Patent ID: 8075675

Claim:
Apparatus for extracting gas from fluid, comprising: a housing defining a fluid pathway and a gas pathway that is isolated from the fluid pathway, said housing having an inlet into the fluid pathway and an outlet from the fluid pathway, and an inlet into the gas pathway and an outlet from the gas pathway; at least one separation membrane in the housing separating the fluid pathway from the gas pathway, the at least one separation membrane comprising a fluorosilicone member that is substantially impermeable to the fluid and permeable to the gas, said separation membrane having a first side facing the fluid pathway and a second side facing the gas pathway and wherein the at least one separation membrane defines a generally flattened disk that is thicker at peripheral portion thereof and thinner at the center of the flattened disk; a porous membrane support facing the first side of the separation membrane; and wherein the fluid pathway includes the first side of the at least one membrane.
