Revolutionizing Intravenous Connectivity

IV SafeT has re-imagined vascular access by inventing a medical device for a critical part of the intravenous (IV) pathway. The IV has had essentially no substantial changes to its functional parts for over 100 years - until now. IV SafeT has redesigned the luer lock, which secures the IV tubing to the IV catheter (the part in the body) or other IV tubing and accessories. The device is called the Lang Lock and it provides several unique features.


  • Smaller and lighter with an overall diminished footprint to decrease
    pressure against the skin

  • Anatomically correct with a flat surface against the skin 

  • Ease of use with ridged sides to grip and lock the tubing

  • Particularly well-suited for preemies and infants due to decreased size

  • Usable with any population
