An assembly is provided which includes an infusion device coupled to a standard medication syringe. The medication syringe may be coupled to a stopcock valve having multiple ports and to which syringes, vial adapters, infusion tubing, and multiple other items may be coupled. The infusion device includes a source of power based on a resistance force such as vacuum, spring or gas power. The infusion device converts the resistance based force to usable work in the form of a force applicator. The force applicator includes a driver section on one section of a reciprocating arm and an attachment to the power source on another section of the arm. The driver is pulled outward (excursion) to increase the size of the chamber, creating a force that tends to return the driver back inward, causing incursion. The driver can be attached removably to the syringe plunger to induce the infusion process. |

1. A non-electric system for medicament infusion, the system comprising:
at least one infusion device adapted to be coupled lateral to at least one medicament syringe; said medicament syringe including a cylinder and an elongate plunger assembly, said assembly comprised of an actuating rod with a distally positioned piston opposite a proximal terminus, said piston adapted to sealingly slide within said cylinder, said cylinder including a distal cylinder portion positioned distal to said piston, said distal cylinder capable of containing medicament and having at least one fluid conveyance port communicating with said distal cylinder portion; said infusion device comprising a body, a resistance force energizer, and a force applicator, said force applicator including a reciprocating arm with a 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 surface and a handle, said handle grippable 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 or disengaged with said syringe proximal terminus at said driver thrust surface; said driver, when engaged with said syringe proximal terminus, adapted to transfer forces from said force applicator to said syringe plunger assembly, thereby pushing said syringe piston distally into said syringe distal cylinder portion, forcing medicament efflux through said fluid conveyance port; wherein said medicament syringe is coupled to a patient infusion interface, said interface including a flow regulator and terminal connector, said flow regulator adapted to influence the rate of medicament flow; and wherein a fluid control valve with at least two peripheral ports is coupled between the syringe distal port and said patient infusion interface, said valve including a generally circular cross sectional body having a recess therein with said ports along said periphery oriented in a common plane and accessing said recess; and a manifold hub rotatably supported within said recess, said manifold hub with fluid flow paths therein, said manifold hub rotatable to selectively connect said ports of said valve together through said fluid flow paths. |
