The work of preparing International Standards is normally carried out through ISO te
12、chnical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates close
13、ly with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria ne
14、eded for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

18、pproaches, intradermal acupuncture needles are recognized as an effective treatment for various disorders. Intradermal acupuncture needles are easy to use and especially effective when relatively long-lasting stimulation to a needling site is needed. Therefore, safety and sanitation considerations o
19、f intradermal acupuncture needles should be more carefully reviewed as well as their compatibility to human body.As a biomaterial, acupuncture needles can be corrosive and have potential to lose some of their mechanical characteristics. Furthermore, leachable substances can affect human tissue in an
20、y unintended, yet potentially harmful way. To address this problem, biomaterials should have no toxicity or produce any adverse effects, and should have appropriate mechanical characteristics such as tensile strength, elasticity, durability of abrasion and fatigue strength. In addition, the material
21、 should have a strong corrosion resistantability.This International Standard establishes an international standard for intradermal acupuncture needles. The characteristics of intradermal acupuncture needles include size, material, quality, tests, packing and identification through regulating marking
22、 methods. The standardization of the characteristics of intradermal acupuncture needles has potential to enhance the efficacy and improve the quality and safety of acupuncture treatments using intradermal acupuncture needles especially in regard to the biocompatibility for human body.

42、1 GeneralThe biocompatibility of the body of the needle, the tape and the coating shall be assessed and documented according to the guidance and principles given in ISO 10993-1.Compliance is demonstrated bya) analogy with published data,b) the selection of materials already shown to be biocompatible
43、 by proven clinical use in a similar application,c) experience with similar devices already on the market together with evidence of traceability to the materials used in the acupuncture needle, ord) compliance with published procedures for biological evaluation of medical devices.If the material of
44、the body of the needle or tape is changed and/or if there is a new coating applied to the surface of the needle body, and if there is risk that the new material or coating may cause adverse side effects to human tissue, then testing should be conducted in accordance with ISO 10993 series.5.2 Body of
45、 intradermal acupuncture needleThere is no uniform regulation regarding materials of the needle handle and body. Currently, the most popular material for the needle body consists of X5CrNi189, X7CrNi189 Austenite Stainless Steel, etc., which are listed in ISO 15510.6 Performance requirements6.1 Appe
46、arance and cleanlinessWhen observed under a microscope of low magnifications (10), the intradermal acupuncture needle shall not have roughness, grooves, rust, twist and/or bending. When observed under a microscope of medium or high magnifications (20 or higher), the tip of the needle shall not have
47、scars, foreign matters, broken or stumpy parts, bending, peeling surface coat and residual substances such as various solvents as used, fine metal particles which may be created in the process of cutting and grinding.6.2 Drawing strengthThe body of the needle shall be solidly joined to the handle of
48、 the needle.When the minimum static force given in Table 3 is applied in the direction of the centre axis of the body of the needle depending on the length of the body of the needle, it shall not be drawn out of the handle of the needle.Table 3 Force to test drawing strengthNomnial length of needle
