Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of auxiliary medical instruments, and specifically relates to a reverse-preventing and leakage-preventing fistula bag. BACKGROUND

[0002] In the field of medical care, especially for patients who need to have a fistula, how to effectively manage excrement has always been an important issue. Traditional fistula bag designs have some defects, such as easy leakage, inconvenience for excrement discharge and replacement, and possible irritation to the patient's skin. These defects not only affect the patient's quality of life, but also increase the workload of nursing staff.

[0003] In existing fistula bag technology, some designs use a single-layer bag structure, which has limitations in excrement storage and discharge. For example, the capacity of a single-layer bag is limited, and leakage can occur when excrement accumulates to a certain extent. In addition, the structure of a single-layer bag is not conducive to the smooth discharge of excrement, as they usually lack effective excrement outlet designs. These problems cause inconvenience to patients and nursing staff during use. SUMMARY

[0004] 1. The technical problem solved by the present scheme is to improve the leakage prevention performance of the fistula bag and ensure that the patient's excrement does not leak, thereby improving the patient's quality of life and the convenience of care. The technical solution adopted in this embodiment includes an inner bag for direct contact with the patient's skin, and the inner bag has at least one opening for excrement to enter; an outer bag located outside the inner bag for receiving excrement in the inner bag, and a closed space is formed between the outer bag and the inner bag to prevent excrement from leaking; the inner bag and the outer bag are made of waterproof material; the inner bag and the outer bag are connected by a sealing structure to ensure that the excrement is smoothly transferred from the inner bag to the outer bag. The beneficial effects produced by this embodiment are effective prevention of excrement leakage, reduction of the risk of odor and infection, and improvement of patient comfort. The working principle adopted in this embodiment is to use the inner and outer double-layer structure and sealing connection to form a closed excrement collection system, ensuring that excrement does not leak from the inner bag to the external environment.

[0005] 2. In the preferred implementation, the opening of the inner bag is provided with a flow guide structure to facilitate the passage of excrement, which is a tapered structure with a constricted shape. This design helps to guide excrement to flow smoothly from the inner bag into the outer bag, reducing splashing and leakage of excrement during transfer, and further improving leakage prevention performance.

[0006] 3. In the preferred implementation, the outer bag has at least one excrement outlet for excrement discharge. This design makes excrement discharge more convenient, and also facilitates cleaning and replacement of the fistula bag.

[0007] 4. In the preferred embodiment, the connection between the inner and outer bags is equipped with a test strip that detects leaks of excrement. This design can detect leaks in a timely manner, reminding patients or caregivers to replace the ostomy bag in time, avoiding long-term contact of excrement with the skin, and reducing the risk of skin irritation and infection.

[0008] 5. In the preferred embodiment, the ostomy bag also includes an accessory for fixing the ostomy bag to the patient's body. This design ensures that the ostomy bag is stably fixed in the right place during use, reducing the risk of leakage caused by movement or activity.

[0009] 6. In the preferred embodiment, the ostomy bag also includes an air valve for adjusting the pressure inside the bag to prevent leaks caused by excessive pressure. This design helps maintain the appropriate pressure inside the ostomy bag, avoiding leaks caused by pressure buildup, and also improves patient comfort.

[0010] The design of this anti-reverse and leak-proof ostomy bag aims to provide patients with a safe, hygienic, and easy-to-manage excrement collection system. Here is a detailed description of how this design achieves the anti-reverse and leak-proof function:

[0011] 1) Double bag structure: The ostomy bag is composed of an inner bag and an outer bag, with the inner bag directly contacting the patient's skin and the outer bag located outside the inner bag. This double-layer structure design ensures that excrement is first collected by the inner bag and then transferred to the outer bag through a sealing structure, preventing excrement from directly contacting the outside world and reducing the risk of leakage.

[0012] 2) Waterproof material: Both the inner and outer bags are made of waterproof material, which further prevents excrement from leaking and ensures the patient's skin is dry and comfortable.

[0013] 3) Sealing structure: The sealing structure between the inner and outer bags ensures that excrement can be smoothly transferred from the inner bag to the outer bag while preventing backflow and leakage. This sealing structure may include a zipper, Velcro, or other mechanical sealing methods to ensure tight closure.

[0014] 4) Flow guide structure: The opening of the inner bag is equipped with a flow guide structure, which helps guide excrement into the inner bag smoothly, reducing the possibility of overflow.

[0015] 5) Excrement outlet: The outer bag is equipped with at least one excrement outlet, which allows excrement to be discharged when needed while keeping the bag clean.

[0016] 6) Leak detection test strip: The connection between the inner and outer bags is equipped with a test strip that detects leaks of excrement, which can timely remind patients or caregivers to replace the ostomy bag to prevent leaks.

[0017] 7) Fixing attachment: The ostomy bag also includes an attachment for securing the ostomy bag to the patient's body, which helps maintain a stable position of the ostomy bag and reduces leakage caused by movement or activity.

[0018] 8) Vent valve: The ostomy bag also includes a vent valve for regulating the pressure inside the bag to prevent leakage caused by excessive pressure. This design helps maintain the balance of the environment inside the bag and reduces discomfort or leakage caused by gas accumulation.

[0019] In summary, the design of this anti-reverse leakage ostomy bag uses multiple mechanisms such as multi-layer protection, sealing structure, flow guide design, leakage detection, and pressure regulation to achieve the purpose of anti-reverse leakage and improve the quality of life of patients.
