A tracheal tube is a catheter that is inserted into the trachea for the primary purpose of establishing and maintaining a patent airway and to ensure the adequate exchange of oxygen and carbon dioxide. Many different types of tracheal tubes are available, suited for different specific applications: * An endotracheal tube is a specific type of tracheal tube that is nearly always inserted through the mouth (orotracheal) or nose (nasotracheal). * A tracheostomy tube is another type of tracheal tube; this curved metal or plastic tube may be inserted into a tracheostomy stoma (following a tracheotomy) to maintain a patent lumen. * A tracheal button is a rigid plastic cannula about 1 inch in length that can be placed into the tracheostomy after removal of a tracheostomy tube to maintain patency of the lumen. ==History== Portex Medical (England and France) produced the first cuffless plastic 'Ivory' endotracheal tubes, in conjunction with Magill's design later adding a cuff as manufacturing techniques became more viable, these were glued on by hand to make the famous Blue-line tube copied by many other manufacturers. Mallinckrodt GmBH developed the disposable endotracheal tube and produced a plethora of design variations, adding the 'Murphy Eye' to their tubes in case of 'accidental' placement of the tube to avoid right bronchial occlusion. David S. Sheridan was one of the manufacturers of the American markets "disposable" plastic tracheal tube now used routinely in surgery. Previously, red rubber (Rusch-Germany) tubes were used, then sterilized for re-use.. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「tracheal tube」の詳細全文を読む スポンサード リンク
