A sterile device consisting of a calibrated barrel (cylinder) with plunger intended to be used to administer (infuse) anaesthetic drugs. At the distal end of the barrel is a male Luer connector (typically a Luer-lock type) for the attachment of the female connector (hub) of a hypodermic needle, administration set or dental syringe cannula. It is typically made of plastic and silicone materials and may have anti-stick properties (internally precoated with compatible substances) that allow the plunger to move smoothly. This is a single-use device.
