Abstract

The device, particular for extracorporeal blood circulation, as in hemodialysis, comprises a chamber 11 kept in an upright position, with an inlet 12 at the top, an outlet 14 at the bottom and a float 16 therein. When the liquid level is under a certain height, the float engages with the tapered inner wall 15 of the chamber outlet duct and preventing air bubbles from passing on downstream of the device. In a preferred embodiment the float member is housed within a filter 18 mounted within the chamber and has a tapered shape with a ballast to better engage with the bottom of the chamber and to give rise to an air- tight seal.
