Needle free connectors, also known as needleless connectors or Luer access devices, are medical devices used to provide a safe and convenient way to access and connect to IV lines, catheters, or other medical devices without the need for a needle puncture. They are designed to reduce the risk of needlestick injuries, promote infection control, and enhance patient comfort during medical procedures. Needle-free connectors typically consist of a housing or body with an internal mechanism that allows for the introduction or withdrawal of fluids or medications. They feature a male or female Luer lock or luer slip connection that can be easily attached to a compatible medical device or tubing.
