Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
137 words
A dressing adapted for application to a mammalian body having a wound or lesion, the said dressing comprising:
(a) a dressing substrate adapted for application to the said body; (b) a single metallic electrode; and (c) collagen and/or an ionizable or polar medicament in electrically co-operative relationship with the electrode: the face of the said electrode remote from the said substrate being arranged such that in use at least part thereof directly contacts the body and the said dressing being capable in use of forming a galvanic couple between the said single electrode and the body when the dressing is applied over the wound or lesion and producing, without use of an external power source, a local current effective for iontophoresis whereby the collagen or medicament is caused to contact or migrate within the wound or lesion.
Claim 2
Dependent Claim
137 words
A dressing adapted for application to a mammalian body having a wound or lesion, the said dressing comprising:
(a) a dressing substrate adapted for application to the said body; (b) a single metallic electrode; and (c) collagen and/or an ionizable or polar medicament in electrically co-operative relationship with the electrode: the face of the said electrode remote from the said substrate being arranged such that in use at least part thereof directly contacts the body and the said dressing being capable in use of forming a galvanic couple between the said single electrode and the body when the dressing is applied over the wound or lesion and producing, without use of an external power source, a local current effective for iontophoresis whereby the collagen or medicament is caused to contact or migrate within the wound or lesion.
Claim 3
Dependent Claim
12 words
A dressing as claimed in claim 1 wherein the electrode is aluminum.
Claim 4
Dependent Claim
13 words
A dressing as claimed in claim 2 wherein the electrode is aluminum foil.
Claim 5
Dependent Claim
38 words
A dressing as claimed in any one of the preceding claims wherein an ionizable polar medicament is present and is absorbed within a carrier comprising sterile paper, sterile cloth or hydrogel polymer and being adhered to the dressing.
Claim 6
Dependent Claim
25 words
A dressing as claimed in any one of the preceding claims wherein the medicament is a proteinaceous medicament, comprising an undenatured or a denatured protein.
Claim 7
Dependent Claim
20 words
A dressing as claimed in claim 5 wherein the proteinaceous medicament comprises a denatured protein further including a biocompatible metal.
Claim 8
Dependent Claim
13 words
A dressing as claimed in claim 6 wherein the biocompatible metal is silver.
Claim 9
Dependent Claim
18 words
A dressing as claimed in any one of the preceding claims wherein the medicament is mild silver protein.
Claim 10
Dependent Claim
25 words
A dressing as claimed in claim 8 wherein the single electrode is aluminum foil, the said dressing additionally including a second electrode of aluminum foil.
Claim 11
Dependent Claim
84 words
A dressing as claimed in any one of the preceding claims wherein the substrate comprises a medial portion bounded by terminal portions, the electrode being borne upon the substrate within the said medial portion and supporting a discrete quantity of ionizable or polar medicament within its peripheral dimensions, the electrode presenting sufficient surface area for direct contact with the body to establish an iontophoretically-effective electric current between the medicament and the body to cause migration of the medicament into the wound or lesion thereon.
Claim 12
Dependent Claim
60 words
A dressing as claimed in any one of claims 1 to 9 wherein the substrate comprises a medial portion bounded by terminal portions, ionizable or polar medicament being borne upon the substrate within the medial portion, the electrode being borne on at least one of the terminal portions and partially overlapping the medial portion in electrically-cooperative relationship with the medicament.
Claim 13
Dependent Claim
36 words
A dressing as claimed in any one of the preceding claims wherein the medicament is absorbed within a carrier selected from sterile paper, sterile cloth and hydrogel polymers, the said carrier being adhered to the dressing.
Claim 14
Dependent Claim
15 words
A dressing as claimed in claim I further including an electrochemicallyeffective quantity of an electrolyte.
Claim 15
Dependent Claim
19 words
A dressing as claimed in claim 13 wherein the electrolyte is sodium chloride, potassium chloride or a mixture thereof.
Claim 16
Dependent Claim
47 words
A dressing as claimed in any one of claims 1 to 3, 13 and 14 including a filmforming quantity of collagen fibrils so as to obtain in use an adherent skin-like protective membrane of the collagen fibrils electrochemically-linked to exposed collagen fibrils of the wound or lesion.
Claim 17
Dependent Claim
28 words
A dressing as claimed in claim 15 wherein the collagen fibrils are present in the form of a paste dispersion supported by the substrate and containing an electrolyte.
Claim 18
Dependent Claim
16 words
A dressing as claimed in claim 16 wherein the collagen dispersion is coated on the substrate.
Claim 19
Dependent Claim
16 words
A dressing as claimed in claim 16 wherein the collagen dispersion is impregnated in the substrate.
Claim 20
Dependent Claim
18 words
A dressing as claimed in any one of claims 16 to 18 wherein the collagen dispersion is dried.
Claim 21
Dependent Claim
59 words
A dressing as claimed in claim 15 wherein the metallic electrode is in the form of a metallic film upon which the collagen fibrils are borne in electrically cooperative relationship such that, in use, upon introduction of fluid to the dressing, a galvanic current is generated whereby the collagen fibrils electrochemically link to form the adherent, skin-like protective membrane.
Claim 22
Dependent Claim
17 words
A dressing as claimed in claim 20 further including mild silver protein mixed with the collagen fibrils.
Claim 23
Dependent Claim
15 words
A dressing as claimed in claim 20 wherein the metallic electrode is mild silver protein.
Claim 24
Dependent Claim
11 words
A dressing as claimed in claim 1 substantially as herein described.
Claim 25
Dependent Claim
16 words
A dressing as claimed in claim 1 substantially as herein described with reference to the drawings.
