摘　　要：目的介绍一种用于气管插管患者的气道测温装置。方法在传统气管导管的套囊内装配温度传感探头,制作成可测温的气管导管,即使在套囊破裂的情况下温度传感探头也不会脱落至气道成为异物。在保证通气功能不受影响的同时,可以使用此装置连续监测气道温度。结果经过临床初步应用证实,可测温气管导管可以便捷、准确及稳定地监测气道温度。气道温度与食道温度呈高度正相关,可准确显示人体体温变化。结论该装置可用于临床科室需气管插管(如全身麻醉)患者的体温监测,提高了临床诊治的安全性,减轻了医护人员的劳动负担。Objective To introduce a tracheal temperature monitor system.Methods By means of the temperature sensor probe placed in the cuff-ballon of the traditional endotracheal tube,a temperature measuring endotracheal tube was composed.Even after the cuff-ballon was disruptived,the temperature sensor probe would not fall off into the trachea as a corpus alienum.Without the ventilation function susceptible,the tracheal temperature could be continuously monitored.Results Through the clinical initial verification,the self-designed temperature measuring endotracheal tube could monitor the tracheal temperature conveniently,accurately and stably.A highly positive correlation was found between tracheal temperature and esophagus temperature.And the human temperature variation was manifested accurately in tracheal.Conclusion The temperature measuring endotracheal tube could be refered to the patients who required tracheal intubation（for example： general anaesthesia）,which could improve the security of the clinical diagnose and cure,and also ease the labor burden of clinical staff.
