  • Extracorporeal blood handling system with automatic flow control and methods of use
    Publication number: 20060009728
    Abstract: Apparatus for processing blood in an extracorporeal circuit with automatic flow control is provided in which error conditions are sensed and system operation is modulated responsive to the error conditions. The apparatus includes an extracorporeal blood processing system, at least one sensor that senses the presence or absence of gas or monitors venous pressure, and a controller operably coupled to the blood processing system to selectively reduce pump speed or to reconfigure flow paths within the blood processing system responsive to the sensor output.

  • Tubing set for blood handling system and methods of use
    Publication number: 20050256442
    Abstract: A tubing set for use with a blood handling system is described that decreases the priming volume and surface area of the blood handling circuit, lowering the risk of hemodilution, platelet activation, and hemolysis. The tubing set also reduces the number of manual connections required, and uses quick-disconnect couplings to facilitate connections between the various lines, and between the lines and the arterial and venous cannulae.
