【摘要】：為提高正壓氧氣呼吸器的氧氣利用率,使人體呼吸更舒適,設(shè)計(jì)了一種智能供氧裝置,其供氧流量可隨人體所需自動(dòng)調(diào)節(jié)。介紹了智能供氧呼吸系統(tǒng)及智能供氧裝置的工作原理,試驗(yàn)檢測了使用智能供氧裝置的呼吸器的呼吸阻力、氣瓶余壓、吸氣溫度和吸氣CO_2濃度。試驗(yàn)表明,智能供氧呼吸系統(tǒng)呼吸阻力差變小、呼吸阻力曲線更平滑,呼吸器的氧氣消耗量更小、使用時(shí)間更長。
[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.
