Disclosed is a method for filtering a fibrinogen composition, comprising the following steps: a) purifying the fibrinogen composition by chromatographic purification using an elution buffer comprising arginine; b) optionally, at least one step of filtering the fibrinogen composition obtained by chromatographic elution in step a), on a filter having a pore size of between 0.08 μm and 0.22 μm, c) filtering the fibrinogen composition obtained by chromatographic elution in step a), or optionally obtained in step b), on a symmetrical filter having a pore size of between 15 nm and 25 nm, and preferably between 18 nm and 22 nm, and d) recovering the resulting fibrinogen solution, the filtering method being carried out without adding arginine after step a), at a high capacity and without a prior freezing and/or thawing step.

Certain exemplary embodiments of the present disclosure can provide an apparatus and method for generating at least one radiation can be provided. The exemplary apparatus and/or method can selectively kill and/or affect at least one virus. For example, a radiation source first arrangement can be provided which is configured to generate at least one radiation having one or more wavelengths provided in a range of about 200 nanometers (nm) to about 230 nm, and at least one second arrangement can be provided which is configured to prevent the at least one radiation from having any wavelength that is outside of the range can be provided or which can be substantially harmful to cells of the body.

An object of the invention is to provide a means for accomplishing inactivation of a pathogen in a blood sample containing red blood cells and platelets together, as well as sufficiently reducing the hemolysis rate of the red blood cell product finally obtained.

The means is to irradiate ultraviolet ray to a blood sample containing red blood cells and platelets in the presence of a hemolysis inhibitor and a surfactant having an HLB value of 13 or greater and having the number of oxyethylene groups of a hydrophilic portion in the molecular structure of 20 or greater when producing a blood product containing red blood cells and platelets.

A disinfection assembly for a person includes a chamber housing defining a floor area, an entry, an exit and an interior space between the entry and the exit. At least one of a UV light emitter or an atomization nozzle is positioned within the interior space. At least one platform is positioned and a sensor operatively coupled to the platform. A method for disinfecting a person in a disinfection assembly includes triggering at least one sensor in a disinfection chamber housing. The method includes at least one of emitting a UV light with a UV light emitter, or spraying a disinfection fluid from an atomization nozzle for a stipulated duration. The method includes stopping at least one of the emitting or the spraying after the stipulated duration. The method includes opening an exit door to permit a person to exit the disinfection chamber housing after the stipulated duration.

This invention relates to a method, process and apparatus for disinfecting and sterilizing all types of surfaces contaminated with microorganisms and toxic substances to render both inactive. Furthermore, this invention relates to both a method and apparatus for disinfecting and/or sterilizing breathable air and then using this air to protect a confined space from external contamination. The apparatus consists of a new ultra-violet (NUV) source that is more effective than mercury based 254 nm light for destroying DNA of virus, bacteria, spores and cists. It is most effective in breaking chemical bonds in toxic gases and Biotoxins that are useful to terrorists. It is combined with other apparatus that remove particulates and byproducts sometimes produced by the NUV source and maintains positive pressure of the confined space so as to prevent the influx of air from outside the protected zone.

A filter sterilization system includes an expiratory filter having filter material that collects pathogens present in the exhaled gas stream from a ventilated patient. A filter sterilizer includes an ultraviolet (UV) light source that is activated by the system to emit light towards the expiratory filter. Additionally, the system includes a ventilator coupled to a patient breathing circuit that provides a gas mixture from a gas source to the ventilated patient and transfers exhaled gases of the ventilated patient to the expiratory filter.

A germicidal system for use in disinfecting one or more contact surfaces includes one or more germicidal devices each comprising a germicidal light source. The one or more germicidal devices may be connected to a network, which allows for controlling the operational parameters of the one or more germicidal devices and/or collecting information from the one or more germicidal devices.

A sterilizing apparatus having both excellent safety and operability is provided. A sterilizing apparatus (1) according to an aspect for carrying out the present invention is a sterilizing apparatus (1) that radiates light including ultraviolet rays onto an affected area (6), wherein first wavelength light (L.sub.λ1) having a peak wavelength in a wavelength range of 190 nm or more and 230 nm or less, and second wavelength light (L.sub.λ2) having a peak wavelength in a wavelength range of 400 nm or more and 780 nm or less are emitted.
