Generally this is easy to accomplish, as long as you find one that matches the conditions, and if it's really offered for free and only charges the hospital a cut of the revenue generated by it (of course the cost of using the equipment can't be too expensive to make it affordable for the public)? And there's nothing wrong with the machine, there's no reason why it shouldn't work except that you have a personal vendetta against the director of the hospital, lol.
Of course, more importantly, in the course of the conversation you need to look at the dean's views on the addition or replacement of equipment (which relates to his temperament, his attitude towards the management of the hospital), which can reduce your chances of frustration
