目的:研制一种呼吸机湿化液滴入接头,以解决湿化液滞留、管道漏气、呼吸机管道固定等问题.方法:取一次性输液延长管,留取注射器端约10 cm;另在呼吸机管道原装配套的L型接头侧壁上打一个孔,孔的内径大小与输液延长管直径外径相等.经此孔置入输液延长管注射器端,置入深度4～6 cm.在输液延长管与小孔衔接处用502胶及短小止血带密封固定.结果:呼吸机湿化液滴入接头固定牢靠,能与输液器(输液泵)、输液延长管(微量泵)紧密衔接,可灵活改变方向,避免了湿化液无效蓄积,吸痰方便,湿化效果好,提高了机械通气治疗效果.结论:新型呼吸机湿化液滴入接头制作简单,取材方便,减少并发症,缩短人工气道持续时间,提高危重患者救治成功率,值得临床推广.%Objective To develop a humidification fluid dropping joint for the breathing machine to solve the problems in humidification fluid retension,pipeline leakage,pipeline fixation and etc.Methods A Infusion extension tube was involved in with 10 cm length left at the injector end.A hole was made at the side wall of the L-shaped joint of the breathing machine,whose internal diameter equaled to the external diameter of the extension tube.The extension tube was put into the joint through the hole,and the depth of imbedded tube was within 4 and 6 cm.Sealing and fixation at the connection between the tube and hole were executed with 502 glue and short tourniquet.Results The humidification fluid dropping joint could be connected with infusion apparatus of the pump or the infusion extension tube of the micro pump,which behaved well in eliminating accumulated humidification fluid,sputum suction,humidification and facilitating mechanical ventilation.Conclusion The joint developed gains advantages in easy manufacture,reducing complications and increasing the dependence on artificial airway,and thus is worthy promoting clinically.
