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