Current high speed projectile beam is used in many different fields, and a variety of branches. Because the beam is catapulted high speed can be adapted to a range of tasks. Whether it's engineering or medical This emphasis on research studies, drug delivery feature with a high-speed projectile beam is created from the main shock, which has a spring, etc. are known as Needle-free liquid jet injection to generate voltage limits of a projectile at high speed. Use the method with the driver of a moving object is a shock and then press call this principle that the main shock and press driven by Impact method to study the features of the device, from the unforgiving trunk injection experiments were designed to create a high speed projectile beam using Springs, etc. are by will meet.Education characteristics of the beam is catapulted from the speed of the projectile and beam pressure shocks rocketed beam that can be applied in real life, and is it appropriate? The experimental devices are designed in size 0.3 mm and 0.5 mm nozzle with 0.2 ml capacity experiment by changing the springs and has a value of k varies according to the size of the wire since 0.71 0.64, Bridwell, 0.90 0.80, 1.24 mm, 1.07, found that the beam is catapulted out of the nozzle is injected at the speed of a projectile beam is in the range of 1.15-270 m/s, and 10-45 pressure MPa pressure and speed bumps, of beam catapulted suitable for drug delivery through the skin. The results from this study can confirm that to create a shock by a fling with springs, etc. are suitable to be used in drug delivery through the skin and can also develop the kit appropriately and effectively.
