技术领域
本发明涉及医疗器械技术领域，具体为重症、危重症及ICU患者的床旁便携式可视化鼻胃肠营养管留置的标准路径及其留置系统。
背景技术
重症或危重症患者以及ICU内的患者往往因意识障碍或者处于镇静镇痛、机械通气状态而无法经口喂养，经鼻胃管和鼻肠管进行喂养是这些患者最常用的肠内营养的通路，虽然胃管是ICU患者最常见的营养通路，但是因各种原因出现胃喂养不能耐受、胃排出梗阻、胃瘫或者有高误吸风险的患者而需要留置鼻肠管进行幽门后喂养的情况也非常普遍，目前临床上的各种鼻肠管留置技术中，在ICU最实用的是床旁手法盲插技术，既往使用的螺旋型鼻肠管采用盲插法置管成功率总体偏低，需要药物和针刺的手段促进肠蠕动，该法仅在床旁徒手置管，操作简单易行，无需特殊设备，是目前危重患者床旁置管早期实施肠内营养的有效方法，该方法有一定的误置入气道的概率，一旦误入气管会发生致命的风险；该方法留置后需要拍摄X线以确定位置，喂养时间上会有一定的延后性；该方法有15％-20％的患者无法一次留置成功需要反复调整，一次置管不成功后反复盲插置管容易对病人鼻黏膜以及食道、胃部带来损伤，反复拍片定位带来费用的增加和辐射的不良的缺点，对于留置一次不成功的情况，留置鼻肠管的医护人员围绕肠管留置的工作量明显大幅度增加，另外，小部分患者多次留置不成功的患者最终仍然需要胃镜辅助下给予留置。
现今采用的盲插置管手法在对无胃动力患者螺旋管放置成功率57％，因此法留置时间长，成功率低不合适ICU的患者的使用，在医疗设备飞速进步的今天，内窥镜的可视下置入鼻胃肠营养管是解决上述不足的最佳方法。

在本实施例中，内窥镜4管径小于2.6mm，内窥镜4长度在150cm-200cm之间，内窥镜4一端镜头周围安装有照明灯，照明灯为冷光灯，内窥镜4一端侧壁设置为曲面；内窥镜4的镜头可以通过冷光源保持良好的视野，内窥镜4的一端做曲面处理，光滑不易损伤胃肠粘膜，整体柔软而有一定的弹性以便对肠管有合适的支撑，易于鼻肠管5的引导，内窥镜4部份整体密闭一体，易于消毒，符合院感防控的规定和要求。
参阅图1-3，鼻胃肠营养管5为一次性材料，鼻胃肠营养管5的材质为聚醚型亚聚氨酯，鼻胃肠营养管5规格为12～14Fr，内窥镜4可置入鼻胃肠营养管5内部，接收显示器1包括无线接收器、显示器和操作键，无线接收器安装在接收显示器1内部，显示器和操作键均安装在接收显示器1内部，操作键位于显示器一侧，无线接收器与无线传输装置3相匹配，接收显示器1通过无线接收器与无线传输装置3与内窥镜4无线连接；鼻胃肠营养管5材料为一次性使用，符合国家医用营养管的相关标准，前端开口部分为曲面光滑柔软不易损伤胃肠粘膜。
参阅图5-10在具体应用中，在前期的预研的探索中，通过大量实践应用本系统的内窥镜4，确定了从鼻甲、食道、贲门、胃大弯以及到幽门部和十二指肠的路径中起指示性作用的定位点的标志性图像，并按照这些定位点的指示意义，快速找到并通过幽门，完成十二指肠内的置管。熟练的医师整个置管的时间控制在15min以内，通过图4-6与图7-9之间的对比可以看出本系统可以较为清晰的分辨出鼻肠管5在患者体内的位置。
本实用发明的工作原理及使用流程：使用时通过将鼻胃肠营养管5套设在内窥镜4侧壁，通过将内窥镜4置入患者体内从而将鼻胃肠营养管5带入 患者体内，通过操控手柄2的另一端的无线传输装置3，可以将内窥镜4拍摄到的画面通过接收显示器1显示实时的图像，通过设置操控手柄2可以控制内窥镜4前端进行指向性弯曲以便指引方向，以此来调节鼻胃肠营养管5的置留位置，以便在绝大多数情况下，在胃内可以快速找到这些定位点，并按照这些定位点的指示意义，快速找到并通过幽门，完成十二指肠内的置管。
实施例2
该设备内窥镜4可以更改照明设备和更为清晰的摄像头，进一步扩大视野，对于进一步以便快速定位幽门的位置，缩短置管时间，也是非常重要的环节，如果内窥镜4的直径为2mm，即可以使用12Fr的鼻肠管5，让患者更加舒适。
本系统针对重症、危重症及ICU患者的床旁留置鼻肠管5而设计，使用的全过程和胃镜的操作的过程类似，在使用手法上和ICU每日工作中使用的纤支镜类似。另外因本系统内窥镜4的微型化，可置入12-14Fr的鼻肠管5内，和平常下鼻肠管5一样，对患者几乎无不良影响，重症和危重症患者一般处于严密的生命监测下，ICU内危重症患者往往的处于良好的镇静镇痛和机械通气下以及处于持续的生命体征监测下，患者的安全更有保障。在设备的消毒和院感防控中，在使用本设备前后，可按内窥镜4的相关要求进行消毒，然后放入专门的内窥镜4消毒柜中备用，虽然本产品可视为微缩版的胃镜，但是其内窥镜4系统没有空腔，是全密闭封装，使用后消毒以及保管比胃镜和纤支镜更方便和容易，有助于院感的防控。
以上内容是结合具体实施方式对本发明作进一步详细说明，不能认定本发明具体实施只局限于这些说明，对于本发明所属技术领域的普通技术人员来说，在不脱离本发明的构思的前提下，还可以做出若干简单的推演或替换，都应当视为属于本发明所提交的权利要求书确定的保护范围。
