Abstract:
A blood sampling system including a sampling device located in line is provided. The sampling device (26, 70, and 102) provides an access port (40, 76, and 120) that allows undiluted blood to be sampled automatically by insertion of a luer. The sampling device can have a number of different structures, for example, a swing valve (41), a ball valve (88), or a breakable seal (130) for normally closing the sample port until a nozzle (60) of the luer blood collector is forcibly inserted into the sample port.
Abstract:
This invention is a container (46) for housing body fluids. The container comprises a body defined by flexible walls having an interior for housing the body fluid. An elongated tube (44) extends from the body for housing a fluid to be added to the body fluid. The tube includes means (18, 32) (see Fig.1) for allowing selective fluid flow from the interior of the tube to the interior of the body allowing the fluid to be added to the body fluid. Additionally, the means for allowing selective fluid flow allows the body fluid to be expressed from the body of the container into the elongated tube. The present invention also provides a method for storing and treating blood.
Abstract:
A method for separating blood into its components and individually storing same is provided. The method has the steps of: providing a container having a body with at least a first and second chamber. Selective fluid communication is also possible between the first and second chamber, and a tube is in fluid communication with the first chamber. The method also has the steps of: passing the blood into the first chamber through the tube; centrifuging the container to separate the blood into plasma, red blood cells and buffy coat within the first chamber; and expressing a portion of the centrifuged blood into the second chamber. In another embodiment, the method for storing blood has the steps of: providing a container with a body having three chambers. The method has steps that include passing the blood into a chamber through the tube; centrifuging the container to separate the blood into plasma, red blood cells and buffy coat and expressing a portion of the separated blood into second and third chambers from the collection chamber.
Abstract:
A steam sterilizable unit for inactivating pathogens in a body fluid is provided including a plastic structure for housing a therapeutically effective amount of a methylene blue solution. The plastic structure preferably includes at least an inner layer constructed from a non-PVC plastic. Preferably, the methylene blue solution has a pH of less than 7.0 and preferably less than or equal to approximately 6.3.
