A respiratory protection hood having a sealed flexible shell including a pressurized oxygen vessel provided with a calibrated output opening leading into the inside space of the flexible shell and a device for trapping at least one portion of the carbon dioxide exhaled by the user that includes a cartridge for adsorbing carbon dioxide having a perforated tube arranged around a volume of carbon dioxide absorbing material. At least one portion of the perforated tube being arranged around the volume of absorbent material in direct communication with the inside space of the hood.

Respiratory protection hood

Full hood respirator comprising a fluidtight flexible bag intended to be slipped over the head of a user, the flexible bag being provided with a transparent window and comprising, in its lower part, a rigid base element of annular overall shape intended to be positioned around the neck of the user, the base element comprising a tubular oxygen reservoir of pressurized oxygen provided with a calibrated outlet orifice opening into the internal volume of the flexible bag, characterized in that the base element comprises at least two rigid parts connected by an articulation, the two parts being movable relative to one another between a furled first position that prevents a head from entering the hood through the base element and an unfurled position of use that allows a head to enter the hood through the base element.

Full hood respirator

The invention relates to an air-separation device comprising a generally cylindrical casing housing a filtration element including a bundle of hollow oblong fibers forming a membrane, the longitudinal axis of the fibers being parallel to the longitudinal axis (A) of the cylindrical casing, said casing comprising an air inlet at a first end and an outlet for purified gas at a second end. The device comprises a member for maintaining the fiber bundle in the casing, characterized in that the maintenance member comprises at least one spring member disposed inside the casing, said spring member being loaded between an end-stop formed by the casing and a longitudinal end of the fiber bundle in order to maintain the fiber bundle longitudinally in place while allowing it to dilate and contract.
