AIRDIVIBER is a fully manual, spring-driven jet injector that requires no electricity, setting it apart from most existing devices that rely on power or are limited to cosmetic and restricted vaccine use. Designed specifically for crisis environments such as war or disaster zones, it enables both civilians and soldiers to administer essential treatment without professional assistance. The device employs needle-free jet-air technology, eliminating the risks of infection and accidental needle injuries. A simple dial mechanism allows users to select between nutritional, pain-relief, and infection-prevention ampoules, ensuring rapid and safe drug delivery even for untrained individuals. By combining power-free operation, needle-free safety, and intuitive usability, AIRDIVIBER provides a distinct solution for emergency medical care. It represents not only an improvement over conventional jet injectors but also a practical tool that enhances survival chances in environments where medical infrastructure is unavailable.
