摘　　要：呼吸机是目前临床上应用较多的辅助机械通气设备,在治疗低氧血症等方面具有重要作用。呼吸机相关性肺炎(VAP)是机械通气患者常见的一种特殊类型的院内感染的肺实质性炎症,可以导致患者病死率增加,严重影响患者预后。呼吸机管路接头管理不规范以及呼吸机管路内喷溅而出的含菌冷凝水形成的气溶胶污染空气进而导致交叉感染,则是VAP发生的重要原因。现有呼吸机管路接头帽可起到避污的效果,但临床应用依从性不高。基于以上因素,广西中医药大学公共卫生与管理学院等单位师生和医护人员共同设计了一种呼吸机管路接头避污及防空气污染装置,并获得了国家实用新型专利(专利号:ZL 202021361981.X)。该装置由模肺、罩体、悬挂部和束口部等组成,使用方法简单,可适用于有创呼吸机以及无创呼吸机管路接头的避污,从而减少患者VAP的发生以及医护人员的职业暴露。Ventilators are currently the most commonly used auxiliary mechanical ventilation equipment in clinical practice,and play an important role in the treatment of hypoxemia.Ventilator-associated pneumonia(VAP)is a special type of pulmonary parenchymal inflammation of nosocomial infection in patients with mechanical ventilation,which leads the increase of mortality and affects the prognosis of patients.The non-standard management of ventilator pipeline joints and the aerosol formed by bacterial condensate splashed from ventilator pipeline pollute the air,resulting in cross infection,which are the important reasons for VAP.The existing ventilator pipeline joint cap can achieve the effect of preventing pollution,but the clinical application compliance is not high.Based on the above factors,teachers,students and medical staff of the School of Public Health and Management,Guangxi University of Chinese Medicine and other units have designed a device for preventing pollution and air pollution of the ventilator pipeline joint,and obtained the national utility model patent of China(ZL 202021361981.X).The device is composed of a model lung,a mask body,a suspension part and a beam mouth part,etc.The use method is simple,and can be applied to the pollution avoidance of invasive ventilator and non-invasive ventilator pipeline joints,to reduce the occurrence of VAP in patients and the occupational exposure of medical staff.
