Nasal delivery device
First Claim
1. A breath-actuated nasal delivery device, comprising:
- a mouthpiece through which a user in use exhales to actuate the delivery device;
a nosepiece for fitting to a nostril of the user through which a substance is in use delivered;
a substance supply unit actuatable to deliver a dose of a substance through the nosepiece;
a loading unit operable to load the substance supply unit with an actuation force; and
a release mechanism for enabling actuation of the substance supply unit in response to exhalation by the user through the mouthpiece;
wherein the release mechanism comprises a locking unit which is movable between a locking configuration in which the substance supply unit is locked in a non-actuated position when loaded by the loading unit and a release configuration in which the substance supply unit is actuatable by the loading unit, and a trigger member for releasing the locking unit from the locking configuration to the release configuration in response to exhalation by the user through the mouthpiece and thereby enabling actuation of the substance supply unit.

32. A breath-actuated nasal delivery device, comprising:
-
a mouthpiece through which a user in use exhales to actuate the delivery device;
a nosepiece for fitting to a nostril of the user through which a substance is in use delivered and being in fluid communication with the mouthpiece;
a substance supply unit actuatable to deliver a dose of a substance through the nosepiece;
a release mechanism for enabling actuation of the substance supply unit in response to exhalation by the user through the mouthpiece; and
a flow-control mechanism disposed upstream of the trigger member to at least restrict an air flow to the trigger member such as to prevent actuation of the release mechanism on exhalation by the user through the mouthpiece where the delivery device is being improperly operated. - View Dependent Claims (33, 34, 35)

36. A release mechanism for enabling actuation of a substance supply unit, the release mechanism comprising:
-
a locking unit which is movable between a locking configuration in which the substance supply unit is locked in a non-actuated position and a release configuration in which the substance supply unit is actuatable; and
a trigger member for releasing the locking unit from the locking configuration to the release configuration in response to a gas flow thereat, wherein the trigger member includes a pivot pin about which the same is rotatable, which pivot pin is engaged by the locking unit when in the locking configuration such that the locking unit is moved from the locking configuration to the release configuration on rotation of the pivot pin. - View Dependent Claims (37, 38, 39)
