"Getting a 24 hour heart monitor"

I received a 24 hour heart monitor and followed all the instructions of where and how to place the probes etc.   The next morning, on removing one of the probes it pulled or burned my skin leaving me with a sore 1 1/2" by 1 1/2" mark that turned septic.   I was worried as I have auto immune diseases and ended up having to buy antiseptic cream.  

The monitor had be put back in a wallet and you had forms on which there was personal information such as your name and hospital no.   On returning the monitor, my husband went to the first window where they are returned, and discovered at least five other envelopes, all with the monitors and personal details of patients which could so easily have been stolen at any time!   When my husband took the monitor into back to the window, he went into the hospital to report what he'd seen, i.e. the backlog of folders and monitors all within easy reach.  No one was in the room where they were and did not seem to have been for a while.   In the hospital my husband was told abruptly, "That's why the window is there, so people don't have to come in.". He then went back out of the corridor to the main reception and told the receptionist there.   Who said they'd ring someone up. My husband had noted on the folder it said about the different prices of monitors and the cost to the hospital if not returned. I also phoned my own doctors for advice about the mark and they said to contact the hospital, and tell them about the monitor, but when I did they wanted to put me straight through to that same department.
