<p>A method and apparatus for preparing a cardioplegia mixture include the steps of combining first and second crystalloid solutions of different concentrations to establish a total volume flow rate of combined solutions. The flow rate of the first crystalloid solution is self-adjusted to equal the established total volume flow rate minus the established volume flow rate of the second crystalloid solution. The apparatus further includes means for self-adjustment of the flow rate of the first crystalloid solution to equal total the volume flow rate minus the established volume flow rate of the second crystalloid solution. The apparatus preferably includes a disposable tubing set for flowing, combining, and interconnecting the crystalloid solutions.</p> |
