ABSTRACT:
A device for separating gas bubbles from infusion fluids or human-body fluids by means of fluid-repellent, gas-permeable, microporous degassing elements with a casing, which has an inlet opening for the fluid to be degassed, an outlet opening for the degassed fluid, and at least one outlet opening for gas. The degassing element is disposed at least in the area of the casing in which gas bubbles occur, wherein the degassing element comprises at least one degassing capillary whose inner cavity is closed against the passage of fluid, and an outlet opening for the gas. Preferably, this device is used as an infusion filter, in which case a wettable, gas-impermeable microporous filter is additionally disposed in the casing. The wettable, gas-impermeable microporous filter may comprise filter capillaries, in which case the filter capillaries and the degassing capillaries can be disposed in such a way that they have only one common embedment.
