<p><P>PROBLEM TO BE SOLVED: To provide a novel air mixing injector which can take out even a small amount of content liquids in a state that the liquids are mixed with air, and is easy in reuse by pulling back a first piston. <P>SOLUTION: In the air mixing injector, the air of a first syringe 1 is pressure-fed by the first piston 2 arranged at a piston shaft 3, a second piston 8 accommodated in a second syringe 7 is driven by the air pressure-fed into the second syringe 7 which is attachable and detachable to/from the first syringe 1 by an effect that the air opens a check valve 6 while withstanding a biasing force of an elastic member 5, and the air is mixed into the content liquids. The first piston 2 is seated on the piston shaft 3 when the piston shaft 3 is pushed in and seals the inside of the first syringe 1, has a valve body 2b which is separated from the piston shaft 3 when the piston shaft 3 is pulled back and introduces the air into the first syringe 1, and constitutes an outside air introduction valve together with the piston shaft 3. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
