Thermal conditions in operating rooms are mainly dictated by the need to meet the safety/comfort requirements of the patient. However, the accuracy of performed surgical procedures depends on the surgeon and others members of medical team. Hence, their comfort sensation should be also factored in. The study sought to find out how thermal sensations of people working in surgical clothing can be modified through a local change in air velocity and temperature around the user. A series of tests was carried out with a thermal manikin to make an accurate assessment of the effectiveness of this type of equipment. The tests included changes of the ambient temperature, supply air temperature and air velocity. The operational efficiency was assessed on the basis of the equivalent temperature index (teq). Results show that the final result of teq was mostly determined by air velocity rather than the supply air temperature.

局部温度和风速变化对手术服使用者的热感的影响

手术室的热工条件主要取决于满足患者安全/舒适要求的需要。但是,执行的外科手术程序的准确性取决于外科医生和医疗团队的其他成员。因此,他们的舒适感也应考虑在内。该研究试图找出如何通过用户周围的空气速度和温度的局部变化来改变手术服工作人员的热感。用热暖人体模型进行了一系列测试,以准确评估此类设备的有效性。测试包括环境温度,送风温度和空气速度的变化。的操作效率进行了评估等效温度指标的基础上(当量)。结果表明,t eq的最终结果主要由风速而不是送风温度决定。
