Abstract (en)

[origin: WO9823353A1] An extracorporeal, flow-through bubble trap chamber (320) has improved bubble separating abilities at high flow rates and generates smaller bubbles. The chamber contains chamber-defining top wall (330), side walls (334, 336) and bottom wall (332) plus blood inlet/outlet ports (322, 344) which extend through top and bottom walls (330, 332) to bring blood into and out of the chamber (320). The chamber (320) preferably has a height that is less than 1.6 times the longest horizontal dimension of the chamber (320). As a result of this, blood flow through the chamber (320) is substantially horizontal. A common flow inlet/outlet tube (350), closed with a central partition (340) is also present.
