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。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 in- creased. When the load or the respiratory intensity reduced, the breathing resistance reduced.
