A sterilization, disinfection, sanitization, or decontamination system having a chamber defining a region, and a generator for creating a free radical effluent with reactive oxygen, nitrogen, and other species and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The system is used in sterilizing, disinfecting, sanitizing, or decontaminating items in the chamber or room and, with a wound chamber, in treating wounds on a body. The wound chamber may be designed to maintain separation from wounds being treated. Various embodiments can control moisture to reduce or avoid unwanted condensation. Some embodiments can be incorporated into an appliance having a closed space, such as a washing machine. Some embodiments may include a residual coating device that deposits a bactericidal coating on sterilized items.

A plasma liquid generating device includes a tube, a plasma generating module, a flow limiting unit, and a position limiting member. The tube has at least an air inlet and a flow channel outlet. The plasma generating module is disposed adjacent to the air inlet and configured to generate plasma. The flow limiting unit is detachably disposed in the tube, and a distance between the flow limiting unit and the flow channel outlet is greater than a distance between the air inlet and the flow channel outlet. The position limiting member is detachably disposed at the flow channel outlet to limit the position of the flow limiting unit.

A decontamination system for a device, such as a lumen device, is provided. The decontamination system includes a terminal package defining a device receiving area. The terminal package includes a fluid inlet through which sterilant fluid can be delivered to the device receiving area. An accumulator apparatus is provided that is configured to switch between trapping sterilant fluid delivered into the device receiving area and delivering sterilant fluid to the device receiving area based on pressure changes in the device receiving area.

Disclosed is an escalator sterilization device attached close to a handrail of an escalator and formed by a base and a sterilization module. The sterilization module has a cover in an arc shape, so that the cover can be attached closed to a surface of a handrail of the escalator, and the inner wall of the cover has plural electrode coils electrically coupled to a power supply device in the base. After the power supply device is conducted by an electric power, a high voltage power is generated to excite the electrode coils to form plasma, and the plasma is used to destroy polymorphic bacteria and microorganisms, so that the sterilization module can eliminate the bacteria on the surface of the handrail of the escalator and provide a deodorant effect.
