Learning to pop blisters in epidermolysis bullosa with a simple model

Epidermolysis bullosa (EB) is a genetic disorder with skin fragility resulting in easy blistering of skin and mucous membranes. A plane of cleavage exists even where there is no visible blister, so new blisters should be drained as soon as possible to prevent their expansion. Although, learning how to drain blisters safely and painlessly without introducing infection is essential, it can be a major challenge, especially for new parents and children. To avoid demonstrating the technique directly on patient's skin, we have devised a simple teaching aid simulating a hand and forearm with multiple blisters, created with readily available materials. In our experience, we have found this low-cost model to be extremely useful to teach patients, families, and professional groups, how to drain EB blisters and it provides an effective, low-cost, painless substitute for real-life blisters, empowering parents and engaging children.
