Measure the stoma size from the base of the stoma with the measuring guide provided. Trace the stoma outline you have selected onto the release paper on the skin barrier. The small starter hole should be in the center of your tracing. (Gloving may not be necessary; consult with your healthcare professional). Cut the center hole the same size as the stoma. Cut along the tracing with curved, short-blade scissors. Remove the release paper on the skin barrier. Gently place the skin barrier in place around the stoma holding the skin barrier for 30 seconds to ensure a snug fit around the stoma. If you are using a flexible skin barrier (taped border), you can remove the paper on one side of the skin barrier and smooth onto the skin. Repeat with the other side, making sure the tape is smooth and wrinkle-free. If you are using a drainable pouch, prior to applying the pouch it is recommended that you close the InvisiClose clipless tail closure system by folding upward and pressing the interlocking closures together until you feel them lock into place. A "click" indicates a secure closure Make sure the inner surfaces of the pouch are separated and that the pouch contains a small amount of air. Remove the release paper from the ring on the pouch. Fold the top half of the wafer toward yourself so that you can see the application around the stoma and then roll your fingers over the upper portion to secure the pouch. Always look beneath the top of the pouch at the adhesive to ensure the pouch-to-skin barrier adhesion is secure.
