Development of Negative Pressure Vehicle for Sampling and Transporting Animal Pathogen

Objective To develop a negative pressure vehicle for sampling and transporting the animal pathogen.As a vehicle for sampling and transporting the suspicious animal pathogen on the spot where serious animal epidemic is suspected to be breaking out,many factors have been considered in the process of designing,such as the protection for personnel and environment.Methods The vehicle owned IVECO A36 chassis.On the basis of it,the structure of carriage and the different area were designed.The apparatuses for protecting,sampling,preservation and transporting were fixed out in the carriage.Special measurement were made to seal the carriage.The negative pressure was keeping by the exhaust-and-purify equipment.The temperature was controlled by using the air condition and heating.Results Ten items of measurement were taken for the vehicle.The pressure was stable in the range of-20 Pa to-50 Pa.Other parameters could reach the demand of designing.Conclusion The negative pressure vehicle is a new one for protecting the animal epidemic in our nation.It is shown that this vehicle can satisfies with the requirements of safety operation and rapid-and-safe transportation of sample.
