Abstract
A device for delivering a compound to the olfactory region of the nasal cavity includes an actuator body and a tip that removably couples to the actuator body. The actuator body comprises a propellant channel in fluid communication with a propellant canister. The tip comprises an exit channel, an inlet interface, one or more grooves, and an outlet orifice. The exit channel extends between a proximal end and a distal end of the tip. The inlet interface is positioned about a distal end of the exit channel, and the inlet interface couples to a compound container containing the compound. The grooves are positioned about the inlet interface and direct propellant from the propellant channel into the compound container, thereby agitating and entraining the compound in the compound container with the released propellant. The compound and the propellant then travel through the exit channel and out the outlet orifice.
