Get tested ...It isn't very likely but it may be possible. It never hurts to get tested. It is free and easy at your local clinic. Just a mouth swab will do it. I am sure you are fine but it is always better to be safe. It will put your mind at ease. Good Luck. Let us know how it goes.
Sorry about all that. As you get tested for HIV as Homerx has recommended, also get tested for Hepatitis C. HIV dies from about a minute to half minute after it hits the air. I doubt there was any HIV alive on the needle. I wish you well.
