Safe high-precision vaccine continuous dosing/syringe

Abstract

The invention provides a safety high-precision vaccine continuous feeding / injection apparatus. The apparatus comprises an injecting gun, a liquid container, a dilution puncture tube, a dilution backflow tube, a three-way change-over valve and a plurality of check valves, the liquid container is mounted on the injecting gun, and a liquid outlet of the liquid container is communicated with a liquid inlet of an injecting pipeline of the injecting gun through one of the check valves. By coinciding of an injecting position passage of the three-way change-over valve and the injecting pipeline of the injecting gun, the three-way change-over valve is assembled on the injecting pipeline, a dilution position outlet is communicated with the dilution puncture tube, and one of the check valves is arranged on a communication pipeline. A puncture end of the dilution puncture tube is used for puncturing into a vaccine vial, and one end of the dilution backflow tube is communicated with the liquid container. By the three-way change-over valve, a dilution passage or an injection passage can be adjusted, and a closed dilution circuit is formed in a dilution process, so that dilution of vaccine lyophilized powder in a closed internal circulation system of the injecting gun and the liquid container is realized. In addition, the dilution process is free of single manual operation, and accordingly probability of virus infection of workers is avoided.

Description

technical field [0001] The invention relates to the technical field of vaccine injection equipment, in particular to a safe high-precision vaccine continuous administration / syringe. Background technique [0002] my country is a large country of livestock and poultry breeding. With the rapid development of animal husbandry, livestock and poultry diseases and epidemics are also emerging, especially the emergence of major animal diseases that are zoonotic, which directly brings great losses to the animal husbandry industry, and also brings great losses to people's health. Healthy living brings risks. Therefore, the country has formulated a plan for the prevention and control of major animal diseases. For these diseases, the national organization has developed different freeze-dried vaccines for effective epidemic prevention to ensure effective epidemic prevention and control, keep animal husbandry healthy, effective and sustainable, solve potential safety hazards, and improve pe...
