Title:
NEEDLELESS SYRINGE
Document Type and Number:
WIPO Patent Application WO/2021/112485
Kind Code:
A1
Abstract:
The present invention allows a moving magnetic body to collide with a piston so as to move the piston forward, and thus can inject a drug at a higher speed by using less energy. A needleless syringe according to the present invention can cause the piston for pressurizing and injecting a drug to repeatedly reciprocate forward and backward so as to enable a predetermined drug to be repeatedly injected at a high speed, and thus enables, in the fields of skin care and the like, multiple injections, rather than a single injection, during a single procedure into broader areas of the skin such as the face. In addition, a user can automatically and repeatedly inject the predetermined drug at a high speed without the necessity of separate loading. Furthermore, the needleless syringe according to the present invention includes a rebound offset part for offsetting rebound generated when the piston moves forward and backward, and thus has more improved convenience of use.
