Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to a gastroenterology ascites drainage device. Background Technology

[0002] Ascites is a common condition in gastroenterology, often caused by liver disease, gastrointestinal inflammation, tumors, and other digestive system-related diseases. When the amount of fluid in the abdominal cavity exceeds 200 ml, it can lead to serious problems such as abdominal distension, difficulty breathing, and even kidney failure. Ascites drainage is a common treatment in gastroenterology, primarily aimed at relieving symptoms such as abdominal distension and difficulty breathing caused by ascites accumulation.

[0003] The procedure for ascites drainage typically involves inserting a needle or catheter into the abdominal cavity to drain excess fluid. Strict aseptic techniques must be followed throughout the procedure to prevent infection, and close monitoring of the drainage and patient response is essential to ensure unobstructed drainage and prevent complications. However, current techniques make it difficult to maintain patient positioning and fix the needle during ascites drainage, leading to needle displacement and poor sealing of the puncture site. Furthermore, adjusting the drainage rate promptly as the amount of ascites decreases can cause patient discomfort and, in severe cases, complications. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a gastroenterology ascites drainage device that facilitates stable patient positioning and needle placement. Utilizing electromagnetic principles combined with a modular structure, the device features a magnetic adjustment mechanism that dynamically adjusts the drainage speed based on the amount of ascites in the patient's abdominal cavity without altering the catheter's shape. When the amount of ascites decreases, the drainage speed is promptly reduced, and drainage is stopped when the drainage bag reaches a fixed volume, thus avoiding patient discomfort.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention provides a gastroenterology ascites drainage device, including a support mechanism, two support mechanisms are symmetrically arranged, a pull-out bearing mechanism is provided on the upper part of the support mechanism, a positioning mechanism is movably provided on the pull-out bearing mechanism, a transition mechanism is provided on the positioning mechanism, and a puncture needle is connected to the transition mechanism; Furthermore, the pull-out bearing mechanism includes a bearing plate, a tension plate, and a vertical plate. The bearing plate and the tension plate are respectively mounted on a symmetrical support mechanism. A sliding telescopic rod connects the bearing plate and the tension plate. The vertical plate is connected to the end of the bearing plate away from the tension plate and is perpendicular to the bearing plate. A magnetic adjustment mechanism is provided on the vertical plate.

[0006] Furthermore, the magnetic adjustment mechanism includes an adjustment cavity, an adjustment electromagnet, a switch, an adjustment conductor, and a hook. The adjustment cavity and the adjustment electromagnet are respectively disposed on a vertical plate. The adjustment cavity is hollow inside. The adjustment electromagnet is disposed on one side of the adjustment cavity, and the switch is disposed on the side of the adjustment electromagnet away from the adjustment cavity. The vertical plate is symmetrically provided with adjustment grooves, which are located below the adjustment cavity. The adjustment conductor is embedded in the adjustment groove on the side closer to the adjustment electromagnet. The hook is slidably disposed in the adjustment groove. A pressure spring is connected to the lower part of the hook, which is disposed in the adjustment groove. One side of the hook slides on the adjustment conductor. A drainage bag is suspended on the hook. A first connecting pipe connects the transition mechanism to the adjustment cavity, and a second connecting pipe connects the adjustment cavity to the drainage bag. A sliding conductor is embedded in the end of the hook near the adjustment conductor, and the sliding conductor slides on the adjustment conductor. The switch, the adjustment electromagnet, and the adjustment conductor are connected by wires to form a circuit. The adjustment electromagnet and the sliding conductor are connected by wires. The sliding conductor and the adjusting conductor form a sliding rheostat. Using a current-limiting connection, the resistance of the part of the adjusting conductor away from the adjusting electromagnet is connected to the circuit composed of the adjusting electromagnet and the switch. When the hook is pressed down, the resistance of the adjusting conductor connected to the circuit decreases, which increases the current flowing through the adjusting electromagnet.

[0007] Furthermore, the regulating cavity has a through hole on the side near the regulating electromagnet, and a sliding magnet is slidably mounted inside the regulating cavity. The magnetic poles of the sliding magnet and the regulating electromagnet are opposite. An adjusting spring is connected between the end of the sliding magnet away from the regulating electromagnet and the inner wall of the regulating cavity. A liquid passage hole is provided through the sliding magnet. In the initial state, the liquid passage hole is connected to the first connecting pipe and the second connecting pipe. After the drainage bag receives the ascites, the hook moves down under pressure, and the sliding conductor moves up and down in the adjusting conductor. The resistance of the adjusting conductor in the circuit decreases, allowing the fluid to flow through the adjusting conductor. As the current of the electromagnet increases, the magnetic poles of the regulating electromagnet and the sliding magnet become opposite. Under the action of magnetic repulsion, the sliding magnet overcomes the elastic force of the regulating spring and moves, causing the fluid inlet to deviate from the drainage channel of the first and second connecting tubes. Thus, without changing the shape of the catheter, the drainage speed is dynamically adjusted according to the amount of ascites in the patient's abdominal cavity during the ascites drainage process. When the ascites in the drainage bag reaches the maximum receiving capacity, the magnetic force of the regulating electromagnet reaches its maximum, and the sliding magnet completely closes the drainage channel of the first and second connecting tubes, stopping the drainage.

[0008] Furthermore, two sliding telescopic rods are symmetrically arranged, with the telescopic ends of the sliding telescopic rods connected to the tension plate. Positioning holes are evenly distributed through the sliding telescopic rods. Limiting grooves are evenly distributed on the upper wall of the bearing plate. Limiting frames are slidably arranged within the limiting grooves, and the limiting frames are arranged in an inverted C-shape. The first connecting pipe passes through the evenly distributed limiting frames, which are then slidably distributed, causing the first connecting pipe to conform to the bearing plate in a meandering manner, preventing it from being pulled or coming into contact with external bacterial environments during drainage. Insert blocks are respectively provided at the lower parts of the bearing plate and the tension plate.

[0009] Furthermore, the positioning mechanism includes a clamping rod, a clamping block, and a sliding support plate. The clamping rod is slidably sleeved on the telescopic end of a symmetrical sliding telescopic rod. There are two clamping rods. Positioning pins are installed at both ends of the clamping rods. The positioning pins are movably engaged with positioning holes. The clamping block is slidably disposed at the lower part of the clamping rod. The clamping block is arranged in a semi-circular ring shape. Magnetic blocks are provided on the opposite sidewalls of the two sets of clamping blocks. The two sets of magnetic blocks attract each other to make the two clamping blocks dock into a ring. The sliding support plate is horizontally disposed on the clamping block near the side of the bearing plate. The sliding support plate moves inside the bearing plate. Furthermore, the transition mechanism includes a transition bend, a rotating connecting pipe, and a collection box. The transition bend is installed on the upper part of the sliding support plate and is arranged in a Z-shape. The rotating connecting pipe is rotatably connected to the middle part of the transition bend. A drain valve is connected to the side wall of the rotating connecting pipe. The collection box is installed on the drain valve and is used to collect ascites samples.

[0010] Furthermore, the upper end of the puncture needle is connected to a puncture connecting tube, one end of the puncture connecting tube is connected to a transition bend tube, the other end of the transition bend tube is connected to a first connecting tube, and the upper end of the puncture needle is held by two sets of clamping blocks. Preferably, the outer side wall of the puncture needle is evenly distributed with grooves, which are arranged in a linear array along the axis of the puncture needle. The puncture needle is movably sleeved with a limiting cover, which is shaped like a frustum. The upper end of the limiting cover is evenly distributed with inclined limiting paddles, which are made of elastic plastic material. The upper end of the limiting paddles is movably engaged with the grooves. During use, the puncture depth is determined based on the ultrasound positioning results. The limiting cover is pushed down so that the distance from the lower end of the limiting cover to the tip of the puncture needle matches the puncture depth. The limiting tab on the limiting cover engages with the slot at that location, thus preventing the limiting cover from moving up. This makes it easier to determine the puncture needle insertion depth. When the puncture needle is inserted from the puncture point, the bottom of the limiting cover contacts the patient's skin, ensuring the vertical insertion of the puncture needle.

[0011] Furthermore, the support mechanism includes a base, a clamping and positioning plate, a clamping plate, and a support plate. The base is U-shaped, and a pressing plate is slidably provided inside the base. A threaded rod is rotatably provided at the lower part of the pressing plate, and the threaded rod is engaged with the base. The clamping and positioning plate is vertically mounted on the base, and a clamping screw is engaged with the center of the clamping and positioning plate. The clamping plate is rotatably mounted at the end of the clamping screw. A clamping pad made of sponge material is provided on the end face of the clamping plate. The support plate is located at the upper end of the clamping and positioning plate, and a locking groove is provided on the upper end face of the support plate. The insert block is movably engaged with the locking groove.

[0012] Preferably, the support mechanism is a sterile support structure, with the sterile end and the non-sterile end integrally formed or spliced ​​by a sterile process, with no gaps or contaminant residue channels at the connection. That is, the base and clamping positioning plate are non-sterile ends, and the support plate is sterile end, which is sterilized. The upper part of the clamping positioning plate is integrally connected to the support plate and has a protrusion at the connection to further prevent contaminants from the non-sterile end from contacting the sterile end. The pull-out bearing mechanism, positioning mechanism and transition mechanism are all sterilized before use.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows: 1. This invention provides a gastrointestinal ascites drainage device that utilizes electromagnetic principles combined with an assembled structure. It incorporates a magnetic adjustment mechanism, where a switch, an adjusting electromagnet, and an adjusting conductor are connected via wires to form a circuit. The adjusting electromagnet and a sliding conductor are connected via wires, forming a sliding rheostat. The resistance of the portion of the adjusting conductor furthest from the adjusting electromagnet is connected to the circuit formed by the adjusting electromagnet and the switch. When the hook is pressed down, the resistance of the adjusting conductor in the circuit decreases, increasing the current flowing through the adjusting electromagnet. This causes the sliding magnet to overcome the elastic force of the adjusting spring, moving the fluid inlet away from the flow channels of the first and second connecting pipes. Without altering the catheter's shape, the drainage speed is dynamically adjusted according to the amount of ascites in the patient's abdominal cavity during drainage. When the ascites decreases, the drainage speed is promptly reduced, and drainage is stopped when the drainage bag reaches a fixed drainage volume to avoid patient discomfort. 2. During ascites drainage, the drainage tube needs to be left in place at the puncture site in the patient's abdominal cavity for an extended period. The patient's position is fixed by a support mechanism, the position of the puncture needle is fixed by a positioning mechanism, and the first connecting tube, the second connecting tube, and the drainage bag are supported by a pull-out bearing mechanism. This allows the longer first connecting tube to be neatly concealed, preventing it from being pulled, squeezed, or exposed to external bacteria during drainage. This also prevents patient movement and catheter displacement or slippage, avoiding pain or bleeding caused by tube movement irritating the puncture site. At the same time, the vertical plate can fix the position of the drainage bag, keeping it in a low position to form a gravity drainage gradient and ensure smooth drainage. 3. The U-shaped transition mechanism facilitates observation of the drainage fluid's condition, and the collection box makes sampling easy, making operation convenient. Attached Figure Description

The upper part of the clamping positioning plate 42 is integrally connected to the support plate 46 and has a protrusion at its connection to further prevent contaminants from the non-sterile end from contacting the sterile end; the pull-out bearing mechanism 2, the positioning mechanism 3 and the transition mechanism 5 are all sterilized before use.

[0020] The pull-out bearing mechanism 2 includes a bearing plate 10 and a tension plate 11. The bearing plate 10 and the tension plate 11 are respectively mounted on a symmetrical support mechanism 1. The lower part of the bearing plate 10 and the tension plate 11 is provided with an insert block 16, which is movably engaged with the locking groove 47. A sliding telescopic rod 12 is connected between the bearing plate 10 and the tension plate 11. The sliding telescopic rod 12 is a telescopic structure, and two sliding telescopic rods 12 are symmetrically arranged. The telescopic end of the sliding telescopic rod 12 is connected to the tension plate 11. Positioning holes 13 are evenly distributed through the sliding telescopic rod 12. The upper wall of the bearing plate 10 is evenly distributed with limiting grooves 17. A limiting frame 18 is slidably arranged in the limiting groove 17. The limiting frame 18 is arranged in an inverted C shape. A vertical plate 21 is connected to the end of the bearing plate 10 away from the tension plate 11. The vertical plate 21 is perpendicular to the bearing plate 10. A magnetic adjustment mechanism 7 is provided on the vertical plate 21.

[0021] The magnetic adjustment mechanism 7 includes an adjustment cavity 30 and an adjustment electromagnet 31, which are respectively mounted on the vertical plate 21. The adjustment cavity 30 is hollow inside. The adjustment electromagnet 31 is located on one side of the adjustment cavity 30. A switch 32 is located on the side of the adjustment electromagnet 31 away from the adjustment cavity 30. Symmetrical adjustment grooves 33 are arranged on the vertical plate 21, located below the adjustment cavity 30. An adjustment conductor 36 is embedded in the adjustment groove 33 near the adjustment electromagnet 31. A hook 35 slides within the adjustment groove 33. A pressure spring 34 is connected to the lower part of the hook 35. 4. A hook 35 is located within the adjusting groove 33, and slides on the adjusting conductor 36. A drainage bag 9 is suspended on the hook 35. A first connecting pipe 6 connects the transition mechanism 5 and the adjusting cavity 30, and a second connecting pipe 8 connects the adjusting cavity 30 and the drainage bag 9. The first connecting pipe 6 passes through the evenly distributed limiting frame 18. Under the restriction of the limiting frame 18, the first connecting pipe 6 is meandering and fits against the support plate 10 to avoid being pulled or coming into contact with the external bacterial environment during drainage. A sliding conductor is embedded in the end of the hook 35 near the adjusting conductor 36, and the sliding conductor slides on the adjusting conductor 36. Switch 3 2. The regulating electromagnet 31 and the regulating conductor 36 are connected by a wire to form a circuit. The regulating electromagnet 31 and the sliding conductor are connected by a wire. The regulating cavity 30 has a through hole on the side near the regulating electromagnet 31. A sliding magnet 37 is slidably installed inside the regulating cavity 30. The magnetic poles of the sliding magnet 37 are opposite to those of the regulating electromagnet 31. An regulating spring 39 is connected between the end of the sliding magnet 37 away from the regulating electromagnet 31 and the inner wall of the regulating cavity 30. A liquid passage hole 38 is provided through the sliding magnet 37. In the initial state, the liquid passage hole 38 is connected to the first connecting pipe 6 and the second connecting pipe 8. The sliding conductor and the regulating... Conductor 36 forms a sliding rheostat. Using a current-limiting connection, the resistance of the part of the adjusting conductor 36 away from the adjusting electromagnet 31 is connected to the circuit composed of the adjusting electromagnet 31 and the switch 32. When the hook 35 is pressed down, the resistance of the adjusting conductor 36 in the circuit decreases, which increases the current flowing through the adjusting electromagnet 31. This causes the sliding magnet 37 to move against the elastic force of the adjusting spring 39, causing the fluid passage 38 to deviate from the flow channel of the first connecting pipe 6 and the second connecting pipe 8. Without changing the shape of the catheter, the drainage speed is dynamically adjusted according to the amount of ascites in the patient's abdominal cavity during the ascites drainage process.

[0022] The positioning mechanism 3 includes a clamping rod 14, which is slidably sleeved on the telescopic end of a symmetrical sliding telescopic rod 12. There are two clamping rods 14, and positioning pins 15 are installed at both ends of the clamping rod 14. The positioning pins 15 are movably engaged with the positioning holes 13. A clamping block 19 is slidably provided at the lower part of the clamping rod 14. The clamping block 19 is arranged in a semi-circular ring shape. Magnetic blocks are provided on the opposite side walls of the two sets of clamping blocks 19. The two sets of magnetic blocks attract each other to make the two clamping blocks 19 dock into a ring. A sliding support plate 20 is horizontally provided on the clamping block 19 near the support plate 10. The sliding support plate 20 moves inside the support plate 10.

[0023] The transition mechanism 5 includes a transition bend 22, which is installed on the upper part of the sliding support plate 20. The transition bend 22 is arranged in a Z-shape. A rotating connecting pipe 23 is rotatably connected to the middle part of the transition bend 22. A drain valve 24 is connected to the side wall of the rotating connecting pipe 23. A collection box 25 is installed on the drain valve 24.

[0024] The upper end of the puncture needle 4 is connected to a puncture connecting tube 29, which is connected to one end of a transition bend tube 22. The other end of the transition bend tube 22 is connected to a first connecting tube 6. The upper end of the puncture needle 4 is held by two sets of clamping blocks 19. The outer side wall of the puncture needle 4 is evenly distributed with slots 26, which are arranged in a linear array along the axis of the puncture needle 4. The puncture needle 4 is movably sleeved with a limit cover 27, which is shaped like a frustum. The upper end of the limit cover 27 is evenly distributed with inclined limit paddles 28, which are made of elastic plastic. The upper end of the limit paddles 28 is movably engaged with the slots 26. The bottom surface of the limit cover 27 is perpendicular to the axis of the puncture needle 4.

[0025] Working principle and workflow: In practical use, medical staff instruct the patient to lie on the hospital bed with the abdominal cavity exposed. After placing a disposable sheet, the puncture point is exposed. Two sets of support mechanisms 1 are taken out, and the base 40 is inserted into the hospital bed through the edge of the sheet. The threaded rod is turned so that the compression plate 41 moves upward inside the base 40 until the two sets of support mechanisms 1 are clamped on the hospital bed, with the clamping plates 43 on the two sets of support mechanisms 1 facing each other. Then, the clamping screw 45 is turned so that the opposing clamping plates 43 move closer to the sides of the patient's abdominal cavity until the patient's abdominal cavity is clamped. The clamping pad 44 adapts to deform and fits the sides of the patient's abdominal cavity to prevent the patient from moving during the drainage process.

[0026] Medical staff remove the pull-out support mechanism 2, align the insert 16 with the slot 47, and install the support plate 10 and tension plate 11. The sliding telescopic rod 12 extends and retracts adaptively. During this process, the vertical plate 21 is outside the bed. Then, the new transition mechanism 5 is removed, and the transition bend 22 is inserted into the sliding support plate 20. The drain valve 24 is checked to be in the closed state. At this time, the collection box 25 is on one side of the transition bend 22. The two clamping rods 14 are far apart from each other, and the patient's puncture site is between the two clamping rods 14. After disinfecting the patient's puncture site, a sterile drape is placed, and local anesthesia is administered. While waiting for the anesthesia to take effect, the first connecting tube 6 is inserted through the evenly distributed limiting frames 18. The limiting frames 18 are pushed, sliding within the limiting grooves 17, causing them to be staggered. This makes the first connecting tube 6 meander close to the support plate 10, preventing the longer tube from being pulled, squeezed, or exposed to external bacteria during drainage. The two ends of the first connecting tube 6 are connected between the transition bend 22 and the adjustment chamber 30, respectively. The second connecting tube 8 is then connected... Connect to the lower part of the adjustment chamber 30, take out the drainage bag 9 and connect it to the second connecting tube 8, and hang the drainage bag 9 on the hook 35; then take out the puncture needle 4, determine the puncture depth according to the ultrasound positioning result, push the limiting cover 27 down so that the distance from the lower end face of the limiting cover 27 to the tip of the puncture needle 4 matches the puncture depth, the limiting tab 28 on the limiting cover 27 engages with the slot 26 at that location, thereby preventing the limiting cover 27 from moving up, and then connect the puncture connecting tube 29 to the end of the transition bend tube 22.

[0027] After the anesthesia takes effect for 1-2 minutes, push the clamping rod 14 on one side of the transition bend 22 to the puncture point. The sliding support plate 20 moves adaptively within the support plate 10, aligning the puncture needle 4 with the puncture point and inserting it until the bottom of the limiting cover 27 contacts the patient's skin, ensuring the vertical insertion of the puncture needle 4. Due to the intra-abdominal pressure and the height difference between the drainage bag 9 and the patient's body position, ascites flows into the drainage bag 9 through the puncture needle 4, puncture connecting tube 29, transition bend 22, first connecting tube 6, adjustment chamber 30, and second connecting tube 8. Immediately afterwards, fix the puncture needle 4, push the two clamping rods 14, and slide the clamping block 19 so that the two clamping blocks 19 close and clamp the upper end of the puncture needle 4. Then, fix the position of the two clamping rods 14 by the positioning pin 15. Finally, turn on the switch 32.

[0028] After the drainage bag 9 receives the ascites, the hook 35 is pressed down, and the sliding conductor moves up and down on the adjusting conductor 36. The resistance of the adjusting conductor 36 in the circuit decreases, which increases the current flowing through the adjusting electromagnet 31. The magnetic poles of the adjusting electromagnet 31 and the sliding magnet 37 are opposite. Under the action of magnetic repulsion, the sliding magnet 37 moves against the elastic force of the adjusting spring 39, causing the fluid passage 38 to deviate from the guide channel of the first connecting tube 6 and the second connecting tube 8. Thus, without changing the shape of the catheter, the drainage speed is dynamically adjusted according to the amount of ascites in the patient's abdominal cavity during the ascites drainage process. When the ascites in the drainage bag 9 reaches the maximum receiving capacity, the magnetic force of the adjusting electromagnet 31 reaches its maximum, and the sliding magnet 37 completely seals the guide channel of the first connecting tube 6 and the second connecting tube 8, stopping the drainage and waiting for staff to handle it.

[0029] During the drainage process, the state of the ascites can be observed through the transparent transition bend 22. If it is necessary to collect an ascites sample, simply open the drain valve 24 to allow the ascites to flow into the collection box 25 and then close the drain valve 24. If the ascites is collected at the beginning of the drainage, the connecting tube 23 can be turned so that the collection box 25 faces upwards, making it easier to compare and observe the changes in the state of the ascites during the drainage process.

[0030] After drainage is completed, remove the drainage bag 9 and connect the second connecting tube 8 to the waste bag. Remove the positioning pin 15, open the two clamping rods 14, press the puncture point with sterile gauze, pull out the puncture needle 4, press the puncture point for 5-10 minutes, disinfect and bandage, and monitor postoperative vital signs. Then, retrieve the puncture needle 4, transition mechanism 5, first connecting tube 6 and second connecting tube 8, remove the pull-out bearing mechanism 2 and clean and sterilize it. At the same time, loosen the clamping screw 45 and the threaded rod respectively, and remove the support mechanism 1.

[0031] It is worth noting that the collection box 25 uses a transparent box with a fixed capacity. The use of a sterile support structure and the sterilization technology of medical devices are existing technologies and will not be elaborated here.

[0032] The above is the overall workflow of this invention. Simply repeat this process the next time you use it.
