Modular home dialysis system - debubblers

摘要

An apparatus for removing air bubbles from blood is disclosed. The debubbler comprises front and rear covers (1002, 1008 respectively) with a fluid circuit board (1004) arranged between the two covers. A blood chamber is defined between cover (1002) and circuit board (1004) and an air chamber is defined between covers (1008) and circuit board (1004). A microporous membrane (1006) separates the blood and air chambers. A support means (1024) supports membrane (1006) from the air side of the membrane. A blood pressure sensor is provided between covers (1002, 1008). The debubbler has a blood inlet port (1022) and a blood outlet port (1020) for conducting blood to and from the blood chamber. An air port (1012) is provided in communication with the air chamber, to allow air passing through membrane (1006) to escape.
