Medical Injection Needle Stiffness Measuring Device
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
- Precision Compliance: Engineered to meet global medical standards, ensuring reliable results for needle manufacturers.
- High Accuracy: Deflection measurement (±0.01mm) and load control (±0.1N) guarantee precise evaluation of needle rigidity.
- Versatility: Supports all needle specifications (0.3mm–3.4mm) and wall types (normal, thin, ultra-thin).
- User-Friendly Design: Simplified setup and automated testing process reduce operational complexity.
- 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.
