1611 Study on Division Injection for Needle-free Injector Systems
Details
This paper describes influence of gap and equivalent mass upon characteristic of jet in Needle-free injection. For the needle-free injection used for the diabetic treatment to have the problem such as fill the drug to the syringe at each use though it injected two or more times a day, and to solve this, how the jet condition such as the impact gap influenced with the injection force at the rise time was examined. The discharge characteristics of the liquid jet were measured using a test instrument. The experiments reveal that an injection force depends on gap and spring force, and rise time depends on gap.
