Liquid medicine injector

Abstract

The invention, which belongs to the field of injectors, particularly relates to a liquid medicine injector which comprises an injection cylinder, an injection head, a piston mechanism, a piston A, a hose, a needle sleeve, a needle tube and a sliding plug. The injection head on the injection cylinder is connected with the needle sleeve through the hose; and the needle tube is arranged on the needlesleeve. Compared with the traditional simply-modified syringe simply connecting a syringe needle and a syringe barrel through a hose, the provided liquid medicine injector has the following advantages: liquid medicine is sucked into the injection cylinder and inject the liquid medicine is injected into livestock and poultry bodies by cooperation of the sliding plug with a communicating groove, the piston mechanism and the piston A; because of cooperation of the sliding plug and the piston mechanism, the injector can completely inject liquid medicine in the injection cylinder and the hose intolivestock and poultry bodies in a residue-free manner; and the phenomenon that more liquid medicine remains in the hose because the piston cannot reach after injection is finished is avoided, so thatliquid medicine waste is avoided, and the livestock and poultry epidemic prevention injection cost is reduced.

Description

technical field [0001] The invention belongs to the field of syringes, in particular to a medicinal liquid syringe. Background technique [0002] The main purpose of livestock and poultry epidemic prevention work is to ensure that large-scale epidemic diseases do not occur in the process of rural livestock and poultry breeding, and to diagnose, treat, prevent and control major diseases of livestock and poultry. The work of livestock and poultry epidemic prevention is the basic guarantee for the prosperity of the rural livestock and poultry breeding industry, and it is also the basis for the development of the rural livestock and poultry breeding industry. [0003] Liquid medicine injection is an important part of livestock and poultry epidemic prevention. It injects medicine liquid into sick livestock and poultry through a syringe and treats livestock and poultry quickly and effectively; traditional medicine liquid injectors in the process of injecting livestock and poultry,...

AI Technical Summary

Problems solved by technology

[0003] Liquid medicine injection is an important part of livestock and poultry epidemic prevention. It injects medicine liquid into sick livestock and poultry through a syringe and treats livestock and poultry quickly and effectively; traditional medicine liquid injectors in the process of injecting livestock and poultry, livestock and poultry It is likely to struggle due to pain, which will lead to the inability to continue the injection work, and sometimes even the needles of the syringes will fall off or break due to the violent struggle of the livestock and poultry

In practical applications, in order to prevent the needle from the syringe from falling off or breaking, the epidemic prevention workers will separate the needle from the syringe, and use a hose to connect the two for injection; however, after the injection in this way, there will be More liquid medicine remains, which leads to the waste of liquid medicine and increases the cost of vaccination injection

[0004] Aiming at the above-mentioned problems of the traditional syringes such as falling off the needle and breaking the needle when the livestock and poultry are struggling, it is necessary to design a syringe that can prevent the needle from falling off and breaking the needle and avoid the residual liquid medicine in the hose used to connect the needle and the injection barrel
