  • Cardiotomy reservoir
    Patent number: 4243531
    Abstract: A reservoir for blood or the like in which a rigid casing, having a perforated tubular member positioned within the casing and extending between the ends thereof, carries filtering and blood defoaming means. An improved configuration of inlet aperture means is provided. Also, the reservoir may define an upstanding central hump at its lower end, surrounded by an annular trough positioned at an acute angle to the axis of the perforated tubular member, for improved recovery of blood from the reservoir and improved calibration of the amount of blood in the reservoir.
