摘要:
为探究电热手套在低温环境下的御寒能力及其对医护人员户外采样时手部灵活性的影响，利用气候室提供的-20 ℃低温环境，对穿戴不同手套的受试者进行手部皮肤温度变化和抓取试验，并记录抓取试验中受试者手部主观热感。研究结果表明：在-20 ℃的低温环境下，与受试者手部初始平均温度相比，30 min内受试者穿戴加热状态的电热手套时手部皮肤平均温度提高7.275 ℃，穿戴医用采样手套时手部皮肤平均温度降低21.425 ℃；与医用采样手套相比，电热手套能够有效减小低温对手部灵活性的影响。从室温到低温环境，20 min内受试者穿戴电热手套时的工效提高4.3%，对手部灵活性的影响率从常温时的42.1%降至低温时的39.6%；穿戴医用采样手套时的工效下降19.2%。综合受试者手部主观热感，所研制的电热手套可在低温环境中长时间保证手部工作的灵活性。研究结果可为医护人员户外采样用电热手套的研制提供参考。
Abstract:
To explore the cold-resistant ability of electrically heated gloves in low-temperature environment and its influence on the hand dexterity of medical staff during outdoor sampling,the -20 ℃ low-temperature environment provided by the climate chamber was used to conduct the hand skin temperature change and grasping tests of subjects wearing different gloves,and the subjective thermal sensation of subjects’ hands in the grasping test was recorded.The results show that in the low-temperature environment of -20 ℃,compared with the initial temperature,the average hand skin temperature of subjects wearing the electrically heated electric gloves increased by 7.275 ℃ in heating status and decreased by 21.425 ℃ when weating the medical sampling gloves within 30 minutes.Compared with the medical sampling gloves,the electrically heated gloves can effectively reduce the influence of low-temperature on the hand dexterity.From room temperature to low-temperature environment,the work efficiency of subjects wearing electrically heated gloves increases by 4.3% within 20 minutes,and the influence rate on hand dexterity drops from 42.1% at normal temperature to 39.6% at low-temperature.When wearing the medical sampling gloves,the work efficiency drops by 19.2%.Comprehensively considering the subjective thermal sensation of the subjects’ hands,the developed electrically heated gloves can ensure the dexterity of hands working in the low-temperature environment for a long time.The research results can provide reference for the development of electrically heated gloves for outdoor sampling of medical staff.
