Oscillating positive respiratory pressure device

摘要

An oscillating positive respiratory pressure apparatus and a method of performing oscillating positive respiratory pressure therapy. The apparatus includes a housing having an interior chamber, a chamber inlet, a chamber outlet, an exhalation flow path defined between the inlet and the outlet, and a restrictor member rotatably mounted within the interior chamber. The restrictor member has an axis of rotation that is substantially perpendicular to the flow path at the inlet, and includes at least one blocking segment. Rotation of the restrictor member moves the at least one blocking segment between an open position and a closed position. Respiratory pressure at the chamber inlet oscillates between a minimum when the at least one blocking segment is in the open position and a maximum when the at least one blocking segment is in the closed position. By exhaling into the apparatus, oscillating positive expiratory pressure therapy is administered.

主权项

1. A respiratory treatment device comprising:
a housing having a chamber; a chamber inlet configured to receive air into the chamber; a chamber outlet configured to permit air to exit the chamber; a user interface in communication with the chamber inlet; a restrictor member mounted within the interior of the chamber, the restrictor member being movable relative to the chamber inlet between a closed position where the flow of air through the chamber inlet is restricted, and an open position where the flow of air through the chamber inlet is less restricted; a respiratory portal substantially aligned with the user interface, the respiratory portal being configured to receive an aerosol medicament from a nebulizer configured to deliver aerosol therapy; and, a one-way valve configured to permit the aerosol medicament to enter the respiratory portal; wherein the one-way valve is configured to remain closed for the administration of oscillating positive expiratory pressure therapy during a period of exhalation, and remain open for administration of aerosol therapy during a period of inhalation; and, wherein the restrictor member has an axis of rotation substantially perpendicular to a flow of air passing through the inlet and is rotatable through a complete revolution.
