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 comprises 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 being configured for connection to external gas supply ports to receive supplied oxygen and supplied nitrogen,
- wherein the gas supply control system comprises 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,
- wherein the gas supply control system comprises two or more gas output lines, and
- wherein the gas supply control system comprises a configuration allowing it to provide the supply gas output through one of the gas output lines and a configuration allowing it to provide the supply gas output through a plurality of the gas output lines.
A gas extraction system for an extracorporeal ventilation system comprising an exhaust gas removal line for connection to an external exhaust suction port to be provided, wherein the gas extraction system further comprises a sampling line and a connection merging the sampling line and the exhaust gas removal line to allow suction from the exhaust suction port to be applied to the sampling line, and wherein the sampling line comprises an outlet port for passively venting when not connected to the exhaust suction port.
An extracorporeal oxygenation system comprising an oxygenator and a gas supply control system, the gas supply control system being configured for connection to external gas supply ports to receive supplied oxygen and supplied nitrogen,
- wherein the gas supply control system comprises 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,
- wherein the gas supply control system comprises two or more gas output lines, and
- wherein the gas supply control system comprises a configuration allowing it to provide the supply gas output through one of the gas output lines and a configuration allowing it to provide the supply gas output through a plurality of the gas output lines.
