10 Medical Uses For Duct Tape
8. Taping Joints and Bones

Sometimes it is necessary to think fast, finding relief for sore joints or a sprained finger. In these instances, a splint can protect the affected area, reducing the risk of further damage. For those who enjoy hiking, duct tape is a great addition to the kit of safety supplies, as you never know when you may need a brace or splint.
If a broken bone needs treatment, two sticks and some duct tape will do the trick until there is access to proper care. If gauze is available, even better! In the case of a broken arm, for instance, it is necessary to minimize movement. Place a stick on both sides of the arm, wrap with gauze (if available), then use the duct tape to secure.
7. Standard Bandage

Far too often a nick will happen in the kitchen or while shaving, only to discover no bandages are available. If there is need for an emergency bandage, duct tape is the perfect water-resistant solution. As long as there is gauze available, the wound can be covered with the soft gauze material and wrapped with duct tape.
If gauze is not available, a small piece of clean tissue or cloth will also do the trick. A small strip of duct tape is all that is needed, don't overdo it. Make sure the area is cleaned first, then change the 'duct tape bandage' frequently. Once the bleeding stops, ensure the wound is exposed to oxygen between changes.
