医疗用品的棉质包布经不同处理后性能的比较

COMPARISON OF PROPERTIES OF COTTON CLOTH FOR PACKING MEDICAL ARTICLES AFTER DIFFERENT METHODS OF TREATMENT

对纯棉包布经不同方法处理后的性能进行比较。以肉眼观察颜色，对其所包医疗用品，在压力蒸汽灭菌后存放中作细菌污染检测。结果，用蒸汽煮沸洗涤的包布，在反复压力蒸汽灭菌后，仍纯白、柔软、吸水性与透气性良好，存放 １４ ｄ包内物品未被细菌污染；用热水浸泡洗涤者次之，存放 １４ ｄ， ９７％包内物品未被细菌污染；用冷水常规洗涤者变黄、僵硬、吸水性与透气性差，存放 １４ ｄ，仅 ８０％包内物品无菌。

The properties of pure cotton packing cloth treated with different methods were compared. Its color was observed by naked eye and bacterial contamination of the medical articles packed by it was examined after autoclaving and storing. The results indicated that the packing cloth treated with steam boiling and washing and repeated autoclaving still kept white, soft, good water-absorbency and air-permeability, and the articles packed with it were not contaminated by bacteria after storing for 14 days. The cloth treated with hot water immersion and washing showed properties inferior to those of the former and 97% of the articles packed with it were not contaminated by bacteria after storing for 14 days. The cloth treated with conventional cold water washing became yellow in color, stiff and showed poor water-absorbency and air-permeability, and only 80% of the articles packed with it were sterile after storing for 14 days.
