Abstract
A self-priming filter holder for filtration of intravenous liquids is provided and is formed of one or two housing portions sealed to a core portion. The core portion has one or two ribbed surfaces forming a plurality of flow paths sealed at one end and open at a second end and at least one channel preferably larger than the flow paths. The channel(s) is in fluid communication with the flow paths and an outlet. An inlet is provided to the interior of the housing portion(s) which are sealed from the ribbed surfaces by hydrophilic membranes. The housing portion(s) can be provided with gas vents sealed with hydrophobic membranes. Fluids pass through the flow paths in one direction and through the channel(s) in an opposite direction to remove gas from the flow paths and channels prior to use.
