The utility model discloses a double-lumen bronchial occluder, which consists of a double-lumen bronchial occlusion catheter channel and a multi-channel joint occlusion catheter channel. The multi-channel joint occlusion catheter channel is installed at one end of the dual-lumen bronchial occlusion catheter channel. The double-lumen bronchial occlusion catheter channel has two channels, the main channel and the secondary channel, and the main channel is normal ventilation. The accessory channel is located in the main channel, and both ends of the accessory channel are located outside the main channel. One end of the accessory channel is connected with a bronchial occlusion tube. Since the utility model has two lumens, the lumens of the bronchial occluder can be separated from the ventilated single-lumen trachea, thus avoiding the interference between the occluder and the fiberoptic bronchoscope. To the greatest extent, it ensures the stability of patients'breathing and circulation, and provides the necessary guarantee for the smooth operation and the recovery after operation.
【技术实现步骤摘要】
一种双腔支气管阻塞器
本技术涉及一种支气管阻塞器,特别涉及一种双腔支气管阻塞器,属于医疗器械
技术介绍
单肺通气主要是为了让一侧全肺萎陷,给外科手术一个良好的视野和操作空间。置入双腔支气管导管和应用支气管封堵器是临床上单肺通气最常应用的两种方法,对比两种插管方法支气管封堵器具有技术操作难度较小,导管放置和定位耗时较短,支气管、声带、咽喉等受损害的并发症较少等优点。以上优点使得支气管封堵器具有良好的应用前景。支气管阻塞器是以隔离肺为目的的一种新型产品,在肺癌、纵膈肿瘤、食道癌、胸部大动脉瘤等必须进行开胸手术时有广泛的用途。其具有1、插管简单;2、满足不同年龄段的临床需要;3、较双腔支气管插管损伤小;4、分隔双肺彻底;5、术后进入ICU无需换管;6、术中可在堵塞管直接吸痰及施行持续正压通气等多项优点而受到麻醉医生的广泛应用。一般情况下,支气管堵塞器包括拥有套囊及套囊充气管的堵塞导管和多通道接头的堵塞导管通道组成。Coopdech支气管阻塞器、CohenFlexitip支气管阻塞器以及国产维利支气管阻塞器等均是当前应用较为广泛的支气管阻塞器。目前临床中多见支气 ...
