Abstract
Nasal medication or drug delivery devices and methods for delivering adjustable or variable metered volumetric doses of medication or drugs to a nasal passageway of a user or patient.

Claims12
A nasal delivery device for delivering a medication or drug to a nasal passageway in a metered amount, comprising:
- a connection adapter having a receiving portion comprising a puncturing member;
- one or more sealing members presented on the connection adapter;
- a first chamber portion, comprising a first chamber, presenting a metered amount indicator and being fluidly coupled to the connection adapter;
- and a second chamber portion, comprising a second chamber, having a fluid atomizing tip, the second chamber fluidly coupled to the first chamber, and the second chamber allowing for free movement and positioning relative to the first chamber to a set position along the metered amount indicator to thereby establish a selected metered dose volume jointly defined by the first chamber and the second chamber;
- while maintaining a liquid seal therebetween.
A nasal dose delivery device comprising first and second telescoping dose container chamber portions configured to rotatably telescope to establish a selected dose volume and being further configured to slidingly telescope to deliver the selected dose volume;
- and
- further comprising a threaded slider ring interposed between the first and second telescoping dose container chamber portions and configured such that relative rotation between the first and second telescoping dose container chamber portions adjusts a dose volume jointly defined by the first and second telescoping dose container chamber portions and wherein the threaded slider ring is further configured to be lockable in a first position during relative rotation between the first and second telescoping dose container chamber portions and unlockable to allow telescopic sliding between the first and second telescoping dose container chamber portions to deliver the selected dose volume.
