What is plasma sterilizer?

Plasma sterilizer definition

plasma-sterilizer
Plasma sterilizer is a scientific instrument that can sterilize metal instruments, which mainly uses bipolar plasma electrostatic field to decompose and break negatively charged bacteria, polarize and adsorb dust, and then combine with drug-impregnated activated carbon, electrostatic network, photocatalytic devices and other components for secondary sterilization and filtration, after sterilization treatment of a large amount of fast circulating clean air to keep the controlled environment at the standard of sterile clean room.

Application of plasma sterilizer

Plasma sterilizer as a disinfection sterilization technology introduced into the field of disinfection, its research and application have been rapidly developed, with hydrogen peroxide low-temperature plasma sterilization technology being applied most successfully. In addition, the use of plasma technology for indoor air purification, and disinfection also has applications.

Sterilization of medical devices by plasma sterilizer
Low-temperature plasma sterilization technology is a new low-temperature sterilization technology after glutaraldehyde, ethylene oxide, and other sterilization technologies. Plasma sterilization is widely used for sterilization of medical appliances that are not resistant to moisture and high temperatures, such as various precision instruments and endoscopes. Especially with the wide application of minimally invasive surgery, hospitals need a large number of lumpectomy equipment, at this time, low-temperature plasma sterilization can effectively reduce or avoid damage to high-temperature sensitive medical appliances, and often become a common sterilization method in hospitals. In addition, it can also be used for the sterilization of sanitary materials, food, and tableware. The application of this technology will certainly play a great role in promoting the development of medical, health, food, and biological engineering technology.

Plasma sterilizer for purifying microorganisms in the air
With the emergence of viruses, the biosafety of air is increasingly important. Hospitals are vulnerable to infected people and pathogenic bacteria concentration, respiratory diseases caused by airborne and easy cross-infection. Applying plasma technology to the field of air purification and disinfection (plasma air purification disinfector), the air is purified and sterilized by using a cutting-edge corona discharge to form a plasma cloud. The elimination rate of Staphylococcus aureus in the air is 95 % in 30 minutes at room temperature and 99.84 % in 60 minutes for Bacillus subtilis black variant bacilli, which is suitable for continuous air disinfection under human conditions.
At present, plasma air purification disinfector has been widely used in clean rooms of factories, hospital operating rooms, isolation wards, and other places with high cleanliness requirements, as well as office buildings, trains, automobiles, and other public places for air disinfection and purification.

Plasma sterilizer working principle

hydrogen-peroxide-sterilizer
The following is about the working principle of the plasma sterilizer
First of all, the plasma in the plasma sterilizer is an ionized gas-like substance composed of positive and negative ions produced by the ionization of atoms and atomic groups after partial deprivation of electrons.
The plasma contains reactive oxygen atoms, and oxygen molecules and the radiation generated by the plasma will damage bacterial cell membranes, DNA, and proteins by the following mechanisms:
The role of reactive groups
Plasma contains a large number of active oxygen ions, high-energy free radicals and other components, it is very easy and bacteria, mold and bacterium, viruses in the protein and nucleic acid material oxidation reaction and denaturation, so that all kinds of microbial death.
High-speed particle breakdown effect
After the sterilization experiment, through the electron microscope to observe the role of plasma after the bacterial body and virus particles image, showing a lot of holes, which is generated by the high kinetic energy of the electron and ion breakdown etching effect.
Role of UV light
In the process of excitation of hydrogen peroxide to form a plasma, accompanied by part of the ultraviolet ray, this high-energy ultraviolet photon are absorbed by microorganisms or viruses in the protein, resulting in its molecular denaturation and inactivation.

Advantages of using plasma sterilizer

Plasma sterilizer is a new type of disinfection technology. Compared to traditional UV circulating air disinfectors, plasma air disinfectors have the following advantages.
1. Highly effective sterilization
The disinfection effect is very strong, and the action time is short.

2. Environmental protection
Plasma sterilization works continuously and does not produce ultraviolet light, or ozone, to avoid pollution of the environment.

3. Efficient degradation
While disinfecting the air, can also degrade the toxic and harmful gases in the air. A test report shows that the degradation rate within 24 hours is 91% for formaldehyde, 93% for benzene, 78% for ammonia, and 96% for xylene.
Low energy consumption.
Its start-up power is 1/3 of the UV disinfection machine.
Long service life. Under normal use, its design life of 15 years, while the UV disinfection machine is about 5 years.

Types of plasma sterilizer

The main types of plasma sterilizers are as follows,

1. Gas plasma sterilizer

2. Hydrogen peroxide plasma sterilizer

gas-plasma-sterilization
The principle of hydrogen peroxide plasma sterilizer is mainly to sterilize with hydrogen peroxide. Hydrogen peroxide is vaporized by the low-temperature plasma sterilization device, and under the vacuum condition of the sterilization bin, the vaporized hydrogen peroxide is evenly diffused to the whole space inside the chamber and can penetrate the sterilization package. Hydrogen peroxide itself has a strong bactericidal effect and can kill some microorganisms on the surface of the treated items in the process of hydrogen peroxide diffusion.

3. Low-temperature plasma sterilizer

low-temperature-sterilizer
Low-temperature plasma sterilizer is formed in a sterilization chamber formed by a sealed container, and according to the preset conditions and specific equipment, a glow discharge is generated by excitation to form a low-temperature plasma. The H2O2 plasma contains active components such as hydroxyl radical HO-, peroxyl radical HO2-, excited H2O2, active oxygen atom O-activated hydrogen atom H-, etc. These active ions and abundant ultraviolet light have high thermokinetic energy, thus greatly improving the effectiveness of the action with microbial proteins and nucleic acid substances, which can cause microorganisms to die in a very short time and achieve the purpose of sterilizing instruments. The purpose of sterilization of instruments is achieved.

6. Packaging and loading of sterilized items must be following specifications.

7. Pay attention to hand hygiene, wash hands under the seven-step hand washing method, and use clean hands to touch sterilized items and sterilized items.

8. The plasma sterilizer should be maintained once a week for minor maintenance and once a month for major maintenance.

How to maintain plasma sterilizer?

To avoid frequent failures of the low-temperature plasma sterilizer during use, proper maintenance and care must be taken.
1. Wipe the surface of the low-temperature plasma sterilizer door and instrument, and clean the floor of the sterilization room at least once.

2. Clean the impurities in the filter at the discharge port inside the sterilizer to avoid the impurities from entering the exhaust pipe during the operation of the sterilizer.

3. Check whether the sterilizer door seal is flat, intact, and free from dislodgement and breakage. Check the touch screen; observe whether there is leakage of steam, water, and other media pipelines and valve parts; observe whether the sterilizer operation indicator is intact; once the above parts are found to have problems, the sterilizer should not be used and be used after maintenance and repair.

4. Clean the exterior of the low-temperature plasma sterilizer to avoid the accumulation of dust, which will shorten the service life of the air filter. Contact between components and water should be avoided, and water should be dried before powering on. Check whether the sockets and connectors of each connection are loose, and those that are loose should be inserted tightly.

5. The safety valve, pressure gauge, and temperature gauge of the sterilizer should be inspected annually, and the inspection results should be recorded and kept. The air filter should also be replaced regularly.
