What type of biomedical engineer typically works in medical settings, maintaining diagnostic and therapeutic devices and aids and training others on proper usage? clinical engineer biomedical engineer medical engineer rehabilitation engineer?

I believe the answer is rehabilitation engineer. Rehabilitation engineering is the systemic application of engineering sciences to design, develop, adapt, test, evaluate, apply, and distribute technological solutions to problems confronted by individuals with disabilities. It involves the use of engineering principles to develop technological solutions and devices to assist individuals with disabilities and also to aid the recovery of physical and cognitive functions lost because of disease or injury.
