Specific implementation mode

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0026] Please refer to Figures 1 to 6 , the present invention provides a technical solution: an integrated negative pressure suction specimen shunting device, including a collection bucket 1, a liquid injection pipe 2 and a liquid discharge pipe 3 are respectively fixedly installed on the side of the collection bucket 1, a connection seat 4 is fixed on the top of the collection bucket 1, a support seat 6 is rotatably installed on the connection seat 4, a pressure application seat 7 is fixed at one end of the support seat 6, an air extraction pipe 9 and an air inlet pipe 10 are respectively fixedly installed at both ends of the pressure application seat 7, ring seats 12 are movably installed at one ends of the air extraction pipe 9 and the air inlet pipe 10, limit rings 11 are fixed on the air extraction pipe 9 and the air inlet pipe 10, a sealing seat 8 is movably installed on the top of the pressure application seat 7, a connection pipe 20 is fixed on the top of the pressure application seat 7, the sealing seat 8 is rotatably installed on the connection pipe 20, and the sealing seat 8 and the connection pipe 20 cooperate to package the sealing performance of the pressure application seat 7. Later, the sealing seat 8 is rotated and disassembled from the connection pipe 20. After disassembly, the movable seat 17 is driven by the fixed column 14 to be taken out upward.

[0027] In this embodiment, a threaded seat 13 is fixed on the connection seat 4, internal threads are opened on the inner wall of the support seat 6, and the support seat 6 is rotatably installed inside the threaded seat 13 through the internal threads. A cavity 16 is opened inside the collection bucket 1, a movable seat 17 is movably installed inside the cavity 16, a conical seat 18 is fixed inside the movable seat 17, a collection seat 19 is fixed at one end of the conical seat 18, filter holes are opened on both the collection seat 19 and the conical seat 18, and the diameter of the filter holes on the collection seat 19 is smaller than the diameter of the filter holes on the conical seat 18. A fixed column 14 is fixed on the top of the movable seat 17, and one end of the fixed column 14 is movably installed on the inner wall of the sealing seat 8. The conical seat 18 and the collection seat 19 cooperate to facilitate the rapid downward sliding of the specimen. After the specimen enters the collection seat 19, it is convenient to contact the specimen with the liquid inside the cavity 16 for short-term storage.

[0028] In this embodiment, a movable disk 23 is movably installed inside the pressure seat 7. An arc-shaped groove 25 is formed on one side of the movable disk 23, and a filter plate 33 is fixedly installed on the arc-shaped groove 25. The movable disk 23 is installed inside the pressure seat 7 through a torsion spring shaft. A baffle 21 and a limiting plate 24 are respectively and fixedly installed on the inner wall of the pressure seat 7. The baffle 21 and the limiting plate 24 are in movable contact with the movable disk 23. An opening 22 is formed on the baffle 21. The torsion spring shaft includes a rotating tube 34. A rotating column 35 is movably installed inside the rotating tube 34. One end of the rotating column 35 is fixed on the inner wall of the pressure seat 7. A torsion spring 36 is fixed between the rotating column 35 and the rotating tube 34. The movable disk 23 always inclines to one side through the torsion spring shaft. After the movable disk 23 inclines, the baffle 21 and the limiting plate 24 perform limit support for the movable disk 23.

[0029] In this embodiment, a cleaning ring 31 is movably installed inside both the air extraction pipe 9 and the air inlet pipe 10. A fixed pipe 32 is fixed on one side of the cleaning ring 31. One end of the fixed pipe 32 is fixed on the ring seat 12. Ring grooves 28 are formed inside both the air extraction pipe 9 and the air inlet pipe 10. A tension mechanism 29 is fixed inside the ring groove 28. One end of the tension mechanism 29 is fixed with a movable column 30. One end of the movable column 30 is fixed on the ring seat 12. Air pipes 26 are movably installed on both the air extraction pipe 9 and the air inlet pipe 10. A support pipe 27 is fixed on the air pipe 26. A fixed ring is fixed on the inner wall of the support pipe 27. The fixed ring cooperates with the limiting ring 11. The ring seat 12 is in movable contact with one end of the air pipe 26. The tension mechanism 29 is a tension spring. The tension spring drives the ring seat 12 to move towards the pressure seat 7. However, after the air pipe 26 squeezes the ring seat 12 later, the reaction force generated by the tension mechanism 29 pushes the air pipe 26 to move outwards. The outward movement of the air pipe 26 realizes the limit fixation of the support pipe 27.

[0030] When the device is in use, first install the air extraction pipe 9 and the air inlet pipe 10 between the air pipes 26 of the negative pressure device. When installing the air pipe 26, when the support pipe 27 on the air pipe 26 is installed on the air extraction pipe 9, by squeezing the support pipe 27, the fixing rings on the support pipe 27 are respectively installed on the air extraction pipe 9 and the air inlet pipe 10 through the limit rings 11. One end of the air pipe 26 squeezes the ring seat 12, and the ring seat 12 squeezes the tension mechanism 29 through the movable column 30. The reaction force generated by the tension mechanism 29 pushes the ring seat 12 to move outward. The outward movement of the ring seat 12 pushes the air pipe 26 to move. The movement of the air pipe 26 makes the fixing ring at the support pipe 27 always contact the limit ring 11 for limit fixation. At the same time, the contact between the fixing ring and the limit ring 11 seals the support pipe 27, which is convenient for the rapid installation of the air pipe 26 in the early stage. After the air pipe 26 is installed, it attracts and collects the sample. The sample enters the inside of the pressurizing seat 7 through the air inlet pipe 10, and the gas flows through the filter plate 33 and the opening 22. When the impurities carried in the gas pass through the filter plate 33, they are filtered and adsorbed. The larger samples fall into the movable seat 17 inside the collection bucket 1. The diameter of the filter holes on the collection seat 19 is smaller than the diameter of the filter holes on the conical seat 18. The sample slides onto the collection seat 19 on the conical seat 18 for collection. Before collection, inject liquid into the inside of the collection bucket 1 through the liquid injection pipe 2. The contact between the liquid and the sample increases the preservation time of the sample. When it is necessary to take out the sample, inject liquid through the liquid injection pipe 2 and drain water through the drain pipe 3. The injection of liquid through the liquid injection pipe 2 makes the collection bucket 1 generate a rotational centrifugal force. The rotational centrifugal force of the liquid drives the objects inside the conical seat 18 and the collection seat 19 to rotate and wash, washing the tissues and blood clots inside the conical seat 18 and the collection seat 19. After washing, then take out the conical seat 18 and the collection seat 19 upward. When the device is not disassembled, the sealing seat 8 rotates and separates from the connecting pipe 20. After separation, the fixed column 14 drives the movable seat 17 to move upward. The movable seat 17 moves to the movable disk 23. The side of the movable seat 17 enters the inside of the arc-shaped groove 25. The movable seat 17 moves inside the arc-shaped groove 25 and scrapes one side of the filter plate 33. The scraping removes the substances adsorbed on the filter plate 33. The conical seat 18 and the collection seat 19 are in a conical state, which can effectively prevent the sample from falling from the side during the up and down movement. When not in use in the later stage, the air pipe 26 is removed from the air extraction pipe 9 and the air inlet pipe 10. After removal, the ring seat 12 moves outward. The ring seat 12 drives the cleaning ring 31 to move inside the air extraction pipe 9 and the air inlet pipe 10 through the fixed pipe 32. When the cleaning ring 31 moves, it scrapes the impurities remaining on the inner wall of the interface outward, which is convenient for the later cleaning and disinfection of the pressurizing seat 7.
