Abstract:
An active agent delivery device, comprising:a tubular member that defines a lumen, said tubular member having a first end suitable for placement in a liquid and a second end suitable for placement in the mouth of the patient; an active agent in the form of discrete units disposed in said lumen; a mixing chamber spaced apart from the first end of said tubular member; a fluid passing active agent retainer, wherein said fluid passing active agent retainer prevents release of the active agent from the first end of said tubular member while permitting the liquid to enter said tubular member, said fluid passing active agent retainer being transportable toward said mixing chamber upon application of suction by the patient so that liquid and active agent are drawn into said mixing chamber; and means for providing turbulence, wherein said means for providing turbulence increases turbulence of the liquid drawn into said mixing chamber, wherein said means for providing turbulence is configured to prevent said fluid passing active agent retainer from being drawn into said mixing chamber.
