A kind of advanced immunization device for piglet pseudorabies in positive pig farm for medical use

Abstract

The invention relates to the technical field of porcine pseudorabies immunization, and discloses a device for advanced immunization against piglet pseudorabies in positive pig farms for medical use. Piston block, the surface of the piston block is fixedly connected with a pull rod, the inside of the pull rod is slidingly connected with a dilution rod, the inside of the piston block is fixedly connected with a negative pressure film, the bottom of the negative pressure film is movably connected with a rotating shaft, and the compression spring loses tension to pull the negative pressure film. The pressure film returns to its original state, and the rotating shaft rotates in the opposite direction, that is, the steering wheel moves on the surface of the rotating shaft toward the direction close to the needle. It penetrates into the piglet's body, but under the resistance of the pressure, it slowly moves downward, and injects the diluted medicinal liquid inside the shell into the piglet's body, thereby achieving the effect of stabilizing the injection pressure.

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
