This invention serves to repurpose existing ethylene oxide sterilization chambers utilizing a novel chemical means of sterilization. Ethylene oxide is a longstanding gaseous sterilant for medical devices but has increasing problems associated with its hazards. Ethylene oxide is a carcinogenic and explosive chemical, and its emissions can be very harmful and cause serious health risks. Due to this, the FDA and many medical device manufacturers are trying to reduce or eliminate the use of the gas. Chlorine dioxide gas is a nearly identical alternative mode of sterilization that is non-carcinogenic and non-explosive. If firms choose to eliminate the use of ethylene oxide but do not want to waste the capital expenditure on existing sterilizers, they can instead utilize the ethylene oxide-to-chlorine dioxide conversion system of the present invention and use an effective and environmentally friendly form of sterilization in a system they already possess.

Provided is a hypochlorous acid disinfection water machine. The hypochlorous acid disinfection water machine includes a water inlet pipeline; a primary electrolyte cell, which is internally provided with a cation exchange membrane, and the outlet end of the water inlet pipeline communicates with the primary electrolyte cell; and a secondary electrolyte cell, which is a non-membrane electrolytic cell, a primary hypochlorous acid solution in an anode chamber of the primary electrolyte cell communicates with the secondary electrolyte cell, the primary hypochlorous acid solution in the anode chamber of the primary electrolyte cell is electrolyzed again in the secondary electrolyte cell to obtain a secondary hypochlorous acid solution. The hypochlorous acid disinfection water machine provided by the disclosure may solve the problem of poor concentration stability of a hypochlorous acid disinfection water machine in the relevant art.

An apparatus for sanitizing a fiberoptic endoscope includes an elongated box with an interior storage chamber and a cleaning piece connected to the exterior of the box. The cleaning piece and the box are arranged in-line with one another and are configured to receive a flexible endoscopic cable of a fiberoptic endoscope inside of them to sanitize and sterilize the cable. The flexible endoscopic cable is first inserted in the cleaning piece via a through opening of the cleaning piece. The cleaning piece includes a plurality of filtering media in its interior, each with a respective through hole. The flexible endoscopic cable is disinfected as it is moved through the filtering medium through holes. Having passed through the filtering media, the flexible endoscopic cable travels to the interior storage chamber of the box, where it is irradiated by an ultraviolet light source for sterilizing the flexible endoscopic cable.

A space purification device according to the present disclosure includes: electrolysis bath; water supply unit; electrode unit (140); first calculator (510) that calculates an increased concentration of hypochlorous acid water per unit time based on (i) a first sodium chloride concentration that is a sodium chloride concentration in the electrolysis bath after the sodium chloride concentration has changed due to an input of the electrolysis accelerator into the electrolysis bath and (ii) hypochlorous acid generation efficiency per unit time set in advance; second calculator (512) that calculates, based on a target hypochlorous acid water concentration in the electrolysis bath, a first hypochlorous acid water concentration that is a hypochlorous acid water concentration in the electrolysis bath before energization by electrode unit (140), and the increased concentration of hypochlorous acid water per unit time calculated by first calculator (510), a required energization time for achieving the target hypochlorous acid water concentration; and electrode controller (540) that performs energization in electrode unit (140) for the required energization time calculated by second calculator (512).

Disclosed are systems for providing safe, conveniently onsite, quick and effective ways to deliver antimicrobial and antiviral treatment to objects. Further disclosed is an isolation unit for sterilizing objects, the isolation having a lockable hatch that enables access, when unlocked, to a sterilization chamber within the isolation unit. The hatch remains locked until a sterilization operation is completed. Further, the hatch is prevented from being opened until the sterilization operation is completed. This feature prevents potentially harmful sterilizing chemicals from emitting out of the sterilization chamber, among other possible benefits.

A catheter storage and sterilisation device (99); the device comprising a catheter-receiving chamber (10) for receiving a catheter (1); a sterilisation fluid storage means (70) for storing a sterilisation fluid and an atomiser (53) or vaporiser configured to atomise or vaporise the sterilisation fluid to form an atomised or vaporised sterilisation fluid and to supply the atomised or vaporised sterilisation fluid to the catheter-receiving chamber (10).

The present invention is a portable, on-demand hypochlorous acid (HOCL) generator and sprayer device contained in a wireless electrostatic backpack system designed for the purpose of sanitizing and disinfecting. The system converts a feeder solution of water mixed with sodium chloride acetic acid into a hypochlorous acid solution at adjustable concentrations (25-400 ppm) by electrolysis using both anode and cathode electrodes. The resulting solution is pressurized to 50-130 psi, and then atomized into an ultra-fine mist (40-80 microns) that passes through an electrically charged annular element to positively charge the atomized droplets, increasing the transfer efficiency to negative and neutrally charged surfaces by providing a wraparound, attractive force on surfaces sprayed. Various sensors, controls and a central processing unit (logic controller) are used to ensure the consistency and accuracy of the required output. The hypochlorous acid produced through this on-demand system is non-toxic and environmentally friendly.

A system, comprising: a chlorine source in form of an electrolysis unit to generate an insitu generated active chlorine; wherein a concentration of perchlorate is not more than half of a concentration of chlorate; and pH of a fluid containing in-situ generated active chlorine is more than 7.4; a buffer tank to store a concentrate of in-situ generated active chlorine as a free available chlorine (FAC); a fluid distribution system to supply FAC in form of an in-use fluid to the cabinet; wherein the system is configured to clean and disinfect an article with the fluid while complying with national and international standards for food safety, operator's safety and regulatory requirements regarding the use of biocides.
