Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to the peritoneal dialysis tubing of a disposable peritoneal dialysis machine. Background Technology

[0002] Peritoneal dialysis tubing utilizes the peritoneum as a semipermeable membrane, using gravity to regularly and periodically infuse prepared dialysis solution into the patient's peritoneal cavity through the catheter. By continuously changing the peritoneal dialysis solution, metabolic waste products and toxic substances are removed from the body, and water and electrolyte imbalances are corrected.

[0003] Currently, the types of peritoneal dialysis tubing available on the market are relatively limited, mainly offering 5-liter and 2-liter capacities of peritoneal dialysis fluid, with varying tubing connection methods. Because the existing tubing connector designs cannot meet the different patients' needs for varying volumes of peritoneal dialysis fluid, this not only increases the workload of medical staff but also, in some local hospitals using imported 5-liter pressure-type automated peritoneal dialysis machines, often requires cutting the inlet tube of the 2-liter peritoneal dialysis fluid drainage bag and reconnecting it to the 5-liter peritoneal dialysis machine's tubing to accommodate it. However, this practice compromises the seal between the dialysis machine and the drainage bag, significantly increasing the risk of environmental bacterial infection. Peritonitis caused by peritoneal dialysis tubing infection can be fatal for patients, posing a significant safety hazard. Therefore, those skilled in the art have provided disposable peritoneal dialysis machine end-bag drainage tubing to address the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a disposable peritoneal dialysis machine end-bag flow tubing. Through optimized structural design, it achieves compatibility between 2-liter and 5-liter peritoneal dialysis fluid end-bag flow tubing and domestic and imported automatic peritoneal dialysis machines. Furthermore, compared to cutting and reconnecting, the tight fit of the connection method in this design provides better sealing, eliminating the risk of tubing infection. It is also simple to operate and safe to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disposable peritoneal dialysis machine end-bag flow tubing, comprising a main tube, a 2-liter peritoneal dialysis fluid end-bag flow bag body, and a 5-liter peritoneal dialysis fluid end-bag flow bag body. One end of the main tube is fixedly connected to a T-junction, and the two ends of the T-junction are fixedly connected to a first tube and a second tube. The upper end of the first tube is fixedly connected to a connector, and the upper end of the second tube is fixedly connected to an end-bag flow connector. A 2-liter peritoneal dialysis fluid end-bag flow bag catheter is inserted into the lower end of the 2-liter peritoneal dialysis fluid end-bag flow bag body, and a 5-liter peritoneal dialysis fluid end-bag flow bag catheter is inserted into the lower end of the 5-liter peritoneal dialysis fluid end-bag flow bag body. One end of the 2-liter peritoneal dialysis fluid end-bag flow bag catheter is fixedly connected to a 2-liter peritoneal dialysis fluid end-bag flow bag Luer connector, and one end of the 5-liter peritoneal dialysis fluid end-bag flow bag catheter is fixedly connected to a 5-liter peritoneal dialysis fluid end-bag flow plug body.

[0006] The above technical solution uses a three-way connector to connect a main tubing system, namely the first tubing and the second tubing. One end of each of these two tubing is connected to a terminal bag dispensing connector and a connecting plug, respectively. During use, the appropriate connector can be selected according to the patient's specific needs and connected to the tubing of domestic or imported peritoneal dialysis machines. Different tubing connection methods are used at the terminal bag dispensing connector and the connecting plug, so that the two interfaces provided by the 2-liter and 5-liter peritoneal dialysis fluid terminal bag dispensing fluid bags can be matched with the corresponding models of peritoneal dialysis machine tubing. This not only makes them clearly distinguishable but also achieves compatible connection for two models of peritoneal dialysis fluid, thereby expanding its applicability.

[0007] Furthermore, the 2-liter peritoneal dialysis fluid end bag flow bag Luer connector and connecting plug are threaded together and tightly fitted, while the 5-liter peritoneal dialysis fluid end bag flow plug body and end bag flow connector are directly inserted and tightly fitted.

[0008] The above technical solutions, through threaded fit design and straight insertion design, can not only make clear distinctions, but also make the connection better sealed than cutting and reconnecting, effectively preventing liquid leakage, while being easy to operate and safe to use.

[0009] Furthermore, the upper end of the end-bag flow connector is fitted with an end-bag flow liquid bag connector cap;

[0010] The above technical solution, by providing a cap for the end-bag peritoneal dialysis bag connector, can seal the port of the end-bag peritoneal dialysis connector when it is not in use, preventing external dust and other contaminants from entering the interior of the connector, ensuring the cleanliness of the connector interior, avoiding contamination of the peritoneal dialysis fluid during subsequent connection and use, and reducing the risk of infection for patients.

[0011] Furthermore, a plug cap is fitted onto the upper end of the connector.

[0012] The above technical solution, by providing a plug cap, can seal the plug port when the connector is not in use, preventing external impurities from entering the connector, maintaining the cleanliness of the plug, and ensuring that the quality of the peritoneal dialysis fluid will not be affected by plug contamination when connecting to other components, thus ensuring patient safety.

[0013] Furthermore, the Luer connector of the 2-liter peritoneal dialysis fluid end bag is fitted with a Luer connector protective cap;

[0014] The above technical solution, by incorporating a protective cap for the Luer connector, prevents the Luer connector from becoming contaminated when not in use, ensures the sealing and cleanliness of the Luer connector when connected to the plug, reduces the possibility of peritoneal dialysis fluid contamination, and protects the patient's health.

[0015] Furthermore, a protective cap for the 5-liter peritoneal dialysis fluid end-bag flow plug is fitted onto the main body of the 5-liter peritoneal dialysis fluid end-bag flow plug.

[0016] The above technical solution, by providing a protective cap for the 5-liter peritoneal dialysis fluid end-bag dispensing plug, can prevent external contaminants from adhering to the main body of the 5-liter peritoneal dialysis fluid end-bag dispensing plug when not in use. When connecting it to the end-bag dispensing connector in the future, it can ensure the reliability of the connection and the purity of the peritoneal dialysis fluid, thereby reducing the risk of infection.

[0017] Furthermore, both the outer walls of the first and second pipelines are equipped with water-stop clamps.

[0018] The above technical solution, by incorporating a water-stop clamp, facilitates the operator's control over the flow of liquid within the pipeline. When the water-stop clamp is closed, the pipeline is blocked, and the liquid cannot flow. When the water-stop clamp is released, the pipeline is unobstructed, and the liquid can flow normally.

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

[0020] 1. The disposable peritoneal dialysis machine end-bag flow tubing proposed in this utility model connects a main tubing system, namely the first tubing and the second tubing, through a tee. One end of each of these two tubing is connected to an end-bag flow connector and a connector plug, respectively. During use, the appropriate connector can be selected according to the patient's specific needs and connected to the tubing of domestic or imported peritoneal dialysis machines. Different tubing connection methods are used at the end-bag flow connector and connector plug, so that the two interfaces provided by the 2-liter and 5-liter peritoneal dialysis fluid end-bag flow bags can be matched with the corresponding models of peritoneal dialysis machine tubing, which not only makes it easy to distinguish them, but also achieves compatible connection of two types of peritoneal dialysis fluid, thereby expanding its application range.

[0021] 2. The disposable peritoneal dialysis machine end-bag drainage tubing proposed in this utility model effectively reduces the risk of infection for patients. This is because it eliminates the need to cut 2-liter or 5-liter dialysis tubing to install a new end-bag drainage tubing, avoiding the risk of tubing contamination, ensuring patient safety, and improving the efficiency and safety of the dialysis process. Furthermore, compared to cutting and reconnecting, the tight fit of this design provides better sealing, effectively preventing fluid leakage. This flexible connection method also allows medical staff to respond quickly to patients' treatment needs, reducing the potential risks associated with frequent changes to peritoneal dialysis bags.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figure 1-5This utility model provides a specific embodiment: a disposable peritoneal dialysis machine end-bag drainage tubing, including a main tube 1, a 2-liter peritoneal dialysis fluid end-bag drainage bag body 10, and a 5-liter peritoneal dialysis fluid end-bag drainage bag body 14. One end of the main tube 1 is fixedly connected to a T-junction 2, and the two ends of the T-junction 2 are fixedly connected to a first tubing 8 and a second tubing 9. The upper end of the first tubing 8 is fixedly connected to a connector 6, and the upper end of the connector 6 is fitted with a connector cap 7. By providing the connector cap 7, the connector port can be sealed when the connector 6 is not in use, preventing external impurities from entering the connector 6, maintaining the cleanliness of the connector, and ensuring subsequent connection with... When other components are connected, the quality of the peritoneal dialysis fluid will not be affected by plug contamination, ensuring patient safety. The upper end of the second tubing 9 is fixedly connected to a terminal bag peritoneal dialysis fluid connector 4. A terminal bag peritoneal dialysis fluid bag connector cap 5 is fitted onto the upper end of the terminal bag peritoneal dialysis fluid connector 4. By providing the terminal bag peritoneal dialysis fluid bag connector cap 5, the port of the terminal bag peritoneal dialysis fluid connector 4 can be sealed when not in use, preventing external dust and other contaminants from entering the interior of the terminal bag peritoneal dialysis fluid connector 4, ensuring the cleanliness of the connector interior, avoiding contamination of the peritoneal dialysis fluid during subsequent connections, and reducing the risk of patient infection. A 2-liter peritoneal dialysis fluid terminal bag peritoneal dialysis fluid bag catheter 11 is inserted into the lower end of the 2-liter peritoneal dialysis fluid terminal bag peritoneal dialysis fluid bag body 10. The lower end of the peritoneal dialysis end-of-life bag body 14 is connected to a 5-liter peritoneal dialysis end-of-life bag catheter 15. One end of a 2-liter peritoneal dialysis end-of-life bag catheter 11 is fixedly connected to a 2-liter peritoneal dialysis end-of-life bag Luer connector 12. One end of the 5-liter peritoneal dialysis end-of-life bag catheter 15 is fixedly connected to a 5-liter peritoneal dialysis end-of-life bag plug body 16. A set of tubing, namely the first tubing 8 and the second tubing 9, is connected to the main tubing 1 through a T-junction 2. One end of each of these two tubing is connected to an end-of-life bag connector 4 and a connecting plug 6, respectively. During use, the appropriate connector can be selected according to the patient's specific needs and connected to the tubing of the domestic or imported peritoneal dialysis machine. The tubing is connected to the end bag of peritoneal dialysis fluid, and different tubing connection methods are used at the end bag inlet 4 and the connector 6. This allows the two interfaces provided by the 2-liter and 5-liter end bag peritoneal dialysis fluid bags to be matched with the tubing of the corresponding models of peritoneal dialysis machines. This not only makes them clearly distinguishable but also achieves compatible connection for the two models of peritoneal dialysis fluid, thereby expanding its applicability. The outer walls of the first tubing 8 and the second tubing 9 are both equipped with water-stop clamps 3. By providing water-stop clamps 3, it is convenient for operators to control the flow of liquid in the tubing. When the water-stop clamp 3 is closed, the tubing is blocked and the liquid cannot flow. When the water-stop clamp 3 is released, the tubing is unobstructed and the liquid can flow normally.

[0031] Reference Figure 3-5The 2-liter peritoneal dialysis end bag drain bag's Luer connector 12 and connecting plug 6 are threaded together and fit tightly against each other. The 5-liter peritoneal dialysis end bag drain plug body 16 and end bag drain connector 4 are inserted directly and fit tightly against each other. The threaded and direct insertion designs clearly distinguish the components and provide better sealing at the connection point compared to cutting and reconnecting, effectively preventing liquid leakage. They are also easy to operate and safe to use. The 2-liter peritoneal dialysis end bag drain bag's Luer connector 12 is fitted with a Luer connector protective cap 13. The Luer connector protective cap 13 prevents... The Luer connector is designed to prevent contamination when not in use, ensuring a tight seal and cleanliness when connected to the connector plug 6. This reduces the possibility of peritoneal dialysis fluid contamination and protects the patient's health. The 5-liter peritoneal dialysis fluid end-bag flow plug body 16 is fitted with a 5-liter peritoneal dialysis fluid end-bag flow plug protective cap 17. By providing the 5-liter peritoneal dialysis fluid end-bag flow plug protective cap 17, external contaminants can be prevented from adhering to the 5-liter peritoneal dialysis fluid end-bag flow plug body when not in use. This ensures the reliability of the connection and the purity of the peritoneal dialysis fluid when subsequently connected to the end-bag flow plug 4, reducing the risk of infection.

[0032] Working principle: A set of tubing, namely the first tubing 8 and the second tubing 9, is connected to the main tubing 1 via a T-junction 2. One end of each of these tubing is connected to a peritoneal dialysis bag drain connector 4 and a connecting plug 6, respectively. During use, the appropriate connector can be selected according to the patient's specific needs and connected to the tubing of domestic or imported peritoneal dialysis machines. When using the 2-liter peritoneal dialysis fluid drain bag body 10 with the tubing of an imported or domestic peritoneal dialysis machine, i.e., the 2-liter peritoneal dialysis fluid drain bag catheter 11, the Luer connector protective cap 13 must first be opened to expose the 2-liter peritoneal dialysis fluid drain bag Luer connector 12, allowing the peritoneal dialysis fluid to flow smoothly from the 2-liter peritoneal dialysis fluid drain bag body 10 through the 2-liter peritoneal dialysis fluid drain bag catheter 11. Subsequently, simply thread the 2-liter peritoneal dialysis fluid drain bag Luer connector 12 and the connecting plug 6 together. Similarly, 5 The peritoneal dialysis end bag body 14 can also be connected to the tubing of imported or domestic peritoneal dialysis machines, namely the 5-liter peritoneal dialysis end bag tubing 15. When using it, the protective cap 17 of the 5-liter peritoneal dialysis end bag plug needs to be opened to expose the 5-liter peritoneal dialysis end bag plug body 16, so that the peritoneal dialysis fluid can flow out from the 5-liter peritoneal dialysis end bag plug body 14 through the 5-liter peritoneal dialysis end bag tubing 15. Afterwards, simply insert the 5-liter peritoneal dialysis end bag plug body 16 directly into the end bag connector 4. If both 2-liter and 5-liter peritoneal dialysis end bags are needed at the same time, through the design of the first tubing 8 and the second tubing 9, the 2-liter peritoneal dialysis end bag body 10 and the 5-liter peritoneal dialysis end bag body 14 can be connected to the main tubing 1 simultaneously, so that the use can be flexibly selected according to the specific needs of the patient during dialysis. Furthermore, different tubing connection methods are used at the end-bag peritoneal dialysis connector 4 and the connecting plug 6, allowing the two interfaces provided by the 2-liter and 5-liter peritoneal dialysis fluid end-bag peritoneal dialysis fluid bags to be matched with the corresponding models of peritoneal dialysis machine tubing. This not only provides clear differentiation but also achieves compatible connection for two models of peritoneal dialysis fluid, thereby expanding its applicability. In addition, it reduces the risk of patient infection because there is no need to cut the 2-liter or 5-liter dialysis tubing to install the new end-bag peritoneal dialysis tubing, avoiding the risk of tubing contamination, ensuring patient safety, and improving the efficiency and safety of the dialysis process. At the same time, compared to cutting and reconnecting, the tight fit of the connection method in this design provides better sealing and effectively prevents fluid leakage.

Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
