Description

一种可转换式内置气管导管与喉罩联合通气装置
技术领域
本发明涉及医用器具，尤其涉及一种可转换式内置气管导管与喉罩联合通气装置。
背景技术
辅助呼吸通气是在进行全身麻醉手术时对手术病人进行辅助呼吸以保持病人全麻血流动力学稳定的必要手段，气管导管和喉罩等装置是辅助呼吸通气的常用辅助呼吸装置。在临床实际应用中，气管导管和喉罩等辅助呼吸装置，多为独立采用，但在手术过程中却经常需要切换不同的通气方式来实现不同的效果，由于功能设计的不同，其相互间的更换十分不便，并且在转换呼吸模式的时候往往容易造成由于麻醉早期拔管，使气道产生高敏反应导致一系列的并发症，增加了手术风险。
发明内容
本发明的目的是提供一种可转换式内置气管导管与喉罩联合通气装置，可轻松实现气管导管与喉罩间不同通气方式的切换，减少切换通气方式时产生的气道高敏反应发生的几率，提高辅助呼吸通气的可靠性和安全性。
为实现上述目的，本发明采用以下技术方案：
一种可转换式内置气管导管与喉罩联合通气装置，包括：
喉罩和气管导管，所述气管导管的前端从所述喉罩导管的远端插入所述喉罩导管中，且通过推动所述气管导管的后端，所述气管导管能够自由滑动于所述喉罩导管中；设于所述气管导管与喉罩联合通气装置上的密封锁紧装置，所述密封锁紧装置用于保持所述气管导管与喉罩联合通气装置的通气管道的气密性，并且用于锁紧所述气管导管，避免了喉罩通气方式与气管导管通气方式转换过程中出现漏气，同时密封锁紧装置能固定气管导管在喉罩导管中的位置，提高了通气方式转换后的通气有效性，解决手术中因病人不同体位或体位变动时的喉罩位移问题。
所述密封锁紧装置具有两种实施方式。
作为本发明的密封锁紧装置的第一种实施方式，所述密封锁紧装置包括：套设在气管导管的后端与喉罩导管的远端之间的可伸缩套，且气管导管的后端与喉罩导管的远端通过该可伸缩套连接并密封；以及设置在所述可伸缩套上的按压紧固装置，用于锁紧所述气管导管。按压紧固装置通过按压和掰开实现对所述气管导管的固定和释放。
作为本发明的密封锁紧装置的第二种实施方式，
所述密封锁紧装置为螺旋式密封锁紧装置。
具体地，所述螺旋式密封锁紧装置包括：套设于所述气管导管外的螺盖，其与所述喉罩导管的远端螺旋连接，该螺盖中设有按压件；套设于所述气管导管外的软体；以及，形成于所述喉罩导管远端的用于容纳所述软体的容置空间。顺时针旋转紧固螺盖时，螺盖中的按压件会下行挤压软体，使其密封所述喉罩导管和气管导管之间的空隙，保证所述气管导管与喉罩联合通气装置的通气管道的气密性。并且，顺时针旋转紧固螺盖时，螺盖中的按压件会下行挤压软体使其向中心变形，与气管导管管壁接触产生摩擦，从而实现压迫紧固，逆时针旋转紧固螺盖时，按压件上行，软体则恢复原形，软体向外回缩，不与气管导管管壁接触，使得气管导管可以滑动。
优选地，所述软体呈上窄下宽的椎状。
进一步，第二种实施方式中，还包括套设在气管导管的后端与喉罩导管的远端之间的可伸缩套，所述可伸缩套一端与所述气管导管的后端连接，另一端与所述螺盖连接。
优选地，在以上两种实施方式中，所述可伸缩套是透明可伸缩波纹管。由于所述气管导管全部被所述喉罩导管和所述可伸缩套包裹，在通气方式转换的过程中，所述气管导管不会暴露于外界，避免受到环境污染，使整个通气方式转换过程更加安全有效。
进一步，所述喉罩导管内壁设有从其近端至其远端延伸的凸纹。该可有效减少喉罩导管内壁与气管导管外壁的接触面积，防止两壁之间的粘结，同时减少气管导管在喉罩导管中滑动的摩擦力，保证通气方式转换过程的顺畅。
进一步，所述气管导管的后端向其前端延伸形成弧线，并且所述气管导管是沿着该弧线自由滑动于所述喉罩导管中。
进一步，所述气管导管是带有刻度的气管导管，所述喉罩导管上在接近其远端 的部位设置有可读取所述气管导管上的刻度的透明观察窗口。
与现有技术相比，本发明的气管导管与喉罩导管联合通气装置的有益效果如下：
1、本发明的可转换式内置式气管导管与喉罩联合通气装置可轻松实现气管导管与喉罩间不同通气方式的切换，在不同体位、或肥胖、高血压、糖尿病等病人手术中使用内置的气管导管通气模式提高辅助呼吸通气的可靠性和安全性；在病人全麻苏醒期转换为喉罩通气模式减少气管导管通气方式时产生的气道高敏反应如呛咳发生的几率，该装置可通过替代使用药物的方式减少苏醒期呛咳导致的并发症。
2、通过直接推动所述气管导管的后端在喉罩导管中移动所述气管导管，可轻松实现气管导管与喉罩导管间不同通气方式的切换，操作上十分方便；
3、由于设置了所述密封锁紧装置，保证了所述可转换式内置气管导管与喉罩联合通气装置的通气管道的气密性，避免了通气方式转换过程中出现漏气，同时密封锁紧装置能固定气管导管在喉罩导管中的位置，提高了通气方式转换后的通气有效性，解决手术中因病人不同体位或体位变动时的喉罩位移问题；
4、由于所述气管导管全部被所述喉罩导管和所述可伸缩套包裹，在通气方式转换的过程中，所述气管导管不会暴露于外界，避免受到环境污染，使整个通气方式转换过程更加安全有效；
5、由于所述喉罩导管内壁设置了从近端至远端 延伸的凸纹，从而可有效减少喉罩导管内壁与气管导管外壁的接触面积，防止两壁之间的粘结，同时减少气管导管在喉罩导管中滑动的摩擦力，保证通气方式转换过程的顺畅。
6、由于在所述喉罩导管的远端设置了透明观察窗口，故可以实时监测通气方式转换过程中气管导管的位置，配合锁紧装置可有效控制气管导管在喉罩导管中的相对位置；
通过以下的描述并结合附图，本发明将变得更加清晰，这些附图用于解释本发明的实施例。

具体实施方式
现在参考附图描述本发明的实施例，附图中类似的元件标号代表类似的元件。
实施例1
如图1所示，所述的一种可转换式内置气管导管与喉罩联合通气装置包括喉罩导管1、气管导管2、可伸缩套3和按压紧固装置4。其中，可伸缩套3和按压紧固装置4组成密封锁紧装置。
喉罩导管1具有近端 1a和远端 1b，气管导管2具有前端 2a和后端 2b，气管导管2的前端 2a经所述喉罩导管1的远端 1b插入至所述喉罩导管1中，通过推动气管导管2的后端2b，气管导管2可沿后端 2b至前端 2a延伸形成的弧线自由滑动于所述喉罩导管1中。
喉罩导管1内壁设有从其近端 1a至远端 1b延伸的凸纹。并且所述气管导管2的外壁与喉罩导管1内壁上的凸纹接触，从而可有效减少所述喉罩导管1内壁与气管导管2外壁的接触面积，防止两壁之间的粘结，同时减少气管导管2在喉罩导管1中滑动的摩擦力，保证在喉罩导管1通气方式与气管导管2通气方式之间转换过程的顺畅。
喉罩导管1上在接近其远端 1b的部位设置有透明观察窗口11。
气管导管2的后端 2b与喉罩导管1的远端 1b通过可伸缩套3连接并密封，从而可以将所述气管导管2完全被所述的喉罩导管1和可伸缩套3包裹，从而在喉罩导管1通气方式与气管导管2通气方式转换的过程中，所述气管导管2不会暴露于外界，避免受到环境污染，使整个通气方式转换过程更加安全有效。
按压紧固装置4套在可伸缩套3上，通过按压和掰开实现对所述气管导管2的固定和释放。
可伸缩套3和按压紧固装置4组成密封锁紧装置可保证所述气管导管2与喉罩导管1联合通气装置的通气管道的气密性，避免了喉罩导管1通气方式与气管导管2通气方式转换过程中出现漏气，同时能固定气管导管2在喉罩导管1中的位置，提高了通气方式转换后的通气有效性，解决手术中因病人不同体位或体位变动时的喉罩位移问题。
可伸缩套3是透明可伸缩波纹管。可伸缩波纹管可随所述气管导管2在喉罩导管1中的滑动而沿其自身近端 1a到远端 1b的弧线自由伸缩，使得所述气管导管2始终与外部环境隔离。所述可伸缩套3的远端 1b连接有充气管5，所述充气管5远端 1b连接有单向阀6。
气管导管2带有显影蓝线和刻度。该显影蓝线和刻度的位置与透明观察窗口11的位置对应，医务人员可以通过所述透明观察窗口11观察显影蓝线和刻度，根据所观察到刻度值，可在喉罩导管1通气方式与气管导管2通气方式转换的过程中判断所述喉罩导管1内的气管导管2的近端 1a的相对位置，在气管导管上最小刻度为警示红线，在气管导管2转换为喉罩通气的操作中，当在观察窗口看到警示红线时，则表明气管导管2已拔出并收纳于喉罩导管中，转换顺利完成。从而实现对喉罩导管1通气方式与气管导管2通气方式转换过程的控制。
实施例2
如图2-4所示，所述的一种可转换式内置气管导管与喉罩联合通气装置包括喉罩导管1、气管导管2和螺旋式密封锁紧装置4＇。
喉罩导管1具有近端 1a和远端 1b，气管导管2具有前端 2a和后端 2b，气管导管2的前端 2a经所述喉罩导管1的远端 1b插入至所述喉罩导管1中，通过推动气管导管2的后端2b，气管导管2可沿后端 2b至前端 2a延伸形成的弧线自由滑动于所述喉罩导管1中。
喉罩导管1内壁设有从其近端 1a至远端 1b延伸的凸纹。并且所述气管导管2的外壁与所述喉罩导管1内壁上的凸纹接触，从而可有效减少所述喉罩导管1内壁与气管导管2外壁的接触面积，防止两壁之间的粘结，同时减少气管导管2在喉罩导管1中滑动的摩擦力，保证在喉罩导管1通气方式与气管导管2通气方式之间转换过程的顺畅。
螺旋式密封锁紧装置4＇，包括套设于所述气管导管外的螺盖4a，该螺盖4a设有内螺纹，该螺盖4a中设有按压件4d；套设于所述气管导管外的软体4c；以及，喉罩导管1的远端1b，该远端1b形成有外螺纹，且形成有容纳所述软体的空间4b。
如图2为拔出气管导管2进行喉罩通气时的联合体工作状态图，图3为气管插入进行气管通气的工作状态图，如图4所示，螺旋式密封锁紧装置4＇的具体实现方式，顺时针旋转紧固螺盖4a时，螺盖中的按压件4d下行会挤压软体4c，使其密封喉罩导管和气管导管之间的空隙，保证所述气管导管与喉罩导管联合通气装置的通气管道的气密性。同时，顺时针旋转紧固螺盖4a时，螺盖中的按压件4d会下行挤压软体4c使其向中心变形，与气管导管2管壁接触产生摩擦，从而实现压迫紧固，逆时针旋转紧固螺盖时，按压件4d上行，软体4c则恢复原形，软体向外回缩，不与气管导管2管壁接触，使得气管导管2可以滑动。
螺旋式密封锁紧装置4＇可保证所述气管导管2与喉罩导管1联合通气装置的通气管道的气密性，避免了喉罩导管1通气方式与气管导管2通气方式转换过程中出现漏气，同时锁紧装置4＇能固定气管导管2在喉罩导管1中的位置，提高了通气方式转换后的通气有效性，解决手术中因病人不同体位或体位变动时的喉罩位移问题。
进一步，如图5-6所示，所述的气管导管与喉罩导管联合通气装置还包括套设在气管导管2的后端2b与喉罩导管1的远端1b之间的可伸缩套3，可伸缩套一端与气管导管2的后端2b连接，另一端与螺盖4a连接。从而可以将气管导管2完全被所述的喉罩导管1和可伸缩套3包裹，从而在喉罩导管1通气方式与气管导管2通气方式转换的过程中，所述气管导管2不会暴露于外界，避免受到环境污染，使整个通气方式转换过程更加安全有效。
如图5-6所示，所述气管导管2带有显影蓝线和刻度。该显影蓝线和刻度的位置与所述透明观察窗口11的位置对应，医务人员可以通过所述透明观察窗口11观察显影蓝线和刻度，根据所观察到刻度值，可在喉罩导管1通气方式与气管导管2通气方式转换的过程中判断所述喉罩导管1内的气管导管2的近端 1a的相对位置，在气管导管上最小个刻度为警示红线7，在气管导管2转换为喉罩通气的操作中，当在观察窗口看到警示红线7时，则表明气管导管2已拔出并收纳于喉罩导管中，转换顺利完成。从而实现对喉罩导管1通气方式与气管导管2通气方式转换过程的控制。
所述可伸缩套3是透明可伸缩波纹管。所述可伸缩波纹管可随所述气管导管2在所述喉罩导管1中的滑动而沿其自身近端 1a到远端 1b的弧线自由伸缩，使得所述气管导管2始终与外部环境隔离。所述可伸缩套3的远端 1b连接有充气管5，所述充气管5远端 1b连接有单向阀6。
综上所述，本发明有效的解决了手术中因病人不同体位或体位变动时的喉罩位移问题，并实现了在适当的条件下喉罩导管1通气方式与气管导管2通气方式之间的切换，减少通气障碍以及在全麻苏醒拔管的过程中预防气管导管所致的气道高敏反应、血流动力学波动以及由此产生的并发症等问题。
以上结合最佳实施例对本发明进行了描述，但本发明并不局限于以上揭示的实施例，而应当涵盖各种根据本发明的本质进行的修改、等效组合。
