The Smiths Medical Cleo Infusion set for subcutaneous continuous/intermittant infusion is an all-in-one needle inserter and retractor device (that completely encloses the needle), connector with tubing and dressing! Easy one-handed insertion and disconnection with the choice of 3 tubing lengths and 2 cannula lengths. No need to ever touch a needle or needle guide, and no need to manually insert or remove a needle! The casing that surround the inserter needle will automatically retract the needle into the inserter, locking it away securely and safely to prevent any accidntal needlestick injuries. When complying with Nursing Best Practice Guideline, CLEO is the clear choice!
