【摘要】:为提高正压氧气呼吸器的氧气利用率,使人体呼吸更舒适,设计了一种智能供氧装置,其供氧流量可随人体所需自动调节。介绍了智能供氧呼吸系统及智能供氧装置的工作原理,试验检测了使用智能供氧装置的呼吸器的呼吸阻力、气瓶余压、吸气温度和吸气CO_2浓度。试验表明,智能供氧呼吸系统呼吸阻力差变小、呼吸阻力曲线更平滑,呼吸器的氧气消耗量更小、使用时间更长。
[Abstract]:In order to improve the oxygen utilization rate of positive pressure oxygen respirator and make human breathing more comfortable, an intelligent oxygen supply device was designed. This paper introduces the working principle of intelligent oxygen supply respiratory system and intelligent oxygen supply device, and tests the breathing resistance and residual pressure of the respirator using intelligent oxygen supply device. The experimental results show that the respiratory resistance difference of intelligent oxygen supply respiratory system becomes smaller, the respiratory resistance curve is smoother, the oxygen consumption of respirator is smaller and the use time is longer.
