She escaped the staff room before an elderly male patient shut its door and confined the alleged attacker.
The man was charged with wounding with an intent to cause grievous bodily harm. He was refused bail and is expected to appear at Blacktown Local Court.
The Health Services Union said the "sickening" attack highlights the need for specialist security guards.
"Hospital staff go to work each day to care for the public and yet they are being treated as punching bags," HSU NSW secretary Gerard Hayes told AAP.
The union has pushed for 250 extra hospital security officers with "constable powers" since a police officer and a security guard were shot at Nepean Hospital in 2016.
"But all we get is talk," Mr Hayes said.
"It's time for action. Security officers must be employed with special constable powers. That means giving them the autonomy, authority and responsibility."
