Negative needle free connector is a high-safety connection device designed for modern medical infusion systems. It is widely used in scenarios such as intravenous infusion and injection window closure. Its core function is to significantly reduce the risk of infection and occupational exposure hazards in medical operations while ensuring efficient infusion through innovative structural design, providing double protection for patients and medical staff.
The product is made of medical-grade polymer materials, and the transparent shell is made of polycarbonate or copolyester, which has excellent visualization and mechanical strength. The completely metal-free design makes it MRI-compatible and can be safely used in magnetic resonance examination environments. It does not contain latex components and effectively avoids allergic risks. The product strictly follows the ISO 10993 international standard for biocompatibility to ensure safety when in contact with human tissue. Its fluid dynamics design can achieve a perfect flow rate of 350 ml/min under 1 meter of water pressure, meeting the needs of clinical efficient infusion.
In terms of infection control, the connector uses a number of breakthrough technologies: the smooth and flat surface characteristics facilitate thorough disinfection and wiping; the unique split diaphragm design and medical silicone seal form a reliable microbial barrier; the linear fluid path greatly reduces the possibility of blood residue and hemolysis; the optimized internal structure minimizes the dead space volume, thereby inhibiting the formation of biofilm. The product can withstand pressures up to 350 PSI and is compatible with the use requirements of power injectors.
As a key component of the negative pressure needle-free connection system, the product achieves zero needlestick operation through an intelligent valve mechanism, fundamentally eliminating the risk of occupational exposure caused by needlestick injuries. Its innovative negative pressure sealing technology can automatically close the channel when disconnected, preventing blood spillage and air embolism while maintaining the integrity of the infusion system. These features make it an ideal solution for improving patient safety and optimizing clinical workflow in modern intravenous therapy.
