A portable device for inflating an inflatable bag (60) comprises at least one inlet (46), for forming a fluid connection to a gas source. The gas source is attached or attachable to the inlet. The device further comprises an air intake chamber (32) which has an opening allowing atmospheric air to be admitted and an outlet intended to be connected to the bag to be inflated. The gas source comprises a first and at least a different second gas component. The first component is stored at least partially in liquid form; preferably, the first component is carbon dioxide. The gas source contains at least 10%, preferably more than 30% and most preferably more than 60% of the first component. The second component is gaseous or supercritical at a temperature of 243K and up to a pressure of 200 bar, preferably, the second component has a critical temperature below 243K. |
