HOW DOES NEEDLE FREE TECHNOLOGY WORK?
MIT Needle Free Technology injectors use CO2 or compressed air to propel a microjet of liquid six times the size of a 30-gauge needle through the skin. Instead of feeling the piercing pain of the needle, the patient only feels a slight pressure as the propelled liquid passes through the skin.
Jet injection is 6 x smaller than a 30g needle. 33g needle the smallest in general medical use.
