Abstract
A circulatory heart model (30) is disclosed that is geometrically accurate with respect to corresponding anatomical structures (31, 91, 103, 112, 124). The model (30) provides a closed loop for providing flow through the major anatomical structures (31, 91, 103, 112, 124) corresponding to a modeled biological heart. The model (30) provides a means of pumping fluid through a closed loop flow circuit analogous to the circulatory system by gripping the base of the heart model (30) and squeezing with one's hand. The transparent quality of the heart model (30) enables flow visualization including visualization of anatomical valve function through representative valves (53, 60, 69, 80). The model (3) provides high educational, scientific, and/or amusement value in a device that is economical to produce.
