Abstract: A device for degassing gas bubbles out of a liquid comprises a housing having a liquid inlet, a liquid outlet and a gas bubble outlet. The housing includes a spiral wall defining a spiral flow path for the liquid and a hydrophobic membrane above the spiral wall and between the spiral wall and the gas bubble outlet. The spiral wall forces inward liquid entering the housing through the inlet into a spiral flow along the spiral flow path, and causes an upward flow of the gas bubbles toward the hydrophobic membrane. A method for degassing gas bubbles out of a liquid, e.g., blood, e.g., during hemodialysis, hemofiltration and hemodiafiltration, and use of such a degassing device in an extracorporeal circuit for degassing gas bubbles out of liquid, e.g., blood, e.g., during hemodialysis, hemofiltration and hemodiafiltration, are disclosed.
