The utility model provides an improved three-chamber two-bag tube, which comprises a main pipe and a three-chamber tube at the end of the main pipe. The main pipe is a highly elastic one, including the esophageal airbag segment, the gastric airbag segment, the esophageal airbag segment and the gastric airbag segment. The compressed airbag is arranged in the cavity of both the esophageal airbag segment and the gastric airbag segment, and is inflated, the airbag and the smooth tube body expands. The three-chamber two-bag tube adopts the structure of the built-in esophageal airbag and the gastric airbag. In air, the main pipe body extends smoothly from the end of the three-chamber tube without bulge. Compared with the traditional convex three-chamber two-sac tube, the three-chamber two-sac tube reduces the difficulty of intubation, alleviates the pharyngeal reaction during intubation, and makes patients more acceptable. Once inflated, the balloon in the esophageal airsac segment expands in a column-shaped way, and the balloon in the gastric airsac segment expands in a cystic-shaped way. In addition, after deflation, the balloon expands in a high-bomb Under the elastic resilience of the sexual supervisor, the balloon is compressed again to reduce the risk of iatrogenic rebleeding during extubation.

改良型三腔二囊管
本技术涉及改良型三腔二囊管。
技术介绍
三腔二囊管压迫止血一直是治疗食管静脉曲张等出血的首选方法,具有经济、方便、操作简单的优点,一般用于止血药物无效时的临时应急措施,为进一步的救治争取时间。现有的三腔二囊管一般包括三腔管、食道气囊和胃气囊,其中三腔管包括胃管、食道气囊管和胃气囊管,胃管、食道气囊管和胃气囊管延伸出硬质管,食道气囊管延伸的硬质管与食道气囊连接,胃气囊管延伸出的硬质管与胃气囊连接,市场上的三腔二囊管中食道气囊及胃气囊普遍为外凸型结构,插管时易引起患者的咽反应,提高了插管的难度,另外在长时间治疗后,气囊与胃壁粘附,拔管时存在医源性出血的风险,需要改进。同时,目前市场上的三腔二囊管充气端密闭性相对较差,临床上一般需再备用止血钳夹闭后才更安全,避免漏气,临床操作不便,故需改进。
技术实现思路
有鉴于此,本技术的目的是提供改良型三腔二囊管,减轻咽反应,降低医源性出血风险。为解决上述技术问题,本技术的技术方案是:改良型三腔二囊管,包括主管道及主管道端部的三腔管,所述主管道为高弹性管道,包括食道气囊段、胃气囊段,食道气囊段及胃气囊段腔内均设压缩态气囊,经充气,食道气囊段内气囊及平滑管身膨胀呈柱状,胃气囊段内气囊及平滑管身膨胀成囊状。本三腔二囊管采用内置食道气囊、胃气囊的结构,未充气时,主管道管身自端部三腔管以后平滑延伸,无凸起,相比传统外凸型三腔二囊管,本三腔二囊管降低了插管的难度,减轻了插管时的咽反应,使患者更容易接受;一经充气,食道气囊段的气囊及主管道管身膨胀呈柱型,胃气囊段内的气囊及主管道管身膨胀呈囊型,另外,放气后,在高弹性主管身弹性恢 ...
