A disinfection application, particularly, to a device capable of disinfecting a ventilator as well as a face mask and a hose, and more particularly, to an ozone disinfection device, an ozone disinfection system, and an ozone disinfection method. The ozone disinfection device includes: a sealed disinfection space, a gas distribution unit, an ozone generation unit, a suction pump, a filter, and a control module.

A method and apparatus for decontaminating substantially enclosed environments by using ultrasonic cavitation of a cleaning fluid to produce a low pressure, low air flow mist that can be activated by a nonthermal plasma actuator to create a cloud of activated hydroxyl species with the capacity to decontaminate articles, open surfaces or substantially enclosed spaces of pathogens, including bacteria, and other pathogenic microorganisms. An automated system and related non-transitory computer medium are also disclosed.

The invention describes a ceiling-mounted ozone-generating device (1) which comprises: at least one ozone-generating element (2); a fan (3) arranged in a position adjacent to the ozone-generating element (2) to propel the ozone generated by the ozone-generating element (2) outwards; a processing means (4) that controls the operation of the ozone-generating element (2) and the fan (3); and a housing which comprises a cover (5a) and a base (5b) that houses the ozone-generating element (2), the fan (3), and the processing means (4), wherein the housing comprises an air inlet hole (6) and an ozone outlet hole (7). Additionally, the casing comprises means for fixing it to the ceiling of a room.

The purpose of the present disclosure is to provide a method for producing pulp fibres for saccharification from the pulp fibres of used sanitary items, said pulp fibres for saccharification having low lignin contents distributed within a narrow range, and enabling the production of pulp fibres for saccharification having superior saccharification properties. The production method according to the present disclosure is characterised by comprising the following: a step for supplying a mixed solution (51) containing pulp fibres and highly-absorbent polymers sourced from used sanitary items to a treatment tank (31) via a mixed-solution supply port (32); a step for supplying an ozone-containing gas (53) to a treatment solution (52) within the treatment tank (31) via an ozone-containing-gas supply port (43); a step for lifting the ozone-containing gas (53) whilst lowering the pulp fibres and highly-absorbent polymers within the treatment tank (31), thereby bringing the ozone-containing gas (53) into contact with the pulp fibres and highly-absorbent polymers, and forming pulp fibres for saccharification from the pulp fibres; and a step for discharging the treatment solution (52) via a treatment-solution discharge port (33). The method is further characterised in that the pulp fibres for saccharification have lignin contents of 0.1% or less.

The present invention relates to an openable money-holding container (1; 100) for the disinfection of coins and/or tokens and/or banknotes and/or cheques and/or shopping vouchers and/or meal vouchers and/or paper and/or other securities (S; S′), comprising: a plurality of seats (13; 108) for holding coins and/or tokens and/or banknotes and/or cheques and/or shopping vouchers and/or meal vouchers and/or paper and/or other securities (S; S′); a fixed part (3; 101) and a mobile part (5; 105), wherein the plurality of seats (13; 108) is provided in the fixed part (3; 101) or mobile part (5; 105), the mobile part (5; 105) being movable with respect to the fixed part (3; 101) between a closing position, wherein the openable money-holding container (1; 100) is closed, and an opening position, wherein the openable money-holding container (1; 100) is open. The openable money-holding container (1; 100) further comprises at least one UVC ray emitter (7; 104), or at least one ozone lamp, connected to the fixed part (3; 101) or mobile part (5; 105) and arranged in a position such as to emit at least one beam towards the coins and/or tokens and/or banknotes and/or cheques and/or shopping vouchers and/or meal vouchers and/or paper securities and/or other securities (S; S′) when the mobile part (5; 105) is in said closing position. Such an openable money-holding container (1; 100) also comprises at least one air circulation device (15; 111) to circulate air inside the openable money container (1; 100).

The disclosure is based on a medical imaging apparatus with a scanner, a patient support apparatus and a housing, which is arranged on the scanner and/or on the patient support apparatus, wherein the housing comprises at least one functional housing shell, wherein the at least one functional housing shell comprises at least one sensor element for detection of a hygiene status on the at least one functional housing shell, at least one output element, which is embodied for a visual display of the hygiene status, and at least one cleaning element for cleaning a surface of the at least one functional housing shell.

A method of sterilizing an article such as a flexible endoscope is performed in a sterilization chamber. A vacuum is applied in the sterilization chamber while the article is contained in the sterilization chamber. A sterilant is then introduced into the sterilization chamber. The pressure within the sterilization chamber is incrementally increased to provide a step-wise transition from a high vacuum state to atmospheric pressure. The article is thereby sterilized.

A sterilization system uses ultraviolet radiation and ozone to eradicate deadly pathogens to sterilize a surface of an object or wound/incision site at an adjustable intensity level. The sterilization system has ultraviolet emitters that emit ultraviolet light in wavelengths that kill pathogens and in wavelengths that produce ozone at the sites, therefore killing/disabling several hard-to-kill pathogens. The sterilization system has an intensity control and proximity detectors to enable ultraviolet emission only when the system is properly located near or against the surface so as to protect from unwanted radiation from the ultraviolet light.
