8、formation report (TIR) is a publication of the Association for the Advancement of Medical Instrumentation (AAMI) Standards Board that addresses a particular aspect of medical technology. Although the material presented in a TIR may need further evaluation by experts, releasing the information is val

9、uable because the industry and the professions have an immediate need for it. A TIR differs markedly from a standard or recommended practice, and readers should understand the differences between these documents. Standards and recommended practices are subject to a formal process of committee approv

10、al, public review, and resolution of all comments. This process of consensus is supervised by the AAMI Standards Board and, in the case of American National Standards, by the American National Standards Institute. A TIR is not subject to the same formal approval process as a standard. However, a TIR

11、 is approved for distribution by a technical committee and the AAMI Standards Board. Another difference is that, although both standards and TIRs are periodically reviewed, a standard must be acted onreaffirmed, revised, or withdrawnand the action formally approved usually every five years but at le

12、ast every 10 years. For a TIR, AAMI consults with a technical committee about five years after the publication date (and periodically thereafter) for guidance on whether the document is still usefulthat is, to check that the information is relevant or of historical value. If the information is not u

13、seful, the TIR is removed from circulation. A TIR may be developed because it is more responsive to underlying safety or performance issues than a standard or recommended practice, or because achieving consensus is extremely difficult or unlikely. Unlike a standard, a TIR permits the inclusion of di

14、ffering viewpoints on technical issues. CAUTION NOTICE: This AAMI TIR may be revised or withdrawn at any time. Because it addresses a rapidly evolving field or technology, readers are cautioned to ensure that they have also considered information that may be more recent than this document. All stand

Hansen, Johnson however, there may be a need to develop customized sterilization processes to sterilize medical devices or combinations of medical devices that pose

32、 a particular challenge to the pre-set sterilization processes. The designs and nature of materials used to construct medical devices are increasing in complexity. Materials used in the manufacture of sterile barrier systems and/or packaging systems and the combinations of different medical devices

33、in procedure sets can adversely affect conductivity, air removal and moist heat penetration, causing a failure to obtain the required sterility assurance level. The classification of a medical device into a product family can assist with the development of moist heat sterilization process conditions

34、 for this medical device. Assigning a medical device to a particular product family is the first stage of performance qualification at the point of use as specified in ISO 17665-1 and ISO/TS 17665-2. The efficacy of sterilization for a medical device using the sterilization process for that product

35、family should be assessed and documented together with any pre-treatments, such as cleaning, disinfection to reduce bioburden followed by lubrication and humidification of some materials e.g. those containing cellulose. In this part of ISO 17665 the attributes which relate to efficient sterilization

36、 and which are used to identify a product family have been selected from operational experience, engineering considerations and experimental data relating to the efficacy of the different types of moist heat sterilizers and their sterilization processes, and the types and design of differing medical

37、 devices and sterile barrier systems and/or packaging systems. Medical devices that are labelled by the manufacturer as being capable of being sterilized via moist heat may be categorized into product families by a user. However, not all medical devices will fit into one of the product families desc

38、ribed in this part of ISO 17665. In these cases, new product families will need to be identified based on the consideration of the products attributes and require additional performance qualification. Medical devices that have been classified into different product families are often processed in th

39、e same sterilization load when assembled into a randomly selected load configuration. This approach is common and acceptable in health care facilities where it is generally not feasible to qualify each sterilization load, provided that the sterilization process and sterilizer have been shown to be c

40、apable of sterilizing the range of product families constituting the sterilization load. Care should be taken to ensure that the combination of product families does not create a greater sterilization challenge than that set by the individual product families. In addition, consideration should be gi

41、ven to possible adverse interactions between medical devices such as the contamination of instruments with textile fibres. The examples shown in Annex B and D are illustrations of how the coding system is intended to be used in developing a sterilizer load. This part of ISO 17665 should be read in c
