Abstract:

Objective To explore the application value and effect of infrared thermometer in temperature monitoring of post-sterilization.Methods By using the infrared thermometer to test the cooling influencing factors,the time required for the cooling of the five types of sterilization packages,and the relationship between the cooling temperature and the wet package to obtain the reference data,and finally compare the incidence of wet packets and clinical satisfaction before and after the actual application of it.Results The difference in cooling rate between different placement floors,different packaging materials,different contents,different weight and volume of surgical bags after sterilization and unloading was statistically significant（P<0.05）. The time difference between the five types of sterilization bags cooled to room temperature was statistically significant（P<0.05）. The incidence of wet packs in cotton-packed surgical instruments at different cooling temperatures was statistically significant（P<0.05）. The difference in the incidence of wet packs before and after the application of the infrared thermometer was statistically significant（P<0.05）. The difference of times the sterilizer’s hand touching the sterilization package was statistically significant（P<0.05）.Conclusion Through the application of infrared thermometer for temperature monitoring,it can provide objective and accurate judgment for the migration and distribution of articles after sterilization,it also can effectively reduce the occurrence of wet packets and the risk of frequent exposure to pollution,so it has good application value and effect.

摘要：

目的 探讨红外测温仪在灭菌后物品冷却温度监测中的应用价值及效果。方法 通过灭菌后物品冷却速度影响实验、常见5类灭菌包冷却时间实验及不同冷却温度与湿包发生关系实验,获取红外测温仪在灭菌后物品冷却温度监测中的参考数据,同时比较红外测温仪实际应用前后的效果。结果 不同摆放层、不同包装材料、不同包内容物、不同重量与体积的手术包经灭菌卸载后的冷却速度以及常见5类灭菌包冷却至室温所需的时间各不相同,差异有统计学意义（P<0.05）,经棉布包装的大件手术器械包,在不同冷却温度下湿包发生率不同,差异有统计学意义（P<0.05）。红外测温仪应用前后,湿包发生率以及消毒员在灭菌包冷却期间手接触灭菌包的平均次数比较,差异有统计学意义（P<0.05）。结论红外测温仪能为灭菌后物品的移行和发放提供客观准确的参考数据,实际应用后可减少湿包发生率,降低频繁接触污染的风险。
