Nasal aerosol delivery system

摘要

A nasal delivery device can include a nasal prong and an activation member. The nasal prong can comprises an opening at a top and bottom portion of the prong to allow for the passage of an aerosolized treatment agent through the nasal prong. The activation member can be positioned on the nasal delivery device at a location that is spaced apart from the subject's oral cavity when the nasal prong is received into the nostril of the subject. The activation member can be configured to detect a desired exhalation state of the subject and upon detection of the desired exhalation state, the activation member activates the delivery of the aerosolized treatment agent.

主权项

1. A nasal delivery device for delivering a treatment agent in an aerosolized form to a subject, the device comprising:
a nasal prong comprising an opening at a top and bottom portion of the prong to allow for the passage of the aerosolized treatment agent through the nasal prong, at least a portion of the nasal prong being configured to be received into a nostril of the subject; a nebulizing device having a motion transmitting member coupled to the nasal prong; and a remote activation member configured to detect an oral exhalation of the subject without coming into direct contact with the subject and generate an activation signal in response thereto, the remote activation member being positioned on the nasal delivery device at a location that is spaced apart from an oral cavity of the subject when the nasal prong is received into the nostril of the subject, wherein the nebulizing device has an aerosolizing mode and a non-aerosolizing mode, the remote activation member generating the activation signal to cause the nebulizing device to switch from the non-aerosolizing mode to the aerosolizing mode to deliver the aerosolized treatment agent through the nasal prong.
