摘要：
A respiratory therapy device including a housing and an interrupter valve assembly. The housing is sized for handling by a patient and defines a patient breathing passage extending from a patient end and through which a patient inhales and exhales air. The interrupter valve assembly is carried by the housing and includes a control port, a valve body, and a drive mechanism. Expiratory airflow is released from the patient breathing passage through the control port. The valve body is sized to at least partially obstruct fluid flow through the control port. The drive mechanism moves the valve body relative to the control port in response to the expiratory airflow such that the valve body repeatedly transitions between a position of maximum obstruction and a position of minimum obstruction relative to the control port to create an oscillatory positive expiratory pressure effect.
