I.V. Filter apparatus

摘要

A filter apparatus is provided which is adapted for filtration of intravenous liquids and separates gas in the incoming intravenous liquid prior to delivering the filtered liquid to a patient. Incoming liquid is passed into a space within a filter holder, which space has a smaller portion that excludes gas due to surface tension forces and a larger portion where gas accumulates. A hydrophobic filter membrane is positioned adjacent the large portion of the space to permit passage of gas from the space. A hydrophilic filter membrane is positioned within the space to filter the liquid prior to administration to the patient.
