Precision dispensing

Abstract

A syringe carriage is adapted to engage a syringe plunger and to slide relative to the syringe cartridge by user motion applied to a roller element that frictionally engages and rolls on a slide surface of the syringe cartridge, thereby facilitating precise movement of the syringe plunger relative to the syringe cartridge and thus precision dispensing of the syringe contents. The syringe cartridge may include a viewport a spine surface generally opposite the viewport and having indicia thereon. The spine surface, syringe lumen and viewport may provide for magnification of the indicia, through the syringe contents and viewport to the user. The syringe carriage may be releasably secured to the syringe cartridge using a flexible fastening assembly on the syringe cartridge, such that syringe cartridges may be installed and removed quickly and easily on the syringe carriage such that the syringe carriage may be used with multiple syringe cartridges and thus form kits.
