17、cture treatment. Sterile acupuncture needles for single use are sterilized by the manufacturer, and the healthcare professional can open the sealed package and use the needle immediately.In order to encourage innovation, this International Standard does not enforce the combination of the needle diam
18、eter and length. However, considering the clinical usage requirements, the standard provides the specifications for the needle diameter and length.The sharpness and puncture performance of the needle tip are of very important clinical significance. Annex A states the guidelines and the evaluation me
19、thods for the intensity and the sharpness of the needle tip, while Annex B provides two qualitative and quantitative evaluation methods to determine the puncture performance of the needle tip.The qualitative methods to evaluate the puncture performance of needle tip are described in Annex B. The met
20、hods are simple, direct and practical. It makes them especially suitable for routine inspection and for cross-comparison of the acupuncture needles clinical applications. They also play a very important role in the enhancement of the quality of the needle tip. The methods to evaluate the puncture pe
21、rformance of the needle tip can be used to further evaluate the puncture and puncture performance of the acupuncture needle. Currently, the more appropriate method is to use the needle tip to pierce through polyurethane material; however, this method has not yet been implemented internationally.Cons
22、idering the consistency of standards in the future, this standard provides the methods to evaluate the puncture performance of the needle tip and ranks 5.3.5.2 as recommended. The standard does not provide the sharpness index of the piercing through polyurethane material by the needle tip. This inde
23、x will be added to the standard when it becomes appropriate. To improve product quality, all inspection reports should include the inspection information as well as the results of the performance evaluation.Since every manufacturers design, production, and sterilization methods are different, no reg
24、ulations exist for the materials of the acupuncture needle handle. Still, the needle body and the needle handle of acupuncture needle should have good biocompatibility. In order to ensure product safety and efficacy, the manufacturer should perform risk analysis and enforce risk management in additi
25、on to adhering to the requirements of local rules and regulations, the relevant background data of the medical devices and clinical practice throughout the entire duration of the products life cycle. ISO 14971 has provided manufacturers a framework for the effective management of hazards associated
26、with the use of medical devices.In some countries, the requirements proposed here are subject to legal sanctions. Such rules and regulations should take precedence over the standards set forth in this document. ISO 2014 All rights reserved vBS ISO 17218:2014BS ISO 17218:2014Sterile acupuncture needl
