It was just an example of an infinite, non-repeating number that still does not contain every other finite number

Another example could be 0.10100100010000100000… with the number of 0’s increasing by one every time. It never repeats, but it still doesn’t contain every other finite number.

Also hospitals in general are loath to replace any digital system that still works. That’s time that their already overworked personnel have to dedicate to learning new systems, potential new bugs and quirks that might have actual severe consequences for patients, etc.
