ABSTRACT:
An integral air inlet which in use admits filtered gases into a fluid container, especially infusion fluid containers, comprises a needle sealed to a housing which is closed by an air filter, the housing having disposed within it a duck bill valve which permits gas to flow from the outside and into the fluid container. The presence of the duck bill valve prevents fluid contacting the air filter thereby reducing the risk of bacterial contamination the fluid when gas is admitted.
