31、/11/2010 07:03, Uncontrolled Copy, (c) BSIISO 7376:2009(E) iv ISO 2009 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried ou

32、t through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO co

33、llaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International

34、Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the element

35、s of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 7376 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment, Subcommittee SC 2, Tracheal tubes and other equipment. This second

36、edition cancels and replaces the first edition (ISO 7376:2003), which has been technically revised.

37、nal Standard gives requirements for laryngoscopes in tracheal intubation, hereinafter referred to as laryngoscopes, during anaesthesia, intensive care, emergency care and similar procedures, including requirements for reusable and single-use laryngoscope blades and handles. Laryngoscopes are manufac

38、tured in several forms and can, for example, be of single-piece handle and blade construction or have a detachable blade and handle. In the latter case, the light source for illuminating the larynx during use is either a lamp attached to a blade or a lamp in the handle with a light guide in the blad

39、e. The minimum illumination from the laryngoscope is defined/disclosed. The dimensions of laryngoscope blades are defined and disclosed to allow an informed decision by the operator to select the most appropriate instrument for intubation. Annexes A and B describe test methods. While Annexes C and D

40、 give blade markings and designs respectively, Annex E presents a rationale for certain subclauses in the main body of the document.

42、ngoscopes used for intubation, and specifies critical dimensions for the handle and lamp of hook-on type laryngoscopes. It also addresses the interchangeability of blades and handles. It is applicable only to instruments with an internal battery-operated power source for illuminating the larynx, sin

It is not applicable to surgical instruments known by the same generic name, nor is it applicable to flexible laryngoscopes or laryngoscopes designed for surgery, laryngoscopes powered

44、 from mains electricity supply, laryngoscopes connected by light-transmitting cables to external light sources, or video laryngoscopes designed to work with an external video system.
