[0022] Example 1, as Figure 1-3 As shown, the pulse flushing drainage device assembly includes a device body 1, with an infusion tube 4 and a power cord 5 at the bottom of the device body 1. A piston pump is installed inside the device body 1, and a control button for controlling the start and stop of the piston pump is installed on the outer surface of the device body 1. An extension device 2 is installed at one end of the device body 1 to improve the drainage device's effectiveness.
[0023] Reference Figure 1-7As shown, in this embodiment: the expansion device 2 includes a docking ring 22, a groove block 23 is fixedly connected to one side of the docking ring 22, a shower head and a long pipe nozzle are provided on one side of the outer surface of the groove block 23, two through holes 24 are opened on the outer surface of the groove block 23, a first sprocket 25 is rotatably connected to the inner wall of the groove block 23, a liquid passage hole 26 is opened on the outer surface of the first sprocket 25, a second sprocket 27 is rotatably connected to the top of the outer surface of the groove block 23, a chain 28 is sleeved on the outer surface of the first sprocket 25 and the second sprocket 27, the chain 28 moves on the top of the inner wall of the groove block 23, a round block 29 is fixedly connected to one side of the second sprocket 27, a slot 210 is opened on one side of the round block 29, and two rotating shafts 211 are rotatably connected to the top of the device body 1. A rectangular rod 213 is fixedly connected to the surface. A coil spring 212 is provided at the bottom end of the rotating shaft 211. The two ends of the coil spring 212 are fixedly connected to one side of the rotating shaft 211 and the inner wall of the device 1, respectively. A circular groove 21 is opened at one end of the device 1. One end of the infusion tube 4 is connected to the inside of the circular groove 21. When using the drainage device assembly, the expansion device 2 is installed at one end of the device 1 with the help of the convenient device 3. Then, one end of the infusion tube 4 is connected to the saline bag and the negative pressure suction device, respectively. Then, the power cord 5 is connected to the power supply. Press one side of the rectangular rod 213 at the top of the device 1 to push the rectangular rod 213 and control the rectangular rod 213 to rotate away from the circular block 29 through the rotating shaft 211, so that the rectangular rod 213 disengages from the slot 210 on the outer surface of the circular block 29. Then push The rotating circular block 29 drives the second sprocket 27 to rotate, which in turn drives the first sprocket 25 to rotate via the chain 28. The first sprocket 25 rotates at the same angle as the second sprocket 27 and the circular block 29. When the slot 210 on the outer surface of the rotating block 29 aligns with the position of a rectangular rod 213, releasing the coil spring 212 of the rectangular rod 213 and restoring it to its original state will cause the rectangular rod 213 and the rotating shaft 211 to rotate towards the circular block 29, causing the rectangular rod 213 to engage with the slot 210 and restricting the angle of the circular block 29. The position of the slot 210 on the outer surface of the circular block 29 corresponds to the position of the liquid passage hole 26. Similarly, the corresponding liquid can pass through the shower head or long pipe nozzle on the outside of the tank block 23. When using the drainer, press the outer surface of the drainer. The piston pump inside the controller body 1 operates to generate pulsed water flow, which enters the docking ring 22, passes through a through hole 24 on the outer surface of the slot block 23, passes through the liquid passage hole 26, and exits at the corresponding nozzle. During surgery, if the nozzle needs to be changed, the circular block 29 is rotated so that the slot 210 on the outer surface of the circular block 29 is positioned on the corresponding side of the shower head or long pipe nozzle. By setting the expansion device 2 and using the convenient device 3, the slot block 23 is installed at one end of the body 1. When using the drainage device, the position of the slot 210 on the outer surface of the circular block 29 is adjusted to change the position of the liquid passage hole 26 on the outer surface of the first sprocket 25. Correspondingly, the shower head or long pipe nozzle on one side of the slot block 23 is connected to the liquid passage hole 26 on the outer surface of the first sprocket 25.This design allows for quick changes to the required nozzle assembly during surgery, eliminating the need for complete disassembly and reinstallation of the entire nozzle. This significantly improves the flexibility and practicality of using the drainage device assembly and reduces the risk of infection associated with nozzle changes.
[0024] Reference Figure 2-7 As shown in this embodiment: one end of the rectangular rod 213 is fixedly connected to a protrusion 214. The outer surface of the protrusion 214 is arc-shaped. When the rotating shaft 211 is controlled to rotate, pressing the arc-shaped protrusion 214 at one end of the two rectangular rods 213 can more easily pinch the rectangular rods 213 to control the rectangular rods 213 to rotate through the rotating shaft 211. Several protrusions 215 are fixedly connected to the outer surface of the circular block 29. The protrusions 215 are distributed circumferentially on the outer surface of the circular block 29. By pressing the protrusions 215 on the outer surface of the circular block 29 with your hand, you can more easily push the circular block 29 to rotate and it is not easy to slip.
[0025] Reference Figure 2-7 As shown in this embodiment: a support ring 216 is fixedly connected to one side of the top of the groove block 23, and the outer surface of the round block 29 rotates on the inner wall of the support ring 216. By setting the support ring 216, the round block 29 can be supported and reinforced at the top of the groove block 23, thereby improving the stability of the expansion device 2 when it is used after installation.
[0026] Reference Figure 1-5As shown in this embodiment: the convenient device 3 includes two L-shaped rods 31. One end of the L-shaped rod 31 is fixedly connected to one side of the device body 1. A round rod 32 is slidably connected to one end of the inner wall of the L-shaped rod 31. A plug block 33 is fixedly connected to one end of the round rod 32. The plug block 33 slides on the inner wall of the device body 1. A spring 34 is provided at one end of the plug block 33. The two ends of the spring 34 are fixedly connected to one side of the plug block 33 and the end of the L-shaped rod 31 away from the device body 1, respectively. Slots 35 are provided on both sides of the docking ring 22. When installing the extension device 2, the positions of the two slots 35 on the outer surface of the docking ring 22 are aligned with the positions of the two plug blocks 33 at one end of the device body 1, and the slots 210 on the outer surface of the round block 29 are aligned with the position of a rectangular rod 213. The docking ring 22 is inserted into the round groove 21 at one end of the device body 1. During the insertion process, the two round rods 32 are pulled to move away from the device body 1 and the spring 34 is compressed. After one end of the docking ring 22 is pressed against one end of the inner wall of the circular groove 21, releasing the round rod 32 and restoring the spring 34 to its original state will push the insert block 33 to move towards the docking ring 22. Insert one end of the insert block 33 into the slot 35 on the outer surface of the docking ring 22 to fix the position of the docking ring 22 inside the circular groove 21, thus completing the installation of the expansion device 2. Pulling the two round rods 32 controls the insert block 33 to move away from the docking ring 22. Then, pulling the groove block 23 and the docking ring 22 outwards will remove the expansion device 2. This allows for selection based on needs, such as whether to install the expansion device 2 or directly install the nozzle for use. One end of the round rod 32 is fixedly connected to an auxiliary rod 36, which is a semi-circular hook-shaped rod. Hooking the auxiliary rod 36 at one end of the two round rods 32 makes it easier to pull the round rods 32 to control the movement of the round rods 32 and the insert block 33, improving the convenience of installing and removing the expansion device 2.
[0027] Working principle: When using the drainage device assembly, align the two slots 35 on the outer surface of the docking ring 22 with the two inserts 33 at one end of the device body 1, and align the groove 210 on the outer surface of the circular block 29 with a rectangular rod 213. Insert the docking ring 22 into the circular groove 21 at one end of the device body 1. During insertion, pull the two circular rods 32 away from the device body 1 and compress the spring 34. After one end of the docking ring 22 abuts against the inner wall of the circular groove 21, release the circular rods 32 and the spring 34 will return to its original state, pushing the inserts 33 towards the docking ring 22. Insert one end of the inserts 33 into the docking ring 22. Inside the slot 35 on the outer surface of the device 2, fix the docking ring 22 in the position inside the circular groove 21. Install the expansion device 2 at one end of the device body 1. Then connect one end of the infusion tube 4 to the saline bag and the negative pressure suction device respectively. Then connect the power cord 5 to the power supply. Press one side of the rectangular rod 213 on the top side of the device body 1 to push the rectangular rod 213 and control the rectangular rod 213 to rotate away from the circular block 29 through the rotating shaft 211, so that the rectangular rod 213 disengages from the slot 210 on the outer surface of the circular block 29. Then push the circular block 29 to rotate, which drives the second sprocket 27 to rotate through the chain 2. The transmission 8 drives the first sprocket 25 to rotate. The first sprocket 25 rotates at the same angle as the second sprocket 27 and the circular block 29. When the position of the groove 210 on the outer surface of the circular block 29 aligns with the position of a rectangular rod 213, releasing the coil spring 212 of the rectangular rod 213 and restoring it to its original state will cause the rectangular rod 213 and the rotating shaft 211 to rotate towards the circular block 29, so that the rectangular rod 213 is inserted into the groove 210, thus limiting the angle of the circular block 29. The position of the groove 210 on the outer surface of the circular block 29 corresponds to the position of the liquid passage hole 26. Similarly, the corresponding liquid can pass through the shower head or long pipe outside the tank block 23. When using the drainage device, press the control button on the outer surface of the drainage device. The piston pump inside the controller body 1 will operate to generate a pulsed water flow into the docking ring 22. The water flows through a through hole 24 on the outer surface of the groove block 23, through the liquid passage hole 26, and into the nozzle corresponding to the liquid passage hole 26. If it is necessary to change the nozzle used during the operation, rotate the round block 29 so that the slot 210 on the outer surface of the round block 29 is located on the corresponding side of the shower head or long pipe nozzle. Pull the two round rods 32 to control the insertion block 33 to move away from the docking ring 22. Then pull the groove block 23 and the docking ring 22 outward to remove the expansion device 2.
