    摘要: A system and method for treating a fluid carrying a contaminant to which a photoactive material has been bound include a treatment device that defines a flow passage with a gap. The system and method operate to establish a flow of fluid from the inlet end of the gap to the outlet end of the gap. The system and method also channel the flow of fluid in the gap in succession through one or more flow paths. The system and method establish at least two discrete sources of radiation in the flow path at spaced apart locations along the direction of fluid flow. At least one of the radiation sources comprises a photodiode. The system and method further include a control for operating each discrete source of radiation at a selected wavelength within the prescribed range to activate the photoactive material bound to the contaminant. Upon activation, the material eradicates the contaminant. The system and method provide extracorporeal treatment of fluids like blood to quickly and effectively eradicate infection agents at relatively high flow rates.

    摘要: A contamination protector for a medical device, principally for use in surrounding and protecting a connection between a plastic dialysis solution container (10) and tubing (22) carried by a patient practicing continuous ambulatory peritoneal dialysis. The protector is generally cylindrical in shape, and opens and closes much like a "clamshell." The inner wall surface (34) of the protector is adapted to carry a material (36) which holds a sterilizing agent in contact with a medical connection when the protector is in the closed position.

    摘要: A method for treating a body fluid to at least substantially inactivate viral contaminants that may be present therein is provided. The method includes the steps of: providing a body fluid; adding to the body fluid a viral inactivating agent to create a resultant product; and passing the resultant product through a column including material having an affinity for the viral inactivating agent.

    摘要: A method and apparatus for inactivating viruses in a body fluid. A mixture including a therapeutically effective amount of methylene blue and an amount of a body fluid is formed in a container under sterile conditions and then the container is irradiated with a light field of a suitable intensity and wavelength for activating the methylene blue for a time sufficient to inactivate viruses in the mixture. The mixture is maintained in a substantially static state within the container.

    摘要: A blood reservoir comprises a rigid casing and a perforated tubular member positioned within the casing and extending between the edges thereof. An inlet aperture is at a position at the upper end of the reservoir in communication with the bore of the tubular member while an outlet aperture is positioned adjacent the bottom of the casing exterior to the tubular member. The bore of the tubular member contains first blood-defoaming means, and the tubular member carries a blood filter. In accordance with this invention, second blood defoaming means are positioned about the exterior of the tubular member to dissipate the fine bubbles without interference from the larger bubbles, which have been previously removed by passage through the first blood defoaming means.

    摘要: A diffusion system for blood including a membrane diffusion device comprising a plurality of blood flow paths positioned in interleaving diffusion exchange relation, with second fluid flow paths positioned on opposite sides of semi-permeable membrane means. The first and second flow paths each communicate with an inlet and an outlet. Heat exchange means having an inlet and an outlet is connected at the inlet thereof to the outlet of the first flow paths. A rigid reservoir, also having an inlet and an outlet is connected at its inlet to the outlet of the heat exchange means. A blood flow circuit is defined through the membrane diffusion device, heat exchange means, and reservoir. The flow circuit defines an essentially constant width, perpendicular to the directions of blood flow, from its beginning to end, to provide a system having good flow distribution in combination with a low pressure drop.
