本申请要求于2017年08月10日提交中国专利局的申请号为201710683535.7、名称为“效托式吸氧吸痰口咽通气道装置”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
本发明涉及医疗器械技术领域，特别涉及一种效托式吸氧吸痰口咽通气道装置。
背景技术
口咽通气道装置在手术全身麻醉苏醒期被普遍使用。在麻醉苏醒期，由于麻醉药物和肌肉松弛肌的残留或代谢产物的后续作用，使病人意识状态模糊或嗜睡，有的发生苏醒延迟，这种状态导致口咽腔肌群发生松弛，尤其以舌为甚，舌肌的松弛最容易导致舌的后坠，其结果容易导致咽腔狭小或狭窄或咽腔完全闭塞，使病人气道不通畅，从而容易在手术全身麻醉苏醒期造成病人通气障碍或通气功能丧失，肌体氧供、氧耗失去平衡，最为严重的是病人手术后缺氧死亡。上述情况如图25所示。
传统口咽通气道装置在手术全身麻醉苏醒期能够解决由病人意识状态模糊或嗜睡或发生苏醒延迟而导致口腔肌群发生松弛的问题，能够有效托起后坠的舌，在手术全身麻醉苏醒期能建立新的呼吸通道。
但是，手术全身麻醉苏醒期的病人是一个苏醒的过程，随着麻醉药物的逐渐降解和由病人的肌体从肝、肾和肺以及各种生物酶的代谢将麻醉药的分子结构破坏或排除；病人的感觉和意识状态随着这种麻醉药的逐渐代谢和排除逐渐清晰和恢复。并且，随着这种意识和感觉状态的恢复，病人不能耐受传统口咽通气道装置的刺激，特别是咽腔一些敏感区域受到传统口咽通气道装置刺激后会发生恶心、干呕等不良反射，严重会发生恶心呕吐，术中胃内大量的分泌物随着腹部压力的增加反流或喷射至口腔，然后又误吸至气道的气管支气管及肺部的情况，由于胃内容物属于酸性分泌物，PH值在0.9－3，这种酸性内容物立即导致肺泡表面活性物质－二软脂酰卵磷脂失活，以及肺泡细胞损伤；气管支气管痉挛以及反流物的堵塞，肌体不仅发生通气障碍而且会发生换气障碍，继发肺泡萎陷肺不张、肺水肿和肺部感染。
此外，传统口咽通气道装置刺激后会发生恶心、干呕等腹肌剧烈收缩容易导致伤口裂开；传统口咽通气道装置的使用刺激容易导致气道的高敏反应，继发循环动力学波动明显，血压升高、心率增快，肝脑等手术容易发生创面出血，导致手术失败；糖尿病、高血压、肥胖、鼾症等病人容易发生相关并发症，导致心脏病、脑血管意外、再次发生气道梗阻通气障碍。
发明内容
本发明的目的在于提供一种效托式吸氧吸痰口咽通气道装置，以解决现有的口咽通气道装置存在不良刺激作用容易导致危及病人生命的并发症发生的问题。
本发明的实施例通过以下技术方案实现：
一种效托式吸氧吸痰口咽通气道装置，包括：由近端至远端的内部通气道本体，以及与人体舌面平行宽度的托板；托板包括近端和远端弯曲部，近端位于内部通气道本体的正面、并构成管道的壁，远端弯曲部的弯曲角度为0°-180°；远端弯曲部的正面设有至少两个均匀分布的凸起或凹空或穿孔，凸起的牙面光滑、咽面直立为1-2mm或凹空的凹陷深度为0.5-1mm或穿孔的直径为1-3mm。
以上设计其目的是改变效托式吸氧吸痰口咽通气道装置的托板与舌面的粘合系数或摩擦面系数，以防止舌脱板后坠。
进一步的，托板的近端的宽度大于远端弯曲部的宽度；近端的两边形成有折边，且夹角为0°-180°。
这种设计的目的是形成对舌体部形成包合状态。
进一步的，效托式吸氧吸痰口咽通气道装置还包括：吸氧管道，吸氧管道设置在内部通气道本体的侧壁处。
进一步的，吸氧管道的侧壁至少间隔设有两个侧孔，多个侧孔沿内部通气道本体的近端分布至远端，且吸氧管道的远端的底孔封闭；侧孔的开孔角度与任意轴心线夹角为0°-180°。
这种设计的目的是使吸入的气体在进入气管后形成生理性混流状态，防止长时间对气道某个部位直接吹气导致局部组织脱水。
进一步的，效托式吸氧吸痰口咽通气道装置还包括：吸痰管道，吸痰管道设置在内部通气道本体的背面侧壁处，且吸痰管道的远端开口为吸痰孔。
吸痰孔的开口在导管底部，病人仰卧位时咽腔处于低位，有利于痰液聚集在吸痰孔的开口在导管底部周围，便利吸痰操作。
进一步的，效托式吸氧吸痰口咽通气道装置还包括：独立气囊，独立气囊位于内部通气道本体的背面设置，且独立气囊连接有充气阀。
这种设计的目的是独立气囊充气时，支撑托板可将舌面抬起，提拉舌根，使咽腔的空间加大，有利于麻醉苏醒期病人气道通畅，同时独立气囊充气顶在硬腭部位，该部位敏感性低，刺激小。
进一步的，效托式吸氧吸痰口咽通气道装置还包括：双层气囊，双层气囊位于内部通气道本体的背面设置，且双层气囊构成内部通气道本体的后壁。
这种设计的作用功能与独立气囊充气时类同，为了减少材料的应用，故使双层气囊构成内部通气道本体的后壁。
进一步的，内部通气道本体为圆形截面或椭圆形截面或异形截面。
一种效托式吸氧吸痰口咽通气道装置,包括：由近端至远端的内部通气道本体，以及与人体舌面平行宽度的托板；托板的近端为平板状、且平板状的两边内折、内折弧度为0°-180°，托板的远端为弯曲弧形结构、且弯曲弧度为0°-180°；托板的远端的弯曲弧形结构设有粘舌突，粘舌突包括穿孔、凸起或凹空；内部通气道本体的长度占效托式吸氧吸痰口咽通气道装置的整体长度的1.5/3-2.5/3；内部通气道本体为硬质圆形或椭圆形结构，或内部通气道本体为软质异形结构；内部通气道本体连通有充气阀，硬质圆形或椭圆形结构的背面设有充气囊构成管腔部分并与充气阀连通；或，软质异形结构附着在硬质部位并和管环与充气阀连通，充气时构成效托式吸氧吸痰口咽通气道装置的管壁；内部通气道本体的侧面管壁设有吸氧管道，且吸氧管道上开设有至少两个侧孔，邻近的两个侧孔之间气流两两对应形成夹角并在内部通气道本体内交汇形成涡流；吸氧管道的底部封闭；内部通气道本体的背面管壁设有吸痰管道。
相对于现有技术，本发明的技术方案至少具有以下优点或有益效果：
本发明的实施例提供的效托式吸氧吸痰口咽通气道装置，能够有效避开口咽腔刺激敏感地区，即能够有效避免刺激反射强度在5分以上的区域，从而减少对上述敏感区域的刺激面积，减少麻醉苏醒期的刺激强度。与传统口咽通气道装置比较，本发明的实施例提供的效托式吸氧吸痰口咽通气道装置使用安全、效率高，其刺激面积在非敏感反射区域，减少恶心呕吐和呛咳的发生，同时保证在麻醉苏醒期声门上气道通畅。尤其适用于肢端肥大症、鼾症、拔管后舌后坠等全身麻醉手术病人，减少麻醉后苏醒期的不良反应，符合工具顺序拔管法和舒适医疗的理念。

具体实施方式
下面将结合附图对本发明实施例的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，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。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1-图24所示，本发明实施例提供一种效托式吸氧吸痰口咽通气道装置，包括：由近端至远端的内部通气道本体11，以及与人体舌面平行宽度的托板10；托板10包括近端101和远端弯曲部102，近端101位于内部通气道本体11的正面、并构成管道的壁，远端弯曲部102的弯曲角度(α或β)为0°-180°；远端弯曲部102的正面设有至少两个均匀分布的凸起402(如图7所示)或凹空403(如图8所示)或穿孔401(如图6所示)，凸起402的牙面光滑、咽面直立为1-2mm或凹空403的凹陷深度为0.5-1mm或穿孔401的直径为1-3mm。
相对于现有技术，本发明实施例所述的效托式吸氧吸痰口咽通气道装置具有以下优势：
本发明实施例提供的效托式吸氧吸痰口咽通气道装置，能够有效避开口咽腔刺激敏感地区，即能够有效避免刺激反射强度在5分以上的区域，从而减少对上述敏感区域的刺激 面积，减少麻醉苏醒期的刺激强度。与传统口咽通气道装置比较，本发明实施例提供的效托式吸氧吸痰口咽通气道装置使用安全、效率高，其刺激面积在非敏感反射区域，减少恶心呕吐和呛咳的发生，同时保证在麻醉苏醒期声门上气道通畅。尤其适用于肢端肥大症、鼾症、拔管后舌后坠等全身麻醉手术病人，减少麻醉后苏醒期的不良反应，符合工具顺序拔管法和舒适医疗的理念。
此处需要补充说明的是，可以采用视觉模拟评分法，评价口咽腔的反射强度。在口咽腔部位，刺激反射最小是牙齿，设定其刺激反射强度为0，刺激反射最强的是舌根、咽后壁、近喉部为10，研究方法采用大样本数据，并根据上述数据绘制口咽腔刺激敏感地图。口咽腔敏感区域分布主要在咽腔，咽腔敏感区主要在舌根部、会厌部、咽隐窝等区域，如图26所示。
此外，我们提出了工具顺序拔管法,其内容是：在围术期全身麻醉苏醒期，研究一套实用工具，通过该工具解决全身麻醉苏醒期病人麻醉由深到浅，工具的转换使刺激由重到轻，集以消除呛咳反射、减少并发症的发生,在苏醒期减少麻醉药的应用，提高麻醉围术期的安全性，适用于高血压、糖尿病、肥胖、鼾症和特殊手术病人。运用本工具顺序拔管法可以解决麻醉苏醒期利用工具安全、顺序的拔管，无需应用麻醉苏醒期药物催醒、或为了减少刺激导致的并发症追加应用麻醉药导致麻醉苏醒延迟，麻醉后呼吸抑制等一系列风险。
其中，如图5所示，上述托板10的近端101的宽度大于远端弯曲部102的宽度；并且，近端101的两边形成有折边，该折边夹角θ为0°-180°。
在本实施例中，为了较好地整合吸氧功能，如图1和图2所示，上述效托式吸氧吸痰口咽通气道装置还包括：吸氧管道1，该吸氧管道1设置在内部通气道本体11的侧壁处。其中，上述吸氧管道1的侧壁至少间隔设有两个侧孔2，多个侧孔2沿内部通气道本体11的近端分布至远端，且吸氧管道1的远端的底孔封闭；具体地，侧孔2的开孔角度为任意轴心线的0°-180°。
在本实施例中，为了较好地整合吸痰功能，如图3和图4所示，上述效托式吸氧吸痰口咽通气道装置还包括：吸痰管道7，该吸痰管道7设置在内部通气道本体11的背面侧壁处，且吸痰管道7的远端开口为吸痰孔。
在本实施例中，如图13-图16所示，上述效托式吸氧吸痰口咽通气道装置还包括：独立气囊5，该独立气囊5位于内部通气道本体11的背面设置，且独立气囊5连接有充气阀6。实际使用时，如图17和图18所示，当独立气囊5处于非充气状态(也即塌陷状态)时，效托式吸氧吸痰口咽通气道装置插入口咽腔内；充气后，独立气囊5支撑效托式吸氧吸痰口咽通气道装置的通气道后壁，抬举舌中部，保持口咽腔畅通。
在本实施例中，如图19-图22所示，上述效托式吸氧吸痰口咽通气道装置还包括：双 层气囊9，该双层气囊9位于内部通气道本体11的背面设置，且双层气囊9构成内部通气道本体11的后壁。具体地，双层气囊9与充气阀6连通，且双层气囊9与硬质管壁和管环8密合连接，当双层气囊9处于非充气状态(也即塌陷状态)时，将效托式吸氧吸痰口咽通气道装置插入口咽腔内，如图23所示；充气后，双层气囊9支撑效托式吸氧吸痰口咽通气道装置的通气道后壁，抬举舌中部，保持口咽腔畅通，如图24所示。
在本实施例中，本发明实施例提供的效托式吸氧吸痰口咽通气道装置中，上述内部通气道本体11可以为圆形截面或椭圆形截面或异形截面。当然，具体截面形状，在此不做限制，合理即可。
本发明实施例提供的效托式吸氧吸痰口咽通气道装置可以利用注模或旋转模制或其它类型的制模工艺方式制造。
本发明实施例还提供一种效托式吸氧吸痰口咽通气道装置,如图1-图24所示，包括：由近端至远端的内部通气道本体11，以及与人体舌面平行宽度的托板10；托板10的近端101为平板状、且平板状的两边内折、内折弧度为0°-180°，托板10的远端为弯曲弧形结构、且弯曲弧度为0°-180°；托板10的远端的弯曲弧形结构设有粘舌突4，该粘舌突4包括穿孔401、凸起402或凹空403；内部通气道本体11的长度占效托式吸氧吸痰口咽通气道装置的整体长度的1.5/3-2.5/3；内部通气道本体11为硬质圆形或椭圆形结构，或内部通气道本体11为软质异形结构；内部通气道本体11连通有充气阀6，硬质圆形或椭圆形结构的背面设有充气囊构成管腔部分并与充气阀6连通；或，软质异形结构附着在硬质部位并和管环8与充气阀6连通，充气时构成效托式吸氧吸痰口咽通气道装置的管壁；内部通气道本体11的侧面管壁设有吸氧管道1，且吸氧管道1上开设有至少两个侧孔2，邻近的两个侧孔2之间气流两两对应形成夹角并在内部通气道本体11内交汇形成涡流；吸氧管道1的底部封闭；内部通气道本体11的背面管壁设有吸痰管道7。
在麻醉苏醒期麻醉药物的代谢是一个缓慢的过程，残留在体内的麻醉药和其代谢产物将继续发挥麻醉效能，这种效能在强刺激条件下表现为对刺激不能耐受，诱发麻醉苏醒期并发症，过早的拔出气管导管，病人由于麻醉药的残留作用，继续进入昏睡或麻醉状态，常见的并发症有咽腔肌肉松弛、舌后坠导致气道梗阻。麻醉苏醒期刺激性较强的气管导管拔出后植入刺激强度小口咽通气道是合理的选择，传统口咽通气道装置在设计上没有规避口咽腔敏感部位，容易诱发新的不良反射，本发明提供的效托式吸氧吸痰口咽通气道装置能够规避或减少口腔内不良反射，同时解决在临床麻醉过程中，效托式吸氧吸痰口咽通气道装置整合吸痰吸氧功能后使吸痰吸氧操作便捷。应用工具顺序拔管法是为了应用几种新型工具的优势、安全的、顺序的、减少刺激，实现拔管，减少传统麻醉通过追加麻醉药物操作方式来抑制工具刺激造成的损伤，同时能够提高工具的效率，解决传统工具不能解决 的问题，例如高血压、糖尿病、肥胖、鼾症和特殊手术病人麻醉后苏醒期的安全通气。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
