Description

双囊气管插管 fe^领域 本发明属于医疗器械领域,涉及一种气管插管, 具体涉及一种用于手术麻醉 和危重患者抢救的双囊气管插管。 背景 气管插管在临床医学中使用广泛, 如心脏复苏、伴有呼吸障碍的急危重症患 者抢救手术、全麻手术等。气管插管是急救工作中常用的重要的医疗用品, 是呼 吸道管理中使用最广泛、 最快捷、 最有效的医疗器械之一, 对抢救患者生命、降 低病死率起到了至关重要的作用。 传统的气管插管存在一些设计缺陷,使得医护人员对气管插管的插入深度位 置不易掌握,血液组织液容易流入气道或食道。一般医生会凭借经验控制插入深 度和位置, 或使用纱布类的填充物来把气管插管固定在咽喉处, 防止手术过程中 的血液、 分泌物、 异物等进入咽喉深处, 阻塞呼吸道或进入食道。 但由此的医疗 事故很多, 存在严重的医疗隐患。 近年来对气管插管的结构和功能进行了改进,设计出双囊气管插管相关专利 文献如下: 中国发明专利说明书 "单腔双囊气管插管导管", 授权公告号 CN2617396Y, 授权公告日 2004年 5月 26日, 披露了: 一种临床用单腔双囊气管 插管导管,由单腔气管导管,导管出口,导管侧孔,双气囊,气囊充, 放气气孔和充 气阀构成。 该双囊互为独立,可以交叉放气和充气。 其优点: 能防止口腔分泌物或食管返流物进入气管和肺,减少气囊对气管内 壁压迫而造成的损伤,减轻对病人的损害和减少病人的费用 不足之处: 所述单腔双囊气管插管导管均用于封闭患者气管, 无法阻挡口腔 内血液、 分泌物、 异物等进入咽喉深处。 中国发明专利说明书 "单腔双囊定位气管导管", 授权公告号 CN2770684Y, 授权公告日 2006年 4月 12日, 其技术方案的要点是,气管导管的后端连有连接 管,前端带有套囊,套囊通过套囊导管与封闭阀相连接,在套囊的尾侧端带有定位 套囊,定位套囊通过套囊导管与封闭阀相连接。 其优点: 套囊的设计方便准确定位。 不足之处: 无法阻挡口腔内血液、 分泌物、 异物等进入咽喉深处。 目前, 医疗器械市场亟待开发一种具有大球囊的双囊气管插管, 以实现对患 者口腔的封闭, 进而防止口腔内血液、 分泌物、 异物等进入咽喉深处。 对于硅橡 胶材料来说大球囊的成型十分困难, 因而阻碍了双囊气管插管的发展。 发明内容
本发明的目的, 是为临床治疗和外科手术提供一种安全有效的双囊气管插 管, 该双囊气管插管通过大球囊使气管插管准确的固定在患者喉部, 并防止手术 过程中的血液、 分泌物、异物等进入气道或食道。 医生可通过压力指示器检测充 气量和充气压力, 提高了治疗的操控性和安全性, 从而克服了现有技术的缺陷。 本发明为实现上述目的, 所采用的技术方案为: 一种双囊气管插管, 包括病人端接头, 小球囊, 加强通气管, 连接件, 气源 接头, 充气管和压力指示器, 其特征在于: 位于加强通气管上设有为与人体咽喉 部相适应的近似椭圆形的大球囊, 所述大球囊的结构由 a部件和 b部件构成,其 中 b部件的结构形式设计有两种不同形式的结构:一种为一体结构形式的 b部件, 另一种为由 c部件和 d部件共同粘接组成的 b部件。 所述 a部件, 其一端设有一圈凹槽, 并与 b部件前端开口处衔接平顺, 并 用粘合剂密闭粘接为一体。 所述大球囊, 其直径设计为 5cm〜10cm。 所述大球囊, 其材质为医用硅橡胶。 有益效果 本发明的有益效果: 1、 由于设计一种具有大球囊的双囊气管插管, 因而实 现对患者口腔的封闭, 进而防止口腔内血液、 分泌物、 异物等进入咽喉深处。 2、 通过大球囊使气管插管准确的固定在患者喉部, 并防止手术过程中的血液、分泌 物、 异物等进入气道或食道。 3、 操作人员通过压力指示器检测充气量和充气压 力, 提高了治疗的操控性和安全性。 附图说明 图 1为本发明的双囊气管插管的结构示意图;
