Abstract
A device for measuring and regulating a volume of a fluid dispensed by a time-pressure dispenser, the device comprising: an adaptor for releasably coupling a syringe to the device, the syringe containing a fluid to be dispensed; a probe configured to be coupled with a piston of the syringe, the piston being operative to apply a pressure for ejecting the fluid from the syringe upon the application of an air pressure to the piston; and a displacement detector operative in use to determine a position of the probe so as to determine a position of the piston when dispensing the fluid, whereby to regulate the volume of the fluid dispensed from the syringe.
