一种呼吸机管路延长管的设计与应用

Design and application of an extension tube for ventilator pipeline

目前临床上常规使用的呼吸机管路延长管在实施开放式吸痰时需要断开延长管与气管导管的连接,在正压作用下就会导致呼吸机管路内含致病微生物的冷凝水喷溅,部分会形成气溶胶悬浮于空气中,污染空气,增加交叉感染及操作者受污染的风险,同时呼吸机会发出相应的报警声,造成噪音污染。基于以上因素,解放军总医院第八医学中心重症医学科与首都医科大学附属北京友谊医院重症医学科医护人员联合设计了一种呼吸机管路延长管,并获得了国家实用新型专利(专利号:ZL 202021476518.X)。该装置由主管路、第一管套、第二管套、阀体、控制杆及轴套等组成,既能有效避免空气污染,降低交叉感染的风险,同时又能减少噪音污染,降低噪音对患者及医务人员的负面影响。

At present,the extension tube of the ventilator,a long corrugated tube used in clinical practice,needs to be disconnected from the endotracheal tube when performing open sputum suction.Under positive pressure,the condensed water containing pathogenic microorganisms in the ventilator will be splashed.Some will form aerosol suspended in the air,pollute the air,increase the risk of cross-infection and operator pollution,while the ventilator will emit a corresponding alarm sound,resulting in noise pollution.Based on the above factors,a ventilator pipeline extension tube was designed by the medical staff of department of critical care medicine of the Eighth Medical Center of People's Liberation Army General Hospital and department of critical care medicine of Beijing Friendship Hospital of Capital Medical University,and was obtained the National Utility Model Patent of China(ZL 202021476518.X).The device consists of the main pipe,first pipe sleeve,second pipe sleeve,valve body,joystick,axial sleeve,etc.,which can not only effectively avoid air pollution and reduce the risk of cross-infection,but also reduce noise pollution and the negative impact of loud noise on patients and medical staff.
