ABSTRACT:
A blood reservoir adapted for use in an extracorporeal circulatory support circuit. The blood reservoir comprises a housing having a chamber for holding blood, an outlet in the housing for draining blood from the chamber, and first and second inlets for supplying venous blood to the chamber. The first inlet includes an first inlet tube extending from the top in the vertical-downward direction into the chamber, and the second inlet tube having a generally inverted U-shape extending into the chamber from the bottom of the chamber. A bowl-shaped fluid trap is positioned to trap fluid adjacent the downstream ends of the first and second inlet tubes. A novel fluid trap having an upwardly facing fluid trap portion, and an inverted bowl shaped portion is also disclosed.
