German based medical firm Pervormanc claims that the airbag is the inspiration for its new "Pyrofast" needle free injection system. Making airbags more efficient nowadays addressing the idea of current gas or spring loaded air bag systems given its uneven application of pressure.

Dr. Thorsten Rudolph, who is working to commercialize the technology, describes it thusly:

"The pyrotechnical gas propulsion technology that is used doesn't cause bleeding, so the transfer of diseases such as HIV will be eliminated. This is the same chemical gas technology being used in airbags to provide a fast and reliable pressure profile. Including it in an injection system means that it can easily be used by patients to self administer drugs through the skin."
