Abstract: A nasal drug delivery device includes a pump that supplies drug containing fluid to a spray port. The pump is actuated by the user pressing on an externally accessible actuator. The actuation force from the user can be transmitted to the pump in a controlled fashion such that the pump sees a more consistent actuation force. Additionally or alternatively, the forward direction of the device's housing and/or the direction of actuator motion can be oriented with respect to the device's direction of spray so that the device can be conveniently held by a user for optimum results.

Abstract: A nasal drug delivery system and method of delivering a predetermined amount of medication to the nasal epithelia. The system including a container containing a substance to be delivered into the nasal passages of a user. The nasal drug delivery system also includes a nasal shaft extending from the drug delivery system for placement in or around the nose of user, the nasal shaft is in fluid communication with a valve of the container, and an oral shaft, extending from the drug delivery system for placement in the mouth of a user. The nasal drug delivery system also comprises a pressure activated diaphragm trigger, wherein upon application of pressure to the oral shaft triggers the release of a predetermined amount of a substance from the container to the nasal shaft.
