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CO2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.%For improving the oxygen utilization rate of the positive pressure oxygen respirator and making the human body breathe more comfortable,an intelligent positive pressure oxygen respirator was designed,which can automatically regulate the oxygen supply according to the requirement of the human body.In this paper,the working principle of the intelligent oxygen breathing system and the intelligent oxygen supply device was described,the breathing resistance of the intelligent oxygen respirator,the residual pressure in the oxygen cylinder,the temperature of the inhaust and the CO2 concentration in the inhaust were all tested.The tests showed that the breathing resistance difference of the intelligent oxygen respirator became smaller,the breathing resistance curve became much smoother,the oxygen consumption of the respirator was less and its service time was much longer.
