Cold evaporation sterilization device

Abstract

The invention discloses a cold evaporation sterilization device which comprises a shell; an air outlet and an air return port are formed on the shell; a weighting platform, a cold evaporator, a fan and a metering pump are arranged in the shell; a reagent bottle and a recorder are arranged on the weighting platform; a liquid inlet and a liquid return port are formed on one end of the cold evaporator; a spray port is formed on the other end of the cold evaporator; the reagent bottle is connected with the liquid inlet through a liquid feeding pipe; the metering pump is arranged between the cold evaporator and the reagent bottle; one end of the metering pump is connected with the liquid return port through a first liquid return pipe while the other end is connected with the reagent bottle through a second liquid return pipe; an outer cover is arranged on the exterior of the cold evaporator; the outer cover comprises an air feeding port and an air exhausting port; the air exhausting port isconnected with the air outlet; the spray port is arranged close to the air exhausting port; an output shaft of the fan is connected with the air feeding port; an air return pipe is jointed between the fan and the air return port. The cold evaporation sterilization device is capable of atomizing drugs under the condition of constant temperature, spreading into a sterilization space and promoting sterilization effect.

Description

technical field [0001] The invention relates to the technical field of sterilization equipment, in particular to a cold evaporation 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 reagent and spray...

AI Technical Summary

Problems solved by technology

When using sterilization equipment, it is necessary to fully atomize the reagent and spray the atomized drug on the surface of the object to be sterilized. However, the existing sterilization device is not sufficiently atomized and cannot effectively detect the concentration of the drug. Use status, whether it is used up or the amount per unit time, these data can effectively feedback the sterilization effect, and record the parameters, making it possible to formulate better sterilization strategies and sterilization methods in the future; and the existing sterilization devices usually bring A certain degree of temperature rise, and in the field of biopharmaceuticals, most pharmaceuticals or reagents are very sensitive to temperature changes, and heating can easily lead to drug denaturation and affect the medicinal properties of pharmaceuticals
