The goal of this project was to design and prototype an affordable, mobile and more compact medical lifting device that can safely lift an immobile patient from a bed to a any given point without requiring an external electrical power source. The project aims to decrease the number of back injuries reported by nursing assistants, completing the lifting process mechanically opposed to manually. The final design was manufactured into a prototype made of Aluminum. In conclusion, the Medical Lifting prototype can lift up to 275 lbs. Additionally, when stored, fits inside a 33 in. X 25 in. X 60 in. cube. Finally, to increase the strength and safety of this device, the team made recommendations to redesign a more durable model in the future.
