SOLUTION DELIVERING APPARATUS FOR ARTIFICIAL HEART-LUNG MACHINE

摘要

PROBLEM TO BE SOLVED: To keep the whole flow rate const. even when the mixing ratio of blood and a medicinal solution is changed during delivery of a solution. SOLUTION: In a solution delivering apparatus for an artificial heart-lung machine wherein blood fed by means of a master side roller pump 3 and a medicinal solution fed by means of a sleeve side roller pump 4 are joined into a solution delivering line 8 by a set mixing ratio and are delivered, a whole flow rate setting means 12 for setting the whole flow rate of the blood and the medicinal solution to be joined, a mixing ratio setting means 13 for setting the mixing ratio of the blood and the medicinal solution and a computor for obtaining the flow rate of each pump from the whole flow rate and the mixing ratio and controlling each pump so as to move it by each flow rate, are provided.
