[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. In the present invention, by fixing a chopping block on the dredging rod, it is convenient to chop and conduct tissues and blood clots inside the suction tube. Since the wound fluid contains tissues or blood clots, when the tissues or blood clots enter the interior of the suction tube and cause the interior of the suction tube to be blocked, the rotating ring is rotated relative to the circular box, and the suction tube is rotated during the rotation of the rotating ring until the end suction port of the suction tube is located directly below the dredging rod, and the dredging rod is moved downward. During the downward movement of the dredging rod, the chopping block is moved to the interior of the suction tube. Since the chopping block has a chopping blade, the tissues and blood clots inside the suction tube are chopped and conducted by the chopping block, and the chopping block is rotated inside the suction tube, thereby accelerating the chopping and conducting of the tissues and blood clots inside the suction tube.

[0040] 2. In the present invention, by setting a crushing plate, it is convenient to crush tissue matter or blood clots inside the suction port at the end of the suction tube. When the suction tube is sucking the patient's traumatic fluid, since the traumatic fluid contains tissue matter or blood clots, the suction port at the end of the suction tube is easily blocked when the tissue matter or blood clots enter the suction port at the end of the suction tube. The staff opens the fifth control valve, and the fan works to allow the gas to enter the interior of the accommodating chamber through the connected pipe, the first ventilation interval, the second ventilation interval, and the inlet pipe. As the gas inside the accommodating chamber increases, the movable plate moves. During the movement of the movable plate, the crushing plate moves through the connecting plate, thereby realizing the movement of the crushing plate to the suction port at the end of the suction tube. Since the crushing plate is a crushing blade, the tissue matter or blood clot is crushed when the crushing plate moves to the inside of the suction port at the end of the suction tube, preventing the tissue matter or blood clot from clogging the suction port at the end of the suction tube.

[0059] The dredging rod 8 is movably arranged relative to the suction tube 6, and a chopping block 9 is fixedly connected to the dredging rod 8.

[0060] The staff places the suction tube 6 near the fluid collection point for the patient's gastrointestinal surgery, and rotates the rotating ring 5 relative to the circular box 3 until one end of the suction port 7 is connected to the suction tube 6. At this time, the suction tube 6 is in a vertical state, that is, the bottom of the suction tube 6 is located at the fluid collection point for the patient's gastrointestinal surgery. The suction machine 1 works to allow the trauma fluid to pass through the suction tube 6 and the fluid flow tube 54 into the interior of the collection box 2, and the trauma fluid is collected by the collection box 2.

[0061] Since the trauma fluid contains tissue matter or blood clots, when tissue matter or blood clots enter the interior of the suction tube 6 and cause blockage of the suction tube 6, the rotating ring 5 is rotated relative to the circular box 3, and the suction tube 6 is rotated during the rotation of the rotating ring 5 until the end suction port of the suction tube 6 is located directly below the dredging rod 8, and the dredging rod 8 is moved downward. During the downward movement of the dredging rod 8, the chopping block 9 is moved to the interior of the suction tube 6. Since the chopping block 9 has a chopping blade, the tissue matter and blood clots inside the suction tube 6 are chopped and connected by the chopping block 9, and the chopping block 9 is rotated inside the suction tube 6, thereby accelerating the chopping and connecting of the tissue matter and blood clots inside the suction tube 6.

[0094] When the suction tube 6 is sucking the patient's trauma fluid, since the trauma fluid contains tissue matter or blood clots, the tissue matter or blood clots entering the end suction port of the suction tube 6 may easily cause blockage. The staff opens the fifth control valve 48, and the fan 33 works to allow the gas to enter the interior of the accommodating chamber 37 through the connecting tube 47, the first ventilation interval 46, the second ventilation interval 60, and the inlet tube 44. As the gas inside the accommodating chamber 37 increases, the movable plate 38 moves. During the movement of the movable plate 38, the crushing plate 40 moves through the connecting plate 39, thereby moving the crushing plate 40 to the end suction port of the suction tube 6. Since the crushing plate 40 is a crushing blade, the crushing plate 40 crushes the tissue matter or blood clot when it moves to the end suction port of the suction tube 6 to prevent the tissue matter or blood clot from clogging the end suction port of the suction tube 6.

[0095] The suction machine 1 is connected with a fixed pipe 49 , and the collection box 2 is connected with a movable pipe 50 . One end of the movable pipe 50 is sealed and movably connected to the inside of the horizontal section of the fixed pipe 49 , so as to realize the movement of the collection box 2 relative to the suction machine 1 .

When the wound fluid collected in the collecting box 2 needs to be discharged, the staff will remove the blocking block 52, thereby facilitating the discharge of the wound fluid collected in the collecting box 2 through the bottom opening.

[0099] Working principle: the staff turns the locking bolt 16 to disengage the locking bolt 16 from the fixed plate 12 and the slide plate 14, that is, the locking bolt 16 does not lock the slide plate 14 inside the slide groove 13 of the fixed plate 12. The staff manually adjusts the position of the slide plate 14, and the suction tube 6 moves during the movement of the slide plate 14, thereby adjusting the position of the suction tube 6. The staff turns the locking bolt 16, and the slide plate 14 is locked on the fixed plate 12 through the cooperation of the locking bolt 16 and the bolt hole.

[0100] The first driving motor 17 works to realize the rotation of the driving rod 18, and the rotating ring 5 rotates during the rotation of the driving rod 18 until one end of the suction port 7 is connected with the suction tube 6, and until the suction port at the end of the suction tube 6 is located at the patient's liquid collection location. The suction machine 1 works to realize the trauma fluid passing through the suction tube 6 and the liquid flow tube 54 into the interior of the collecting box 2, and the trauma fluid is collected by the collecting box 2.

[0101] When the suction tube 6 is sucking the patient's trauma fluid, since the trauma fluid contains tissue matter or blood clots, the tissue matter or blood clots entering the end suction port of the suction tube 6 may easily cause blockage. The staff opens the fifth control valve 48, and the fan 33 works to allow the gas to enter the interior of the accommodating chamber 37 through the connecting tube 47, the first ventilation interval 46, the second ventilation interval 60, and the inlet tube 44. As the gas inside the accommodating chamber 37 increases, the movable plate 38 moves. During the movement of the movable plate 38, the crushing plate 40 moves through the connecting plate 39, thereby moving the crushing plate 40 to the end suction port of the suction tube 6. Since the crushing plate 40 is a crushing blade, the crushing plate 40 crushes the tissue matter or blood clot when it moves to the end suction port of the suction tube 6 to prevent the tissue matter or blood clot from clogging the end suction port of the suction tube 6.

[0102] When the upper suction tube 6 is blocked by tissue or blood clot, the second control valve 27 is closed, and gas is injected into the cavity 20 through the connecting tube 24. As the gas in the cavity 20 increases, the movable block 21 is moved by the gas pressure in the cavity 20, and the first spring 23 is in a stretched state during the movement of the movable block 21. The baffle 19 moves during the movement of the baffle 19, and the connecting hole 22 is connected to the suction port 7 during the movement of the baffle 19. When the chopping block 9 chops and unclogs the tissue or blood clot in the upper suction tube 6, the suction machine 1 works to enable the chopped tissue or blood clot in the upper suction tube 6 to enter the interior of the collecting box 2 through the liquid flow tube 54, thereby unblocking the upper suction tube 6.

[0103] Since the wound fluid contains tissue or blood clots, when the tissue or blood clots enter the interior of the suction tube 6 and cause the interior of the suction tube 6 to be blocked, the rotating ring 5 is rotated relative to the circular box 3, and the suction tube 6 is rotated during the rotation of the rotating ring 5 until the end suction port of the suction tube 6 is located directly below the dredging rod 8, so that the dredging rod 8 moves downward, and during the downward movement of the dredging rod 8, the chopping block 9 is moved to the interior of the suction tube 6. Since the chopping block 9 has a chopping blade, the tissue and blood clots inside the suction tube 6 are chopped and conducted by the chopping block 9. When the chopping block 9 is located in the interior of the upper suction tube 6 and the tissue or blood clots inside the upper suction tube 6 need to be chopped by the chopping block 9, air is injected into the interior of the moving box 31 through the air inlet 58, and the fan blades 32 are rotated due to the action of wind force, and the dredging rod 8 is rotated during the rotation of the fan blades 32. The chopping block 9 is rotated during the rotation of the dredging rod 8, thereby facilitating the chopping of the tissue or blood clots inside the upper suction tube 6.

[0104] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
