Adhesive structure for medical device
First Claim
1. A system for anchoring a location on a surface of a medical infusion device to a skin of a user, the system comprising:
- an adhesive substrate for adhering to the skin of the user;
a stiffener directly covering a portion of the adhesive substrate; and
an interface directly covering a portion of the stiffener, such that the stiffener is interposed between the interface and the adhesive substrate and is arranged below a horizontal plane of the interface and above a horizontal plane of the adhesive substrate, the interface attaching a portion of said adhesive substrate to the surface of the device,wherein said adhesive substrate is a separate and distinct layer from said stiffener and said interface;
wherein said adhesive substrate includes a skirt extending beyond said interface, said skirt being flexibly attached to said interface; and
wherein the stiffener directly covers and stiffens a portion of said skirt, said stiffener being less flexible than said substrate.

Abstract
A variable flexibility adhesive system may adhere a surface of a medical infusion device to the skin of a user. The system may be configured to hold a location on the surface stationary with respect to a site on the user'"'"'s skin. The system may include an adhesive substrate for adhering to the user and an interface where the substrate is held to the surface of the device. The interface may totally and/or partially surround the stationary location. A skirt of the substrate may totally and/or partially surround the interface. Parts of the skirt may be stiffened. Optional features may include tabs for activation of the adhesive and/or a location for peeling the infuser away from the skin. Additionally or alternatively, the interface may have variable flexibility. Additionally or alternatively, the stiffener may include a plastic layer.

22. A system for anchoring a location on a surface of a medical infusion device to a skin of a user the system comprising:
-
a flexible adhesive substrate for adhering to the skin of the user; an interface attaching said adhesive substrate to the surface of the device and wherein said interface includes at least one relatively flexible region and at least one less flexible region; a stiffener directly covering a portion of the adhesive substrate, wherein the interface covers a portion of the stiffener, such that a portion of the stiffener is interposed between the interface and the adhesive substrate and is arranged below a horizontal plane of the interface and above a horizontal plane of the adhesive substrate; an adhesive cover; and a tab for peeling said adhesive cover from said adhesive substrate, wherein said adhesive substrate is a separate and distinct layer from said stiffener and said interface, wherein the stiffener is affixed to an unattached portion of said adhesive substrate, and wherein said stiffener supports said adhesive substrate adjacent to said tab, supplying an opposing force when peeling said adhesive cover away from said adhesive substrate. - View Dependent Claims (23, 24)
