  • Syringe having a mechanically operated mechanism for injecting precise volumes of a solution
    Patent number: 10933195
    Abstract: A syringe having a mechanical ejection mechanism. The ejection mechanism includes an actuator and a rotational gear. The actuator has a retractable pawl configured to engage the gear when the actuator is displaced from a non-depressed position into a depressed position. Displacement of the actuator causes the gear to rotate by a predetermined angle. The rotation of the gear is translated into linear displacement of the plunger within the barrel, thereby ejecting a predetermined amount of solution from the barrel.
