Respiratory device with a pneumatic conveying line

A respiratory device, wherein the respiratory device comprises a housing, a user interface, and a pneumatic unit;

• the pneumatic unit comprising at least one of each of a respiratory gas drive, a measuring unit, a control unit, and a sound unit;
• the pneumatic unit being designed as a pneumatic conveying line which forms a respiratory gas path from an appliance inlet to an appliance outlet of the housing, and at least one component of the pneumatic unit or the pneumatic conveying line being removable from the housing, and wherein 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 wherein the component having the highest heat buildup is at least one of the control unit, the respiratory gas drive, and a main circuit board.
