Abstract
An adhesive composite dressing useful for applying an active ingredient to a treated skin site, as well as methods of manufacture and use of such dressings. In one embodiment, an adhesive composite dressing comprising an anchor member, a target member, and a folding member, where the anchor member comprises a first skin-contact adhesive, the target member comprises an opening adapted to enable skin treatment, the folding member comprises a drug reservoir, and where the folding member is attached to the anchor portion through a hinge defined by a line of attachment that is not contiguous with an edge of the anchor member.
Claims14
An adhesive composite dressing comprising:
- an anchor member comprising a first skin-contact adhesive;
- a target member comprising an opening adapted to enable skin treatment;
- a folding member comprising a drug reservoir and a second skin-contact adhesive, wherein the folding member is attached to the anchor member through a hinge defined by a line of attachment that is not contiguous with an edge of the anchor member;
- and
- an impermeable barrier between the drug reservoir and the second skin-contact adhesive.
A method of applying a drug reservoir to a treated area of skin with a patch comprising an anchor member, a target member, and a folding member, the folding member comprising the drug reservoir and being attached to the anchor portion through a hinge defined by a line of attachment that is not contiguous with an edge of the anchor member, the target member comprising an opening adapted to enable skin treatment, the method comprising:
- attaching the anchor member of the patch to a non-treated area of skin,
- treating the area of skin left exposed by the target opening with a treatment method that increases the permeability of the skin,
- rotating the folding member around the hinge so that at least a portion of the folding member adheres to the skin and so that the drug reservoir contacts the treated area of skin and
- removing the anchor member from the skin while leaving the drug reservoir in contact with the treated area of skin.
