Are there any devices that would help a caregiver to change a patient by herself?

There are lots of instructional videos on youtube about changing bedridden and immobile patients. Be careful not to hurt your own back and shoulders, so pay attention to safety practices.

This person who needs help should talk to a doctor or social worker about getting in-home help ordered. I am only 43 but could not lift, transfer, or support another adult person due to my own shoulder injuries!

I've read of other contraptions that can be used. But I did it the old fashion way ... with at least 3 firm heavy pillows. My mom was completely a vegetative state bedridden for several years. I've used blanket folded and set beneath her as a lifter to help me pull her to the center of the bed or up ( so that her feet is no longer touching the foot board). I've also used the lifter blanket to turn mom on her side so that I can clean her. Once I got her on the side, her body would try to fall to her back position. I had to quickly put 2 pillows over her legs and 1pillow behind her back/head. There have been previous discussions on this. I'm currently using the kindle and it's too time consuming to do a search on this. I can find it later on tonight..if I remember. Well...time to get up and start the day with changing bedridden dad's...

Pillows, the king size ones, with "firm" filling, along his back.

Just off the top of my head, can you put bedrails up and have the patient hold onto that supporting himself on his side? I understand he can't support himself long enough, just wondered if he could hold on to a bedrail. Another idea is to prop him up with pillows above and below the area she is working in. Maybe someone else can come up with other, better ideas.
