automatically and stably reciprocate during the reciprocating swing, thereby efficiently and evenly oscillating and mixing the puncture sampling specimen and the diluent in the processing frame 317, and completing the dilution work of the specimen conveniently and stably, thereby ensuring the stability of the subsequent sample separation work of the specimen; After the specimen dilution is completed, the servo motor 302 can be turned off, and the processing frame 317 can be restored to the initial state. Then the staff can open the solenoid valves 326 on each second delivery tube 325. At this time, the specimen dilution liquid in the processing frame 317 can be stably delivered to the transfer frame 328 through each second delivery tube 325. Then, the specimen dilution liquid is stably delivered to the first delivery tube 314 through the through hole 327 on the first delivery tube 314. Then, the specimen dilution liquid can be automatically delivered to the liquid storage frame 702 through the first fixed tube 4 and the connecting hose 5, and is located between the baffles 704 on both sides. Before dividing the samples, the staff can pull the first clamping rods 709 on the first fixing plates 707 on both sides of the discharge tube 706 to the side. At this time, the first clamping rods 709 can move out of the first clamping grooves 711 on both sides of the bottom of the blocking block 710, so that the blocking block 710 and the discharge tube 706 can be easily disassembled and separated, and the discharge tube 706 can be opened. Similarly, it is only necessary to pull the first clamping rods 709 on the first fixing plates 707 on both sides of the discharge tube 706 to the side in advance, and the blocking block 710 can be moved to the side. Insert it into the feed tube 706, and then release the first clamping rod 709. At this time, under the elastic action of the first return spring 708, the first clamping rod 709 can be driven to automatically engage with the first clamping groove 711 on the blocking block 710, completing the engagement and installation of the blocking block 710. The blocking block 710 can be used to conveniently and stably completely block the feed tube 706, thereby avoiding the problem that the diluent will remain in the blocked feed tube 706 during the subsequent sample separation process, resulting in specimen waste and inconvenience in subsequent cleaning; By adjusting the open state and the blocked closed state of each feed tube 706 individually, the number of sample divisions can be conveniently adjusted according to actual needs; after the number of sample divisions is adjusted, the staff can place the test tube 8 under the opened feed tube 706, and insert the test tube 8 into the cylindrical rubber airbag 714, and the bottom of the test tube 8 is inserted into the air storage frame 715 through the third positioning groove 716; then the staff can drive the hydraulic rod 701, and use the hydraulic rod 701 to push the bottom liquid storage frame 702 to move downward stably, and use The downward movement of the liquid storage frame 702 can push each test tube 8 to move downward at the same time. Under the downward movement of the test tube 8, the first rubber piston 718 in the gas storage frame 715 can be pushed to move downward. Under the downward movement of the first rubber piston 718, the corresponding rubber airbag 714 can be automatically inflated through the air guide tube 719. By using the inflated rubber airbag 714, combined with the pressing of the liquid storage frame 702, multiple test tubes 8 can be automatically and stably clamped and positioned at the same time, thereby ensuring the stability of subsequent sample separation and material feeding. After the multiple test tubes 8 are clamped and positioned, the feed tube 706 can be stably inserted into the top of the corresponding test tube 8, and then the staff can rotate the two-way threaded rods 703 on both sides of the liquid storage frame 702. The rotation of the two-way threaded rods 703 on both sides can drive the baffles 704 connected by threads on both sides to move to the side at the same time. At this time, the rubber plates 705 on the baffles 704 on both sides can move away from the feed tube 706, and the feed tube 706 loses its obstruction. Through each opened feed tube 706, the diluted specimen liquid can be simultaneously transported into the corresponding test tube 8 until the specimen liquid is transported, thereby realizing the equal amount of puncture specimens The sample division work is convenient and accurate; After the specimen sorting work is completed, the hydraulic rod 701 can be driven to drive the liquid storage frame 702 to move upward and reset. At this time, the liquid storage frame 702 moves away from each test tube 8. At this time, the test tube 8 loses the downward thrust. Therefore, under the elastic action of the first reinforcing spring 717, the first rubber piston 718 can be driven to automatically move upward and reset, and then the air inside the rubber airbag 714 can be sucked through the first rubber piston 718 and the air guide tube 719. At this time, the rubber airbag 714 returns to its original state. At this time, the test tube 8 loses the clamping force, and then the staff can take the test tube 8, ensuring the convenience of subsequent transportation of the test tube 8; After the device is finished working, the processing frame 317 and the first cover plate 320 can be disassembled and separated again to facilitate their subsequent cleaning, and clean water can be transported into the processing frame 317 to complete the cleaning of the conveying channel, thereby ensuring the convenience of repeated use of the device. Then the staff can pull the second clamping rod 11 on the second fixing plate 9 to the side again until the second clamping rod 11 moves out of the third clamping groove 21 on the connecting rod 20, and then the staff can cover the protective shell 12 on the mounting plate 1 and press it downward. At this time, under the pressing action of the protective shell 12, each connecting rod 20 can be pushed Move downward to reset, and then the staff can loosen the second clamping rod 11 on the second fixed plate 9. At this time, under the elastic action of the second reset spring 10, the second clamping rod 11 can be driven to automatically move and reset, and stably engage in the second clamping groove 13 on the protective shell 12, to ensure the stability of the engaging state of the protective shell 12 and complete the protection of the entire device. Moreover, after the connecting rod 20 moves downward to reset, it can drive the second rubber piston 19 to move downward to reset. At this time, the negative pressure inside the rubber suction cup 17 disappears, and the adsorption force on the work surface is lost, which can ensure the convenience of subsequent carrying and transportation of the entire device.
