Abstract:
1. A coronary perfusion device, comprising: a control input configured to receive a desired blood oxygen level of mixed blood in a mixed blood line; a venous blood supply input configured to receive deoxygenated blood from a patient; an oxygenated blood supply input configured to receive oxygenated blood from an oxygenator; the mixed blood line connected with said venous blood supply input and said oxygenated blood supply input and configured so as to output the mixed blood, the mixed blood comprising a mixture of deoxygenated blood from the venous blood supply input and oxygenated blood from the oxygenated blood supply input; a mixed blood sensor configured to measure blood oxygen levels in the mixed blood line; and a microprocessor that is programmed to receive data from said control input and said mixed blood sensor; wherein the microprocessor is programmed to control the mixing of blood as a function of the desired blood oxygen level; and wherein the mixed blood line provides coronary perfusion to the patient.
