Wound dressing assembly
A wound dressing assembly includes a wound cover and a carrier. The wound cover has a length and width substantially greater than a height (or thickness), a first major surface, and a second major surface, opposite the first. The first major surface has disposed thereon a wound cover pressure sensitive adhesive comprising a colloidal absorbent, and it is arranged and configured to adhere to mammalian skin during use. The carrier has a length and width substantially greater than a height (or thickness), a first major surface, and a second major surface, opposite the first. The first major surface of the carrier is disposed in facing relation and is removably attached to the second major surface of the wound cover, and it has disposed thereon at least one pressure sensitive adhesive. After application of the wound cover to skin for use, the carrier is removable from the wound cover to leave the wound cover adhered to the skin.
1. A wound dressing assembly comprising:
a. a wound cover having:
i. a length and width substantially greater than a height;
ii. a first major surface having disposed thereon a wound cover pressure sensitive adhesive comprising a colloidal absorbent and being arranged and configured to adhere to mammalian skin during use; and
iii. a second major surface, opposite the first major surface wherein the second major surface of the wound cover is substantially impervious to bodily fluids; and
b. a carrier having:
i. a length and width substantially greater than a height;
ii. a first major surface having a plurality of zones, a first zone superposed and removably attached to the second major surface of the wound cover through a releasable element, the first zone of the first major surface of the carrier having disposed thereon at least one pressure sensitive adhesive, and a second zone, at least partially surrounding and extending beyond the first zone and having disposed thereon a second zone pressure sensitive adhesive; and
iii. a second major surface, opposite the first major surface of the carrier;
wherein, the releasable element has a first major surface adhered to the first major surface of the carrier and a second major surface opposite thereof having a first zone pressure sensitive adhesive disposed thereon and wherein the first zone pressure sensitive adhesive has an adhesion to the wound cover that is less than that of the wound cover pressure sensitive adhesive to mammalian skin, whereby the carrier is capable of removal from the wound cover and mammalian skin while the wound cover remains adhered to mammalian skin during use, whereby, after application of the wound cover to skin for use, the carrier is removable from the wound cover to leave the wound cover adhered to the skin.
2. The wound dressing assembly of claim 1 wherein the second zone has a second zone pressure sensitive adhesive disposed thereon for adhesion to the mammalian skin.
3. The wound dressing assembly of claim 1 wherein the carrier has disposed thereon a carrier pressure sensitive adhesive and the second major surface of the wound cover comprises a release agent to enhance the separation of the carrier pressure sensitive adhesive therefrom.
4. The wound dressing assembly of claim 1 wherein the carrier is substantially transparent.
5. The wound dressing assembly of claim 1 wherein the carrier is substantially translucent.
6. The wound dressing assembly of claim 1 wherein the carrier is substantially opaque.
7. The wound dressing assembly of claim 6 wherein the second major surface of the wound cover is decorated.
8. The wound dressing assembly of claim 1 wherein the wound cover is substantially transparent.
9. The wound dressing assembly of claim 1 wherein the wound cover is substantially translucent.
10. The wound dressing assembly of claim 1 wherein the wound cover is substantially opaque.
11. The wound dressing assembly of claim 1 wherein the second major surface of the wound cover is decorated.
12. A method of applying a wound dressing to mammalian skin comprising the steps of:
a. applying to the mammalian skin the wound dressing assembly of claim 1 ;
and
b. removing the carrier from the wound cover, leaving the wound cover adhered to the mammalian skin.
13. The method of claim 12 , wherein the carrier is removed from the wound cover after a period of greater than about 1 hour.
14. The method of claim 12 wherein the carrier is removed from the wound cover after a period of greater than about 6 hours.
