A blood filter device for separating gas bubbles from a flow of blood includes a filter medium in a lower body portion of the device through which the blood must flow before being directed through an outlet tube. An upper cap sealed to the top of the lower body portion includes a blood inlet tube into which a conical dispersion plate is projected so as to decrease the rate of flow of the blood. The rate of flow further decreases as it enters a debubbling chamber in the cap. A top wall of the cap defines a sloped and arched channel around the inlet tube adapted to direct released gas toward a vent tube at the uppermost extent of the sloped top wall.

In a blood filter device for removing gas bubbles from a flow of blood wherein said blood filter has a lower body including a filter medium and an outlet through which blood can flow and an upper body through which the blood passes en route to the lower body, wherein the improvement comprises a cap forming the upper body of the device and being hermetically sealed to the lower body and establishing fluid communication therebetween, said cap having a vertically oriented blood inlet tube, a debubbling chamber in communication with the inlet tube and with the lower body, a vent opening establishing communication between the debubbling chamber and an external environment, and a sloped upper wall of the debubbling chamber passing around the inlet tube, said sloped upper wall defining an inclined arched downwardly concave channel passing around the inlet tube, a lowermost edge of said inlet tube lying beneath the uppermost extent of said arched channel except at a single point location, and wherein the vent opening is positioned in the arched channel at the highest point thereof whereby gas bubbles released from the blood in the debubbling chamber will be encouraged to flow along said arched channel for removal from the device through said vent opening, said device further including a dispersion plate in alignment with the inlet opening for distributing the blood into said debubbling chamber.
