ANSI ES60601-1-2005 Medical electrical equipment-Part 1 General requirements for basic safety and essential performance (Consolidated Reprint C1 2009 Incorporating Amendment 1 2012.pdf

1、Association for the Advancement of Medical Instrumentationwww.aami.orgISBN 1-57020-246-XANSI/AAMI ES 60601-1:2005/(R)2012 reaching consensus on these tests can represent a considerable part of committee work. When a drafting committee determines that clinical concerns warrant the establishment of mi

2、nimum safety and performance criteria, referee tests must be provided and the reasons for establishing the criteria must be documented in the rationale. A recommended practice provides guidelines for the use, care, and/or processing of a medical device or system. A recommended practice does not addr

3、ess device performance per se, but rather procedures and practices that will help ensure that a device is used safely and effectively and that its performance will be maintained. Although a device standard is primarily directed to the manufacturer, it may also be of value to the potential purchaser

4、or user of the device as a frame of reference for device evaluation. Similarly, even though a recommended practice is usually oriented towards healthcare professionals, it may be useful to the manufacturer in better understanding the environment in which a medical device will be used. Also, some rec

5、ommended practices, while not addressing device performance criteria, provide guidelines to industrial personnel on such subjects as sterilization processing, methods of collecting data to establish safety and efficacy, human engineering, and other processing or evaluation techniques; such guideline

6、s may be useful to health care professionals in understanding industrial practices. In determining whether an AAMI standard or recommended practice is relevant to the specific needs of a potential user of the document, several important concepts must be recognized: All AAMI standards and recommended

7、 practices are voluntary (unless, of course, they are adopted by government regulatory or procurement authorities). The application of a standard or recommended practice is solely within the discretion and professional judgment of the user of the document. Each AAMI standard or recommended practice

8、reflects the collective expertise of a committee of health care professionals and industrial representatives, whose work has been reviewed nationally (and sometimes internationally). As such, the consensus recommendations embodied in a standard or recommended practice are intended to respond to clin

9、ical needs and, ultimately, to help ensure patient safety. A standard or recommended practice is limited, however, in the sense that it responds generally to perceived risks and conditions that may not always be relevant to specific situations. A standard or recommended practice is an important refe

10、rence in responsible decision-making, but it should never replace responsible decision-making. Despite periodic review and revision (at least once every five years), a standard or recommended practice is necessarily a static document applied to a dynamic technology. Therefore, a standards user must

11、carefully review the reasons why the document was initially developed and the specific rationale for each of its provisions. This review will reveal whether the document remains relevant to the specific needs of the user. Particular care should be taken in applying a product standard to existing dev

12、ices and equipment, and in applying a recommended practice to current procedures and practices. While observed or potential risks with existing equipment typically form the basis for the safety and performance criteria defined in a standard, professional judgment must be used in applying these crite

13、ria to existing equipment. No single source of information will serve to identify a particular product as “unsafe“. A voluntary standard can be used as one resource, but the ultimate decision as to product safety and efficacy must take into account the specifics of its utilization and, of course, co

14、st-benefit considerations. Similarly, a recommended practice should be analyzed in the context of the specific needs and resources of the individual institution or firm. Again, the rationale accompanying each AAMI standard and recommended practice is an excellent guide to the reasoning and data unde

15、rlying its provision. In summary, a standard or recommended practice is truly useful only when it is used in conjunction with other sources of information and policy guidance and in the context of professional experience and judgment. INTERPRETATIONS OF AAMI STANDARDS AND RECOMMENDED PRACTICES Reque

16、sts for interpretations of AAMI standards and recommended practices must be made in writing, to the AAMI Vice President, Standards Policy and Programs. An official interpretation must be approved by letter ballot of the originating committee and subsequently reviewed and approved by the AAMI Standar

17、ds Board. The interpretation will become official and representation of the Association only upon exhaustion of any appeals and upon publication of notice of interpretation in the “Standards Monitor“ section of the AAMI News. The Association for the Advancement of Medical Instrumentation disclaims r

18、esponsibility for any characterization or explanation of a standard or recommended practice which has not been developed and communicated in accordance with this procedure and which is not published, by appropriate notice, as an official interpretation in the AAMI News.

23、lectrical safety, essential performance AAMI Standard This Association for the Advancement of Medical Instrumentation (AAMI) standard implies a consensus of those substantially concerned with its scope and provisions. The existence of an AAMI standard does not in any respect preclude anyone, whether

24、 they have approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. AAMI standards are subject to periodic review, and users are cautioned to obtain the latest editions. CAUTION NOTICE: This AAMI standard may

25、 be revised or withdrawn at any time. AAMI procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication. Interested parties may obtain current information on all AAMI standards by calling or writing AAMI, or by visiting

26、the AAMI website at www.aami.org. All AAMI standards, recommended practices, technical information reports, and other types of technical documents developed by AAMI are voluntary, and their application is solely within the discretion and professional judgment of the user of the document. Occasionall

27、y, voluntary technical documents are adopted by government regulatory agencies or procurement authorities, in which case the adopting agency is responsible for enforcement of its rules and regulations.
