First-aid oxygen bag constant-pressure auxiliary device

The invention relates to a first-aid oxygen bag constant-pressure auxiliary device. The first-aid oxygen bag constant-pressure auxiliary device comprises a plate frame, a first extrusion mechanism and a second extrusion mechanism, wherein the plate frame is provided with a hollowed-out area used for accommodating an oxygen bag, and at least two positioning pieces which are positioned on the periphery of the hollowed-out area and are used for fixing the oxygen bag to the hollowed-out area; the first extrusion mechanism and the second extrusion mechanism are oppositely arranged on two horizontal sides of the plate frame, are positioned on the upper surface of the plate frame, and are used for extruding the oxygen bag in the hollowed-out area along the horizontal direction, and the extrusion direction of the first extrusion mechanism is opposite to that of the second extrusion mechanism. According to the first-aid oxygen bag constant-pressure auxiliary device provided by the invention, the first-aid oxygen bag is placed in the hollowed-out area of the plate frame and is fixed through the positioning pieces, and then the first extrusion mechanism and the second extrusion mechanism are adopted for extruding oppositely, so that the oxygen bag can permanently and steadily output oxygen, and the output pressure is constant; and in addition, the first-aid oxygen bag constant-pressure auxiliary device is simple in structure, and convenient to carry and use.
