Abstract
This invention provides a system for eliminating gas bubbles from a liquid. The liquid enters a chamber through an inlet port. The chamber has two outlet ports, the first bounded by a hydrophilic filter which passes liquid but not gas, and the second bounded by a hydrophobic filter which passes gas but not liquid. Entrapped gas bubbles entering the chamber pass through the hydrophobic filter to the atmosphere. The degassed liquid passes through the hydrophilic filter into tubing leading to the desired receptacle. This apparatus and method are particularly suitable for intravenous infusions and other medical applications in which the degassed liquid passes directly into the blood vessels of a patient.
