One step dressing delivery system

Claim 2

A dressing having a delivery system to facilitate application of the dressing onto a human which comprises: (a) a thin flexible backing layer having a suitable adhesive on substantially all of one surface thereof, the backing layer and the adhesive being impermeable to liquids but permeable to water vapor and oxygen, and a pair of ends and a transverse fold such that at least a portion of the non-adhesive coated side of the backing layer is adjacent itself; (b) a protective package enclosing the dressing comprising a pair of layers releasably sealed to each other outside the periphery of the dressing; (c) a release layer between the adhesive of the folded backing layer and the package fixedly attached to the package and split along a line adjacent the fold, the release layer having a substantially greater stiffness and resistance to wrinkling than the dressing; (d) opening means on the package adjacent the fold; and (e) dressing release-retarding means at each end of the dressing, said dressing having a water vapor transmission rate of at least 250 g/m 2 /24 hrs/40° C./80% RH.

Claim 3

A dressing having a delivery system according to claim 1 wherein the backing layer and the adhesive on one surface of the backing layer are transparent.

Claim 4

A dressing having a delivery system according to claim 1 wherein the backing layer is a transparent polyurethane film having a thickness of about 0.5 to 2 mils.

Claim 5

A dressing having a delivery system according to claim 3 wherein the adhesive on the polyurethane film is a layer about 1 mil thick.

Claim 6

A dressing having a delivery system according to claim 1 wherein the adhesive is a pressure sensitive acrylic ester copolymer.

Claim 7

A dressing having a delivery system to facilitate application of the dressing onto a human which comprises: (a) a breathable dressing comprising a substantially rectangular backing layer of a thin flexible transparent polyurethane film having an acrylic copolymer adhesive on substantially all of one surface thereof and having a pair of ends and a transverse fold dividing the dressing into two equal portions such that the uncoated side of the polyurethane film is adjacent itself with ends aligned; (b) a protective package enclosing the dressing comprising a pair of layers of sterilizable paper releasably sealed to each other with a suitable contact adhesive outside the periphery of the dressing; (c) a release layer of silicon release coated paper having a substantially greater stiffness and resistance to wrinkling than the dressing disposed between the adhesive coating of the dressing and the package fixedly attached to the package with a suitable contact adhesive and split along a line adjacent the fold; (d) a pair of opening tabs adjacent the fold integral with the package; and (e) release-retarding means at each end of the dressing in the form of a strip of the dressing parallel with the fold in contact with the dressing layer.

Claim 8

A dressing having a delivery system to facilitate application of the dressing onto a human which comprises: (a) a breathable dressing comprising a substantially rectangular backing layer of a thin flexible transparent polyurethane film having an acrylic copolymer adhesive on substantially all of one surface thereof and having a pair of ends and a transverse fold dividing the dressing into two equal portions such that the uncoated side of the polyurethane film is adjacent itself with ends aligned; (b) a protective package enclosing the dressing comprising a pair of layers of sterilizable paper releasably sealed to each other with a suitable contact adhesive outside the periphery of the dressing; (c) a release layer of silicon release coated paper having a substantially greater stiffness and resistance to wrinkling than the dressing disposed between the adhesive coating of the dressing and the package fixedly attached to the package with a suitable contact adhesive and split along a line adjacent the fold; (d) a pair of opening tabs adjacent the fold integral with the package; and (e) release-retarding means at each end of the dressing in the form of a strip of the dressing parallel with the fold in contact with the dressing layer.
