The Easy Aid is the one-handed adhesive bandage you have been waiting for. Designed by Pei Chih-Deng, this product can be applied quickly with only one hand.
The key is a plastic gasket that can be removed using one's thumb and middle finger. Unlike other bandaids, the gasket allows you to pinpoint the post-puncture location and place the bandage without difficulty. The cover can be taken off with one hand as a result.
The Easy Aid was designed with self-injecting patients -- like people who have diabetes or hemophiliacs -- in mind. Even if you aren't regularly applying bandaids, this item would also come in handy if you are trying to help a child or if things got particularly messy.
