    摘要: A system for metering nutrient media to cell culture containers includes a media flow conduit which defines at one end means for substantially aseptic communication with the source of the media. In a preferred embodiment, sterile connectors may be used for essentially sterile conditions. A branch conduit extends from the flow conduit at a location spaced from the ends. The branch conduit communicates with means for receiving a predetermined-volume aliquot of media through the media flow conduit from said one end. The flow conduit also defines a portion downstream from the branch conduit, which communicates with at least one cell culture container, each container being a flexible bag. At least part of the flexible bag is made of a material capable of providing at least 2 times the oxygen diffusion and at least 2 times the carbon dioxide diffusion between the bag interior and exterior, compared with an identically-sized, sealed bag having polyethylene walls 0.013 inch thick.

    摘要: Equipment for continuous ambulatory peritoneal dialysis in which a solution container is coupled via flexible tubing to a patient's tube that communicates with the patient's peritoneal cavity by means of a catheter, usually a surgically implanted catheter. The equipment includes a flexible, foldable plastic dialysis solution container having a transfer port. A flexible tube having a luer connector at its distal end extends from the transfer port, for connecting to a luer connector carried by the patient's tube. The flexible tube carries a frangible member which normally blocks fluid flow but permits fluid flow after the frangible member is broken. A particulate filter and a manually-operable clamp are in series with the flexible tube.Peritoneal dialysis is accomplished by connecting the luer connector from a fresh dialysis solution bag to the patient's tube luer connector, breaking the frangible member, and opening the clamp on the flexible tubing. After the dialysis solution is introduced into the patient's peritoneal cavity and remains there for a predetermined time, the solution is drained back into the flexible bag, the luer connectors are disconnected and the foregoing steps are repeated. If desired, once the dialysis solution has been introduced into the patient's peritoneal cavity, the luer connections may be disconnected and the patient's tube luer connector may be capped.

    摘要: A luer lock connection device for medical use, for example, in continuous ambulatory peritoneal dialysis in which a solution container is coupled via flexible tubing to a patient's tube that communicates with the patient's peritoneal cavity.The luer lock connection device includes a cooperating male luer lock connector and a female luer lock connector, with visual indicating means provided to indicate that the male and female connectors are assembled properly for use when they are in a predetermined relationship. The male and female luer lock connectors are structured to provide a double sealing arrangement for aiding in maintaining an uncontaminated connection.

    摘要: A gripper member comprises an openable and closable pair of handles interconnected by a hinge member. Each handle defines, adjacent its hinge member, an arcuate recess positioned to face the corresponding recess of the other handle and defining gripping projections therein. A wall member is positioned longitudinally on each handle to cross each arcuate recess, both wall members being positioned at the same side of their respective recesses. Accordingly, a plastic tube may be surrounded and gripped in the arcuate recesses of the handles for rotational retention thereof as a connector member is inserted into or withdrawn from the tube. At the same time, the wall members pinch the tube into closed, sealed relation with the handles in closed position.
