【摘要】：目的比較幾種醫(yī)用包裝材料阻菌率,不同洗滌次數(shù)的棉布失重率、撕裂強(qiáng)度及耐磨性的差異。方法依據(jù)無菌醫(yī)療器械包裝試驗(yàn)方法,對棉布、無紡布、一次性過濾紙三種包裝材料進(jìn)行阻菌率測試,采用棉布失重試驗(yàn)、抗拉力試驗(yàn)、耐磨性試驗(yàn),對不同洗滌次數(shù)棉布的失重率、撕裂強(qiáng)度及耐磨性進(jìn)行測試。結(jié)果透氣包裝材料微生物屏障分等試驗(yàn)中,雙層新棉布、雙層舊棉布、一次性過濾紙和無紡布平均阻菌率分別為62.15%、31.39%、82.04%和89.71%;棉布經(jīng)洗滌30次后失重率下降1.22%,撕裂強(qiáng)度下降6.70%,經(jīng)織物平磨儀測試均沒有起毛起球。結(jié)論阻菌效果排名依次為無紡布、一次性過濾紙、雙層棉布。棉布經(jīng)洗滌30次后,失重率和撕裂強(qiáng)度有所下降,阻菌效果較新棉布差。
[Abstract]:Objective to compare the bacteriostasis rate, weight loss rate, tear strength and wear resistance of several kinds of medical packaging materials. Methods according to the packing test method of sterile medical instruments, the bacteriostasis rate of cotton cloth, non-woven cloth and disposable filter paper were tested. The cotton cloth weightlessness test, tensile test and wear resistance test were used. The weight loss rate, tear strength and wear resistance of cotton cloth with different washing times were tested. Results in the microbial barrier classification test of breathable packaging materials, double layer new cotton cloth, double layer old cotton cloth, The average bacteriostasis rates of disposable filter paper and non-woven cloth were 62.15% and 89.71%, respectively, the weight loss rate of cotton cloth decreased 1.22% and the tear strength decreased 6.70% after washing for 30 times. Conclusion the rank of bacteriostatic effect is non-woven cloth, one-time filter paper and double-layer cotton cloth. After washing for 30 times, the weight loss rate and tear strength of cotton cloth decreased, and the bacteriostasis effect was worse than that of new cotton cloth.
