Abstract

An injection device having a propulsion system having a container a compressible substance that when in a compressed state is a primary source of potential energy for propelling a fluid with sufficient pressure through an orifice of the container to create a jet enabling subcutaneous or intracutaneous delivery of the fluid. The potential energy is substantially a compression energy of the compressible substance. The device also including a pressure generating mechanism coupled to the container that compresses the compressible substance and that includes a rotatable member for exerting pressure on the compressible substance.
