    Abstract: The present invention provides an intravenous fluid flow regulator 10 for controlling the I.V. administration of medical fluid to a patient. The fluid flow regulator 10 provides a housing 12 having a top 18 and a bottom 20. A flexible diaphragm 14 is positioned within housing 12. A diaphragm holder 16 is provided inside housing 12 for holding a sealing edge 56 of flexible diaphragm 14 in fluid sealing engagement with diaphragm holder 16. The housing 12 and flexible diaphragm 14 define an inlet fluid reservoir 62 and an outlet fluid reservoir 64. The diaphragm holder 16 defines a by-pass fluid channel 54 from inlet fluid reservoir 62, around diaphragm 14, to outlet fluid reservoir 64. The flexible diaphragm 14 being flexible to alternatively move into inlet fluid reservoir 62 and outlet fluid reservoir 64 depending on a fluid pressure differential between inlet fluid reservoir 62 and outlet fluid reservoir 64. A fluid inlet 24 is connected to housing top 18 to provide an inlet fluid passage 27 from an I.V. bag containing medical fluid to inlet fluid reservoir 62. A fluid outlet 34 is connected to housing bottom 20 to provide an outlet fluid passage 44 from outlet fluid reservoir 64 to the patient. At least one rib 48 connected to bottom 20 is provided to prevent movement of flexible diaphragm 14 into outlet fluid reservoir 64 when flexible diaphragm 14 moves into outlet fluid reservoir 64 a predetermined distance.

    Abstract: La presente invencion proporciona un regulador del flujo de fluidos para controlar la administracion I.V. de fluido medicinal a un paciente. El regulador del flujo de fluidos proporciona un alojamiento que tiene una parte superior y una parte inferior. Un diafragma flexible se encuentra colocado dentro del alojamiento. Un sujetador del diafragma se proporciona dentro del alojamiento para sujetar un borde de cierre hermético del diafragma flexible en un acoplamiento de cierre hermético a los fluidos con el sujetador del diafragma. El alojamiento y el diafragma flexible definen un deposito del fluido de entrada y un deposito del fluido de salida. El sujetador del diafragma define un canal del fluido de paso desde el deposito del fluido de entrada, alrededor del diafragma, hacia el deposito del fluido de salida. El diafragma flexible, es flexible para moverse de manera alternativa hacia el deposito del fluido de entrada y hacia el deposito del fluido de salida, dependiendo de una diferencia de presion del fluido entre el deposito del fluido de entrada y deposito del fluido de salida.

    Abstract: A system for the selective separation of a specific cel population from a heterogeneous cell mixture is disclosed herein. Means are provided for obtaining a selective cell concentrate from the heterogeneous cell mixture by separating the selective cell concentrate based upon the physical or biological properties of the concentrate. This may be done by centrifugation, if desired. A container is provided having particle means, the particle means being attached to a substance that is active for binding to a specific desired cell. One brings the cell concentrate into contact with the particle means within the container, for example, by providing sterile connection between the site where the cell concentrate is formed and the container. This permits incubation of the cell concentrate with the particle means, to thereby selectively bind a specific cell population from the cell concentrate to the particle means, creating a particle/cell conjugate. Magnetic means are then provided for separating the particle/cell conjugate from the remainder of the cell concentrate. A two-magnet system may be used to form the separation.

    Abstract: An adapter includes a base connectable to an anesthetic agent container, a spout that extends from the base and defines at least one flow path therethrough, and a valve assembly disposed within the at least one flow path, the valve assembly being moveable between a first open position and a second closed position. The adapter also includes a radially expandable seal disposed about the spout, the seal having a first end, a second end, and an intermediate region between the first and second ends that expands radially outward relative to a longitudinal axis of the spout. The valve assembly has a surface that cooperates with the seal, wherein the cooperation between the surface and the seal expands the intermediate region radially outward relative to the longitudinal axis with the valve assembly in the first position.
