of size designation of tracheostomy tubes made of plastics materials and/or rubber EN ISO 5366-1 gives requirements for adult tracheostomy tubes made of plastics materials and/or rubber This document gives requirements for paediatric tracheostomy tubes with an inside diameter from 2,0 mm to 6,0 mm Paediatric tracheostomy tubes are primarily intended for use with infants and children who may require anaesthesia, artificial ventilation, relief of upper airway obstruction or other respiratory therapy An infant or child differs from an adult, not only in size but especially with regard to airway anatomy and respiratory physiology; thus airway equipment for paediatric patients differs from that for adults in size and also in basic design It should be noted that, although this document gives some requirements for cuffs, cuffs are seldom provided on the smaller sizes of paediatric tubes This document gives requirements for those characteristics of tracheostomy tubes that can be standardized and which are important for patient safety It does not require the connector to be permanently attached to the tube, as this may be impractical with infants and small children Other acceptable methods of connecting these components are available, and this document makes provision for them This document does not limit the range of tube designs needed to match the variety of paediatric anatomy, lesions and space limitations encountered The method of describing tube dimensions and configuration has been devised with the aim of assisting the clinician in the selection of a suitable tube to conform as far as possible to a particular patient's anatomy Size is designated by inside diameter, which is important because of its relation to resistance to gas flow Because the stomal and tracheal diameters are important when selecting tubes, it is considered essential that the outside diameter be stated for each size of tube ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ A tracheostomy tube can increase resistance to gas flow For tubes with a given outside diameter, differences in wall thickness have a major influence on the resistance to gas flow, especially in the smaller sizes of paediatric tracheostomy tubes Flammability of tracheostomy tubes, for example if flammable anaesthetics, electrosurgical units or lasers are used in oxidant-enriched atmospheres, is a well-recognized hazard addressed by appropriate clinical management, which is outside the scope of this document 1See ISO/TR 11991 标准分享网 www.bzfxw.com 免费下载 Licensed Copy: athen reading, Reading University Library,

method for determining the resting diameter of the cuff B.1 Principle The resting diameter of the cuff is measured when the cuff is inflated with a pressure which is intended to remove creases but to minimize stretching of its walls B.2 Apparatus B.2.1 Means to inflate the cuff with sufficient air to create an internal overpressure of 2,0 kPa ± % B.3 Procedure B.3.1 Inflate the cuff with sufficient air to create an internal overpressure of 2,0 kPa ± % and leave to stabilize for at (23 ± 2) ºC, at not less than 80 % relative humidity, maintaining that overpressure B.3.2 Locate the plane of maximum cuff diameters perpendicular to the axis of the tube Measure the four cuff diameters at intervals of 45º in the located plane ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ B.4 Expression of results Calculate the arithmetic mean of the measurements obtained in B.3.2 and express the result in millimetres 16 标准分享网 www.bzfxw.com 免费下载 Licensed Copy: athen reading, Reading University Library, 31/01/2010 05:17,

tubes should have sufficient rigidity to allow the construction of a tube with the thinnest possible wall which, at the same time, maintains resistance to kinking When in place it should be flexible and soft enough to conform to the patient's anatomy without exerting undue pressure on the body tissues C.1.2 Unless intended and marked for single use, tracheostomy tubes should be reasonably resistant to deterioration by methods of cleaning, disinfection and sterilization as recommended by the manufacturer Such tubes should withstand accepted methods of steam sterilization The recommended method or methods of sterilization should not produce changes in the tube material which will compromise the biological safety of the tracheostomy tube (see Clause 5) C.1.3 Tracheostomy tubes under normal conditions of use should be reasonably resistant to deterioration by clinically used concentrations of anaesthetic vapours and gases ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ C.1.4 Tracheostomy tubes should be readily detectable by X-ray either by the nature of the material of which they are made or by the provision of a marker at the patient end C.1.5 When not in use the tracheostomy tube should maintain its intended shape when stored in accordance with the manufacturer's instructions C.2 Design C.2.1 Tracheostomy tubes, including the neck-plate, should have smooth external and internal surfaces The cuff should have a smooth surface C.2.2 The patient end of the tracheostomy tube should be free from sharp edges C.2.3 neck The neck-plate should be rounded at the edges, and its shape should adapt to the contour of the patient's C.2.4 For tracheostomy tubes with an adjustable neck-plate, use of the mechanism for securing the neck-plate should not cause a significant reduction of the inside diameter of the tube C.2.5 A retaining or latching device can be incorporated in the design to provide added security of attachment of the conical connectors Such a device can, however, introduce other hazards such as accidental extubation It should, therefore, be as light and compact as possible Any projections (for example hooks, lugs or studs) should be designed so as to minimize the risk of catching on surgical dressings or other equipment 17 Licensed Copy: athen reading, Reading University Library, 31/01/2010 05:17, Uncontrolled Copy, (c) BSI BS EN 1282-2:2005+A1:2009 EN 1282-2:2005+A1:2009 (E)
