Accurate and Accurate Microliter Dosing Syringe

摘要

According to some embodiments, the syringe comprises a barrel, a delivery tube, a plunger seal disposed within the barrel, and a plunger rod assembly secured to the end of the barrel. The plunger rod assembly comprises a first plunger rod component including a first linear gear and a second plunger rod component at least partially disposed within the barrel and engaged with the plunger seal. . The second plunger rod component has a second linear gear, a first rotary gear having a plurality of teeth meshing with the first linear gear, and a plurality of second teeth meshing with the second linear gear. And a second rotating gear. The first rotating gear is coupled to the second rotating gear such that translational movement of the first plunger rod component translates the second plunger rod component.
