The ‘syringe with needle 23G’, which is widely used in general internal medicine department, has a needle diameter of 0.635mm (needle for drawing blood, 18G=1.27mm) while the size of nozzle hole from which the drug in our injector is shot is very small and fine, ranging from 0.23 to 0.25mm.

 

While conventional needle injector uses a needle to secure the path of drug penetration into the skin and slowly pushes the drug into the body by using the force of the fingers,

 

"Jet injector" employs high-pressure jet of liquid medication to penetrate the skin and deliver medication under the skin by sticking fine nozzle holes to the skin. That is, the liquid medication functions as a needle in a moment.

"Jet injector" penetrates each layer of the skin and goes straight to a certain depth. When it reaches the barrier of the skin, it delivers the medication in a way that spreads out horizontally and evenly in an instant along the texture of the tissue.

 

This allows you to “deliver medication to the desired penetration layer more evenly and faster than needle injector without the fear of needles.

​

This kind of needle-free drug delivery method is defined as “Jet injector” academically in oversea.
