Abstract

The invention belongs to the technical field of sterilization of medical systems, and in particular, relates to a sterilization method and application of a hydrogen peroxide low-temperature plasma sterilizer. With adopting of technical schemes of purifying hydrogen peroxide by molecular sieve, regulating a concentration and control process, improving a control flow and determining reasonable parameters, articles are sterilized, the problem of limited use of a hydrogen peroxide low-temperature plasma sterilizer at present is solved, the application scope of the hydrogen peroxide low-temperature plasma sterilizer is greatly widened, and especially, the hydrogen peroxide low-temperature plasma sterilizer is suitable for disinfection and sterilization of objects with inner diameter of greater than or equal to 1 mm and the length of less than or equal to 500 mm.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of medical system sterilization, and in particular relates to a sterilization method and application of a hydrogen peroxide low-temperature plasma sterilizer. [0003] Background technique: [0004] Hydrogen peroxide low-temperature plasma sterilizer is a newly developed sterilizer in recent years, because of its low sterilization temperature, short sterilization time, no pollution after sterilization, and no harm to the operation and the user's body , is being recognized and accepted by the majority of users. [0005] However, as the number of times customers use it increases and their understanding deepens, more and more shortcomings are exposed in the sterilization process; because of its small sterilization pressure difference and weak penetration ability, it has a length limit for lumen sterilization. Especially for the most common endoscopic instruments for low-temperature sterilization in hosp...
