Description

Technical Field

[0001] This utility model relates to the field of peritoneal dialysis catheter protection, and more specifically, to an anti-infection protective structure for peritoneal dialysis catheters. Background Technology

[0002] Peritoneal dialysis is one of the important methods for treating kidney failure. The use of peritoneal dialysis catheters is crucial during peritoneal dialysis. However, existing peritoneal dialysis catheters have some problems in their use, posing certain risks and inconveniences to patients.

[0003] Currently, the anti-infection performance of peritoneal dialysis catheters on the market needs improvement. Because peritoneal dialysis requires inserting the catheter into the patient's body, it comes into contact with the external environment and is susceptible to contamination by bacteria and other pathogens, leading to infection. Infection not only affects the effectiveness of peritoneal dialysis but can also trigger a series of serious complications, threatening the patient's health.

[0004] Furthermore, existing peritoneal dialysis catheters have shortcomings in connection stability. The connection points are prone to loosening or detachment, affecting the normal progress of dialysis. At the same time, the protective performance of the dialysis catheters is not ideal, failing to effectively isolate external sources of infection and increasing the risk of infection.

[0005] In addition, the existing peritoneal dialysis catheters are not very effective at filtering harmful substances, which may result in the fluid entering the patient's body not being pure enough, affecting the treatment effect and the patient's health.

[0006] The shortcomings of existing technology: Current peritoneal dialysis catheters lack effective antibacterial measures, making it difficult to effectively inhibit bacterial growth and reproduction, which easily leads to infection. The connection points of the peritoneal dialysis catheters are not designed reasonably, making them prone to loosening or detachment, affecting the smooth progress of dialysis.

[0007] Existing peritoneal dialysis catheters are ineffective at isolating external sources of infection, providing insufficient protection for patients and increasing the risk of infection. Furthermore, existing catheters have limited filtration capacity for harmful substances, potentially allowing impure fluids to enter the patient's body, affecting treatment outcomes and patient health. Therefore, we propose an improved anti-infection protective structure for peritoneal dialysis catheters. Utility Model Content

[0018] 3.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1: Please refer to Figures 1-4 An anti-infection protection structure for a peritoneal dialysis catheter includes a peritoneal dialysis catheter insertion tube 1, which is connected to a conical connecting tube 101. The conical connecting tube 101 is connected to a catheter retaining ring 102, which is connected to an antibacterial protective catheter sheath 2, and the antibacterial protective catheter sheath 2 is connected to a sterile protective cap 3.

[0031] A groove 103 is provided at the connection between the tapered connecting tube 101 and the insertion cannula retaining ring 102. An anti-infection isolation ring 4 is linearly arranged on the sterile protective cap 3. An antibacterial coating sleeve 5 is provided at the connection between the anti-infection isolation ring 4 and the sterile protective cap 3. An antibacterial filter element 6 is provided at the end of the sterile protective cap 3. The antibacterial filter element 6 includes an activated carbon filter 601, a graphene filter layer 602, and a filter membrane layer 603. The graphene filter layer 602 is provided on the side of the activated carbon filter 601, and the graphene filter layer 602 is connected to the filter membrane layer 603. An anti-infection fastening ring 7 is provided on the side of the anti-infection isolation ring 4.

[0032] The working principle of the peritoneal dialysis catheter's anti-infection protection structure is as follows: The peritoneal dialysis catheter 1 is inserted into the patient's body for peritoneal dialysis. The peritoneal dialysis catheter 1 is connected to the conical connecting tube 101 to achieve fluid transfer. The conical connecting tube 101 is connected to the catheter retaining ring 102, and the groove 103 at the connection helps to enhance the stability of the connection.

[0033] The cannulation retaining ring 102 is connected to the antibacterial protective catheter sheath 2, which provides a certain degree of antibacterial protection. The antibacterial protective catheter sheath 2 is connected to the sterile protective cap 3 to further enhance protection. The anti-infection isolation rings 4 arranged linearly on the sterile protective cap 3, as well as the anti-infection fastening rings 7 on the sides of the anti-infection isolation rings 4, can enhance the isolation and protection against external sources of infection.

[0034] The antibacterial coating sleeve 5, which is installed at the connection between the anti-infection isolation ring 4 and the sterile protective cap 3, can inhibit the growth and reproduction of bacteria and improve the protective effect.

[0035] The antibacterial filter element 6 at the end of the sterile protective cap 3 consists of an activated carbon filter 601, a graphene filter layer 602, and a filter membrane layer 603. The activated carbon filter 601 has an adsorption function, which can adsorb some harmful substances. The side graphene filter layer 602 has good filtration and antibacterial properties. The graphene filter layer 602 is connected to the filter membrane layer 603 to further improve the filtration effect and effectively prevent bacteria and other harmful substances from entering the peritoneal dialysis catheter.

[0036] In summary, this peritoneal dialysis catheter anti-infection protection structure achieves anti-infection protection for the peritoneal dialysis catheter through the synergistic effect of its various components, reducing the risk of infection and improving the safety and effectiveness of peritoneal dialysis.

[0037] The workflow of the peritoneal dialysis catheter's infection protection structure is as follows: First, the peritoneal dialysis catheter 1 is inserted into the patient for peritoneal dialysis. The peritoneal dialysis catheter 1 is connected to the conical connecting tube 101 to ensure smooth fluid delivery.

[0038] The tapered connecting tube 101 connects to the insertion cannula retaining ring 102, and the groove 103 at the connection point enhances the stability of the connection. The insertion cannula retaining ring 102 connects to the antibacterial protective catheter sheath 2, providing a certain degree of antibacterial protection for the peritoneal dialysis catheter. The antibacterial protective catheter sheath 2 connects to the sterile protective cap 3, further enhancing the overall protective performance. During use, the antibacterial filter element 6 at the end of the sterile protective cap 3 plays a role. When the liquid passes through the antibacterial filter element 6, it first passes through the activated carbon filter 601, and the adsorption effect of the activated carbon filter 601 can remove some harmful substances.

[0039] The liquid then passes through the side graphene filter layer 602, which has excellent filtration and antibacterial properties, further filtering and inhibiting bacteria. Finally, the liquid passes through the filter membrane layer 603 connected to the graphene filter layer 602, further improving the filtration effect and ensuring that the liquid entering the peritoneal dialysis catheter is relatively pure, reducing the risk of infection. Simultaneously, the linearly arranged anti-infection isolation rings 4 on the sterile protective cap 3, and the anti-infection fastening rings 7 on the sides of the anti-infection isolation rings 4, enhance the isolation and protection against external sources of infection.

[0040] The antibacterial coating sleeve 5 at the connection between the anti-infection isolation ring 4 and the sterile protective cap 3 can inhibit the growth and reproduction of bacteria and improve the overall protective effect.
