Abstract
A re-closable wound dressing is provided. A base layer is operable to be attached to a skin of a patient. The base layer forms a pre-fabricated aperture through which a wound of the patient is accessible. A cover layer is coupled with the base layer. The cover layer is operable to cover the pre-fabricated aperture, and is permanently adhered to the base layer along at least a portion of the cover layer. The base layer and the cover layer are made of like materials.
Claims21
A re-closable wound dressing comprising:
- a base layer operable to be attached to a skin of a patient, the base layer forming a pre-fabricated aperture through which a wound of the patient is accessible;
- a cover layer having a first adhesive region that is permanently adhered to the base layer to prevent, during normal operation, the cover layer from being separated from the base layer;
- an additional adhesive layer operable to be disposed on the base layer and facing the cover layer and bordering at least a portion of the pre-fabricated aperture;
- the cover layer having a second adhesive region that is configured to be removably coupled with the additional adhesive layer of the base layer;
- wherein the cover layer further includes:
- a first adhesive layer that includes the first adhesive region and the second adhesive region;
- an inner film adhered to the first adhesive layer;
- a second adhesive layer adhered to the inner film opposite the first adhesive layer;
- and
- a top film adhered to the second adhesive layer opposite the inner film,
- wherein the cover layer is configured to overlay the pre-fabricated aperture formed in the base layer;
- wherein the base layer and the cover layer are made of materials with substantially similar flexibility and stretch properties.
