摘要： 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.

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.

摘要翻译： 本发明在通过产生能穿过皮肤的高压射流将液体注入组织的领域中。 涉及用于液体的皮下注射系统，其包括其中待注射的液体位于其中的药物容器，并且具有两个区域，由此第一区域是可挤压的或柔性的，并且第二区域包含至少一个出口孔 通过哪个液体可以逃脱。 柔性区域可以通过由可活化气体发生器产生的周围容器中的压力变化而变形，并且液体被迫通过来自第一容器的至少一个出口孔。 本发明还涉及用于控制液体射流的压力以及能够无菌注射药物的药物容器的装置。
