Sounds like the physical task of lugging a large man around is a big part of the burden. There are special beds with rails to avoid falls as well as hoists to move large long term bed ridden patients. I would get those two pieces of equipment. If you can not buy them new (they will be pricey), see if you can source them used from a family who does not need them any more.

Once you know how the equipment looks like that you need by shopping for it, you can even build some of it yourself, if you are strapped for cash. Bed rails are nothing magic and a hoist could be ceiling mounted on a rail or even based on an automotive engine hoist.

Just my two cents. I hope this helps,
