Drug delivery device having improved adhesion and attachment system for drug delivery device
First Claim
1. 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 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 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.

Abstract
A system adapted to be disposed between a rigid or semi-rigid device and human skin for reliably attaching the device to the skin for an extended period of time. The system includes a skin-contacting surface for adhering to human skin, and an opposed surface for attachment to a rigid or semi-rigid device. The system is attached along its opposed surface to a portion of the total area of the adjacent surface of the device. When the device is subjected to external stress, the stress is transmitted through the area of attachment and distributed to the unattached area. This minimises stress on the skin and reduces the chance of detachment from the skin.

1. 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 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 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. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. 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.

9. 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 attachment 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;
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; and
wherein a relief cavity is formed between the base and said structure which can accommodate deflection of the skin of the being in use which would otherwise result in higher stress and potential premature detachment thereof. - View Dependent Claims (10, 11, 12)

13. 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.

14. 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. - View Dependent Claims (15, 16)
