An assembly for modifying airflow into a nasopharyngeal airway or trachea of a patient. A valve assembly having an inlet and an outlet attaches to a traditional airflow generator. A valve seal within the assembly is operable by a solenoid and is adapted to cycle in response to a programmable controller circuit wherein upon activation of both the airflow generator and the controller circuit, pressurized air from the airflow generator continuously enters the inlet but passes out of the outlet of the assembly only when the solenoid causes the valve seal to retract and to at least partially unblock the outlet such that the pressurized air is converted into a single, repeatable burst exiting the outlet thereby modifying the traditional airflow.

1. An assembly for modifying airflow into a nasopharyngeal airway or trachea of a patient, comprising: 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 two ends, an inlet and an outlet defined between each of said ends, and an interior feed tube, said valve assembly further comprising: a motor means signaled by said airflow disposed at one of said ends;an exit tube defined at the other of said ends;a valve seal within said interior feed tube connected to and operable by said motor means, said valve seal having defined therein a slot and further including an internal wall having a first side positioned beyond said slot, said valve seal adapted to cycle within said interior feed tube between said motor means and said exit tube and across said outlet;an exhalation slot defined on a different side of said internal wall for allowing exhaled air from said patient to re-enter said interior feed tube and proceed to said exit tube;a controller circuit connecting to said motor means for operating said motor means incrementally; and,wherein upon activation of both said airflow generator and said controller circuit, pressurized air from said airflow generator continuously enters said interior feed tube from said inlet but passes out of said outlet only when said motor means causes said valve seal to move in relation to said exit tube to at least partially unblock said outlet such that said pressurized air is converted into a single, repeatable burst exiting said outlet. 2. The assembly of claim 1, wherein said valve seal is a shaped member which seals against an inside surface of said interior feed tube. 3. The assembly of claim 1, wherein said valve seal is a sliding tube valve seal. 4. The assembly of claim 1, further comprising a return spring attached to said motor means for returning said valve seal to a rest position downstream from said outlet. 5. The assembly of claim 4, wherein said spring is attached solely to said motor means at an end thereof. 6. The assembly of claim 4, wherein said spring is positioned between said motor means and said valve seal. 7. The assembly of claim 6, wherein ventilation holes are defined through said interior feed tube beyond said outlet and in front of said motor means. 8. The assembly of claim 1, further comprising a drug delivery port connected to said inlet through which said pressurized air passes and into which an inhalable medication can be received. 9. The assembly of claim 1, wherein said valve assembly further includes a plunger rod extending said valve seal from said motor means. 10. The assembly of claim 1, further comprising an electrical switch connected to said outlet and to said controller circuit for charging said motor means. 11. The assembly of claim 10, further comprising a patient interface device connected to said switch for receiving said repeatable burst from said outlet. 12. The assembly of claim 1, further comprising a programmer linked to and encoding said controller circuit for adjusting said single, repeatable burst. 13. A method for modifying airflow into a nasopharyngeal airway or trachea of a patient, comprising the steps of: attaching a valve assembly having two ends, an inlet and an outlet defined between each end, and an interior feed tube to an airflow generator, wherein said airflow generator is a continuous blower producing a constant head of pressurized airflow into said valve assembly, said valve assembly including a solenoid-operated valve seal within said interior feed tube signaled by said airflow disposed at one of said ends; an exit tube defined at the other of said ends said solenoid-operated valve seal having defined therein a slot and further including an internal wall having a first side positioned beyond said slot; an exhalation slot defined on another side of said internal wall for allowing exhaled air from said patient to re-enter said interior feed tube and proceed to said exit tube;attaching said valve assembly to a patient;maintaining said airflow against said valve while said patient is exhaling and said valve is at rest;permitting said solenoid-operated valve seal to incrementally retract and allow said airflow to pass through said valve assembly and into said nasopharyngeal airway or trachea when said patient inhales; and,permitting exhaled air from said patient to re-enter said valve assembly and exit therethrough, as a result converting said constant head of pressurized airflow into an assisted burst of gas given during inhalation while allowing said patient to finish inspiration and exhale against lower or no pressure when said solenoid-operated valve seal is at rest. 14. The method of claim 13, further comprising the step of adjusting said assisted burst. 15. The method of claim 13, further comprising the step of delivering medication to said patient when said patient inhales. 16. The method of claim 13, further comprising the step of allowing said patient to intake ambient air when said valve is at rest.
