说 明 书
带侧孔的箭头形气管导管
一、 所属技术领域
本发明涉及一种前端为箭头形、前端口径为 5-6. 5麗、带有一个侧孔的不同内径气管导管。 二、 背景技术
目前， 在国内外麻醉科广泛采用的气管导管的前端是斜面侧孔式气管导管， 气管导管的 前端斜面是为了适应声门的 " 1 "字形裂隙 （全麻肌松下声带松弛后并非一定是 " 1 "字形）， 使导管更容易通过声门。 但实际运用过程中我们发现， 在困难气管插管时， 选择越细的气管 导管， 插管的成功率越高， 由于气管导管前端的斜面比较大， 往往比较容易受阻于声门， 使 得插管困难。 反复暴力插管很容易导致喉头水肿、 通气困难直至病人窒息。 这是气管插管困 难时病人死亡的最常见原因。 在困难气管插管时， 无论是使用纤维支气管镜辅助插管还是使 用插管探条辅助插管， 当纤维支气管镜或探条被成功插入气管后， 经常出现的情形是送管困 难！ 原因是当纤维支气管镜或探条的前部与气管导管套入部分成角时， 气管导管前段的斜面 遇到会厌或声带等阻碍时， 常常受阻！ 勉强送管则造成插管损伤、 纤维支气管镜损伤、 插管 困难等。为此，本人设计箭头侧孔式气管导管，导管的最前面为箭头形，开口处内径为 5- 6. 5画 (为了适用外径为 5瞧的插管探条及外径为 4. 5腿、 6. 0醒以下的纤维支气管镜的镜杆） ，目的 是能通过吸痰管、 插管探条、 纤维支气管镜等， 一方面箭头侧孔式气管导管的前端能部分通 气， 另一方面由侧孔通气， 二者共同承担机械通气的功能。 本导管的优点是前端为箭头形， 更容易通过声门， 可减少插管对喉头的损伤， 当用纤维支气管镜或探条处理困难插管时， 箭 头侧孔式气管导管的前端可 "紧紧"抱住纤维支气管镜或插管探条， 不至于损伤声带或会厌， 可显著提高插管的成功率。
三、 发明内容
为了克服现有的气管导管前端为斜面形， 通过声门时一旦受阻容易造成喉头损伤、 在用 纤维支气管镜或插管探条辅助气管插管以及逆行气管插管时气管导管的前端容易受阻， 导致 插管有一定的失败率， 本人设计本新型气管导管， 前端为箭头形， 可避免导管对喉头的损伤， 在用纤 支气管镜、 插管探条辅助插管或逆行气管插管时， 送管更加容易， 插管的成功率将 大大提高。
本发明解决其技术问题所采用的技术方案是： 气管导管其他部分与目前常用的普通导管 无异， 只是导管的前端设计为箭头形， 开口口径为 5- 6. 5mm, 除满足部分潮气量通过外， 还能 满足通过普通吸痰管、 纤维支气管镜、 插管探条等通过。 与不同型号的气管道相适应， 箭头 侧孔式气管导管的前端箭头长为 1- 4cm， 带有一侧孔， 为椭圆形， 面积等于导管中间部分的内 截面积，使得部分潮气量可从此处通过进出气道。箭头侧孔式气管导管的前端内径为 5- 6. 5mm, 加上面积等于导管内截面积的侧孔通气吸痰均不会受到影响。
本发明的有益效果是， 可以尽可能减少导管前端的截面积， 减少导管与喉头的接触面积， 导管的前端圆钝， 因此减少导管对喉头的损伤。 而普通气管导管的前端为一斜面， 除非导管 前端的斜面直接对准了声门裂隙， 否则在插管受阻时插管医生用暴力推进导管则造成了导管 前端对喉头的切割。
四、 附图说明
下面结合附图和实施例对本发明进一步说明。
图 1是本发明的原理图。
图中 1.箭头， 2.侧孔， 3.导管体。
五、 具体实施方式 箭头侧孔式气管导管插管的麻醉方法与一般气管插管方法相同。 临床上通常使用的气管 导管内径为 5. 5議、 6. 0mm, 6. 5讓、 7. 0mm、 7. 5mm、 8. 0mm, 8. 5mm, 因此本设计的气管导管体 的内径也与上述一致， 在图 1中， 所不同的仅仅是导管的前端为箭头形。 箭头处导管开口的内 径是 5- 6. 5皿， 目的是让吸痰管、 气管插管探条、 纤维支气管镜能顺利通过。 箭头侧孔式气管 导管对于一般病人的插管方法与通常的插管一样， 对估计有困难气管插管时， 先把气管插管 探条插入气管内， 再把气管导管套入插管探条， 送管， 箭头侧孔式气管导管的前端可 "紧紧 抱住"探条， 进入声门的导管箭头由细变粗渐渐进入气管， 可顺利通过声门。 纤维支气管镜 辅助插管时可先把纤维支气管镜的镜杆套入箭头侧孔式气管导管， 先插入纤维支气管镜再送 管， 同样， 箭头侧孔式气管导管的前端可 "紧紧抱住"纤维支气管镜， 渐渐进入气管内。
