Description

Technical Field

[0001] This utility model relates to the field of catheter fixation technology, specifically a catheter fixation device to prevent leakage from abdominal drainage tubes. Background Technology

[0002] Ascites is a common complication of cirrhosis at a certain stage, and its incidence is relatively high among patients with cirrhosis. An abdominal drainage tube is a medical device used for abdominal drainage. Its main function is to prevent the accumulation of fluid, blood, or other secretions in the abdominal cavity, thereby reducing the risk of infection. The catheter fixation device is a very common auxiliary tool in the use of the abdominal drainage tube.

[0003] During the process of fixing the abdominal drainage tube with a catheter fixation device, patients with cirrhosis have thinner abdominal walls and higher ascites pressure. Poor fixation of the drainage tube can easily lead to loosening, which in turn can cause the drainage tube to fall out and leak ascites. Large amounts of leakage can lead to the loss of nutrients such as protein, which can aggravate malnutrition and affect the body's recovery. It may also induce complications such as hepatic encephalopathy, thereby affecting the patient's recovery. Summary of the Invention

[0004] The purpose of this invention is to provide a catheter fixation device to prevent leakage from abdominal drainage tubes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a catheter fixing device for preventing leakage from abdominal drainage tubes, comprising a silicone waterproof sheet and a first fixing seat. The silicone waterproof sheet has a three-pronged opening groove inside, and the silicone waterproof sheet is circular. One of the openings in the three-pronged opening groove penetrates the radius. A first fixing seat is provided on one side of the outer wall of the silicone waterproof sheet, and a second fixing seat is connected to the middle of the outer wall of the first fixing seat. Both the first fixing seat and the second fixing seat have a catheter limiting groove at their center.

[0006] Preferably, the outer walls of the first fixing seat are connected to limiting members on both sides, and the first fixing seat and the limiting members form an integral structure. The first fixing seat has a locking groove on the side near the limiting members.

[0007] Preferably, the second fixing seat is connected to fixing members on both sides, and the second fixing seat and the fixing members form an integral structure. The second fixing seat has a fixing groove on the side near the fixing member.

[0008] Preferably, the fixing member extends into the engaging groove, and the limiting member extends into the fixing groove.

[0009] Preferably, the silicone waterproof sheet can tightly wrap the conduit, and the first fixing seat is made of silicone inside and hard plastic outside, so that the elasticity of the silicone and the rigidity of the hard material can work together.

[0010] Preferably, the edge of the limiting member is sealed with a 45-degree bevel, the first fixing seat and the second fixing seat are connected by a snap fastener, and the limiting member and the fixing member are arranged in a maze.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this catheter fixation device for preventing peritoneal drainage tube leakage, the silicone waterproof sheet wraps the catheter to form a physical barrier, effectively reducing leakage of exudate around the puncture point. By making the first fixation seat and the second fixation seat snap together, the first fixation seat and the second fixation seat wrap the catheter to achieve physical sealing, thereby forming a ring pressure band to apply uniform pressure, thereby sealing the catheter to prevent peritoneal effusion from aggravating the condition. In addition, the ring pressure band can prevent the catheter from slipping and achieve a fixing effect, significantly improving the stability of the catheter and the ability to control leakage. Thus, when using the catheter fixation device for peritoneal drainage tube, it plays a role in facilitating the sealing of the catheter and preventing peritoneal leakage. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5This utility model provides a technical solution: a catheter fixing device for preventing leakage from an abdominal drainage tube, comprising a silicone waterproof sheet 1 and a first fixing seat 3. The silicone waterproof sheet 1 has a three-pronged opening groove 2 inside, and the silicone waterproof sheet 1 is circular. One of the openings in the three-pronged opening groove 2 penetrates the radius. A first fixing seat 3 is provided on one side of the outer wall of the silicone waterproof sheet 1, and a second fixing seat 4 is connected to the middle of the outer wall of the first fixing seat 3. Both the first fixing seat 3 and the second fixing seat 4 have a catheter limiting groove 5 at their center. Limiting elements 6 are connected to both sides of the outer wall of the first fixing seat 3, and the first fixing seat 3 and the limiting elements 6 form an integral structure. A locking groove 7 is provided on the side of the first fixing seat 3 near the limiting elements 6. Fixing base 4 is connected to fixing parts 8 on both sides, and fixing base 4 and fixing parts 8 form an integral structure. Fixing base 4 has a fixing groove 9 on the side near fixing parts 8. Fixing parts 8 extend into the engaging groove 7, and limiting parts 6 extend into the fixing groove 9. The silicone waterproof sheet 1 can tightly wrap the conduit. The interior of fixing base 3 is made of silicone, and the exterior is made of hard plastic. The elasticity of silicone and the rigidity of hard materials can work together. The edge of limiting parts 6 is sealed with a 45-degree bevel. Fixing base 3 and fixing base 4 are connected by a snap-fit. Limiting parts 6 and fixing parts 8 are arranged in a maze. Both fixing base 3 and fixing base 4 are semi-circular. Hard plastic can play a role in shaping and fixing.

[0016] In practice, during the process of fixing the abdominal drainage tube with the catheter fixation device, because the silicone waterproof sheet 1 has a three-pronged opening groove 2 inside, and one of the openings in the three-pronged opening groove 2 penetrates the radius, the abdominal drainage tube is first inserted into the silicone waterproof sheet 1 through the three-pronged opening groove 2. At this time, the silicone waterproof sheet 1 wraps the catheter to form a physical barrier, which effectively reduces the leakage of exudate around the puncture point and reduces the risk of infection. In addition, the three-pronged opening structure adapts to different tube diameters through elastic deformation, avoiding catheter displacement or slippage caused by uneven pressure due to tape fixation. The mechanical distribution of the opening can disperse the pulling force of abdominal pressure fluctuations on the catheter, reducing the risk of puncture hole dilation. The slip-on design supports quick assembly and disassembly, which is convenient for nursing staff to change dressings or deal with sudden leakage. Next, the catheter is fitted into the catheter limiting groove 5 in the middle of the first fixing seat 3. Since the second fixing seat 4 is internally composed of silicone and externally made of rigid plastic, the silicone elastically wraps the catheter to form a dynamic buffer layer, thereby reducing the traction force caused by coughing or changes in body position. The rigid plastic can play a role in shaping and fixing. At this time, the synergistic effect of the elasticity of the silicone and the rigidity of the rigid material can both disperse local pressure and provide tensile strength. Then, the second fixing seat 4 is fitted into the first fixing seat 3, since the first fixing seat 3 is connected to the limiting member 6. The second fixation seat 4 is connected to the fixation piece 8. At this time, the limiting piece 6 is inserted into the fixation groove 9, and the fixation piece 8 is inserted into the engagement groove 7. At this time, the first fixation seat 3 and the second fixation seat 4 are circular, which then wraps the catheter to form a physical seal. The first fixation seat 3 and the second fixation seat 4 cooperate with each other to form an annular pressure band, which can effectively seal the catheter and also play a fixing role, thereby preventing peritoneal effusion from aggravating the condition. Then, the first fixation seat 3 and the second fixation seat 4 are attached to the silicone waterproof sheet 1, and finally, an outer ring adhesive dressing is added for fixation. Peritoneal effusion in patients leads to the loss of nutrients such as protein, exacerbating nutritional deficiencies and worsening the condition. Furthermore, significant effusion results in substantial fluid loss, potentially causing serious complications such as hepatic encephalopathy and electrolyte imbalances. Exudate also provides an excellent culture medium for bacteria, easily leading to skin infections around the drainage tube opening and even spreading abdominal infections, causing sepsis and other serious infections. Additionally, the need for frequent changes of clothing and bed linens due to effusion causes physical discomfort and psychological burden, affecting sleep and daily activities. This approach significantly improves catheter stability and effusion control, preventing the patient's condition from worsening and increasing the risk of infection. In summary, when using this catheter fixation device for preventing peritoneal drainage leakage, the catheter is first wrapped with a silicone waterproof sheet 1 to form a physical barrier, effectively reducing leakage around the puncture point. Then, fixation seat 3 and fixation seat 4 wrap the catheter to achieve physical closure, thereby forming a ring-shaped pressure band to apply uniform pressure, sealing the catheter to prevent peritoneal leakage from worsening the condition, and the ring-shaped pressure band can also prevent the catheter from slipping out, thus achieving a fixation effect, significantly improving the stability of the catheter and the ability to control leakage. Afterwards, fixation seat 3 and fixation seat 4 are attached to the silicone waterproof sheet 1, and finally, an outer ring adhesive dressing is added for fixation.
