15、chines; it makes provision for tracheal tubes of the Cole type, i.e.the type with a small patient end for use with infants. The narrowest part of the infant airway is the non-distensible cricoid cartilage ring which is the main controlling factor during tracheal intubation. Consequently, the size of

16、 the tracheal portion is the limiting factor which determines the choice of size of tube to be used. Provision is made for a large number of sizes of tubes at close intervals so that the laryngo-tracheal portion of the Cole tube may easily fit the cricoid ring without causing trauma or undue resista

17、nce to gas flow. WARNING NOTE Users are cautioned that in clinical practice the shoulder must not exert pressure on the laryngeal tissues. The larger lumen in the oral portion of the Cole type is provided mainly to enable the use of a tracheal tube connector of larger size than would otherwise be po

18、ssible, to minimize resistance to gaseous flow and to facilitate the introduction of a suction catheter. 1 Scope and field of application This part of ISO5361 specifies general requirements for Cole tubes for use in infants. 2 Reference ISO 5361-1, Tracheal tubes Part 1: General requirements. 3 Defi

19、nitions For the purposes of this part of ISO5361, the definitions given in ISO5361-1 and the following definitions apply. 3.1 Cole tube specialized tracheal tube combining a short laryngo-tracheal portion of a small diameter and a longer oral portion of larger diameter with transition from one to th

20、e other resulting in a shoulder 3.2 laryngo-tracheal portion that portion of a Cole tube of small diameter extending from the bevel tip to the point at which there is an increase in the outside diameter 3.3 oral portion that portion of a Cole tube of a larger diameter extending from the machine end

21、to the point at which there is a decrease in the outside diameter 3.4 shoulder that portion of a Cole tube at which transition from the oral portion to the laryngo-tracheal portion occurs 4 General Cole tubes shall, unless otherwise specified, comply with the general requirements for tracheal tubes

22、specified in ISO5361-1. 5 Size designation The size of Cole tubes shall be designated by the nominal inside diameter of the tracheal portion of the tube, d 1(see the Figure), expressed in millimetres. 6 Size range The size range of Cole tubes shall be in accordance with the table. 7 Dimensions 7.1 T

23、he dimensions of Cole tubes shall be in accordance with the table and the figure. 7.2 The inside diameter (ID) shall be the nominal diameter subject to a tolerance ofmm. 8 Bevel 8.1 Cole tubes shall have a bevel of45 5 in relation to the axis of the tube. 8.2 The end of the tube at the bevel shall b

24、e rounded and the orifice(s) shall be free from sharp edges. 8.3 The bevel shall have the opening facing to the left when the tube is viewed towards the concave aspect from the machine end. 9 Shoulder 9.1 There shall be smooth transitional blending at the inside and outside surfaces between the trac

25、heal and oral portions of the tube. 9.2 The combination of the inside and outside profiles shall be such as to minimize kinking in the region of the shoulder. 9.3 The axial length of the outside surface of the shouldered region, S 1 S 2(see the Figure), shall not exceed4mm for sizes up to and includ

The curvature shall start within20mm of the beginning of the taper (see S 1

27、in the Figure) on the outside surface. 11 Marking 11.1 In addition to the general requirements for marking given in ISO5361-1, Cole tubes shall be marked with the size, in accordance with clause5 and the table, together with the maximum outside diameter of the tracheal portion (OD; seetheFigure), in

28、 millimetres, and designated as shown in the following examples: TRACHEAL END ID 3,5/5,0 OD or ID 3,5/5,0 OD 11.2 The marking of the size of the Cole tube shall be situated on the bevelled side of the oral portion within the minimum length of the tube reading from the patient end to the machine end
