Abstract
Methods for using precision low-dose, low-waste syringe configurations, which may have a reduced diameter lumen for dispensing 0.01 ml increments of contents. Methods may employ ergonomic attachments that improve the control and precision of the syringe. An attachment main body includes a gripping surface to permit a user to engage the attachment and move the attachment main body, and thus the syringe plunger relative to the syringe barrel using sliding movement. Methods may employ an assist feature on the attachment, which may be a traction wheel. Methods for using syringes with contents of higher viscosity may employ a pair of toothed pinion gears on a wheel and which cooperate with respective toothed racks formed on or fastened to the syringe body.
