Revolutionizing Medical Device Testing: Advanced Resilience Tester for Blood Collection Needles

Medical device manufacturers now have access to a cutting-edge resilience testing solution specifically engineered for blood collection needle rubber sleeves. This innovative system ensures critical sealing performance through precise measurement of post-compression dimensional recovery, addressing FDA Quality System Regulation (QSR) requirements while enhancing patient safety.

Compliance & Precision Engineering

The tester adheres to stringent international standards including ISO 80369 (needle dimensions), ISO 11040 (hypodermic needle caps), and ISO 7886 (injection systems). Its advanced laser displacement sensor, with ±0.01mm accuracy, guarantees reliable data collection during rigorous testing protocols. The system offers adjustable compression force from 5-50N and deflection testing up to 50% of sleeve diameter, with programmable cycles from 1 to 10,000 repetitions.

Operational Excellence

Powered by a pneumatic actuation system, the tester simulates clinical insertion forces by compressing sleeves between parallel plates. Real-time dimensional analysis via high-resolution imaging and force monitoring enables comprehensive fatigue assessment. Proprietary algorithms calculate resilience as percentage recovery from compressed states, providing actionable material optimization insights.

Multi-Modal Testing Capabilities

The system performs three critical assessments:

• Compression-Rebound Cycling: Evaluates material fatigue resistance under repeated stress
• Dynamic Stress Relaxation: Quantifies creep deformation under sustained loading
• Post-Compression Geometry Analysis: Validates dimensional stability for functional integrity

This integrated solution empowers manufacturers to develop next-generation needle sleeves with superior sealing characteristics, ensuring compliance with global medical device standards.
