The utility model discloses a tracheal intubation tube with a plurality of drainage pipes. The tracheal intubation tube includes a main intubation body and an air bag. The air bag ring is located near the peripheral part of the main intubation body near the front end. The air bag inflatable pipe of the main intubation body has an inflatable passage, and there are at least two drainage pipes in the wall of the main intubation body. The suction holes of the drainage pipe are dispersed in the air bag. The peripheral part of the tube wall of the intubation body at the back end. At least two drainage pipes are arranged in the wall of the main body of the intubation. When draining, one of the drainage pipes can be injected with water, and the other can drain with liquid, so as to realize continuous negative pressure drainage. In addition, the suction holes of the drainage tube are dispersed and can still be applied after the patient needs to change his position due to treatment. It can reduce the accretion fluid and VAP caused by the change of patient's position, reduce the replacement rate of endotracheal intubation, reduce the risk of medical malpractice of endotracheal intubation, and reduce the medical expenses and the workload of medical staff.
【技术实现步骤摘要】
一种具有多个排液管的气管插管
本技术涉及医疗器械领域,特别是涉及一种具有多个排液管的气管插管。
技术介绍
俯卧位机械通气(pronepositionventilation,PPV)在急危重患者的应用越来越广泛,特别是对ARDS患者的治疗效果显著。有研究显示,PPV能通过体位改变,增加ARDS背侧肺组织的通气,改善肺泡通气/血流比、分流和氧合。一个多中心随机对照试验研究证实俯卧位通气能显著改善中重度ARDS患者的病死率。但PPV通气治疗过程中由于病人体位的变化,即由仰卧时变换为俯卧位,导致气囊上滞留物由常置的气管插管背部变换到气囊上气管插管前端。有研究显示,气囊上滞留物是呼吸机相关肺炎(ventilatorassociatedpneumonia,VAP)病原的重要来源。因此,必须及时有效的清除气囊上滞留物,预防误吸和VAP。
技术实现思路
