DETAILED DESCRIPTION Embodiment 1

[0035] like Figure 1 - Figure 2 As shown, a drainage and flushing device for patients with pancreatitis includes a negative pressure filtering mechanism 3 connected with a flushing tube 1 and a drainage tube 2, the negative pressure filtering mechanism 3 includes a collecting top plate 5, a driving mechanism 6 and a negative pressure mechanism 7, the driving mechanism 6 is connected with the flushing tube 1, the negative pressure mechanism 7 is connected with the drainage tube 2, the negative pressure mechanism 7 is arranged on the top of the driving mechanism 6, the collecting top plate 5 is arranged on the top of the negative pressure mechanism 7, the driving mechanism 6 drives the driving mechanism 6 through the liquid flow in the flushing tube 1 to form a negative pressure for negative pressure drainage of the drainage tube 2.

[0036] Furthermore, one end of the flushing tube 1 is connected to a driving pump for pumping liquid into the flushing tube 1 , and one end of the drainage tube 2 is connected to a drainage bottle 4 for collecting drainage fluid.

[0037] When in use, place the flushing tube 1 and the drainage tube 2 on the same side of the affected area, and the flushing tube 1 flushes the affected area by injecting liquid flow. While the liquid flow is injected into the flushing tube 1, the liquid flow will drive the negative pressure mechanism 7 through the driving mechanism 6 to form a micro-negative pressure, and the drainage tube 2 is connected to the negative pressure mechanism 7. The drainage tube 2 can perform negative pressure drainage on the affected area, thereby improving the flushing and drainage effects of the device. No additional negative pressure source is required, the structure is streamlined, and a filtering structure is provided inside the negative pressure mechanism 7 to filter the negative pressure drainage fluid.

[0038] like Figure 1 - Figure 3 As shown, the driving mechanism 6 includes a driving cavity 8, a rotating impeller 9, a driving mechanism body 10 and a driving shaft 11. The driving mechanism body 10 is fixedly connected to the bottom of the negative pressure mechanism 7, the flushing pipe 1 is connected to the driving mechanism body 10, the rotating impeller 9 is rotatably arranged in the middle of the driving cavity 8, the driving shaft 11 is fixedly connected to the middle of the rotating impeller 9, the driving cavity 8 is opened inside the driving mechanism body 10, and the flushing pipe 1 is tangent to the edge of the rotating impeller 9.

[0039] Furthermore, the angle of the impeller 9 can be tilted accordingly according to the direction of water flow in the flushing pipe 1, thereby reducing the volume of the impeller 9 while improving the driving effect of the impeller 9.

[0040] When in use, flushing liquid is injected into the flushing tube 1 . The flushing liquid impacts the rotating impeller 9 through the liquid during injection, thereby driving the rotating impeller 9 to drive the driving shaft 11 to rotate, thereby driving the negative pressure mechanism 7 through the driving shaft 11 .

[0041] like Figure 1 - Figure 4As shown, the negative pressure mechanism 7 includes a negative pressure mechanism body 12, a filter plate 13, a variable rotary vane 14, a negative pressure chamber 15 and an adaptive sleeve 16. The negative pressure mechanism body 12 is fixedly connected to the top of the driving mechanism 6, the negative pressure chamber 15 is opened inside the negative pressure mechanism body 12, the adaptive sleeve 16 is eccentrically arranged inside the negative pressure chamber 15, the driving shaft 11 is drivingly connected to the adaptive sleeve 16, the variable rotary vane 14 is symmetrically arranged at the side end of the adaptive sleeve 16, and the end of the variable rotary vane 14 away from the adaptive sleeve 16 is in contact with the inner wall of the negative pressure chamber 15, the filter plate 13 is fixedly connected between the variable rotary vanes 14, and the drainage tube 2 is connected to the negative pressure chamber 15.

[0042] Furthermore, the filter plate 13 is in an arc shape that matches the inner wall of the negative pressure chamber 15 , and the drainage tube 2 is connected to the negative pressure chamber 15 at a side that is closer to the adaptive sleeve 16 .

[0043] When in use, the driving shaft 11 drives the adaptive sleeve 16 to rotate under the drive of the rotating impeller 9, and the adaptive sleeve 16 drives the variable rotor 14 to rotate in the negative pressure chamber 15 as it rotates. Since the adaptive sleeve 16 is eccentrically arranged inside the negative pressure chamber 15, and the variable rotor 14 divides the negative pressure chamber 15, as the variable rotor 14 rotates, the liquid at one end of the negative pressure chamber 15 can be actively transported to the other end, thereby realizing negative pressure drainage of the drainage tube 2. By driving the driving shaft 11, the drainage tube 2 can also perform negative pressure drainage synchronously while the device is flushing, thereby simplifying the device structure and improving the cleaning and drainage effect.

[0044] like Figure 1 - Figure 5 As shown, the variable vane 14 includes a first vane seat 17, a sealed vane 19 and a second vane seat 20, the second vane seat 20 is fixedly connected to both ends of the filter plate 13, the filter plate 13 is slidably connected to the inside of the negative pressure chamber 15, the sealed vane 19 is fixedly connected to the inside of the second vane seat 20, the end of the sealed vane 19 facing away from the second vane seat 20 is slidably connected to the inside of the first vane seat 17, and the first vane seat 17 is fixedly connected to the side end surface of the adaptive sleeve 16.

[0045] Furthermore, the filter plate 13 moves in a circular motion inside the negative pressure chamber 15 , the first vane seat 17 is provided with a vane groove 22 adapted to the sealed vane 19 , and the first vane seat 17 , the sealed vane 19 and the second vane seat 20 are all in contact with the inner wall of the negative pressure chamber 15 .

[0046] When in use, by providing the first rotary vane seat 17, the sealed rotary vane 19 and the second rotary vane seat 20, the variable rotary vane 14 divides the adaptive sleeve 16 into two cavities. As the adaptive sleeve 16 rotates, the volumes of the two groups of cavities change, thereby realizing negative pressure drainage of the drainage tube 2. The variable rotary vane 14 will also drive the filter plate 13 to rotate in the internal loop of the negative pressure chamber 15 while rotating, so that the drainage fluid in the drainage tube 2 can be filtered through the rotating setting of the filter plate 13. At the same time, the rotating setting of the filter plate 13 can effectively avoid the situation where the drainage tube 2 is blocked and affects the drainage effect.

[0047] like Figure 1 - Figure 6 and Figure 8-Figure 9 As shown, a cleaning gap 18 is provided between the filter plate 13 and the inner wall of the negative pressure chamber 15, a scraper 32 is slidably connected in the cleaning gap 18, the scraper 32 is fitted with the outer surface of the filter plate 13, a slider 31 is provided in the middle of the scraper 32, and an arc-shaped slide groove 30 adapted to the slider 31 is provided on the inner wall of the negative pressure chamber 15.

[0048] Furthermore, the arc-shaped slide groove 30 is arranged in a wave shape, and the end of the scraper 32 is slidably connected to the closed rotary vane 19 , and the scraper 32 and the filter plate 13 rotate synchronously.

[0049] During use, in order to prevent pollutants from accumulating on the surface of the filter plate 13 for a long time and thus affecting the negative pressure drainage effect, a scraper 32 is provided. The scraper 32 rotates with the filter plate 13 and reciprocates up and down relative to the surface of the filter plate 13 under the action of the slider 31 and the arc-shaped slide groove 30, so that the pollutants on the surface of the filter plate 13 are scraped off, thereby improving the negative pressure drainage effect of the negative pressure mechanism 7, and also increasing the service life of the filter plate 13 and reducing the maintenance frequency.

[0050] like Figure 1 - Figure 6 and Figure 8-Figure 11 As shown, the collecting top plate 5 is provided with a storage bin 36 , and the storage bin 36 is connected with a connecting cavity 35 , and the connecting cavity 35 is located above the cleaning gap 18 .

[0051] During use, as the scraper 32 moves back and forth, the pollutants in the cleaning gap 18 will be continuously compressed into the connecting cavity 35, and enter the storage bin 36 through the connecting cavity 35 for collection, so that the pollutants can be centrally processed through the storage bin 36 to prevent the pollutants from entering the drainage pipe 2, and the movement cycle of the scraper 32 can be controlled by the arc-shaped slide groove 30 to improve its cleaning effect.

[0052] like Figure 1-7As shown, the adaptive sleeve 16 includes a driving sleeve 21 and an elastic limiting rod 23. The driving sleeve 21 is fixedly connected to the inside of the negative pressure chamber 15. The elastic limiting rod 23 is elastically arranged inside the driving sleeve 21. An active chamber 29 is opened inside the driving sleeve 21. The driving shaft 11 is rotatably arranged at the bottom of the active chamber 29. The elastic limiting rod 23 is elastically arranged at the top of the active chamber 29. A card and rod 26 are provided at the bottom of the elastic limiting rod 23. An arc-shaped protrusion 27 is provided on the side of the card and rod 26 away from the elastic limiting rod 23. A limiting groove matched with the arc-shaped protrusion 27 is provided at the end of the driving shaft 11, and the card and rod 26 elastically abuts against the end of the driving shaft 11.

[0053] like Figure 1-Figure 11 As shown, a push plate 34 is embedded in the inner wall of the connecting cavity 35, and the end of the push plate 34 facing away from the connecting cavity 35 is connected to the driving connecting rod 33. The top of the elastic limiting rod 23 is provided with a push plate 34 extending into the interior of the collecting top plate 5, and the end of the driving connecting rod 33 facing away from the push plate 34 is in contact with the inclined surface of the inclined protrusion 24.

[0054] Furthermore, a partition plate 28 is provided in the middle of the movable cavity 29, and an elastic member is provided between the partition plate 28 and the elastic limiting rod 23 so that the card and rod 26 elastically fit against the driving shaft 11, a pin key 25 is provided on the top of the side end surface of the elastic limiting rod 23, and the driving sleeve 21 is provided with a card groove adapted to the pin key 25.

[0055] When in use, the drive shaft 11 is engaged with the elastic limiting rod 23 through the arc-shaped protrusion 27 and the limiting groove. When the drive shaft 11 rotates, the elastic limiting rod 23 is driven to rotate through the card and rod 26, and the elastic limiting rod 23 is coaxially connected with the driving sleeve 21 through the pin key 25. However, when there is a lot of pollutants accumulated in the connecting cavity 35, the movement resistance of the scraper 32 increases, and the rotation resistance of the driving sleeve 21 increases. When the resistance of the driving sleeve 21 is too large, the arc-shaped protrusion 27 of the card and rod 26 slips, so that the elastic limiting rod 23 moves upward relative to the driving shaft 11. At the same time as the elastic limiting rod 23 moves upward, the driving connecting rod 33 is synchronously driven under the action of the inclined protrusion 24 to drive the push plate 34 to move horizontally, so that the pollutants accumulated in the connecting cavity 35 are pushed into the storage bin 36 through the push plate 34 and the pollutants in the storage bin 36 are compacted, thereby further improving the use effect of the device. When the pollutants in the connecting cavity 35 are reduced, the storage bin 36 resumes the card and engagement with the drive shaft 11, so that the driving sleeve 21 resumes rotation.

[0056] Working principle: place the flushing tube 1 and the drainage tube 2 on the same side of the affected part, flush the affected part by injecting liquid flow into the flushing tube 1, and while the liquid flow is injected into the flushing tube 1, the liquid flow will drive the negative pressure mechanism 7 through the driving mechanism 6 to form a micro-negative pressure, and the drainage tube 2 is connected to the negative pressure mechanism 7, the drainage tube 2 can perform negative pressure drainage on the affected part, thereby improving the flushing and drainage effects of the device, without the need for an additional negative pressure source, the structure is streamlined, and a filtering structure is provided inside the negative pressure mechanism 7 to filter the negative pressure drainage liquid, the flushing liquid is injected into the flushing tube 1, and while the flushing liquid is injected, the liquid impacts the rotating impeller 9, thereby driving the rotating impeller 9 to drive the driving shaft 11 to rotate, thereby driving the negative pressure mechanism 7 through the driving shaft 11, and the driving shaft 11 drives the negative pressure mechanism 7, and the driving shaft 11 drives the driving shaft 11. The adaptive sleeve 16 is driven to rotate by the rotating impeller 9, and the adaptive sleeve 16 drives the variable vane 14 to rotate in the negative pressure chamber 15 as it rotates. Since the adaptive sleeve 16 is eccentrically arranged inside the negative pressure chamber 15, and the variable vane 14 divides the negative pressure chamber 15, as the variable vane 14 rotates, the liquid at one end of the negative pressure chamber 15 can be actively transported to the other end, thereby realizing negative pressure drainage of the drainage tube 2. The driving shaft 11 can drive the drainage tube 2 to perform negative pressure drainage synchronously while the device is flushing, thereby simplifying the device structure and improving the cleaning and drainage effect. By providing a first vane seat 17, a sealed vane 19 and a second vane seat 20, the variable vane 14 divides the adaptive sleeve 16 into The two cavities change in volume as the adaptive sleeve 16 rotates, thereby realizing negative pressure drainage of the drainage tube 2, and the variable rotary vane 14 will also drive the filter plate 13 to rotate in the internal ring line of the negative pressure chamber 15 while rotating, so that the drainage liquid in the drainage tube 2 can be filtered through the rotating setting of the filter plate 13. At the same time, the rotating setting of the filter plate 13 can effectively avoid the situation where the drainage tube 2 is blocked and affects the drainage effect. In order to avoid the long-term accumulation of pollutants on the surface of the filter plate 13 and thus affect the negative pressure drainage effect, a scraper 32 is provided. The scraper 32 rotates with the filter plate 13, and reciprocates up and down relative to the surface of the filter plate 13 under the action of the slider 31 and the arc-shaped slide groove 30, so that the pollutants on the surface of the filter plate 13 are scraped off, thereby increasing the negative pressure of the negative pressure mechanism 7. The drainage effect also increases the service life of the filter plate 13 and reduces the maintenance frequency. As the scraper 32 reciprocates, the pollutants in the cleaning gap 18 will be continuously compressed into the connecting chamber 35 and enter the storage bin 36 through the connecting chamber 35 for collection, so that the pollutants can be centrally processed through the storage bin 36 to prevent the pollutants from entering the interior of the drainage pipe 2, and the movement cycle of the scraper 32 is controlled by the arc-shaped slide groove 30 to improve its cleaning effect. The drive shaft 11 is engaged with the limit groove and the elastic limit rod 23 through the arc-shaped protrusion 27. When the drive shaft 11 rotates, the elastic limit rod 23 is driven to rotate through the card and rod 26, and the elastic limit rod 23 is coaxially connected to the drive sleeve 21 through the pin key 25. However, when there is a lot of pollutants accumulated in the connecting chamber 35,The resistance of the scraper 32 to movement increases, and the resistance of the drive sleeve 21 to rotation increases. When the resistance of the drive sleeve 21 is too large, the arc-shaped protrusion 27 of the card and rod 26 slips, so that the elastic limit rod 23 moves up relative to the drive shaft 11. When the elastic limit rod 23 moves up, the driving connecting rod 33 is synchronously driven to drive the push plate 34 to move horizontally under the action of the inclined protrusion 24, so that the accumulated pollutants in the connecting cavity 35 are pushed into the storage bin 36 through the push plate 34 and the pollutants in the storage bin 36 are compacted, further improving the use effect of the device. The pollutants in the connecting cavity 35 are reduced, and the storage bin 36 resumes the card and the drive shaft 11, so that the drive sleeve 21 resumes rotation.
