Device for at least one of injection or aspiration |
摘要 |
Devices, systems, and associated methods that facilitate the injection and/or aspiration of precisely controlled volumes of fluids at precisely controlled rates are provided. In some implementations, an apparatus may include a syringe and a lead screw connected to a plunger of the syringe. A ratchet gear may be connected to the lead screw. A mechanism may also be included to oscillate a frame in a direction perpendicular to a longitudinal axis of the lead screw such that one or more pawls of the frame engage the teeth of the ratchet gear in a manner that results in rotation of the ratchet gear in a single direction for controlled linear displacement of the plunger. |
