Claim Text:
1. A method of using an ear medication delivery device, comprising: inserting an earplug device into an ear canal, wherein the earplug device includes 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 the ear canal; and delivering a treatment fluid through a flexible fluid delivery tube connected to a tube attachment hub at the proximal end of the earplug device, through the fluid lumen of the earplug device, and to a distal fluid delivery port axially aligned with the longitudinal axis at the distal end of the earplug device, wherein the flexible fluid delivery tube provides a fluid delivery path for said treatment fluid between a fluid supply reservoir and the fluid 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; wherein the earplug device further comprises a fluid drain hole that is configured to drain at least a portion of said 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, the fluid drain hole being 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.
