Abstract
A high volume filter for use in an I.V. or blood administration set. A double filter unit is formed by folding a length of filter material into two portions to form pocket members with tubular inlets placed in each. These components are then sealed into a length of plastic tubing with an additional tubular member to form a filter unit. In a preferred embodiment, the filter unit is formed integrally with a drip chamber.
