DESCRIZIONE
A portable device for rapidly inflating an inflatable bag is disclosed, which comprises at least one inlet intended to be connected to a source of compressed gas, in order to allow this gas to expand into an air intake chamber, the inlet being associated with a mechanism that triggers the release of the compressed gas to the air intake chamber, the latter having an opening allowing atmospheric air to be admitted and an outlet intended to be connected to the bag that is to be inflated. The device further comprises an intermediate distribution chamber for the compressed gas, which chamber is arranged between the inlet and the air intake chamber in order to connect the one to the other, and ejection holes arranged so as to open into a lateral wall of the air intake chamber in order to connect the latter to the intermediate distribution chamber.
