Patent ID: 7225807

Claim:
A system for administering an agent, comprising: a housing; an air source operable to provide positive pressure air; a nebulizer operable for receiving an agent from a vial coupled to the housing and converting the agent into an aerosolized agent; a mixing chamber to receive the aerosolized agent from the nebulizer and air from the air source; a release mechanism operable for releasing a quantity of the agent from the vial to the nebulizer, wherein the agent is converted into an aerosolized agent that is mixed with air from the air source in the mixing chamber; a prong with an inlet and an outlet, wherein the inlet is operable to receive the aerosolized agent and air mixture from the mixing chamber, and the outlet is operable to deliver the aerosolized agent and air mixture to a patient when the prong is inserted into a patient's orifice; an anti-backflow valve between the mixing chamber and the prong outlet, operable to permit flow from the mixing chamber to the prong, and to inhibit flow in a reverse direction; and a cooling chamber connected to the housing, the cooling chamber being adapted to receive the vial and being operable to maintain the agent at a selected temperature.
