In order to solve the related technical problem that exists among the prior art, this application embodiment provides an external scale device suitable for pre-flush syringe, aims at solving current liquid medicine and is polluted the scheduling problem easily, realizes that children accurately use medicine, easy operation, reduce the effect of pollution risk. Referring to fig. 1-6, the syringe specifically comprises a handheld handle 100, a limiting rod 200 and a scale sleeve 300, wherein the handheld handle 100 is clamped on the syringe barrel, and the handheld handle 100 is located at the top end of the syringe barrel. When injecting liquid medicine into children, because the needle tubing is small, inconvenient medical personnel's centre gripping, so the top card of syringe cylinder has established handheld handle 100, and handheld handle 100 is pressed close to the both sides on syringe top and is equipped with the recess, can establish the card of syringe top in handheld handle 100, avoids the syringe to drop from handheld handle 100. And the shapes and sizes of the two sides of the hand-held handle 100 are fit with fingers, so that the medical staff can conveniently clamp the injector by using the hand-held handle 100.

The handle 100 is provided with a scale sleeve 300 extending downwards, the scale sleeve 300 is half wrapped on the syringe needle cylinder, and the handle 100 and the scale sleeve 300 are integrally formed. The scale sleeve 300 is made of transparent material, the liquid medicine in the syringe can be observed through the transparent scale sleeve 300, and the scale sleeve 300 is provided with scale marks 500, so that the volume of the liquid medicine in the syringe can be determined through the scale marks 500.
