The flow rate limitation device has a housing that has at least an inlet opening (13), at least an outlet opening (14), and a flow channel with a cross-section arranged between the inlet opening and outlet opening. A flexible wall extends along the flow channel and restricts the cross-section of the flow channel, thus limiting an inhalation volume flow during inhalation of therapeutic aerosols. The flexible wall has a control area of less than 100 square millimeters. |
