Medica Colostomy Skin Barrier is a single ostomy skin-barrier accessory designed to create a protective adhesive interface around the stoma and support attachment of a compatible colostomy pouch. Components and specifications: One adhesive ostomy skin barrier or wafer with a skin-contact surface. Directions: Clean the stoma and surrounding skin with water and dry completely. Measure the stoma, prepare the opening to fit closely without constriction, remove the protective backing and press the barrier smoothly from the stoma outward. Attach only a compatible pouch. Important precautions: Use only with a compatible pouch system. Seek stoma-care advice for persistent leakage, bleeding, colour change or damaged skin. Single use only.
