The invention relates to a flow controlled valve system. The flow controlled valve may be incorporated into a pre-filled, small-volume nebulizer assembly with a T-connector. The flow controlled valve allows different airflow characteristics in each direction. The flow controlled valve also facilitates breathing physiotherapy by creating different airflow resistances during inhalation and exhalation.

1. A respiratory patient interface with a flow controlled valve comprising: a patient interface component including a nebulizer port and a tube having a patient interface port and a valve port located at opposite ends of the tube, wherein the nebulizer port is between the patient interface port and the flow controlled valve, and the nebulizer port is operable to connect to a nebulizer;the flow controlled valve is located in the valve port and comprises a hole that passes through the flow controlled valve, allowing airflow through the hole in both a first direction and a second direction and a one-way valve that has an open configuration that allows additional airflow and a closed configuration that prevents the additional airflow through the flow controlled valve,wherein the one-way valve is in the open configuration when air moves in the first direction and is in the closed configuration when the air moves in the second direction. 2. The respiratory patient interface with the flow controlled valve of claim 1, wherein the one-way valve comprises: a valve gate operable to move between the open configuration and the closed configuration;a valve gate support, wherein the valve gate is attached to the valve gate support; anda valve seat, wherein the valve gate creates a seal against the valve seat in the closed configuration. 3. The respiratory patient interface with the flow controlled valve of claim 2, wherein the hole passes through the valve gate and the valve gate support. 4. The respiratory patient interface with the flow controlled valve of claim 1, wherein the one-way valve comprises a duckbill valve with lips operable to move between the open configuration and the closed configuration. 5. The respiratory patient interface with the flow controlled valve of claim 4, wherein the hole is defined by fixed corresponding hole portions in the lips. 6. A flow controlled valve assembly comprising: a tube having a first port and a second port located at opposite ends of the tube;a flow controlled valve in the second port comprising: a valve gate operable to move between an open configuration and a closed configuration,a valve gate support, wherein the valve gate is attached to the valve gate support,a valve seat, wherein the valve gate creates a seal against the valve seat in the closed configuration,an opening within the valve seat, wherein the valve gate controls airflow through the opening, wherein the valve gate is configured to allow the airflow to pass through the opening when the valve gate is in an open configuration and the opening is shut when the valve gate is in a closed configuration, anda hole that passes through the valve gate and the valve gate support wherein the valve gate is configured to allow air to pass through the hole in both a first direction and a second direction;wherein the valve gate is in the open configuration when the air moves in the first direction and the airflow passes through the opening and the hole, and wherein the valve gate is in the closed configuration when the air moves in the second direction and the airflow passes through the hole while the opening is shut. 7. The flow controlled valve assembly of claim 6, wherein the air moves from outside the tube to inside the tube through the flow controlled valve in the first direction and the air moves from inside the tube to outside the tube through the flow controlled valve in the second direction. 8. The flow controlled valve assembly of claim 6, wherein the air moves from inside the tube to outside the tube through the flow controlled valve in the first direction and the air moves from outside the tube to inside the tube through the flow controlled valve in the second direction. 9. The flow controlled valve assembly of claim 6, wherein the tube is a horizontal tube of a T-connector for a nebulizer and the first port is a patient interface port. 10. The flow controlled valve assembly of claim 9, wherein the flow controlled valve is configured to allow the air to move in the first direction during inhalation and allow the air to move in the second direction during exhalation. 11. The flow controlled valve assembly of claim 9, wherein the flow controlled valve is configured to allow the air to move in the first direction during exhalation and allow the air to move in the second direction during inhalation. 12. The flow controlled valve assembly of claim 6, wherein the valve gate support comprises a first strut extending from one side of the valve seat to an opposite side of the valve seat. 13. The flow controlled valve assembly of claim 12, wherein the valve gate support comprises a second strut on an opposite side of the valve gate, wherein the valve gate is held between the first strut and the second strut. 14. The flow controlled valve assembly of claim 6 further comprising a connector on an outside edge of the valve seat attaching the flow controlled valve to the second port of the tube. 15. The flow controlled valve assembly of claim 14, wherein the flow controlled valve is removable from the tube. 16. A flow controlled valve assembly comprising: a tube having a first port and a second port located at opposite ends of the tube;a flow controlled valve in the second port comprising: a duckbill valve having an open end and lips with side walls extending from the open end to the lips, the open end attaches to the second port of the tube and the lips are operable to move between an open configuration forming an opening and a closed configuration shutting the opening, and a hole in the duckbill valve, wherein the duckbill valve is configured to allow air to pass through the hole in both a first direction and a second direction;wherein the lips are in the open configuration when the air moves in the first direction and the air passes through the opening and the hole, and wherein the lips are in the closed configuration when the air moves in the second direction and the air passes through the hole while the opening is shut. 17. The flow controlled valve assembly of claim 16, wherein the tube is a horizontal tube of a T-connector for a nebulizer and the first port is a patient interface port. 18. The flow controlled valve assembly of claim 17, wherein the air moves in the first direction during inhalation and the air moves in the second direction during exhalation. 19. The flow controlled valve assembly of claim 17, wherein the air moves in the first direction during exhalation and the air moves in the second direction during inhalation. 20. The flow controlled valve assembly of claim 16, wherein the lips comprise a first lip and a second lip and the hole comprises a first hole portion fixed in the first lip and a second hole portion fixed in the second lip wherein the first hole portion and the second hole portion form the hole when the lips are in the closed configuration.
