Needle Free Connector, Needle Free Valve & Needleless IV System - Sterile Medical IV Access Devices

Medical needleless connectors strictly adhere to the ISO 10993 biosecurity standards. The main body is made of a composite material of medical-grade polycarbonate (PC) and block polyether amide (PEBA), combining high strength with excellent flexibility. The surface is treated with a nano-silver ion coating. Leveraging the broad-spectrum antibacterial properties of silver ions, it can effectively inhibit the growth of common pathogenic bacteria such as Staphylococcus aureus and Escherichia coli, with an antibacterial rate of 99.9%. The internal sealing components are made of medical-grade silicone rubber, which is sterilized by gamma rays to ensure the absence of pyrogens and allergenicity, eliminating infection risks from the material source.

Optimized through Computational Fluid Dynamics (CFD) simulations, the internal channels of the needleless connectors feature a streamlined design, reducing fluid resistance by 30%. This effectively minimizes the risks of drug residue and thrombosis. The Innovative automatic valve closure system，upon disconnection of the infusion line, is driven by both a mechanical spring and fluid pressure, achieving rapid closure within 0.3 seconds. This prevents blood backflow and air entry, maintaining system airtightness. The connector interfaces strictly comply with the ISO 80369 international standards. The Luer-Lock structure design ensures a secure connection with devices such as syringes and infusion sets. Tested under a 15N axial tensile force, there is no disengagement, guaranteeing safety in clinical use.

A full-process quality control system compliant with the ISO 13485 quality management system has been established. Each needleless connector must pass 16 precise inspection procedures. Physical performance tests include connection strength tests (rotational torque ≥1.2N·m), opening and closing life tests (≥200 cycles without failure), and pressure resistance tests (withstand 300kPa pressure without leakage). Chemical performance tests use High-Performance Liquid Chromatography (HPLC) to analyze the compatibility between materials and drugs. Microbiological tests adhere to the USP 71 sterility test standards, ensuring that the product's sterility assurance level (SAL) reaches 10⁻⁶. Additionally, Scanning Electron Microscopy (SEM) is used to inspect the microstructure of the valve, ensuring the manufacturing precision of key components.

We offer needleless connectors in three pressure modes: positive pressure, negative pressure, and balanced pressure, adapting to different clinical scenarios. Positive pressure connectors release a small amount of positive pressure upon disconnection, effectively preventing tube blockages. Negative pressure connectors facilitate blood sampling. Balanced pressure connectors are suitable for multi-channel infusion management. The products are widely used in fields such as intravenous therapy, chemotherapy administration, and nutritional support. Especially in departments with extremely high infection control requirements, such as ICUs and neonatology departments, they can significantly reduce the incidence of Central Line-Associated Bloodstream Infections (CRBSI), providing safe and reliable guarantees for patients' intravenous therapy.
