Claim:
1. An infusion device, comprising an IV medication reservoir, a syringe communicated to the IV medication reservoir and having a syringe plunger movable in a first syringe-filling direction, a filling plunger manually operable by an individual to engage the syringe plunger in a common housing and move the syringe plunger in the first syringe-filling direction to fill the syringe with medication and is movable independently of and unconnected to the syringe plunger when the filling plunger is manually moved in an opposite second syringe-discharging direction in the syringe housing after the syringe is filled, whereby medication cannot be inadvertently discharged from the syringe to the patient's IV by manually moving the filling plunger in the second syringe-discharging direction, and a biasing element for exerting bias on the syringe plunger when the syringe is filled and the filling plunger is manually released to move the syringe plunger in the second syringe-discharging direction to dispense an amount of medication per unit of time to a patient's IV.
