Abstract:
1. An ear medication delivery device, comprising: an earplug device including a distal end, a proximal end, a fluid lumen extending along a longitudinal axis of the earplug device between the proximal end and the distal end, and a conformable outer annular convex seal surface positioned radially outward from the fluid lumen, wherein at least a portion of the conformable outer annular convex seal surface sealingly engages with an ear canal when the earplug device is inserted into the ear canal; wherein the fluid lumen extends from a tube attachment hub at the proximal end of the earplug device to a distal-most port aligned with the longitudinal axis at the distal end of the earplug device, the distal-most port being configured to dispense a treatment fluid to the ear canal when said portion of the conformable outer annular convex seal surface sealingly engages with the ear canal; wherein the earplug device further comprises an adjustable seal structure positioned along the fluid lumen, wherein the adjustable seal structure is configured to adjust from a closed position to an opened position in response to fluid pressure within the fluid lumen; wherein the earplug device further comprises a plurality of offset holes defined in said conformable outer annular convex seal surface at locations that are offset from the distal-most port located at the distal end of the earplug device, wherein the distal-most port and the plurality of offset holes are configured to be in fluid communication with the ear canal when said portion of the conformable outer annular convex seal surface sealingly engages with the ear canal; and a flexible fluid delivery tube connectable with the tube attachment hub at the proximal end of the earplug device, wherein the flexible fluid delivery tube is configured to provide a fluid delivery path for the treatment fluid between a fluid supply reservoir and the lumen of the earplug device, the flexible fluid delivery tube having a proximal attachment mechanism for connection with the fluid supply reservoir, and the flexible fluid delivery tube having an overall axial length that is greater than a maximum axial length of the earplug device.
