Ternary compound sterilization method and sterilization device

Abstract

The invention provides a ternary complex sterilizing method and device, and belongs to the field of medical sterilization equipment. The ternary complex sterilizing method and device provided by the invention provides a vacuum pulse ozone sterilization manner, a hydrogen peroxide low-temperature plasma sterilization manner and a vacuum pulse vapor sterilization manner; and an operator can choose one or more manners for sterilizing according to an object to be sterilized. The ternary complex sterilizing device comprises a sterilization chamber (15), an ozone preparation and transmission pipeline, an emptying pipeline, a vacuum pipeline, an injection pipeline, a vapor pipeline and a drying pipeline, wherein the ozone preparation and transmission pipeline, the emptying pipeline, the vacuum pipeline, the injection pipeline, the vapor pipeline and the drying pipeline are mounted at the periphery of the sterilization chamber (15) in a connected manner. The ternary complex sterilizing method and device provided by the invention can provide the three different sterilization manners in work and use intelligent control in an entire sterilization process, and can be used by randomly selecting one or more manners in a combined manner, so that the ternary complex sterilizing method and device is specific and has wide application range in a sterilization process.

Description

technical field [0001] A ternary compound sterilization method and a sterilization device belong to the field of medical sterilization equipment, in particular to a sterilization and sterilization equipment used in the medical industry and a sterilization and sterilization method using the equipment, especially suitable for small-diameter, slender tubes Cavity for sterilization of medical devices. Background technique [0002] Medical sterilization equipment is an essential facility in modern hospitals and plays an important role in hospital infection control. The use of physical, chemical or biological methods to achieve safe, reliable, efficient and rapid sterilization research is an important topic in the field of disinfection. Currently, thermal sterilization is usually used for instruments that can withstand high temperatures, while low-temperature sterilization is used for instruments made of moisture and heat-sensitive materials. At present, the most important steri...

Problems solved by technology

However, ethylene oxide sterilization has safety and environmental problems: first, ethylene oxide has carcinogenic and allergenic effects, and there are residues on items after sterilization, which is harmful to operators and equipment users, and has an impact on the surrounding environment; Sterilization equipment needs to be installed with a special ventilation pipeline, and the items need to be degraded for more than 16h~48h after sterilization before they can be used

Some sterilization devices adopt the above multiple sterilization modes, but the sterilization process is single, and can only be completed sequentially from the beginning to the end according to the preset order, but some devices to be sterilized are not suitable for one of them Sterilization mode, which brings great inconvenience to the sterilization work
