Medtrade is a big event where people who sell things that help people with medical problems to feel better get together to show off their stuff. There are lots of different things to look at, like special chairs and wheelchairs that make it easier for people to get around, machines that can help people breathe better, and things to help people with diabetes check their blood sugar. People who work in hospitals or doctor's offices go to Medtrade to see all the cool new products, and sometimes they even buy them to use with their patients!
