摘要:
A system and methodology for the preservation of red blood cells is described in which red blood cells are oxygen or oxygen and carbon dioxide depleted, treated and are stored in an anaerobic environment to optimize preparation for transfusion. More particularly, a system and method for extended storage of red blood cells from collection to transfusion that optimizes red blood cells prior to transfusion is described.
摘要:
A portable assembly for processing red blood cells RBCs including a disposable blood collection set including a blood bag, an anaerobic storage bag and an oxygen and/or oxygen and carbon dioxide depletion device disposed between the blood collection bag and anaerobic storage bag. The portable assembly further provides for a gas circulation device in fluid communication with the oxygen or oxygen and carbon dioxide depletion device. The gas circulation device includes a pressure source that is able circulate flushing gas through the depletion device as RBCs pass from the blood collection bag, through the depletion device and into the anaerobic storage bag.
摘要:
An oxygen depletion device. The device has a cartridge; a plurality of hollow fibers extending within the cartridge from an entrance to an exit thereof; an amount of an oxygen scavenger packed within the cartridge and contiguous to and in between the plurality of hollow fibers. The hollow fibers are adapted to receiving and conveying red blood cells. There is another embodiment of an oxygen depletion device and method for removing oxygen from red blood cells.
摘要:
A system for reducing the concentration of oxygen in a fluid including red blood cells includes a housing, a plurality of hollow tubes extending within the housing and adapted for flow of the fluid therethrough, wherein each tube includes an inlet and an outlet, and a carrier system that reduces the concentration of oxygen at an exterior surface of the tubes to facilitate transport of oxygen from the fluid flowing through the tubes to an exterior of the tubes.

[Object] It is an object of the invention to provide a cleaning apparatus for cleaning a precision substrate capable of preventing a contamination factor from adhering again, to prevent a natural oxide film from being formed, and to prevent a water mark.[Solving Means] In a cleaning apparatus 1, a substrate-to-be-cleaned 2 is disposed in a container 3, and an atmosphere component measuring device 4 which measures an atmosphere in the container 3, gas supply means 5 for controlling an atmosphere, and gas discharge means 6 and 7 are disposed in the cleaning apparatus 1, the cleaning apparatus 1 includes at least one the gas supply means 5 which equally supplies gas from a portion opposed to a surface-to-be-cleaned, gas supply means 21 for supplying gas to a rotating/holding mechanism comprising a cylindrical stationary shaft 16, a fluid bearing 17 and a rotation support member 18, gas discharge means 7 for discharging gas into a drainage mechanism, and gas supply means 31 for supplying gas for controlling an atmosphere when cleaning liquid is injected. The atmosphere component measuring device 4 which measures the atmosphere in the cleaning apparatus 1 can measure at any timing, and can detect one or more of a flammable component, a combustible component and a oxdizer component.
摘要:
A plurality of liquid chemicals are fed onto a substrate to be treated, which is held and spinned, and the liquid chemicals scattered from the substrate to be treated by a rotator are separately recovered in respective recovery tanks (16 to 19) by each chemical. A lifting mechanism controls lifting operation of respective fences (3a to 3s) which form respective recovery tanks (16 to 19) so as to recover the liquid chemical into a certain recovery tank, while at the time, inlets of the other recovery tanks are closed at that time. Such a lifting mechanism includes a fence lifting plate provided with a cams portions 29a engaging with the respective fences (3a to 3d) to lift the corresponding fence, and performs lifting operation of the respective fences (3a to 3d) by rotating the fence lifting plate (29) around the shaft of the fence lifting plate (29) by a motor (34) so that the liquid chemical to be recovered is prevented from mixing in other recovery tanks.
摘要:
Method using oxygen removal for extending the useful shelf-life of refrigerated red blood cells. A cost-effective, 4.degree. C. storage procedure that preserves red cell quality and prolongs post-transfusion in vivo survival is described. Preservation of adenosine triphosphate levels and reduction in hemolysis and in membrane vesicle production of red blood cells stored at 4.degree. C. for prolonged periods of time is achieved by removing oxygen therefrom at the time of storage; in particular, by flushing with an inert gas. Adenosine triphosphate levels of the stored red blood cells are boosted in some samples by addition of ammonium phosphate.
摘要:
This invention relates to a vinyl chloride resin composition excellent in weather resistance and impact resistance. More particularly, the invention pertains to a weather resistant and impact resistant vinyl chloride resin composition low in cost and markedly improved in processability which comprises a vinyl chloride resin and a vinyl chloride graft copolymer prepared according to a specific process by graft-copolymerizing a vinyl chloride monomer on an ethylene-propylene-diene copolymer.
摘要:
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.
摘要:
A method of etching capable of rapidly and flatly performing wet etching on a Si substrate using fluonitric acid represented by HF(a)HNO3(b)H2O(c) (where the unit of a, b and c is wt % and a+b+c=100). The etching rate of an SiO2 layer with the highly concentrated fluonitric acid is significantly lowered by the appropriate selection of its composition as compared with the etching rate of the Si substrate, and etch the Si substrate until the SiO2 layer is exposed. In this way, it is possible to rapidly etch the Si substrate and significantly enhance the flatness of the etched surface.
