Flow controller configurations for an active agent delivery device
摘要
The present invention is directed to an oral active agent delivery system comprising improved flow controllers. A hollow tubular member (10) containing the active agent formulation and having a fluid passing controller (14) is placed at one end (16) into a fluid and at a second end (18) into a patient's mouth. The active agent is delivered when the patient sips on the end of the chamber. The improved controllers prevent leakage of the active agent formulation.
