摘要

尽管从一次性手术衣过渡到可重复使用手术衣前景广阔,但成功实施仍面临挑战。本研究对可重复使用手术衣的触觉和热生理舒适性进行了调查,并将其与一次性手术衣进行了比较。使用织物触感测试仪对表面粗糙度、压缩、热通量和材料硬度等参数进行了测试。此外,还对手术服的水蒸气渗透性和静电荷进行了评估。通过测量受试者穿戴时的温度和相对湿度(RH),对手术服的热生理舒适性进行了评估。使用 iButton 传感器和热像仪监测皮肤温度,并分析任务期间对心率的影响。每次测试后,参与者都会通过问卷提供主观反馈。结果表明,与一次性织物相比,可重复使用的长袍质地更光滑,减少了对皮肤的摩擦,热传导效果更好。与一次性织物相比,它们还具有更高的水蒸气渗透性。穿戴试验显示,一次性和可重复使用长袍的舒适度差异很小。在进行活动时,体温升高会导致相对湿度下降,但这种上升并不会对受试者的舒适度产生不利影响,这一点已通过心率和问卷调查数据得到验证。从舒适度的角度来看,从一次性手术衣转换到可重复使用手术衣不会有任何弊端,这意味着只要物流和成本能够得到控制,医院就应该能够转换手术衣。

Evaluation of Tactile and Thermophysiological Comfort in Reusable Surgical Gowns Compared to Disposable Gowns
Though the transition from disposable to reusable surgical gowns holds substantial promise, successful implementation faces challenges. This study investigated tactile and thermophysiological comfort in surgical reusable gowns, comparing them with their disposable counterparts. Parameters such as surface roughness, compression, heat flux, and material rigidity were tested using a Fabric Touch Tester. Additionally, the water vapour permeability and static charge of the gowns were assessed. Thermophysiological comfort of the gowns was evaluated by measuring the temperature and relative humidity (RH) on test subjects during wear trials where they were engaged in an activity that mimics a surgeon’s performance. Skin temperature was monitored using iButton sensors and a thermal camera, and the impact on heart rate during the task was analysed. Following each test, participants provided subjective feedback through a questionnaire. The results indicated that reusable gowns boasted a smoother texture, translating to reduced friction on the skin and better heat transfer compared to the disposable fabrics, as indicated using FTT. They also exhibited higher water vapour permeability compared to their disposable counterparts. The wear trials revealed minimal differences in comfort between disposable and reusable gowns. While performing the activity, an increase in body temperature led to decreased RH, yet this rise did not adversely affect subject comfort, as validated using heart rate and questionnaire survey data. From a comfort point of view, switching from disposable to reusable gowns would not have drawbacks, meaning hospitals should be able to switch provided logistics and costs can be managed.
