  • Patent number: 10350340
    Abstract: The invention relates to a method for separating blood, to a separation container and to a system, wherein different blood fractions—erythrocytes (64), buffy coat (65) and blood plasma (66)—are obtained, wherein blood is introduced into a separation container (1) and is then centrifuged into different superimposed, fluidically connected sections of the separation container, specifically a top section (4) for receiving the blood plasma (66), a middle section (3) for receiving the buffy coat, and a bottom section (2) for receiving the erythrocytes (64). The aim of the invention is to optimize the extraction of buffy coat. Said aim is achieved by means of the method and the separation container, wherein the optimization is geared to obtaining a defined phase boundary, and by means of the system, wherein the optimization is geared to achieving freedom from contamination from the time the blood enters the separation container and obtaining an easy-to-handle freezer container for cryopreservation.

  • Patent number: 8485727
    Abstract: A multiple chamber container for separately storing components of a parenteral nutritional formulation is provided. The multiple chamber container may include frangible barriers, preferably peelable seals separating the chambers from each other. The container preferably facilitates the selective activation of the peelable seals to permit the admixing of less than all the separately stored components. The container may include a chamber positioned at each of the opposite lateral ends of the container and at least one additional chamber between the lateral chambers. The at least one additional chamber may have a longitudinal length substantially less than the longitudinal length of at least one of the lateral chambers. This configuration allows for selective opening of the seals since when rolling the container from the top avoids pressurizing the at least one additional chamber and inadvertent activation of a seal.

  • Patent number: 8469938
    Abstract: The present invention relates to a process of fusion-bonding a plastic film (8a, 8b) to an object to be fusion-bonded such as a port member (16) in manufacturing a drug bag, and relates to a drug bag. The present fusion-bonding process comprises steps of disposing a heat generation element generating heat by absorbing infrared laser, on an opposite surface (8c) of the plastic film (8a, 8b) from the port member (16), or between the port member (16) and the plastic film (8a, 8b), pressing a press member (30a, 30b), which allows infrared laser to be transmitted therethrough, from a side of the plastic film (8a, 8b), and irradiating the infrared laser (L) to the heat generation element (24a, 24b) through the press member (30a, 30b).

  • Patent number: 8449520
    Abstract: A flexible container receives a liquid material, which is freeze-dried in situ within the flexible container. A gas permeable material that is separate from the flexible container provides gas transport for sublimation during drying and lyophilization. The gas permeable portion of the system can be isolated and removed from the flexible container post-lyophilzation The freeze-dried material is stored in the flexible container until administration is necessary. The flexible container receives a reconstituting liquid for mixing with the freeze-dried material, and conveys the reconstituted freeze-dried material from the flexible container for administration to an individual.
