Abstract
Abstract A delivery system for adhesively affixed copolymer medical coverings such as adhesive bandages, surgical drapes, medical dressings and the like includes a film sheet disposed on and supported by a film sheet carrier. A transfer adhesive is disposed on all but one edge of a transfer sheet which is then positioned on the film sheet surface opposite the film sheet carrier with a release sheet remaining in place until affixation to a subject to cover and protect the transfer adhesive. The one edge of the transfer sheet without adhesive provides a grasping edge whereby the release sheet can be easily removed prior to affixation to the subject. A pull strip is affixed to one edge of the film sheet to facilitate removal of the film sheet from the subject after use. A carrier removal tab is affixed to the back of the film sheet carrier to facilitate its separation from the film sheet after affixation of the film sheet to the subject.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
239 words
A delivery system for self-adhering copolymer medical coverings for covering parts of biological subjects comprising: a film sheet for covering a selected part of the biological subject, the film sheet having a subject facing surface and a back surface; a film sheet carrier, the film sheet releasably adhering to the film sheet carrier along the back surface of the film sheet, the film sheet carrier being inelastic relative to the film sheet but bendable to conform generally to the contours of the part of the biological subject for supporting the film sheet until after the film sheet is affixed to cover the selected part of the biological subject, the film sheet carrier thereafter being removed; a release sheet; a transfer adhesive disposed for covering at least a portion of the release sheet, the release sheet and transfer adhesive positioned adjacent the subject facing surface of the film sheet whereby the transfer adhesive adheres to at least a portion of the subject facing surface so that the film sheet is sandwiched between the release sheet and the film sheet prior to application to the selected part of the biological subject and whereby the transfer adhesive transfers to the film sheet upon removal of the release sheet in preparation for affixation of the film sheet to the selected part of the biological subject, the film sheet being adhesively held to the selected part of the biological subject by the transfer adhesive.
Claim 2
Dependent Claim
239 words
A delivery system for self-adhering copolymer medical coverings for covering parts of biological subjects comprising: a film sheet for covering a selected part of the biological subject, the film sheet having a subject facing surface and a back surface; a film sheet carrier, the film sheet releasably adhering to the film sheet carrier along the back surface of the film sheet, the film sheet carrier being inelastic relative to the film sheet but bendable to conform generally to the contours of the part of the biological subject for supporting the film sheet until after the film sheet is affixed to cover the selected part of the biological subject, the film sheet carrier thereafter being removed; a release sheet; a transfer adhesive disposed for covering at least a portion of the release sheet, the release sheet and transfer adhesive positioned adjacent the subject facing surface of the film sheet whereby the transfer adhesive adheres to at least a portion of the subject facing surface so that the film sheet is sandwiched between the release sheet and the film sheet prior to application to the selected part of the biological subject and whereby the transfer adhesive transfers to the film sheet upon removal of the release sheet in preparation for affixation of the film sheet to the selected part of the biological subject, the film sheet being adhesively held to the selected part of the biological subject by the transfer adhesive.
Claim 3
Dependent Claim
30 words
The delivery system of Claim 1 further comprising: a pull strip adhesively attached along at least a section of one edge of the subject facing surface of the film sheet.
Claim 4
Dependent Claim
57 words
The delivery system of Claim 2 wherein at least a section of the release sheet is transfer-adhesive free, the transfer-adhesive free section being positioned over the pull strip whereby at least a portion of the pull strip is free of transfer adhesive to facilitate grasping and removal of the film sheet from the biological subject after use.
Claim 5
Dependent Claim
56 words
The delivery system of Claim 1 wherein at least a section of the release sheet is transfer-adhesive free, the delivery system comprising: a gauze affixed to a section of the film sheet; an adhesive for affixing the gauze to the-section of the film sheet, the adhesive-free section of the release sheet being positioned over the gauze.
Claim 6
Dependent Claim
78 words
The delivery system of Claims 1, 2, 3 or 4, further comprising: a carrier removal tab attached to the film sheet carrier for being grasped and pulled to thereby pull the film sheet carrier from the back surface of the film sheet after placement of the film sheet on the selected part of the biological subject, the carrier removal tab being positioned so that the film sheet carrier is between the film sheet and the carrier removal tab.
Claim 7
Dependent Claim
20 words
The delivery system of Claim 5 wherein the carrier removal tab is permanently adhesively attached to the film sheet carrier.
Claim 8
Dependent Claim
25 words
The delivery system of Claim 5 wherein the carrier removal tab has a thickness at least five times the thickness of the film sheet carrier.
Claim 9
Dependent Claim
22 words
The delivery system of Claims 1, 2, 3 or 4 wherein the film sheet has a thickness less than about one-half mil.
Claim 10
Dependent Claim
12 words
The delivery system of Claim 1 wherein the film sheet is polyurethane.
Claim 11
Dependent Claim
13 words
The delivery system of Claim 1 wherein the film sheet carrier is Mylar.
Claim 12
Dependent Claim
33 words
The delivery system of Claim 1 wherein the film sheet is stretchable copolymer for conforming to variations in the contours of the selected part of the biological subject as the biological subject moves.
Claim 13
Dependent Claim
71 words
The delivery system of Claim 1 wherein at least a section of the release sheet is free of transfer adhesive and the transfer adhesive and release sheet are joined to the subject facing surface of the film sheet so that an edge region of the film sheet is free of transfer adhesive when the release sheet is removed and the film sheet applied to the selected part of the biological subject.
