A system for separating and transferring phases of a fluid through centrifugation including a centrifuge having a rotating axis, a platform that is rotatable around the rotating axis; and a device for separating and transferring the phases of the fluid. The device includes a separating container and a receiving container connected to the separating container through a connecting channel. A passive valve system is provided in the connecting channel. The device is mounted in the centrifuge platform such that in use at a first predefined range of centrifugal force a fluid provided within the separating container is separated into phases and at a second predefined range of centrifugal force the valve system opens, thereby transferring a phase of the fluid from the separating container to the receiving container.

Methods and for treatment of cancer and other diseases including complications from late stage viral infections by inducing hyperthermia in a patient relying on withdrawing blood from the patient and returning the withdrawn blood to the patient to establish an extracorporeal flow circuit. Blood is heated by passing through the extracorporeal circuit at a controlled rate until a target body core temperature in is achieved. Usually, the blood will be subjected to a continuously re-circulating dialysis to balance electrolytes. Additionally, the blood will be subjected to a continuously recirculating regeneration through a carbon sorbent column where toxins and contaminants are removed. The blood temperature is maintained at the target blood temperature for a treatment period, and the blood is cooled after the treatment period has been completed. The method can also be effective in treating rheumatoid arthritis, scleroderma, hepatitis, sepsis, the Epstein-Barr virus, and patients with life threatening complications from other viruses, including the COVID-19 virus. A method for removing viruses from the blood supply in an external circuit is also presented.

A blood component collection system (10) includes a first internal pressure calculation unit (110) adapted to calculate a first internal pressure of a first pressed portion (60) using first calibration curve data (118), a second internal pressure calculation unit (112) adapted to calculate a second internal pressure of a second pressed portion (62) using second calibration curve data (120), and a correction unit (114) adapted to correct the first calibration curve data (118) in a manner so that the first internal pressure becomes equal to the second internal pressure in a state in which operation of a collection and returning pump (100) is stopped during at least one of a collection operation and a returning operation of a first cycle.

The invention relates to a system and method to sanitize a fluid while it is moving through a distribution system. The invention provides significant improvements in efficacy and reductions in cost over previous approaches. At least one embodiment of the invention is applicable to commercial, industrial, military, government, public and private facilities that employ forced-air ventilation systems, especially those with comparatively dense human occupancy. The invention has particular utility in hospitals, health care facilities, manufacturing facilities, offices, apartments and dormitories, military housing, afford and schools, as well as on ships, commercial airliners and in public and private transportation. At least one embodiment of the invention may be used to deliver UV-C to a specific surgical site to sanitize the site to prevent future infection.

The present invention discloses a microstructured discrimination device for separating hydrophobic-hydrophilic fluidic composites comprising particulate and/or fluids in a fluid flow. The discrimination is the result of surface energy gradients obtained by physically varying a textured surface and/or by varying surface chemical properties, both of which are spatially graded. Such surfaces discriminate and spatially separate particulate and/or fluids without external energy input. The device of the present invention comprises a platform having bifurcating microchannels arranged radially. The lumenal surfaces of the microchannels may have a surface energy gradient created by varying the periodicity of hierarchically arranged microstructures along a dimension. The surface energy gradient is varied in two regions. In one pre-bifurcation region the surface energy gradient generates a fluid flow. In the other post-bifurcation region, there is a difference in surface energy proximal to the bifurcation such that different flow fractions are divided into separate channels in response to different surface energy gradients in each of the post-bifurcation channels. Accordingly, fluids of different hydrophobicity and/or particulate of different hydrophobicity are driven into separate channels by a global minimization of the fluid system energy.

A system for wound treatment using a serum, comprising a device for recovering serum from whole blood, comprising: a blood bag for the reception and coagulation of whole blood, which has an outlet for discharging the serum-containing fluid from the blood bag and a barrier in the region of the outlet for retaining the coagulum, a filter module which is fluidically connected to the blood bag and comprises a housing and an interior, in which a semi-permeable membrane is arranged, said membrane dividing the interior into a retentate space and a permeate space and separating the fluid discharged from the blood bag into a permeate comprising the serum and into a retentate in which any particulate components contained in the fluid remain. The system for wound treatment further comprises a wound care system with a capillary membrane system for dispensing the serum to a wound. The capillary membrane system is connected to at least one supply line, which for its part is connected to the permeate outlet of the filter module.

A method of improving meibomian gland function in a patient includes inserting a cannula into an interior of a meibomian gland of the patient through an orifice thereinto, the cannula including at least one opening in communication with the interior of the meibomian gland, and injecting a blood product into the interior of the meibomian gland through the inserted cannula via the at least one opening.
