Abstract
A device for delivering a compound to the olfactory region of the nasal cavity includes an actuator body and a tip configured to removably couple to the actuator body. The actuator body comprises a propellant channel in fluid communication with a propellant canister. The tip comprises a tip stem, a dip tube, a delivery channel, one or more puncture members, and an outlet orifice. The tip stem receives a compound container containing the compound and the compound container moves between a sealed state and an unsealed state. The one or more puncture members are each configured to puncture the compound container when the compound container is in the unsealed state. Propellant released from the canister travels through the propellant channel and into the punctured compound container, thereby contacting the compound and propelling the compound through the delivery channel and out the outlet orifice.
