VI friendly glucometer and possible funding sources?

From a consumer:

"I am working with a patient who is uninsured, blind and has diabetes. We are looking for a glucometer that can read the results aloud to her. Do you have, or know of, a charity program that can help her access this for free or low cost?"

Not really a candidate for a financial loan and TX has few for this particular situation. Are there any national sources for free or cost matching?
