    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.

    摘要翻译： 用于连续不卧床腹膜透析的设备，其中溶液容器通过柔性管连接到通过导管（通常是手术植入的导管）与患者的腹膜腔连通的患者管。 该设备包括具有转移口的柔性可折叠塑料透析溶液容器。 在其远端处具有鲁尔连接器的柔性管从传送端口延伸，用于连接到患者管所承载的鲁尔连接器。 柔性管带有易碎构件，其通常阻挡流体流动，但在易碎构件破裂之后允许流体流动。 微粒过滤器和可手动操作的夹具与柔性管串联。 腹膜透析是通过将鲁尔连接器从新鲜透析溶液袋连接到患者管路鲁尔连接器，破坏易碎构件，以及将柔性管上的夹子打开来实现的。 将透析溶液引入患者的腹膜腔内并保持在预定时间之后，将溶液排回到柔性袋中，将鲁尔连接器断开并重复上述步骤。 如果需要，一旦透析溶液已经被引入到患者的腹膜腔中，则路厄氏连接可能被断开并且患者的管路鲁尔连接器可能被封盖。

    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.

    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： A contamination protector for a medical device, principally for use in surrounding and protecting a connection between a plastic dialysis solution container (10) and tubing (22) carried by a patient practicing continuous ambulatory peritoneal dialysis. The protector is generally cylindrical in shape, and opens and closes much like a "clamshell." The inner wall surface (34) of the protector is adapted to carry a material (36) which holds a sterilizing agent in contact with a medical connection when the protector is in the closed position.
