  • Patent number: 11986375
    Abstract: A deep insert, inflatable hearing protection earplug is provided that is easy for an untrained user to insert correctly, reliably providing high acoustic attenuation and remaining both secure and comfortable for long durations in a human ear. The earplug comprises a soft elastomer shell that forms a sealed volume filled with an inert fluid. The earplug can comprise a slender, flexible stem that is easily insertable into the ear canal when deflated. The proximal end of the earplug can be situated outside the ear canal, within the concha of the ear, and incorporates a bulb with a hemispherical, bistable cap. After inserting the shaft of the earplug into the ear canal, the wearer applies force with a finger to invert the cap, which transitions elastically from a convex to a concave external geometry, displacing a fixed volume of fluid to inflate a sheath that forms the outer covering of the stem, filling and sealing the ear canal.

  • Patent number: 9492068
    Abstract: 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.
