LENGTH-REDUCING SYRINGE DRIVING DEVICE

摘要

Disclosed herein is a length-reducing syringe driving device, the length-reducing syringe driving device wherein a drive for syringe device is installed at a syringe device (10), and pushes and drives a piston (12) equipped at an injection cartridge (11) which has a discharging outlet (13) at one dead end thereof.;The length-reducing syringe driving device (100) comprises: a rotation driving part (110) installed at one or more places at an outer sidewall surface at the other dead end of the injection cartridge (11); and a one-way bending member (120) provided to be contacted to the piston (12) at one dead end thereof, configured to be bended exclusively to one direction, and having a sidewall surface of a bending direction driven by the rotation driving part (110) and pushing the piston (12).;In the present invention, main elements of the invention are disposed at an outer sidewall surface of an injection cartridge and the entire length (L) of a driving device is remarkably reduced when having the same stroke. Therefore, it is to provide a syringe device which is convenient to be carried and to make syringe devices having many different embodiments possible.
