Seal-Tight waterproof wound bandage and cast covers are durable enough to last throughout the life of the cast. This waterproof cast cover gives users more freedom while swimming or taking a shower. It is a professional post-treatment solution to prevent deterioration or water damage of a cast or bandage. Easy to use:1. After removing your cast protector from the box, unfold it completely. 2. Pull Seal-Tight Protector overdressing or PICC line by stretching the opening of the protector over your dressing while pulling up. You will know it’s at the right position on your arm or leg when the seal opening sits comfortably above the top edge of the dressing. Important note: The seal should be tight, after all, it’s keeping water off of your dressing. Never trim with scissors or puncture. It’s ok if the bag appears oversized, as this allows room for large dressings and easy movement.3. Partially submerge the protector into the water while simultaneously holding a portion of the proximal (uppermost) seal away from your skin with one finger. This will allow any excess air to escape easily from the bag. 4. When excess air has escaped, remove your finger so the seal fits snugly against your skin.Always check with your doctor to be sure bathing is appropriate in your situation and enjoy your Seal-Tight cast protector.This cast cover passes the standards of National Health Service recommendations for chronic wounds.
