临床上高频喷射呼吸机HFJV已被用于多种病人的辅助呼吸。它虽然可以提供满意的氧合,但在清除CO_2方面不够理想。对此作者设计了高频双路喷射呼吸机HFTWJV,通过动物实验就通气效果和特性与HFJV进行比较。实验用新型HFTWJV,由电脑控制两个特定的螺旋管阀(A和B),通过阀门间断性地开关,使来自高压气源的气流产生喷射气流脉冲。吸气时 High-frequency jet ventilator clinical HFJV has been used for a variety of patient assisted breathing. Although it can provide satisfactory oxygenation, it is not ideal for removing CO 2. The author designed a high-frequency dual-jet ventilator HFTWJV, compared with HFJV by animal experiments on the ventilation effect and characteristics. Experimental With the new HFTWJV, two specific solenoid valves (A and B) are controlled by the computer and intermittently switched by the valve to generate a jet of jet impulses from the gas stream of the high-pressure gas source.
