We have produced a compact, lightweight oxygen concentrator, using a newly-developed polymer of poly [1-(trimethylsilyl)-1-propyne] with a performance, i.e. oxygen permeability, of 61 x 10 cm3 (STP) cm/cm2 s cmHg, which is 17 times higher than that of the membrane material of conventional concentrators. The oxygen and nitrogen selectivity was 1.80. The dimensions of the apparatus are 325 x 180 x 150 mm and it weighs about 4.0 kg. It is actuated by a battery (DC 12 V, 5.6 Ah), with a 100 V AC source and a car battery (12 V) source also available. The power consumption is 70 W. The generated oxygen concentration is about 30%, and the maximum flow rate is 41/min. Applying 10 samples of various chronic pulmonary diseases to the subject, the suction of oxygen from the apparatus in the patients' rest state was conducted. An increase in the PaO2, from an average of 59.1 Torr before the suction to an average of 68.5 Torr after the suction, together with easing of breathing, was indicated. The usefulness of this apparatus for supplying portable oxygen-treatment to patients with chronic respiratory disease is shown.
我们制造了一种紧凑、轻便的氧气浓缩器，它使用新开发的聚[1-(三甲基甲硅烷基)-1-丙炔]聚合物，其性能即透氧率为61×10 cm³(标准温度和压力) cm/cm² s cmHg，比传统浓缩器的膜材料高17倍。氧氮选择性为1.80。该装置尺寸为325×180×150 mm，重约4.0 kg。它由电池(直流12 V，5.6 Ah)驱动，也可使用100 V交流电源和汽车电池(12 V)电源。功耗为70 W。产生的氧气浓度约为30%，最大流速为4 l/min。对10名患有各种慢性肺部疾病的受试者进行了测试，在患者休息状态下从该装置吸氧。结果表明，吸氧后动脉血氧分压(PaO₂)从吸氧前的平均59.1 Torr升至吸氧后的平均68.5 Torr，同时呼吸也有所缓解。这表明该装置对慢性呼吸道疾病患者提供便携式氧气治疗是有用的。
