Abstract (en)

[origin: WO9848868A1] Blood volume in a soft-shell venous reservoir is measured for real-time display by ultrasonically measuring the distance between the walls of the reservoir bag at representative points and determining the volume of the bag by an interpolation based on the known shape of the reservoir bag as it expands and contracts.
