Markable continuous veterinary drug injector

Abstract

The invention provides a markable continuous veterinary drug injector. The injector comprises an injection tube, a piston rod and a handle, wherein the handle is used for pushing and pulling the piston rod to telescope in the injection tube; the handle comprises a front handle and a rear handle hinged to each other through a rotating pin, the end, away from the rotating pin, of the front handle isconnected to the injection tube, the end, away from the rotating pin, of the rear handle is connected to the end, protruding out from the injection tube, of the piston rod, a first marking assembly is arranged on the handle, the marking assembly comprises a marking pen, a marking pen clamping part and a marking pen fixing part, the marking pen clamping part comprises a sleeve pipe and two connecting pieces, the connecting pieces are arranged in parallel and symmetrically arranged on the outer side wall of the sleeve pipe, and the ends, away from the sleeve pipe, of the connecting pieces are connected to the rotating pin through the marking pen fixing part. According to the markable continuous veterinary drug injector, the marking pen can be perfectly combined with the handle, and the presence of the marking pen does not hinder an operator from pushing and pulling the handle to make the piston rod repeatedly move in the injection tube, and injection and marking are achieved simultaneously.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a markable continuous veterinary medicine injector. Background technique [0002] Veterinary syringes are often used to inject drugs or vaccines for animals, but when the number of breeding animals is large, it is necessary to mark the animals that have been injected with drugs. The existing syringes usually only have the function of injection, and the marking often requires the cooperation of other people. One person injects, Another person marks, low work efficiency and troublesome operation. Some veterinary syringes are also integrated with markers, but most of them are set on the injection barrel. When using, the center of gravity is tilted forward, which is difficult to control. If it is arranged on the handle, the presence of the marker during injection will affect the operator to push and pull the handle to make the piston rod move repeatedly in the injection barrel, which increases ...
