Description
Technical Field
The invention relates to the technical field of sterilization devices, in particular to a direct-discharge vacuum sterilization box for precise instrument sterilization.
Background
With the increase of population and the development of urbanization, the population density of the world is greatly improved. The potential broad spread and contamination of various bacteria is a significant challenge to today's public health care industry. In addition, with the rapid development of public health care industry, various sophisticated instruments and devices are being widely used in disease diagnosis and treatment places such as hospitals and clinics. In the fields of pharmacy, food, light industry and the like, disinfection and sterilization of specific articles or products are often required. The above situation puts higher demands on sterilization, disinfection and other aseptic technologies.
Facing the challenge of how to rapidly and effectively sterilize bacteria, a variety of methods have been proposed and used for treatment. Generally, sterilization methods can be classified into three major categories, physical methods, chemical methods and biological methods: 1) the physical method comprises a thermal method and a non-thermal method, the physical sterilization method can accurately control the dosage, and the sterilization is stably carried out on the premise of not polluting the natural environment; 2) the chemical method inactivates bacteria by exerting the synergistic effect of the disinfectant, has strong sterilizing capability, wide application range, convenient use and no need of special equipment; 3) the biological disinfection method is a disinfection method for killing or removing pathogenic microorganisms in the external environment by utilizing animals, plants, microorganisms and metabolites thereof, and is mainly used for disinfection treatment of the surfaces of water, soil and organisms.
Although the traditional sterilization method has reliable sterilization effect and wide application range, the treatment methods have obvious defects aiming at more precise instruments and mainly comprise the following three aspects: 1) the wet and hot method in the physical method is the most widely used sterilization method at present, but the method is mainly used for sterilizing heat-resistant and moisture-resistant articles and is not suitable for articles which are not high-heat-resistant and moisture-resistant, such as syringes, cotton fabrics and the like; 2) the dry heat method has the defects of high sterilization temperature and action time, easy damage to articles, uneven temperature, possibility of polluting sterilized articles by circulating dry hot air and the like; 3) chemical methods all suffer from various disadvantages including toxicity, irritation, corrosiveness and instability.
Among the numerous sterilization techniques, the low temperature plasma technique stands out. The technology has the advantages of reliable sterilization effect, quick action, cleanness without residue and the like, and is applied to sterilization in a plurality of fields at present.
The low-temperature plasma is generated after various physical and chemical reactions occur in the generation process: electromagnetic fields, heat, ultraviolet light, charged particles, excited particles, metastable particles, and the like. The active components contain high energy potential enough to destroy chemical bonds, can start a series of physical and chemical reactions, and can interact with structures such as microorganisms and human cells to cause cell level effects such as inactivation and structural damage. Wherein, ultraviolet ray can kill cells by mechanisms such as direct radiation and damage cell macromolecules (protein, DNA and the like); the active oxygen-containing group can directly destroy the cell structure from the outside and penetrate into the cell to generate oxidation effect, and the active nitrogen-containing group can induce the generation of the active oxygen-containing group in the organism. When the oxidation pressure in microorganisms and human cells is too high, the cell structure can be completely collapsed; the synergistic effect of the charged particles and the electric field also contributes to the inactivation of bacteria.
Developers have developed a variety of sterilization devices for different sterilization needs. The existing apparatuses may be classified into a high pressure steam sterilization apparatus, an ultrasonic ultraviolet sterilization apparatus, and a plasma source according to sterilization methods.
1) The high-pressure steam sterilizing device is mainly used for sterilizing heat-resistant and moisture-resistant articles, such as medicines and aqueous solutions thereof, glass, porcelain and metal products, rubber plugs, membrane filters, cotton fabrics and the like. Since the steam penetration is enhanced under a higher pressure, the sterilization effect can be greatly improved by increasing the temperature. As shown in the devices disclosed in the patents CN111888491A, CN211863372U and CN211797795U, the steam sterilizer can satisfy the effective sterilization of most medical instruments.
2) The ultrasonic method is used for sterilization by using a high-frequency and high-intensity ultrasonic wave source with sterilization value, and the microwave method and the ultraviolet method are used for sterilization by using the penetrability of electromagnetic waves and light waves, so that the sterilization effect with low temperature, low energy consumption, rapidness and no selectivity is realized. As disclosed in CN211272540U, CN208462861U and other patents, the sterilization device can effectively inactivate bacteria by combining ultrasonic wave and microwave with ultraviolet lamp.
3) The plasma method performs sterilization through the synergistic effect of physical and chemical reactions such as electromagnetic field, heat, ultraviolet rays, charged particles, excited-state particles, metastable-state particles and the like, and has the advantages of reliable sterilization effect, quick effect, cleanness without residue and the like. Patent CN211587653U discloses a hydrogen peroxide low-temperature plasma sterilization device, which utilizes the strong oxidation of hydrogen peroxide reagent in combination with the plasma recombination to effectively sterilize instruments. The plasma sterilizing and disinfecting cabinets disclosed in patents CN210932886U and CN211214540U use a gas flow module and an atomization module to blow plasma to the surface of an object to be treated for sterilization.
The disadvantages of the above sterilization apparatus are as follows:
1) the autoclaving method is the most common sterilization method in the medical instrument sterilization, but with the appearance of more and more heat-sensitive materials, the single autoclaving method cannot meet the needs of people, and the surface of part of advanced precise medical equipment is irreversibly damaged due to the action of water vapor, high temperature, high pressure and the like, so that the service life of the equipment is shortened.
2) The radiation methods such as ultraviolet radiation, electron beam radiation and the like have the defects of poor penetrating power, extremely easy occurrence of the phenomenon of light reactivation, easy breakage of cell DNA molecules, cell mutation and the like. And requires a large investment and specialized equipment to generate the radiation. In addition, radiation therapy requires safety precautions to be performed in strict compliance with the standard dose.
3) For the chemical agent method, the medical disinfectant solution is 75% alcohol, hydrogen peroxide and iodophor, and the chemical disinfectant such as ozone, sodium hypochlorite and chlorine is adopted in life. Research shows that the chemical substances and the byproducts thereof have irritation, and the residue of the chemical agents can pose certain threat to human health.
4) Most of the existing plasma sources are combined with strong oxidizing agents such as hydrogen peroxide for sterilization, certain chemical residues exist, and the strong oxidizing agents can influence the service life of equipment. In addition, the existing plasma source has the defects of needing an additional airflow module and an atomization module, being more complicated in operation process, not ideal in treatment uniformity degree and the like.
In summary, aiming at the sterilization requirement of precision instruments, and combining the advantages of the atmospheric pressure low temperature plasma biomedical application, it is an urgent need of those skilled in the art to provide a direct discharge type vacuum sterilization device for sterilizing precision instruments.
