Abstract
Devices, systems, and methods for volumetrically measuring syringe fluid are disclosed. In one aspect, a device for volumetrically measuring syringe fluid includes a reference plate, a flange adapter base attached at a first end of the reference plate for receiving a flange of a syringe, a plunger adapter disposed adjacent to a housing for receiving a plunger of the syringe, the plunger adapter being configured to slidingly move along a length of the reference plate, a displacement sensor disposed in the housing and configured to measure a displacement of the plunger adapter in relation to the flange adapter base as the plunger adapter is slid along the length of the reference plate, and a displacement conversion mechanism disposed in the housing and configured to convert the displacement measurement of the plunger adapter to a volumetric measurement in order to determine a volume of fluid the syringe has drawn in.
