Car Airbags Inspire New Needle Free Injection System

, Pediatrics
Though needle free injection systems exist for a variety of medications, each still has its drawbacks for patient comfort or effectiveness of drug delivery. 
The Engineer is reporting that a German company called pervormanc has developed an injection system with technology adapted from car airbags that may overcome the disadvantages caused by modern spring and compressed gas systems. At the heart of the PYROFAST system is a chemical mix that, once activated, creates a continuous and even pressure profile to push the drug into the skin. The creators of the PYROFAST believe that it is the uneven pressure that creates irritation as the gas or spring adjust through the injection cycle, creating a type of turbulence under the skin. The new system is said to deliver a 40 msec even burst of liquid or solid drugs that should help overcome the irritating turbulence.
