The anaesthetic gas scavenging system comprises three main parts: a transfer system, a receiving system,
31、and a disposal system. A schematic diagram of typical anaesthetic gas scavenging systems is shown in Figure 1. Requirements for receiving systems and transfer systems are specified in ISO 8835-3. Type-specific connections for terminal units are specified in ISO 9170-2. In this part of ISO 7396, spec
32、ifications and test procedures are given to ensure compatibility between the components of the system. This part of ISO 7396 specifies requirements for pipelines for anaesthetic gas scavenging systems for anaesthetic gases and vapours. It is intended for use by those persons involved in the design,
33、construction, inspection and operation of healthcare facilities treating human beings. It is advisable that those persons involved in the design, manufacture and testing of equipment intended to be connected to pipeline systems also be aware of the contents of this part of ISO 7396. Specific compone
34、nts are used for scavenging terminal units and for other connectors which are intended to be used by the operator. In addition, the system is tested and certified to operate at safe flows and without leakage. It is also intended to address issues of patient safety. The objectives of this part of ISO
35、 7396 are to ensure the following: a) avoidance of cross connections between different pipeline systems; b) continuity of function of the system; c) use of suitable materials; d) cleanliness of components; e) correct installation; f) provision of indicating system(s); g) correct marking of the pipel
36、ine system and components; h) testing, commissioning and certification; i) correct operational management. Annex E contains rationale statements for some of the requirements of this part of ISO 7396. It is included to provide additional insight into the reasoning that led to the requirements and rec
37、ommendations that have been incorporated in this part of ISO 7396. The clauses and subclauses marked with (*) after their number have corresponding rationale contained in Annex E. 4 EN ISO 7396-2:2007 (E) 1 Scope This part of ISO 7396 specifies requirements for the design, installation, function, pe
38、rformance, documentation, testing and commissioning of anaesthetic gas scavenging disposal systems to ensure patient safety and to minimize exposure of the operator and other persons to anaesthetic gases and vapours. It includes requirements for the power device, pipeline system, performance, non-in
39、terchangeability between key components and avoidance of cross connections between anaesthetic gas scavenging (AGS) disposal systems and medical gas and vacuum pipeline systems. NOTE In this part of ISO 7396, the term “pipeline” refers exclusively to pipelines that are part of a dedicated anaestheti
40、c gas scavenging system (AGSS). This part of ISO 7396 is applicable only to those disposal systems intended to be connected via AGSS terminal units conforming to ISO 9170-2 and to AGSS receiving systems conforming to ISO 8835-3. This part of ISO 7396 also applies to: extensions of existing AGSS disp
41、osal systems; modifications of existing AGSS disposal systems; modifications or replacement of power devices. 2 Normative references The following referenced documents are indispensable for the application of this document.
