Description

内建影像内视镜的全时影像监控的气管内管 技术领域
本发明关于一种气管内管，尤指一种可以运用于例行及困难气管内管插管，内建影像内视镜，全时影像监控的气管内管，可用以全时监控气管内管的位置、气管内结构及各种状况。
背景技术
气管内管插管(Endotracheal Intubation)用于呼吸道处理(airway management)，建立确定呼吸道(definite airway)情况，为第一线急诊、外伤、重症医疗领域重要的急救措施。病人可能因为肺炎或是急性肺水肿引起呼吸衰竭、脑中风或是低血糖引起意识昏迷、颜面外伤危及呼吸道、甚至急性扁桃腺炎或是异物哽塞引起上呼道阻塞都需要第一线医疗人员紧急介入，以维持病人的给氧及通气(oxygenation and ventilation)，避免缺氧造成不可逆的并发症。
气管内管插管是将一气管内管(Endotracheal tube)插入病人的气管内，并接上一呼吸器，以使呼吸器将氧气送至病人的气管内，确保病人的呼吸道畅通、防止异物吸入肺部，进而确保病人有足够的通气量。
发明概述
技术问题
然而，进行气管内管插管作业时，操作人员必须确保气管内管正确插入气管内，且避免将气管内管插入一线之隔、邻近的食道。而目前医疗上确保气管内管正确插管位置及深浅的方法，包括以听诊器听、检视气管内管壁是否有进出的雾气(fogging)、插管后拍摄X光、及潮气末二氧化碳(EtCO2)监测器；EtCo2是通过一设于气管内管及呼吸器之间的二氧化碳侦测器，若病人的吐气含有很高的二氧化碳浓度，即可确定气管内管的位置正确，是位于气管内，但此种方式仍有运用上的缺陷，二氧化碳侦测器容易被病人的痰或分泌物堵住而影响判读，且病人在行进中移动或是晃动，例如：救护车上或被送出加护病房去做检查时，容易造成其侦测不准、误差或是误判等情况发生；此外，整体二氧化碳侦测 器非常笨重，容易有将气管内管扯动拔出的风险。
因此对应此种缺陷，医界需要发展出另一种方法，更有效、更稳定的侦测及确定气管内管位置。传统光学通条(optical-stylet)气管内管插管以一末端(病人端)具有摄影镜头的光学通条组装放入气管内管中央通道内，连同气管内管一起插入病人的气管中，若此时通过摄影镜头连接的显示器，可看到病人左右支气管内的分岔处(气管内隆突，英文名carina)，气管内管的插管位置即正确；之后必须将光学通条拔出，才可将气管内管接上呼吸器。
气管内管插管当时，可以看到气管内隆突(carina)，确定气管内管的正确位置，且之后以各种方式辅助以确定气管内管的插管位置，例如听诊、气管内管壁雾气(fogging)、插管后拍摄X光、及潮气末二氧化碳(EtCO2)监测器；但之后病人移动、活动、翻身、咳痰都有可能改变气管内管位置；病人自急诊收住院到加护病房、自加护病房转出做各种检查、急诊及重症病人院际转院、插管病人咳嗽抽痰、开刀房麻醉中病人翻身以进行手术都有气管内管滑脱跑位的风险，且发生时往往造成延迟发现及处理的呼吸道处理悲剧。
问题的解决方案

在其中一项实施例中，所述光学通条由各副通道的后端开口穿出且摄影装置朝向不同方向撷取影像。
在其中一项实施例中，管状本体的侧缘开设有一气口，气口邻近后端，气口连通主通道。
在其中一项实施例中，气口的口径等于主通道的内径，或是气口的口径小于主通道的内径且大于副通道的管径。
在其中一项实施例中，管状本体的径向剖面概呈椭圆形，主通道的径向剖面概呈椭圆形。
在其中一项实施例中，摄影装置远端连接显示器。
通过上述技术方案，本发明可达成功效，呼吸器的氧气及光学通条可分别由主通道及副通道进入管状本体，因此，在气管内管插管过程中，光学通条伸出管状本体最前端作为导引，并通过其末端的摄影装置及摄影装置连接的显示器，操作人员即可全时连续地监控气管内管的插管过程，在最前端辨别及找寻声门(glottis)-气管内的入口；同时有别于传统的光学通条气管内管插管，内建式的光学通条在完成气管内管插管后拔回内缩与管状本体末端平行，此时做为后续全时监控气管内(trachea)内部状况、出血或是咳痰，以及气管内管(endotracheal tube)位置的全时监视器；相对于传统光学通条在气管内管插管后必需拔除，仅能短暂的监视气管内状况，本发明则有任何出血咳痰或位置改变，可以监控并予以 及时处理的优点。
并且，病人在气管内管插管之后，在急诊及加护病房，不需照射胸部X光，通过本发明即可全时影像监控气管内管的位置及其与气管内隆突(carina)相对的距离，以随时调整气管内管的深度及位置，避免其自病人的气管内滑脱或是滑落误入食道，通过本发明可免除以往因照射胸部X光所耗费的人力、时间及医护人员暴露于辐射线的机率，且大幅提升病人安全。
此外，使用者能够以传统使用光学通条的技术，将光学通条分别由主通道及副通道进入管状本体，以进入主通道的光学通条伸出管状本体的后端，作为主要导引探索气管内及寻找声门的作业，这是传统的光学通条气管内管插管作业(Optical Stylet Intubation)，位于副通道的光学通条，则全时连续地监控气管内管的插管过程；借此，本发明能够结合使用及维持传统光学通条气管内管插管的技术，使初次使用者能立即使用，再加上辅助的副通道光学通条影像监测，以达成及创造出更安全更有效率的多角度广视野影像监测插管技术。

实施该发明的最佳实施例
本发明的最佳实施方式
下面结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是本发明还可以采用其他不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似推广，因此本发明不受下面公开的具体实施例的限制。
请参阅图1至图9所示，本发明提供一种内建影像内视镜的全时影像监控的气管内管，其包括：
一管状本体10，其具有可挠性且有预型的曲度，管状本体10的径向剖面概呈椭圆形，如图3所示；管状本体10用以放置于病人1的气管内2内。管状本体10具有相反设置的一前端11及一后端12，前端11连接呼吸器，邻近于后端12设有一充气囊13，其中，管状本体10的后端12为斜口状或平口状，在本发明第一实施例中，管状本体10的后端12为斜口状，管状本体10的后端12的倾斜角度θ为大于0度且小于90度，其中，请参阅图4所示，后端12的倾斜角度θ为35度；请参阅图6所示，后端12的倾斜角度θ为50度；当倾斜角度θ角度越大，表示后端12的倾斜面越大，因此，当管状本体10放入病人1的气管内2过程中，后端12与气道的突出特征(例如：声带和鼻甲)接触时，通过可挠性的管状本体10及斜口的后端12能更加滑顺且轻柔弯曲地绕过突出特征，能有效避免突出特征创伤；在本发明第二实施例中，管状本体10的后端12为平口状，如图9所示。
并且，管状本体10穿设一主通道14，主通道14贯穿管状本体10的前端11及后端12，使呼吸器将氧气由主通道14送至病人1的气管内2，主通道14的径向剖面概呈椭圆形，如图3所示。
管状本体10还穿设一副通道15，副通道15设于主通道14的一侧，并具有相互连通的一前端开口151及一后端开口152，前端开口151位于管状本体10的侧缘，后端开口152开设于后端12；当管状本体10放置于病人1的气管内2时，前端开口151高于病人1的口咬部位3，且外露于口咬部位3之前，在口咬合部位外露且可见；其中，副通道15的数量为多个，各副通道1514等角度设置；在本发明实施例中，如图3所示，所述副通道15的数量为2个，两个副通道15间隔180度。
此外，管状本体10的侧缘开设有一气口16(Murph Eye)，气口16邻近后端12，气口16连通主通道14，其中，气口16的口径等于主通道14的内径，或是气口16的口径小于主通道14的内径且大于副通道15的管径，在本发明实施例中，气口16的口径为主通道14内径的四分之三。
一光学通条20，其长度大于管状本体10且具有可挠性，光学通条20的弯曲度能符合管状本体10的弯曲度；光学通条20穿贯设于副通道15的前端开口151及后端 开口152，光学通条20的末端21位于后端开口152时，光学通条20自前端开口151穿出的部分具有一量测刻度22，在本发明实施例中，光学通条20的数量配合所述副通道15的数量，每一副通道15穿设有一条光学通条20。
所述光学通条20的末端21设有一摄影装置23，摄影装置23所述光学通条20的末端21由后端开口152穿出，通过摄影装置23撷取病人1的气管内2影像，而每一光学通条20由各副通道15的后端开口152穿出且摄影装置23朝向不同方向撷取影像，请参阅图5及图7所示，两光学通条20的摄影装置23分别往方向a及方向b撷取影像；借此，能够使影像互补及部分重叠，以多角度及增广视野辅助寻找及定位声门(glottis)，帮助迅速及有效的进行气管内2插管。
并且，摄影装置23耦接显示器，显示器可为目镜或远端萤幕，显示器能够有线或无线与摄影装置23连接，当显示器为目镜时，显示器设于光学通条20异于摄影装置23的一端，以有线连接的方式连接于摄影装置23；当显示器为远端屏幕时，则以无线连接的方式与摄影装置23远端连接。
请参阅图8所示，操作人员将光学通条20通过副通道15自管状本体10的后端12穿出后作为导引，寻找及定位声门(glottis)，先将光学通条20放入于病人1的气管内2内，此时，光学通条20末端21的摄影装置23即可撷取气管内2的影像，而操作人员通过显示器看到病人1的气管内隆突4(carina)，确认光学通条20是位于病人1的气管内2内后，即可再将管状本体10沿着光学通条20放入于病人1的气管内2内，此种方法称为railroad轨道导入，以确保管状本体10的插管位置；此时将做为导引的光学通条20拉出回收，使光学通条20的末端21与管状本体10平行，或是稍微内缩内收，之后就做为全时监控的光学通条20。
然后，通过光学通条20的量测刻度22，即可随时查看光学通条20伸出及内缩内收的长度；而病人1的口咬部位3将管状本体10咬住后，便完成管状本体10插入气管内2的程序；接着，操作人员可将管状本体10接上呼吸器，以使呼吸器将氧气由主通道14送至病人1的气管内2。
本发明的副通道15设于管状本体10的左右侧，操作人员能够依照惯用手习惯，将主要操控的光学通条20穿入对应惯用手的所述副通道15中，其它副通道15所穿设的光学通条20则为辅助增加摄影视野所用，以多视角及增广视野辅助寻找 及定位声门(glottis)，帮助迅速及有效气管内2插管；如图5所示，两光学通条20的摄影装置23分别往方向a及方向b撷取影像。
借此，由于呼吸器的氧气及光学通条20可分别由主通道14及副通道15进入管状本体10，因此，在整个气管内2的插管过程中，光学通条20不需拔出，操作人员通过其末端21的摄影装置23及显示器，能够全时连续地监控插管过程，以达到全时监控气管内管的位置的功能，可有效防止插管位置滑落及错误的情形发生。
在气管内2插管过程中，光学通条20伸出管状本体10的后端12约八至十厘米做为导引，通过光学通条20的末端21的摄影装置23及摄影装置23连接的显示器，操作人员即可全时连续地监控气管内管的插管(endotracheal intubation)过程，在管状本体10的后端12辨别及找寻声门(glottis)气管内2的入口；同时有别于传统的通条气管内管插管，本发明光学通条20在完成气管内2插管后，拔回内缩与管状本体10的后端12平行，此时做为后续全时监控气管内2(trachea)内部状况、出血或是咳痰，以及气管内管(endotracheal tube)位置的全时监视器；相对于传统通条在气管内2插管后必需拔除，仅能短暂的监视气管内2内状况，本发明则有任何出血咳痰、位置改变，可以监控并予以及时处理的优点。
并且，病人1在插管之后，在急诊或加护病房，不需照射胸部X光以确定气管内2内管位置，通过光学通条20的摄影装置23及显示器，即可全时影像监控管状本体10的位置及其后端12与气管内隆突4(carina)的距离，以随时调整管状本体10的深度及位置，避免其自病人1的气管内2滑脱或是滑落误入食道；因此，通过本发明可免除以往因照射胸部X光所耗费的人力、时间及医护人员暴露于辐射线的机率，大幅增加病人1安全。
此外，管状本体10的径向剖面概呈椭圆形，能够配合病人1的嘴型，使病人1无须过于张大嘴巴便能轻易咬合管状本体10，借以提供病人1咬合的舒适性。
另外，使用者能够以传统使用光学通条20的技术，将光学通条20分别由主通道14及副通道15进入管状本体10，以进入主通道14的光学通条20伸出管状本体10的后端12，作为主要导引探索气管内2及寻找声门的作业，这是传统光学通条20的气管内管插管作业(Optical Stylet Intubation)，而位于副通道15的光学通条20， 则全时连续地监控气管内管的插管过程；借此，本发明能够结合使用及维持传统光学通条20气管内管插管的技术，使初次使用者能立即使用，再加上辅助的副通道15的光学通条20影像监测，以达成及创造出更安全更有效率的多角度广视野影像监测插管技术。
以上说明内容仅为本发明较佳实施例，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
