Needle Penetration and Drag Force Tester

The Needle Penetration and Drag Force Tester (NPD-01) is a specialized testing instrument designed to evaluate the penetration and drag forces of hypodermic needles. This test is essential for assessing the performance, safety, and comfort of needles used in medical applications. Accurate testing of needle penetration force and drag force ensures the clinical effectiveness of hypodermic needles in penetrating the skin and moving through tissue, which is vital for patient comfort during injections and medical procedures.

Key Applications of the Needle Penetration and Drag Force Tester

The Needle Penetration and Drag Force Tester is critical in various industries, particularly in the medical sector, where hypodermic needles are commonly used. It is instrumental in:

• Medical device testing: Evaluating the performance of hypodermic needles to ensure patient comfort and clinical effectiveness.
• Pharmaceutical industry: Testing the penetration and drag forces of needles used in drug delivery systems.
• Medical device manufacturers: Ensuring compliance with international standards and regulations for needle performance.

Working Mechanism of the NPD-01 Needle Penetration and Drag Force Tester

The NPD-01 Needle Penetration and Drag Force Tester is equipped with a high-precision load cell that accurately measures the force exerted during needle insertion and movement through various substrates. The device is designed to hold a needle securely while moving it forward and backward at a controlled speed. This mechanism ensures accurate measurement of both the initial peak penetration force and the frictional drag force.

Testing Principle: How the Needle Penetration and Drag Force Tester Works

The Needle Penetration and Drag Force Tester operates based on the following test principles:

1. Penetration Force Measurement: The needle is inserted into a substrate at a constant speed, and the force required for insertion is recorded at various depths. This helps assess the initial peak penetration force.
2. Drag Force Measurement: During the test, the force required to move the needle through the substrate (i.e., the frictional drag force) is continuously measured.
3. Force Curve Analysis: The force data is presented as a function of penetration depth, allowing for detailed analysis of both the penetration and drag forces.

The test results provide essential information about the performance of hypodermic needles, influencing their design and ensuring they meet medical safety standards.

Key Technical Features of the Needle Penetration and Drag Force Tester

The NPD-01 Needle Penetration and Drag Force Tester is engineered with several advanced features to enhance testing precision and ease of use:

• PLC-Controlled Operation: The system is controlled via a programmable logic controller (PLC), ensuring precise test execution.
• 7-Inch HMI Touchscreen: Easy-to-use interface for test parameter input and real-time monitoring.
• Precision Ball Lead Screw: Provides smooth and accurate movement of the needle during testing.
• Adjustable Test Speed: Test speed can be varied between 1 mm/min to 500 mm/min, depending on test requirements.
• Overload Protection: The system is equipped with overload protection to safeguard against excessive forces.
• Automatic Test Return: After each test, the system automatically returns the needle to its starting position.
• Microprinter: Test results can be printed for documentation purposes, enhancing traceability and compliance.
