"Barney, he's a central access device trainer, so nurses can learn safely on a medical device how to do certain procedures involving central access lines on patients. So the initial idea came about 12 months ago and it was about 8 months of development. During that time we had a prototype device circulating in the hospital with nurses and then following the prototype, so maybe about 12 months after the idea, we had the first version out. The 3D printed version means that we can have high turnaround, it only takes about two and a half days to print each device which means that we can get them out to more people to do their training on. So Arnie came from a collaboration from different teams involving the simulation, engineering and clinical nursing education team. We all worked together to work on the different components and parts of the Arnie so it was a real bespoke device that was purpose built for training within our region."
