a medicine syringe

Abstract

The invention belongs to the field of syringes, and in particular relates to a liquid medicine injector, which includes a syringe, an injection head, a piston mechanism, a piston A, a hose, a needle sleeve, a needle tube, and a slide plug, wherein the injection head on the syringe is connected to the syringe through the hose. The needle cover is connected, and the needle cover has a needle tube; compared with the traditional simple modified syringe that simply connects the needle head and the syringe with a flexible tube, the present invention realizes it through the cooperation of the sliding plug with a communication groove, the piston mechanism and the piston A Draw the medicinal liquid into the injection cylinder and inject the medicinal liquid into the livestock and poultry body; in the present invention, due to the cooperation of the slide plug and the piston mechanism, the syringe can inject all the medicinal liquid in the syringe and the flexible pipe into the livestock and poultry body without residue; After the injection, there will be a phenomenon that the hose remains more liquid because the piston cannot reach it, thereby avoiding the waste of liquid medicine and reducing the cost of vaccination of livestock and poultry.

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
