Abstract

A vented filter assembly 15 comprising a closed housing having a fluid inlet 44 and a fluid outlet 41. The housing includes an internal passage connecting the inlet and the outlet. A fluid filter is disposed within the passage between the inlet and outlet thereby defining an upstream pressure section between the inlet and the filter and a downstream pressure section between the filter and the outlet. A gas vent located in the housing is adapted to allow gas but not fluid to pass from the upstream section of the passage out of the housing. All fluid passing from the inlet to the outlet passes through the fluid filter. The filter is a pouch of a hydrophilic porous polycarbonate film with reinforcing layers, and a hydrophobic membrane attached below the vent transmits only gas thereto. The filter assembly is used to infuse parenteral liquids through a catheter assembly that includes a one-way valve 125.
