Medical injection needle rigidity tester

Standard

GB 18457-2001

This standard mandates precise control over needle wall thickness (normal, thin, ultra-thin) and rigidity performance, directly impacting patient comfort by minimizing pain during injections.

Product Advantages

  1. Precision Compliance: Engineered to meet global medical standards, ensuring reliable results for needle manufacturers.
  2. High Accuracy: Deflection measurement (±0.01mm) and load control (±0.1N) guarantee precise evaluation of needle rigidity.
  3. Versatility: Supports all needle specifications (0.3mm–3.4mm) and wall types (normal, thin, ultra-thin).
  4. User-Friendly Design: Simplified setup and automated testing process reduce operational complexity.
  5. Durability: Compact, robust construction (25kg) with lifetime free upgrades aligned with national standards.

Product Features

  • Advanced Testing Principle: Measures needle deflection by applying a vertical force at the center of a defined span, simulating real-world stress conditions.
  • Comprehensive Kit: Includes a main testing unit, calibration weights, specialized jigs, and a printer for instant data documentation.
  • Adjustable Parameters: Customizable span distance (0–55mm) and loading speed (1mm/min ±0.1mm/min) to accommodate diverse needle types.
  • Safety & Compliance: Ensures needles meet rigidity thresholds to prevent bending during use, enhancing patient safety.
  • Ergonomic Design: Compact dimensions (460mm×340mm×400mm) optimize laboratory workspace efficiency.
