Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of abdominal cavity drainage, and particularly relates to a gas bag type fixed-free abdominal cavity drainage tube. BACKGROUND

[0002] Abdominal cavity drainage is a common means in clinical surgical treatment, which is used for discharging the effusion, blood, pus and the like in the abdominal cavity to promote postoperative recovery of patients and prevent complications such as infection. At present, the abdominal cavity drainage tube used in clinical treatment is mostly fixed in a traditional way, which is fixed on the body surface of the patient by a suture or is limited by friction between the drainage tube and the body surface, and such a way has many disadvantages.

[0003] During the drainage process, the drainage tube is prone to position deviation due to turning over of the patient, activity or external force pulling, and even partially comes out or excessively penetrates into the abdominal cavity, which affects the drainage effect and may seriously damage the organs in the abdominal cavity. Meanwhile, the traditional drainage tube lacks effective anti-blocking structure, and the omental tissue and intestinal canal in the abdominal cavity are prone to contact with the drainage hole, which causes the drainage hole to be blocked and the abdominal cavity effusion to be discharged, thereby causing problems such as infection and effusion accumulation and prolonging the treatment cycle of the patient.

[0004] In addition, bacteria are prone to grow at the contact position between the drainage tube and the body surface of the patient and the outer wall of the tube, and the axial movement of the tube during the activity of the patient may bring the bacteria and dirt on the body surface or the outer wall of the tube into the subcutaneous sinus, thereby increasing the risk of infection. The existing drainage tube lacks an active disinfection mechanism and needs to be manually disinfected by medical staff regularly, which is complicated and may cause disinfection to be not timely or not complete, thereby further increasing the probability of infection. Meanwhile, the fixing structure of the traditional drainage tube is inconvenient to adjust, cannot accurately adjust the position of the tube according to the actual drainage requirement of the patient, and is prone to cause additional stimulation to the patient during the adjustment process.

[0005] In addition, the existing drainage tube lacks effective buffer structure, and when the patient suddenly turns over, violently coughs or is subjected to external force pulling, the pulling force directly acts on the drainage tube in the body, which is prone to cause the drainage tube to be displaced or dropped or to cause pulling damage to the tissue in the abdominal cavity, thereby affecting the comfort and safety of the patient. In view of the above problems, there is an urgent need for an abdominal cavity drainage device which can solve the problems of unstable fixation of the drainage tube, easy blocking, easy infection, inconvenient position adjustment and lack of buffer protection. SUMMARY

[0006] The present application aims at solving the problems in the prior art that the drainage tube is prone to position deviation due to turning over of the patient, activity or external force pulling, bacteria are prone to grow at the contact position between the drainage tube and the body surface of the patient and the outer wall of the tube, and the drainage tube lacks effective buffer structure, and proposes a gas bag type fixed-free abdominal cavity drainage tube.

[0007] In order to achieve the above object, the present application adopts the following technical scheme: An air bag type fixed-free abdominal cavity drainage tube, comprising a main drainage tube, a silica gel corrugated pipe section I is integrally formed inside the main drainage tube, a silica gel corrugated pipe section II is integrally formed at one end of the main drainage tube; An auxiliary drainage tube is integrally formed at the end of the silica gel corrugated pipe section II away from the main drainage tube, and an annular air bag is fixedly connected to the outer wall of the auxiliary drainage tube; A plurality of carambola-shaped air bags are integrally formed on the outer wall of the annular air bag and communicate with the annular air bag; A limiting air bag is fixedly connected to the outer wall of the main drainage tube; A charging pipe is arranged inside the main drainage tube and fixed to the inner wall of the main drainage tube, and one end of the charging pipe communicates with the limiting air bag and the annular air bag; After the charging pipe is inflated, the limiting air bag is inflated to limit the main drainage tube, the carambola-shaped air bags are inflated to push away the abdominal cavity organs to form a fluid passage, and the omentum tissue is blocked to prevent the drainage hole from being blocked.

[0008] In a possible design, a fixing ring is further included, the fixing ring is sleeved outside the main drainage tube, a disinfecting assembly is arranged inside the fixing ring, an adhesive is arranged on one side of the fixing ring, and the adhesive can be attached to the surface of the patient to achieve auxiliary fixation.

[0009] In a possible design, the disinfecting assembly includes a medicine storage cavity formed in the inside of the fixing ring, an installation hole is formed on one side of the fixing ring, a dustproof ring is fixedly connected to the inner wall of the installation hole, an inverted conical liquid scraping lip is integrally formed on the other side of the fixing ring, the medicine storage cavity communicates with the installation hole, an annular sponge is arranged in the medicine storage cavity, the main drainage tube passes through the annular sponge when moving axially, the tube wall is coated with disinfectant to achieve "disinfection by moving", the inverted conical liquid scraping lip can scrape off dirt on the tube wall, and the dustproof ring blocks dust and bacteria.

[0010] In a possible design, an adjusting assembly is arranged on one side of the fixing ring, the adjusting assembly includes an annular groove formed on one side of the fixing ring, a rotating ring I is rotatably connected in the annular groove, a limiting circular plate is fixedly connected to one end of the rotating ring I, and a plurality of scale lines are arranged on the outer wall of the rotating ring I; An annular cavity is formed in the inside of the fixing ring, the annular cavity communicates with the annular groove, a rotating ring II is fixedly connected to one end of the rotating ring I, the rotating ring II is rotatably connected in the annular cavity, and an annular sliding groove is formed on one side of the rotating ring II, a plurality of limiting grooves that communicate with each other are formed in the inner wall of the annular sliding groove.

[0011] In a possible design, a braking assembly is arranged in the inside of the fixing ring, the braking assembly includes a rectangular cavity formed in the inside of the fixing ring, the rectangular cavity is located on one side of the annular cavity and communicates with the annular cavity, and a sliding rectangular plate is slidably connected in the rectangular cavity. A threaded hollow rod is rotatably inserted inside the fixed ring. The threaded hollow rod passes through the sliding rectangular plate and extends to the medicine storage cavity at its bottom. An operating block is fixedly connected to the top. A conical hole is opened inside the operating block and communicates with the threaded hollow rod. Multiple block-shaped rubbers are fixedly connected to the inner wall of the conical hole. Rotating the operating block can drive the sliding rectangular plate to move, so that the sliding rectangular plate can be engaged or disengaged from the limiting groove, thereby braking or unlocking the rotating ring II.

[0012] In one possible design, the silicone corrugated tube section I and silicone corrugated tube section II are made of medical-grade silicone. When subjected to external force, silicone corrugated tube section I and silicone corrugated tube section II can be stretched and deformed to absorb the instantaneous impact force and prevent the pulling force from acting directly on the drainage tube inside the body.

[0013] In one possible design, the annular sponge is made of a hydrophilic sponge material that can absorb and store disinfectant, ensuring the continuity of disinfection effect when the main drainage tube moves.

[0014] In one possible design, under normal conditions, multiple block-shaped rubbers press against each other to seal the conical hole. After inserting the needle into the conical hole, the disinfectant can be injected into the storage chamber through the threaded hollow rod to replenish the disinfectant.

[0015] In one possible design, the limiting circular plate is threadedly engaged with the external thread on the outer circumference of the main drainage tube. Rotating the limiting circular plate can drive the main drainage tube to move axially, and the adjustment position of the main drainage tube can be accurately controlled through the scale lines.

[0016] In this application, during use, the main drainage tube and auxiliary drainage tube are inserted into the patient's body as a whole. Inflation is achieved through an inflation tube, the end of which is connected to a pressure regulating valve and an inflation pump. The pressure regulating valve controls the inflation pressure between 0.02-0.05 MPa (adapting to the tolerance of abdominal tissue). After inflation, the limiting airbag and the annular airbag inflate synchronously, thus limiting the tubes. When the starfruit-shaped airbag inflates along with the annular airbag, the protruding starfruit-shaped airbag first contacts and pushes aside surrounding abdominal organs (such as intestines and greater omentum), creating a physically isolated fluid channel between the ribs. Abdominal fluid can flow into the deeper drainage hole through the groove, while large pieces of omentum tissue, due to their large size, are blocked by the ribs of the airbag and cannot contact or block the drainage hole. This structure utilizes the physical shape of the airbag to achieve a "liquid-solid separation" filtration effect. Furthermore, the fixing ring can be adhered to the user's skin using adhesive on the side, allowing for active disinfection. When the patient moves or the tube is withdrawn, the main drainage tube moves axially and passes through the iodine-soaked sponge in the drug storage chamber, forcibly coating the tube wall with disinfectant, achieving "disinfection upon movement." It also prevents contamination. If the main drainage tube attempts to slide into the abdominal cavity, the lower inverted conical scraping lip will "scrape away" bacteria, fluid, and contaminants on the tube wall, preventing them from being carried into the subcutaneous sinus tract. It also provides dust protection; the upper dustproof ring blocks large particles of dust and bacteria in the air from contacting the tube wall, reducing the source of contamination. The annular sponge is made of hydrophilic sponge material with good disinfectant absorption capacity, ensuring continuous disinfection effect. The annular sponge is detachable and can be replaced through the inspection port on the side of the drug storage chamber. It is recommended to replace it every 3-5 days. There is a drainage hole at the bottom of the drug storage chamber. Regularly open the drainage hole to clean the internal sediment and ensure disinfection effect. By rotating the operating block, the operating block drives the threaded hollow rod to rotate, which in turn drives the sliding rectangular plate to move downward. The sliding rectangular plate moves from the inside of the limiting groove to the inside of the annular groove, which releases the braking state of the rotating ring II. At this time, the limiting circular plate can be rotated, which drives the rotating ring I to rotate, and the rotating ring I drives the rotating ring II to rotate. The limiting circular plate engages with the external thread, thereby adjusting the position of the main drainage pipe. The current position can be quickly determined through the scale lines. Under normal circumstances, multiple blocks of rubber press against each other to seal the conical hole. After inserting the needle into the conical hole, the disinfectant can be injected directly into the storage chamber through the hollow of the threaded hollow rod to achieve the liquid addition process. Furthermore, due to the presence of silicone corrugated tube section II and silicone corrugated tube section I, the pulling force can be buffered. When the patient turns over, pulls on the tube, or coughs violently, the external pulling force will first cause the corrugated tube section to stretch and deform (rather than directly pulling the internal drainage tube), or the tube body will slide a short distance of "empty stroke" within the limiting sliding cavity to "digest" the instantaneous impact force.

[0017] Beneficial effects: Inflation of the limiting balloon and the ring balloon through the inflation tube effectively limits the main drainage tube after the limiting balloon inflates. After the starfruit-shaped balloon inflates, it comes into contact with the abdominal tissue, forming multi-point support. Together with the fixation ring, it is adhered to the patient's body surface with adhesive, achieving double limiting. This effectively prevents the drainage tube from shifting, dislodging, or going too deep due to patient movement, turning over, or external traction, ensuring the stability of the drainage process.

[0018] When inflated, the starfruit-shaped airbag forms a raised structure that can contact and push aside the surrounding abdominal organs, creating a physically isolated fluid channel between the ribs. Ascites can flow into the deep drainage hole through the grooves between the airbags, while large pieces of omentum tissue are blocked by the airbag ribs due to their large size and cannot contact the drainage hole, achieving a liquid-solid separation filtration effect, significantly reducing the probability of drainage hole blockage, ensuring smooth drainage of ascites, and reducing complications caused by fluid accumulation.

[0019] The fixing ring has a drug storage chamber and an annular sponge inside. The drug storage chamber can store disinfectant. When the main drainage tube moves axially, the tube wall will pass through the annular sponge in the drug storage chamber, forcibly applying disinfectant, achieving disinfection as soon as it moves. The inverted conical scraping lip on one side of the fixing ring can scrape off bacteria, fluid, and dirt on the tube wall when the main drainage tube attempts to slide into the abdominal cavity, preventing them from being carried into the subcutaneous sinus tract. The dustproof ring on the inner wall of the installation hole can block large particles of dust and bacteria in the air from contacting the tube wall, reducing contamination at the source, improving the disinfection and protection effect from multiple dimensions, and reducing the probability of infection.

[0020] Rotating the operating block can drive the threaded hollow rod to rotate, which in turn drives the sliding rectangular plate to move down, allowing the sliding rectangular plate to move from the limiting groove into the annular slide groove, releasing the brake on the rotating ring II. At this time, rotating the limiting circular plate can drive the rotating ring I and rotating ring II to rotate. Combined with the cooperation of the limiting circular plate and the external thread, the position of the main drainage tube can be adjusted. The scale lines can help medical staff quickly grasp the current position of the tube, achieve precise adjustment, adapt to the needs of different patients and different drainage stages, and are convenient to operate and highly accurate.

[0021] The conical hole inside the operating block is connected to the threaded hollow rod. Under normal circumstances, multiple rubber blocks squeeze each other to seal the conical hole, preventing disinfectant leakage or contaminant entry. When disinfectant needs to be replenished, insert the syringe into the conical hole, and the disinfectant can be directly injected into the storage chamber through the hollow structure of the threaded hollow rod without disassembling the fixing ring. This makes the operation convenient and ensures the continuity of disinfection work.

[0022] The integrally formed silicone corrugated tube section I inside the main drainage tube and the silicone corrugated tube section II at one end can act as a buffer. When the patient turns over, pulls on the tube, or coughs violently, the external pulling force will first stretch and deform the corrugated tube section, or the tube body will slide a short distance in the limiting sliding cavity to absorb the instantaneous impact force, avoid the pulling force acting directly on the drainage tube inside the body, reduce the risk of drainage tube displacement and dislodgement, and at the same time reduce the traction damage to the abdominal tissues, improve the patient's comfort and treatment safety.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] In one embodiment: Refer to Figures 1-7This pneumatic, non-fixed abdominal drainage tube includes a main drainage tube 1, a silicone corrugated tube segment I 2, an inflation tube 3, a limiting airbag 5, a starfruit-shaped airbag 6, an auxiliary drainage tube 7, an annular airbag 8, a silicone corrugated tube segment II 9, a fixing ring 10, and matching sterilization, adjustment, and braking components. The components are assembled as follows to achieve overall functionality: The main drainage tube 1 has a silicone corrugated tube segment I 2 integrally formed inside; one end of the main drainage tube 1 has a silicone corrugated tube segment II 9 integrally formed; the other end of the silicone corrugated tube segment II 9 has an auxiliary drainage tube 7 integrally formed. To buffer external force, the silicone corrugated tube segments I 2 and II 9 are made of medical-grade silicone, which can stretch and deform under tension to absorb instantaneous impact. An annular airbag 8 is fixedly installed on the outer wall of the auxiliary drainage tube 7. Multiple interconnected starfruit-shaped airbags 6 are integrally formed on the outer wall of the annular airbag 8. A limiting airbag 5 is fixedly installed on the outer wall of the main drainage tube 1, and an inflation tube 3 is fixedly inserted through the inside of the main drainage tube 1. Specifically, one end of the inflation tube 3 is connected to the limiting airbag 5 and the annular airbag 8. Based on this, air is inflated into the limiting airbag 5 and the annular airbag 8 through the inflation tube 3. After the limiting airbag 5 is inflated, it can limit the main drainage tube 1. When the starfruit-shaped airbag 6 is inflated with the annular airbag 8, the protruding starfruit-shaped airbag 6 first contacts and pushes away the surrounding abdominal organs, creating a physically isolated fluid channel between the ribs. The ascites can flow into the deep drainage hole through the groove, while large pieces of omentum tissue, due to their large volume, are blocked by the ribs of the airbag and cannot contact and block the drainage hole, achieving a "liquid-solid separation" filtration effect.

[0027] The fixing ring 10 is located outside the main drainage tube 1. In order to achieve auxiliary fixation and disinfection protection of the main drainage tube 1, a disinfection component is provided inside the fixing ring 10. Further, the disinfection component includes a drug storage chamber 15 opened inside the fixing ring 10. A mounting hole 28 is opened on one side of the fixing ring 10, and a dustproof ring 17 is fixedly installed on the inner wall of the mounting hole 28. An inverted conical scraping lip 27 is integrally formed on the other side of the fixing ring 10. The drug storage chamber 15 is connected to the mounting hole 28, and an annular sponge 18 is provided inside the drug storage chamber 15. Specifically, a self-adhesive strip 19 is provided on one side of the fixing ring 10, which can be adhered to the user's body surface. Based on this, when the patient moves or the tube is withdrawn, the main drainage tube 1 moves axially and passes through the annular sponge 18 in the drug storage chamber 15. The tube wall is forcibly coated with disinfectant absorbed by the annular sponge 18, achieving "disinfection upon movement". If the main drainage tube 1 attempts to slide into the abdominal cavity, the lower inverted conical scraping lip 27 will "scrape off" bacteria, fluid, and dirt on the tube wall, preventing them from being carried into the subcutaneous sinus tract. The upper dustproof ring 17 blocks large particles of dust and bacteria in the air from contacting the tube wall, reducing the source of contamination. Preferably, the annular sponge 18 is made of hydrophilic sponge material, which has good disinfectant absorption capacity, ensuring the continuity of disinfection effect.

[0028] One side of the fixed ring 10 is provided with an adjustment component for adjusting the position of the main drainage tube 1. Furthermore, the adjustment component includes an annular groove 16 opened on one side of the fixed ring 10. A rotating ring I 12 is rotatably connected inside the annular groove 16. A limiting circular plate 14 is fixedly installed at one end of the rotating ring I 12. An annular cavity 29 is opened inside the fixed ring 10. The annular cavity 29 is connected to the annular groove 16. A rotating ring II 21 is fixedly installed at one end of the rotating ring I 12. The rotating ring II 21 is rotatably connected inside the annular cavity 29. An annular groove 22 is opened on one side of the rotating ring II 21. Multiple interconnected limiting grooves 23 are opened on the inner wall of the annular groove 22. The fixed ring 10 is equipped with a braking assembly for braking the adjustment component. Specifically, the braking assembly includes a rectangular cavity 30 inside the fixed ring 10, which is located on one side of the annular cavity 29 and communicates with it. A sliding rectangular plate 20 is slidably connected inside the rectangular cavity 30. A threaded hollow rod 26 rotatably passes through the fixed ring 10, threaded through the sliding rectangular plate 20. Two guide holes are symmetrically arranged on the sliding rectangular plate 20 corresponding to both sides of the threaded hollow rod 26. Guide rods pass through the guide holes, and the two ends of the guide rods are respectively connected to the upper and lower parts of the rectangular cavity 30. The wall is fixedly connected; the bottom of the threaded hollow rod 26 extends into the medicine storage chamber 15, and the top is fixedly installed with an operating block 13. The operating block 13 has a conical hole 25 inside, which communicates with the threaded hollow rod 26. Multiple block rubbers 24 are fixedly installed on the inner wall of the conical hole 25, and an annular elastic sealing ring is fitted on the outside of the block rubbers 24 to form a double sealing structure, which further improves the sealing reliability of the conical hole 25 and prevents disinfectant leakage or external pollutants from entering. One end of the sliding rectangular plate 20 extends into the annular groove 22, and the sliding rectangular plate 20 is used in conjunction with the limiting groove 23. Based on this, rotating the operating block 13 can drive the threaded hollow rod 26 to rotate, and the threaded hollow rod 26 can drive the sliding rectangular plate 20 to move down. The sliding rectangular plate 20 moves from the inside of the limiting groove 23 to the inside of the annular slide groove 22, releasing the braking state of the rotating ring II 21. At this time, rotating the limiting circular plate 14 can drive the rotating ring I 12 to rotate, and the rotating ring I 12 can drive the rotating ring II 21 to rotate. The limiting circular plate 14 cooperates with the external thread 4 to adjust the position of the main drainage tube 1. The current position can be quickly understood through the scale line 11. Under normal circumstances, multiple block rubbers 24 squeeze each other to seal the conical hole 25. After inserting the needle into the conical hole 25, the disinfectant can be directly injected into the drug storage chamber 15 through the hollow structure of the threaded hollow rod 26 to realize the liquid addition process.

[0029] Based on this, the usage process of the drainage tube is as follows: The main drainage tube 1 and the auxiliary drainage tube 7 are inserted into the patient's body as a whole. Inflation is carried into the device through the inflation tube 3, causing the limiting airbag 5, the starfruit-shaped airbag 6, and the ring airbag 8 to inflate and complete the initial limiting and anti-blocking structure deployment of the tube; the fixing ring 10 is attached to the patient's body surface with adhesive tape 19 to complete the surface fixation of the device; when it is necessary to adjust the position of the main drainage tube 1, after rotating the operating block 13 to release the brake, the limiting circular plate 14 is rotated and adjusted to the appropriate position with reference to the scale line 11. The operating block 13 is rotated in the opposite direction to make the sliding rectangular plate 20 fit into the corresponding limiting groove 23 to achieve the adjusted braking fixation; when the disinfectant in the drug storage chamber 15 is insufficient, the needle is inserted into the conical hole 25 to replenish the disinfectant in the drug storage chamber 15. During use, when the patient turns over, pulls on the tube, or coughs violently, the silicone corrugated tube section I2 and silicone corrugated tube section II9 will first undergo tensile deformation to absorb the instantaneous impact force, preventing the pulling force from directly dragging the internal drainage tube and ensuring the safety of use.

[0030] This application can be used in the field of abdominal drainage, or in other fields applicable to this application.

[0031] In another embodiment: Reference Figures 1-7 A balloon-type non-fixed abdominal drainage tube is used in the field of abdominal drainage. The structure of this embodiment is basically the same as that of the previous embodiment, except that: the outer wall of the rotating ring I12 is provided with multiple scale lines 11.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
