Non-stretching wound dressing
First Claim
1. A non-stretching wound dressing comprising:
- a one-piece carrier sheet;
a film sheet having a first adhesive layer on one side thereof adjacent said carrier sheet;
a cover sheet having a second adhesive layer adjacent said film sheet, said second adhesive layer adhering said cover sheet to said film sheet and covering essentially all of one side of said cover sheet;
a first gripping tab on one end of said cover sheet for separating and removing said carrier sheet from said film sheet and from said wound dressing with said cover sheet remaining affixed to said film sheet, said adhesion between said cover sheet and said film sheet being selected such that pulling said first tab releases said film sheet from said carrier sheet with said cover sheet remaining affixed to said film sheet; and
a second gripping tab on an opposite end of said cover sheet from said first gripping tab for releasing said cover sheet from said film sheet, said adhesion between said cover sheet and said film sheet being further selected such that, after removal of said carrier sheet from said wound dressing and application of the adhesive side of said film sheet to a patient, pulling on said second tab releases said cover sheet from said film sheet with said film sheet remaining in place on said patient.

Abstract
A non-stretchable wound dressing has a flexible, non-stretching cover sheet having adhesive on one side thereof, and having two spaced strip-form gripping tabs at opposite ends thereof. The cover sheet covers a urethane wound dressing with the adhesive of the cover sheet being in contact with the urethane, and the urethane having an adhesive layer on an opposite side thereof. For storage and prior to application to a patient, the adhesive of the urethane wound dressing is in contact with a releasable surface of a carrier, such as cardboard. For application to a patient, one of the cover sheet gripping tabs is pulled so as to release the cover sheet and wound dressing from the carrier, the cover sheet preventing stretching of the wound dressing. The combination is then applied to a patient, with the adhesive of the wound dressing in contact therewith, again the cover sheet preventing stretching of the wound dressing. The other gripping tab of the cover sheet is then pulled to separate the cover sheet from the wound dressing, leaving the wound dressing on the patient with no stretching thereof. An optional third gripping tab and minor cover sheet may be located beneath the second gripping tab.
