基于质控数据的婴儿培养箱温度特性对比研究
|
摘要
目的对比分析A、B两个品牌婴儿培养箱的温度特性,并发掘它们在不同温度指标之间的差异,为临床使用及设备采购选型工作提供依据。方法选取10台均于2007年投入使用的两个品牌的婴儿培养箱,使用MATLAB对其2012年至2016年间的质控数据进行分析,主要分析两个品牌的温度偏差、温度波动度以及温度均匀度。另外,通过柯尔莫可洛夫-斯米洛夫检验分析升温时间和报警温度的概率分布,以估计其分布区间。结果通过对比发现B品牌的温度特性更好,升温时间更短更集中且断电保护温度更低。所以B品牌比A品牌具有更好的温度稳定性及使用安全性。结论在选型论证及招标采购时,选择B品牌培养箱更符合临床对设备质量的要求。
Objective By comparing and analyzing the temperature characteristics of A and B brands of infant incubators, we attempt to explore the differences between them in temperature indexes, and provide a basis for clinical use and equipment procurement selection. Methods We selected 10 infant incubators which were put into use in 2007, to analyze their quality control data from 2012 to 2016 using MATLAB. We mainly analyzed the temperature deviations, temperature ?uctuations, temperature uniformity of two brands. In addition, the probability distribution of the heating time and the alarm temperature was analyzed by the Kolmokov-Smiroff test to estimate the distribution interval. Results Comparing with the A brand, it was found that the B brand of infant incubators showed better temperature characteristics, with a shorter and more concentrated heating time and a lower power-off protection temperature. Therefore, the B brand had better temperature stability and safety than the A brand. Conclusion In the bidding procurement, the selection of the B brand incubators is more in line with the clinical requirements for equipment quality.
