Methods and systems for treating a biological fluid with light are disclosed. The methods and systems include determining the light dose being delivered to a biological fluid and adjusting the duration of a treatment or the intensity of light emitted in the event of a detected light source outage.

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.

A method and apparatus for reducing or inactivating pathogens in units of whole blood. A plurality of superparamagnetic nanoparticles (SPN) is coated with a mixture of chemiluminescence light-generating compounds and photodynamic broad-spectrum anti-viral compounds, and the mixture in introduced into a bag of whole blood. A rapidly-changing electromagnetic field is applied to the bag to cause uniform distribution of the nanoparticles within the whole blood throughout all regions of the blood bag, including the opaque interior of the bag. The blood is processed for a predetermined processing time period, during which the chemiluminescence light activates the broad-spectrum antiviral capacity of the photodynamic compounds to achieve reduction or inactivation of pathogens throughout the blood bag. After the processing time is elapsed, the nanoparticles are removed from the processed blood by a magnetic field. The processed blood may be washed by conventional means, to remove residual reagents, and transferred into a new, sterile blood bag.

An apparatus includes a fluid reservoir, a sterilization member, and a transfer adapter. The sterilization member operably couples to the fluid reservoir. The sterilization member is configured to be transitioned between a first configuration, in which the sterilization member obstructs an inlet surface of the fluid reservoir and maintains the inlet surface in a substantially sterile environment, and a second configuration, in which the inlet surface is unobstructed. The transfer adapter is configured to be placed in fluid communication with a portion of a patient. The transfer adapter is configured to move relative to the sterilization member from a first position to a second position such that a surface of the transfer adapter contacts the sterilization member to transition the sterilization member to the second configuration. The fluid reservoir is placed in fluid communication with the transfer adapter when the transfer adapter is in the second position.

The present invention relates to a blood bag system, a method for its manufacture, and a process for reducing pathogens and leucocytes in biological fluids in particular in therapeutic quantities of platelet concentrates (PC) contained in the blood bag system, using UV-light and agitation, wherein part of the plasma of the PC is optionally exchanged against a platelet additive solution.

A hemodialysis system including one or more ultraviolet chambers is disclosed. The hemodialysis system including a dialyzer arranged and configured to filter a patient's blood, a hemodialysis machine arranged and configured to pump, move, or the like dialysate through the dialyzer, the hemodialysis machine including an outlet valve and an outlet fluid flow path to pump or move dialysate from the hemodialysis machine to the dialyzer, and an inlet valve and an inlet fluid flow path to pump or receive dialysate from the dialyzer, and one or more ultraviolet chambers arranged and configured to kill bacteria, viruses, or a combination thereof. Thus arranged, by incorporating one or more ultraviolet chambers in strategic areas of the system, the ultraviolet chambers may eliminate, or at least greatly reduce, the possibility of cross-contamination in, for example, the dialysate, and thus eliminate the need for disinfecting the system between treatments.

A method and a system for producing a change in a medium. The method places in a vicinity of the medium at least one energy modulation agent. The method applies an initiation energy to the medium. The initiation energy interacts with the energy modulation agent to directly or indirectly produce the change in the medium. The system includes an initiation energy source configured to apply an initiation energy to the medium to activate the energy modulation agent.

Disclosed herein is systems, methods, and apparatuses for treating biological fluids. In some embodiments, the biological fluid treatment system includes a treatment, a platform, an array of light sources, and a display. In some embodiments, the biological fluid treatment system includes a scanner.

A system for generating light radiation to neutralize microorganisms comprises a light source for emitting a light radiation, storage means with one or more unique identification codes, each of which is associated with a respective microorganism, and at least one respective wavelength range associated with said microorganism, and a logic control unit. The logic control unit is configured to select a wavelength range based on the microorganism to be neutralized, activate the light source in such a way that light radiation emitted by said light source has a wavelength within said selected wavelength range, so that, when the system is in use, the light radiation induces optical resonance in the microorganism, causing denaturation of genetic patrimony of the microorganism.
