Hydrogen peroxide low temperature plasma sterilizer
With the rapid development of medical technology and high technology, more and more surgical instruments are used in surgery, and many surgical instruments cannot withstand high-temperature steam sterilization. Low-temperature sterilization technology solves the sterilization problem of heat-labile surgical instruments. Although ethylene oxide sterilization and glutaraldehyde immersion sterilization are also commonly used, this method of sterilization has a long sterilization cycle and is toxic. , Pollution of the environment and other shortcomings. The hydrogen peroxide plasma sterilizer has the advantages of low temperature, dryness, rapidness, and non-toxicity, and has been gradually used in some relatively large-scale medical institutions in recent years.
一. The principle and characteristics of sterilization
Principle of low temperature plasma
After high concentration (60%) hydrogen peroxide is injected into the sterilization chamber, the use of peroxygen
The dispersion of hydrogen gas and the plasma released during its plasma phase. Act on the cells, enzymes and nucleic acids of microorganisms, destroy their vitality and achieve the purpose of sterilization.
2. Features of low temperature plasma sterilization
①Hydrogen peroxide low-temperature plasma sterilization technology is highly effective. Its sterilant can penetrate some small cracks to kill the spores located in the lumen and holes.
②Hydrogen peroxide plasma low-temperature sterilization time is short, does not affect the waiting time of consecutive operations, improves the utilization rate and turnover rate of equipment, can reduce the purchase of valuable equipment, and reduce the hospital
cost.
3. The hydrogen peroxide low-temperature plasma sterilization does not pollute the environment. It only requires a working room and ordinary voltage, does not require steam water and special ventilation and drainage facilities, and is degraded into water and oxygen after sterilization. It is safer for patients, operators and the environment.
4. Use hydrogen peroxide plasma low-temperature sterilizer to sterilize the endoscope, and the loss of the endoscope is small, because its sterilization temperature is 45℃~50℃, it is gentle on the metal surface, and the instrument is not damaged, and it is after the terminal sterilization is out of the pot. Can be used immediately.
Killing microorganisms: it can kill bacteria and spores.
Main bactericidal factors and strength: 56%-63% hydrogen peroxide.
二. Treatment before sterilization
1. Sterilized items should be washed with water and dried thoroughly.
2. Sterilized items should be cleaned thoroughly and fully dried, then double-wrapped with non-woven fabric and sterilized.
3. Sterilized items should be placed in a single layer without overstocking, and there should be gaps between packages, and they should not be placed too tightly
dense.
4. The packed items should not exceed 80% of the volume of the container
5. During the sterilization process, pay attention to the fault prompt on the touch screen, and restart the machine after troubleshooting.
6. Do not open the door forcibly after the sterilization, wait for the buzzer to end, and then wait for the door.
7. The active ingredient in the disinfectant is hydrogen peroxide, which easily penetrates into the skin. When contacting the sterilant, be sure to wear latex gloves and handle the empty card holder correctly.
8. The content of hydrogen peroxide in the disinfectant used with the sterilizer is 56%-63%. Before using hydrogen peroxide, a concentration indicator card should be used.
9. Before sterilization, confirm that the hydrogen peroxide is within the validity period. The hydrogen peroxide cartridge that has expired should be removed and disposed of.
