Protection Aid / band aid

Protection aid is a band aid that can provide the wound a safer and sanitary environment.
With the traditional band aid, it usually sticks to the wound at the very beginning (or gradually)and causes the second time injury, making it harder to be healed.
The protection aid functions like a green house to injury. The space inside the protection aid provide a breathable, waterproof, UV protection - a safe and hygienic environment without touching the wound. It’s easy to use and remove, and people now have no need to worry about the wound until it is healed. It creates a perfect environment for healing.
