Patent attributes
A drinking actuated device for delivering a substance to the nasal cavity of a subject, comprising:a container for containing the substance;a nosepiece extending from the device for placement in proximity to the nose of a subject, with the nosepiece in fluid communication with the container;a valve mechanically connectable to the container, characterized by an active configuration and an inactive configuration; anda trigger mechanism adapted to reversibly reconfigure the valve from the active configuration to the inactive configuration. The mouthpiece is fluidly connectable to by means of a tubule to a fluid reservoir containing a fluid. Drawing liquid from the reservoir into the mouth via the mouthpiece reconfigures the valve from the inactive configuration to the active configuration for a predetermined period of time in response to the pressure gradient generated by the suction applied by the subject to the tubule.
