My Mum has vascular Dementia, diagnosed 3 years ago, she had bladder cancer 8 years ago, and has a Stoma, she lives on her own, with carers gojng in. It's becoming so much more difficult with her Stoma, she's not able to change it any more, she doesn't understand why she needs her drainage bag at night, the bag is attached in the evening by carers, as soon as their gone, she detaches it, it fills up during the night, she's up during the night emptying it, so doesn't get a good nights sleep, but when she does have a good sleep the bag obviously leaks, bed and everything wet, she is distressed, carers or I come in the morning and sort everything out, have tryed taping the connections up, she can disconnect them, I've been in contact with her Stoma Nurse and Stoma suppliers, there is nothing out there like a child's lock, any idea's please, thank you
