Description

种安全三通道喉罩 技术领域
本发明涉及一种新型喉罩装置， 具体涉及一种新型安全三通道喉罩。 背景技术
为了维持无意识的病人呼吸换气，必须给其建立呼吸通道。传统的方式是使用气管插管。 但气管插管存在较大缺陷： 首先是难于快速和适当将管道插入气管， 因为这是需要很高技术 的一种处理过程， 往往还要借助喉镜等装置， 因此必须有一定技术的操作者才能实施， 就使 得这一方式在一些需要尽快在病人体内建立呼吸通道以争取治疗时间的情况 （例如危重患者 抢救等） 带来很多不便； 其次， 气管插管在使用过程中易引起病人的心肺反应、 喉咙疼痛、 咳嗽或喉痉挛等， 而且由于插入时需要控制病人的头和颈部， 使得病人颈部还可能受到伤害； 另外， 为了方便插入， 气管插管的远端尺寸必须足够小， 这就使得产生的呼吸通道较小或较 窄。
喉罩通气装置是另外一种建立呼吸通道的新型装置。 使用喉罩通气装置能较容易地插入 病人体内建立呼吸通道，一般操作者经过短期培训就能使用， 因此在急救的场合也非常适用。 由于喉罩通气装置不需要与气管敏感的内部通道相接触就可以向病人的肺充气， 因此病人受 刺激的程度大为减轻， 而且所建立的呼吸通道尺寸显著大于由气管插管所建立的呼吸通道。 同时， 由于插入时对病人头、 颈等部位的操纵动作较小， 因此对病人的潜在伤害也较小。 由 于上述的优势， 喉罩通气装置自 1983年发明以来越来越流行。
现有的喉罩通气装置还存在如下缺陷： 与呼吸装置的接口只有一个， 在需要给病人进行 纤支镜检査治疗或吸痰等操作时， 必须拔下呼吸装置， 影响了呼吸通道的顺畅； 而且， 连通 食道的导管通道尺寸较小， 胃镜等内窥镜无法通过。
另外， 现有的喉罩通气装置也有其缺陷： 由于喉罩使用原理是插入喉部充气后膨胀形成 气囊弹性体， 与喉腔贴合， 起到密封作用， 防止在呼吸过程中气体从喉罩与喉腔的缝隙中泄 漏， 然后通过喉罩上的导管与呼吸设备连接给患者通气。 气囊一般是采用硅胶或塑胶等原料 经模具塑形制成， 再通过粘接工艺形成气囊， 如果粘接不良或材料本身气密性能不好， 在一 定压力下会造成漏气现象， 这样就无法起到密封作用， 假如这种情况不能及时发现， 就极有 可能发生医疗风险，不能安全地给患者供气，这就造成医护人员在选择喉罩应用时有所担忧， 不能更广泛和长时间地使用喉罩。 发明内容
本发明所要解决的技术问题是克服现有技术中所存在的上述不足， 而提供一种新型安全 三通道喉罩， 在保持患者呼吸通道顺畅的基础上， 还可以向食道和气道伸入器械进行检查、 治疗或吸痰等操作， 同时能实时、 准确、可靠地检测气囊的压力状况， 让医护人员能更便捷、 更安全、 更广泛地使用该喉罩。
为了实现上述目的， 本发明所采用的技术方案如下：

如图 1所示， 本发明新型安全三通道喉罩的整体结构示意图， 该安全三通道喉罩包括压 力部分 100和喉罩部分 200。
如图 2所示， 为本发明压力检测部分 100， 能够实时量化检测气囊的压力， 其包括有一 量化检测气囊压力的测压表 3， 该测压表 3与所述气囊连通， 该新型安全三通道喉罩还包括 有一单向阔 2， 所述单向圆 2也与所述气囊连通。
本实施例采用可量化检测气囊的测压表 3， 该测压表 3选用为表盘指针式或数字式测压 表， 以方便医护人员实时查看。 因此， 该测压表与所述气囊连通， 可以实时、 准确、 可靠地 检测气囊的压力状况， 及时发现漏气等不良现象， 让医护人员能长期、 长时间、 更广泛地安 全使用喉罩。
本实施例与气囊连通的单向阀 2， 可以根据测压表 3检测到的压力状况对气压进行实时 调整， 对气囊内的压力进行矫正， 让气囊中的气压恢复到安全范围内， 进而提高本发明的安 全性能。
如图 2所示， 本实施例中测压表 3与单向阀 2共用一根充气管 1与所述气囊连通， 及图 中充气管只有一根充气管， 这样可以在物理上简化设备， 方便生产和使用。
当然， 需要说明的是， 本发明只要测压表 3和单向阀 2能够与气囊连通即可， 并不限定 其具体的连接方式， 比如测压表 3与单向阔 2还可以分别通过一根充气管与气囊连通 （图中 未示意出），即测压表 3通过一根充气管与气囊连通，单向阀 2通过另一根充气管与气囊连通， 这些形式都本发明的保护范围。
如图 2所示， 本实施例中单向阔 2与充气管 1通过第一导管 7连通， 测压表 3与充气管
1通过第二导管 8连通， 以便于实时检测气囊气压， 也有利于通过单向阔 2对气囊的气压进 行纠正。
同样， 需要说明的是， 本发明只要测压表 3和单向阀 2能够与气囊连通即可， 并不限定 其具体的连接方式， 比如： 单向阔 2与充气管 1一体设置（图中未示意出）， 即不通过第一导 管 7直接连接到充气管 1上， 又比如： 单向阔 2与连接管 5—体设置（图中未示意出）， 即也 不用第一导管 7直接连到连接管 5上， 这些形式都本发明的保护范围。
如图 2所示， 在测压表 3上设置有一连接头 4， 在所述测压表 3的连接头 4与所述第二 导管 8之间的连接处设置有一连接管 5， 用该连接管 5将测压表 3和第二导管 8连接起来。
其中， 测压表 3的连接头 4与所述连接管 5之间为不可拆卸固定密封连接或者可拆卸密 封连接， 即是测压表 3可以与所述连接管 5固定连接， 也可以是活动连接。
当其活动连接时， 在所述连接管 5上可以配置一密封塞 6， 在不需要插入所述测压表 3 检测气囊的压力状况， 且气囊已充气时， 可用密封塞 6密封盖住所述连接管 5上的开口， 防 止漏气。
如图 3所示， 连接头 4的外圆周壁从上至下逐渐变小， 且所述连接头 4底端设有圆弧面 41。所述圆弧面 41能够导引所述连接头 4顺利进入所述连接管 5与其配合连接，所述连接头 4的外圆周壁从上至下逐渐变小， 以便于所述连接头 4进入所述连接管 5内后， 所述连接头 4 的外壁与所述连接管 5的内壁紧密配合， 密封效果良好。
如图 3所示， 在连接头 4的外圆周壁上设置有至少一个防漏凹槽 42， 所述防漏凹槽 42 具有上斜面 421和下底面 422， 所述下底面 422水平设置。 通过在所述连接头 4的外壁上设 置所述防漏凹槽 42， 使得所述连接头 4插入所述连接管 5内后， 二者之间的密封连接效果更 好。
需要说明的是， 上述为本发明连接头 4与所述连接管 5的密封形式的一种， 其他将两者 密封连接在一起的密封形式都是本发明的等效保护范围， 比如采用加密封垫圈或者利用材料 的弹性挤压密封等。
本实施例中的新型安全三通道喉罩 100的充气管 1上连接有测压表 3， 所述测压表 3的 连接头 4插入连接管 5内与所述连接管 5配合密封连接后， 所述测压表 3能实时、 准确、 可 靠地检测所述气囊 201的压力状况， 且所述气囊 201的压力状况能通过所述测压表 3进行量 化， 配合所述单向睛 2使用， 可对所述气囊 201内的压力进行矫正， 让医护人员能及时发现 漏气或压力过大过小等不良现象， 能放心长时间使用， 可以更安全、 更广泛地使用喉罩。
如图 1、 4、 5所示， 本发明新型安全三通道喉罩包括通道管 202和气囊 201， 所述通道 管 202与所述气囊 201连接。
如图所示， 通道管 201内分别设置有气道导管 209、 食道导管 208和器械导管 207。 其中，气道导管 209的机器端 2091与呼吸机的标准接口连接，所述气道导管 209的病人 端 205开口与人体的气道口对应设置。使用时，呼吸机与所述气道导管 209的所述机器端 2091 连接后， 操作者可对患者实施机械通气。
其中，所述食道导管 208的机器端 2081设置有可供食道器械出入的食道器械开口，所述 食道导管 208的病人端 203开口与人体的食道口对应设置。所述食道导管 208的的机器端 2081 可供内窥镜 （例如胃镜） 或胃管等器械进入并通过， 所述食道导管 208的病人端 203与所述 人体的食道对应设置。 使用时， 内窥镜 （例如胃镜） 或胃管等器械从所述食道导管 208的所 述机器端 2081开口进入，经所述食道导管 208再从所述病人端 203开口伸出并进入所述人体 食道， 以实施内镜检査治疗或食道引流或胃肠道营养等操作。 为了便于内窥镜 （例如胃镜） 或胃管等器械能通过所述食道导管 208， 所述食道导管 208的内径为 4-10mm。 其中，所述器械导管 207的机器端 2071设置有可供气道器械出入的气道器械开口，所述 器械导管 207的病人端 204开口与人体的气道口对应设置。 使用时， 器械导管 207的机器端
2071可供纤支镜或吸痰管等器械进入并通过， 以实施纤支镜检査治疗或吸痰等操作， 所述器 械导管 207的病人端 204也与所述人体的所述气道对应设置。 使用时， 纤支镜或吸痰管等器 械从所述器械导管 207的所述机器端 2071开口进入， 经所述器械导管 207再从所述病人端
204开口伸出并进入所述人体气道， 以实施纤支镜检查治疗或吸痰等操作。
其中， 器械导管 207在所述通道管的机器端设有单向阔和 /或塞子。 所述器械导管 207不 使用时， 所述塞子 206盖合于所述器械导管 207的所述机器端 2071开口上， 所述器械导管
207处于闭合状态， 防止漏气。 当需要使用所述器械导管 207进行器械操作时， 可以打开所 述塞子 206， 将器械插入并进入所述人体气道， 实施操作， 这样既能不影响患者的呼吸通道 顺畅， 又能实施其他医疗操作。
当然， 本发明并不限于此， 在其他实施例中， 所述器械导管 207的所述机器端 2071也可 以设有单向阔， 或者所述器械导管 207的所述机器端 2071设有所述塞子 206和所述单向阀。
本发明结合人体喉部气道解剖结构特点， 为使纤支镜等器械能方便进入患者气道， 器械 导管 207的病人端 204下方设有弧形导槽 2011， 所述弧形导槽 2011位于所述气囊 201上。 当器械伸出所述器械导管 207后能顺着所述弧形导槽 2011直接进入所述人体气道。
本发明的气道导管 209的病人端、 所述器械导管 207的病人端分别与人体的气道对应设 置， 在使用时， 可使操作者在保持患者呼吸通道顺畅的同时， 进行纤支镜检查治疗或吸痰等 操作， 简化操作步骤， 降低对患者的影响， 而且与人体的食道对应设置的所述食道导管 208 可让胃镜等内窥镜或胃管进入并通过， 便于实施检査治疗或胃肠道营养等操作。
因此， 本实施例不仅具有量化检测气囊压力能力， 可实时、 准确、 可靠地检测气囊的压 力状况， 提高本发明使用安全。 而且， 本实施例还能够在保持患者呼吸通道顺畅的同时， 向 食道和气道伸入器械进行检査、 治疗或吸痰等操作， 从而简化操作步骤， 进一步降低对患者 的影响。 经过上述两个方面的综合改良， 从而进一步的提高了本发明的安全性能。
上述说明是针对本发明较佳可行实施例的详细说明， 但实施例并非用以限定本发明的专 利申请范围， 凡本发明所揭示的技术精神下所完成的同等变化或修饰变更， 均应属于本发明 所涵盖专利范围。
