Spring and piston, which allow, under pressure, quickly and evenly inject drugs under the skin through a hole with a diameter of 0.17 mm, which is two times smaller than the needle thickness for injection!
With the help of the energy of mechanical action, the spring and the special piston in the apparatus allow, under pressure, quickly but gently pushing the drug stream through a microscopic hole into the subcutaneous tissue.
