Abstract: An apparatus for injecting liquids into a body without using hypodermic needles, the liquid being ejected from a small orifice in a probe at a velocity which will penetrate the surface of a body against which the probe is placed. The apparatus ejects a specific small volume of the liquid under a very high initial velocity and pressure followed by the ejection of the main charge of liquid at a lower velocity so that the liquid flows into the channel caused by the initial penetration without penetrating to a greater depth. The probe is connected to a hand-held portion whose other end is attached via a flexible tube containing a suitable hydraulic fluid to two remote pressure intensifiers, one of which creates the required high initial pressure for a short period of time and the other of which provides the pressure necessary to eject the main charge of liquid at a lower velocity.
