Abstract
Description
Technical Field
[0001] The invention relates to the field of medical devices, and in particular to a safe multi-chamber peritoneal infusion bag. Background Art
[0002] In the current medical field, soft-packaged infusion products are key auxiliary tools in the treatment process. The continuous advancement of their design and manufacturing technology is crucial to improving treatment efficiency and patient safety. At present, fully automatic bag-making and filling machines have been widely used in the production process of different types of infusion bags, especially in the production of membrane dialysis fluids, and there are many technical means. However, the design of infusion bags for specific application scenarios such as peritoneal dialysis still faces a series of challenges and shortcomings, which are specifically manifested in the following aspects:
[0003] 1. Inconvenience and aseptic risk of medication plugs: Medication plugs are generally designed with aluminum-plastic combination covers. This structure usually requires a lot of force to open, which is particularly inconvenient for the elderly or patients who are not familiar with the operation. More importantly, the current medication plugs often do not have a sterile protection design. If they are not properly disinfected before use and directly exposed to the external environment, the risk of infection will be greatly increased. In addition, there is also a potential risk of starting infusion without adding medication due to misoperation.
[0004] 2. Limitations of a single infusion bag: Existing peritoneal dialysis infusion bags are mostly single-chamber designs. When a large amount of additional fluid needs to be added, the filling port often needs to be punctured multiple times. This not only increases the complexity of the operation, but may also damage the sealing of the filling port due to frequent punctures, causing leakage, which in turn leads to the destruction of the sterile environment and product failure.
[0005] In summary, the existing soft-packaged infusion bags have many shortcomings in terms of design rationality and sterility assurance. An innovative and safe multi-chamber peritoneal infusion bag design is urgently needed to solve the above problems, improve the safety and convenience of peritoneal dialysis treatment, and meet the diverse needs of clinical and home care.

[0062] In some embodiments of the present invention, reference Figure 1-5 The bag body 1 is provided with a weight-reducing groove 17, which can reduce costs, lighten deadweight, and facilitate use.
[0063] When the present invention is used, the isolation strip 3 between the adjacent infusion chambers 2 is opened before use, and it can be rolled forward from the tail to open it. After opening, the liquid is mixed. If it is necessary to add a compatible liquid, the valve sheet on the easy-break plug 6 is pulled off, and the liquid is added into the bag, and then mixed uniformly. After mixing, the safety chamber 4 is rolled forward to open the safety chamber 4, so that the liquid flows into the safety chamber 4. When it is used, the break plug 8 is broken, and the liquid is replaced after passing through the catheter, and the waste liquid is collected in the drainage bag 12.
[0064] This method is mainly to prevent the situation that when the liquid is not mixed, when the folding plug is broken, no liquid flows out and liquid replacement cannot be performed, its safety is greatly improved, and the safe use of medicines is effectively promoted.
