Thank You to everyone for replying with suggestions and answers.

Unfortunately no good deed goes unpunished these days.

I visited the hospital to get some feedback on my idea and to possibly get an old nurse call button. I was disappointed with the CMA response I received. The hospital can not provide any equipment that has not been approved and in order to be approved the supplier and product must be listed. They thanked me for my generous offer but were not able to accept anything I brought in due to safety(And I suspect legal reasons)

The suggested I look into making a phone app that patients" loved ones could download and use while visiting...

Thanks again for the responses.
