摘要：
A percussive pulsing therapy device configured for delivering pulsating or intermittent airflow to a patient device, such as a patient vest. The percussive pulsed air device may have an airflow generator for controlling amplitude of the percussive pulsed air and a pulse frequency control module for controlling frequency of the percussive pulsed air. In some embodiments, the pulse frequency control module may have a rotatable fan blade, such as a circular fan blade having one or more cutout portions. In some embodiments, the rotating fan blade may have one or more channels configured to redirect percussive pulsed air. Moreover, a percussive pulsed air device of the present disclosure may have a dampening element flowably coupled to an inlet of the pulse frequency control module. In some embodiments, at least one inlets of the pulse frequency control module may be arranged on a different airflow plane than one or more outlets.
