An inhalation mask (1) for administering gas and any pharmaceutical preparation entrained by the gas, to a user, comprising a cup-shaped inner mask part (3) with an edge (4) adapted, in a first use position, to abut against the user's (2) face. The inner mask part (3) is connected by connecting means (5, 6, 7) to a gas inlet (8) and a gas exhaust means (9), adapted to exhaust the exhaled gas, and the mask (1) further comprises an outer mask part (11) which surrounds the inner mask part (3) and substantially extends from the edge (4) away from the user's (2) face and defines a gap (12) between itself and the inner mask part (3). The outer mask part (11) is connected to the gas exhaust means (9) for optionally generating a negative pressure in the gap (12) for exhausting an exhalation gas, and the mask (1) is characterised in that it further comprises a carrier device (13) adapted to be arranged on the user (2) and carry the mask (1) to enable a second use position in which the user's face (2) is substantially released from the inner mask part (3). |
