Sterilizing device for biosafety cabinet

Abstract

The invention discloses a sterilizing device for a biosafety cabinet. The device comprises a shell. An objective table is arranged on the shell, a liquid suction needle head is arranged on the objective table; a cold evaporator, a blower and a metering pump which provides a suction power source are also arranged in the shell; a liquid inlet and a liquid return port are formed in one end of the cold evaporator, a spray nozzle is arranged at the other end, the liquid suction needle head is connected to a liquid inlet pipe, the liquid inlet pipe is connected to a liquid inlet, the metering pump is arranged between the cold evaporator and a reagent bottle, one end of the metering pump is connected to the liquid return port thorough a first liquid return pipe while the other end of the meteringpump is connected to the liquid suction needle head through a second liquid return pipe, the cold evaporator is provided with an air inlet and an air outlet, an air outlet pipe is arranged at the output end of the blower, the air outlet pipe is connected to the air inlet, and the spray nozzle is arranged close to the air outlet. The sterilizing device atomizes a sterilizing reagent fully and doesnot damage the original chemical structure of the sterilizing reagent, and the sterilizing reagent can be fully diffused to a-to-be-sterilized environment.

Description

technical field [0001] The invention relates to the technical field of sterilization equipment, in particular to a biological safety cabinet sterilization device. Background technique [0002] Since microorganisms widely exist in the surrounding environment, and some of them are pathogenic microorganisms, from the perspective of preventing infection or avoiding product contamination, aseptic operations must be strictly implemented in medical work or high-precision production and scientific research work. The environment is disinfected and sterilized to ensure the normal progress of medical treatment and scientific research. Disinfection and sterilization mainly use sterilization equipment to hinder the main metabolism of microorganisms through physical and chemical factors, or denature and solidify bacterial proteins, or destroy their genetic material, resulting in the death of microorganisms. When using sterilization equipment, it is necessary to fully atomize the reagents...

AI Technical Summary

Problems solved by technology

When using sterilization equipment, it is necessary to fully atomize the reagents used for sterilization and then evaporate them, and spread the evaporated reagents to the environment or surface that needs to be sterilized. However, the existing sterilization devices generally use Heat sterilization reagents are used to achieve the purpose of atomization and evaporation, but the original chemical structure of the sterilization reagents will be destroyed after heating, resulting in unsatisfactory sterilization effects or complete failure of the sterilization reagents

Moreover, the atomization of the existing sterilization device is insufficient and the atomized sterilization reagent cannot be fully sprayed onto the environment or surface to be sterilized, resulting in poor sterilization effect of the reagent, and at the same time, it is impossible to effectively monitor the concentration of the reagent. The staff in the atomization state cannot replace the new sterilization reagent in time or delay the replacement
