Description

Technical Field

[0001] The utility model relates to the technical field of sterilization and disinfection equipment, in particular to a novel plasma sterilizer. Background Art

[0002] The working principle of the low-temperature plasma sterilizer is to sterilize through hydrogen peroxide low-temperature plasma. During the disinfection process, a variety of microorganisms on medical devices and surgical instruments are inactivated in a specific way, thereby achieving the purpose of sterilization. It is mainly used for clinical medical equipment with materials and geometric shapes that meet the requirements. As long as it is used as required, the sterilization cabinet can consistently achieve a sterilization level of 10-6SAL. The hydrogen peroxide low-temperature plasma sterilizer can sterilize both metal and non-metal medical devices at low temperatures. The hydrogen peroxide diffuses in the chamber and then "stimulates" the hydrogen peroxide into a plasma state to sterilize the medical devices. Hydrogen peroxide vapor can safely and quickly sterilize medical devices and materials by combining with plasma without leaving any toxic residues. All stages of the sterilization process are operated in a dry and low-temperature environment, so it will not damage instruments that are sensitive to heat or water vapor. It is applicable to both metal and non-metal instruments, and can sterilize difficult-to-reach (not easy to diffuse) instrument parts such as the hinges of hemostat.

[0003] A low-temperature plasma sterilizer disclosed in the Chinese utility model patent application disclosure CN 213526552 U includes a box body and a sterilizer body, a first slide is fixedly connected to the lower side wall of the box body cavity, and telescopic rods are fixedly connected to the left and right sides of the upper side wall of the first slide, a support plate is fixedly connected to the top of the telescopic rod, a fixed plate is fixedly connected to the lower side wall of the support plate and located between the two telescopic rods, and movable rods are movably connected to the left and right sides of the lower side wall of the fixed plate through movable blocks. The utility model achieves a good shock absorption effect, avoids damage to the sterilizer body, reduces the maintenance rate of the sterilizer body, prolongs the service life of the sterilizer body, and greatly improves the working efficiency of the sterilizer body. The pulley and universal wheel facilitate the movement of the low-temperature plasma sterilizer, and the structure is reasonable, safe and reliable, and more solid and durable.

[0004] However, the device is not equipped with a vacuum mechanism, and is unable to completely extract the residual air in the sterilization chamber, causing harmful substances in the air to contaminate the instrument, thereby reducing the sterilization efficiency. The device is not equipped with a sterilization monitoring mechanism, and is unable to monitor the entire operation process, which is not convenient for ensuring the safety of the operator. The operation process is complicated and the operating cost is high. Utility Model Content
