引言以往,国内医学实验室所用的功物人工呼吸机多为笨重而粗糙的“斯氏”呼吸机,这种呼吸机的缺点是,潮气量及呼吸频率的调节不方便,而且潮气输出精度不高(即机子的气体泄漏大),为了能改善这一落后面貌,我校于1977年底开始在研制“小儿人工呼吸机”的基础上,进行了“动物实验人工呼吸机”的研制工作。 INTRODUCTION In the past, the artificial respirator used in domestic medical laboratories was mostly a heavy and rough “Stiftung” ventilator. The disadvantage of this ventilator was that the adjustment of tidal volume and respiratory frequency was inconvenient, and the accuracy of tidal output was not. High (that is, the machine’s gas leak is large), in order to improve this backwardness, our school began to develop the “animal experiment artificial respirator” on the basis of the development of “pediatric artificial respirator” at the end of 1977.
