Patent ID: 7118554

Claim:
A syringe device comprising: a first syringe comprising a first syringe barrel including an opening at a first end thereof through which fluid can be at least one of forced and aspirated, and a first syringe plunger configured to slidably move in an axial direction of said first syringe within said first syringe barrel so as to at least one of force and aspirate fluid through said first syringe barrel opening, said first syringe plunger including a stopper at a first end thereof, said stopper being configured to sealingly and slidably engage said first syringe barrel, said plunger including a first thumb rest at a second end thereof; a reciprocating member configured to move along a track substantially parallel to the axial direction of said first syringe, said reciprocating member having a second thumb rest at an end thereof; a reciprocating device operably connecting said first syringe plunger to said reciprocating member so that when said first syringe plunger moves in a first direction, the reciprocating member is urged in a second direction, the second direction being opposite to the first direction, and when said reciprocating member moves in the first direction, the first syringe plunger is urged in the second direction, the reciprocating device being different from fluid to be at least one of forced and aspirated through said first syringe barrel opening; and first and second finger flanges extending laterally from a second end of the first syringe barrel, said first and second finger flanges and said first and second thumb rests being configured to allow the syringe device to be operated by one hand.
