Claim:
A hand-held syringe, comprising: a syringe barrel comprising a fluid receptacle; a plunger comprising a head, wherein the head is disposed within the fluid receptacle of the syringe barrel, and wherein the plunger is movable relative to the syringe barrel along a longitudinal axis; and a handle, comprising: a first member comprising a first gripping end configured to be held by a first part of a user's hand, the first member further comprising a plunger attachment end pivotally connected directly to the plunger at a first pivot point so that the first member pivots about the first pivot point and relative to the plunger as the handle is used to move the plunger relative to the syringe barrel along the longitudinal axis; and a second member comprising a second gripping end configured to be held by a second part of the users hand, the second member further comprising a barrel attachment end pivotally connected directly to the syringe barrel at a second pivot point so that the second member pivots about the second pivot point and relative to the syringe barrel as the handle is used to move the plunger relative to the syringe barrel and along the longitudinal axis, wherein the first and second pivot points are substantially in-line with the longitudinal axis in a side view of the hand-held syringe; and a hinge pivotally connecting the first member to the second member at a location where the first member and the second member cross each other, wherein the first and second gripping ends of the handle each extend relative to the hinge onto one side of a reference axis that extends through the hinge and that is parallel with the longitudinal axis in the side view of the hand-held syringe, and wherein the plunger attachment end and the barrel attachment end of the first and second members, respectively, each extend relative to the hinge onto an opposite side of the reference axis in the side view of the hand-held syringe.
