The cover is removed in order to engage the chamber.

Abstract: A flexible collapsible container is filled with fluid by connecting a fluid conduit to a tubular port which communicates through one of the walls of the container to the container interior, and rupturing a sealing diaphragm that closes the bore of the tubular port. One then passes fluid through the conduit to fill the container. Thereafter, one seals either or both the tubular port and plastic wall which carries it to the other, opposed plastic wall of the container with seal line means to close off flow communication between the bore of the tubular port and a major portion of the container interior which contains the fluid. The effect of this is to block flow communication between the bore and the fluid so that the contents of the container remain sealed on disengagement of the fluid conduit from the tubular port.

Abstract: A device is described for accurately transferring multiple individual fluids from multiple source containers into a single receiving container. Fluid flows from the multiple source containers through individual fluid conduits to a chamber having a single fluid outlet conduit. The fluid outlet conduit is in fluid communication with a single receiving container. A pressure conduit is in communication with the chamber for alternately creating positive and negative pressures in the chamber to cause fluid to flow from the individual source containers into the chamber, and to cause fluid flow from the chamber into the receiving container in response to commands from a controller.

Abstract: An improved method of recovering antihemophilic factor (AHF) from cryoprecipitated blood plasma is provided. The improved method incorporates the addition of a calcium ion source during the step of cold precipitation of fibrinogen and fibronectin contaminants, as well as the addition of polyethylene glycol (PEG) at one of various stages of the recovery process. PEG may be added during the cold precipitation of fibrinogen and fibronectin, during the precipitation of AHF, or prior to the filtration of AHF solution. The method of the present invention results in a final AHF product having greatly increased solubility, higher specific activity, and lower fibrinogen and fibronectin content.

Abstract: Blood-compatible, chlorine-free polymers such as a flexible, non-toxic, sterilizable polyester plastic formulation may contain from 5 to 70 percent by weight of a blood-extractable ester such as di-2-ethylhexylphthalate, to cause blood which is stored in contact with the polymer to exhibit a surprisingly low hemolysis rate when compared with corresponding polymers which are free of the plasticizer. Accordingly, blood bags, tubing and other medical blood-contacting devices may be advantageously made from these polymers.

Abstract: A method of manufacturing a tear-off port protector for a container comprises placing flexible, typically extruded tubing on a mandrel that fills the bore of the tubing, with the tubing preferably outwardly stretched by the mandrel. A cutting blade is spaced a predetermined distance of less than the tubing wall thickness from the mandrel. One then causes the cutting blade to form an annular cut about the tubing, while maintaining the predetermined distance, and thereafter one removes the tubing from the mandrel.
