Abstract
A lung simulator for partial simulation of functions of a lung, comprising at least one gas loop which is connected to a ventilator which is configured to convey a breathing gas into and/or out of the gas loop at least temporarily. The lung simulator comprises at least one device for setting the O2 concentration of the breathing gas in the gas loop, at least one device for setting the CO2 concentration of the breathing gas in the gas loop and at least one device for simulating a mechanical lung movement.
Claims20
A lung simulator for partial simulation of functions of a lung, wherein the lung simulator comprises at least one gas loop which is connected to a ventilator, the ventilator being configured to convey a breathing gas into and/or out of the at least one gas loop at least temporarily, and wherein the lung simulator further comprises
- (a) at least one device for setting an O2 concentration of the breathing gas in the at least one gas loop,
- (b) at least one device for setting a CO2 concentration of the breathing gas in the at least one gas loop, provided that (a) and (b) may be combined in a single device, and
- (c) at least one device for simulating a mechanical lung movement,
- the lung simulator further comprising a flushing gas course through which a flushing gas flows and (a) being a gas exchanger which is configured to set the O2 concentration of the breathing gas in the at least one gas loop by making use of flushing gas of the flushing gas course.
A lung simulator for partial simulation of functions of a lung, wherein the lung simulator comprises at least one gas loop which is connected to a ventilator, the ventilator being configured to convey a breathing gas into and/or out of the at least one gas loop at least temporarily, and wherein the lung simulator further comprises
- (a) at least one device for setting an O2 concentration of the breathing gas in the at least one gas loop,
- (b) at least one device for setting a CO2 concentration of the breathing gas in the at least one gas loop, provided that (a) and (b) may be combined in a single device, and
- (c) at least one device for simulating a mechanical lung movement,
- (b) in the at least one gas loop being a CO2 admixer and being arranged in a direction of flow in the at least one gas loop after (a) and being connected to a CO2 source, CO2 being introduced into the breathing gas in the at least one gas loop by the CO2 admixer, which CO2 admixer comprises at least one valve which is connected to the at least one gas loop.
A lung simulator for partial simulation of functions of a lung, wherein the lung simulator comprises at least one gas loop which is connected to a ventilator, the ventilator being configured to convey a breathing gas into and/or out of the at least one gas loop at least temporarily, and wherein the lung simulator further comprises
- (a) at least one device for setting an O2 concentration of the breathing gas in the at least one gas loop,
- (b) at least one device for setting a CO2 concentration of the breathing gas in the at least one gas loop, provided that (a) and (b) may be combined in a single device, and
- (c) at least one device for simulating a mechanical lung movement,
- at least one filter being arranged in the at least one gas loop, which at least one filter is configured to filter gas constituents at least partially.
