Call the company that makes it or your meter, they provide replacements free of charge - the profit is in the disposable parts. They will probably send you a new one by first class post.
I have several finger pricking devices while I was trying to work out which was most comfortable to use. I'd be quite worried mine would break if I only had one even tho I don't use the others!
I'm aslso sure I saw someone post that they only used the lancet - without the pen. I have tried this too and managed to get blood, but I do prefer my device.
