Technical Field

[0001] This utility model relates to the field of dialysis fluid bag technology, specifically a peritoneal dialysis fluid outer bag with a double-layer protective structure. Background Technology

[0002] Peritoneal dialysis is a kidney replacement therapy used for patients with kidney failure. It removes waste products and excess water from the body by infusing and draining dialysate into the peritoneal cavity. A peritoneal dialysis fluid outer bag is an external protective bag used to enclose the peritoneal dialysis fluid, preventing contamination or damage during transportation or storage.

[0003] Existing peritoneal dialysis fluid outer bags are usually single-layer bags. To improve the protective properties of peritoneal dialysis fluid outer bags, in addition to edge reinforcement, the thickness of the peritoneal dialysis fluid outer bag also needs to be increased. Some are designed with multiple layers, but these are just nested bags, and the protective performance is not strong enough. Utility Model Content

[0004] The purpose of this invention is to provide a peritoneal dialysis fluid outer bag with a double-layer protective structure, in order to solve the problem mentioned in the background art that the current peritoneal dialysis fluid outer bags on the market improve protection through multi-layer settings, but only by nesting the bags together, and the protective performance is not strong enough.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a peritoneal dialysis fluid outer bag with a double-layer protective structure, comprising a peritoneal dialysis fluid outer bag body, wherein the peritoneal dialysis fluid outer bag body is provided with an inner bag body and an outer bag body, and a partition is provided between the inner bag body and the outer bag body, wherein the edges of the inner bag body and the outer bag body are jointly provided with an outer bag seal, and the edge of the inner bag body is also provided with an inner bag seal within the inner circle of the outer bag seal, wherein a tear opening is provided at the upper end of the inner bag body, and a hanging hole is provided at the outer bag seal.

[0006] Preferably, the inner bag and the outer bag are made of the same material and have the same thickness, and the internal volume of the inner bag is smaller than the internal volume of the outer bag.

[0007] Preferably, the gap between the inner bag seal and the outer bag seal is provided, and an overlapping area is provided between the inner bag seal and the outer bag seal.

[0008] Preferably, a protective air column is provided at the edge of the inner bag between the inner bag seal and the outer bag seal.

[0009] Preferably, the protective air column has a U-shaped structure and is located on the side and bottom of the inner bag.

[0010] Preferably, a sealing nozzle is pressed and fixed to the side of the outer bag, and the sealing nozzle is in communication with the partition.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: The double-layer protective peritoneal dialysis fluid outer bag provides dual protection through its double-layer structure, effectively preventing leakage. Simultaneously, protective air columns are installed on the sides and bottom of the inner bag, providing protection and shock absorption, while also facilitating easy removal of the peritoneal dialysis fluid outer bag. This double-layer protective peritoneal dialysis fluid outer bag forms a partition between the inner and outer bag bodies, with a sealing nozzle fixed to the outer bag body. This allows for connection to the partition, enabling the filling of gas or insulation material, thus enhancing the peritoneal dialysis fluid outer bag's protective properties and adding more functions, thereby improving its overall effectiveness.

[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 Figure 1-4This utility model provides a technical solution: a peritoneal dialysis fluid outer bag with a double-layer protective structure, including a peritoneal dialysis fluid outer bag body 1, an inner bag body 2 and an outer bag body 4 on the peritoneal dialysis fluid outer bag body 1. The inner bag body 2 and the outer bag body 4 are made of the same material and have the same thickness, and the internal volume of the inner bag body 2 is smaller than the internal volume of the outer bag body 4. This structure can prevent the outer bag body 4 from being compressed when storing peritoneal dialysis fluid inside the inner bag body 2, thereby enabling the outer bag body 4 to be externally protected. The inner bag body 2 and the outer bag body 4 constitute a double-layer protective structure. The peritoneal dialysis fluid outer bag 1 has a protective structure, with a partition 9 between the inner bag body 2 and the outer bag body 4. A sealing nozzle 8 is pressed and fixed to the side of the outer bag body 4, and the sealing nozzle 8 communicates with the partition 9. This structure allows gas or insulation material to be filled into the partition 9 when the cover of the sealing nozzle 8 is opened, providing stronger protection and more functions, thus improving the effectiveness of the peritoneal dialysis fluid outer bag 1. The edges of the inner bag body 2 and the outer bag body 4 share an outer bag sealing edge 5, with a gap between the inner bag sealing edge 3 and the outer bag sealing edge 5. An overlapping area is provided between the outer bag seals 5. This structure, by creating an overlapping area between the inner bag seals 3 and the outer bag seals 5, allows the inner bag body 2 and the outer bag body 4 to form a relatively sealed structure. Furthermore, the edge of the inner bag body 2 is also provided with an inner bag seal 3 within the inner circle of the outer bag seals 5. A tear slit 6 is provided at the upper end of the inner bag body 2. The tear slit 6 is designed primarily to facilitate quick and safe opening of the outer packaging by the user, while minimizing the risk of contamination. A hanging hole 7 is provided at the outer bag seal 5, which facilitates the fixation of the peritoneal dialysis fluid outer bag body 1. The inner bag body 2... Because of the protective air column 10 set between the inner bag seal 3 and the outer bag seal 5, this structure allows the outer ring of the inner bag body 2 to be reinforced with protective air column 10. At the same time, the protective air column 10 facilitates the removal of the peritoneal dialysis fluid outer bag body 1. The protective air column 10 forms a U-shaped structure and is located on the side and bottom of the inner bag body 2. This structure can provide buffer protection for the side and bottom of the inner bag body 2 through the protective air column 10. The inner bag body 2 forms a double sealing structure through the inner bag seal 3 and the outer bag seal 5, which can ensure the sealing effect.

[0016] Working principle: When using this double-layer protective peritoneal dialysis fluid outer bag, the peritoneal dialysis fluid outer bag body 1 first forms a double-layer bag structure through the inner bag body 2 and the outer bag body 4, giving the peritoneal dialysis fluid outer bag body 1 a double-layer protective structure. After the inner bag body 2 is sealed 3, a U-shaped protective air column 10 is set on the outside of the inner bag seal 3. The outer edge of the inner bag body 2 is then sealed together with the outer bag body 4 to form the outer bag seal 5. At the same time, the inner bag body 2 receives double sealing treatment, ensuring airtightness. For enhanced protection, a hanging hole 7 is provided on the outer bag seal 5 for securing the peritoneal dialysis fluid outer bag body 1. A tear 6 is provided at the upper end of the inner bag body 2 to allow for the filling of peritoneal dialysis fluid. A partition 9 is provided between the inner bag body 2 and the outer bag body 4. A sealing nozzle 8 is provided on the outside of the outer bag body 4 to connect the partition 9, allowing for the filling of gas or insulation material within the partition 9. This provides the peritoneal dialysis fluid outer bag body 1 with stronger protection and more functions, enabling it to perform a series of tasks.
