Manufactured with PUR material to ensure a more comfortable experience for the patient and a longer in-dwelling performance for the catheter. Reduce hit-and-miss insertion attempts by immediately confirming vessel entry, enabling you to stay focused on the insertion site. Design features RapidFlash instant flashback, which allows for catheter blood-flash observation, incorporated into 2024-gauge sizes. After threading, press the button, and the needle will instantly retract into the barrel chamber to help reduce accidental needlesticks and make sharps disposal easier.
