    摘要： A solution pumping system includes a compressible pump cassette having front and rear body members, and an elastomeric diaphragm positioned therebetween. The front and rear body members are joined to each other for limited, relative movement, which movement effects compression of the diaphragm. The pump cassette is removably positionable in a pump driver of the system, which can be configured to effect compression of the cassette for use. In this way, the desired compression of the diaphragm during use can be achieved, while avoiding problems associated with compression set or load decay during storage of the cassette prior to use.

    摘要： A flexible container for medical solutions is provided that includes first and second film sheets sealed together along multiple sides so as to form a pouch having an open end. An end port member is located between and sealed to the first and second film sheets near the open end of the pouch to enclose the interior of the container. The end port member has at least one integrally-formed access port for fluid communication between the exterior and the interior of the flexible container. A portion of the first and second film sheets extend beyond the end port member and are sealed together along the edges of the extended portions so as to form a protective cover for the access ports. The protective cover is detachable.

    摘要： An apparatus and method are disclosed for compounding of parenteral admixture solutions, and recirculation with the admixture solution being formed. The apparatus includes a multiple pump cassette configured for operative association with a pump driver, whereby one or more selected source solutions are delivered through a pump cassette to an associated admixture container. After pumping of each source solution, the present method contemplates that the admixture being formed is recirculated through the pump cassettes thereby diluting any source solution in the cassettes and associated tubing. In this manner, the possible mixture of incompatible source solutions, resulting in formation of precipitate, is desirably avoided.

    摘要： A method and apparatus are provided for controlling the dispensing of a primary liquid from a pressurized source of primary liquid. Primary liquid is admitted through an inlet valve to a primary chamber having a primary element which is biased toward an initial position but is movable away from the initial position when subjected to the source pressure of the primary liquid. A sensor determines when the primary element has moved away from an initial position to a predetermined final position, and the inlet valve is closed in response thereto. The difference between the initial and final positions defines a predetermined dispensing volume. An outlet valve is opened to dispense the dispensing volume under the biasing force of the primary element which returns to the initial position. A sensor determines when the primary element has returned to the initial position, and the outlet valve is closed in response thereto.
