Abstract

The present invention relates to a microbubble reducer for eliminating and/or removing bubbles of gas from a flow comprising non-Newtonian fluids, wherein the microbubble reducer comprises an inlet (10) at a low point, a curved duct means (4) comprising a gas outlet (5) at a high point, an outlet (6) at a low point, and a lumen (21) that runs through said inlet (10), said curved duct means (4), said gas outlet (5), and said outlet (6). Additionally, the present invention relates to methods for removing gas from a flow comprising non-Newtonian fluid(s) using the microbubble reducer, an apparatus comprising the microbubble reducer, and uses of the microbubble reducer pertaining to dialysis or similar treatments, inter alia hemodialysis, plasma exchange, for infusion of blood and other non-Newtonian fluids, and in a heart-lung machine.
