Abstract
A blood processing apparatus may include a heat exchanger and a gas exchanger. At least one of the heat exchanger and the gas exchanger may be configured to impart a radial component to blow flow through the heat exchanger and/or gas exchanger. The heat exchanger may be configured to cause blood flow to follow a spiral flow path.
Claims10
A blood processing apparatus comprising:
- a housing having a blood inlet and a blood outlet, the blood inlet extending into an interior of the housing;
- a heat exchanger core arranged within the housing and having a core aperture disposed near a first end of the housing such that blood passing from the blood inlet may flow through the core aperture to an exterior of the heat exchanger core;
- heat exchanger hollow fibers disposed about the heat exchanger core such that a heat exchanger fluid may flow through the heat exchanger hollow fibers and blood passing from the core aperture may flow across the heat exchanger hollow fibers;
- a cylindrical shell extending coaxially about the heat exchanger core and having an annular shell aperture disposed near a second end of the housing such that blood passing from the core aperture may flow to the annular shell aperture imparting a longitudinal blood flow component to the blood;
- and
- gas exchanger hollow fibers disposed about the cylindrical shell such that gases may flow through the gas exchange hollow fibers and blood passing from the annular shell aperture may flow across the gas exchanger hollow fibers.
