Abstract:
1. A syringe device comprising: a first syringe comprising: a first syringe barrel including an opening at a distal end thereof through which fluid may be forced or aspirated; and a first syringe plunger sliding within said first syringe barrel for forcing fluid through said first syringe barrel opening, said first syringe plunger including a stopper at a distal end thereof which sealingly and slidably engages said first barrel; a reciprocating member which moves along a track parallel to the axial direction of said first syringe; and a reciprocating device connecting said first syringe plunger to said reciprocating member so that when one member of the group consisting of said first syringe plunger and said reciprocating member moves proximally, the other member of said group is forced to move distally, wherein said first syringe plunger includes teeth on one side thereof, said reciprocating member comprises a plunger having teeth on one side thereof, and said reciprocating device comprises: a pulley post mounted on and extending axially from said first syringe barrel; a gear pulley rotatably mounted on said pulley post and having teeth for engaging said teeth on said first syringe plunger and said reciprocating member; a first retaining band fixed to said first syringe barrel and surrounding said first syringe plunger and said reciprocating member; and a second retaining band fixed to said reciprocating member and surrounding first syringe barrel; wherein, said syringe plunger includes a thumb rest at a proximal end thereof for allowing a user to push said first syringe plunger distally; wherein said reciprocating member includes a second thumb rest at a proximal end thereof for allowing the user to push said reciprocating member distally; and wherein said first syringe barrel includes first and second finger flanges for gripping by a user, said first and second finger flanges mounted on and extending laterally from a proximal end of said first syringe barrel.
