Abstract
A syringe includes a sleeve and a pressure vessel with high pressure fluid therein. The sleeve further comprises a sleeve piston. As the high pressure vessel contacts the sleeve piston, and a bump on the sleeve piston destroys the airtight status of the high pressure vessel. While the seal of the high pressure vessel is removed, the compressed fluid flows into the sleeve through the opening of the high pressure vessel and the hole of the sleeve piston. When the closed end of the sleeve moves closer to the closed end of the sleeve piston, the fluid in the sleeve is pressed and flows out of the sleeve through the sleeve hole of the sleeve.
