Positive needle free connector is a key medical device used to connect vascular access devices (VADs) and is widely used in clinical operations such as infusion, injection or aspiration. It significantly reduces the risk of needlestick injuries to medical staff through needleless technology, while reducing the possibility of catheter-related infections. The connector uses a high-quality silicone shell to ensure excellent sealing and effectively prevent bubbles, liquids or foreign objects from entering the pipeline system, thereby ensuring patient safety.
Its core advantage lies in the positive pressure design, which can avoid blood backflow during syringe aspiration, prevent thrombosis at the tip of the catheter, and reduce the risk of catheter blockage. The connector shell is impregnated with PCAg+ antibacterial material to further inhibit bacterial growth and improve the level of infection control. The stem at the injection port adopts a protruding design, which meets strict infection control standards and ensures safe and reliable operation.
In addition, the connector is equipped with a high-quality spring inside, which supports multiple punctures without leakage and extends its service life. The double sealing ring design at the upper and lower ends effectively isolates air, liquid and external contaminants to keep the pipeline clean. The linear fluid path reduces turbulence, complies with standard infusion protocols, and ensures the stability of drug delivery. The residual liquid volume is extremely low, less than 0.06 ml, minimizing drug waste and contamination risks. These features make it an ideal choice for clinical vascular access management.
