Abstract
According to this invention, there has been provided an inline final filter unit for the filtration and administration of intravenous fluids or the like wherein a flexible, nonporous intravenous tubing member contains microporous hollow fibres arranged within the tubular member parallel to the longitudinal direction of such tubing. The fibres are closed at one end and open at the opposite end. A flow blocking material is arranged around the fibres for blocking fluid flow through the flexible tubular member, other than through the material of said hollow fibres. At least one gas permeable hydrophobic fibre is arranged to extend into the tubing member in proximity to the microporous hollow filter fibres. One end of the hydrophobic fibre(s) is in communication with the atmosphere.
