[0024] Please refer to Figures 1 - 8 In this embodiment, a peritoneal drainage tube with anti-leakage function is provided, which includes: a drainage assembly 1, the drainage assembly 1 includes a drainage main tube 102 and a liquid guiding head 101, and the liquid guiding head 101 is detachably arranged on the drainage main tube 102; an anti-leakage assembly 2, the anti-leakage assembly 2 includes an annular airbag 201, an air charging pipeline 202 and an air charging head 203, the annular airbag 201 is arranged on the drainage main tube 102, both ends of the air charging pipeline 202 are respectively communicated with the air charging head 203 and the annular airbag 201, the air charging pipeline 202 is located inside the drainage main tube 102, and one end of the air charging pipeline 202 away from the annular airbag 201 extends out of the drainage main tube 102, and the air charging head 203 is used to connect an external air charging device; a limiting assembly 3, the limiting assembly 3 includes a chuck 301 slidably arranged on the drainage main tube 102 and a limiting member 302, the limiting member 302 is arranged on the chuck 301, and the chuck 301 can cooperate with the annular airbag 201 to generate a radial clamping force to clamp the abdominal wall tissue.

[0025] In this embodiment, the above-mentioned drainage assembly 1 is used to drain and export abnormal fluid in the abdominal cavity after surgery, so as to reduce the pressure in the abdominal cavity, prevent infection and promote wound healing. Specifically, the above-mentioned drainage main tube 102 is used to directly divert the abnormal fluid in the abdominal cavity, so as to facilitate its transportation to the drainage bag, and medical staff can observe the patient's condition according to the state of the abnormal fluid, so as to formulate corresponding treatment measures. The above-mentioned liquid guiding head 101 is used to lead out the fluid in the abdominal cavity, and the liquid guiding head 101 is used as an outlet to export the liquid fluid.

[0026] In this embodiment, the above-mentioned anti-leakage assembly 2 is used to form an airbag behind the human abdominal cavity, and then pull the drainage main tube 102 to make it abut against the inner wall of the abdominal cavity, so as to avoid the abnormal fluid in the abdominal cavity from overflowing through the gap between the drainage main tube 102 and the human abdomen by flexible abutment. Specifically, the above-mentioned annular airbag 201 is used to form a flexible disc structure after extending into the abdominal cavity. Pulling the drainage main tube 102 outwards can make the disc structure abut against the inner wall of the abdominal tissue. Under the interaction of the abdominal tissue and the disc structure, the leakage of fluid can be avoided, resulting in skin irritation, injury and wound infection. The above-mentioned air charging pipeline 202 is used to transport the gas for filling the annular airbag 201, and the above-mentioned air charging head 203 is used to connect with an air charging device, so as to quickly and efficiently fill the annular airbag 201.

[0027] In this embodiment, the above-mentioned limiting component 3 is used to cooperate with the anti-leakage component 2 to fix the entire anti-leakage abdominal drainage tube. First, the annular airbag 201 in the contracted state is inserted into the human abdominal cavity, and then after being filled, it is pulled outwards and abutted against the inner wall of the human abdominal cavity. By pushing the limiting component 3 towards the outer wall of the human abdomen, after the limiting component 3 is fixed, the entire anti-leakage abdominal drainage tube is fixed. The whole process does not require tape bonding and can adapt to people with different abdominal tissue thicknesses, improving the applicable range of the anti-leakage abdominal drainage tube.

[0028] Specifically, the above-mentioned chuck 301 is used to cooperate with the annular airbag 201 to limit and clamp the patient's abdominal tissue in the radial direction of the drainage pipeline. The clamping distance can be adjusted according to the thickness of the patient's abdominal tissue, so as to effectively expand the applicable range of the entire device. The above-mentioned limiting member 302 is used to fix the chuck 301 on the main drainage tube 102. Medical staff can adjust the position of the chuck 301 according to the patient's comfort, improving the patient's comfort.

[0029] Please refer to Figure 2 , in some embodiments of this embodiment, a threaded head 4 is provided on the above-mentioned liquid guiding head 101, and an internal thread is provided at one end of the main drainage tube 102 close to the liquid guiding head 101. The threaded head 4 is in threaded connection with the internal thread, and the outer diameter of the main drainage tube 102 is the same as the outer diameter of the liquid guiding head 101.

[0030] In this embodiment, the above-mentioned liquid guiding head 101 and the main drainage tube 102 are detachably connected by a threaded connection, which is convenient for medical staff to select the length of the liquid guiding head 101 according to the drainage position, avoiding that the liquid guiding head 101 with a fixed length is difficult to adapt to different abdominal drainage surgeries, thus greatly improving its applicable range.

[0031] Furthermore, the outer diameter of the above-mentioned threaded head 4 is smaller than the outer diameter of the liquid guiding head 101. By inserting the threaded head 4 into the main drainage tube 102 and performing a threaded connection with the main drainage tube 102, the main drainage tube 102 and the liquid guiding head 101 with the same outer diameter are inserted into the drainage opening, avoiding discomfort to the patient due to excessive dimensional differences.

[0032] Please refer to Figure 2 , in some embodiments of this embodiment, the above-mentioned liquid guiding head 101 includes a hemispherical puncture part 1011 and a tube-shaped liquid guiding part 1012, and a plurality of liquid guiding holes 5 are evenly spaced on the liquid guiding part 1012.

[0033] In this embodiment, the above-mentioned hemispherical head enters the abdominal tissue by blunt dissection, gradually pushing aside the muscles or fascia through the smooth curved surface, rather than the cutting intrusion of the traditional sharp puncture head. The blunt head can avoid piercing fragile tissues such as blood vessels and intestinal tubes, and is especially suitable for scenarios where adhesions may exist or the anatomical structure is complex after surgery, which can effectively reduce the risk of intraoperative accidental injury and reduce the complications of postoperative bleeding or organ perforation. In addition, the tubular structure provides a stable liquid flow path, and the liquid guide holes 5 are evenly distributed along the circumferential direction of the tube body, forming multi-directional drainage inlets. The evenly distributed liquid guide holes 5 avoid the concentration of local fluid accumulation and reduce the probability of a single pore being blocked by blood clots or tissue debris.

[0034] Please refer to Figure 5 , in some embodiments of this embodiment, the above-mentioned chuck 301 is evenly provided with exhaust holes 6 at intervals.

[0035] In this embodiment, the exhaust holes 6 evenly spaced on the above-mentioned chuck 301 form a micro-channel, allowing air to flow through the contact area between the chuck 301 and the abdominal wall tissue. When the chuck 301 and the annular airbag 201 cooperate to clamp the abdominal wall, the exhaust holes 6 can release the air in the locally compressed area, avoiding tissue ischemia caused by negative pressure adsorption or airbag extrusion. In addition, postoperative exudate or sweat on the skin surface can be discharged through the exhaust holes 6, avoiding the accumulation of liquid between the chuck 301 and the skin and reducing the risk of infection caused by a humid environment; the exhaust holes 6 promote gas exchange in the microenvironment around the wound, inhibit the reproduction of anaerobic bacteria, and assist postoperative healing.

[0036] Please refer to Figures 5 - 8 , in some embodiments of this embodiment, the above-mentioned limiting member 302 includes a sliding sleeve 3021, a locking ring 3022, a limiting elastic piece 3023 and a limiting block 3024. A clamping groove is formed on the sliding sleeve 3021. One end of the limiting elastic piece 3023 is fixed in the clamping groove. The limiting block 3024 is arranged at the end of the limiting elastic piece 3023 away from the clamping groove. The locking ring 3022 is sleeved on the sliding sleeve 3021, and the locking ring 3022 and the sliding sleeve 3021 are in threaded fit connection. The locking ring 3022 is used to push the limiting block 3024 located at the end of the limiting elastic piece 3023 to abut against the main drainage tube 102.

[0037] In this embodiment, the above-mentioned sliding sleeve 3021 is mounted on the outside of the drainage main pipe 102 and can slide axially along the main pipe. By changing the position of the sliding sleeve 3021, it can adapt to different abdominal wall thicknesses or surgical needs. The slot on the above-mentioned sliding sleeve 3021 provides a fixed fulcrum for the limiting spring 3023, limiting the spring to deform only in a specific direction, ensuring that the direction of the spring force applied is always toward the drainage main pipe 102. The above-mentioned locking ring 3022 is connected to the sliding sleeve 3021 by a threaded fit. When the locking ring 3022 is rotated, it moves axially along the thread, pushing the limit block 3024 to move toward the drainage main pipe 102. The pitch design of the thread can be fine-tuned, and the pressing force of the limit block 3024 on the drainage main pipe 102 can be accurately controlled by the rotation angle. One end of the above-mentioned limiting spring piece 3023 is fixed to the slot of the sliding sleeve 3021, and the other end is connected to the limiting block 3024. When the locking ring 3022 is pressed down, the limiting spring piece 3023 is elastically bent, driving the limiting block 3024 to abut against the drainage main pipe 102. The elasticity of the spring piece can provide a buffer when the drainage tube is pulled by external force to prevent sudden displacement; at the same time, the continuous rebound force maintains the clamping stability.

[0038] During use, slide the sleeve 3021 to the target position to preliminarily determine the clamping area; then rotate the locking ring 3022 to push the limit block 3024 through threaded transmission. The limit spring piece 3023 is compressed and deformed to generate radial clamping force, thereby fixing the drainage tube to the abdominal wall; the limit spring piece 3023 elastically provides continuous clamping force, while the locking ring 3022 thread prevents retreat, forming a dual fixation of elasticity and rigidity.

[0039] Please refer to Figure 8 In some implementations of this embodiment, the side of the above-mentioned limiting block 3024 away from the limiting spring piece 3023 is provided with an anti-slip groove 7, and the opening direction of the anti-slip groove 7 is perpendicular to the radial direction of the drainage main pipe 102.

[0040] In this embodiment, the direction of the anti-slip groove 7 is perpendicular to the radial direction of the drainage main pipe 102, that is, perpendicular to the axial direction of the main pipe, forming a transverse groove structure. When the limit block 3024 presses the drainage main pipe 102 through the locking ring 3022, the direction of the anti-slip groove 7 is perpendicular to the axial tension direction of the main pipe, forming an interlocking structure. When the drainage pipe is subjected to axial tension, the edge of the transverse groove forms a multi-point micro-interlock with the surface of the main pipe, significantly increasing the static friction and resisting the sliding of the drainage pipe. At the same time, the uniform distribution of the anti-slip groove 7 disperses the pressing force of the limit block 3024 to multiple independent contact points, avoiding deformation or damage of the drainage pipe caused by excessive local pressure.

[0041] Please refer to Figures 1 - 4 In some implementations of this embodiment, an annular receiving groove 8 for receiving the annular airbag 201 in an uninflated state is provided on the drainage main pipe 102 .

[0042] In this embodiment, an annular groove is formed on the above-mentioned main drainage tube 102, and the shape and size of the groove match those of the annular airbag 201 in the uninflated state; when the annular airbag 201 is uninflated, it can be tightly accommodated in the annular receiving groove 8 and will not protrude from the surface of the main drainage tube 102.

[0043] It should be noted that the annular airbag 201 is an inflatable elastic capsule, usually made of materials such as medical-grade silicone or rubber. In the uninflated state, the volume of the airbag is small, which is convenient for installation and replacement; after inflation, the volume of the airbag expands and can closely adhere to the inner wall of the abdominal cavity.

[0044] Please refer to Figure 1 , in some embodiments of this embodiment, a joint 9 is provided at one end of the above-mentioned main drainage tube 102 away from the liquid guide head 101, and the joint 9 includes a flushing pipeline 10 for backwashing the drainage pipeline.

[0045] In this embodiment, a joint 9 is provided at one end of the above-mentioned main drainage tube 102 away from the liquid guide head 101. The joint 9 is a component for connecting the main drainage tube 102 to other medical devices. A flushing pipeline 10 is provided inside or outside the joint 9, and this pipeline is specifically used for backwashing the drainage pipeline. One end of the flushing pipeline 10 is connected to the joint 9, and the other end can be connected to a flushing device to introduce flushing liquid. The backwashing function can effectively remove the blockages in the drainage pipeline and keep the pipeline unobstructed. This helps to ensure the smooth progress of the drainage process and avoid the risk of unsmooth drainage or complications caused by pipeline blockage.

[0046] Please refer to Figure 1 , in some embodiments of this embodiment, a flow-limiting clamp 11 is provided on the above-mentioned flushing pipeline 10.

[0047] In this embodiment, the above-mentioned flow-limiting clamp 11 is used to adjust the flow path of the flushing pipeline 10, which is convenient for first stopping the flow of the liquid in the flushing pipeline 10 by controlling the flow-limiting clamp 11 when not in use, and then covering the end with a cover, which is convenient for backwashing and the addition of drugs. It should also be noted that during backwashing, the joint 9 coaxial with the main drainage tube 102 is adjusted to a closed state to prevent the flushing liquid from flowing out through the main drainage tube 102. The above-mentioned flushing pipeline 10 is a branch pipeline on the joint 9, and the main pipeline of the joint 9 is used to guide abdominal cavity effusion, and a control valve (not marked in the figure) is provided on the main pipeline to facilitate controlling the opening and closing according to the flushing requirements.

[0048] When in use, take out the whole anti-leakage abdominal drainage tube, select a liquid guide head 101 with an appropriate length according to the depth of abdominal effusion, threadedly connect and fix the liquid guide head 101 to the drainage main pipe 102, align the liquid guide head 101 with the abdominal drainage stoma site. When the liquid guide part 1012 of the liquid guide head 101 reaches the drainage position and the liquid guide head 101 is inserted into the abdominal cavity until the annular airbag 201 completely reaches inside the abdominal cavity, stop pushing. Connect the inflation head 203 to an external inflation device, inflate the annular airbag 201, and then pull the annular airbag 201 to abut against the inner wall of the human abdominal tissue. Manually adjust the chuck 301 to abut against the outside of the human abdominal tissue, and fix the chuck 301 on the drainage main pipe 102 through the limiting member 302. Then connect a drainage bag to the joint 9 of the drainage main pipe 102.

[0049] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
