I know that I have posted this before.
All of our love ones want us to stay close and be able to call us when they have a need. I have found the most unusual gadget for my loved one to be able to just push a button and I go running. It is a cordless door bell from Walmart. I taped the small ringer to the rail of his hospital bed. When he needs something, I can hear it ring no mater what room I am in around our house. The cost was only $10.00. You can get one with more than one button for them to push which allows for one in the den (where he eats), and one in the bedroom. I am temped to put one in the bathroom.
I was walking around Walmart looking for a bell he could ring when an employee suggested the door bell.
