Case Shows

The common medical bag instruments include infusion bag, urine bag, blood-pressure cuff, oxygen bag and blood bag, which are generally used to hold liquid or gas.




Bag products are generally made of PVC materials and processed by high cycle heat sealing machine. If its air leakage is not good, it will cause gas or liquid leakage, which may affect the use experience, or threaten human life safety, causing immeasurable losses.


How do we test whether the medical bag leaks?


Air leak test process


Testing equipment: HC classic series air leak tester machine



Detection method: direct detection is adopted with customized molds and tooling as customer’s need. Place the product to be tested on the fixture, and press the start button to start the test.




Test parameters: inflation 15Kpa, time 10s, voltage stabilization 10s, test 5s. In this process, if the leakage exceeds the upper limit of 50pa, the program triggers an alarm or NG signal appears, that is, the air leakage of the product to be tested is unqualified, and it is a defective product.
