Medical-purpose advanced immunization apparatus for pseudorabies inpiglets in pseudorabies-positive pig farms

Abstract

The invention relates to the technical field of immunization against pseudorabies in pigs, and discloses a medical-purpose advanced immunization apparatus for pseudorabies inpiglets in pseudorabies-positive pig farms. The medical-purpose advanced immunization apparatus for pseudorabies inthe piglets in the pseudorabies-positive pig farms comprises a shell; a needle is fixedly connected with a surface of the shell; a piston block is movably connected with the interior of the shell; a pull rod is fixedly connected with a surface of the piston block; a dilution rod is in sliding connection with the interior of the pull rod; a negative-pressure film is fixedly connected with the interior of the piston block; and a rotating shaft is movablyconnected with the bottom of the negative-pressure film. When a compression spring loses tension so as to pull the negative-pressure film back to an original state and allowthe rotating shaft to reversely rotate, a steering wheel moves towards a directionclose to the needle on a surface of the rotating shaft, and a return spring moves slowly down under the action of a rotating force of the steering wheel and elasticity of the return spring itself; and the needle, which is already inserted into the body of a piglet, also moves slowly down against the pressure so as to have diluted drug liquid in the shell injected into the body of the piglet. Therefore, the effect of stable injection pressure is achieved.

Description

technical field [0001] The invention relates to the technical field of porcine pseudorabies immunity, in particular to a device for advanced immunity against pseudorabies for piglets in positive pig farms. Background technique [0002] Porcine pseudorabies is an acute infectious disease of pigs caused by porcine pseudorabies virus. In pig farms, pseudorabies virus is transmitted to healthy pigs mainly through the detoxification of infected pigs. In addition, staff and utensils contaminated by pseudorabies virus are spreading plays an important role in. [0003] Medical personnel have developed a porcine pseudorabies vaccine for porcine pseudorabies. For the vaccination, a syringe is often used to suck the diluted medicinal solution into the tube, and then inoculate it in the piglets. [0004] Although this kind of syringe can complete the vaccination work, it needs to be mixed with the liquid medicine before it can be used, and the exposure of the liquid medicine to the air...

AI Technical Summary

Problems solved by technology

[0004] Although this kind of syringe can complete the vaccination work, it needs to be mixed with the liquid medicine before it can be used, and the exposure of the liquid medicine to the air will increase the risk of infection, and because most pigs are raised in captivity, the number of piglets is large. Only relying on medical personnel with medical knowledge to dilute the medicinal solution for vaccination requires a lot of labor and takes a long time. In addition, when existing farmers vaccinate piglets, they cannot grasp the strength of the injection, and if they are not careful, it will be difficult for them to vaccinate. It will cause secondary damage to piglets, so a medically positive piglet pseudorabies advanced immune device came into being
