Effect of Needle-free Jet Injection of Insulin on Glucose Control and Injection Feelings in Type 1 Diabetic Patients

Plain-language summary

People with type 1 diabetes need long-term insulin injections. However, needles may cause discomfort or provoke anxiety if the patient has needle phobia, factors that contribute to poor compliance with insulin, especially in younger patients. Use of needle-free technology has been proposed as a strategy to mitigate these problems. There have been few studies on the efficacy of needle-free syringes for patients with type 1 diabetes. To determine the efficacy of needle-free injection of insulin in its patient population, people with type 1 diabetes, we conduct a pilot study to assess glycemic control and injection experience of patients. For the comparator device, we used an insulin pen. The primary objective is to explore whether needle-free syringes are more beneficial to control blood glucose than insulin pens of type 1 diabetes, which the blood sugar fluctuates significantly. The secondary objective is to evaluate the experience and safety of insulin administration by the needle-free injection.
