Claim 0:
1. A system for generating and dispensing an aerosol, the system comprising:
a generation device (12) configured to generate an aerosol by vaporizing a liquid with a pressurized gas from a pressurized gas source (36), the generation device (12) comprising a mixing unit (25) for mixing the liquid and the pressurized gas together;
a pressurizable container (45) configured to be loaded with the pressurized gas;
a liquid container (49) in the form of a compressible bag fluidly connected to the mixing unit (25) for supplying the mixing unit (25) with the liquid;
wherein the generation device (12) is adapted to utilize the pressurized gas to apply pressure to the pressurizable container (45) for expelling the liquid out of the liquid container (49) into the mixing unit (25); and
a medical instrument (10) including an aerosol outlet (16) for dispensing the aerosol generated by the generation device (12) onto or into a patient, wherein the medical instrument (10) is fluidically connected to the generation device (12) by an aerosol line (20) for supplying the aerosol to the medical instrument (10);
wherein the mixing unit (25) has a channel (26) with a constriction (27), wherein the channel (26) is configured to be connected to the pressurized gas source (36) upstream of the constriction (27) for supplying the pressurized gas to the mixing unit (25), wherein the liquid container (49) is connected to the channel (26) at the constriction (27) and/or downstream of the constriction (27), in order to convey the liquid out of the liquid container (49) into the channel (26) via a reduction of pressure in the channel (26) induced by the pressurized gas flowing through the constriction;
wherein the mixing unit (25) comprises a T-connector, wherein the constriction (27) is located at a first port of the T-connector, a second line (44) extends between a second port of the T-connector and the pressurizable container (45), and a third port of the T-connector is configured to be connected to the pressurized gas source (36), such that, in use, the pressurized gas source (36) supplies the constriction (27) with the pressurized gas, as well as provides the pressurized gas for applying positive pressure to the liquid.
