(54) Hypodermic Injection System


(57) This invention is in the field of the injection of liquid into tissue by generating a high pressure jet capable of passing through the skin.
It is concerned with a hypodermic injection system for liquids comprising a medication container in which the liquid to be injected is located and which has two regions whereby the first region is squeezable or flexible and the second region contains at least one exiting orifice through which liquid can escape. The flexible region can be deformed by a pressure change in a surrounding container generated by an activatable gas generator and liquid is forced through at least one exiting orifice from the first container.
This invention is also directed to means for controlling the pressure of the liquid jet as well as medication containers which enable a sterile injection of medication.
