  • Hypodermic injection system
    Patent number: 6258063
    Abstract: A hypodermic injection system allows for the generation of a high pressure liquid jet capable of passing through the skin. The system uses two regions, the first region being flexible or squeezable and the second region having at least one exiting orifice through which the liquid jet can be expelled. The flexible region can be deformed by a pressure change in the surrounding container generated by an activatable gas generator that generates pressure within the first region that causes the liquid to be expelled.
