Claim 0:
1. A syringe having a distal end for insertion into an injection site and a proximal end operable by a user comprising:
a syringe barrel having a distal end couplable to a needle and an open proximal end;
a plunger seal disposed inside the syringe barrel;
a plunger rod disposed in the syringe barrel extending along a longitudinal axis between a first end coupled to the plunger seal and a second end opposite of the first end;
a plunger extension coupled to the second end of the plunger rod moving in unison with the plunger rod, the plunger extension extending longitudinally from the second end of the plunger rod;
a compressible handle having a plurality of components, the plurality of components forming a first linked handle and a second linked handle disposed symmetrically in diametrical opposition about the barrel and the plunger rod;
the first linked handle having a first handle and a second handle, the first handle having a first length and the second handle having a second length different from the first length, the first handle having a proximal end flexibly coupled to the plunger extension and a distal end flexibly coupled to a proximal end of the second handle, and the second handle having a distal end flexibly coupled to a portion of the syringe barrel;
the second linked handle having a first handle and a second handle, the first handle having a first length and the second handle having a second length different from the first length, the first handle having a proximal end flexibly coupled to the plunger extension and a distal end flexibly coupled to a proximal end of the second handle, and the second handle having a distal end flexibly coupled to a portion of the syringe barrel;
wherein compressing the compressible handle causes the syringe plunger to move forwardly in the syringe barrel toward the needle to eject a medicament held in the syringe barrel.
