YBB00092004 pre-filled injection needle tip puncture force tester test method
Pre-filled injection needles, including needles, needle holders, infusion tubes and protective sleeves, are a basic clinical nursing operation device. With the pre-filled injection needles used in clinical practice, the quality is good or bad. Directly related to people's physical health and life safety. Whether the puncture force of the pre-filled needle tip directly affects the adaptability of its use is one of the key indicators of various production enterprises.
" YBB00322004-2015 medical rubber plug puncture force test method" clearly stipulates: the test method of the infusion needle tip puncture force, using a puncture force test device to make the injection needle at a prescribed speed and vertically pass through the simulated skin. Peak force is used to evaluate the piercing force of the needle.
In the national standard YBB00092004-2015, the needle penetration force was clearly defined. Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. implemented the standard and required the development of a pre-filled needle tip puncture force tester CCY-02, also known as injection. Needle tip puncture force tester, medical needle tip puncture force tester, etc. The instrument is equipped with professional imported sensor, fully automatic operating system, micro printer, professional humanized fixture, which can complete the experiment quickly and accurately.
The pre-filled injection needle tip puncture force tester is used to detect the puncture force of the pre-filled injection needle tip. The detection operation method is as follows:
1. Place the test needle and simulated skin at 22 °C ± 2 °C for at least 24 h and test at the same temperature;
2. Clamp the appropriate size of the simulated skin c on the measuring device fixture without any significant stretching or contraction exerted on the simulated skin.
3. The needle to be inspected is mounted on the device b, the axis of which is perpendicular to the surface of the simulated skin c, and the needle tip points to the center of the circular puncture area.
4. Set the moving speed to 100mm/min.
5, start the test device
6. During the puncture of the membrane, the peak force or the recording force/displacement map is simultaneously measured.
Note: Do not use a membrane that has been pierced in a circular puncture area.
Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. has advanced testing technology, packaging testing equipment and professional laboratories, and is committed to providing comprehensive and superb packaging quality control solutions for industry customers.
