A novel cardiotomy reservoir apparatus and method for use in an extracorporeal blood circuit which provides for the effective defoaming of blood that has been aspirated from a patient during surgery. The apparatus includes an outer receptacle, which is preferably generally cylindrical in shape, the receptacle having at least one inlet formed in the top thereof, an outlet formed in the bottom thereof, and a vent port. The receptacle contains a defoaming means which substantially occupies the entire interior volume of the receptacle, and which has an increasing density in the direction of blood flow through the receptacle. In addition, the cardiotomy reservoir of the present invention may be used with an external blood filter and the outlet of the reservoir receptacle has a valve formed therein to facilitate rapid and safe replacement of the external filter in the event that it becomes occluded. |
