Abstract
A hand-held syringe includes a handle configured for suspending and using the syringe with a single hand. The handle includes pivotally connected first and second members. The members of the handle may be pivotally connected at intermediate positions along the lengths thereof or at or near ends thereof. The first member is associated with, and may be pivotally connected to, a syringe barrel, while the second member is associated with, and may be pivotally connected to, a syringe plunger. The syringe may be configured for a single-use (i.e., it may be disposable). Applications of use and methods of using a hand-held syringe are also disclosed.

1-20. (canceled)
A hand-held fluid delivery apparatus, comprising:
- a syringe comprising:
- a syringe barrel comprising a fluid receptacle;
- and
- a plunger disposable within the fluid receptacle of the syringe barrel and moveable along a length of the barrel along a longitudinal axis;
- and
- a handle comprising:
- a first member comprising a first gripping end and a plunger attachment end pivotally connected directly to the plunger;
- a second member comprising a second gripping end and a barrel attachment end pivotally connected directly to the syringe barrel;
- and
- a hinge pivotally connecting the first and second members of the handle at an intermediate location of each of the first and second members where the first and second members cross one another, the first and second members being assembled with one another and with the syringe in a manner that enables a single hand of a user to simultaneously grip both the first and second gripping ends, wherein movement of the first and second members toward one another displaces the plunger relative to the syringe barrel in a direction that reduces an available volume of the fluid receptacle to discharge fluid from the syringe barrel.
