用于cpca呼吸机的新生儿护理用呼吸管路固定器设计

Design of respiratory pipeline fixator for neonatal nursing of CPCA ventilator

cpca呼吸机管路固定器设计过程中,由于管路接触性分析方法的差异,实际应用中位移发生概率较高。因此,提出用于cpca呼吸机的新生儿护理用呼吸管路固定器设计。利用有限元分析方法求解固定器接触性问题,获取呼吸管路固定参数。结合多种固定装置,设计固定器结构模型。考虑到舒适性和相容性,选取硅橡胶作为固定器主要制作材料,按照新生儿所需护理形状和尺寸,完成呼吸管路固定器的制作。临床应用结果表明:所设计的呼吸机管道固定器的应用,使得管道位移发生概率降低了28%、32%。

During the design of CPCA ventilator pipeline holder, due to the difference of contact analysis methods in pipeline fixing parameters, the probability of displacement is high. Therefore, the design of respiratory pipeline holder for neonatal nursing of CPCA ventilator is proposed. The contact problem of fixator is analyzed by finite element analysis method, and the fixation parameters of respiratory pipeline are obtained. Combined with a variety of fixtures, the structural model of the fixture is designed. Considering the comfort and compatibility, silicone rubber was selected as the main manufacturing material of the fixator, and the respiratory pipeline fixator was manufactured according to the nursing shape and size required by newborns. The clinical application results show that the application of the proposed ventilator pipe holder reduces the probability of pipe displacement by 28% and 32%.
