The utility model relates to a piston type double chamber pipe joint. The inner tube of the utility model is hollow, the upper end of the inner tube is connected with a cap, the lower end of the inner tube is connected with a piston, and the piston is hollow, sliding connected with the outer tube. The middle and lower part of the outer tube is provided with an air vent, and the air vent is connected with the air duct. The utility model overcomes the defect that the existing double-lumen tube joint needs to be repeatedly disassembled and installed to change the one-lung ventilation, which causes a lot of work to the anesthesiologist, often fails to take into account the monitoring of the vital signs of the patients during the operation, and brings huge potential safety hazards. The utility model has the advantages of simple and convenient operation, simple and convenient alteration of one-lung and two-lung ventilation, no disassembly, no air leakage, avoiding a large number of cumbersome operations and simplifying procedures, so that the anesthesiologist can have more energy in the monitoring of patients'vital signs, safety, reliability, wide application range, and fully liberate the restraint of thoracotomy on the anesthetist.
【技术实现步骤摘要】
一种活塞式双腔管接头
本技术涉及一种医疗装置,特别涉及一种活塞式双腔管接头。
技术介绍
在本技术专利技术之前,围术期,特别是开胸手术,需要双腔管气管插管,萎缩一侧肺以供该肺或胸部其他脏器手术需要,而另一侧肺继续予以通气,为人体提供呼吸功能。在麻醉插管时定位双腔管、手术过程中寻找病变区域、术闭检测肺是否还有破损等整个手术进程中,频繁的予以单双肺通气的交换。现有的双腔管接头,需要反复拆卸、安装才能变更单双肺通气,给麻醉医生造成大量工作,往往无暇顾及术中患者生命体征的监测,带来巨大安全隐患。同时,术中患者通常予以恒定的挥发性吸入麻醉药镇痛镇静,反复拆卸双腔管接头,不但造成挥发性麻醉药从呼吸管道溢出污染空气,同时也破坏了患者体内药物恒定量,导致患者生命体征波动。在麻醉双腔管插管双肺定位时,现有接头往往不得不迫使麻醉医生一边忙于对一侧肺通气的掌控,变更单双肺通气频率和潮气量,处理管道漏气报警等,而又要对另一侧肺定位进行操作,一心多用,手忙脚乱,很容易出错,埋下巨大安全隐患。
技术实现思路
本技术的目的就是要克服上述缺陷,研制一种活塞式双腔管接头。本技术的技术方案:一种活塞式双腔管接头,其主要技术特征在于,内管呈中空状,内管上端部连接盖帽,内管下端连接活塞,活塞呈中空状,与外管滑动连接,外管中下部设置通气口,通气口连通通气管道。所述外管的上端设置有上卡口,外管的下端设置有下卡口,活塞在外管的上卡口、下卡口之间。所述活塞由内管卡槽和活塞橡胶体构成,内管卡槽连接内管下端,活塞橡胶体内侧设置有螺纹凸起,中间连接内管卡槽,外侧滑动连接外管内壁。所述内管下端通过内管卡槽连接活塞。本技术 ...
