  • Micro-processor controlled active gas removal apparatus
    Patent number: 7541000
    Abstract: 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.

  • Methods of use of a blood filter having a sensor for active gas removal
    Publication number: 20040228760
    Abstract: 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.
