Patent ID: 8568348

Claim:
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 fluid delivery port axially aligned with the longitudinal axis at the distal end of the earplug device; wherein the earplug device further comprises a fluid drain hole formed in the conformable outer annular convex seal surface at a position that is laterally offset from the longitudinal axis of the earplug device, the fluid drain hole having a lateral width that is smaller than a lateral width of the fluid lumen extending along the longitudinal axis of the earplug device, wherein the fluid drain hole is configured to drain at least a portion of a treatment fluid in a proximal direction away from an inner ear region after said treatment fluid is dispensed distally of the distal fluid delivery port at the distal end of the earplug device; 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 said 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 an overall axial length of the earplug device.
