The invention relates to a department of respiration medical device, in particular to a lower respiratory tract obstruction cavity expansion device, comprising a guide tube, proximal expansion tube, distal expansion tube and two section type hoist balloon, the two type hoist includes proximal and distal balloon balloon balloon, the proximal end of the expansion pipe and the distal extension tube is connected and fixed on the guide tube on both sides, including the expansion of the proximal end of pipe extends to the proximal and distal balloon dilatation tube extends to the distal balloon. The proximal and distal end of the saccule is blind. The side wall of the proximal and distal saccule is provided with a plurality of elliptical air outlets. The invention has the advantages of simple structure, convenient use, piecewise control through the balloon, the traditional tube type gas outlet is closed with improved side wall outlet of the uniform microporous operating equipment, makes the obstruction of lower respiratory tract of the trachea and bronchi were range to control the expansion of more accurate and precise.

一种下呼吸道腔道阻塞扩张设备
本专利技术涉及一种呼吸科医疗器械,特别涉及一种下呼吸道腔道阻塞扩张设备。
技术介绍
临床上通常把气管、主支气管及肺内的各级支气管,合称为下呼吸道(lowrespiratorytract)。在吸气时,空气通过鼻子或者口腔进入气管,而气管则进而分叉形成两个支气管,并且进入胸腔内的肺组织中。介入治疗是在70年代后期发展起来的,它是在影像医学(X射线、超声、CT、MRI等)引导下,通过经皮穿刺途径或通过人体原有孔道,将介入导管或器械输送至病变部位进行诊断造影,治疗或组织采集。气管狭窄和异物堵塞是呼吸系统常见症状,严重时会危机生命安全,吕前临床应用中还没有一种专用的器械。中国专利公开了一种气管扩张器(专利号200620085891.6),包括外套管和贯通外套管内的钢丝绳,以及连接在钢丝绳两端的扩张钢丝网和拉杆。它是通过推动拉杆推动钢丝绳下行,此时钢丝绳前端的的扩张钢丝从外套管中推出,从而实现扩张病人气管的作用。其缺路是外套管为硬性管,不易穿插于气管内,此外扩张钢丝的扩张口径吕定,难以满足实际应用。下呼吸道扩张术是通过气管、支气管将球囊扩张导管擂 ...
