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