Abstract
An embodiment includes a cardioplegia delivery system having a console, controller, and disposables. The console, in conjunction with the disposables, combines blood from the heart-lung machine and crystalloid from the IV-bag in a specified ratio and then adds in a drug (arrest agent and/or additive). The electro-mechanical console incorporates a blood/crystalloid pump, temperature controllable water circulation system, pressure and temperature monitors, a sensor interface with the disposables, an arrest agent pump, an additive pump and ultra-sonic air detection sensors. The system monitors and controls the blood-crystalloid ratio, drug concentration, flow rate, pressure, temperature, and delivery route of the cardioplegia solution delivered to the patient. The system is a software-controlled system with a graphical user interface controller. The controller is utilized to initiate/stop cardioplegia delivery, monitor delivery parameters and view/save relevant case information and data.
