INACTIVATION OF PATHOGENS IN EX VIVO BLOOD PRODUCTS IN STORAGE BAGS USING VISIBLE LIGHT

Disclosed herein are methods and devices for the inactivation of pathogens (e.g., bacteria, viruses, etc.) in ex vivo stored blood products, such as plasma and/or platelets, by means of directing visible light radiation from an illuminating device into blood product storage containers in order to achieve effective pathogen inactivation without the presence of an added photosensitising agent in the blood product. An exemplary apparatus includes a control unit that operates a light source that emits light in the wavelength region of about 380-500 nm which is directed onto blood product storage bags at sufficient intensity to penetrate the bag material and the opaque blood product therein in order to inactivate pathogens in the blood product but at dose levels that cause no significant detrimental effects on the blood product.

METHOD AND APPARATUS FOR STERILIZING AND DISINFECTING AIR AND SURFACES AND PROTECTING A ZONE FROM EXTERNAL MICROBIAL CONTAMINATION
20180353629 · 2018-12-13 ·

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 blood storage system comprising: a collection vessel for red blood cells; an oxygen or oxygen and carbon dioxide depletion device; a storage vessel for red blood cells; tubing connecting the collection vessel to the oxygen or oxygen and carbon dioxide depletion device and the oxygen or oxygen and carbon dioxide depletion device to the storage vessel; and a gamma or X-ray irradiating device is used to irradiate red blood cells stored in the vessel, storing red blood cells under anaerobic conditions.

Method for sterilizing blood purifier and blood purifier package

The invention provides a method for sterilizing a blood purifier, as well as a blood purifier package. The method is effective to decrease the amounts of extracts from the blood purifier attributed to the deterioration of the selectively permeable separation membranes with time during and after exposure to a radioactive ray or an electron ray, and is highly reliable in safety when employed for hemocatharsis therapy. The method for sterilizing a blood purifier which comprises substantially dried selectively permeable separation membranes as a main component, by way of the exposure of the same blood purifier to a radioactive ray and/or an electron ray, is characterized in that the blood purifier is sealed in a packaging bag, together with an oxygen scavenger and a humectant or together with an oxygen scavenger capable of releasing a moisture, and is then sterilized in such a sealed state by the above exposure.
