Hmm well if you want to buy your own pump you have the choice of all the options,
I don't think there is an option to buy your own pump in the UK. It may be possible to go through a private consultant and get one but it is expensive - the cost of the pump is only the start.
As for having the "right" for a choice
@steveo4 , no I don't think you do. My hospital officially offer one pump because they only have to train their team on one pump, they only have to deal with one supplier, they can start new pumpers more often ... It is cheaper and convenient for them which, given the state of the NHS, I understand and support.
As
@Capt-Slog says, you can do your research and request something else. You may be lucky but it is not a given.
I too was lucky - soon after my request for a patch pump, my clinic was offered a Medtrum trial and I was their guinea pig. But it is not a right - I consider it a privilege.
If you want a patch pump, I recommend really doing your research and not settling on the first one you come across. There are more patch pumps available than the OmniPod. When I requested it at my clinic I was told that was the most expensive one.
Make your case (why should you have a patch pump?), review the options (look at all patch pumps) and consider the case from your clinic's perspective (why should they make more effort for you?).
