    "Active breathing system"
    The present invention relates to an active breathing system for an aseptic suit arranged to be worn by a user.
    This type of system is commonly used in clean rooms. More precisely, the user puts on an aseptic suit and must be able to have an exchange with the surrounding environment in order to be able to breathe, while guaranteeing a sterile environment during manipulations carried out in white soil. Indeed, an increasingly frequent problem, with the improvement made to textile materials, operators suffer from drawbacks linked to an increase in the CO concentration inside the suit. There are portable aeration devices integrated into the suits, but the constraints linked to handling or cleaning difficulties or even from time to time of sterilization make them fragile, complicating logistics. Often, the air flows are theoretical and in the end, even used according to your manufacturers' criteria, the air is supplied in a very variable way if not at all.
    There are also mass suit type systems there too, implementation is heavy and handling is complicated.
    It is therefore known to use an aeration ventilation device which consists, using a fan, of directing the air inside the suit worn by the user. This type of device is generally complex and expensive. In addition, the ventilation system is heavy, which requires fixed placement in the clean room.
    Unfortunately, your current devices have an imposing size which is restrictive for the user who must be able to use this active breathing system while carrying out manipulations in the clean room.
