Can I use red-headed documents for patent declaration?

You can't. Because the patent statement does not meet the conditions of red-headed documents, it cannot be used. "Red-headed document" is not a legal term. "Red-headed documents" are named after "red heads" and often symbolize authority. It refers to non-legislative documents such as measures, instructions and orders issued by government agencies, and has long been an important starting point for administrative organs at all levels to implement administrative activities.
