What do medical device nurses in medical device companies do?

I work in a medical device company. I don't know what kind of medical equipment you are talking about. If it is a free experience medical device company in the market, the employees generally recruited are lecturers, that is, they will explain the principles and uses of medical devices, explain some medical knowledge, and operate devices for customers and patients who come to experience. This is what I know. I don't know if it's the position you said!
