Needle Free Injections

PATEV GmbH & Co KG Developed the PYROFAST: Needle-Free Injection
PYROFAST is an innovative needle-free injection system with novel pyrotechnical gas propulsion that provides accurate and comfortable drug delivery through the skin for intra-dermal, subcutaneous, and intra-muscular injections of liquid and solid (lyophilized) drugs. The needle-free injection occurs within 40 msec; a very fine, high-pressure jet stream of liquid medication painlessly penetrates the skin, depositing medication in the tissue beneath. The skin orifice caused by the jet stream is 4 times smaller than the orifice caused by a conventional needle injection. Therefore, needle-free injection reduces skin trauma and pain and leads to better patient compliance by eliminating patient's needle-phobia. PYROFAST allows patients to self-administer their injectable medication easily.


Benefits Summary: o painless o safe o user-friendly o fast absorption o eliminates needlesticks -- no sharps to dispose of o eliminates bleeding at the injection site
Application and Potential Advantage: Vaccines, epoetin, growth hormone, sex hormones, insulin, triptans, HIV medication, heparins, interferones, hyaluronic acid, analgesics, local anesthetics, etc.
Development Summary: Prototype devices have been developed and tested.

YROFAST has been already tested and is in the prototype phase. It consists of a reusable applicator made from metal or plastic, featuring a small battery that activates the gas generator and a trigger button, plus a disposable medication unit – pre-filled single-use and a single-use unit that takes dosage from an external source.
The battery provides thousands of injections per charge.

PYROFAST’s gas generator is inspired from technologies used to activate car airbags. There is a chemical substance used by the gas generator that starts to generate gas until it reaches a reliable pressure level which causes a plunger in the ampule to push the liquid through the orifice of the noozzle.
