摘　　要：目的探索在低温条件下乳糜血浆过滤的最适压力参数,同时通过改进实验方法提升乳糜血浆处理质量并提高过滤效率。方法分别比较30份重度乳糜血浆标本在常规制备环境压力下进行过滤和控制滤过膜压力差为0.5 bar的制备环境下进行过滤的滤过效果和滤过时间。结果2种不同制备压力下的重度乳糜血浆标本滤前、滤后吸光度相比均有统计学意义(P<0.05),均能达到预计过滤效果。控制滤过膜压力差为0.5 bar的制备环境下,过滤时间较快,且过滤效果较好,与常规制备环境压力下相比具有统计学意义(P<0.05)。结论通过对在低温条件下过滤乳糜血浆的最适压力参数的选择,提升了低温条件下乳糜血浆过滤的效率,提高了低温过滤技术的实用性和可靠性。Objective To explore the optimal pressure parameters for chyle plasma filtration under low-temperature conditions,and to improve the quality of chyle plasma treatment and filtration efficiency by improving experimental methods.Methods The filtration efficiency and filtration time of 30 severe chyle plasma samples under conventional preparation environment pressure and under preparation environment with a controlled filtration membrane pressure difference of 0.5 bar were compared.Results The absorbance of severe chyle plasma samples before and after filtration under two different preparation pressures was statistically significant(P<0.05),and both achieved the expected filtration effect.Under the preparation environment of controlling the pressure difference of the filtration membrane to 0.5 bar,the filtration was faster and with better effect,which was statistically significant compared to the conventional preparation environment pressure(P<0.05).Conclusion By selecting the optimal pressure parameters for filtering chyle plasma under low-temperature conditions,the efficiency of chyle plasma filtration under low-temperature conditions has been improved,and the practicality and reliability of low-temperature filtration technology have been enhanced.
