Problems solved by technology

[0003] At present, the lyophilized rabies vaccine for humans is inoculated with Vero cells with a fixed strain of rabies virus. After culturing, the virus liquid is harvested, and the virus is inactivated, concentrated, purified, and made by adding an appropriate amount of gelatin and sucrose protective agent to freeze-dry. Centrifugal purification by centrifuge, this method requires frequent treatment of filter residues, affecting production efficiency

Abstract

The invention discloses a rabies vaccine preparation device which comprises a vertically-arranged shell, the shell is cylindrical, a feeding pipe and a discharging pipe are fixedly connected to the side wall of the shell, the feeding pipe is close to the top of the shell, the discharging pipe is close to the bottom of the shell, a cover plate is fixedly connected to the top of the shell, and a driving motor is fixedly connected to the top of the cover plate. A rotating shaft of the driving motor is rotationally connected with the cover plate and penetrates through the cover plate, a centrifugal assembly used for centrifugation is arranged in the shell, and the centrifugal assembly and the motor are matched with a conveying mechanism used for conveying raw materials. The device has the beneficial effects that the centrifugal assembly is matched with the conveying mechanism, residues and filtrate are centrifugally separated through the centrifugal assembly, meanwhile, the residues are discharged through the conveying mechanism, and the production efficiency is improved; the tool bits are arranged in the conveying assembly to crush cakes in the raw materials, the centrifugal efficiency is further improved, and the utilization rate of the raw materials is increased.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a preparation device for rabies vaccine. Background technique [0002] Rabies is an acute infectious disease caused by rabies virus. It is a zoonosis between humans and animals. It is more common in carnivorous animals such as dogs, wolves, and cats. Most people are infected by being bitten by sick animals. The clinical manifestations are unique fear of water, wind, and throat. Muscle spasms, progressive paralysis, etc. Rabies in my country is mainly transmitted by dogs. At present, there is no effective treatment for rabies. The fatality rate after human rabies is almost 100%. Patients usually die of breathing or circulation within 3 to 6 days. Therefore, preventive measures should be strengthened. Rabies vaccine is the rabies vaccine and anti-rabies serum that are inoculated after being bitten by animals to prevent infection with rabies. The rabies vaccine is one of the current ...
