PATH Disposable Syringe Jet Injector (DSJI)

The PATH disposable-syringe jet injector (DSJI) is a sterile needle-free device that uses a single-dose syringe and a pressurized liquid stream rather than a needle to penetrate through the skin and deliver injections to the intradermal, subcutaneous, or intramuscular tissues. The PATH DSJI aims to reduce needle reuse and the associated disease spread due to shortages of sterile needles and trained lab workers. An estimated 23.5 million new HIV, hepatitis B, and hepatitis C infections occur every year through needle reuse and accidental needle stick injuries.
