A method of sterilizing material includes receiving the material in a sterilizing chamber, vaporizing sterilant supplied to vaporizer from a sterilant source, exposing the material to the vaporized sterilant by conducting a sterilization cycle in the sterilizing chamber, heating ambient filtered air supplied to the vaporizer from an ambient filtered air source, and removing residuals of the vaporized sterilant absorbed or adsorbed by the material during the sterilization cycle by conducting an aeration cycle in the sterilizing chamber. The removing of the residuals includes conducting a plurality of aeration pulses to provide the sterilizing chamber with an aeration atmosphere comprising the heated filtered air to vaporize the absorbed or adsorbed residuals, and conducting a plurality of aeration vacuum pulses to evacuate the aeration atmosphere and vaporized residuals from the sterilizing chamber.

Systems and methods for multiple band visible light disinfection are disclosed. In some examples, a disinfecting light is generated by combining two different disinfecting wavelength ranges of light. A lighting device may comprise a first light source that generates light in a Soret band. The lighting device may further comprise a second light source that generates light in a Q band. The light in the Soret band and the light in the Q band may be combined to generate disinfecting light.

The present invention provides a photosensitising composition comprising a mixture of: at least one surfactant; at least one alcohol; and/or water, with the proviso that when the at least one surfactant is an alcohol, it is different from the at least one alcohol. In particular, the composition may comprise a mixture of glycerol, ethanol and water. Alternatively, the composition may comprise a mixture of polyethylene glycol, ethanol and water. The photosensitising composition may further comprise at least one photosensitising compound. The present invention also provides a method of treating and/or preventing conditions caused by microorganisms in a subject.

A network-connected information and registration kiosk for use in waiting rooms of medical facilities such as Emergency Rooms configured to facilitate and expedite the check-in procedure, as well as the assist in a user's search for, and registration to, financial assistance programs. The kiosk presents an easy-to-use user interface which enables the user to locate and apply to assorted programs designed to assist in the payment for medical services, treatment, and procedures in accordance with his or her visit to the medical facility. The kiosk enables the user to get a jump-start on qualifying for such financial assistance programs immediately after the check-in process at the medical facility.

An organ preservation system having; an organ chamber with a perfusate reservoir, a pump arranged to circulate perfusate, from the reservoir and passes the perfusate through a dialysis filter, oxygenator, and temperature and pressure sensors prior to entering the chamber where an organ is perfused. The organ rests on the platform such that perfusate leaving the organ flows into the perfusate reservoir. The dialysis filter having permeable tubes which allow perfusate constituents to be exchanged with dialysate flowing through the dialysis filter. The dialysate pass through an ion exchange resin removing selected constituents or waste products from the dialysate by absorption by the ion exchange resin. Following waste absorption, the dialysate is recycled to the dialyzer to again remove waste. Removing waste products from the perfusate by dialysis followed by removal of the waste products from the dialysate with the exchange resin, enables dialysate reuse for extended duration.

The disclosure relates to a flexible active species generator comprising: a first electrode of a conductive metal thin film; a second electrode of a ground electrode; a flexible dielectric layer of an insulator formed between the first electrode and the second electrode; and a plasma resistant functional layer formed between the dielectric layer and the second electrode, wherein the first electrode and the second electrode are electrically connected to an external power supply to generate an atmospheric pressure plasma to generate active species. The flexible active species generator has a plasma resistant function to prevent deformation and decomposition of an insulator caused by the plasma as well as an active species generating function from atmospheric pressure plasma, and has durability and safety, which is thus applicable to articles, foods, garments and human body in various forms.

There is provided a system and method of cleaning surfaces of an enclosable environment of a contamination comprising a microbial and viral load. The method includes the steps of sealing the enclosable environment and placing water, and a solid or gel pack, into a container and generating a vortex the container by rotating an impeller. The agitation causes the solid or gel pack to release a gaseous cleaning agent. An air-borne spray exiting from the container spreads throughout the enclosable environment to contact the surfaces to be cleaned within the enclosable environment. The enclosable environment is maintained closed for an effective time period while the air-borne spray dwells on the surfaces to eliminate or substantially reduce the load of the contamination.

Gamma ray and e-beam irradiation provided efficient sterilization of certain self-assembling peptides (including RADA16 in solution) without substantial degradation of the major peptide, while, e.g., another self-assembly peptide, QLEL12 was significantly degraded following irradiation. Irradiation sterilization enhances the rheological property of, for example, RADA16 hydrogel once applied to tissue at a physiological pH. The rheological property increase can result in higher efficacy in a variety of biomedical applications.

A sanitizing booth includes integrally formed upper and lower body structures attached to one another to collectively define a compartment interior space. The lower body structure has side walls collectively defining an enclosed reservoir cavity for receiving a sanitizing solution therein. A first conduit extends from the ceiling of the upper body structure into the reservoir cavity. At least one second conduit extends downward from the ceiling along the interior surface of the compartment body. At least one sprayer is attached to the at least one second conduit for spraying the sanitizing solution. A pump arrangement in fluid communication with the first conduit and the at least one second conduit is configured to selectively and controllably draw the sanitizing solution from the reservoir cavity through the first conduit and pass it through the at least one second conduit and the at least one sprayer into the compartment interior space.

A method of sterilisation, certification and traceability of liquid nitrogen, includes the steps of preparing a container, provided with an opening, in use, at the top, and pouring into it a batch of liquid nitrogen to be sterilised; providing an identification element uniquely associable with the batch of liquid nitrogen, said identification element including an indicator of the sterilisation state of the batch contained in said container configured to modify its appearance following exposure to ultraviolet radiation; associating the identification element with the container of the batch of liquid nitrogen to be sterilised, positioning it in a portion of said container, adjacent to said opening; carry out a batch sterilisation treatment through exposure to ultraviolet radiation for a predetermined period of time, to modify at least one characteristic of the indicator to certify the sterilisation of the batch.
