Abstract
A syringe pump including a syringe including a plunger that slides in a body which has a discharge port, a driving mechanism coupled to the syringe, including a cylinder in which a piston slides, and a plurality of biasing devices arranged about the piston operative to apply urging forces on the piston to drive the piston distally in the cylinder and thereby cause the plunger to slide in the body and discharge a substance found in the body through the discharge port, wherein if one of the biasing devices fails another of the biasing devices continues to apply a force on the piston to drive the piston distally in the cylinder, and a safety catch that initially prevents the biasing device from moving the piston, the safety catch being removable to permit the biasing device to move the piston.
