single-use medical devices designed for one-time application only, then discarded to prevent cross-contamination and ensure healthcare safety.
Structure and Materials
They typically consist of three main parts:
• Hub: Usually made of medical-grade polypropylene (PP), it provides a secure grip for healthcare workers and connects the needle to syringes or infusion sets.
• Cannula (Needle Tube): Crafted from high-quality austenitic stainless steel (e.g., SUS304), it offers excellent rigidity, corrosion resistance, and smoothness to minimize tissue damage.
• Protective Cap: A plastic cover that shields the needle tip from contamination before use.
Functions and Applications
They are used in conjunction with syringes or infusion sets for various medical procedures, including:
• Injecting medications (intradermal, subcutaneous, intramuscular, or intravenous injection).
• Drawing blood samples for laboratory testing.
• Administering fluids or nutrients via intravenous infusion.
Key Features
• Sterility: Sterilized by ethylene oxide (EO) to ensure they are free of bacteria and pyrogens (substances that cause fever).
• Sharpness: Most needles have a 4-beveled tip design, which ensures quick penetration, reduces patient pain, and minimizes tissue trauma.
• Easy Identification: Some hubs are color-coded by size, allowing healthcare workers to quickly select the correct needle for specific procedures.
• Safety: Single-use design eliminates the risk of infection transmission associated with reused needles (e.g., HIV, hepatitis B/C).
