A system for infusing of fluid from a syringe, the syringe having a fluid containing cylinder, an outlet from the cylinder and a plunger adapted to translate into the cylinder to push fluid from the syringe through the outlet, the system comprising: a driver coupled to the plunger; a resistance force energizer interposed between said driver and the cylinder of the syringe, such that the resistance force energizer exerts a force on said driver pushing the plunger into the cylinder to efflux fluid from the outlet of the cylinder of the syringe; a body; said resistance force energizer at least partially contained within the body; a force applicator; said force applicator including a reciprocating arm with said driver at a proximal end, said resistance force energizer applying a force between said body and said force applicator to move said force applicator toward a resting point; said driver including a thrust area and a handle, said handle adapted for manual excursion of said force applicator against said resistance force energizer and away from said resting point of said force applicator, said excursion requiring manual input of energy to overcome said force applied by said resistance force energizer; said driver adapted to be selectively engaged with said syringe at said driver thrust area into an engaged state; and said driver, when engaged with the syringe, adapted to transfer forces from said force applicator to the syringe plunger, thereby pushing the syringe plunger distally into the syringe cylinder, forcing fluid out of the syringe, characterized in that said force applicator is adapted to undergo said excursion along a path with said driver thrust area of said driver of said force applicator spaced laterally from the plunger of the syringe, avoiding contacting said plunger of said syringe at a location of said engaged state and with the thrust area of the driver and to then be rotated to align into contact with the plunger of the syringe at said location of said engaged state. a driver coupled to the plunger; a resistance force energizer interposed between said driver and the cylinder of the syringe, such that the resistance force energizer exerts a force on said driver pushing the plunger into the cylinder to efflux fluid from the outlet of the cylinder of the syringe; a body; said resistance force energizer at least partially contained within the body; a force applicator; said force applicator including a reciprocating arm with said driver at a proximal end, said resistance force energizer applying a force between said body and said force applicator to move said force applicator toward a resting point; said driver including a thrust area and a handle, said handle adapted for manual excursion of said force applicator against said resistance force energizer and away from said resting point of said force applicator, said excursion requiring manual input of energy to overcome said force applied by said resistance force energizer; said driver adapted to be selectively engaged with said syringe at said driver thrust area into an engaged state; and said driver, when engaged with the syringe, adapted to transfer forces from said force applicator to the syringe plunger, thereby pushing the syringe plunger distally into the syringe cylinder, forcing fluid out of the syringe,
