瓶内胰岛素反复抽吸后安全使用时间的研究

目的：研究胰岛素开瓶后安全使用的时间，方法：根据每日抽吸次数分为5组，即抽吸1针／d,2针/d，3针／d，4针／d，5针／d，于开瓶后的第5天开始做细菌培养，直至第35天结束，共采样91次，结果：低温下瓶内胰岛素抽吸5针／d于第10天，4针/d于第16天，3针／d于第20天，2针／d于第25天，1针／d于第35天，细菌培养结果显示阳性，结论：随着每日抽吸次数的增加，安全使用时间缩短。

study on the satety service time of opened to recurrent syring extraction insulin

Objective: To explore the safety service time of the opened insulin.Method: According to the extractive time of the insulin every day,theqroups were as tollows:extractive one time a day,two times a day,thnee times a day,four times a day and fine times a day.The baeterial culture was performed from 5th day to 35th day after insulin opened.The sampliing was 91 times.Result: The result of baeterial culture of opened insulin at low temperature is positiver eaction in follows:the five times a day at 10th day,the four times a day at 16th day,the three times a day at 20th day,the two times a day at 25th day,the one time a day at 35th day,Conclusion: As extractive times increase every day,the sayety sevvice time of opened insulin is shorten.
