Abstract
A device (10) for removal of gas bubbles and dissolves gasses from fluids delivered into a patient during medical procedures is disclosed. A housing (20) having a number of gas permeable hollow fibers (50) passing therethrough is provided. The infused fluid is introduced through the interior lumens of the hollow fibers (50), and entrained or dissolved gasses are drawn through the fiber walls to the outer or shell side of the fibers. A vacuum may be drawn on the housing through a vent (32) to enhance gas removal. A passage (70) is optionally provided through the device to allow a tool or other device to be passed therethrough.
