Abstract:
An assembly for modifying airflow into a nasopharyngeal airway of a patient. A valve assembly is adapted to attach to an airflow generator. A solenoid including a piston is mounted exterior to a feed tube. A butterfly valve is within the feed tube at the inlet. A pin is within the piston, and a shaft of the butterfly valve is bent to connect to the pin such that the solenoid can drive the butterfly valve. An exhalation valve is within the feed tube at the outlet, the exhalation valve adapted to slide axially within the feed tube and incrementally cover the outlet. Upon rotation of the butterfly valve, the exhalation valve thereby slides towards the mask side, wherein upon activation of both the airflow generator and a controller circuit, pressurized air from the airflow generator continuously enters the feed tube but is converted to a single, repeatable burst or rush.

Claim (Index 11):
An assembly for modifying airflow into a nasopharyngeal airway or trachea of a patient, comprising:\n a valve assembly adapted to attach to an airflow generator, wherein said airflow generator is a continuous blower of a type producing a constant head of pressurized air, said valve assembly having an airflow side and a mask side, an inlet and an outlet defined between said airflow side and said mask side, and a feed tube, said valve assembly further comprising:\n a solenoid mounted exterior to said feed tube, said solenoid including a piston working at said airflow side; \n a butterfly valve within said feed tube at said inlet, said butterfly valve including a valve shaft extending up towards said piston; \n an exhalation valve within said feed tube at said outlet; \n a piston hole defined within said piston; \n a pin loosely disposed vertically within said piston through said piston hole; \n said valve shaft bent to connect to said pin, wherein a rotational force is applied to said butterfly valve upon axial movement of said piston; \n a second drive rod having a second distal end and second proximal end, said second proximal end mounted to said solenoid on said mask side, said second distal end connected to said exhalation valve; \n a controller circuit connecting to said motor means for operating said linear actuator incrementally; and, wherein upon activation of both said airflow generator and said controller circuit, pressurized air from said airflow generator continuously enters said feed tube from said inlet but passes out of said outlet only when said solenoid causes said butterfly valve to move in response to inhalation of said patient and thereby simultaneously move said exhalation valve to at least partially block said outlet such that said pressurized air is converted into a single, repeatable burst.
