[0011] Furthermore, the liquid reservoir is a liquid storage bag or other container capable of holding liquid.

[0012] The beneficial effects of this utility model are:

[0013] This invention enables the main filter, which is in direct contact with the liquid requiring sterilization filtration, to undergo a pre-use sterilization integrity test before the sterilization filtration begins. This allows for timely detection of the main filter's condition before use without compromising its sterility or affecting subsequent sterilization filtration.

[0014] The design of the two main feed filters in this invention enables redundant filtration of feed liquids that require sterilization, thereby minimizing the risks associated with the sterilization filtration process.

[0015] The design of the gas filter, liquid filter, and storage bag of this utility model can ensure the sterility of the main liquid filter, the upstream and downstream spaces, during the integrity test after sterilization before use of any main liquid filter. Attached Figure Description
