Requirements for w

25、ater treatment equipment are provided in ISO 26722. The verbal forms used in this International Standard conform to usage described in Annex H of the ISO/IEC Directives, Part 2:2004. For the purposes of this International standard, the auxiliary verb: “shall” means that compliance with a requirement

26、 or a test is mandatory for compliance with this International Standard; “should” means that compliance with a requirement or a test is recommended but is not mandatory for compliance with this International Standard; “may” is used to describe a permissible way to achieve compliance with a requireme

27、nt or test. This International Standard reflects the conscientious efforts of healthcare professionals, patients, and medical device manufacturers to develop recommendations for handling water and concentrates and for the production and monitoring of dialysis fluid for hemodialysis. This Internation

28、al Standard is directed towards the healthcare professionals involved in the management or routine care of hemodialysis patients and responsible for the quality of dialysis fluid. The recommendations contained in this International Standard might not be applicable in all circumstances and they are n

29、ot intended for regulatory application. The guidance provided by this International Standard should help protect hemodialysis patients from adverse effects arising from known chemical and microbial contaminants that might be found in improperly prepared dialysis fluid. However, the physician in char

30、ge of dialysis has the ultimate responsibility for ensuring that the dialysis fluid is correctly formulated and meets the requirements of all applicable quality standards. The concepts incorporated in this International Standard should not be considered inflexible or static. The recommendations pres

31、ented here should be reviewed periodically in order to assimilate increased understanding of the role of dialysis fluid purity in patient outcomes and technological developments. viii 2014 Association for the Advancement of Medical Instrumentation ANSI/AAMI 23500:2014 2014 Association for the Advanc

33、n the preparation of dialysis fluid for hemodialysis and related therapies and substitution fluid for use in online therapies, such as hemodiafiltration and hemofiltration. As such, this International Standard functions as a recommended practice. 1.2 Inclusions This International Standard addresses

34、the users responsibility for the dialysis fluid once the equipment used in its preparation has been delivered and installed. For the purposes of this International Standard, the dialysis fluid includes dialysis water (see 3.18 for definition) used for the preparation of dialysis fluid and substituti

35、on fluid, dialysis water used for the preparation of concentrates at the users facility, as well as concentrates and the final dialysis fluid and substitution fluid. The scope of this International Standard includes a) the quality management of equipment used to treat and distribute water used for t

36、he preparation of dialysis fluid and substitution fluid, from the point at which municipal water enters the dialysis facility to the point at which the final dialysis fluid enters the dialyzer or the point at which substitution fluid is infused, b) equipment used to prepare concentrate from powder o

37、r other highly concentrated media at a dialysis facility, and c) preparation of the final dialysis fluid or substitution fluid from dialysis water and concentrates. NOTE Because water used to prepare dialysis fluid is commonly prepared and distributed using the same equipment as the water used to re

38、process dialyzers, water used to reprocess dialyzers is also covered by this International Standard. 1.3 Exclusions This International Standard does not apply to sorbent-based dialysis fluid regeneration systems that regenerate and recirculate small volumes of dialysis fluid, systems for continuous

39、renal replacement therapy that use prepackaged solutions, and systems and solutions for peritoneal dialysis. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

47、vancement of Medical Instrumentation ANSI/AAMI 23500:2014 Note 1 to entry: Sodium bicarbonate is also known as sodium hydrogen carbonate. Note 2 to entry: Some bicarbonate concentrates also contain sodium chloride. Note 3 to entry: Bicarbonate concentrate may be in the form of a liquid or a dry powd
