Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for preventing and draining fluid accumulation in internal medicine. Background Technology

[0002] The pleural cavity is a space between the visceral and parietal layers of the pleura. Under normal circumstances, it secretes some fluid to lubricate the pleural cavity. However, if too much fluid is secreted, it will lead to pleural effusion. When a patient has pleural effusion, the first symptoms will be cough and chest pain, often manifested as a dry cough accompanied by stabbing chest pain. The chest pain will worsen when coughing or taking a deep breath. Secondly, the patient will also experience difficulty breathing. When there is a small amount of effusion, the symptoms are not obvious or there may only be a slight feeling of chest tightness. However, if there is a large amount of effusion, there will be obvious difficulty breathing. Therefore, drainage equipment is an essential treatment device, which plays an important role in draining the fluid accumulated under the skin or in the cavity from the body.

[0003] In clinical practice, when performing pleural drainage to remove pleural effusion in internal medicine patients, after each syringe is filled, the latex tubing must be clamped with hemostats, the syringe emptied, and then the latex tubing reconnected. The hemostats are then released and aspiration continues. This not only makes it inconvenient for medical staff to perform the work of draining effusion, but also causes some discomfort to the patient due to the inconsistent aspiration speed when medical staff change the aspiration site. Furthermore, pleural effusion contains relatively viscous fluid, which can cause blockage of the drainage tube during the drainage process. When the drainage tube is blocked, it needs to be replaced multiple times, which can cause more pain for the patient. Traditional drainage needles are difficult to position after being inserted into the affected area, which can easily cause secondary damage and discomfort to the patient, and therefore need to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a drainage device for preventing blockage of pleural effusion, in order to solve the problems mentioned in the prior art, such as low drainage efficiency, the presence of viscous fluid in pleural effusion causing blockage of the drainage tube during drainage, the need for multiple replacements of the drainage tube when it is blocked, which causes more pain to the patient, and the difficulty in positioning the traditional drainage needle after it is inserted into the affected area, which can easily cause secondary damage to the patient.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an internal medicine fluid accumulation anti-blockage drainage device, comprising a drainage tube, a push plate, a drainage needle, and a drain port. The drainage needle is installed at one end of the drainage tube. A piston plate is slidably installed inside the drainage tube. A push rod is fixedly installed on one side of the piston plate. One end of the push rod is fixedly connected to the push plate. A dilution component for agitating the accumulated fluid is provided inside the drainage tube. A fixing ring seat is fixedly installed at one end of the drainage tube. A guide rod is slidably installed on the fixing ring seat. A positioning plate is fixedly connected to one end of the guide rod. A positioning ring sleeve is rotatably installed on the fixing ring seat. The dilution component includes a first hollow rotating shaft and a second hollow rotating shaft rotatably installed inside the drainage tube. Agitating rods are axially arranged on the side walls of the first hollow rotating shaft and the second hollow rotating shaft.

[0006] As a further preferred embodiment of this technical solution: a gear is fixedly sleeved on the portion of the first hollow rotating shaft near the top, a rack is meshed with one side of the gear, and one end of the rack is fixedly connected to one side surface of the piston plate.

[0007] As a further preferred embodiment of this technical solution: a traction rope is wound around the portion of the second hollow shaft near the top, one end of the traction rope is connected to the first hollow shaft, and a torsion spring is installed on the portion of the second hollow shaft near the bottom, one end of the torsion spring is fixedly connected to the second hollow shaft, and the other end of the torsion spring is fixedly connected to the inner wall of the drainage tube.

[0008] As a further preferred embodiment of this technical solution: a first piston cylinder is fixedly installed on both sides of the drainage tube, one end of the piston rod of each of the two first piston cylinders is fixedly connected to the push plate, the input end of each of the two first piston cylinders is connected to disinfectant through a conduit, and the output end of each of the two first piston cylinders is connected to the inside of the first hollow shaft and the second hollow shaft through a pipe respectively.

[0009] As a further preferred embodiment of this technical solution: the first hollow shaft and the second hollow shaft are provided with drainage holes axially on their sidewalls, and the drainage holes are in communication with the interior of the first hollow shaft and the second hollow shaft.

[0010] As a further preferred embodiment of this technical solution: a positioning suction cup is installed on one side surface of the positioning disk, the guide rod passes through the fixing ring seat, and an arc-shaped limiting groove is longitudinally arranged on the side wall of the guide rod.

[0011] As a further preferred embodiment of this technical solution: an arc-shaped through groove is provided on the side wall of the fixed ring seat, the arc-shaped limiting groove is located inside the arc-shaped through groove, and an arc-shaped retaining strip protrudes from the inner ring wall of the positioning ring sleeve, the arc-shaped retaining strip is located inside the arc-shaped through groove and engages with the arc-shaped limiting groove.

[0012] As a further preferred embodiment of this technical solution: the width of the arc-shaped limiting groove is smaller than the width of the arc-shaped through groove, the thickness of the arc-shaped locking strip matches the arc-shaped limiting groove, and both the upper and lower surfaces of the arc-shaped locking strip are provided with a rubber anti-slip layer.

[0013] As a further preferred embodiment of this technical solution: a hollow ring seat is provided in the middle of the positioning disk, the hollow ring seat is fixedly connected to the positioning disk by a fixing rod, the drainage needle passes through the hollow ring seat, a second piston cylinder is installed on the positioning disk, the second piston cylinder stores anesthetic, and the piston rod of the second piston cylinder is connected to the fixing ring seat.

[0014] As a further preferred embodiment of this technical solution: the output end of the second piston cylinder is connected to the interior of the hollow ring seat through a pipe, and an atomizing nozzle is axially arranged on the lower surface of the hollow ring seat, and the atomizing nozzle is connected to the interior of the hollow ring seat.

[0015] The beneficial effects of this invention are: This invention, by setting up a dilution component, allows the piston plate to move and drive the rack to move when the drainage tube is used to extract the accumulated liquid. As the rack moves, it can mesh with the gear, thereby causing the first hollow shaft to rotate. Simultaneously, the rotation of the first hollow shaft can wind up one end of the traction rope, which in turn pulls the second hollow shaft to rotate, causing the torsion spring to gradually tighten. The rotation of the first and second hollow shafts agitates and disperses the thick accumulated liquid entering the drainage tube, preventing blockage when the liquid is discharged from the drainage tube.

[0016] 2. This invention features two first pistons. When the piston plate is squeezed by the push plate and the push rod, the accumulated liquid in the drainage tube can be squeezed out. At the same time, as the push plate moves, the disinfectant in the first piston is squeezed out and sent into the first hollow rotating shaft and the second hollow rotating shaft respectively, and discharged through multiple drainage holes. While being discharged, the first hollow rotating shaft and the second hollow rotating shaft rotate synchronously, thereby stirring and mixing the disinfectant with the accumulated liquid. This effectively mixes the thick accumulated liquid, thereby effectively avoiding blockage during the discharge of the accumulated liquid and ensuring good drainage effect.

[0017] 3. By setting a positioning plate, the present invention can first fix the positioning plate to the patient's skin by suction cup when aspirating fluid. Then, the drainage tube is pushed to move so that the drainage needle is inserted into the affected area. At this time, the guide rod slides on the fixed ring seat. When the drainage needle enters a certain depth, the positioning ring can be rotated to limit the guide rod, thereby limiting the drainage needle and avoiding the discomfort caused by the drainage needle continuing to penetrate during the process of aspirating fluid.

[0018] 4. By setting a hollow ring seat, after the positioning plate is attached and fixed to the patient's skin, the drainage tube can be moved. At the same time, the piston rod in the second piston cylinder is pushed, squeezing the anesthetic in the second piston cylinder into the hollow ring seat. The anesthetic is then sprayed onto the patient's affected area through multiple atomizing nozzles, reducing the pain caused by the drainage needle piercing the affected area and relieving the pain generated during drainage.

[0021] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0022] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, an internal medicine fluid accumulation prevention and drainage device includes a drainage tube 1, a push plate 2, a drainage needle 3, and a drain port 5. The drainage needle 3 is installed at one end of the drainage tube 1. A piston plate 13 is slidably installed inside the drainage tube 1. A push rod 12 is fixedly installed on one side of the piston plate 13. One end of the push rod 12 is fixedly connected to the push plate 2. A dilution component for agitating the accumulated fluid is provided inside the drainage tube 1. A fixing ring seat 7 is fixedly installed at one end of the drainage tube 1. A guide rod 10 is slidably installed on the fixing ring seat 7. A positioning plate 6 is fixedly connected to one end of the guide rod 10. A positioning ring sleeve 8 is rotatably installed on the fixing ring seat 7. The drainage needle 3 is detachably connected to the drainage tube 1, and a one-way valve is provided at the connection between the drainage tube 1 and the drainage needle 3. A one-way valve is also provided at the drain port 5, and the flow directions of the two one-way valves are arranged in opposite directions. The dilution assembly includes a first hollow shaft 14 and a second hollow shaft 15 rotatably installed inside the drainage tube 1, and stirring rods 18 are axially arranged on the side walls of the first hollow shaft 14 and the second hollow shaft 15. A gear 22 is fixedly sleeved on the part of the first hollow rotating shaft 14 near the top. A rack 21 is meshed with one side of the gear 22. One end of the rack 21 is fixedly connected to one side surface of the piston plate 13. A traction rope 17 is wound on the part of the second hollow rotating shaft 15 near the top. One end of the traction rope 17 is connected to the first hollow rotating shaft 14. A torsion spring 16 is installed on the part of the second hollow rotating shaft 15 near the bottom. One end of the torsion spring 16 is fixedly connected to the second hollow rotating shaft 15. The other end of the torsion spring 16 is fixedly connected to the inner wall of the drainage tube 1. During operation, when draining, the push plate 2 can be pulled, causing the push rod 12 to move, which in turn moves the piston plate 13, creating negative pressure inside the drainage tube 1. This pressure then guides the accumulated fluid into the drainage tube 1 through the drainage needle 3. When the piston plate 13 moves, it moves the rack 21, which in turn engages the gear 22. The rotation of the gear 22 simultaneously drives the first hollow shaft 14 to rotate. The rotation of the first hollow shaft 14 simultaneously winds up one end of the traction rope 17, thereby pulling the first... The rotation of the second hollow shaft 15, while the second hollow shaft 15 rotates, causes the torsion spring 16 to be in a taut state. The rotation of the first hollow shaft 14 and the second hollow shaft 15 can be synchronized, thereby using the stirring rod 18 to agitate and disperse the accumulated liquid inside the drainage tube 1. This can prevent the thick accumulated liquid from clogging the drainage tube 1 when it is discharged, effectively avoiding the need to replace the drainage tube 1 due to blockage caused by thick accumulated liquid. This allows for stable liquid extraction and is easy to use.

[0024] Example 2: Figure 1 , Figure 2 , Figure 4 and Figure 9 As shown, first piston cylinders 4 are fixedly installed on both sides of the drainage tube 1. One end of the piston rod of each of the two first piston cylinders 4 is fixedly connected to the push plate 2. The input ends of the two first piston cylinders 4 are connected to disinfectant through conduits. The output ends of the two first piston cylinders 4 are connected to the inside of the first hollow rotating shaft 14 and the second hollow rotating shaft 15 through pipes respectively. Drainage holes 20 are axially opened on the side walls of the first hollow rotating shaft 14 and the second hollow rotating shaft 15. The drainage holes 20 are connected to the inside of the first hollow rotating shaft 14 and the second hollow rotating shaft 15. One-way valves are installed at both the input and output ends of the first piston cylinders 4, and the flow directions of the two one-way valves are reversed. During operation, when the push plate 2 is moved to extract the accumulated liquid, the piston rod inside the first piston cylinder 4 can be moved simultaneously by the push plate 2, thus allowing the disinfectant to be drawn into the first piston cylinder 4. When the push plate 2 is pushed to move and discharge the accumulated liquid in the drainage tube 1, the piston plate 13 moves, which drives the rack 21 to move and mesh with the gear 22 to rotate. The first hollow shaft 14 and the second hollow shaft 15 rotate synchronously, and the disinfectant inside the first piston cylinder 4 is discharged through the pipes. The liquid is discharged into the first hollow rotating shaft 14 and the second hollow rotating shaft 15, and evenly discharged into the drainage tube 1 through multiple drainage holes 20 on the first hollow rotating shaft 14 and the second hollow rotating shaft 15. At the same time, the first hollow rotating shaft 14 and the second hollow rotating shaft 15 rotate to agitate the accumulated liquid and disinfectant, effectively diluting the thick accumulated liquid. Meanwhile, the disinfectant can kill bacteria in the accumulated liquid, effectively reducing the bacteria contained in the discharged accumulated liquid and diluting the thick accumulated liquid to avoid clogging the drainage tube 1 during discharge. After the drainage fluid is removed, the discharged disinfectant can be used to disinfect the inside of the drainage tube 1, thus allowing the drainage tube 1 to be reused.

[0025] Example 3: As Figure 2 , Figure 5 , Figure 6 and Figure 10 As shown, a positioning suction cup 11 is installed on one side surface of the positioning disk 6, a guide rod 10 passes through the fixing ring seat 7, and an arc-shaped limiting groove 26 is longitudinally arranged on the side wall of the guide rod 10; an arc-shaped through groove 25 is opened on the side wall of the fixing ring seat 7, and the arc-shaped limiting groove 26 is located inside the arc-shaped through groove 25. An arc-shaped retaining strip 24 protrudes from the inner ring wall of the positioning ring sleeve 8, and the arc-shaped retaining strip 24 is located inside the arc-shaped through groove 25 and engages with the arc-shaped limiting groove 26; the width of the arc-shaped limiting groove 26 is smaller than the width of the arc-shaped through groove 25, the thickness of the arc-shaped retaining strip 24 matches the arc-shaped limiting groove 26, and both the upper and lower surfaces of the arc-shaped retaining strip 24 are provided with a rubber anti-slip layer; During the procedure, when draining the fluid, the positioning plate 6 is first fixed to the skin around the patient's affected area via the positioning suction cup 11. Then, the drainage tube 1 is moved closer to the positioning plate 6. At this time, the guide rod 10 passes through the fixing ring seat 7 and moves to one side of the fixing ring seat 7. The drainage needle 3 gradually pierces the affected area. When the drainage needle 3 has entered to a certain depth, the positioning ring sleeve 8 can be rotated, causing the arc-shaped retaining strip 24 on the positioning ring sleeve 8 to rotate at a certain angle along the arc-shaped through groove 25, thereby causing the arc-shaped retaining strip 24 to engage inside the arc-shaped limiting groove. The thickness of strip 24 is less than the width of arc-shaped through groove 25, allowing it to rotate flexibly within the arc-shaped through groove 25. Furthermore, since both the upper and lower surfaces of arc-shaped strip 24 are provided with rubber anti-slip layers, when arc-shaped strip 24 is inserted into arc-shaped limiting groove 26, the tightness of the engagement is increased, thereby effectively positioning guide rod 10. This prevents guide rod 10 from sliding on fixed ring seat 7, thus preventing the drainage needle 3 from continuing to pierce the affected area. This limits the drainage needle 3, avoiding discomfort caused by the drainage needle 3 continuing to pierce during the drainage of fluid.

[0026] Example 4: Figure 2 , Figure 3 and Figure 8 As shown, a hollow ring seat 19 is provided in the middle of the positioning disk 6. The hollow ring seat 19 is fixedly connected to the positioning disk 6 by a fixing rod. The drainage needle 3 passes through the hollow ring seat 19. A second piston cylinder 9 is installed on the positioning disk 6. The second piston cylinder 9 stores anesthetic. The piston rod of the second piston cylinder 9 is connected to the fixing ring seat 7. The output end of the second piston cylinder 9 is connected to the interior of the hollow ring seat 19 through a pipe. An atomizing nozzle 23 is axially arranged on the lower surface of the hollow ring seat 19. The atomizing nozzle 23 is connected to the interior of the hollow ring seat 19. During operation, when the positioning plate 6 is attached to the patient's skin, the drainage tube 1 is pushed to move closer to the positioning plate 6. At the same time, the piston rod inside the second piston cylinder 9 is squeezed, causing the anesthetic inside the second piston cylinder 9 to be squeezed out and sent into the hollow ring seat 19 through the pipe. Then, the anesthetic is atomized and sprayed onto the affected area through multiple atomizing nozzles 23 provided on the lower surface of the hollow ring seat 19. At the same time, when the drainage tube 1 is pushed to move, the drainage needle 3 can pass through the hollow ring seat 19 and pierce the patient's affected area, which can reduce the pain caused by the drainage needle 3 piercing the affected area and relieve the pain generated by the drainage.

[0027] Working principle: First, connect the drainage needle 3 to the drainage tube 1. Then, connect the drain port 5 to the storage bag through a conduit, and connect the input ends of the two first pistons to the disinfectant through conduits. Next, fix the positioning plate 6 to the skin around the patient's affected area through the positioning suction cup 11. Then, push the drainage tube 1 to move closer to the positioning plate 6. At this time, the guide rod 10 passes through the fixing ring seat 7 and moves to one side of the fixing ring seat 7. The drainage needle 3 gradually penetrates into the affected area. When the drainage needle 3 has entered a certain depth, the positioning ring sleeve 8 can be rotated, so that the arc-shaped retaining strip 24 on the positioning ring sleeve 8 rotates at a certain angle along the arc-shaped through groove 25, thereby... The arc-shaped retaining strip 24 is inserted into the arc-shaped limiting groove. Since the thickness of the arc-shaped retaining strip 24 is less than the width of the arc-shaped through groove 25, it can rotate flexibly within the arc-shaped through groove 25. Furthermore, since both the upper and lower surfaces of the arc-shaped retaining strip 24 are provided with rubber anti-slip layers, when the arc-shaped retaining strip 24 is inserted into the arc-shaped limiting groove 26, the tightness of the engagement can be increased, thereby effectively positioning the guide rod 10. This prevents the guide rod 10 from sliding on the fixed ring seat 7, thus preventing the drainage needle 3 from continuing to pierce the affected area. This limits the drainage needle 3 and avoids the discomfort caused by the drainage needle 3 continuing to pierce during the drainage of fluid. When the positioning plate 6 is attached to the patient's skin, the drainage tube 1 is pushed to move closer to the positioning plate 6. At the same time, the piston rod in the second piston cylinder 9 is squeezed, causing the anesthetic in the second piston cylinder 9 to be squeezed out and sent into the hollow ring seat 19 through the pipe. Then, the anesthetic is sprayed onto the affected area through multiple atomizing nozzles 23 on the lower surface of the hollow ring seat 19. At the same time, when the drainage tube 1 is pushed to move, the drainage needle 3 can pass through the hollow ring seat 19 and pierce the patient's affected area, which can reduce the pain caused by the drainage needle 3 piercing the affected area and relieve the pain generated by the affected area during drainage. During drainage, the push plate 2 can be pulled, causing the push rod 12 to move, which in turn moves the piston plate 13, creating negative pressure inside the drainage tube 1. This pressure then guides the accumulated fluid into the drainage tube 1 through the drainage needle 3. When the piston plate 13 moves, it moves the rack 21, which in turn engages the gear 22. The rotation of the gear 22 simultaneously rotates the first hollow shaft 14, which in turn winds up one end of the traction rope 17, thereby pulling the second hollow shaft 17. As the first hollow shaft 14 rotates and the second hollow shaft 15 rotates simultaneously, the torsion spring 16 is in a taut state. The first hollow shaft 14 and the second hollow shaft 15 can rotate synchronously, thereby using the stirring rod 18 to agitate and disperse the accumulated liquid inside the drainage tube 1. This can prevent the thick accumulated liquid from clogging the drainage tube 1 when it is discharged, effectively avoiding the need to replace the drainage tube 1 due to blockage caused by thick accumulated liquid. This allows for stable liquid extraction and is easy to use. When the push plate 2 is pulled to extract the accumulated liquid, the piston rod inside the first piston cylinder 4 can be pulled to move at the same time by the push plate 2, so that the disinfectant can be sucked into the first piston cylinder 4. When the push plate 2 is moved, the accumulated liquid in the drainage tube 1 can be discharged through the drain port 5. At this time, the piston plate 13 moves, which can drive the rack 21 to move and mesh with the gear 22 to rotate. The first hollow shaft 14 rotates to unwind the traction rope 17. At the same time, the torque of the torsion spring 16 drives the second hollow shaft 15 to rotate synchronously. Meanwhile, the disinfectant inside the first piston cylinder 4 is discharged through the pipe into the first hollow shaft 14 and the second hollow shaft 15 respectively, and is evenly discharged into the drainage tube 1 through multiple drain holes 20 on the first hollow shaft 14 and the second hollow shaft 15. At the same time, the rotation of the first hollow shaft 14 and the second hollow shaft 15 agitates the accumulated liquid and disinfectant, effectively diluting the thick accumulated liquid. At the same time, the disinfectant can kill the bacteria in the accumulated liquid, which can effectively reduce the bacteria contained in the discharged accumulated liquid and dilute the thick accumulated liquid to avoid clogging the drainage tube 1 when discharged. After the drainage fluid is drained, the drainage needle 3 can be disassembled, and then the push plate 2 and piston plate 13 can be pushed and pulled. The discharged disinfectant can be used to clean and disinfect the inside of the drainage tube 1, so that the drainage tube 1 can be reused.
