A transparent, semi-permeable (i.e., impermeable to fluids, permeable to vapours and gases) covering applied to wounded or diseased tissue intended to provide protection (e.g., from dirt, water) and/or promote healing. It is a thin, clear film made of synthetic polymer material that is covered on one side with a pressure-sensitive adhesive. It may be applied directly to tissue or used in combination with other dressings (e.g., gauze) to protect postsurgical incisions and minor wounds (e.g., cuts, scrapes, burns, skin tears, blisters). It may also be used to secure to skin other devices such as vascular catheters, infusion ports, or tubing. This is a single-use device.
