摘要:Button batteries are used in toys, cameras, remote controls, and many other products, and can be found in almost every home. Nowadays, button batteries have increased in size and voltage, which puts children at great risk of serious injury. In the interest of children's safety, parents and caregivers are educated to keep button batteries-controlled devices out of reach of children, but this practice does not effectively prevent accidental ingestion. In this study, we placed a button battery between two slices of ham to measure the pH values, current and voltage to reveal the danger of button battery ingestion. And we examine the effectiveness of a button battery burn injury demonstration to raise awareness of the injury risk among parents and caregivers.
