Description
同轴双套回路呼吸器
技术领域
本实用新型涉及到一种麻醉机、呼吸机使用，尤其涉及到一种同轴双套呼 吸lHj路。
背景技术
在传统的全身麻醉手术中，用于病人的麻醉机呼吸回路管子是分离的，即 一根吸入氧气， 一根呼出二氧化碳。由于氧气是低温保存的，所以在吸入氧气 时因氧气温度偏低而刺激呼吸道粘膜。全身麻醉时间一长，易损害病人的呼吸 道粘膜，造成手术后病人呼吸功能下降，排痰及排其它分泌物困难。其次，因 二根并列的塑管占用空间大，特别是医生在对头，面部进行手术时感到极为不 便，往往因此影响了手术视野质量和效果。
实用新型内容
本实用新型的目的在于提供一种同轴双套呼吸回路，其主要由一 T型接 头、 一出气管接头、 一输氧管、 一外管、 一进出气管接头组成。
该T型接头包括一进氧气口、 一T型接头的内管、一T型接头的外管、 一出气口。该T型接头的进氧气口的一端套在麻醉机或呼吸机上，该T型接 头的内管连接于输氧管的一端，输氧管的另一端连接于进出气管接头的内管。 该外管的一端连接于进出气管接头的外壁，另一端连接于出气管接头的外壁。 该出气管接头的另一端连接于T型接头的外管的外壁。
该同轴双套回路呼吸器由二根管道合而为一，管道内径经过科学计算，可 适合不同肺活量病人。
本同轴双套回路呼吸器具有以下优点：
可科学计算通气道截面积，大大縮小了外形体积，增大手术中医生的视线 角度，方便头面部手术的操作，提高了医生的快速应变能力，确保手术质量。 输氧管道包在最内层，当接近体温的二氧化碳气体呼出后，围绕并温暖了
内部的输氧管道，使输氧管内的氧气温度提高，减少了由于氧气温度偏低而引 起对呼吸道的刺激。
同轴双套回路器重量轻，减小了对病人气管插管产生的下压重力，亦能防 止插管过深插入到单侧支气管而产生的损伤。
上述结构可应用于麻醉机，呼息机等相应的呼吸回路系列产品。
附图说明
图1是本实用新型一种同轴双套回路呼吸器的结构原理图。
图2是沿图1中的A-A方向的截面图。 具体实施方式
请参阅图1至图2， 一种同轴双套呼吸回路，其主要由一T型接头（1)、 一出气管接头（2)、 一输氧管（3)、 一外管（4)、 一进出气管接头（5)组成。
该T型接头（1)包括一进氧气口 （11)、 一T型接头的内管（12)、 一T 型接头的外管（13)、 一出气口 （14)。该T型接头（1)的进氧气口 （11)端 套在麻醉机或呼吸机上，该T型接头（1)的内管（12)连接于输氧管（3) 的一端，输氧管（3)的另一端连接于进出气管接头（5)的内管（51)。该外 管（4)的一端连接于进出气管接头（5)的外壁，另一端连接于出气管接头（2) 的外壁。该出气管接头（2)的另一端连接于T型接头（1)的外管（13)的外 壁。
首先将该T型接头（1)的进氧气口 （11)端套在麻醉机或呼吸机上，氧 气通过T型接头（1)的内管（12)进入到输氧管（3)，最后氧气到达进出气 管接头（5)供病人吸取。
病人吸入氧气后将吐出的二氧化碳经进出气管接头（5)进入到氧气管（3) 的外壁与外管（4)的内壁的通道中，再进入到T型接头（1)的外管（13)内， 最后通过T型接头（1)的出气口 （14)将二氧化碳排出。
因氧气在输出时有一定的压力，所以小于氧气压力的二氧化碳气体只能进 入到外管（4)的内壁通道中并经过T型接头（1)的出气口 （14)排出。在密 封的情况下，进气与出气各自形成流动。
