IEC 60601 is a series of technical standards for the safety and essential performance of medical electrical equipment, published by the International Electrotechnical Commission. First published in 1977 and regularly updated and restructured, as of 2011 it consists of a general standard, about 10 collateral standards, and about 80 particular standards.
The general standard IEC 60601-1 – Medical electrical equipment – Part 1: General requirements for basic safety and essential performance – gives general requirements of the series of standards. 60601 is a widely accepted benchmark for medical electrical equipment and compliance with IEC60601-1 has become a requirement for the commercialisation of electrical medical equipment in many countries. [ citation needed ] Many companies view compliance with IEC 60601-1 as a requirement for most markets. This standard does not assure effectiveness of a medical device. In the US, evidence of effectiveness is required by the FDA and confirmed through either a Premarket Approval (PMA) [1] or similarity to a predicate device via a 510(k) Premarket Notification. [2]
National deviations of this series of standards exist which include country specific requirements; [3] [4] see e.g. UL or AAMI for US specifics. [5] [6]
The European EN and Canadian CSA versions of the standard are identical to the IEC standard.
In 2005, the third edition of IEC 60601-1 was published. It was the result of a comprehensive review of the second edition (dating from 1988). Some key changes are: the outline and the numbering scheme of the clauses and subclauses were changed, risk management was made much more relevant and the concept of essential performance was added. Currently (2012), the applicability of the second and third edition is somewhat overlapping [7] [8] depending on the products under consideration and the country/area of application. IEC 60601-1-11 (2010) must now be incorporated into the design and verification of a wide range of home use and point of care medical devices along with other applicable standards in the IEC 60601 3rd edition series. IEC 60601-1 merged to medical device directive 93/42/EEC which covers all IEC standard of electromedical & electrical safety so it is clear that EC cover all Previous IEC standard to medical device directive 93/42/EEC
The mandatory date for implementation of the EN European version of the standard is June 1, 2012. The US FDA requires the use of the standard on June 30, 2013, while Health Canada recently extended the required date from June 2012 to April 2013. The North American agencies will only require these standards for new device submissions, while the EU will take the more severe approach of requiring all applicable devices being placed on the market to consider the home healthcare standard. [9]
Requirements of 60601-1 may be overridden or bypassed by specific language in the standards for a particular product. Collateral standards (numbered 60601-1-X) define the requirements for certain aspects of safety and performance, e.g. Electromagnetic Disturbances (IEC 60601-1-2) or Protection for diagnostic use of X-rays (IEC 60601-1-3). Particular standards (numbered 60601-2-X) define the requirements for specific products or specific measurements built into products, e.g. MR scanners (IEC 60601-2-33) or Electroencephalograms (IEC 60601-2-26). [7] [8] Collaterals and Particulars may have their own revisions which are different from the General Standard.
A list of the collateral and particular standards currently in force follows: (last updated 15 September 2016)
For example, IEC 60601-1-9 for Environmentally Conscious Design of Medical Electrical Equipment published July 2007 is a collateral standard to IEC 60601-1 and has been developed drawing on extensive practical experience at Philips Medical Systems and Siemens Healthineers. The Part 9 standard asks manufacturers of medical devices to consider the environmental impacts of their devices throughout the product's entire life cycle and to minimize these where possible. The standard also requires that the manufacturer provide information to the user on how to use the product in the most environmentally sensitive way. The USA, Canada, Japan, Australia and New Zealand have not yet set transition dates for their national versions of this latest edition 60601-1, but the national versions published to date do contain the requirement to also conform with IEC 60601-1-9. However, the European version (EN 60601-1:2006) requires compliance with the new IEC 60601-1-9 collateral standard by September 2009.
According to the recent publication of the US national version of the collateral standard for products intended for home use, ANSI/AAMI HA60601-1-11, the application of the standard does not apply to the nursing home environment. In the United States, nursing facilities are considered to be environments providing professional healthcare. The American version of this collateral standard also places greater emphasis on a requirement that states that “inspection of the usability engineering file reinforce that the usability engineering process is necessary for validation of the instructions for use.” Devices typically mandated to use the new standard include oxygen concentrators, body-worn nerve and muscle stimulators, beds, sleep apnea monitors, and associated battery chargers prescribed for use at home. Although In Vitro Diagnostic devices such as blood glucose meters are being used by patients at home, the standard does not apply, as these devices remain under the jurisdiction of the more lenient IEC 61010 series[ citation needed ].
The 60601 certification process has been criticized for its complexity, cost, and the business risk it raises. This has been more particularly a concern during the transition to the third edition due to the indefinite adoption schedule of the new revision. [10] [11]
Biomedical engineering (BME) or medical engineering is the application of engineering principles and design concepts to medicine and biology for healthcare purposes. BME is also traditionally logical sciences to advance health care treatment, including diagnosis, monitoring, and therapy. Also included under the scope of a biomedical engineer is the management of current medical equipment in hospitals while adhering to relevant industry standards. This involves procurement, routine testing, preventive maintenance, and making equipment recommendations, a role also known as a Biomedical Equipment Technician (BMET) or as clinical engineering.
Medical software is any software item or system used within a medical context, such as:reducing the paperwork, tracking patient activity
The United States Federal Food, Drug, and Cosmetic Act is a set of laws passed by the United States Congress in 1938 giving authority to the U.S. Food and Drug Administration (FDA) to oversee the safety of food, drugs, medical devices, and cosmetics. A principal author of this law was Royal S. Copeland, a three-term U.S. senator from New York. In 1968, the Electronic Product Radiation Control provisions were added to the FD&C. Also in that year the FDA formed the Drug Efficacy Study Implementation (DESI) to incorporate into FD&C regulations the recommendations from a National Academy of Sciences investigation of effectiveness of previously marketed drugs. The act has been amended many times, most recently to add requirements about bioterrorism preparations.
A medical device is any device intended to be used for medical purposes. Significant potential for hazards are inherent when using a device for medical purposes and thus medical devices must be proved safe and effective with reasonable assurance before regulating governments allow marketing of the device in their country. As a general rule, as the associated risk of the device increases the amount of testing required to establish safety and efficacy also increases. Further, as associated risk increases the potential benefit to the patient must also increase.
IEC 61508 is an international standard published by the International Electrotechnical Commission consisting of methods on how to apply, design, deploy and maintain automatic protection systems called safety-related systems. It is titled Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems.
ISO 13485Medical devices -- Quality management systems -- Requirements for regulatory purposes is a voluntary standard, published by International Organization for Standardization (ISO) for the first time in 1996, and contains a comprehensive quality management system for the design and manufacture of medical devices. The latest version of this standard supersedes earlier documents such as EN 46001 and EN 46002 (1996), the previously published ISO 13485, and ISO 13488.
The Comparative Tracking Index (CTI) is used to measure the electrical breakdown (tracking) properties of an insulating material. Tracking is an electrical breakdown on the surface of an insulating material wherein an initial exposure to electrical arcing heat carbonizes the material. The carbonized areas are more conductive than the pristine insulator, increasing current flow, resulting in increased heat generation, and eventually the insulation becomes completely conductive.
In electrical engineering, electrical safety testing is essential to make sure electrical products and installations are safe. To meet this goal, governments and various technical bodies have developed electrical safety standards. All countries have their own electrical safety standards that must be complied with. To meet to these standards, electrical products and installations must pass electrical safety tests.
A surgical light – also referred to as an operating light or surgical lighthead – is a medical device intended to assist medical personnel during a surgical procedure by illuminating a local area or cavity of the patient. A combination of several surgical lights is often referred to as a “surgical light system”.
Network isolators are installed as part of a wired Ethernet system as galvanic isolators to reduce the potential for electrical injury and limit the extent of damage due to lightning strikes.
Functional safety is the part of the overall safety of a system or piece of equipment that depends on automatic protection operating correctly in response to its inputs or failure in a predictable manner (fail-safe). The automatic protection system should be designed to properly handle likely human errors, systematic errors, hardware failures and operational/environmental stress.
IEC 62304 – medical device software – software life cycle processes is an international standard published by the International Electrotechnical Commission (IEC). The standard specifies life cycle requirements for the development of medical software and software within medical devices. It has been adopted as national standards and therefore can be used as a benchmark to comply with regulatory requirements.
IEC 62366 medical devices - Application of usability engineering to medical devices is an international standard published by the International Electrotechnical Commission (IEC). The standard specifies usability requirements for the development of medical devices. It has been adopted as national standards and therefore can be used as a benchmark to comply with regulatory requirements.
CEBEC is a private Belgian rating label for the quality assurance of electrical appliances. Use of this label indicates that a piece of equipment conforms to European safety standards. The label is issued by SGS-CEBEC, now part of the SGS group. CEBEC has its own electrical testing laboratory located in Brussels. It is an approved laboratory for the purpose of certifications granted by SGS.
The Medical Device Regulation Act or Medical Device Amendments of 1976 was introduced by the 94th Congress of the United States. Congressman Paul G. Rogers and Senator Edward M. Kennedy were the chairperson sponsors of the medical device amendments. The Title 21 amendments were signed into law on May 28, 1976, by the 38th President of the United States Gerald R. Ford.
Due to the many regulations in the industry, the design of medical devices presents significant challenges from both engineering and legal perspectives.
