Device for recording and transferring a contour
First Claim
1. A device for transferring tissue contours of a wound or opening onto an adhesive wafer of a wound appliance, the device comprising:
- a transparent polymer sheet having a first non-adhesive surface and a second surface opposite the non-adhesive surface;
said second surface opposite the first non-adhesive surface including a central portion and an edge portion surrounding the central portion, the edge portion including an adhesive, said central portion being configured to receive a drawn image of a tissue contour;
said first non-adhesive surface of the transparent polymer sheet being adapted to non-adhesively contact tissue of the patient when the device is in use and the image is being drawn on the central portion, said second surface with said adhesive on the edge portion facing away from the patient when the image is drawn;
said adhesive of the second surface being attachable to an adhesive wafer of the wound appliance to directly impart the drawn image thereto while said second surface adhesive does not contact the patient; and
the adhesive having a first part that is covered by a first removable release liner and a second part that is covered by a second removable release liner, the second release liner being larger than the first release liner, the first release liner being removed first to enable the first part of the adhesive to be secured to a wafer when the device is properly aligned, the second release liner being removed thereafter to enable the second part of the adhesive to be secured to the wafer.

Abstract
A device for recording and transferring the contours of a wound or opening in tissue of a human being to an adhesive wafer of a wound appliance is provided. The device includes a transparent polymer sheet having a first and a second surface, the first surface being non-adhesive and facing the wound or opening and the second surface having a central portion and an edge portion, with the edge portion being provided with an adhesive layer. The device is placed over the wound or opening and the contours are traced on the central portion of the device. The adhesive layer on the second surface is then adhered to the wafer so that the drawn image contacts the wafer and is directly imparted to the wafer.

11. A device for transferring tissue contours onto an adhesive wafer of a wound appliance, the device comprising:
-
a transparent polymer sheet having a first non-adhesive surface and a second surface opposite the non-adhesive surface; said second surface opposite the non-adhesive surface including a central portion and an edge portion surrounding the central portion, the central portion being without adhesive and the edge portion including an adhesive; a transparent protection layer that is attachable to the non-adhesive surface of the transparent polymer sheet without using an adhesive, the transparent protection layer provided to be placed between the tissue of a patient and the non-adhesive surface of the transparent polymer sheet when drawing an image of a tissue contour onto the central portion of the second surface; and said adhesive of the second surface being attached to the wound appliance so that the central portion of the second surface with the drawn image of the tissue contour contacts the adhesive wafer of the wound appliance and is directly imparted to the adhesive wafer. - View Dependent Claims (12, 13, 14)

15. A method for transferring tissue contours of a wound or opening of a patient onto an adhesive wafer of a wound appliance, the method comprising:
-
providing a device including a transparent polymer sheet having a first non-adhesive, skin-contacting surface and a second adhesive surface opposite the non-adhesive surface, said second adhesive surface including a central portion and an edge portion surrounding the central portion, said second adhesive surface being covered by a non-adhesive transparent layer having a first portion and a second portion separable from one another, the first portion covering the edge portion and the second portion covering the central portion; placing the device over the wound or opening with the first non-adhesive side facing the patient and drawing an image of a tissue contour onto the central portion of the second surface; removing the first portion of the non-adhesive transparent layer to expose the adhesive edge portion; attaching the adhesive edge portion of the second surface to the adhesive wafer of the wound appliance so that the central portion of the second surface with the drawn image of the tissue contour contacts the adhesive wafer of the wound appliance and the drawn image is directly imparted to the adhesive wafer, said adhesive layer not coming into contact with patient tissue; and cutting an opening in the wafer and device that follows the drawn image. - View Dependent Claims (16, 17, 18)
