Abstract
Embodiments relate to a single-use device for delivery of medication into a nasal cavity. In an embodiment, the device includes a propellant canister containing a propellant capable of propelling the compound to the nasal cavity. The propellant canister is displaceable between an unactuated position and an actuated position within the device. The device further includes an actuation element with an actuation lever configured to displace the propellant canister from the unactuated position to the actuated position. The device also includes a puncture element positioned to puncture the propellant canister, which causes the release of the propellant from the propellant canister. The device further includes a dose holding chamber containing a unit dose of the compound. The dose holding chamber is positioned such that propellant flows into the dose holding chamber and causes the compound to be propelled from the dose holding chamber to the nasal cavity of the user.
