Abstract
Abstract Hemostatic adhesive bandages are disclosed wherein a very thin coating of a high molecular weight polyethylene oxide is applied to the surface of the perforated plastic film wound release cover of an adhesive bandage, in a manner compatible with commonly used high speed production techniques and equipment, which stop the bleeding faster when applied to minor cuts.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
71 words
An adhesive bandage for use on minor cuts and wounds, which consists of a pressure-sensitive adhesive coated backing having attached thereto an absorbent pad bandage portion covered with a perforated plastic film wound release cover, characterised in that it includes: a very thin coating comprising a polyethylene oxide having a molecular weight of at least 600,000, on said wound release cover, thereby to improve the hemostatic effect of said adhesive bandage.
Claim 2
Dependent Claim
71 words
An adhesive bandage for use on minor cuts and wounds, which consists of a pressure-sensitive adhesive coated backing having attached thereto an absorbent pad bandage portion covered with a perforated plastic film wound release cover, characterised in that it includes: a very thin coating comprising a polyethylene oxide having a molecular weight of at least 600,000, on said wound release cover, thereby to improve the hemostatic effect of said adhesive bandage.
Claim 3
Dependent Claim
18 words
The adhesive bandage of Claim 1, wherein the polyethylene oxide has a molecular weight of at least 4,000,000.
Claim 4
Dependent Claim
40 words
3 . The adhesive bandage of claim 1 or claim 2, wherein the add-on weight of the polyethylene oxide is from 1% - 10% of the weight of the perforated plastic film wound release cover to which it is added.
Claim 5
Dependent Claim
30 words
The adhesive bandage of Claim 3, wherein the add-on weight of the polyethylene oxide is from 2% - 8% of the weight of the perforated plastic film wound release cover.
Claim 6
Dependent Claim
28 words
5 . The adhesive bandage of any one of claims 1 to 4, wherein the wound release cover is made from polyethylene, polypropylene or polyester perforated plastic film.
Claim 7
Dependent Claim
11 words
The adhesive bandage of any of Claims 1-5 in sterile form.
Claim 8
Dependent Claim
66 words
A hemostatic adhesive bandage comprising a backing material, a pressure-sensitive adhesive coating on one side of said backing material, an absorbent pad secured to said side of said backing material, a perforated film wound release cover overlying said absorbent pad, and on the outer surface of said wound release cover a very thin coating comprising a polyethylene oxide having a molecular weight of at least 600,000.
Claim 9
Dependent Claim
66 words
A hemostatic adhesive bandage comprising a backing material, a pressure-sensitive adhesive coating on one side of said backing material, an absorbent pad secured to said side of said backing material, a perforated film wound release cover overlying said absorbent pad, and on the outer surface of said wound release cover a very thin coating comprising a polyethylene oxide having a molecular weight of at least 600,000.
Claim 10
Dependent Claim
90 words
A process for improving the hemostasis effect of an adhesive bandage for use on minor cuts and wounds which consists of a pressure-sensitive adhesive coated backing covered with a perforated plastic film wound release cover comprising carrying out all steps otherwise used to manufacture said adhesive bandage, but additionally dissolving a polyethylene oxide having a molecular weight of at least 600,000 in a solvent, coating the resultant solution on the wound release cover, evaporating off the solvent leaving a very thin coating of polyethylene oxide on the wound release cover.
Claim 11
Dependent Claim
90 words
A process for improving the hemostasis effect of an adhesive bandage for use on minor cuts and wounds which consists of a pressure-sensitive adhesive coated backing covered with a perforated plastic film wound release cover comprising carrying out all steps otherwise used to manufacture said adhesive bandage, but additionally dissolving a polyethylene oxide having a molecular weight of at least 600,000 in a solvent, coating the resultant solution on the wound release cover, evaporating off the solvent leaving a very thin coating of polyethylene oxide on the wound release cover.
Claim 12
Dependent Claim
20 words
The process of Claim 8, wherein the concentration of polyethylene oxide dissolved in the solvent is from 0.5 to 6.5%.
Claim 13
Dependent Claim
13 words
The process of Claim 9, wherein said concentration is from 1.0 to 3.0%.
