Medical injection needle puncture force tester
The Medical Injection Needle Puncture Force Tester is a precision instrument designed to evaluate the puncture performance of medical needles. It simulates skin penetration and measures the maximum puncture force, providing reliable data for quality control, research, and production verification. Equipped with a 5.7-inch LCD touch screen, the device offers real-time force/displacement display, automatic data recording, and printing capability for accurate and repeatable measurements.
Application
This tester is suitable for a wide range of medical needle testing scenarios, including:
(1) Disposable medical injection needles – assessing sharpness and penetration performance.
(2) Insulin pen needles – evaluating puncture consistency and patient comfort.
(3) Blood collection needles (Vacutainer) – ensuring safe and reliable blood sampling.
(4) IV infusion needles and cannulas – testing ease of insertion and mechanical performance.
(5) Specialty surgical needles – evaluating microsurgical and orthopedic needle performance.
(6) Veterinary injection needles – verifying puncture efficiency and safety.
(7) Cosmetic or aesthetic needles – assessing penetration force and consistency.
Standards
The instrument complies with domestic and international standards for medical needle testing:
(1) GB15811-2016: Disposable sterile injection needles (China)
(2) ISO 17025: General requirements for the competence of testing and calibration laboratories (International)
(3) EN ISO 7864: Sterile hypodermic needles for single use (International)
(4) ASTM F2878-12: Standard Test Method for Puncture Resistance of Medical Needles (International)
Features
(1) Real-time display of puncture force and peak force for precise evaluation.
(2) 5.7-inch LCD touch screen with intuitive menu for simplified operation.
(3) Automatic data recording, printing, and analysis, including average force and deviation.
(4) Supports a wide range of needle diameters (0.3–1.2 mm) and wall thicknesses.
(5) Compact, portable, and lightweight, suitable for laboratory and production environments.
(6) Accurate simulated skin testing, compliant with GB15811 standards.
(7) Continuous software upgrade capability to align with updated national and international standards.

Test Procedures
(1) Condition the needle and simulated skin at 22°C ± 2°C for at least 24 hours.
(2) Clamp the simulated skin in the fixture, ensuring no stretching or compression.
(3) Mount the needle perpendicular to the surface of the simulated skin, tip centered on the puncture zone.
(4) Set the device moving speed to 100 mm/min.
(5) Start the test. The instrument records maximum puncture force and force/displacement curve in real time.
(6) Print or save test data for analysis, including peak force, F5 peak force, and average deviation.
Maintenance Information
(1) Keep the device and simulated skin clean and free from dust.
(2) Inspect clamps and simulated skin regularly for wear or damage.
(3) Calibrate the force sensor periodically to maintain accuracy.
(4) Store the instrument in a dry, temperature-stable environment.
(5) Follow local electrical safety regulations for proper grounding and operation.
