Medical needle toughness tester
The Medical Needle Toughness Tester is designed to evaluate the mechanical strength and flexibility of medical needles under bending stress. It features a 5.7-inch LCD touch display (120 × 90 mm) and supports testing of three types of needle walls: normal, thin, and ultra-thin. The device is manufactured in compliance with GB18457 (“Stainless steel needle for medical equipment manufacturing”), GB15811 (“Sterile disposable injection needle”), and ISO 9626 standards.
This tester is ideal for R&D, quality control, and production verification of disposable medical needles.
Application
(1) Medical disposable injection needles – evaluating bending durability before packaging.
(2) Insulin pen needles – testing ultra-thin walls for high flexibility without fracture.
(3) Vacutainer blood collection needles – ensuring mechanical reliability during insertion.
(4) IV infusion needles and cannulas – verifying structural integrity under repeated bending stress.
(5) Specialty surgical needles – quality assurance for orthopedic or microsurgical applications.
Standards
The device meets and supports testing according to the following international and national standards:
(1) GB15811 – Sterile disposable injection needle
(2) GB18457 – Stainless steel needle for medical equipment manufacturing
(3) ISO 9626 – Stainless steel needle for medical use
Features
(1) High-precision touch LCD interface for intuitive operation.
(2) Adjustable bending angles for normal, thin, and ultra-thin needle walls.
(3) Automatic bi-directional bending for standardized toughness testing.
(4) High-brightness 4-digit LED display for accurate parameter monitoring.
(5) Supports multiple syringe diameters (0.2–3.4 mm).
(6) Compact and robust design with net weight of 10 kg.
(7) Free perpetual upgrades according to national standards.
(8) Complete accessory kit included for immediate testing.
Test Procedure
(1) Fix one end of the needle tube firmly in the jig.
(2) Adjust the span according to needle wall type:
Normal wall: 25° bending
Thin wall: 20° bending
Ultra-thin wall: 15° bending
(3) Apply force at the specified span position, bi-directionally, 20 times at a frequency of 0.5 Hz.
(4) Observe the needle for breakage, deformation, or failure.
Principle: One end of the needle is fixed. A force is applied from the fixed point to the prescribed span, bending in one direction and then in the opposite direction, repeated for the defined number of cycles.
