Description

Long-handle injection gun for veterinary use

Technical Field

The application relates to the technical field of injection guns, in particular to a long-handle injection gun for veterinarians.

Background

Syringes are a common medical device. As early as the 15 th century, katini, italian, proposed the principle of a syringe, which consists of a barrel with a small hole at the front end and a plunger stem fitted thereto, for injecting a small amount of liquid or the like into or out of an area inaccessible to other methods, and which is primarily used for withdrawing or injecting gas or liquid with a needle, and the process of withdrawing or injecting gas or liquid with a needle is called injection, and liquid or gas is sucked in through the small hole at the front end of the barrel when the stem is withdrawn, and liquid or gas is pushed out when the stem is pushed in.

As disclosed in the chinese patent: a veterinary long-handled injection gun, publication No.: CN213489531U, which is a connecting spring connected with a sealing cover and arranged on a piston rod, when a user pushes a push block and makes the push block push the piston rod, a connecting block and a piston block under stress, when a liquid medicine in an injection tube is pushed to the injection tube and the injection needle enters into an animal body, the connecting block after moving drives the connecting spring to stretch, the user loosens the thrust on the push block after the injection is finished, and then the connecting block which is not limited by the thrust drives the piston rod to return to the original position under the action of retraction after the connecting spring is stretched, so that the purpose that the user can finish the return of the piston rod to the original position without manually pulling the piston rod is realized, but because the volume of each animal is different, the dosage is different when the medicine is injected, the injection gun can not quantify the size of the animal, generally depends on experience judgment, and easily causes excessive possibility to occur, thus leading to poor treatment effect, and even cause damage to the animal.
