Does anyone have advice on a pessary for mom with dementia?

My mom is moderate/advanced in dementia and has a pessary. She can still walk, so I'm able to get her to the doctor for her appointments to get the pessary cleaned or replaced. However, it is getting more difficult to get her to her appointments due to her mobility slowly getting worse and less steady on her feet. Are there doctors who can come to a memory care and clean/replace a pessary? My concern is her uterine/bladder prolapse needs the pessary. It is uncomfortable for her to go without one. I've already tried for her to go without it for a month or so, and she was uncomfortable, and the caregivers said her organs were hanging down. I'm not sure what I'm going to do when she can no longer go to the doctor to get it taken care of. Any advice is welcome and appreciated. Thank you so much in advance!
