Description

Technical Field

[0001] The utility model relates to the technical field of peritoneal dialysis pipelines, in particular to an anti-falling peritoneal dialysis pipeline. Background Art

[0002] Peritoneal dialysis (PD) uses the properties of the peritoneum as a semi-permeable membrane. The prepared dialysate is regularly and regularly infused into the patient's peritoneal cavity through a catheter by gravity. Due to the concentration gradient difference of solutes on both sides of the peritoneum, the solutes on the high-concentration side move to the low-concentration side (diffusion effect); water moves from the hypotonic side to the hypertonic side (osmotic effect). The peritoneal dialysate is continuously replaced to achieve the purpose of removing metabolic products and toxic substances in the body and correcting water and electrolyte imbalance.

[0003] At present, most peritoneal dialysis tubing is often used with plug-in connectors or pipe connectors. This connection method is simple and easy to use, but often lacks stability. Due to insufficient connection force, it is easy to fall off during use, which reduces the stability and safety of the connection.

[0004] Therefore, those skilled in the art provide an anti-dropout peritoneal dialysis tubing to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an anti-falling peritoneal dialysis pipeline. When the pipeline is in use, the connecting ring provided at one end of the first catheter and the second catheter enables the pipeline to be sleeved into the interior of the threaded barrel, and the internal thread of the threaded barrel is threadedly connected with the external thread of the threaded block, thereby realizing quick connection and providing a strong connecting force, which can effectively prevent the components from falling off and ensure the firmness and safety of the connection. At the same time, the conical blocks on both sides are clamped into the interior of the connecting ring and sealed with the rubber ring, which effectively prevents liquid leakage, ensures the sealing of the pipeline system, and improves work efficiency and safety.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A fall-proof peritoneal dialysis pipeline, comprising a connecting tube, two threaded barrels, a first catheter and a second catheter, both side end faces of the connecting tube are fixedly connected with connecting blocks, the outside of one side end faces of the two connecting blocks are fixedly connected with threaded blocks, the outsides of the two threaded blocks are provided with external threads, the middle of one side end faces of the two connecting blocks are fixedly connected with conical blocks, the inner walls of the two threaded barrels are provided with internal threads, one side end faces of the first catheter and the second catheter are fixedly connected with connecting rings, one side end faces of the two connecting rings are provided with rubber rings, the middle part of the outside of the connecting tube is provided with a fixing ring, the middle part of the upper end of the fixing ring is threadedly connected with an adjusting screw, and the lower end of the adjusting screw is rotatably connected with a pressing block;

[0008] Through the above technical solution, when the pipeline is in use, the connecting ring provided at one end of the first conduit and the second conduit enables it to be inserted into the threaded barrel, and at the same time, the internal thread of the threaded barrel is threadedly connected with the external thread of the threaded block, thereby realizing quick connection and providing a strong connection force, which can effectively prevent the parts from falling off and ensure the firmness and safety of the connection. At the same time, the conical blocks on both sides are clamped into the inside of the connecting ring and sealed with the rubber ring, which effectively prevents liquid leakage, ensures the sealing of the pipeline system, and improves work efficiency and safety.

[0009] Further, the two external threads are both threadedly connected to the internal thread;

[0010] Through the above technical solution, the threaded connection can generate a larger connection force, so that the connection parts can be more closely combined together, increasing the firmness and stability of the connection and reducing the risk of loosening or falling off of the connection.

[0011] Furthermore, the two rubber rings are sleeved on the outside of the conical block;

[0012] Through the above technical solution, the rubber ring can provide additional sealing pressure during connection to ensure that no leakage occurs at the connection, thereby effectively preventing leakage of liquid or gas and maintaining the normal operation of the system.

[0013] Furthermore, the two connecting rings are both located on one side of the inner part of the threaded barrel;

[0014] Through the above technical solution, the connecting ring located on one side of the inner part of the threaded barrel can be more firmly fixed therein and is not easily displaced or loosened by the external environment or force, which helps to ensure the reliability of the connection and reduce accidents or equipment damage caused by loose or failed connections.

[0015] Furthermore, the connecting pipe, the connecting block and the conical block are all provided with through holes and are in the same straight line;

[0016] Through the above technical solution, the setting of the through hole can ensure the formation of an unobstructed channel between the connecting pipe, the connecting block and the conical block, so that the fluid can pass through the entire system smoothly without causing poor flow or pressure loss due to blockage or bottleneck inside the pipeline.

[0017] Furthermore, the connecting pipe is made of polyurethane material;

[0018] Through the above technical solution, the polyurethane material has good flexibility and elasticity, can withstand different degrees of stretching and compression, and is not easy to break or deform, making the connecting pipe more durable during use.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model proposes an anti-falling peritoneal dialysis pipeline. Compared with the existing peritoneal dialysis pipeline, when the peritoneal dialysis pipeline is used, the connecting ring provided at one end of the first catheter and the second catheter enables the catheter to be sleeved into the inside of the threaded barrel, and the internal thread of the threaded barrel is threadedly connected with the external thread of the threaded block, thereby realizing quick connection and providing a strong connection force, which can effectively prevent the components from falling off and ensure the firmness and safety of the connection. At the same time, the conical blocks on both sides are clamped into the inside of the connecting ring and sealed with the rubber ring, which effectively prevents liquid leakage, ensures the sealing of the pipeline system, and improves work efficiency and safety.

[0021] 2. The utility model proposes an anti-falling peritoneal dialysis circuit. Compared with the existing peritoneal dialysis circuit, when the peritoneal dialysis circuit is in use, the adjusting screw at the upper end of the external fixing ring of the connecting tube is adjusted so that the pressure block can be moved, thereby adjusting the gap of the connecting tube, achieving precise control of the liquid flow rate, optimizing the effect of peritoneal dialysis, making the treatment more personalized, reducing the risk of complications, and improving the quality and safety of treatment.

The middle part of the upper end of the fixing ring 5 is threadedly connected with an adjusting screw 6, and the lower end of the adjusting screw 6 is rotatably connected with a pressing block 7. When the pipeline is in use, the connecting ring 11 provided at one end of the first conduit 9 and the second conduit 10 enables it to be sleeved into the inside of the threaded tube 8, and at the same time, the internal thread 14 of the threaded tube 8 is threadedly connected with the external thread 13 of the threaded block 3, so as to achieve quick connection and provide a strong connection force, which can effectively prevent the parts from falling off and ensure the firmness and safety of the connection. At the same time, the conical blocks 4 on both sides are stuck into the inside of the connecting ring 11 and sealed with the rubber ring 12, which effectively prevents liquid leakage, ensures the sealing of the pipeline system, and improves work efficiency and safety.

[0031] The two external threads 13 are both threadedly connected with the internal threads 14. The threaded connection can generate a larger connection force, so that the connection parts can be more closely combined together, which increases the firmness and stability of the connection and reduces the risk of loosening or falling off of the connection. The two rubber rings 12 are both sleeved on the outside of the conical block 4.

The setting of the through holes can ensure that an unobstructed channel is formed between the connecting pipe 1, the connecting block 2 and the conical block 4, so that the fluid can pass through the entire system smoothly without causing poor flow or pressure loss due to blockage or bottlenecks inside the pipeline. The connecting pipe 1 is made of polyurethane material, which has good flexibility and elasticity, can withstand different degrees of stretching and compression, and is not easy to break or deform, making the connecting pipe 1 more durable during use.

[0032] Working principle: When the pipeline is in use, the connecting ring 11 is inserted into the threaded tube 8, and the internal thread 14 of the threaded tube 8 is threadedly connected with the external thread 13 of the threaded block 3 to achieve a fast and strong connection, prevent parts from falling off, and ensure a firm and safe connection. At the same time, the conical blocks 4 on both sides are inserted into the connecting ring 11 and sealed with the rubber ring 12 to effectively prevent liquid leakage, ensure the sealing of the pipeline system, and improve work efficiency and safety. During the liquid delivery process, the adjustment screw 6 at the upper end of the external fixing ring 5 of the connecting tube 1 is adjusted, and the pressure block 7 is moved to adjust the gap of the connecting tube 1, so as to achieve precise control of the liquid flow rate, optimize the peritoneal dialysis effect, personalize treatment, reduce the risk of complications, and improve the quality and safety of treatment.
