Abstract

Abstract A delivery system for a wound dressing comprising, an elastomeric film having a front surface, a back surface, an adhesive on the front surface, a first end margin, and a second opposed end margin, with the film having a pressure-sensitive adhesive on the front surface. The system has a release sheet releasably attached to and covering the adhesive on the film. The system has a tab member secured to the back surface of the film adjacent to the first end margin. The system also has a support sheet releasably attached to the back surface of the film, with the support sheet having a first end margin located adjacent to the tab member and being free of attachment to the tab member, and a second end margin located adjacent to the second end margin of the film.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 283 words
A delivery system for applying a wound dressing comprising: an elastomeric film wound dressing characterized by not being self-supporting and as having a tendency towards inadvertent wrinkling when attempting to apply the dressing to the wound, the film having a front surface, a back surface, a first end margin defining a first end edge and a second end margin defining a second end edge; a pressure-sensitive adhesive layer on the front surface of the film; a release sheet releasably attached to and covering the adhesive layer on the film; a tab member secured to the second end margin of the film on the back surface of the film, the tab member having an end edge generally aligned with the second end edge of the film; a support sheet having a front surface, a back surface, a first end margin defining a first end edge, a second end margin defining a second end edge, the support sheet having its front surface releasably secured to the back surface of the film, the second end edge of the support sheet being located over the tab member with the support sheet being free of attachment from the tab member; and first and second indicating strips secured to the back surface of the support sheet in the first and second margins of the support sheet with the first indicating strip including a first means indicating a first manipulation for separating the film from the release sheet for applying the dressing to the wound without wrinkling and the second indicating strip including a second means signifying a second manipulation to peel the support sheet from the back of the film after the dressing has been applied to the wound.
Claim 2
Dependent Claim 283 words
A delivery system for applying a wound dressing comprising: an elastomeric film wound dressing characterized by not being self-supporting and as having a tendency towards inadvertent wrinkling when attempting to apply the dressing to the wound, the film having a front surface, a back surface, a first end margin defining a first end edge and a second end margin defining a second end edge; a pressure-sensitive adhesive layer on the front surface of the film; a release sheet releasably attached to and covering the adhesive layer on the film; a tab member secured to the second end margin of the film on the back surface of the film, the tab member having an end edge generally aligned with the second end edge of the film; a support sheet having a front surface, a back surface, a first end margin defining a first end edge, a second end margin defining a second end edge, the support sheet having its front surface releasably secured to the back surface of the film, the second end edge of the support sheet being located over the tab member with the support sheet being free of attachment from the tab member; and first and second indicating strips secured to the back surface of the support sheet in the first and second margins of the support sheet with the first indicating strip including a first means indicating a first manipulation for separating the film from the release sheet for applying the dressing to the wound without wrinkling and the second indicating strip including a second means signifying a second manipulation to peel the support sheet from the back of the film after the dressing has been applied to the wound.
Claim 3
Dependent Claim 26 words
A delivery system as defined in claim 1 wherein the first end margin of the support sheet extends past the first end margin of the film.
Claim 4
Dependent Claim 18 words
