Description
技术领域
本实用新型涉及经鼻辅助通气装置领域，特别是一种双腔鼻咽通气道。
背景技术
近年来，消化道肿瘤病例逐渐上升，人们对胃肠道肿瘤的认识不断提高，胃肠镜诊治人数也日益增加，新的技术开展也层出不穷。随着胃肠镜诊疗人数的日益增加，为满足老百姓对胃肠镜诊疗舒适度的需求，无痛胃肠镜诊治数剧增。所谓无痛胃肠镜诊治，就是在胃肠镜检查与治疗前，选择一些起效快、恢复快、无蓄积、可控性强的麻醉药物，对病人进行镇静镇痛，甚至达到浅麻醉水平，减轻或消除胃肠镜诊治操作对病人的不良刺激，使病人没有痛苦感受。无痛胃肠镜诊治麻醉使用时，部分患者因肥胖，呼吸道狭窄和舌根后坠引起呼吸道阻塞导致氧分压下降而无法进行无痛胃肠镜诊治。同时胃肠镜诊治新技术开展层出不穷，包括胃镜下食管扩张术、胃镜下食管支架安置术、胃镜下经皮胃造瘘术、胃镜下超声引导穿刺等，均需要使用更为安全可靠且简便实用的麻醉通气装置，且由于胃镜占用口腔通气道，需要使用经鼻辅助通气装置。市面上可供选择的经鼻辅助通气装置相对较少，且现有的大部分经鼻辅助通气装置仅有单个输气通道，存在经鼻通气时漏气、无法监测呼气末二氧化碳浓度等问题。
实用新型内容
为解决现有技术中存在的问题，本实用新型的目的是提供一种具有双输气通道，能有效减少经鼻通气时漏气，且能监测呼气末二氧化碳浓度，并可进行喷射通气补充氧气量的功能全面的经鼻通气装置。
为实现上述目的，本实用新型采用的技术方案是：一种双腔鼻咽通气道，包括三叉管、第一支通气管、第二支通气管、呼气末二氧化碳检测管和喷射氧气补充管；所述三叉管的主接口为麻醉机或呼吸机通用接口，可对接常规呼吸回路，所述三叉管的分接口分别连接第一支通气管的一端和第二支通气管的一端；所述呼气末二氧化碳监测管的一端穿入第一支通气管且设于第一支通气管的内壁上，所述呼气末二氧化碳监测管的另一端设有密封螺母；所述喷射氧气补充管的一端穿入第二支通气管且设于第二支通气管的内壁上，所述喷射氧气补充管的另一端设有密封螺母。
优选地，所述第一支通气管和第二支通气管上设有防止密封螺母散落的固定装置。
优选地，所述第一支通气管和第二支通气管远离三叉管的一端为斜口，该斜口的倾斜角度为40度-50度。
优选地，所述第一支路气管和第二支路气管的外侧均设有刻度。
优选地，所述第一支通气管和第二支通气管上均设有防止通气管滑出的可调节的限位板。
本实用新型的有益效果是：
1、具有双腔通气管路，可以通过双侧鼻腔通气，克服常规单腔鼻咽通气道漏气严重，通气效率不高的缺点；
2、带有呼气末二氧化碳监测管和喷射氧气补充管，便于监测呼气末二氧化碳含量来判定患者自主呼吸状况和通气状态，并可喷射补充纯氧提高通气和供氧量；
3、双腔鼻咽通气道第一支通气管和第二支通气管上均设计有刻度和可调节的限位板，可有效判断通气管插入鼻腔深度和防止通气管滑出。
附图说明
图1为本实用新型实施例的结构示意图；
图2为呼气末二氧化碳监测管与第一支通气管的连接示意图；
图3为喷射氧气补充管与第二支通气管的连接示意图；
附图标记：1-主接口，2-三叉管，3-第一支通气管，4-第二支通气管，5-呼气末二氧化碳监测管，6-喷射氧气补充管，7-密封螺母，8-固定装置，9-限位板。
具体实施方式
下面结合附图对本实用新型的实施例进行详细说明。
实施例
如图1、图2、图3所示，一种双腔鼻咽通气道，包括三叉管2、第一支通气管3、第二支通气管4、呼气末二氧化碳监测管5和喷射氧气补充管6；所述三叉管2的主接口1为麻醉机或呼吸机通用接口，用于对接常规呼吸回路；所述三叉管2的分接口分别连接第一支通气管3的一端和第二支通气管4的一端；所述呼气末二氧化碳监测管5的一端穿入第一支通气管3且设于第一支通气管3的内壁上，所述呼气末二氧化碳监测管5的另一端设有密封螺母7；所述喷射氧气补充管6的一端穿入第二支通气管4且设于第二支通气管4的内壁上，所述喷射氧气补充管6的另一端设有密封螺母7。
使用时，将第一支气管和第二支通气管分别插入患者双侧鼻腔内，可通过呼气末二氧化碳监测管导出的气体，监测呼气末二氧化碳含量来判定患者自主呼吸状况和通气状态，如出现通气不足的情况，可通过喷射氧气补充管喷射补充纯氧提高通气和供氧量。如不需使用呼气末二氧化碳监测管和喷射氧气补充管时，可用密封螺母将呼气末二氧化碳监测管和喷射氧气补充管密封。
在其中一个实施例中，所述第一支通气管3和第二支通气管4上设有防止密封螺母7散落的固定装置8，该固定装置8可为塑料绳，在该塑料绳的一端设置一塑料套圈套设于第一支路气管上，该塑料绳的另一端与密封螺母7固定连接，另外在第一支通气管3和第二支通气管4上远离三叉管2的一端设置限位块防止套圈滑出。
在另外一个实施例中，所述第一支通气管3和第二支通气管4的外侧均设有刻度，所述第一支通气管3和第二支通气管4上均设有防止通气管滑出的可调节的限位板9。
刻度可帮助医疗人员掌握好支路通气管插入患者鼻腔的深度。限位板用于防止通气管滑出，具体作法是用医用胶带粘住限位板，然后通过医用胶带将限位板固定于鼻腔入口处。
在另外一个实施例中，所述第一支通气管3和第二支通气管4远离三叉管2的一端为斜口，该斜口的倾斜角度为40度-50度。
以上所述实施例仅表达了本实用新型的具体实施方式，其描述较为具体和详细，但并不能因此而理解为对本实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。
