Description

Technical Field

[0001] This invention relates to the field of medical technology, and more particularly to a fluid drainage device for tumor care. Background Technology

[0002] In clinical oncology, cases of tumor-induced fluid accumulation are common. Tumors can cause ascites, and when the amount of fluid in the abdominal cavity exceeds 200ml under pathological conditions, it is called ascites. When a large amount of ascites affects the patient's breathing or the patient's abdominal distension is severe and unbearable, paracentesis can be performed to relieve symptoms. The traditional method uses a rubber tubing connected to a standard puncture needle, through which the ascites fluid is slowly aspirated using a syringe. After aspiration, the doctor needs to remove the syringe and connect a plastic indwelling catheter and a sterile drainage bag to an intravenous line for gravity drainage. However, removing the syringe and connecting the intravenous line is inconvenient for the doctor and can easily lead to infection.

[0003] Therefore, how to design a fluid drainage device for tumor care that does not require removal of the syringe and is easy to use is the technical problem that this invention needs to solve. Summary of the Invention

[0004] To overcome the inconvenience and risk of infection caused by the need to remove the syringe to drain the fluid after the syringe tube is full and then reinstall it for a cycle, the present invention addresses the problem of providing a fluid drainage device for tumor care that does not require removal of the syringe and is easy to use.

[0005] The technical implementation of the present invention is as follows: a drainage device for tumor care includes a sleeve rod, a bracket fixedly connected to the bottom of the sleeve rod, a lifting rod slidably connected inside the sleeve rod, a first fixing clamp fixedly connected to the side of the lifting rod away from the bracket, a first rotating clamp rotatably connected to the first fixing clamp, a first torsion spring symmetrically fixed between the first rotating clamp and the first fixing clamp, a syringe tube placed between the first rotating clamp and the first fixing clamp, a piston rod slidably connected inside the syringe tube, a first inlet opening of the syringe tube, a drainage tube sleeved on the first inlet opening, a puncture needle connected to the side of the drainage tube away from the syringe tube, a retainer symmetrically fixedly connected to the sleeve rod, a collection bottle retaining the retainer, a second inlet opening at the top of the collection bottle, an outlet opening at the bottom of the syringe tube near the first inlet opening, a conduit sleeved between the second inlet opening and the outlet opening, a first valve installed on the conduit, an adjusting component for adjusting the height of the syringe tube provided on the side of the lifting rod near the bracket, and a squeezing component for closing the drainage tube provided on the side of the lifting rod near the first fixing clamp.

[0006] Optionally, the adjustment component includes a buckle that is slidably connected to the lifting rod. A telescopic spring is installed between the buckle and the lifting rod. The sleeve rod has equally spaced locking holes, and the buckle engages with the locking holes.

[0007] Optionally, the extrusion assembly includes a support rod, which is fixed to the side of the lifting rod near the bracket. A first connecting rod is fixed to the support rod, and a placement frame is fixed to the side of the first connecting rod away from the support rod. A sliding rod is fixed to the top of the placement frame, and a pressure plate is slidably connected to the sliding rod. An extrusion protrusion is fixed to the bottom of the pressure plate, and the extrusion protrusion engages with the drainage tube in an extrusion fit.

[0008] Optionally, the fluid drainage device for tumor care further includes an anti-detachment component, which is disposed on the first fixing clamp. The anti-detachment component is used to prevent the syringe tube from detaching from the drainage tube. The anti-detachment component includes a mounting frame, which is fixedly connected to the first fixing clamp. A rack is slidably connected inside the mounting frame. An L-shaped rod is fixedly connected to the side of the rack near the drainage tube. A rotating rod is rotatably connected to the side of the mounting frame near the piston rod. A gear is fixedly connected to the side of the rotating rod near the piston rod. The gear is located inside the mounting frame and meshes with the rack. A handle is fixedly connected to the rotating rod. A support rod is provided with a support and fixing component for supporting and fixing the drainage tube.

[0009] Optionally, a U-shaped lever is fixed to the side of the rack away from the L-shaped rod, and the U-shaped lever engages with the left side of the piston rod.

[0010] Optionally, the support and fixing assembly includes a second fixing clip, which is fixed to the support rod. The second fixing clip is rotatably connected to a second rotating clip. A second torsion spring is symmetrically fixed between the second rotating clip and the second fixing clip. The first rotating clip and the first fixing clip cooperate to clamp the drainage tube.

[0011] Optionally, the fluid drainage device for tumor care also includes a lifting assembly, which is disposed between the pressure plate and the L-shaped rod. The lifting assembly is used to drive the squeezing protrusion to automatically press the drainage tube. The lifting assembly includes a push rod, which is fixed to the pressure plate. A push plate is fixed to the top of the L-shaped rod. The push plate and the push rod are in a squeezing fit. A pressure spring is installed between the slide rod and the top of the pressure plate.

[0012] Optionally, the push plate is tilted near the sides of the mounting frame.

[0013] Optionally, the fluid drainage device for tumor care also includes a stabilizing component, which is mounted on a support rod and used to fix the connection between the drainage tube and the first inlet. The stabilizing component includes a second connecting rod, which is fixed to the support rod. A third fixing clamp is fixed to the side of the second connecting rod near the syringe tube. A third rotating clamp is rotatably connected to the third fixing clamp. A third torsion spring is symmetrically fixed between the third rotating clamp and the third fixing clamp. The third rotating clamp and the third fixing clamp cooperate to clamp the connection between the drainage tube and the first inlet.

[0014] Optionally, the fluid drainage device for tumor care also includes a sampling component, which is mounted on the collection bottle and facilitates sampling by the physician. The sampling component includes a fixing tube connected to the collection bottle, a second valve installed on the fixing tube, a connecting tube connected to the side of the fixing tube away from the collection bottle, a cover connected to the side of the connecting tube away from the fixing tube, and a placement seat for placing a sampling container fixed to the side of the sleeve near the collection bottle.

[0015] This invention has the following advantages: Pulling the piston rod draws the patient's bodily fluids into the syringe tube, which then flows into the collection bottle. The collection bottle can be replaced to continue collecting the fluid, eliminating the need to disassemble the syringe, making it convenient to use and preventing infection. By observing the leftward movement of the L-shaped rod, it's known whether the piston rod has reached its leftward limit, thus preventing the piston rod from pulling the syringe tube to the left and causing it to detach from the drainage tube, resulting in fluid leakage. Through the squeezing action of the push plate and push rod, when fluid extraction stops, the squeezing protrusion automatically presses the drainage tube shut, blocking it. The third rotating clamp, in conjunction with the third fixing clamp, secures the connection between the drainage tube and the first inlet, preventing the drainage tube from detaching from the syringe tube and causing fluid leakage. Placing the sampling container on the base, covering the container opening, and opening the second valve allow the fluid in the collection bottle to flow through the fixing tube into the connecting tube and then into the sampling container. This allows for direct sampling during the extraction process, eliminating the need for the doctor to wait for the extraction to complete. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0033] Example 1

[0034] For drainage devices used in tumor care, refer to Figures 1-7 The device includes a sleeve rod 1, a bracket 2, and a lifting rod 3. The bracket 2 is fixedly connected to the bottom of the sleeve rod 1. The lifting rod 3 is slidably connected inside the sleeve rod 1. A first fixing clamp 4 is fixedly connected to the upper end of the lifting rod 3. A first rotating clamp 5 is rotatably connected to the lower part of the first fixing clamp 4. Two first torsion springs 6 are fixedly connected between the first rotating clamp 5 and the first fixing clamp 4. A syringe tube 7 is placed between the first rotating clamp 5 and the first fixing clamp 4. A piston rod 8 is slidably connected inside the syringe tube 7. A first liquid inlet 9 is opened on the right side of the syringe tube 7. A drainage tube is fitted onto the first liquid inlet 9. 10. The right end of the drainage tube 10 is connected to a puncture needle 11. Two retainers 12 are fixed to the upper part of the sleeve rod 1. A collection bottle 13 is clamped between the two retainers 12. A second inlet 14 is opened at the top of the collection bottle 13. An outlet 15 is opened on the right side of the bottom of the syringe tube 7. A conduit 16 is sleeved between the outlet 15 and the second inlet tube. A first valve 17 is installed at the lower part of the conduit 16. An adjustment component for adjusting the height of the syringe tube 7 is provided at the lower part of the lifting rod 3. A squeezing component for closing the drainage tube 10 is provided at the upper part of the lifting rod 3.

[0035] The adjustment component includes a buckle 18, which is slidably connected to the lower part of the lifting rod 3. A telescopic spring 19 is installed between the buckle 18 and the lifting rod 3. The sleeve rod 1 has equally spaced locking holes 20, and the buckle 18 is locked into the locking holes 20.

[0036] The extrusion assembly includes a support rod 21, which is fixed to the upper part of the lifting rod 3. A first connecting rod 22 is fixed to the right side of the support rod 21. A placement frame 23 is fixed to the upper end of the first connecting rod 22. Two sliding rods 24 are fixed to the top of the placement frame 23. A pressure plate 25 is slidably connected between the two sliding rods 24. An extrusion protrusion 26 is fixed to the bottom of the pressure plate 25. The extrusion protrusion 26 is extruded and engaged with the drainage tube 10.

[0037] In use, manually rotate the first rotating clamp 5 forward to open it, causing the first torsion spring 6 to deform. Place the syringe tube 7 between the first fixing clamp 4 and the first rotating clamp 5. Release the first rotating clamp 5, and under the action of the first torsion spring 6 resetting, the first rotating clamp 5 will cooperate with the first fixing clamp 4 to fix the syringe tube 7. Then, manually move the pressure plate 25 upward. The pressure plate 25 will cause the squeezing protrusion 26 to move upward, allowing the drainage tube 10 to pass through the placement frame 23. The placement frame 23 will support the drainage tube 10, and the drainage tube 10 will be fitted onto the first inlet 9 of the syringe tube 7. The conduit 16 will be fitted onto the outlet 15 of the syringe tube 7. Press the buckle 18, and the telescopic spring 19 will be compressed, allowing the lifting rod 3 to be adjusted in height. Adjust the syringe tube 7 to a suitable height. After adjusting the height, release the buckle 18, and under the action of the telescopic spring 19 resetting, the buckle 18 will reset and lock into the locking hole 20 to adjust the lifting rod. 3. Limit the position, then manually press down the pressure plate 25. The pressure plate 25 moves the squeezing protrusion 26 downward to cooperate with the placement frame 23 to clamp the drainage tube 10. Then, insert the puncture needle 11 into the patient's body. Manually move the pressure plate 25 upward. The pressure plate 25 moves the squeezing protrusion 26 upward to release the drainage tube 10. At the same time, open the first valve 17. Then manually pull the piston rod 8 to put the inside of the syringe tube 7 into a negative pressure state, thereby drawing the patient's body fluid into the syringe tube 7 and then into the collection bottle 13. When the liquid in the collection bottle 13 is full, close the first valve 17 and replace the collection bottle 13 with a new one. After replacing it with a new collection bottle 13, open the first valve 17 again to collect the liquid through the collection bottle 13 again. This solves the problem that doctors need to remove the syringe and then connect the plastic indwelling catheter and sterile drainage bag with an intravenous tube, which is inconvenient and prone to infection.

[0038] Example 2

[0039] Based on Example 1, referring to Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The fluid drainage device for tumor care also includes an anti-detachment component, which is located at the lower part of the first fixing clamp 4. The anti-detachment component is used to prevent the syringe tube 7 from detaching from the drainage tube 10. The anti-detachment component includes a mounting frame 27, which is fixed to the lower part of the first fixing clamp 4. A rack 28 is slidably connected inside the mounting frame 27. An L-shaped rod 29 is fixed to the right end of the rack 28. A rotating rod 30 is rotatably connected to the front left side of the mounting frame 27. A gear 31 is fixed to the rear of the rotating rod 30. The gear 31 is located inside the mounting frame 27 and meshes with the rack 28. A handle 32 is fixed to the front end of the rotating rod 30. A U-shaped lever 33 is fixed to the rear left side of the rack 28. The U-shaped lever 33 pushes and engages with the left side of the piston rod 8. A support and fixing component for supporting and fixing the drainage tube 10 is provided on the upper part of the support rod 21.

[0040] The support and fixing assembly includes a second fixing clip 34, which is fixed to the right end of the support rod 21. A second rotating clip 35 is rotatably connected to the lower part of the second fixing clip 34. Two second torsion springs 36 are fixed between the second rotating clip 35 and the second fixing clip 34. The first rotating clip 5 and the first fixing clip 4 cooperate to clamp the drainage tube 10.

[0041] During the installation of the drainage tube 10, manually open the second rotating clamp 35. The second torsion spring 36 deforms, and the drainage tube 10 is placed between the second fixed clamp 34 and the second rotating clamp 35. Release the second rotating clamp 35, and then, under the action of the second torsion spring 36 resetting, drive the second rotating clamp 35 to cooperate with the second fixed clamp 34 to fix the drainage tube 10. When aspirating the accumulated fluid, manually turn the handle 32. The handle 32 drives the rotating rod 30 to rotate, the rotating rod 30 drives the gear 31 to rotate, the gear 31 drives the rack 28 to move to the left, the rack 28 drives the U-shaped lever 33 and the L-shaped rod 29 to move to the left, and the U-shaped lever 33 pushes... The piston rod 8 creates a negative pressure inside the syringe tube 7, thereby drawing the patient's body fluid into the syringe tube 7. When the L-shaped rod 29 contacts the right side of the syringe tube 7, it indicates that the piston rod 8 has moved to its limit to the left, prompting the doctor to stop turning the handle 32. After the piston rod 8 has moved to its limit to the left, to prevent the piston rod 8 from continuing to pull the syringe tube 7 to the left and disengaging it from the drainage tube 10, causing fluid leakage, the handle 32 is manually reversed. The handle 32 drives the rotating rod 30 to reverse, and the rotating rod 30 drives the U-shaped lever 33 and the L-shaped rod 29 to move to the right and reset through the gear 31 and rack 28.

[0042] Reference Figure 1 , Figure 2 and Figure 12 The fluid drainage device for tumor care also includes a lifting assembly, which is located between the pressure plate 25 and the L-shaped rod 29. The lifting assembly is used to drive the squeezing protrusion 26 to automatically press the drainage tube 10. The lifting assembly includes a push rod 37, which is fixed to the front side of the pressure plate 25. A push plate 38 is fixed to the top of the L-shaped rod 29. The push plate 38 is inclined on the left and right sides. The push plate 38 and the push rod 37 are squeezed together. Pressure springs 39 are installed between the upper part of the two slide rods 24 and the top of the pressure plate 25.

[0043] After the drainage tube 10 passes through the placement frame 23, the squeezing protrusion 26 presses the drainage tube 10 shut under the elastic force of the pressure spring 39, thus blocking the drainage tube 10. When the fluid is first aspirated, the L-shaped rod 29 moves to the left, causing the push plate 38 to move to the left. Since the left and right sides of the push plate 38 are inclined, the left side of the push plate 38 pushes the push rod 37 upward. The push rod 37 drives the pressure plate 25 and the squeezing protrusion 26 upward, compressing the pressure spring 39. The squeezing protrusion 26 releases the drainage tube 10, allowing the patient's body fluid to be drawn into the syringe tube 7 through the drainage tube 10. When the right side of the push plate 38 contacts the push rod 37... Then, under the action of the pressure spring 39 resetting, the pressure plate 25 and the squeezing protrusion 26 move downward to reset. When the L-shaped rod 29 moves to the right to reset, it then moves the push plate 38 to the right to reset. The right side of the push plate 38 pushes the push rod 37 upward. The push rod 37 drives the pressure plate 25 and the squeezing protrusion 26 to move upward. The pressure spring 39 is compressed. When the left side of the push plate 38 contacts the push rod 37, the pressure plate 25 and the squeezing protrusion 26 move downward to reset under the action of the pressure spring 39. In this way, when the drainage of accumulated fluid stops, the squeezing protrusion 26 can automatically press the drainage tube 10 to block the drainage tube 10.

[0044] Reference Figure 1 , Figure 2 , Figure 13 and Figure 14 The fluid drainage device for tumor care also includes a stabilizing component, which is mounted on the support rod 21. The stabilizing component is used to fix the connection between the drainage tube 10 and the first inlet 9. The stabilizing component includes a second connecting rod 40, which is fixed to the middle of the support rod 21. A third fixing clamp 41 is fixed to the upper end of the second connecting rod 40. A third rotating clamp 42 is rotatably connected to the lower part of the third fixing clamp 41. Two third torsion springs 43 are fixed between the third rotating clamp 42 and the third fixing clamp 41. The third rotating clamp 42 and the third fixing clamp 41 cooperate to clamp the connection between the drainage tube 10 and the first inlet 9.

[0045] During the installation of the drainage tube 10, the third rotating clamp 42 is manually rotated backward, causing the third torsion spring 43 to deform. After the drainage tube 10 is fitted onto the connection of the syringe tube 7, the drainage tube 10 is located between the third fixing clamp 41 and the third rotating clamp 42. The third rotating clamp 42 is then released, and under the action of the third torsion spring 43 resetting, the third rotating clamp 42 is driven to cooperate with the third fixing clamp 41 to fix the connection between the drainage tube 10 and the first liquid inlet 9, preventing the drainage tube 10 from detaching from the syringe tube 7 and causing liquid leakage.

[0046] Reference Figure 1 , Figure 2 and Figure 15The fluid drainage device for tumor care also includes a sampling component, which is set on the collection bottle 13. The sampling component facilitates sampling by doctors. The sampling component includes a fixing tube 44, which is connected to the lower part of the collection bottle 13. A second valve 45 is installed on the fixing tube 44. A connecting tube 46 is connected to the rear end of the fixing tube 44. A cover 47 is connected to the lower end of the connecting tube 46. A placement seat 48 for placing a sampling container is fixedly connected to the middle of the sleeve rod 1.

[0047] When sampling is required, place the sampling container on the placement seat 48, cover the opening of the sampling container with the cover 47, open the second valve 45, so that the liquid in the collection bottle 13 enters the connecting tube 46 through the fixed tube 44, and then flows into the sampling container. When the liquid in the sampling container reaches an appropriate amount, close the second valve 45. In this way, sampling can be carried out directly during the liquid aspiration process, so that the doctor does not need to wait for the liquid aspiration to be completed before taking the sample.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
