Abstract

A fluid distribution module (1) for causing and monitoring the circulation of fluids from and to a patient through an extracorporeal blood treatment device, comprises a degassing device (11) connected to a connecting structure (10). The degassing device (11) comprises a first chamber (12) having a lower inlet (13) for a liquid and a second chamber (14) having an upper opening (79) closed by a hydrophobic membrane (78) and an outlet (15) for discharging the liquid. The connecting structure (10) has at least a first and a second conduits (20, 21) defined therein, wherein the first conduit (20) comprises a first end for connection to a discharge tube (7) from the treatment device and a second end connected to the inlet (13) of the first chamber (12) of the degassing device (11), and the second conduit (21) comprises a first end connected to the outlet (15) of the second chamber (14) of the degassing device (11) and a second end for connection to a blood return tube (6) to a patient.
