某型救生钟生命支持系统性能人体试验

Investigation of life support system of a type of rescue bell in human beings

目的:验证生命支持系统改换装后的总体性能。方法:救生钟在常压下进行10人8 h试验。结果:整个试验过程中,钟内CO2浓度始终未超过指标上限1.5%,钟内O2浓度基本保持稳定,均在21%左右。结论:生命支持系统改换装后,能满足技战指标要求,工作性能稳定。

Objective： To verify the ensemble performance of the life support system after repackaging. Methods： An experiment of rescue bell had been carried out in ten men subjects for eight hours. Results： During experiment, the concentration of CO2 in the bell had not exceeded 1.5 % of top limit of index all along, and that of O2 in the bell had kept about 21%. Conelnsion： The ensemble performance of the life support system is stable and can provide a safe living condition.
