Abstract
A respiratory device comprises a housing, a user interface, and a pneumatic unit comprising at least one of each of a respiratory gas drive, a measuring unit, a control unit, and a sound unit and designed as a pneumatic conveying line forming a respiratory gas path from an appliance inlet to an appliance outlet of the housing. At least one component of the pneumatic unit or the pneumatic conveying line is removable from the housing. A cooling air path driven by a cooling fan is guided through the housing from a cooling air inlet to a cooling air outlet and at least the control unit, the respiratory gas drive and a main circuit board are arranged in the cooling air path in such a way that the component having the highest heat build-up during operation is arranged at an end of the cooling air path in a direction of flow of the cooling air path.
