Oh dear. I'm very far away, but wish I could help. Ask to see the hospital chaplain or social worker. Then write down that they need to find an ASL translator for you.

I can only fingerspell and know about 5 words. I can successfully sign "I want a cookie" and call you a "crazy tree" but I'm not good for much else! I had a deaf roommate in college who "borrowed" my ASL book and I never saw it again! Sigh.
