Devices for de-aerating liquids flowing in medical liquid systems
First Claim
1. A device for de-aerating liquids flowing in medical liquid systems, in particular infusible solutions to be administered from a gravity-operated infusion set, said device comprising a hollow chamber through which the infusible solution flows, said chamber having a wall containing at least one aperture in which a liquid-tight air-permeable de-aerating unit is fitted, wherein the hollow chamber is cup-shaped in configuration and at the ends is provided with connecting sections with a first connecting section having an outlet passage running from the interior of the hollow chamber and a second connecting section having an inlet passage which opens into the hollow chamber, and wherein an outlet orifice from the inlet passage into the hollow chamber is orientated transversely to the longitudinal axis of the hollow chamber and leads the flow directly to the de-aerating unit.

Abstract
A device for de-aerating liquids flowing in medical liquid systems and in particular infusible liquids to be administered from a gravity-operated infusion set, comprises a hollow chamber through which the infusible solution flows and whose wall contains at least one aperture in which is inserted a liquid-tight, air-permeable de-aerating unit. By means of the device, air bubbles can be removed automatically from infusible solutions being administered.
