VHP hydrogen peroxide low temperature plasma space sterilizer is mainly used in clinical medical equipment that meets the requirements of medical materials and geometric shapes. As long as it is used according to the requirements, the sterilizer can reach the sterilization level of 10-6SAL. The hydrogen peroxide low-temperature plasma sterilizer can perform low-temperature sterilization of metal medical devices and low-temperature sterilization of non-metal medical devices. Medical devices are sterilized by diffusing hydrogen peroxide within the chamber, which is then "energized" into a plasma state. Combined with plasma, hydrogen peroxide vapor can safely and rapidly sterilize medical instruments and materials without leaving toxic residues. All stages of the sterilization process are run in a dry, low temperature environment so they will not damage instruments sensitive to heat or moisture, work with both metallic and non-metallic instruments, and allow hard-to-reach items such as hemostat hinges (not easy to spread). ) to sterilize the parts of the instrument. The first company to introduce plasma sterilization technology was Johnson & Johnson of the United States. At present, domestic manufacturers such as Beijing Kesp, Chengdu Laoken, and Shandong Xinhua are well-known. Hydrogen peroxide plasma is a new low-temperature sterilization technology that was introduced in the 1990s. Plasma is considered to be the fourth state besides liquid, gas and solid. It is formed by the excitation of gas molecules in an extremely vacuum cavity. Hydrogen peroxide plasma sterilization has the advantages of short sterilization cycle time and complete decomposition of the final product with low toxicity. However, due to the contamination of Mycobacteria tuberculosis, the US FDA has not approved the use of a diffusion enhancer to solve the problem of the difficulty of hydrogen peroxide vapor penetrating long and narrow lumen items.
