Ma'zoor sleeping through an entire salaah period

Q: 

1. If the wudhu of a mazoor person (urine incontinence) sometimes, but not always, lasts through a short salaah period, namely maghrib, will he still be considered a mazoor? 

2. If he accidently sleeps through a salaah period, he will not know whether or not something exited, since movement is little during sleep, it's unlikely something exited, will he still be considered a mazoor?

Using a continuous glucose monitor

Q: I am, as per blood results and my doctor, on the brink of Type 2 diabetes. One of the options to try and reverse this is to use a continuous glucose monitor. What is the position with this in terms of ghusl? 

The patch is kept on for 14 days at a time and then changed. Please advise what is the position in terms of ghusl as if we are required to remove this in ghusl then it cannot work as each patch costs almost R1500 per 2 weeks.
