Apparatus and methods for pumping and oxygenating blood are provided that include a gas removal system. An integrated blood processing unit is provided in which a gas removal/blood filter, pump and blood oxygenation element are mounted within a common housing. The gas removal system includes a sensor mounted on the housing to sense the presence of gas, and a valve is operably coupled to the sensor to evacuate gas from the system when the sensor detects an accumulation of gas.

Micro-processor controlled active gas removal apparatus

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.

Tubing set for blood handling system and methods of use

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.

Extracorporeal blood handling system with automatic flow control and methods of use

Apparatus for oxygenating and pumping blood includes a housing defining a blood flow path including, in series, a gas collection plenum, a pump space and a blood oxygenation element. A pump disposed in the pump space is configured to draw blood from the gas collection plenum and propel blood from the pump space through a heat exchanger and the blood oxygenation element. The heat exchanger includes a heat exchange plate and a coolant space.

Integrated blood handling system having active gas removal system and methods of use

Apparatus and methods for removing gas from a blood handling system. A filter apparatus for monitoring and removing gas is provided comprising of a gas removal/blood filter, a sensor to sense the presence of gas, and a valve operably coupled to the sensor to evacuate gas from the apparatus when the sensor detects an accumulation of gas. When used with a previously known blood handling system, the present filter apparatus facilitates priming and the addition of additional blood handling elements during operation of the blood handling system.
