In the medical field, the sterilization quality of surgical instruments is directly related to the patient's life safety and medical quality. According to the "Guidelines for Disinfection in Public Health Emergencies" released by the World Health Organization, approximately 10% of healthcare related infections worldwide are directly related to disinfection each year. How to ensure that every surgical instrument is in a sterile state has become a core issue in hospital infection control.
The sterilization of surgical instruments is a key link in hospital infection control, which directly affects the success rate of surgery, the speed of patient recovery, and the quality of hospital medical care.According to the risk level of medical devices, they are generally classified into three categories internationally: high-risk, medium risk, and low-risk devices. Among them, high-risk instruments such as surgical instruments, puncture needles, etc. must reach the sterilization level, which means killing all microorganisms, including bacterial spores.
Although traditional sterilization methods such as high-pressure steam sterilization are effective, they are not suitable for many precision instruments. Instruments with complex structures such as endoscopes and flexible endoscopes are not only expensive, but also highly sensitive to temperature and humidity, which requires efficient and low damage sterilization methods. Ethylene oxide sterilization is a traditional low-temperature sterilization method, suitable for electronic devices, plastic products, etc. that are not resistant to high temperature and humidity. It has strong penetration and will not damage the instruments, but this method has a long sterilization cycle, requires ventilation to remove residual gases, and poses a risk of toxicity, which is not friendly to the circulation of surgical instruments.
The low-temperature plasma sterilization technology using hydrogen peroxide has emerged to meet this demand,It utilizes the free radicals generated by hydrogen peroxide in a low-temperature plasma state to achieve rapid killing of microorganisms, and can achieve rapid and sterilization under low-temperature conditions.Due to its safety, efficiency, and applicability, hydrogen peroxide low-temperature plasma sterilization technology has gradually become a sterilization method for large comprehensive hospitals.
How to confirm whether the sterilization effect meets the standard during the low-temperature plasma sterilization process with hydrogen peroxide? Biological indicators are the "gold standard" for verifying their sterilization effectiveness.
The core of hydrogen peroxide low-temperature plasma sterilization biological indicator isChallenge the sterilization process with highly resistant microorganisms to achieve scientific validation of the effectiveness of the sterilization process.Its core components include thermophilic fatty Bacillus spores with certain resistance and a growth recovery medium.
The usage method is also relatively simple, that is, the biological indicator and surgical instruments are sterilized together. After sterilization, the biological indicator needs to be cultured under specific conditions. If the spores have been inactivated, the culture medium will maintain its initial purple color; If there are surviving spores, the acidic substances produced by their metabolism will cause the color of the culture medium to change to yellow. This color change presents the sterilization validation results intuitively through visual signals, providing clear judgment basis for medical staff.
The Tailin PS6-023 hydrogen peroxide low-temperature plasma sterilization biological indicator is suitable for identifying the sterilization effect of hydrogen peroxide low-temperature plasma sterilizers. After long-term development and comprehensive verification, the product meets the requirements of standards such as the Chinese Pharmacopoeia and GB/T 33417 "Method for Testing Biological Indicators for Hydrogen Peroxide Gas Sterilization", and is committed to solving the verification and monitoring problems of hydrogen peroxide plasma sterilizers. The product features are as follows:
Tailin Biological Indicator meets quality requirements such as ISO 11138, GB 18281, PDA TR51, and pharmacopoeias (USP, EP, Chp). The spores used can be traced back to the bacterial culture preservation center, and the inspection report includes spore concentration, D value, and other relevant data. Professional selection support services are also provided. Tailin Life Sciences will continue to be committed to microbial detection and control, providing you with high-quality solutions.
