ABSTRACT
Objective To investigate the safety of novopen needle after repeated uses in order to save the expenses of patients. Methods 60 diabetic patients undergoing insulin therapy were random-ized into the common temperature group and the refrigerated storage group. The novopens were stored at common temperature in a clean and dry place, while the refrigerated storage group was stored in cold clos-et of a refrigerator. Oropharyngeal swab bacterial culture was used to compare the incidence of infection in two groups on the first, third, fifth, and seventh days. Results There was no bacterial growth in either storage condition. Conclusions The novopen needle can be repeatedly used in clinic work.But they must be used individually. Storage at common temperature or in a refrigerater can reach the same effect.
