Abstract
An extracorporeal, flow-through bubble trap for blood lines having improved capabilities at high flow rates and with smaller bubbles. The bubble trap comprises a chamber-defining wall, plus a blood inlet and a blood outlet, each extending through the wall to communicate with the interior of the chamber. The blood outlet connects with the chamber interior adjacent the bottom thereof. The chamber interior has a height that is less than 1.6 times the longest horizontal dimension of the chamber interior. As a result of this, blood flow in the bubble trap chamber is substantially horizontal.
