气管插管在危重病人的抢救、复苏治疗以及临床麻醉中起着至关重要的作用，但往往由于病人病情较重，气道暴露不充分，痰液阻塞异物存留等诸多因素，给插管带来了一定的困难。在临床工作中，我们研制出气管导管带光源吸引导引器，为快速准确顺利地完成气管插管提供了较好的条件 Tracheal intubation plays a crucial role in the rescue, resuscitation and clinical anaesthesia of critically ill patients, but it is often due to a large number of factors such as the patient’s severe illness, inadequate airway exposure, and foreign body obstruction and foreign body retention. Some difficulty came. In clinical work, we have developed a tracheal catheter with a light source to attract the guide, which provides a good condition for the rapid and accurate completion of tracheal intubation
