[0051] Example
[0052] This utility model provides a safe multi-chamber peritoneal infusion bag, referring to... Figures 1-5The bag includes a bag body 1, infusion chambers 2, isolation strips 3, safety chambers 4, filling port 5, easy-break stopper 6, inlet port 7, and breakable stopper 8. The bag body 1 is made of a flexible, transparent material, preferably a flexible film free of polyvinyl chloride (PVC) and plasticizers. It can be made of polypropylene, polyethylene, or a non-PVC composite film (TPE), possessing excellent formability and flexibility, high-temperature sterilization resistance, and good chemical stability. It reacts chemically with drugs and food, maintaining the stability and quality of the contents. Multiple infusion chambers 2 are located within the bag body 1. Preferably, the multiple infusion chambers 2 are arranged along the long side of the bag body 1 and connected to both ends of the bag body 1, used to hold the medication. The two infusion chambers 2 are separated by an isolation strip 3. Furthermore, by setting up multiple different infusion chambers 2, different types of medications can be filled, thus completely eliminating the mutual influence between the two liquids and effectively preventing premature mixing of medications, avoiding the risk of discoloration or ineffectiveness. The isolation strip 3 is formed by welding the upper and lower layers of the bag body 1; it is a semi-welded structure used to separate multiple infusion chambers 2. When external force compresses the infusion chambers 2, the upper and lower layers of the isolation strip 3 separate to connect adjacent infusion chambers 2. A safety chamber 4 is located on the bag body 1 and is connected by the isolation strip 3. Separated from the infusion chamber 2, this design prevents medication from entering the safety chamber before infusion and allows for the determination of the infusion order of medications in different infusion chambers 2 according to actual needs. The number of infusion ports 5 is the same as the number of infusion chambers 2, and each infusion port 5 is connected to one infusion chamber 2. This arrangement ensures that the liquids in different infusion chambers 2 do not interfere with each other. Preferably, its shape is cylindrical. An easy-break stopper 6 is connected to the infusion port 5 and includes an opening and a cap. The opening and cap are detachably connected and made of an elastic material. The infusion port 5 is designed for easy opening / closing by the user, facilitating drug injection. The infusion port is permanently sealed by the cap, preventing infection risks. The infusion port 5 can be closed when no infusion is being administered to the infusion chamber 2. The drainage port 7, connected to the safety chamber 4, is used to drain the drug solution. During use, simply squeezing the infusion chamber 2 opens the isolation strip 3 between the infusion chamber 2 and the safety chamber 4, allowing the drug solution to pass through the safety chamber 4 and finally enter the drainage port 7 for infusion. The break stopper 8, connected to the drainage port 7, is used to close the drainage port 7 when no drug is being administered.
[0053] In some embodiments of this utility model, reference is made to Figure 1 The aforementioned isolation strip 3 is Y-shaped, and there are two infusion chambers 2 with a liquid capacity of 500-1000mL. The two infusion chambers 2 are located on both sides of the infusion chamber 2, and the safety chamber 4 is located at the angle between the short sides of the isolation strip 3. This structure facilitates the uniform mixing of the drug solution in different infusion chambers 2. When using it, you only need to squeeze the end of the isolation strip 3 away from the safety chamber 4 to mix the drug solution, and then squeeze the end of the isolation strip 3 that is connected to the safety chamber 4 to realize the infusion.
[0054] In some embodiments of this utility model, reference is made to Figure 2 The aforementioned isolation strip 3 is elongated, and there are two isolation strips 3. Two infusion chambers 2 are arranged adjacent to each other, and one infusion chamber 2 and a safety chamber 4 are arranged adjacent to each other. Preferably, the end of the isolation strip 3 near the infusion port 5 and the inlet 7 has an arc-shaped structure to facilitate buffering between liquids and to facilitate opening during use.
[0055] In some embodiments of this utility model, reference is made to Figures 3-4 The aforementioned isolation strip 3 includes a first isolation strip 31 and a second isolation strip 32. The first isolation strip 31 is located between two adjacent infusion chambers 2 and is elongated. Preferably, one end of the first isolation strip 31 is arc-shaped. The second isolation strip 32 is L-shaped and is located between one infusion chamber 2 and the safety chamber 4. The second isolation strip 32 between the infusion chamber 2 and the safety chamber 4 can be squeezed apart first for infusion, and then the first isolation strip 31 between the two infusion chambers 2 can be squeezed apart for infusion. Alternatively, the first isolation strip 31 between the two infusion chambers 2 can be squeezed apart first for mixing, and then the second isolation strip 32 between the infusion chamber 2 and the safety chamber 4 can be squeezed apart for infusion.
[0056] In some embodiments of this utility model, reference is made to Figure 5 The aforementioned first isolation strip 31 can be multiple, preferably 2-3. This allows for the storage of more types of medications, preventing them from mixing and becoming inactive before infusion.
[0057] In some embodiments of this utility model, reference is made to Figures 1-5 The aforementioned infusion bag also includes a hand-held component, which includes a hanging hole 10 and a hand-held hole 9. The hanging hole 10 is provided on the edge of the bag body 1 for hanging the infusion bag. Preferably, there are two hanging holes 10, which are symmetrically arranged on the short side of the bag body 1. The hand-held hole 9 is provided on the edge of the bag body 1 for holding the bag. Its size is larger than that of the hanging hole 10 for easy holding. Preferably, it is located in the middle of the short side of the bag body 1.
[0058] In some embodiments of this utility model, reference is made to Figures 1-5 The above also includes a drainage component, which is connected to the break plug 8. When the break plug 8 is not broken, no liquid will flow out. At the same time, due to the design of the safety chamber 4, if the break plug 8 is broken in advance, no liquid will flow out. Since the safety chamber is not opened and the isolation strip 3 is not activated, no liquid will flow out, thus further improving safety.
[0059] The drainage assembly includes a drainage tube 11, a drainage bag 12, a fluid-conducting switch 13, and a fluid-conducting interface 14. One end of the drainage tube 11 is connected to the break plug 8, and the other end is connected to the drainage bag 12. Preferably, it is Y-shaped, with its long side connected to the break plug 8 and one end of its short side connected to the drainage bag 12, and the other end connected to the fluid-conducting switch 13. The drainage bag 12 is connected to the drainage tube 11. The fluid-conducting switch 13 is installed on the drainage tube 11. When the patient uses it, the switch is controlled according to its function, and the fluid flow rate can also be adjusted. The fluid-conducting interface 14 is connected to the fluid-conducting switch 13 and is used for replacement after the drainage bag 12 is full. The fluid-conducting interface 14 is designed to be sterile and is sterilized at high temperature during the manufacturing process using a water bath sterilizer with a sterilization temperature greater than 115 degrees Celsius, which can effectively ensure sterility. When in use, it can be directly connected to the connector placed in the abdominal cavity to achieve rapid replacement treatment.
[0060] In some embodiments of this utility model, reference is made to Figures 1-5 The aforementioned drainage assembly also includes a drainage bag hanging opening 15 and an annotation area 16. The drainage bag hanging opening 15 is provided on the drainage bag 12 for hanging the drainage bag 12; the annotation area 16 is fixed on the drainage bag 12 for marking the drainage bag operation instructions.
[0061] In some embodiments of this utility model, reference is made to Figures 3-4 The infusion port 5 and the infusion outlet 7 are set on the same side or opposite each other, and their positions can be adjusted according to actual needs, making the application range of this infusion bag wider.
[0062] In some embodiments of this utility model, reference is made to Figures 1-5 The bag body 1 has a weight reduction groove 17, which can reduce costs, reduce weight, and make it convenient to use.
[0063] Before use, open the isolation strip 3 between adjacent infusion chambers 2. This can be done by rolling it forward from the tail end. After opening, mix the liquids. If a compatible liquid needs to be added, remove the valve plate on the easy-break stopper 6, add the liquid to the bag, and then mix thoroughly. After mixing, roll the safety chamber 4 forward to open it, allowing the liquid to flow into the safety chamber 4. When ready for use, break the break stopper 8. The liquid will then undergo liquid replacement through the conduit, and waste liquid will be collected into the drainage bag 12.
[0064] This method is mainly to prevent situations where, if the stopcock breaks before the liquid is mixed, no liquid flows out and liquid replacement cannot be performed, thus greatly improving safety and significantly enhancing safe medication use.
[0065] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
