Abstract
Apparatus (20) for removing gas bubbles from a liquid to be infused to a patient wherein a gas trap (42) is located at the upper end of a vertical column (38, 40, 40a) having a lower inlet (44) and an upper outlet (56). A bracket (39) supports the column above the patient, and a bubble-separator (46, 39a, 47, 66, 63), positioned between the inlet and the outlet, causes gas bubbles to move toward the column axis as they rise so that they are captured in the gas trap (42). Liquid to be de-gasified is supplied from a vertical level above the column outlet and is delivered through the side outlet (56) to the patient below.
