基于恒压加载的正压氧气呼吸器呼吸阻力分析

Breathing Resistance Analysis of Positive Pressure Oxygen Respirator Based on Constant Pressure Loading

摘要: 提出了气囊恒压加载式正压氧气呼吸器，对比测试了气囊恒压加载和弹簧加载的呼吸阻力。试验结果表明：气囊恒压加载产生的呼吸阻力比弹簧加载产生的小，并且其呼吸阻力波动幅值也比弹簧加载产生的小。当气囊载荷增大，呼吸量增大时，呼吸阻力增大；当气囊载荷减小，呼吸量减小时，呼吸阻力减小。

Abstract: This article proposes a balloon constant pressure-loaded positive pressure oxygen respirator and comparatively tests the breathing resistance value of balloon constant pressure-loaded respirators and spring-loaded respirators. The test results show that the breathing resistance value of balloon constant pressure-loaded respirators is lower and the amplitude of breathing resistance is smaller compared with spring-loaded respirators. When the load or the breathing capacity increased, the breathing resistance increased. When the load or the respiratory intensity reduced, the breathing resistance reduced.
