Randomized Controlled Trial Comparative StudyUsability of a microtapered needle (TN3305) for insulin treatment in japanese patients with diabetes mellitus: a comparative clinical study with a standard thin wall needle.
We evaluated the clinical usability of a microtapered needle (TN3305, "Needle T," Terumo Corp., Tokyo, Japan) by comparing it with a standard needle (Micro-Fine +, 31 gauge, 5 mm, thin wall, "Needle B," Nippon Becton Dickinson Co., Ltd., Tokyo) in a multicenter study. ⋯ The preferences and VAS scores suggested that Needle T caused less pain than Needle B. The incidence of adverse events and safety were equivalent for both needles. We believe that usability of Needle T by patients for self-injection is better.
