Time to Change / Bandage

Time to Change

Bandage has an inhibitory effect on bleeding and infection, but after some time, if it hasn’t been changed, bacteria will breed, which do harm for the wound healing. “Time to change” can remind people to change the bandage by showing red dots on the surface of it.
