摘要： A hypodermic needleless injection system for injecting a liquid medication, which system comprises: a medication unit configured and dimensioned to store a volume of liquid to be injected, the medication unit having a first region and a second region that are in liquid communication with each other, the first region being deformable and the second region having at least one orifice, a hydrostatic chamber containing a hydrostatic pressure transfer medium, the hydrostatic chamber being so configured and dimensioned that the medication unit is located at least partially within the hydrostatic chamber and so that a pressure exerted on the transfer medium would cause the first region of the medication unit to deform so as to reduce the volume available for the liquid medication within the medication unit, and a first piston having a first end and a second end opposite to the first end, the first end having a surface which forms a closure of the hydrostatic chamber, and is adapted for applying a pressure on the transfer medium contained in the hydrostatic chamber.
