Fluid medication delivery device

A fluid medication delivery device, comprising:

• a fluid impermeable layer;
• a fluid semi-permeable layer, said semi-permeable layer and said impermeable layer cooperating to define a space therebetween, said space defining a fluid reservoir of said delivery device, said semi-permeable layer and said impermeable layer having a continuous seal therebetween to define a periphery of said fluid reservoir;
• at least one internal wall within the periphery of said fluid reservoir configured so as to form multiple interconnected regions within said fluid reservoir, each said internal wall formed by securing a portion of said fluid impermeable layer located inside said periphery to a portion of said fluid semi-permeable layer located inside said periphery such that said portion of said fluid impermeable layer abuts said portion of said fluid semi-permeable layer;
• and
• 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 connector for a supply of fluid, said delivery device adapted to selectively secure said connector in the radial and axial direction, wherein said valve comprises a one-way valve configured such that, when said connector is secured to said fluid inlet, said one-way valve permits fluid to enter said fluid reservoir and prevents fluid from exiting said fluid reservoir through said fluid inlet;
• wherein a fluid is diffusable across said semi-permeable layer in response to a pressure imparted on said fluid.
