Looking for basic medical sign language website

Does anyone know of a website that will show me some basic or commonly used medical terms/phrases in sign language. I post this in the patient safety forum because I believe this is a safety issue. If we cannot communicate at all with our patient, that's an issue!

I would like to be able to sign things about medications, allergies and be able to answer questions like when the doc will be in to see them or what time they will do an activity.

My facility has an interpreter only until the early evening, while the patient stays awake another few hours. This includes med pass time. While I'm able to ask their name, I can't communicate much else.

I'm aware that we can write back and forth, but that's difficult sometimes as our facility is for kids and not every kid can read and write well.

Thanks!!
