Generally speaking, this is easy to achieve. As long as we find something that meets the requirements, if it is really provided free of charge, we only accept the share of hospital income (of course, the cost of using this equipment should not be too expensive and affordable)? If there is nothing wrong with the machine, there is no reason not to succeed except that you have a personal vendetta with the hospital director, hehe.
Of course, more importantly, you need to see the dean's views on adding or replacing equipment in the conversation (which is related to his temper and his attitude towards managing the hospital), so as to reduce your chances of frustration.
