Description

Technical Field

[0001] This invention relates to the field of drainage tube technology, specifically to a permeable drainage tube for clinical use in tumor treatment. Background Technology

[0002] In oncology, most patients require drainage tubes after surgery. However, due to various reasons, drainage fluid often fails to enter the tube and instead leaks out from the gap between the abdominal incision and the outer wall of the tube. This is particularly noticeable in patients with significant postoperative pleural or peritoneal effusion. Furthermore, the length of the drainage tube within the patient's body cannot be adjusted according to the actual situation during insertion. Because the tube's position is fixed, it may come into contact with surrounding tissues during patient movements, causing pain or discomfort and potentially leading to postoperative inflammation. Additionally, current drainage tubes are typically straight-through, which can easily become blocked, hindering drainage and significantly impacting the patient's postoperative recovery.

[0003] Publication number CN115957389A discloses a non-permeable drainage tube for clinical use in oncology. It is fixed by a suction cup, effectively securing the drainage tube. Simultaneously, a sponge pad absorbs small amounts of tumor exudate, preventing it from flowing along the skin surface and causing wound infection. The suction tube and drainage tube allow for separate collection of tumor exudate and drainage fluid. Collecting the tumor exudate facilitates the determination of the cause and etiology of tumor formation by examining its properties, preventing missed diagnoses due to low early-stage cancer cell counts and effectively improving the accuracy of test results. However, this patent still has the following problems in practical use: Although the anti-permeability drainage tube used in clinical oncology is secured with a suction cup, patients may move during treatment. Accidental contact with the tube can cause it to dislodge, and the suction force of the suction cup is affected by the patient's skin, leading to further dislodgement. Dislodgement of the drainage tube and suction cup can cause wound tearing or secondary infection, hindering rapid wound healing. CN115645711A discloses a fixation device to prevent drainage tube slippage. While this device improves installation stability by using an installation mechanism and fixing components, the tube can still dislodge under significant external force. For example, a patient may press on the drainage tube while asleep or unconsciously turning over, causing it and the fixing components to tear the wound, resulting in secondary damage and further hindering wound healing.

[0004] Therefore, a non-permeable drainage tube for clinical use in tumor treatment was proposed to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a non-permeable drainage tube for clinical use in tumor treatment, in order to solve the problem that the drainage tube mentioned in the background art still falls off when subjected to a large external force, such as when the patient is asleep or unconsciously turns over and presses on the drainage tube, causing the drainage tube and fixation components to tear the wound, causing secondary damage to the wound and thus affecting the rapid healing of the wound.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: This anti-permeability drainage tube for clinical use in tumors utilizes the meshing gears on both sides of the clamping stent to engage with the meshing rack inside the rack and pinion protective box while the clamping stent is moving relative to it. This meshing gears drive the clamping bidirectional threaded rod to rotate, causing the clamping threaded sleeves on both sides to move relative to the limiting sliding box, thereby achieving longitudinal clamping of the wound and improving the wound clamping effect. It is suitable for round or short wounds. When the wound is long and narrow, to avoid the wound from opening due to longitudinal compression, the electric telescopic mechanism inside the limiting sliding box can be used. The lever drives the second clamping bracket at the bottom of the limiting sliding box to rise, causing the clamping arc plate to separate from the skin on both sides of the wound. The clamping arc plate at the bottom of the clamping bracket clamps the strip-shaped wound, improving the clamping effect. When the pulling force is large, the fixing wedge will move relative to the wound, thus allowing the fixing sleeve to disengage. When the pulling force is small, it can clamp and fix the drainage tube, preventing it from falling off. When the pulling force is large, it can automatically pull out the drainage tube, preventing it from pulling on the wound and causing tearing. This facilitates wound protection. The specific details are as follows: 1. By setting up a wound clamping mechanism, not only can the first clamping bracket and the rack and pinion protective box be fixed near the wound using medical fixation tape, but the elastic force of the connecting spring and the clamping spring also causes the clamping sliding sleeve to move the clamping bracket closer together. The clamping arc-shaped plate at the bottom of the clamping bracket can then conform to the skin around the patient's wound. The elastic force of the adjusting spring causes the adjusting sliding sleeve to slide outside the adjusting sliding rod, simultaneously rotating the adjusting rotating rod. Under the action of the first rotating support, the adjusting rotating plate drives the clamping arc-shaped plate to rotate, thus ensuring the clamping arc... The clamping plate fits tightly against the skin. Under the relative movement of the clamping support, the curved plate clamps the wound, preventing tearing or infection in case the drainage tube is accidentally pulled out, which would hinder rapid wound healing. Simultaneously, the clamping support utilizes the meshing gears on both sides to engage with the internal rack of the rack and pinion protective box. This meshing gears drive the bidirectional threaded clamping rod to rotate, causing the threaded clamping sleeves on both sides to move relative to the limiting sliding box, thus achieving longitudinal clamping of the wound and improving the clamping effect. It is suitable for circular wounds. For shorter wounds, especially those that are elongated, to prevent the wound from reopening due to longitudinal compression, the electric telescopic rod inside the limiting sliding box can be used to raise the second clamping bracket at the bottom of the limiting sliding box. This separates the clamping arc plate from the skin on both sides of the wound, and the clamping arc plate at the bottom of the bracket clamps the elongated wound, improving the clamping effect. Utilizing the sliding connection between the fixed sliding rod and the fixed sliding sleeve inside the fixed bracket, and under the elastic force of the fixed spring, the fixed limiting plate and the fixed inclined block move relative to each other. The fixed inclined block and the fixed slots on both sides of the fixed sleeve can be engaged to fix the sleeve, which is convenient for fixing the third drainage tube and the drainage tube connector. When the drainage tube is subjected to a large external force, the inclined groove at the bottom of the fixed slot and the inclined groove at the bottom of the fixed inclined block can be used to make the fixed inclined block move relative to each other. This allows the fixed sleeve, the drainage tube connector and the third drainage tube to be pulled out from the inside of the first clamping bracket, which is convenient for protecting the wound and avoids the drainage tube being subjected to a large pulling force, which could cause the wound to tear and is not conducive to wound protection. 2. By setting up a drainage tube fixing mechanism, not only can the first drainage tube, second drainage tube, drainage bottle, and third drainage tube be used to perform surgical drainage operations, draining abnormal body fluids such as pus, blood, and exudate, reducing the environment for bacterial growth and lowering the risk of postoperative infection, but also, when the drainage bottle is half full, the liquid can be drained by opening the drain plug. The impermeable sponge at the bottom of the fixing sleeve can absorb the overflowing liquid, preventing leakage. When the drainage tube is pulled by external force, it will cause the drainage tube connector to slide inside the fixing sleeve, causing the drainage tube to drive the clamping sliding frame to rise. Under the action of the clamping rotating rod, the clamping sliding sleeve slides relative to the outside of the clamping sliding rod, while simultaneously causing the clamping limiting plate and the clamping connecting frame to move closer to each other. The clamping anti-sliding block is used to fix the first drainage tube. The outer side is clamped to prevent the first drainage tube from detaching, improving the connection stability of the first drainage tube. The first drainage tube is made of a relatively hard material to prevent deformation due to squeezing of the clamping anti-slip block. The second and third drainage tubes are made of medical soft tubing, which facilitates drainage operations. The elastic force of the clamping spring is less than that of the fixing spring. Therefore, when the drainage tube is subjected to a small external force, the clamping anti-slip block first clamps and fixes the first drainage tube. When the pulling force is large, the fixing wedge will move relative to it, thereby achieving the phenomenon of the fixing sleeve detaching. When the pulling force is small, it can clamp and fix the drainage tube to prevent it from falling off. When the pulling force is large, it can achieve automatic pull-out of the drainage tube, preventing the drainage tube from pulling on the wound and causing the wound to tear, thus facilitating wound protection.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-7The present invention provides a technical solution: a tumor clinical anti-permeability drainage tube, including a wound clamping mechanism 1 and a fixing bracket 124 installed on the top of the wound clamping mechanism 1. A drainage tube fixing mechanism 2 is provided inside the wound clamping mechanism 1, and a drainage bottle 207 is provided at the end of the drainage tube fixing mechanism 2. The wound clamping mechanism 1 includes a first clamping bracket 101, with rack protective boxes 102 fixedly installed on both sides of the bottom of the first clamping bracket 101. Medical fixing tape 103 is fixedly installed at the bottom of the rack protective box 102. A meshing rack 104 is fixedly installed inside the rack protective box 102. A through groove 105 is opened at the center of the inside of the first clamping bracket 101. The inside of the first clamping bracket 101 is fixed around the perimeter. A pressing sliding rod 106 is fixedly installed. A pressing sliding sleeve 107 is slidably connected to the outer side of the pressing sliding rod 106. A pressing spring 108 is fixedly installed on one side of the pressing sliding sleeve 107. A pressing rotating rod 109 is rotatably connected to the top of the pressing sliding sleeve 107. A clamping bracket 110 is fixedly installed at the bottom of the two pressing sliding sleeves 107. Both ends of the two clamping brackets 110 are rotatably connected to meshing gears 111. A clamping bidirectional threaded rod 112 is fixedly installed between the two meshing gears 111. A clamping threaded sleeve 113 is symmetrically threaded to the outer side of the two clamping bidirectional threaded rods 112. A limit sliding box 114 is fixedly installed on the outer side of the clamping threaded sleeve 113. An electric telescopic rod 1 is fixedly installed on the inner bottom of the limit sliding box 114. 15. A second clamping bracket 116 is fixedly installed at the bottom of both the electric telescopic rod 115 and the clamping bracket 110. An adjusting sliding rod 117 is fixedly installed inside the second clamping bracket 116. An adjusting sliding sleeve 118 is slidably connected to the outer side of the adjusting sliding rod 117. An adjusting spring 119 is fixedly installed on one side of the adjusting sliding sleeve 118. An adjusting rotating rod 120 is rotatably connected to the bottom of the adjusting sliding sleeve 118. An adjusting rotating plate 121 is rotatably connected to the bottom of the adjusting rotating rod 120. A first rotating support 122 is rotatably connected to the top side of the adjusting rotating plate 121. The first rotating support 122 is fixedly installed on the bottom side of the second clamping bracket 116. A clamping arc plate 123 is fixedly installed at the bottom of the adjusting rotating plate 121. The first clamping bracket 101 and the rack and pinion protective box 102 are fixed to the vicinity of the wound using medical fixation tape 103. The elastic force of the connecting spring 132 and the clamping spring 108 causes the clamping sliding sleeve 107 to move the clamping bracket 110 closer together. The clamping arc-shaped plate 123 at the bottom of the clamping bracket 110 can then conform to the skin around the patient's wound. The elastic force of the adjusting spring 119 causes the adjusting sliding sleeve 118 to slide outside the adjusting sliding rod 117, simultaneously rotating the adjusting rotating rod 120. Under the action of the first rotating support 122, the adjusting rotating plate 121 drives the clamping arc-shaped plate 123 to rotate, ensuring a tight fit between the clamping arc-shaped plate 123 and the skin. The relative movement of the clamping bracket 110 further enhances this effect.The wound is clamped using the compression arc plate 123 to prevent tearing or infection of the wound should the drainage tube be accidentally pulled out, which would hinder rapid wound healing.

[0020] Please see Figures 5-9The fixed bracket 124 is rotatably connected to the pressing rotating rod 109. A pull-out groove 125 is provided at the center of the fixed bracket 124. Fixed sliding rods 126 are fixedly installed on both sides of the bottom of the fixed bracket 124. Fixed sliding sleeves 127 are slidably connected to the outer sides of both fixed sliding rods 126. A fixed spring 128 is fixedly installed on one side of the fixed sliding sleeve 127. A fixed limiting plate 129 is fixedly installed at the bottom of the fixed sliding sleeve 127. A fixed inclined block 130 is fixedly installed on one side of the fixed limiting plate 129. Connecting telescopic rods 131 are symmetrically installed on both sides of the bottom of the fixed bracket 124. Connecting springs 132 are slidably connected to the outer sides of the connecting telescopic rods 131. The connecting springs 132 are respectively connected to the first pressing bracket 109. 1. The first clamping bracket 101 is fixedly connected to the fixed bracket 124. Both sides of the first clamping bracket 101 are rotatably connected to the strap rotating support 133. The outer sides of the two strap rotating supports 133 are wrapped with connecting straps 134. Both ends of the connecting straps 134 are fixedly installed with fixing buckles 135. Several engaging buckles 136 are fixedly installed on the side of the connecting straps 134 near the connecting straps 134. The fixing buckles 135 and engaging buckles 136 are engaged and connected. When the clamping bracket 110 moves relative to the clamping bracket 110, the meshing gears 111 on both sides of the clamping bracket 110 are engaged with the meshing rack 104 inside the rack protective box 102. The meshing gears 111 drive the clamping bidirectional threaded rod 112 to rotate, so that the clamping threaded sleeves 113 on both sides are driven to limit the movement. The sliding box 114 moves relative to the wound, thereby achieving longitudinal clamping and improving the clamping effect. It is suitable for round or short wounds. When the wound is long and narrow, in order to avoid the wound from opening due to longitudinal compression, the electric telescopic rod 115 inside the limiting sliding box 114 can drive the second clamping bracket 116 at the bottom of the limiting sliding box 114 to rise, so that the clamping arc plate 123 is separated from the skin on both sides of the wound. The clamping arc plate 123 at the bottom of the clamping bracket 110 clamps the long and narrow wound, improving the clamping effect. Utilizing the sliding connection between the fixed sliding rod 126 and the fixed sliding sleeve 127 inside the fixed bracket 124, and under the elastic force of the fixed spring 128, the fixed limiting plate is fixed. The relative movement of 129 and the fixing wedge 130, utilizing the engagement connection between the fixing wedge 130 and the fixing slots 202 on both sides of the fixing sleeve 201, enables the fixing sleeve 201 to be fixed, facilitating the fixation of the third drainage tube 209 and the drainage tube connector 203. When the drainage tube is subjected to a large external force, the relative movement of the fixing wedge 130 is achieved by utilizing the relative sliding characteristic of the inclined groove at the bottom of the fixing slot 202 and the inclined groove at the bottom of the fixing wedge 130. This allows the fixing sleeve 201, the drainage tube connector 203, and the third drainage tube 209 to be pulled out from inside the first clamping bracket 101, facilitating wound protection and preventing the drainage tube from being subjected to excessive pulling force, which could cause wound tearing and hinder wound protection.The connecting strap 134 is made of biocompatible materials such as elastic straps and Velcro, combining support and comfort in its design to improve patient comfort.

[0021] Please see Figure 1 , Figures 9-10 The drainage tube fixing mechanism 2 includes a fixing sleeve 201, with fixing slots 202 on both sides of the fixing sleeve 201. A drainage tube connector 203 is slidably connected to the center of the fixing sleeve 201. An anti-permeability sponge 204 is fixedly installed at the bottom of the fixing sleeve 201. A third drainage tube 209 is fixedly connected to the bottom of the drainage tube connector 203. A first drainage tube 205 is fixedly connected to the top of the drainage tube connector 203. A second drainage tube 206 is fixedly installed at the end of the first drainage tube 205 away from the drainage tube connector 203. The end of the second drainage tube 206 is fixed... The device is equipped with a drainage bottle 207, and a drain plug 208 is threadedly connected to the top side of the drainage bottle 207. The drainage operation is achieved by using the first drainage tube 205, the second drainage tube 206, the drainage bottle 207 and the third drainage tube 209 to drain abnormal body fluids such as pus, blood and exudate, reduce the environment for bacterial growth and reduce the risk of postoperative infection. When the liquid inside the drainage bottle 207 is half full, the liquid can be drained by opening the drain plug 208. The anti-permeability sponge 204 at the bottom of the fixing sleeve 201 can absorb the overflowing liquid to prevent the liquid from seeping in.

[0022] Please see Figures 9-11A connecting cover 210 is fixedly installed on the top of the fixed sleeve 201. A clamping rotating rod 211 is rotatably connected around the fixed sleeve 201 near the drainage tube connector 203. A clamping sliding sleeve 212 is rotatably connected to the top of the clamping rotating rod 211. A clamping sliding rod 213 is slidably connected inside the clamping sliding sleeve 212. A clamping spring 214 is fixedly installed on one side of the clamping sliding sleeve 212. A clamping limiting plate 215 is fixedly installed on the top of the clamping sliding sleeve 212. A clamping spring is fixedly installed on one side of the clamping limiting plate 215. A clamping connecting frame 216 is clamped, and a clamping anti-slip block 217 is fixedly installed at the end of the clamping connecting frame 216. A clamping sliding frame 218 is fixedly installed on the outside of the clamping sliding rod 213. The clamping sliding frame 218 is fixedly installed on the top of the drainage tube connector 203. When the drainage tube is pulled by an external force, it will drive the drainage tube connector 203 to slide inside the fixed sleeve 201, causing the drainage tube to drive the clamping sliding frame 218 to rise. Under the action of the clamping rotating rod 211, the clamping sliding sleeve 212 is positioned on the outside of the clamping sliding rod 213. While sliding, the clamping limiting plate 215 and the clamping connecting frame 216 move closer together. The clamping anti-slip block 217 clamps the outer side of the first drainage tube 205, preventing it from detaching and improving its connection stability. The first drainage tube 205 is made of a relatively hard material to prevent deformation from the clamping anti-slip block 217. The second drainage tube 206 and the third drainage tube 209 are made of medical-grade tubing for easy drainage. The spring force of the clamping spring 214 is less than... The spring force of the fixed spring 128 is such that when the drainage tube is subjected to a small external force, the clamping anti-slip block 217 first clamps and fixes the first drainage tube 205. When the pulling force is large, the fixing inclined block 130 will move relative to it, thereby realizing the phenomenon of the fixing sleeve 201 disengaging. When the pulling force is small, the drainage tube can be clamped and fixed to prevent the drainage tube from falling off. When the pulling force is large, the drainage tube can be automatically pulled out to prevent the drainage tube from pulling the wound and causing the wound to tear, thus facilitating the protection of the wound.

[0023] Working principle: Before using this type of anti-permeability drainage tube for clinical use in tumor treatment, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 11As shown, firstly, the first clamping bracket 101 and the rack and pinion protective box 102 are fixed near the wound using medical fixation tape 103. The elastic force of the connecting spring 132 and the clamping spring 108 causes the clamping sliding sleeve 107 to move the clamping bracket 110 closer together. The clamping arc plate 123 at the bottom of the clamping bracket 110 can fit against the skin around the patient's wound. The elastic force of the adjusting spring 119 causes the adjusting sliding sleeve 118 to slide outside the adjusting sliding rod 117, simultaneously rotating the adjusting rotating rod 120. Under the action of the first rotating support 122, the adjusting rotating plate 121 drives the clamping arc plate 123 to rotate, ensuring a tight fit between the clamping arc plate 123 and the skin. With the relative movement of the clamping bracket 110, the clamping arc plate 123 clamps the wound, preventing wound tearing or infection in case the drainage tube is accidentally pulled out, which would hinder rapid wound healing.

[0024] Secondly, while the clamping bracket 110 moves relative to the wound, the meshing gears 111 on both sides of the clamping bracket 110 engage with the meshing rack 104 inside the rack and pinion protective box 102. This causes the meshing gears 111 to drive the clamping bidirectional threaded rod 112 to rotate, which in turn causes the clamping threaded sleeves 113 on both sides to drive the limiting sliding box 114 to move relative to each other. This achieves longitudinal clamping of the wound and improves the clamping effect. It is suitable for round or short wounds. When the wound is long and narrow, to avoid the wound from opening due to longitudinal compression, the electric telescopic rod 115 inside the limiting sliding box 114 can drive the second pressing bracket 116 at the bottom of the limiting sliding box 114 to rise. This separates the pressing arc plate 123 from the skin on both sides of the wound, and the pressing arc plate 123 at the bottom of the clamping bracket 110 clamps the long wound, improving the clamping effect. The fixed bracket 124 is used to further enhance the clamping effect. The fixed sliding rod 126 and the fixed sliding sleeve 127 are slidably connected. Under the elastic force of the fixed spring 128, the fixed limiting plate 129 and the fixed inclined block 130 can move relative to each other. The fixed inclined block 130 is engaged with the fixed slots 202 on both sides of the fixed sleeve 201 to fix the sleeve 201, which facilitates the fixation of the third drainage tube 209 and the drainage tube connector 203. When the drainage tube is subjected to a large external force, the inclined groove at the bottom of the fixed slot 202 slides relative to the inclined groove at the bottom of the fixed inclined block 130, which allows the fixed inclined block 130 to move relative to each other. This allows the fixed sleeve 201, the drainage tube connector 203 and the third drainage tube 209 to be pulled out from inside the first clamping bracket 101, which is convenient for wound protection and avoids the drainage tube being subjected to a large pulling force, which could cause the wound to tear and is not conducive to wound protection.

[0025] Finally, the first drainage tube 205, the second drainage tube 206, the drainage bottle 207, and the third drainage tube 209 are used to perform the surgical drainage operation, draining abnormal body fluids such as pus, blood, and exudate, reducing the environment for bacterial growth, and lowering the risk of postoperative infection. When the drainage bottle 207 is half full, the liquid can be drained by opening the drain plug 208. The anti-permeability sponge 204 at the bottom of the fixing sleeve 201 can absorb the overflowing liquid to prevent leakage. When the drainage tube is pulled by an external force, it will cause the drainage tube connector 203 to slide inside the fixing sleeve 201, causing the drainage tube to drive the clamping sliding frame 218 to rise. Under the action of the clamping rotating rod 211, the clamping sliding sleeve 212 slides relative to the outside of the clamping sliding rod 213, while driving the clamping limiting plate 215 and the clamping connecting frame 216 to move closer to each other. The clamping anti-sliding block 217 is used to clamp the first drainage tube 205. The outer side of 05 is clamped to prevent the first drainage tube 205 from detaching, thus improving the connection stability of the first drainage tube 205. The material of the first drainage tube 205 is relatively hard to prevent the clamping anti-slip block 217 from being squeezed and deformed. The second drainage tube 206 and the third drainage tube 209 are made of medical soft tubing, which facilitates drainage operations. The elastic force of the clamping spring 214 is less than that of the fixing spring 128. Therefore, when the drainage tube is subjected to a small external force, the clamping anti-slip block 217 first clamps and fixes the first drainage tube 205. When the pulling force is large, the fixing inclined block 130 will move relative to it, thereby realizing the detachment of the fixing sleeve 201. When the pulling force is small, the drainage tube can be clamped and fixed to prevent the drainage tube from falling off. When the pulling force is large, the drainage tube can be automatically pulled out to prevent the drainage tube from pulling the wound and causing the wound to tear, thus facilitating wound protection.
