A sterile device consisting of a calibrated barrel (cylinder) with plunger intended to be used to administer an injection of insulin to a patient subcutaneously; a non-retractable needle is included, either attached or detached (usually capped for user protection). The syringe is typically made of plastic and silicone materials and will have plunger anti-sticking properties allowing smooth plunger movement. It can be used by healthcare personnel or patient, and will allow for the aspiration of the pharmaceutical from its container for direct administration to the patient or via an intravenous (IV) port, heparin lock, or saline lock. This is a single-use device.
