Respiratory therapy device oscillatory positive expiratory pressure including a bypass airflow.

摘要

Therapy device positive expiratory pressure oscillatory (1000) for installation in a ventilator circuit to induce an exhalation positive airway pressure oscillatory by a user, or to bypass the therapy without opening the ventilator circuit in which it is installed the device comprising: a flow tube of air (200) having an inlet opening adapted to be connected into a ventilator circuit for receiving expiratory air passed therethrough by a user receiving therapy or care respiratory, and an outlet opening adapted to be connected to the ventilator circuit for discharging the expiratory air passed through said inlet opening; control means airflow (100) placed in said air flow (200) for directing the flow of expiratory air received through said inlet opening in a first path of air movement for inducing a respiratory treatment elusuario or a second path of air movement which derives respiratory treatment; including said flow tube air (200) closure means (400) responsive expiratory air positioned in said first path of air movement and actuable between an open position and a closed in response to the pressure of expiratory air position passing through the same; and including said locking means responsive expiratory air output normally closed non-linear discharge opening in response to the presence of a predetermined pressure of expiratory air passing in said first path of air movement, and which closes in response to a decreasing rate predetermined air pressure through said non-linear discharge opening.
