The invention relates to the technical fields of medical cosmetic apparatuses and
medicine injection, and in particular to a jet micro-needle injection
system. The jet micro-needle injection
system comprises a
medicine tube, a
piston and a push rod, wherein both the
piston and the push rod are arranged in the
medicine tube; the
piston is connected to the front end of the push rod, and the piston gets into sealed
sliding contact with the inner wall of the medicine tube; and a soluble micro-needle is arranged in an
injection port at the front end of the medicine tube. When the injection
system is used for conducting injection, the soluble micro-needle is pierced into
skin to form a small transdermal hole in the
skin firstly, then medicine liquid in the medicine liquid, under push force of the push rod which is pushed, forms a medicine
jet flow, and finally, medicines, in the form of the
jet flow, are dissolved by virtue of the soluble micro-needle and are applied subcutaneous tissues from the opened
small hole. The injection system is
safer to use, and the injection system can conduct transdermal injection at a relatively low jet speed.
