  • Display panel and controls for blood mixture delivery system
    Patent number: 5573502
    Abstract: A display panel for use with a blood mixture fluid delivery system, which system has mechanisms for infusing blood mixture fluid to a patient and for controlling characteristics of the fluid delivery system. The display panel includes a visible schematic representation of a blood mixture fluid flow path through the fluid delivery system and visible displays of two or more of the controllable characteristics of the fluid delivery system, which visible displays are positioned along the schematic representation of the blood mixture fluid flow path.

  • Cardioplegia delivery system
    Patent number: 5385540
    Abstract: A cardioplegia system for delivering cardioplegic solution to the heart during open heart surgery in cooperation with an extracorporeal blood circuit employing a heart/lung machine, includes a conduit diverting a portion of the blood flow from the heart/lung machine to a cardioplegia delivery line. A heat exchanger for controlling fluid temperature is provided in the cardioplegia delivery line. A first pump combines the blood from the conduit with a second fluid and delivers the combined flow into the delivery line leading to the heat exchanger. A control panel is operatively connected for adjusting the ratio of blood and second fluid delivered by the first pump and for adjusting the total volumetric rate of flow from the first pump.

  • Cardioplegia delivery system
    Patent number: RE36386
    Abstract: A cardioplegia system for delivering cardioplegic solution to the heart during open heart surgery in cooperation with an extracorporeal blood circuit employing a heart/lung machine, includes a conduit diverting a portion of the blood flow from the heart/lung machine to a cardioplegia delivery line. A heat exchanger for controlling fluid temperature is provided in the cardioplegia delivery line. A flat pump combines the blood from the conduit with a second fluid and delivery the combined flow into the delivery line leading to the heat exchanger. A control panel is operatively connected for adjusting the ratio of blood and second fluid delivered by the first pump and for adjusting the total volumetric rate of flow from the first pump.
