Abstract:
A centrifugation system (10) includes a frame (12) having at least one weight supporting member (450) for engaging a support surface lying in a generally horizontal plane. The system also includes a centrifuge assembly (230), supported by a base (464) and including a chamber having an axis of rotation (344), which lies in a plane offset from a vertical plane orthogonal to the support surface. The sloped centrifuge conserves vertical height and makes possible for all components to be located in a zone between the user's chest and knees when standing.
Abstract:
A disposable set (20) for a blood processing device comprises an array of flexible tubing and a frame (72) that holds the flexible tubing array with at least two linear segments of the flexible tubing array presented for alignment with at least two axially aligned peristaltic pump rotors (112, 114, 116).
Abstract:
A method for creating a plastic component constructed, at least in part, from polychlorotrifluoroethylene, having improved properties, comprising the steps of: creating a compound from a composition that comprises polychlorotrifluoroethylene; heating the component to a temperature that is greater than the melting point of the composition; and rapidly quenching the component in a cold medium.
Abstract:
An adapter (100, 200) for interconnecting in fluid communication a first connection site (27) and a beneficial agent container having a closure. The adapter includes a plate having first and second connection site sides (104). A wall (110) extends from the plate (108) from the second connection site side and is constructed to surround only the closure. This allows containers having varying sized bodies to be received. A cannula structure (120, 130) is rigidly secured in the plate and defining a flow path extending through the plate. The adapter can be provided in assembly with the beneficial agent contained or in a drug delivery system.
Abstract:
Systems and methods for processing blood are disclosed. Blood is directed through the inlet (46) of a separation device (40) for removing undesired matter while directing the blood substantially free of undesired matter from the outlet (48) of the separation device (40) and into a collection container (18) through the first port (P1). Residual air from the collection container (18) is expelled through a second port (P2) different from the first port (P1). The residual air is directed toward the inlet (46) of the separation device (40) to remove residual blood from the separationdevice (40) for collection in the collection container (18) through the first port (P1).
Abstract:
An improved port protector (10) for removably sealing an opening located at an end of a tubular member. The port protector (10) comprises a cap portion (12) including a top (18) and side walls (17, 19) and defining an interior for receiving the end of the tubular member and removably sealing the opening of the tubular member. The cap portion (19) at least is constructed from a thermoplastic elastomer and the top (18) has a sufficiently thin cross-sectional thickness (a) to allow steam to pass through the top (18) into the opening of the tubular member during steam sterilization. Additionally, the port protector (10) includes means (14) extending from the cap portion (12) for allowing removal of the cap (12) from the tubular member. Additionnaly, the present invention provides an improved container assembly (30).
Abstract:
A method and device for stabilizing and storing bicarbonate solutions is provided. In an embodiment, a device (10) is provided having a container (11) and carbon-dioxide generating substances that include a solid material (13) which upon contact with water generates carbon-dioxide gas. The device may be packaged together with the bicarbonate or in a separate overpouch. The present invention also provides a method for the stabilization of bicarbonate solutions utilizing a means that generates high pressure carbon dioxide.
Abstract:
Systems for performing peritoneal dialysis allow the user to chose from an array of peritoneal dialysis modalities and adjust one or more individual therapy parameters within a selected modality. Still, the systems assure that the selected modality and therapy parameters satisfy preselected composite therapy criteria.
Abstract:
Viable microvessel endothelial cells are isolated from tissue in high yield by enzymatic digestion of tissue containing the cells using as a medium for the digestion, an enzyme composition in a physiologically acceptable aqueous electrolyte solution of pH 6.5 to pH 8.0 consisting essentially of sodium, potassium, magnesium, chloride, acetate, and gluconate ions, and having an osmolarity of about 270 mOsmol/L to 310 mOsmol/L. The electrolyte solution when mixed with a blood component is effective for stabilizing viable animal cells for periods of up to 4 hours.
