Drug delivery device having improved adhesion and attachment system for drug delivery device

An attachment system for reliably attaching a device to the skin of a being, and wherein the device includes a rigid or semi-rigid base having a first plurality of attachment members located thereon and a periphery, said system comprising:

• a structure having a skin-attaching surface and a base-attaching surface, said skin-attaching surface comprising an adhesive for adhering to the skin of the being, said skin-attaching surface having a periphery larger than the periphery of said rigid or semi-rigid base;
• and
• said base-attaching surface being located opposite to said skin-attaching surface and comprising a central region, a peripheral edge and a second plurality of attachment members and wherein said first and second plurality of attachment members cooperate to couple said rigid or semi-rigid base to said base-attaching surface but wherein said central region and said peripheral edge remain uncoupled to said rigid or semi-rigid base, thereby minimizing stress omnidirectionally on the skin of the being and reducing the chance of premature detachment from the skin of the being.

An attachment system for reliably attaching a device to the skin of a being, and wherein the device includes a rigid or semi-rigid base having a periphery, said system comprising:

• a generally planar member having a skin-attaching surface and a base-attaching surface, said skin-attaching surface comprising an adhesive for adhering to the skin of the being, said skin-attaching surface having a periphery larger than the periphery of said rigid or semi-rigid base;
• and
• said base-attaching surface having a central region and a peripheral edge and wherein said base-attaching surface is coupled to said rigid or semi-rigid base at discrete adhesive locations but is uncoupled to said rigid or semi-rigid base at its central region and at its peripheral edge, thereby minimizing stress omnidirectionally on the skin of the being and reducing the chance of premature detachment from the skin of the being.

An attachment system for reliably attaching a device to the skin of a being, and wherein the device includes a rigid or semi-rigid base having a periphery, said system comprising:

• a member having viscoelastic properties approaching that of the skin of the being, a skin-attaching surface and a base-attaching surface, said skin-attaching surface comprising an adhesive for adhering to the skin of the being, said skin-attaching surface having a periphery larger than the periphery of said rigid or semi-rigid base;
• and
• said base-attaching surface having a central region and a peripheral edge and wherein said base-attaching surface is coupled to said rigid or semi-rigid base at discrete adhesive locations but is uncoupled to said rigid or semi-rigid base at its central region and at its peripheral edge, thereby minimizing stress omnidirectionally on the skin of the being and reducing the chance of premature detachment from the skin of the being.
