The sealing performance of disposable enema bags is one of its important quality indicators, directly related to the effectiveness and safety of use. Generally speaking, their sealing performance is good, mainly reflected in the following aspects:
1. Material and structural design: Enema bags are usually made of high-quality medical grade plastic materials, such as polyethylene (PE), which have good flexibility and sealing properties. The overall structure design of the bag is reasonable, and various parts are firmly connected through processes such as heat sealing or welding, reducing the possibility of leakage. For example, the connection between the bag body and the inlet and outlet ports has undergone special treatment to ensure a tight seal.
2. Sealing of inlet: The inlet is usually equipped with a sealing cap or plug, which can be opened when filling enema and tightly closed after filling to prevent liquid leakage. These sealing devices typically use threaded connections or bayonet designs to ensure the reliability of the seal. For example, some enema bags have a rubber gasket on the inlet sealing cover, which can further enhance the sealing effect and prevent liquid from seeping out from the inlet.
3. Sealing of outlet and flow control components: Valves or flow regulators are installed at the outlet to control the outflow rate and flow of enema solution. These components can effectively prevent liquid from flowing out when closed, ensuring good sealing performance. For example, common piston valves or plug valves can tightly fit the outlet when closed, preventing liquid leakage. Some of the better enema bags also adopt a dual sealing structure, further improving the sealing reliability of the liquid outlet.
4. Overall sealing test: During the production process, disposable enema bags undergo strict sealing tests. Common testing methods include pressure testing, vacuum testing, etc., which simulate actual usage to detect if there is any leakage in the enema bag. Only products that pass these tests can enter the market for sale, ensuring that the sealing performance of the product meets quality standards.
5. Sealing guarantee during use: When using disposable enema bags, as long as they are installed, filled, and used correctly, good sealing performance can generally be guaranteed. For example, when connecting components such as the anal canal, ensure a tight connection; Avoid excessive compression or collision of the enema bag during use to prevent damage to the sealing area due to external forces.
      Although the sealing performance of disposable enema bags is generally good, it is still necessary to carefully check the integrity and sealing of the product before use. If any damage or poor sealing is found, the use should be stopped immediately to ensure safety and effectiveness.
