What are disposable syringe jet injectors (DSJI)?
A disposable syringe jet injector (DSJI) is a jet injector that uses single-use syringes. One syringe is used for each injection and is then discarded—it cannot be reused. Older models of jet injectors used the same pieces on different patients, which presented a risk of disease transmission through transference of body fluids. DSJIs improve the safety of immunizations and the safety of those administering them.
