[0020] In this embodiment: After surgery, the existing abdominal surgery in the market usually uses a drainage tube plus a drainage bag to guide the accumulated fluid in the abdominal cavity into the drainage bag through the drainage tube, so as to discharge the accumulated fluid from the body, and the doctor can judge the patient's recovery by observing the color of the liquid in the drainage bag. However, since the drainage bag is usually vacuumed after leaving the factory for easy storage and stacking, after the drainage tube is inserted into the patient's abdominal cavity, the inner walls of the bag are tightly attached to each other because the drainage bag is in a deflated state, which makes it difficult for the accumulated fluid to enter the bag through the drainage tube, and the flow is hindered; In order to avoid the above situation, in the process of using the device, firstly, the end of the drainage tube 20 is inserted into the hole reserved for the patient after surgery, and then the position of the end of the drainage tube 20 is fixed with medical tape, and then the cavity fluid drainage bag 19 is placed in the outer frame body 1, so that the lower end of the cavity fluid drainage bag 19 is placed on the upper surface of the first resistance block 34, so that the drainage tube 20 is between the two rubber blocks 18, and then the cylinders 2 on the left and right sides are started at the same time. After the cylinder 2 is started, the first transmission gear 3 at the output end is moved closer to each other, and as the first transmission gear 3 moves, the first suction cup 22 is moved synchronously, and the first suction cups 22 on both sides are moved closer to each other, squeezing the shriveled cavity fluid drainage bag 19 in the middle. At this time, as the first suction cups 22 on both sides are close to each other, the When the first suction cup 22 is close to the first fixing frame 4, the second transverse tubes 27 on both sides collide with each other, causing the second transverse tube 27 to slide with the piston 28 along the inner wall of the first transverse tube 21 in the direction away from the first suction cup 22 after being subjected to force, and as the first suction cups 22 on both sides approach each other, the first suction cups 22 gradually press each other and deform, causing part of the air in the first suction cup 22 to be discharged around, and at this time, as the piston 28 continues to move along the inner wall of the first fixing frame 4, the space between the piston 28 and the end of the first fixing frame 4 gradually increases, so the negative pressure also gradually increases, causing the remaining air in the first suction cup 22 to be sucked into the space between the piston 28 and the end of the first fixing frame 4 through the second transverse tube 27 and the air outlet 29, causing the first suction cups 22 on both sides to be tightly adsorbed on the surface of the cavity fluid drainage bag 19; And as the piston 28 moves, the pressure plate 301 is also moved synchronously. When the pressure plate 301 moves, it moves together with the second ball 31 arranged to rotate on the outer wall. The second ball 31 is slidably connected with the inner wall of the spiral groove 32. During the movement of the second ball 31, the spiral groove 32 will be subjected to force. Since the first fixed frame 4 is guided and restricted by the third guide rod 80 when it moves, the first fixed frame 4 cannot rotate. At this time, the first transmission gear 3 will rotate with the force of the spiral groove 32. When the first transmission gear 3 rotates, it drives the second transmission gear 5 to rotate through meshing. When the second transmission gear 5 rotates, it drives the first guide rod 12 of the outer wall to move in a circle. During the movement of the first guide rod 12, the first ball 13 at its end will slide along the annular track groove 15. Since a plurality of arc-shaped protrusions 16 are provided in the annular track groove 15, when the first ball 13 slides through the arc-shaped protrusion 16, it will produce an impact on the second fixed block 14 The resistance force causes the second fixed block 14 to bear force with the third fixed block 17. The third fixed blocks 17 on both sides compress the second return spring 25 along the second slide groove 24 so as to approach each other. At this time, the second fixed blocks 14 on both sides approach each other, and the rubber blocks 18 on both sides approach each other to press the drainage tube 20 therebetween. The rubber block 18 is a soft and deformable rubber block, which can still deform a certain distance after being squeezed against each other. When the first ball 13 and the first guide rod 12 slide through the arc-shaped protrusion 16, the second return spring 25 rebounds and brings the third fixed block 17 and the second fixed block 14 to reset. When passing through multiple arc-shaped protrusions 16, the rubber block 18 is caused to reciprocately press the drainage tube 20. Pressing the drainage tube 20 causes the accumulated fluid at the pressed part to be squeezed into the cavity fluid drainage bag 19 by external force, so that the accumulated fluid in the drainage tube 20 can pass quickly, preventing the accumulation of impurities such as sediment or thrombus in the accumulated fluid from accumulating in the drainage tube 20 and causing blockage. When the first guide rod 12 and the first ball 13 pass through the sinking groove 151, the first guide rod 12 will press the inner wall of the annular track groove 15 downward, causing the second fixed block 14 to be forced downward as a whole, and the second fixed block 14 will be forced downward with the sliding sleeve rod 11, and the sliding sleeve rod 11 will be forced downward with the sliding inner plate 9, and the sliding inner plate 9 will compress the first return spring 10 downward along the outer wall of the first guide rod 8, and slide down along the inner wall of the first slide groove 7, causing the second fixed block 14 to move down a distance, and when the first guide rod 12 and the first ball 13 continue to slide into the annular track groove 15 through the sinking groove 151, at this time, the second fixed block 14 will follow and move up and reset, so the second fixed block 14 will move down at a certain interval, and then rise and reset, so the rubber block 18 on the outer wall of the second fixed block 14 can squeeze and drive out bubbles for a longer distance of the drainage tube 20 close to the cavity fluid drainage bag 19, so as to assist the accumulated fluid to enter the cavity fluid drainage bag 19 more smoothly; As the piston 28 continuously moves in the direction away from the first suction cup 22, the piston 28 moves synchronously with the pressure plate 301, and the pressure plate 301 and the second suction cup 331 are finally adsorbed on the inner wall of the first transmission gear 3 due to extrusion, thereby limiting the reset of the third reset spring. At this time, the cylinder 2 is started in the reverse direction, causing the output end of the cylinder 2 to move in the reverse direction. At this time, the first suction cups 22 on both sides will pull the outer walls of the cavity fluid drainage bag 19 on both sides in opposite directions, causing the inner walls of the cavity fluid drainage bag 19 that are tightly attached on both sides to separate, and during the separation process, the space in the cavity fluid drainage bag 19 continues to increase, and the negative pressure in the cavity fluid drainage bag 19 will also increase accordingly. The negative pressure in the cavity fluid drainage bag 19 can help the accumulated fluid in the drainage tube 20 to enter the cavity fluid drainage bag 19 more smoothly; When there is no need to pull the outer wall of the cavity fluid drainage bag 19 any more, the first suction cup 22 is lifted by hand to adsorb the surface of the cavity fluid drainage bag 19, and then the second transverse tube 27 is pulled outward to move the second suction cup 331 until the adsorption to the inner wall of the first transmission gear 3 is released. At this time, the third return spring 30 is reset to move the piston 28, and the piston 28 moves the pressing plate 301 toward the first suction cup 22, so that the pressing plate 301 and the second ball 31 on the outer wall slide along the inner wall of the spiral groove 32, so that the first transmission gear 3 rotates in the opposite direction, and the first transmission gear 3 rotates in the opposite direction to engage the second transmission gear 5 to rotate, that is, at this time, the rubber blocks 18 on both sides can press the drainage tube 20 back and forth for a period of time, so that the accumulated fluid flows into the cavity fluid drainage bag 19 more smoothly. And in the above operation process, in the initial stage of drainage of effusion, the first suction cup 22 pulls the outer wall of the cavity fluid drainage bag 19, which is not enough to affect the lower end part of the cavity fluid drainage bag 19, so the effusion is easily deposited in the middle part of the cavity fluid drainage bag 19 that has been stretched. In order to make the effusion flow more smoothly and increase the negative pressure in the cavity fluid drainage bag 19, the second guide rod 38 will rotate with the circular axis during the rotation of the first transmission gear 3. During the circumferential movement of the second guide rod 38, the first arc surface 39 of the end portion will contact the second arc surface 41 of the end portion of the third guide rod 40, so that the third guide rod 40 is forced to slide toward the inner wall of the second fixed frame 33. During the movement of the third guide rod 40 with the second contact block 42, the fourth fixed block 23 is caused to contact The second resistance inclined surface 44 on the outer wall of the first resistance block 34 causes the first resistance block 34 to be forced upward and move upward along the second guide rod 35. When the second guide rod 38 moves past the third guide rod 40, the fourth return spring 36 returns to its original position and moves the first resistance block 34 downward. In this way, when the second guide rod 38 moves in a circle past multiple third guide rods 40, the first resistance block 34 is caused to reciprocate up and down. The up and down reciprocating movement of the first resistance block 34 will continuously push the lower end of the cavity fluid drainage bag 19 up and down, causing the accumulated fluid deposited in the middle position of the cavity fluid drainage bag 19 to flow left and right toward the lower end of the cavity fluid drainage bag 19 due to gravity, causing the inner wall to which the lower end of the cavity fluid drainage bag 19 is tightly attached to be supported and separated, so that the accumulated fluid can flow into the cavity fluid drainage bag 19 more smoothly.
