Abstract
A gas supply control system for an oxygenator of an extracorporeal ventilation system is configured for connection to external gas supply ports for oxygen and nitrogen in the form of air and to create a supply gas output from oxygen and nitrogen. The gas supply control system includes two or more gas output lines and configured to supply the two or more gas output lines with the supply gas output. The flow rates through the gas output lines may be modulated differently.
Claims20
A gas supply control system for an oxygenator of an extracorporeal ventilation system, the gas supply control system comprising:
- a plurality of inlets for connection to external gas supply ports to receive supplied oxygen and supplied nitrogen;
- a gas supply device, in fluid communication with the plurality of inlets, having a configuration allowing it to create a supply gas output from a predetermined portion of supplied oxygen and from a predetermined portion of supplied nitrogen;
- two or more gas outlets from the gas supply device;
- and
- wherein the gas supply device further includes a configuration allowing it to switch between a mixed-gas supply mode and a high-oxygen supply mode, wherein in the mixed-gas supply mode the supply gas output is provided through one of the gas outlets and is created from supplied oxygen mixed with supplied nitrogen, and in the high-oxygen supply mode the supply gas output is provided through a plurality of the gas outlets and is created from supplied oxygen, wherein the supply gas output in the high-oxygen supply mode contains less nitrogen than in the mixed-gas supply mode.
An extracorporeal oxygenation system comprising:
- an oxygenator;
- and
- a gas supply control system, the gas supply control system including:
- a plurality of inlets for connection to external gas supply ports to receive supplied oxygen and supplied nitrogen,
- a gas supply device, in fluid communication with the plurality of inlets, having a configuration allowing it to create a supply gas output from a predetermined portion of supplied oxygen and from a predetermined portion of supplied nitrogen,
- two or more gas outlets from the gas supply device;
- and
- wherein the gas supply device further includes a configuration allowing it to switch between a mixed-gas supply mode and a high-oxygen supply mode, wherein in the mixed-gas supply mode the supply gas output is provided through one of the gas outlets and is created from supplied oxygen mixed with supplied nitrogen, and in the high-oxygen supply mode the supply gas output is provided through a plurality of the gas outlets and is created from supplied oxygen, wherein the supply gas output in the high-oxygen supply mode contains less nitrogen than in the mixed-gas supply mode.
