The anatomy of the syringe
Luer Lock Tip Generally used for injections requiring a secure connection of the syringe to another device. The tip is threaded for a “locking” fit, and is compatible with a variety of needles, catheters and other devices.
Luer Slip Tip A friction-fit connection that requires the clinician to insert the tip of the syringe into the needle hub of other luer connection in a push-and-twist manner. This will ensure a connection that is less likely to detach. Simply sliding the attachment device onto the syringe tip may not ensure a secure fitting.
Eccentric Luer Slip Tip Allows for work requiring closer proximity to the skin. Generally used for venipunctures and aspiration of fluids. (Also see luer slip instructions above.)
Catheter Tip Used for flushing (cleaning) catheters, gastrostomy tubes and other devices. Insert catheter tip securely into catheter or gastrostomy tube. If leakage occurs, refer to your facility’s guidelines.
Permanently Attached Needle Most commonly found in insulin and ‘tuberculin’ syringes. Permanently attached needles, also known as integral needles, reduce the ammount of medication waste and allow accurate mixing of different medications into one syringe.
