Passive respiratory therapy device

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