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 and underlying said inlet;a valve seal connected to and operable by said motor means, said valve seal underlying said outlet and adapted to cycle within said interior feed tube between said motor means and across said outlet; 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. |
