33、(ISO) and has been taken over as EN ISO 8185:2009 by Technical Committee CEN/TC 215 “Respiratory and anaesthetic equipment” the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement,
34、at the latest by October 2009, and conflicting national standards shall be withdrawn at the latest by March 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any
35、 or all such patent rights. This document supersedes EN ISO 8185:2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive.

The General Standard is the basic st
39、andard for the safety of all medical electrical equipment used by, or under the supervision of, qualified personnel in the general medical and patient environment; it also contains certain requirements for reliable operation to ensure safety. The General Standard has associated Collateral Standards
40、and Particular Standards. The Collateral Standards include requirements for specific technologies and/or hazards and apply to all applicable equipment, such as medical systems, EMC, radiation protection in diagnostic X-ray equipment, software, etc. The Particular Standards apply to specific equipmen
41、t types, such as medical electron accelerators, high frequency surgical equipment, hospital beds, etc. NOTE Definitions of Collateral Standard and Particular Standard are found in IEC 60601-1:1988, 1.5 and A.2, respectively. To facilitate the use of this International Standard, the following draftin
42、g conventions have been applied. This International Standard uses the same main Clause titles and numbering as the General Standard, to facilitate cross-referencing of the requirements. The changes to the text of the General Standard are specified by the use of the following words. “Replacement” mea
43、ns that the indicated Clause or Subclause of the General Standard is replaced completely by the text of this International Standard. “Addition” means that the relevant text of this International Standard is supplementary to the requirements of the General Standard. “Amendment” means that existing te
44、xt of the General Standard is modified as indicated by the text of this International Standard. To avoid confusion with any amendments to the General Standard itself, a particular numbering has been employed for elements added by this International Standard: subclauses, tables and figures are number
45、ed starting from 101; additional list items are lettered aa), bb), etc. and additional annexes are lettered AA, BB, etc. In this International Standard, the following print types are used: requirements, compliance with which can be verified, and definitions: roman type; notes and examples: smaller r
46、oman type; description of type of document change and test methods: italic type; terms defined in the General Standard IEC 60601-1 :1988, Clause 2 or in this International Standard: bold type. Throughout this International Standard, text for which a rationale is provided in Annex AA is indicated by
47、an asterisk (*). 5DIN EN ISO 8185:2009-07 EN ISO 8185:2009 (E) Humidifiers are used to raise the water content of gases delivered to patients. Gases available for medical use do not contain sufficient moisture and can damage or irritate the respiratory tract or desiccate secretions of patients whose
48、 upper airways have been bypassed. Reduction of the relative humidity at the patient connection port can cause desiccation of tracheo-bronchial secretions in the tracheal or tracheostomy tube, and consequently may cause narrowing or even obstruction of the airway 19. Heat can be employed to increase
49、 the water output of the humidifier. In addition, many humidifiers utilise heated breathing tubes in order to increase operating efficiency and reduce water and heat loss. Ventilator and anaesthesia breathing tubes in common use might not withstand the heat generated by humidifiers and heated breathing tube mechanisms. Many humidifier manufacturers use off-the-shelf electrical connectors for their electrically-heated breathing tubes. However, since different manufacturers have used the sam
