Abstract
An infuser for dispensing medicaments to a patient at a preselected controlled flow rate. A housing unit is provided having a precalibrated flow control valve assembly portion sized to the desired flow rate. At the outer proximal end of the housing an outlet tubing or catheter is interconnected to the flow control valve assembly. A conventional syringe has its proximal end removably and sealably contained within the housing with its tip portion in sealingly mating engagement with the flow control valve assembly whereby the housing, syringe, and valve assembly are disposed in coaxial alignment. Elastomeric members are disposed on either side of the syringe and housing, each such member being anchored at opposed ends to the proximal end of the housing and the distal end of the syringe plunger. Restorative force applied to the syringe by the energy stored in the distended elastomeric members controls, over time, the force at which the plunger is introduced into the syringe housing, thereby controlling the infusion rate of the medicaments stored in the syringe.
