Patent ID: 8241269

Claim:
A fluid medication delivery device, comprising: a first fluid impermeable layer; a diffusion layer, said diffusion layer and said first fluid impermeable layer cooperating to define a space therebetween, said space defining a fluid reservoir of said delivery device, said diffusion layer and said first fluid impermeable layer having a continuous seal therebetween to define a periphery of said fluid reservoir; a second fluid impermeable layer between said first fluid impermeable layer and said diffusion layer comprising a plurality of openings collectively defining a diffusion area of said device, wherein a lowermost surface of the first fluid impermeable layer and an uppermost surface of the second fluid impermeable layer define a generally unobstructed, hollow cavity between the respective surfaces; a fluid inlet communicating with said fluid reservoir, said fluid inlet comprising a valve configured to permit fluid entry into said fluid reservoir, said fluid inlet adapted to permit said delivery device to be selectively connectable to a supply of fluid; wherein a fluid is diffusable across said diffusion layer in response to a pressure imparted on said fluid.
