Systems and methods for dissolving ozone gas in a liquid. An embodiment can comprise a tank having an upper region, a lower region, and a discharge outlet, all disposed in a specified geometry. A pump can be coupled with a liquid inlet in order to receive a liquid therefrom and to deliver the liquid via a pipe to the upper region of the tank. The pump can be coupled with the lower region of the tank in order to receive the liquid from the tank and to recirculate the liquid to the upper region of the tank. The apparatus can include an ozone inlet to receive ozone into the tank. The ozone inlet can comprise a venturi inlet disposed on the pipe downstream of the pump. The liquid can be released from the tank and depressurized, thereby providing for the ozone to emerge from the liquid as gas bubbles. The released liquid can be selected for a two-stage gas and aqueous cleaning process.

A patient warming system for stabilizing and/or heating and cooling a patient includes a plurality of solid-surface sections arranged for attachment to a surgical table and a warming pad layer comprising a plurality of warming pads configured for removable connection to the plurality of solid-surface sections. At least one of the plurality of solid-surface sections includes a power connector for connection to an external power source. Each warming pad of the plurality of warming pads includes a foam insulation layer, a distributed heating element layer having a warming-pad power connection for connection to the power connector, an isothermal layer, and a flexible waterproof layer. Power supplied to the warming-pad power connection of the distributed heating element layer of the respective warming pad can be used to provide a user-selected uniform temperature over the surface of the flexible waterproof layer in order to prevent hot spots.

A light source module including a fixing plate configured to extend in a first direction; a circuit board disposed on the fixing plate; a plurality of ultraviolet light emitting elements disposed on the circuit board in the first direction; a first reflection plate disposed at one side of the fixing plate; and a second reflection plate disposed at the other side of the fixing plate. Further, the plurality of ultraviolet light emitting elements are disposed between the first reflection plate and the second reflection plate in the first direction.

A medical device inspection system may include a base, a medical device holder on the base, a fiber scope holder on the base, a moveable roller moveably attached to the base such that it is free to rotate around an axis and move from a first position to a second position along the base, and a feeder coupled with the base for feeding a flexible portion of the fiber scope into a lumen of the medical device. During use, the flexible portion of the fiber scope may extend from the handle, around the moveable roller, and through the feeder to enter an opening in the lumen of the medical device.

The present invention relates to a device for applying medical and cosmetic radiation to a human body or to parts thereof. Said radiation is preferably optical radiation. The device according to the invention comprises at least one first illuminant for producing the medical and cosmetic radiation. The device also comprises a first air flow for cooling an illuminant and a second air flow for cooling the human body or parts thereof. The device comprises at least one air-conditioning system, which is fluidically connected to the second air flow and designed for the air-conditioning treatment of the air flow. The device is characterized in that the device also has at least one disinfecting chamber, which is fluidically connected to the second air flow and is designed to physically disinfect the second air flow. The invention also relates to a method for operating such a device and to a corresponding disinfecting chamber.

A UV disinfectant system may include a chamber having a wall that is transparent to a disinfecting radiation. Liquid may be flowed through the chamber for treatment by exposure to the radiation. The chamber may include a static mixer having vanes to impede laminar flow of the liquid during treatment. The vanes extend into the flow path of the liquid through the chamber. A gap is defined between the vanes and the transparent wall. A cabinet may house the chamber and radiation emitting bulbs. Blowers may be operably coupled to a temperature sensor and flow meter and positioned at a lower end and upper end of the cabinet to urge air out of the cabinet. The temperature sensor may include a thermocouple. The blowers may be variable speed blowers. The system may include a controller to control system operations. The controller may be remotely accessible to monitor or control operations.

An infrared heating system is disclosed that includes an enclosed tube extending from a first open end to a second open end, the enclosed tube having a sidewall opening in a sidewall of the tube at a location between the first and second open ends; an infrared heater mounted to the exterior of the enclosed tube such that heating elements of the infrared heater are exposed to the tube sidewall opening; and an auger disposed within the enclosed tube, the auger being driven by a drive system such that material fed into the enclosed tube at the first open end is transported to the second open end of the tube and is exposed to the heating elements of the infrared heater as the material is transported between the first and second open ends.

An illuminated bassinet including a light source for delivering therapeutic light and anti-bacterial light, where an interlock prevents the anti-bacterial light from being emitted while an infant is located in the bassinet. Also, a surgical illuminator configured to concurrently or alternately emit different wavelengths of light for treating a physiological condition and for affecting perception of the surgical opening.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell.

In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

Electrical connectors and fixtures, and more particularly, electrical plug and socket combinations allowing quick connection and mounting of electrical fixtures are provided with a disinfection feature for disinfecting air and/or surfaces. Additionally, lighting fixtures include or are retrofitted to provide both lighting and disinfection functions. The disinfection feature can be provided by any suitable source of UV radiation, such as an LED array. The emitted UV radiation is UV-A or FAR UV-C so that disinfection can occur regardless of whether a human is exposed to the emitted UV radiation or the emitted UV radiation is UV-C so that disinfection should only occur if there is no human exposure to the emitted UV radiation. Some electrical connectors and fixture can provide both types of emitted UV radiation, which are selectively actuatable.
