A simple time-cycled device uses an oscillating, fluidic, bistable element to control the high-pressure oxygen, supply to the ejector of a ventilating bronchoscope. Both manual and automatic modes of function are available, and inflation pressure and respiratory rate are controlled. Its construction is simple, the cost is low and the number of components is small.
一种简单的时间循环装置使用一个振荡的、流体的、双稳态元件来控制向通气支气管镜喷射器供应的高压氧气。它具备手动和自动两种功能模式,且可控制充气压力和呼吸频率。其结构简单,成本低,部件数量少。
