Description

低损伤可视喉镜
本申请要求于2016年6月17日提交中国专利局、申请号为201620589578.X，申请名称为“低损伤可视喉镜”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及一种医疗器材，具体涉及低损伤可视喉镜。
背景技术
目前临床医学的麻醉与急救时需要进行气管插管建立人工气道所需要的设备是普通麻醉喉镜和可视喉镜这两类设备，这两类设备可以完成大多数工作需要；气管插管工作当中会遇到一定失败和损伤并发症的问题，主要有以下六类：一、喉镜带来的咽喉部的损伤问题，目前我国使用的喉镜镜片结构大致相同，我国目前使用的喉镜镜片弯曲度和人体口腔咽喉部生理结构不一致，在正常使用时候对咽喉部组织有一定力度和时间的压迫和损伤，(普通喉镜显露喉部声门时所需上提用力约为5.4kg，视频喉镜显露喉部结构所需上提用力0.5～1.4kg《中华实用诊断与治疗杂志》2014年1月第28卷第1期第59页)；二、在使用时需要较大程度的打开病人嘴巴，在遇到张口困难、小嘴巴、下颌骨骨折不能张口、由于过度肥胖使颈椎活动受限以及颈椎骨折导致的头部不能后仰的情况下使用是受限制的；三、失败率，在正常人群使用可视喉镜，气管导管的置入大多需要使用管芯塑型，塑型后的气管导管在抵达声门附近后，此时拔除管芯推送导管前进的过程中导管前进方向有可能会发生偏移从而可能滑出声门导致插管失败。四、视野盲区：放置气管导管的时候导管会遮蔽一部分摄像头的视野造成视觉盲区，增加失败率和损伤的可能性；五、可视喉镜在使用中需要助手拔除管芯，操作繁琐延长插管时间。六、可视喉镜必须使用的管芯带来的损伤：用可视喉镜都需要用管芯把导管塑形，导管被管芯塑形后强度增加，在插管过程中有可能损伤声带和环杓关节脱位。
发明内容
本申请的目的在于提供低损伤可视喉镜，解决喉镜进入咽喉部和声带的过程中对咽喉造成损伤的问题。
为解决上述的技术问题，本申请采用以下技术方案：
低损伤可视喉镜，包括手柄和镜片，手柄与镜片前端相连，镜片上设有摄像通路，摄像通路包括第一摄像孔和第二摄像孔，第一摄像孔与第二摄像孔横向排设且分别对准镜片的末端，这样使喉镜镜片在送达咽喉部时，第一摄像孔和第二摄像孔内的摄像头可以获得一个可视范围并互补了视野盲区，防止镜片损伤咽喉。
作为优选，上述低损伤可视喉镜的手柄与镜片片身在水平方向上垂直，这样使镜片进入口腔咽喉部时，更容易通过手柄调节镜片方向且不被胸部干涉。
作为优选，上述低损伤可视喉镜的镜片为与人体口腔咽喉部舌根会厌弧度相吻合的U形片，这样减少了对口腔内舌根和咽喉部组织的压迫，保护了咽喉部组织。
作为优选，所述人体口腔咽喉部舌根会厌弧度过人体口腔内上门牙、硬腭最高点和会厌根部三点。
作为优选，上述低损伤可视喉镜的镜片弧度为1.9199rad至3.1415rad，这样使镜片适用于青少年、幼儿和成年人，减少了对青少年、幼儿和成年人的口腔内舌根和咽喉部组织的压迫，保护了咽喉部组织。
作为优选，上述低损伤可视喉镜的镜片上设有导管载体，导管载体指向镜片末端，导管载体设置在摄像通路的一侧，这样使导管送入人体咽喉部到达声门内的过程中导管前进方向是朝向镜片末端,且该方向是可控的，并不容易发生偏移，从而保护了人体的咽喉部，避免损伤声门。
作为优选，上述低损伤可视喉镜的导管载体包括导管盖和导管沟，导管盖与导管沟活动连接，这样便于插管操作和清洗消毒导管载体的内部。
作为优选，上述低损伤可视喉镜的手柄为柱体，手柄上设有第三通孔，第三通孔的两个端口分别位于手柄的上顶面和侧面，第三通孔内装有摄像头的线，这样避免摄像头的线干扰操作。
作为优选，上述低损伤可视喉镜的第一摄像孔与第二摄像孔中分别装有摄像头，手柄上设有电子屏幕，电子屏幕能在与手柄的连接处转动，手柄内装设有电池槽，电池槽与电子屏幕电连接，电子屏幕与摄像头电连接，这样使喉镜更便携。
作为优选，上述低损伤可视喉镜的导管载体与镜片末端之间设有导管导向板，这样使导管载体内的导管指向镜片末端，避免导管窜动到其他位置，碰伤咽喉。
与现有技术相比，本申请的有益效果是：采用双摄像镜头，使喉镜进入人体咽喉部时产生更大的视野面积，从而使喉镜准确的进入人体咽喉部，并解决了现有可视喉镜在显露声门后放置气管导管时导管遮蔽视野产生盲区这一问题；同时使用与人体口腔咽喉部弧度相适配的镜片，减小了镜片对咽喉的压迫；手柄与镜片片身在水平方向上垂直的设计方便了镜片进入咽喉部；电池槽与摄像头的设置使喉镜更便携，采用可分离的导管载体放置气管导管，使得插管简单迅速和低损伤；镜片上面的导管导向板把导管前进的方向控制在镜片末端，避免导管窜动到其他位置，碰伤咽喉。

如图3所示：低损伤可视喉镜，包括手柄1和镜片2，手柄1与镜片2前端相连，镜片2上设有摄像通路3，摄像通路3包括第一摄像孔31和第二摄像孔32，第一摄像孔31与第二摄像孔32横向排设且分别对准镜片2末端，镜片2上设有导管载体4，导管载体4指向镜片2末端，导管载体4设置在摄像通路3的一侧，导管载体4包括导管盖41和导管沟42，导管 盖41与导管沟42活动连接，在插管的过程中，导管盖41和导管沟42的分离式设计，使插管工作更方便，同时也便于清洗消毒导管载体4的内部。
实施例9
如图1和2所示：低损伤可视喉镜，包括手柄1和镜片2，手柄1与镜片2前端相连，镜片2上设有摄像通路3，摄像通路3包括第一摄像孔31和第二摄像孔32，第一摄像孔31与第二摄像孔32横向排设且分别对准镜片2末端，手柄1为柱体，手柄1上设有第三通孔7，第三通孔7的两个端口分别位于手柄1的上顶面和侧面，第三通孔7内装有从镜片片身伸出的线，这样防止手握住线的不稳定性，避免摄像头的线对操作的影响。
实施例10
如图2、3、4、5和6所示：低损伤可视喉镜，包括手柄1和镜片2，手柄1与镜片2前端相连，镜片2上设有摄像通路3，摄像通路3包括第一摄像孔31和第二摄像孔32，第一摄像孔31与第二摄像孔32横向排设且分别对准镜片2末端，第一摄像孔31与第二摄像孔32中分别装有摄像头，手柄1上设有电子屏幕8，电子屏幕8能在与手柄1的连接处转动，手柄1内装设有电池槽，电池槽与电子屏幕8电连接，电子屏幕8与摄像头电连接，电子屏幕8能显示摄像头拍摄的画面，这样喉镜不用外接显示设备，提高了喉镜的便携性能。
实施例11
如图1、2、3和6所示：低损伤可视喉镜，包括手柄1和镜片2，手柄1与镜片2前端相连，镜片2上设有摄像通路3，摄像通路3包括第一摄像孔31和第二摄像孔32，第一摄像孔31与第二摄像孔32横向排设且分别对准镜片2末端，导管载体4与镜片2末端之间设有导管导向板10，这样使导管载体4内的导管指向镜片2末端，并对准了声门，并减小了喉镜的压力，增大了喉镜的受力面积。
本申请工作原理：首先打开病人嘴巴，左手拿着手柄把镜片顺嘴巴插入口腔通过舌面和舌根，镜片末端到达会厌根部，轻轻上挑会厌显露声门，观察咽喉部情况，右手把气管导管插入声门内，先去掉导管盖，将右手固定气管导管，左手将喉镜镜片退出来，完成一次喉镜的操作。
本申请的有益效果是：
采用双摄像镜头，使喉镜进入人体咽喉部时产生更大的视野面积，从而使喉镜准确的进入人体咽喉部，并解决了现有可视喉镜在显露声门后放置气管导管时导管遮蔽视野产生盲区这一问题；同时使用与人体口腔咽喉部弧度相适配的镜片，减小了镜片对咽喉的压迫；手柄与镜片片身在水平方向上垂直的设计方便了镜片进入咽喉部；电池槽与摄像头的设置使喉镜更便携，采用可分离的导管载体放置气管导管，使得插管简单迅速和低损伤；镜片上面的导管导向板把导管前进的方向控制在镜片末端，避免导管窜动到其他位置，碰伤咽喉。
尽管这里参照本申请的多个解释性实施例对本申请进行了描述，但是，应该理解，本领域技术人员可以设计出很多其他的修改和实施方式，这些修改和实施方式将落在本申请公开的原则范围和精神之内。更具体地说，在本申请公开、附图和权利要求的范围内，可以对主题组合布局的组成部件和/或布局进行多种变型和改进。除了对组成部件和/或布局进行的变形和改进外，对于本领域技术人员来说，其他的用途也将是明显的。
