Can you use a vacutainer needle without a safety lock on a different patient if its already been used on someone else? Also, is there a risk that the blood might clot in the needle, causing it not to work properly?

Even if the blood is flowing out and not in, is there still a risk of HIV transmission?

-It's very unlikely for HIV to be transmitted this way, as the virus does not survive long outside the body and requires direct access to your bloodstream. Since you didn't notice any cuts, the risk is extremely low. For peace of mind, you can ensure safe
