摘　　要：目的研制一种能自动挤压控制潮气量的简易呼吸器(Bag-Valve-Mask,BVM),并探讨其在人体模型上的应用效果。方法在原有BVM的基础上设计一种能自动挤压控制潮气量的BVM,并选取36名重庆医科大学附属第一医院的医护人员应用该仪器,分别在该仪器潮气量400、500、600 mL及常规人工挤压BVM的4种条件下,采取单人EC手法在人体模型上各面罩通气30 min,比较各组的通气成功率和通气频率。结果3组仪器在同一时间点的通气成功率均显著高于人工组(P<0.001);人工组在同一时间点的通气频率均显著高于3组仪器组(P<0.001),且人工组在各时间点的通气频率显著高于12次/min。结论自动挤压控制潮气量的BVM是一种自动且操作简便、可辅助BVM通气的新型医疗器械装置,在人体模型上初步应用效果明显,一定程度上可提高BVM的通气质量,保证其安全性和有效性。Objective To develop a bag-valve-mask(BVM)which can automatically squeeze to control the tidal volume,and to explore the effect of its application on mannequins.Methods Based on the original BVM,a BVM which can automatically squeeze and control tidal volume was designed,and 36 medical staffs from The First Affiliated Hospital of Chongqing Medical University were selected to apply this instrument,under the 4 conditions of tidal volume of 400,500,600 mL and conventional artificial squeeze breathing apparatus,a single EC technique was used to ventilate each mask on the mannequin for 30 min,and the ventilation success rate and ventilation frequency of each group were compared.Results The ventilation success rate at the same time point of the 3 groups of instruments were significantly higher than that of the manual group(P<0.001);the ventilation frequency at the same time point of the manual group was significantly higher than that of the 3 groups of instruments(P<0.001),and the ventilation frequency at all time points of the manual group was significantly higher than that of 12 times/min.Conclusion The BVM with dynamic squeeze control of tidal volume is an automatic,easy to operate new medical device and can assist the ventilation of the BVM.The initial application on the mannequin has obvious effect,which improves the ventilation quality of the simple ventilator to a certain extent,ensures its safety and effectiveness.
