Abstract

A drive train (110) for advancing a syringe plunger (132) in at least one direction is disclosed (e.g., to deliver fluid). This drive train (110) includes a first drive source (116a) and a second drive source (116b). The advancement of the syringe plunger (132) is dependent upon the output (118a) of the first drive source (116a), as well as on the output (118b) of the second drive source (116b). The sum of the outputs (118a, 118b) may be used to advance the syringe plunger (132), the differential of these outputs (118a, 118b) may be used to advance the syringe plunger (132), or each of the outputs (118a, 118b) may be made available to individually advance the syringe plunger (132).
