    How to detect the puncture force of the needle tip? The penetration force of the injection needle is evaluated by the penetration force test device and the test speed with the specified injection needle.
    The maximum peak force measured when the needle passes vertically through the simulated skin at the speed.
    The professional device is the injection needle penetration force tester
    .

    Injection Needle Test Device - Simulated Skin, Injection Needle Penetration Force Tester CL15811-C Medical Injection Needle Penetration Force Tester One of the important means of needle
    .

    Specifications of CL15811-C Medical Injection Needle Penetration Force Tester: Test speed: 100±0.
    1mm/min; (stepless speed regulation can be set arbitrarily), average growth speed control accuracy ≤±5% (set value)
    .

    Pressure sensor range: 0~50 (0~5) N, accuracy ± 0.
    5% (full scale) CL15811-C medical injection needle puncture force tester injection needle puncture force simulation skin material Material: polyurethane film thickness: 0.
    35 mm ± 0.
    05 mm Shore hardness A (85 ± 10) exposed area: (after clamping) equal to 10 mm injection needle penetration force Simulated skin injection needle tip penetration force tester test procedure will be tested needle and simulated electronic skin at 22℃± Place at 2°C for at least 24 hours, and conduct analytical tests at the same ambient temperature
    .

    The test device clamps an appropriately sized mock skin to the fixture without applying any significant tensile or compressive force to the mock skin
    .

    The tester needle is mounted on the test device, its axis is perpendicular to the simulated skin surface, the needle tip points to the center of the circular puncture area, and the speed of the test device is set at 100mm/min
    .

    Start the test apparatus and, during membrane puncture, measure the maximum peak force or simultaneously record the force-displacement map, not by using a puncture to perform an area of ​​the membrane that has been punctured
    .

    CL15811-C Medical Injection Needle Needle Penetration Force Tester Injection needles are one of the commonly used medical devices in clinic.
    They are used to inject and absorb drugs.
    The injection needles belong to the hard stainless steel needle tubes used for medical devices
    .

    It is in direct contact with human skin and blood.
    In order to ensure the safety of users, the state has also carried out strict supervision on it, and has relevant national standards to regulate it
    .

    The puncture force of the injection needle is an important physical test index of the injection needle.
    The unqualified puncture force of the injection needle will increase the pain of the injected person during use, which will not only increase the pain degree of the patient, but also increase the work of the medical staff.
    amount
    .

    According to the national standard test standard: GB/T 15811-2016 Disposable sterile injection needle ISO 7864: 2016 Disposable sterile hypodermic needle requirements and test method requirements, the CL15811-C medical injection needle needle tip piercing was designed and developed force tester
    .

    This instrument is suitable for measuring the puncture force of injection needles and hard straight stainless steel needles of intradermal, subcutaneous, intramuscular, intravenous injection needles and other medical devices, mainly including injection needles, infusion needles, blood collection needles, acupuncture needles, indwelling needles and other medical devices.
