Medical HDPE Plastic Puncture Needle Tubing with ISO13485

ISO 13485 Medical Extrusion HDPE Plastic Tip Tubing

Introduction

Material：HDPE（High-Density Polyethylene）

Processing Technic:The HDPE Puncture Needle mainly involve the processes of slotting and post-processing of the tip.

Performance Advantages and Medical Applications of Medical-Grade HDPE in Puncture Needles (Hubs/Components)

Performance Advantages

1. High Rigidity, Strength, and Dimensional Stability

• HDPE provides sufficient structural support, ensuring the needle hub does not deform or crack when connected to a syringe or subjected to operational forces, maintaining the overall stability of the puncture assembly.

2. Excellent Chemical Resistance and Biocompatibility

• Medical-grade HDPE can withstand various disinfectants (e.g., alcohol), medications, and bodily fluids without reacting or degrading. Its biocompatibility meets relevant medical standards, ensuring safety.

3. Good Processability and Low Cost

• HDPE is easily and precisely molded into complex hub structures through injection molding, suitable for mass production. This helps reduce the overall cost of single-use medical devices.

4. Lightweight

• Compared to metal hubs, HDPE hubs are extremely lightweight, helping to reduce operator hand fatigue, especially during prolonged or delicate procedures.

5. Excellent Barrier Properties

• It has low permeability to moisture vapor and gases, helping to maintain the sterility of the packaged product during its shelf life and protecting certain moisture-sensitive drugs.

6. Sterilizability

• It can be effectively sterilized using methods such as ethylene oxide or gamma radiation, making it suitable for single-use medical devices provided sterile.

Medical Applications

• Hubs for Single-Use Puncture Needles: This is the primary application. It connects the syringe to the needle cannula, providing a stable grip and handling point.

• Cannula/Sheath Component of Puncture Needles: In some designs (e.g., certain biopsy or drainage needles), an HDPE tube can serve as the cannula or outer sheath, remaining in place after the stylet is inserted to establish a channel.

• Protective Sheaths/Housings for Safety Engineered Syringes: Used to manufacture the outer shells of needle stick injury prevention devices.

• Components of Lumbar Puncture Needles and Bone Marrow Aspiration Needles: Used to manufacture the non-metallic parts of these specialized puncture instruments.

• Connectors for Infusion/Transfusion Sets: Flow regulation or connection components used in conjunction with puncture needles.
