本实用新型涉及一种气管插管，特别是涉及一种可视化泄气式支气管封堵型气管插管，属于医疗器具技术领域。
背景技术
目前，微创技术快速发展，越来越多的胸腔手术需要单侧肺通气，单肺通气通常采用双腔支气管导管进行隔离，双腔气管插管因管径较粗，特别是对于婴幼儿来说，由于其呼吸的气管较细，不能插入较粗的插管，因而操作难度大，容易造成呼吸道并发症。现有技术中存在单腔三囊支气管插管，这种单腔三囊支气管插管既要实现双向通气，又要实现单向通气，除了各有一个气管套囊和一个支气管套囊，在支气管腔内增加一个气囊，用于封堵支气管内腔实现单向通气。目前这种插管内径通常都大于6.5mm，小于6.5mm，管内无法装入气囊，也就无法生产，最终导致婴幼儿患者无管可用。还有一种单腔双气囊支气管插管，气管套囊与支气管套囊之间的气管导管一侧设有一个气管导管侧孔，支气管套囊内的支气管导管上设有支气管导管侧孔，支气管导管侧孔上设有弹性膜，弹性膜在支气管套囊充气的情况下可向内凹陷紧贴支气管导管的内壁，从而对支气管导管内外封堵支气管，但现有产品不能对支气管导管腔彻底封堵的，无法满足临床需要。
申请人日前申请的一种支气管封堵型气管插管，实践过程中发现，当使用时虽然实现了成人和儿童胸腔手术中隔离肺所需的单肺通气，易于生产制造，临床操作简单容易、并发症少，而且能满足不同年龄段患者单肺通气需求。但是所封堵侧的肺内部残留的气体无法排除，影响手术操作；且封堵侧 的肺内分泌物及手术失血无法清除。因此需要进一步改进。

如图1和图7所示，一种可视化泄气式支气管封堵型气管插管，所述气管插管包括气管导管1，所述气管导管1一端连接有导管接头2，气管导管1管身连接有气管套囊3，所述气管套囊3与所述气管导管1末端之间的气管导管1管身至少设有两个气管导管侧孔4；所述支气管导管7管身连接有支气管导管封堵套囊5，所述气管插管还包括吸引管6；所述气管导管1末端向外延伸并逐渐收缩形成连通所述吸引管6的支气管导管7，气管导管1管壁内设有视频导线16，所述视频导线16一端在气管导管的导管接头2端延伸出来并连接有数据接口19，视频导线16另外一端连接有LED灯17和微型摄像头18，所述LED灯17和微型摄像头18位于气管导管末端的气管导管侧孔4处；所述支气管导管封堵套囊5远端的支气管导管7前端及侧壁设有吸引孔8，所述吸引孔8连通所述吸引管6；所述吸引管6近端连接有吸引接头9，吸引管6侧部连接有泄气阀10。
可视化泄气式支气管封堵型气管插管的一个实施例中，所述气管套囊3连接有第一充气管11，所述第一充气管11上设有第一充气组件12；所述支气管导管封堵套囊5连接有第二充气管13，所述第二充气管13上设有第二充气组14件；所述充气组件包括依次连接的阀体和压力显示球。第一充气组件12通过第一充气管11为气管套囊3充气，第二充气组14件通过第二充气管13为支气管导管封堵套囊5充气。充气组件属于现有技术。
参见图4，可视化泄气式支气管封堵型气管插管的一个实施例中，所述吸引管6与所述第一充气管11、第二充气管13分别穿过所述气管导管1的 管壁，吸引管6、第一充气管11和第二充气管13之间相邻或相对设置；所述吸引管6的朝向与所述支气管导管7朝向相同。吸引管6、第一充气管11和第二充气管13分布在气管导管1的管壁中，实现吸引管6、第一充气管11和第二充气管13的合理布局。同时直接通过吸引管6的朝向判断支气管导管7朝向，无需增加支气管导管7朝向标识。
参见图5和图6，可视化泄气式支气管封堵型气管插管的一个实施例中，所述第一充气管11、第二充气管13分别穿过所述气管导管1的管壁，所述吸引管6设置在所述气管导管1的管壁内侧，吸引管6与气管导管1的管壁连接；所述吸引管6的朝向与所述支气管导管7朝向相同。吸引管6也可以分布在气管导管1的管壁内侧，实现吸引管6、第一充气管11和第二充气管13的合理布局。吸引管6可以根据需要设计为圆形或椭圆形，同时直接通过吸引管6的朝向判断支气管导管7朝向，无需增加支气管导管7朝向标识。
需要进一步说明的是，本实用新型中的吸引管6、第一充气管11和第二充气管13三者中，第一充气管11和第二充气管13可以更靠近导管接头2的一端，而吸引管6位于第一充气管11和第二充气管13下方的区域，同时也可以设计为吸引管6更靠近导管接头2的一端，而第一充气管11和第二充气管13位于吸引管6下方的区域。
可视化泄气式支气管封堵型气管插管的一个实施例中，所述气管导管1管身设有气管导管刻度标识和支气管导管刻度标识，所述气管导管刻度标识的刻度开始于远端的气管导管侧孔4，所述支气管导管刻度标识的刻度开始于支气管导管7远端。通过气管导管刻度标识，可以知道远端的气管导管1孔在气管内所处的位置；通过支气管导管刻度标识，可以知道支气管导管7末端到门齿的距离。
可视化泄气式支气管封堵型气管插管的一个实施例中，所述气管导管1管身设有管号孔径标识，所述管号孔径标识位于所述气管导管1管身近端。 可以满足不同年龄段的患者使用需求。
可视化泄气式支气管封堵型气管插管的一个实施例中，所述气管导管1内径为3.0-10.0mm；所述气管导管侧孔4呈圆形、椭圆形或n边形，n为大于等于3的整数，侧孔的边沿呈直线或曲线。
可视化泄气式支气管封堵型气管插管的一个实施例中，所述气管导管1呈直管状，所述气管导管1与所述支气管导管7之间设有20°-50°折角,气管导管1与支气管导管7平滑过渡连接。
参见图2，可视化泄气式支气管封堵型气管插管的一个实施例中，当所述气管插管的管号为5.0及以下时，气管插管采用无气管套囊3或有气管套囊3结构；当所述气管插管的管号为5.0以上时，气管插管采用有气管套囊3结构。由于6岁以下小儿气道最狭窄处不是声门，而是声门下方的环状软骨，因此本实用新型的气管套囊3位置上移，其上缘位于环状软骨稍下。小儿气管插管的管号计算方式为：导管号码(导管内径mm)＝年龄/4+4.0，当本实用新型用于新生儿及婴幼儿(0-3岁)的气管插管，即导管号码为5.0及以下时，可以采用无气管套囊3设计,当然也可以通过改变气管套囊3的尺寸,采用有气管套囊3的结构。
参见图3，可视化泄气式支气管封堵型气管插管的一个实施例中，所述气管插管的管壁设有加强钢丝15或无加强钢丝15。加强钢丝15起到增加气管插管管壁结构强度，可以根据需要设计有加强钢丝15或无加强钢丝15两种款式。
可视化泄气式支气管封堵型气管插管的一个实施例中，所述微型摄像头18的镜头倾斜角度为0-90°。采用有角度的斜镜头方便通过微型摄像头18观察前方。
参见图7和图8，可视化泄气式支气管封堵型气管插管的一个实施例中，所述微型摄像头18外围设有n个所述LED灯17，n为正整数，若干LED灯 呈弧形或圆形分布在微型摄像头18的外围。LED灯为微型摄像头提供照明，微型摄像头属于现有技术。
可视化泄气式支气管封堵型气管插管的一个实施例中，所述视频导线16通过数据接口19连接有显示器，所述显示器用于通过所述微型摄像头18获取气管内影像。
本实用新型的气管插管还包括吸引管6；气管导管1末端向外延伸并逐渐收缩形成连通吸引管6的支气管导管7；支气管导管7末端设有吸引孔8，吸引孔8连通吸引管6；吸引管6前端连接有吸引接头9，吸引管6侧部连接有泄气阀10。本实用新型适用于胸腔手术中的单侧肺通气，以设有气管套囊3和支气管导管封堵套囊5的插管为例，使用时，可视化支气管封堵型气管插管的吸引接头9连接中心负压吸引，用可视喉镜依次显露舌根、会厌、声门，将气管插管送入的同时把分泌物及痰液吸出来。支气管导管7与气管导管1之间设有20°-50°折角更容易进入声门,首先将气管插管的支气管导管7经声门插入气管，拔出插管芯，又因为气管导管1与支气管导管7平滑过渡连接，因此气管导管1便很容易顺势送入人体气管。将视频导线的数据接口19连接显示器，在可视状态下将支气管导管7插入需要封堵侧的人体支气管中，通过显示器屏目定位支气管导管封堵套囊5，术中持续监测支气管导管封堵套囊5的位置是否正确，并根据需要调整位置。
本实用新型使气管套囊3位置上移，其上缘位于环状软骨稍下位置，一方面可以保证气管套囊3以下可以开足够的孔用来通气，另一方面有效的防止返流进入肺部引发感染。术中单肺通气时气体通过气管导管1以及气管导管侧孔4进入另外一侧的肺，术侧肺则实现封堵的同时，通过吸引孔8、吸引管6和吸引接头9将封堵侧肺内残留的气体排出，从而确保人体有效供氧和手术的成功进行。本实用新型的可视化功能克服了双腔管和封堵器置入和定位困难的问题，持续可视更避免了术中意外插管移位、错位等不良事件， 不仅能够用于成人和儿童胸腔手术中隔离肺所需的单肺通气，易于生产制造，临床操作简单容易、并发症少，而且能满足不同年龄段患者单肺通气需求。同时使用过程中还能实现封堵侧肺内残留气体的排出，分泌物及出血的吸引，塌陷肺纯氧吹入，保证患者氧合，使手术操作顺利进行。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。因此，本实用新型专利的保护范围应以所附权利要求为准。
