The Need of Slanted Side Holes for Venous Cannulae
Figure 1
(a) A venous cannula inserted in the inferior vena cava was calculated (left). A computational domain was constructed in 3D (right). (b) Illustrations of cannula: NSH and SA models. (c) Cross-sectional view of side holes; left: vertically upright (0°) side hole; middle: inclined side hole of angel θ created by rotating the upright side hole geometry; right: inclined side hole of angel θ created by distorting the upright side hole geometry. All illustrations are not to scale except the 3D computational domain in (a).
