Portable device for rapidly inflating a bag

A portable device for rapidly inflating an inflatable bag, the portable device comprising:

• a central body including at least a first inlet and an air intake cylinder, the at least first inlet configured to be connected to a source of compressed gas at high pressure and the air intake cylinder configured to admit atmospheric air;
• an air ejection tube including a main portion and an end portion;
• wherein
• the main portion includes a first part and a second part, the first part having an opening defining an inlet of an air intake chamber configured to introduce the atmospheric air admitted via the air intake cylinder;
• and
• the end portion defines an outlet of the device and is configured to connect to the inflatable bag;
• an intermediate distribution chamber arranged between the first inlet and the air intake chamber, the intermediate distribution chamber connecting the first inlet with the air intake chamber;
• and
• a plurality of ejection holes located in a lateral wall of the air intake chamber, the plurality of ejection holes connecting said air intake chamber to the intermediate distribution chamber;
• wherein the first inlet is associated with a trigger mechanism configured to trigger the release and expansion of the compressed gas into the air intake chamber creating a depression which causes an inrush of atmospheric air through the air intake cylinder and the air intake chamber which is then driven into the second part and emerges from the end portion to inflate the inflatable bag.
