Arterial & Venous Indwelling Needle: A Buyer's Guide for Medical Professionals


For healthcare providers seeking reliable vascular access solutions, Arterial & Venous Indwelling Needles are essential tools in modern medical practice. These specialized devices enable safe and prolonged access to blood vessels for monitoring, infusion therapy, or blood sampling. With China emerging as a major manufacturing hub, understanding how to source quality products becomes crucial.


How to Find Reliable Arterial & Venous Indwelling Needle from China in 2025


When sourcing from China, prioritize manufacturers with:

  • ISO 13485 certification for medical devices
  • FDA/CE approvals
  • Minimum 5 years production experience
  • OEM/ODM capabilities

Platforms like Alibaba verify suppliers through Gold Supplier status and Trade Assurance. Request product samples to evaluate needle sharpness, catheter flexibility, and connector security before bulk orders.


What Buyers Should Know Before Buying Arterial & Venous Indwelling Needle from China


Key considerations include:

  • Material quality (medical-grade stainless steel needles, polyurethane catheters)
  • Sterilization methods (EO gas preferred)
  • Minimum order quantities (typically 500-1,000 units)
  • Lead times (4-6 weeks for customized products)
  • Shipping options (air freight for urgent needs)

Always verify supplier credentials through video facility tours and third-party inspection reports.

Functions and features of Arterial & Venous Indwelling Needle


Modern designs incorporate:

  • Safety mechanisms (needle retraction/blunting)
  • Radiopaque stripes for X-ray visibility
  • Luer lock connectors
  • Hydrophilic coating for smooth insertion
  • Blood control valves

Premium models reduce complications like phlebitis (3.2% incidence vs. 8.7% in standard catheters according to 2023 clinical studies).


Scenarios of Arterial & Venous Indwelling Needle


These devices serve critical roles in:

  • ICU monitoring (continuous blood pressure measurement)
  • Chemotherapy administration
  • Emergency fluid resuscitation
  • Long-term antibiotic therapy
  • Hemodialysis access

In operating rooms, arterial lines help monitor real-time hemodynamics during major surgeries.


How to Choose Arterial & Venous Indwelling Needle


Selection criteria should consider:

  1. Patient factors: Age, vessel condition, treatment duration
  2. Clinical purpose: Blood sampling vs. rapid infusion
  3. Material compatibility: Some medications require polyurethane
  4. Dwell time: 72-hour vs. extended-duration catheters

For pediatric cases, 24G-26G needles with safety wings minimize trauma.
