29、Terminal units are the points on a medical gas pipeline system where the operator makes connections and disconnections for the supply of specified medical gases to anaesthetic machines, lung ventilators or other items of medical equipment. A wrong connection can create a hazard to the patient or ope

30、rator. It is important that terminal units and their components be designed, manufactured, installed and maintained in such a way as to meet the basic requirements specified in this part of ISO 9170. This part of ISO 9170 pays particular attention to: suitability of materials; gas specificity; clean

31、liness; testing; identification; information supplied. This part of ISO 9170 specifies the provision of information for the installation and subsequent testing of terminal units prior to use. Testing of terminal units prior to use is critical to patient safety, and it is essential that terminal unit

32、s are not used until full testing in accordance with ISO 7396-1 has been completed. Annex A contains rationale statements for some of the requirements of this part of ISO 9170. The clauses and subclauses marked with an asterisk (*) after their number have corresponding rationale contained in Annex A

33、, included to provide additional insight into the reasoning that led to the requirements and recommendations that have been incorporated in this document. It is considered that knowledge of the reasons for the requirements will not only facilitate the proper application of this part of ISO 9170, but

34、 will expedite any subsequent revisions. 4DIN EN ISO 9170-1:2008-10 EN ISO 9170-1:2008 (E) 1 Scope 1.1 This part of ISO 9170 applies to: a) terminal units intended for use in medical gas pipeline systems in accordance with ISO 7396-1, for use with the following medical gases: oxygen; nitrous oxide;

35、medical air; carbon dioxide; oxygen/nitrous oxide mixture 50 %/50 % (by volume); b) terminal units intended for use in medical gas pipeline systems in accordance with ISO 7396-1, for use with the following gases and services: oxygen-enriched air; air for driving surgical tools; nitrogen for driving

36、surgical tools; vacuum. NOTE 1 Different names or symbols are used for air for driving surgical tools, such as instrument air, surgical air, air motor, air-700 and air-800. NOTE 2 The requirements of this part of ISO 9170 can be used as guidelines for terminal units for other gases. These other gase

37、s will be considered for inclusion in this part of ISO 9170 when they come into general use. It is intended especially to ensure the gas-specific assembly of terminal units and to prevent their interchange between different gases and services. 1.2 This part of ISO 9170 specifies requirements for ter

38、minal units for supply and disposal of nitrogen or air for driving surgical tools. 1.3 This part of ISO 9170 specifies requirements for probes intended to be connected to the gas-specific connection point which is part of the terminal unit. 5DIN EN ISO 9170-1:2008-10 EN ISO 9170-1:2008 (E) 1.4 This

39、part of ISO 9170 does not specify the dimensions of probes or of the gas-specific connection points of the terminal units. NOTE Certain regional or national standards specifying dimensions of probes and gas-specific connection points are given in the Bibliography. 1.5 This part of ISO 9170 does not

40、specify the dimensions of NIST connectors, which are defined in ISO 5359. 1.6 This part of ISO 9170 does not specify the dimensions of DISS connectors, which are defined in CGA V-51) 12. 1.7 This part of ISO 9170 does not specify the requirements for terminal units for anaesthetic gas scavenging sys

41、tems (AGSS), which are covered in ISO 9170-2. 2 * Normative references The following referenced documents are indispensable for the application of this document.
