Description

Technical Field

[0001] This invention relates to the field of gastrointestinal drainage technology, and more particularly to a drainage device for gastrointestinal surgery. Background Technology

[0002] A drainage device is used to drain fluid, gas, or infectious substances from a patient's body, thereby reducing pressure within the body. It is commonly used in cases of intestinal obstruction, postoperative ileus, and other conditions. Common gastrointestinal surgical drainage devices are mainly divided into passive drainage devices and active drainage devices. Active drainage devices rely on negative pressure suction for active drainage.

[0003] During the drainage of a patient's gastrointestinal tract, the aspirated material may contain food residue, blood clots, or mucus. These materials can easily accumulate in the drainage tube, leading to blockage. Additionally, if the patient ingests medications such as magnesium aluminum carbonate or sucralfate, these medications can react with gastrointestinal fluids to form a viscous gel. This gel can deposit in the drainage tube, further increasing the risk of blockage. Once the drainage tube is blocked, the drainage process cannot proceed smoothly, impurities in the patient's body cannot be expelled in time, causing distension of the gastrointestinal lumen and irritation of visceral nerves.

[0004] After the drainage tube becomes blocked, 20-30 ml of normal saline is usually used to quickly flush the drainage tube, followed by gentle aspiration. This process is repeated several times to loosen the adhesions using the force of the liquid. However, if the flushing fluid is not effectively drained during the flushing process, it can lead to increased pressure in the gastrointestinal tract, aggravating the patient's discomfort or causing other complications. At the same time, high-pressure flushing can cause damage to the gastric mucosa, and may even cause bleeding or perforation. If high-pressure flushing cannot relieve the blockage, it will delay further treatment measures, thereby affecting the treatment effect. Summary of the Invention

[0005] In order to overcome the shortcomings described in the background art, the present invention provides a drainage device for gastrointestinal surgery.

[0006] The technical embodiment of the present invention is as follows: a drainage device for gastrointestinal surgery, comprising a housing, an absorbent bladder installed inside the housing, a pressing plate slidably connected inside the housing, and a first elastic element disposed between the two, the pressing plate being fixedly connected to the absorbent bladder, the absorbent bladder being fixedly connected to and connected to a first catheter, a first one-way valve being installed inside the first catheter, a second catheter being fixedly connected inside the housing, the second catheter being connected to the first catheter, and a drainage tube located outside the housing being fixedly connected to and connected to the second catheter, further comprising:

[0007] A traction rope is disposed inside the outer casing and located inside the second conduit. One end of the traction rope is fixedly connected to a cleaning component, which is located inside the drainage tube of the second conduit.

[0008] A winding and rotating mechanism, disposed within the housing, is used to wind up the traction rope and drive the cleaning component to rotate;

[0009] A drive mechanism, located inside the housing, is used to move the traction rope, causing the cleaning component to move to the area to be cleaned. The cleaning component rotates within the second conduit, thereby cleaning the impurities within the second conduit.

[0010] As a further preferred embodiment, the cleaning component is elastic and consists of several interlaced spiral sections and several straight connecting sections. The drainage tube of the second conduit is provided with several expansion cavities, and the expansion cavities of the drainage tube correspond one-to-one with the spiral sections of the cleaning component.

[0011] As a further preferred embodiment, the winding rotation mechanism includes:

[0012] The mounting housing is slidably connected inside the outer shell, and the mounting housing is slidably connected to the traction rope;

[0013] A winding component is rotatably connected to the mounting housing, and the winding component is fixedly connected to the other end of the traction rope;

[0014] A locking component, disposed on the mounting housing, is used to secure the traction rope.

[0015] As a further preferred embodiment, the outer shell is slidably connected to a first locking block, and a second elastic element is disposed between the two. The first locking block penetrates through the mounting shell and is used to limit the winding component of the mounting shell.

[0016] As a further preferred embodiment, the locking component includes:

[0017] A rotating ring is rotatably connected inside the mounting housing, and the traction rope passes through the rotating ring;

[0018] The second locking block is slidably connected to the rotating ring, and a third elastic element is provided between the two. The second locking block is slidably connected to the winding component and is used to fix the traction rope.

[0019] As a further preferred embodiment, the drive mechanism includes:

[0020] A joystick, which is rotatably and slidably connected to the housing;

[0021] A sliding sleeve is slidably connected to the rocker arm;

[0022] There are several rotating wheels, all rotatably connected inside the mounting housing. The traction rope is located between all the rotating wheels. The sliding sleeve is fixedly connected to one of the rotating wheels. Several friction wheels are rotatably connected to the rotating wheels, and the friction wheels are in pressure contact with the traction rope.

[0023] As a further preferred embodiment, the outer shell is fixedly connected to a first limiting ring, and the rocker arm is fixedly connected to a second limiting ring, wherein the first limiting ring is used to limit the second limiting ring.

[0024] As a further preferred embodiment, both the first limiting ring and the second limiting ring have toothed protrusions on their opposite sides.

[0025] As a further preferred embodiment, the device also includes an adsorption element, wherein a reflux channel is provided inside the outer shell, the reflux channel is connected to the absorption bladder, the adsorption element is installed on the outer shell and located inside the reflux channel, and a second one-way valve is installed at the connection between the reflux channel and the absorption bladder.

[0026] As a further preferred embodiment, it also includes a transition ring and a sealing element, the transition ring being connected to the first conduit, and the sealing element being slidably connected to the outer shell, the sealing element being used to block the transition ring.

[0027] This invention has the following advantages: The rotating cleaning component gradually extends into the impurities, dispersing them and reducing the area of ​​blockage on the drainage tube, thus ensuring normal operation of the drainage tube. This process avoids drastic pressure changes within the patient's body, reducing secondary harm. The timed reciprocating movement of the cleaning component scrapes the inner wall of the drainage tube, effectively cleaning it. The spiral design of the cleaning component applies a pushing force to the impurities and fixes those that are difficult to disperse, facilitating their removal and ensuring efficient cleaning of the drainage tube. The elastic setting of the cleaning component allows it to adapt to changes in the drainage tube during its movement, reducing the rigid pressure on the tube. The adsorption component filters the flowing gas, adsorbing bacteria and other harmful substances, preventing direct discharge into the external environment and contamination of the operating room or ward air, thereby reducing occupational exposure risks for medical staff and the chance of cross-infection for patients.

Detailed Implementation

[0040] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting" and "installation" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances. Example

[0041] This embodiment discloses a drainage device for gastrointestinal surgery, used to drain gas, liquid or solid contents (hereinafter referred to as impurities) from the patient's gastrointestinal tract.

[0042] Combination Figures 1-5As shown, the device includes a housing 1; an absorbent bladder 2 installed inside the housing 1, with a pressing plate 3 slidably connected inside the housing 1, and a first elastic element, which is a tension spring, between the two for resetting the pressing plate 3; the pressing plate 3 is fixedly connected to the absorbent bladder 2; a first conduit 4 fixedly connected to and connected to the absorbent bladder 2, with a first one-way valve installed inside it; this first one-way valve only allows impurities in the first conduit 4 to be discharged into the absorbent bladder 2, but does not allow impurities in the absorbent bladder 2 to enter the first conduit 4; a second conduit 5 fixedly connected inside the housing 1, communicating with the first conduit 4, and a [missing information - likely a device or component] fixedly connected to and connected to the second conduit 5. A drainage tube is located outside the outer shell 1. The drainage tube is inserted into the patient's body and connected to the second catheter 5. By pulling the pressing plate 3 upward, the gas in the absorption bag 2 is discharged. Then, under the action of the first elastic element on the pressing plate 3, the absorption bag 2 returns to its original shape, and a negative pressure is formed inside the absorption bag 2. The absorption bag 2 uses its internal negative pressure to drain impurities from the patient's body through the first catheter 4, the second catheter 5 and the drainage tube. In this embodiment, a gas collection device is connected to the upper side of the absorption bag 2 to absorb the gas discharged from the absorption bag 2 and prevent the gas from diffusing into the outside air.

[0043] The specific structure and connection relationships of each component are as follows:

[0044] 1. Towing rope 6 and cleaning components 7

[0045] Combination Figures 1-5 As shown, the traction rope 6 is located inside the second catheter 5. The traction rope 6 is made of steel wire rope (medical grade). The cleaning component 7 is located inside the drainage tube of the second catheter 5. The cleaning component 7 is fixedly connected to the traction rope 6. The cleaning component 7 consists of several spiral parts and several straight connecting parts. The spiral parts and straight connecting parts of the cleaning component 7 are interlaced. The spiral parts of the cleaning component 7 are used to guide the contacted impurities, which is conducive to the discharge of impurities. The maximum diameter of the spiral part of the cleaning component 7 is equal to the minimum inner diameter of the drainage tube. The cleaning component 7 is elastic, allowing it to bend under elastic action. The drainage tube of the second catheter 5 is provided with a dilation cavity (such as...). Figure 5 When the drainage tube is working normally, the cleaning part 7 is located in the expansion cavity to avoid obstructing the drainage work. The expansion cavity of the drainage tube corresponds one-to-one with the spiral part of the cleaning part 7.

[0046] The above setup enables the cleaning component 7 to be moved to the blockage location of the drainage tube by the traction rope 6 after the drainage tube is blocked. The rotation and reciprocating movement of the cleaning component 7 guides the impurities accumulated in the drainage tube, allowing the impurities to be discharged. The elasticity of the cleaning component 7 makes it easy to adapt to the bending of the drainage tube.

[0047] 2. A winding and rotating mechanism, located inside the outer casing 1, is used to wind up the traction rope 6 and drive the cleaning component 7 to rotate.

[0048] Combination Figures 1-3 , Figure 6 and Figure 7 As shown, the winding and rotating mechanism includes: a mounting shell 21, which is slidably connected inside the outer shell 1; the mounting shell 21 is slidably connected to the traction rope 6; and a flexible sealing ring (such as...) is provided at the sliding connection between the two. Figure 8 The flexible sealing ring is used to prevent impurities flowing inside the second conduit 5 from entering the mounting housing 21, and can also scrape the surface of the traction rope 6 to reduce the amount of impurities adhering to it entering the mounting housing 21; the winding member 22 is rotatably connected to the mounting housing 21, and the winding member 22 is fixed to the other end of the traction rope 6. The winding member 22 is composed of a crank, a circular plate, a cylinder, a circular shell, and L-shaped rods distributed circumferentially (e.g., Figure 6 The L-shaped rod is located between the circular plate and the circular shell, the circular plate is located between the crank handle and the cylinder, and there is a gap between the L-shaped rod and the cylinder. The thickness of the gap is the same as the diameter of the traction rope 6. The traction rope 6 is wound around the cylinder. The locking assembly is set on the mounting shell 21 and is used to fix the traction rope 6.

[0049] Combination Figure 3 , Figure 6 and Figure 7 As shown, the outer shell 1 is slidably connected to a first locking block 31, and a second elastic element, which is a spring, is provided between the two to drive the first locking block 31 to reset and maintain the limiting position of the mounting shell 21 and the winding member 22. The first locking block 31 penetrates the mounting shell 21. The lower side of the first locking block 31 is provided with an inclined surface facing forward. The upper side of the first locking block 31 is provided with evenly distributed protrusions. The first locking block 31 is used to limit the mounting shell 21 and the winding member 22.

[0050] Combination Figures 6-9 As shown, the locking assembly includes: a rotating ring 41, rotatably connected to the mounting housing 21, through which the traction rope 6 passes; a second locking block 42, slidably connected to the rotating ring 41, with a third elastic element (a spring) between them, used to reset the second locking block 42, preventing it from contacting the traction rope 6. The second locking block 42 is slidably connected to the winding member 22, and is used to fix the traction rope 6. In this embodiment, the third locking block 42 has four circumferentially evenly distributed (e.g., Figure 9 All the opposite sides of the second locking blocks 42 are made of rough surfaces to increase their friction with the traction rope 6. All the back sides of the second locking blocks 42 are made of inclined surfaces. The inclined surfaces of the second locking blocks 42 slide along the winding member 22. The winding member 22 can drive the rotating ring 41 to rotate through the second locking blocks 42.

[0051] The above settings allow the following: when the drainage tube needs to be cleaned with the cleaning component 7, the winding component 22 is pressed backward. The winding component 22 squeezes all the second locking blocks 42, and all the second locking blocks 42 move in opposite directions and clamp the traction rope 6. At this time, the second locking blocks 42 and the traction rope 6 cannot move relative to each other, and the traction rope 6 and the winding component 22 form a "whole". Then, by turning the handle of the winding component 22, the winding component 22 drives the traction rope 6 to rotate synchronously through all the second locking blocks 42, thus achieving the purpose of guiding the impurities to be cleaned.

[0052] After cleaning, the operator must perform the following steps in sequence: First, pull the first locking block 31 upward to release the limit on the winding component 22; then pull the winding component 22 forward to reset it, at which point the second locking block 42 disengages from the traction rope 6; finally, the operator rotates the winding component 22 to complete the winding of the traction rope 6.

[0053] 3. Drive mechanism, located inside housing 1, is used to move the traction rope 6, thereby moving the cleaning component 7 to the area to be cleaned.

[0054] Combination Figure 2 and Figures 8-10 As shown, the driving mechanism includes: a rocker arm 51, which is rotatably and slidably connected to the outer casing 1; a sliding sleeve 52, which is slidably connected to the rocker arm 51 and located inside the outer casing 1; and two symmetrically distributed rotating wheels 53, both rotatably connected to the mounting housing 21. The rotating wheels 53 are located behind the rotating ring 41, and the traction rope 6 is located between the symmetrically distributed rotating wheels 53. The sliding sleeve 52 is fixedly connected to one of the rotating wheels 53. Several friction wheels 54 are rotatably connected to the rotating wheel 53. The friction wheels 54 are in contact with the traction rope 6. The central axis of the friction wheel 54 and the central axis of the rotating wheel 53 are perpendicular skew lines. A rubber layer is provided on the outer side of the friction wheel 54. The rotating wheel 53 drives all the friction wheels 54 on it to rotate, thereby causing the traction rope 6 to slide inside the second guide tube 5, thereby driving the cleaning component 7 to move.

[0055] Combination Figure 8 and Figure 9 As shown, the outer casing 1 is fixedly connected to a first limiting ring 61, and the rocker arm 51 passes through the first limiting ring 61. The rocker arm 51 is fixedly connected to a second limiting ring 62. The first limiting ring 61 is used to limit the second limiting ring 62. By limiting the second limiting ring 62 with the first limiting ring 61, the rocker arm 51 cannot move, thereby making the traction rope 6 stable after moving to the target position. The opposing sides of the first limiting ring 61 and the second limiting ring 62 are provided with toothed protrusions, which are used to increase the contact area of ​​the first limiting ring 61 and the second limiting ring 62.

[0056] The working process of the gastrointestinal surgical drainage device in this embodiment is as follows:

[0057] Traffic generation preparation:

[0058] First, insert the cleaning component 7 into the drainage tube of the second catheter 5, ensuring that the spiral part of the cleaning component 7 corresponds one-to-one with the expansion chamber of the drainage tube. Then, connect the second catheter 5 to the drainage tube and the cleaning component 7 to the traction rope 6. Subsequently, insert the drainage tube into the patient's body. As the drainage tube is gradually inserted, stop moving the drainage tube when the end of the drainage tube moves to the patient's drainage site. At this point, the drainage preparation is complete.

[0059] Traffic generation begins:

[0060] The operator pulls the pressure plate 3 upwards, which compresses the absorption bag 2 (stretching the first elastic element of the pressure plate 3). The absorption bag 2 is compressed, and the gas inside is discharged into the external gas collection device. After the pressure plate 3 is moved upwards to its limit position (it cannot be moved upwards any further), the operator stops pulling the pressure plate 3 upwards and holds the pressure plate 3 downwards (the first elastic element of the pressure plate 3 gradually shortens). The absorption bag 2 gradually returns to its original shape. The absorption bag 2 uses its own negative pressure to extract impurities through the first catheter 4, the second catheter 5, and the drainage tube. The impurities enter the absorption bag 2 along the drainage tube, the second catheter 5, and the first catheter 4. As the pressure plate 3 moves downwards until it returns to its initial position, the single extraction of impurities is completed. The operator then repeats the above process to drain impurities from the patient's body.

[0061] Drainage interruption:

[0062] As the pressing plate 3 moves up and down repeatedly, impurities gradually enter the absorption bladder 2. During the process of the impurities passing through the drainage tube, they will accumulate inside the drainage tube, which will cause the drainage tube to become blocked. After the drainage tube is blocked, the pressing plate 3 continues to move up and down. At this time, a negative pressure will be formed on the part of the drainage tube from the blockage point to the second conduit 5, causing the drainage tube in this part to be compressed and flattened. At the same time, the moving resistance of the pressing plate 3 will gradually increase. After the operator perceives the abnormality, he / she stops moving the pressing plate 3 and stops the drainage operation.

[0063] After stopping the movement of the pressing plate 3, the operator begins to turn the rocker arm 51 clockwise (to... Figure 1 (From the left-middle view perspective), the rocker arm 51 drives the upper rotating wheel 53 to rotate through the sliding sleeve 52. The upper rotating wheel 53 drives all the friction wheels 54 on it to rotate clockwise in a circumferential direction. The friction wheels 54 drive the traction rope 6 to move backward through their own friction, and the traction rope 6 drives the cleaning component 7 to move.

[0064] During the movement of the cleaning component 7, the spiral part of the cleaning component 7 scrapes against the inner wall of the drainage tube, scraping off the impurities attached to the inner wall of the drainage tube. As the cleaning component 7 gradually moves until it can no longer move, that is, when the cleaning component 7 has moved to the blockage position, the operator stops turning the rocker arm 51 and pushes the rocker arm 51 to the left, so that the rocker arm 51 moves relative to the sliding sleeve 52. The rocker arm 51 drives the second limiting ring 62 to move until the second limiting ring 62 contacts the first limiting ring 61. Then, the operator stops pushing the rocker arm 51. At this time, with the cooperation of the second limiting ring 62 and the first limiting ring 61, the rocker arm 51 cannot rotate freely, that is, the traction rope 6 will not be displaced.

[0065] After stopping the rocker arm 51, the operator pushes the take-up piece 22 backward. The circular plate of the take-up piece 22 presses against the first locking block 31. The first locking block 31 moves upward and compresses its second elastic element until the circular plate of the take-up piece 22 passes the first locking block 31. Then, the first locking block 31 moves downward under the action of its second elastic element and limits the take-up piece 22. At this time, the push of the take-up piece 22 is stopped.

[0066] As the winding component 22 moves backward, the round shell of the winding component 22 squeezes all the second clamping blocks 42, causing all the second clamping blocks 42 to move in opposite directions and compress the third elastic element on them, until the winding component 22 stops moving. At this time, all the second clamping blocks 42 clamp the traction rope 6, and the traction rope 6 and the winding component 22 form a "whole".

[0067] After the second clamping block 42 clamps the traction rope 6, the operator rotates the winding component 22 clockwise. At this time, the winding component 22 drives the traction rope 6 to rotate synchronously through all the second clamping blocks 42. The traction rope 6 drives all the friction wheels 54 to rotate, and the traction rope 6 drives the cleaning component 7 to rotate. During the rotation of the cleaning component 7, according to its own spiral design, the spiral part at the end of the cleaning component 7 gradually extends into the impurities. Since the traction rope 6 cannot move, the spiral part at the end of the cleaning component 7 is gradually stretched, which promotes the dispersion of impurities and causes the impurities to lose their influence on the drainage pipe. During the rotation of the cleaning component 7, the spiral part of the cleaning component 7 applies a forward force to the impurities, facilitating their movement. As the cleaning component 7 rotates, the internal pressure of the drainage tube returns to normal, and the drainage tube returns to its initial state. Subsequently, the pressing plate 3 continues to move under the action of the first elastic element, and the impurities in the patient's body continue to flow into the absorption bag 2 through the drainage tube, the second catheter 5, and the first catheter 4. The absorption bag 2 continues to drain the impurities from the patient's body. At this time, the operator stops rotating the winding component 22.

[0068] Traffic generation continues:

[0069] After stopping the rotation of the take-up member 22, pull the rocker arm 51 to the right to make the second limiting ring 62 lose contact with the first limiting ring 61. Then pull the first locking block 31 upward (the second elastic element on it is compressed) until the take-up member 22 can pass through the first locking block 31. Then stop pulling the first locking block 31 and pull the take-up member 22 forward. After the circular plate of the take-up member 22 passes the first locking block 31, release the first locking block 31 and stop pulling the take-up member 22.

[0070] After the winding component 22 moves forward, the round shell of the winding component 22 loses its pressure on all the second locking blocks 42. The second locking blocks 42 reset under the action of the third elastic element on them and lose contact with the traction rope 6. Then the operator rotates the winding component 22 clockwise again, and the winding component 22 begins to wind up the traction rope 6. The traction rope 6 moves relative to all the friction wheels 54. During the winding process, the traction rope 6 drives the cleaning component 7 to move forward. When the spiral part of the cleaning component 7 moves into the expansion cavity of the drainage tube initially corresponding to it, the operator stops rotating the winding component 22. During the movement of the cleaning component 7, it drives the impurities forward. At the same time, the impurities flowing in the drainage tube also push the impurities at the blockage to move until all impurities enter the absorption bladder 2, and then the cleaning operation of the drainage tube is stopped.

[0071] The above operation is mainly for the treatment of blockage in the drainage tube. During the drainage operation, the operator rotates the rocker arm 51 back and forth at regular intervals. The rocker arm 51 drives the traction rope 6 to move back and forth through the friction wheel 54. The traction rope 6 drives the cleaning component 7 to move back and forth. During the process, the spiral part of the cleaning component 7 moves back and forth to scrape the inner wall of the drainage tube, thereby scraping away the impurities attached to the inside of the drainage tube, thus ensuring the normal use of the drainage tube.

[0072] Traffic generation complete:

[0073] After draining impurities from the patient's body, the operator removes and replaces the absorption bag 2, removes the drainage tube from the patient's body, disconnects the second catheter 5 from the drainage tube, and disconnects the cleaning component 7 from the traction rope 6. The operator then pulls the first locking block 31 upwards, causing it to move upwards and compress the second elastic element on it. Pulling the first locking block 31 stops once it loses contact with the mounting shell 21. Simultaneously, the operator pulls the winding component 22 forward, causing it to move synchronously with the mounting shell 21, winding it up. The cleaning component 22 moves synchronously with the traction rope 6 until the traction rope 6 that needs to be cleaned is removed from the outer casing 1. The operator then cleans the cleaning component 7 and the traction rope 6. Since not all the traction ropes 6 wrapped around the winding component 22 participate in the unblocking of the drainage pipe, it is not necessary to clean all the traction ropes 6. After cleaning, the above operation is repeated in reverse to install the mounting shell 21 into the outer casing 1. The mounting shell 21 then moves the winding component 22 and the traction rope 6 into the outer casing 1 synchronously, ending the use of this device. At this point, the drainage operation is complete. Example

[0074] This embodiment discloses a drainage device for gastrointestinal surgery. Based on embodiment 1, it also has the function of treating the gas discharged from the absorption bag 2. The waste gas recovery device in embodiment 1 is replaced by the following scheme.

[0075] Existing drainage devices require external waste gas recovery equipment to assist in the operation of the discharged gas. However, the waste gas recovery equipment (such as gas collection bags) can only temporarily store the gas, and subsequent gas treatment is required. This process is cumbersome, and if the sealing is not in place during gas transfer, gas may escape, increasing the risk of infection.

[0076] Combination Figures 2-4 As shown, it also includes a reflux channel 71 and an adsorption element 72.

[0077] 1. Return channel 71

[0078] Combination Figure 3 and Figure 4 As shown, the reflux channel 71 is disposed inside the outer shell 1. The front side of the reflux channel 71 is connected to the absorption bladder 2, and the rear side of the reflux channel 71 is connected to the outside. The reflux channel 71 is used to guide the gas discharged from the absorption bladder 2 to the outside.

[0079] 2. Adsorption component 72

[0080] Combination Figure 2 and Figure 4As shown, the adsorbent 72 is detachably installed on the outer shell 1 and located in the return channel 71. The adsorbent 72 contains adsorbent particles such as activated carbon. The adsorbent 72 filters the gas flowing through the return channel 71, adsorbing particulate matter, bacteria and other harmful substances in the gas, preventing the gas from being directly discharged into the external environment and polluting the air in the operating room or ward. This reduces the occupational exposure risk of medical staff and the chance of cross-infection of patients. A second one-way valve is installed at the connection between the return channel 71 and the absorption bag 2. This second one-way valve is used to allow the gas in the absorption bag 2 to enter the return channel 71, but it cannot allow the gas in the return channel 71 to flow back into the absorption bag 2. The operator can replace the adsorbent 72 periodically to ensure the filtration effect of the gas.

[0081] 3. Transition ring 81 and sealing component 82

[0082] Combination Figures 2-4 and Figure 11 As shown, the transition ring 81 is located in the middle of the first conduit 4, cutting off the first conduit 4 and connecting with it. The sealing member 82 is slidably connected to the outer shell 1, and the sealing member 82 slides on the transition ring 81, thereby blocking the transition ring 81. This achieves the blocking of the first conduit 4, thereby adjusting the flow area of ​​the first conduit 4 and controlling the flow of impurities within it. A flexible membrane (such as...) is provided between the sealing member 82 and the transition ring 81. Figure 11 The flexible membrane is used to seal the sliding connection between the sealing element 82 and the transition ring 81, preventing impurities flowing through the transition ring 81 from escaping.

[0083] The above settings enable the operator to adjust the position of the occluder 82 appropriately according to the patient's physical condition during gastrointestinal drainage, so that the occluder 82 blocks the flow surface of the transition ring 81, changes the flow area of ​​the occluder 82, thereby adjusting the flow rate of impurities in the first catheter 4, so that the impurities are discharged at a rate that the patient can tolerate, and reduces the patient's discomfort.
