The BD Insyte-N™ Autoguard™ Shielded IV Cannula includes all of the features of the BD Insyte-N™ Autoguard™ Shielded IV Cannula in a 0.56-in cannula length. With the push of a button, the needle instantly retracts—reducing the risk of accidental needlestick injuries. The cannula is also made with BD Vialon™ Biomaterial, which is designed to recover after kinking to help provide longer dwell times and therefore, minimise restarts.
