[0033] In Embodiment 1: As Figures 1 to 3 shown, a multifunctional peritoneal dialysis catheter fixing device described in the present utility model includes a fixing device body 1 and a catheter body 2. The fixing device body 1 contacts the human body. The catheter body 2 passes through the fixing device body 1 and extends into the human body. The fixing device body 1 includes an antibacterial layer 3 and a fixing layer 4. The antibacterial layer 3 is used to isolate bacteria. The antibacterial layer 3 is arranged on the side facing the human skin. The fixing layer 4 is used to keep the fixing device body 1 stable. The distance from the antibacterial layer 3 to the human skin is less than the distance from the fixing layer 4 to the human skin. The fixing device body 1 is provided with a penetration layer 5. The penetration layer 5 penetrates through the antibacterial layer 3 and the fixing layer 4. The size of the penetration layer 5 is at least larger than the diameter of the catheter body 2. Normal saline drips onto the skin of the human wound through the penetration layer 5.

[0034] In this embodiment, the side of the fixing device body 1 facing the human skin contacts the human skin. The catheter body 2 extends from the external environment to the human skin wound and then into the human body through the penetration layer 5. The penetration layer 5 being larger than the catheter body 2 can effectively keep the catheter body 2 passing through the fixing device body 1. At the same time, normal saline can effectively drip onto the human skin wound through the penetration layer 5. Further, the antibacterial layer 3 being arranged facing the human skin and cooperating with the penetration layer 5 can effectively reduce bacterial infection, thereby reducing the process of medical staff cleaning the wound.

[0035] In Embodiment 2: As Figures 1 to 3As shown, a multifunctional peritoneal dialysis catheter fixing device described in the present utility model includes that the antibacterial layer 3 includes an adsorption layer 6 and an isolation layer 7. The adsorption layer 6 is used for absorbing liquid, and the isolation layer 7 is used for isolating bacteria. The distance from the isolation layer 7 to the human skin is less than the distance from the adsorption layer 6 to the human skin, and a gap is maintained between the isolation layer 7 and the human skin. In this embodiment, the adsorption layer 6 can effectively absorb the saline from the penetration layer 5 to the wound of the human skin, thereby keeping the wound of the human skin clean and dry. The isolation layer 7 can effectively reduce the entry of bacteria from the external environment into the wound of the human skin. The gap between the isolation layer 7 and the human skin can effectively reduce the humidity between the fixing device body 1 and the human skin. At the same time, maintaining the gap can effectively reduce the secondary tearing injury to the human skin when the fixing device body 1 separates from the human skin, further improving the practicability of the fixing device body 1.

[0036] As a preferred implementation, on the basis of the above method, further, a collection layer 8 is provided between the isolation layer 7 and the penetration layer 5. The collection layer 8 is used for collecting the liquid at the wound of the human skin. One side of the collection layer 8 is communicated with the adsorption layer 6, and the other side of the collection layer 8 is in contact with the human skin. The side of the collection layer 8 facing the human skin is arranged around the periphery of the edge of the wound of the human skin. An air vent 9 is provided between the collection layer 8 and the penetration layer 5. The air vent 9 is used for communicating the collection layer 8 with the penetration layer 5. With this structural arrangement, the collection layer 8 can effectively collect the liquid at the wound of the human skin and guide it to the adsorption layer 6. The air vent 9 can effectively guide the liquid inside the penetration layer 5 to the collection layer 8. The collection layer 8 and the air vent 9 effectively reduce the humidity at the wound of the human skin, further improving the effect of cleaning the wound of the human skin with physiological saline.

[0037] As a preferred implementation, on the basis of the above method, further, the collection layer 8 and the penetration layer 5 are detachably connected and matched. With this structural arrangement, after dialysis, the scale accumulated after the long-term accumulation of physiological saline in the collection layer 8 can be effectively cleaned.

[0038] As a preferred implementation, on the basis of the above method, further, taking the human skin as the projection plane, the projection of the collection layer 8 covers the projection of the penetration layer 5, the center points of the collection layer 8 and the penetration layer 5 coincide, and the collection layer 8 can rotate around the center point of the penetration layer 5. With this structural arrangement, the liquid accumulates on the inner wall of the collection layer 8 under the action of gravity. The rotation of the collection layer 8 effectively reduces the accumulation of scale on one side of the collection layer 8, thereby reducing the blockage of the collection layer 8 caused by scale.

[0039] As a preferred embodiment, on the basis of the above manner, further, the penetration layer 5 and the fixing device body 1 are detachably connected and matched. With this structural arrangement, the detachable connection between the penetration layer 5 and the fixing device body 1 can effectively enable the penetration layer 5 to adapt to human skin wounds of different sizes, and further improve the effect of the penetration layer 5 in adapting to human skin wounds.

[0040] In Embodiment 3: As Figures 1 to 3 shown, a multifunctional peritoneal dialysis catheter fixing device described in the present utility model includes that the fixing layer 4 and the antibacterial layer 3 are detachably connected and matched. With this structural arrangement, it can effectively simplify the replacement of the adsorption layer 6 by medical staff, and further simplify the operation process of medical staff.

[0041] As a preferred embodiment, on the basis of the above manner, further, a loading layer 10 is arranged on the side of the fixing layer 4 facing away from the human skin, and the loading layer 10 is used to place a drainage bag. With this structural arrangement, it can effectively reduce the space occupied by medical supplies during peritoneal dialysis, and further improve the practicality of the fixing device body 1.

[0042] As a preferred embodiment, on the basis of the above manner, further, a fixing clip 11 is arranged on the side of the fixing layer 4 away from the human skin, and the fixing clip 11 is used to reduce the sliding of the catheter body. With this structural arrangement, the sliding of the catheter body 2 after fixation is further reduced, and the safety of the peritoneal dialysis process is improved.

[0043] As a preferred embodiment, on the basis of the above manner, further, the fixing device body 1 is provided with a fixing belt 12, and the fixing belt 12 winds around the human abdomen to reduce the sliding of the fixing device body 1. With this structural arrangement, the sliding of the fixing device body 1 during peritoneal dialysis can be effectively reduced, and the practicality of the present novelty in the actual use process is further improved.

[0044] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
