    摘要: A surgical suction system and method includes a source of suction and a conduit having a distal end and a proximal end. At its distal end, the conduit has a diameter not greater than about 5/8 inch to provide limited access to the surgical site and an inside diameter not less than about 1/4 inch to accommodate the bone fragments in the waste slurry. A coupling is provided for connecting the proximal end of the conduit to the suction source in order to provide suction at the distal end of the conduit at a velocity not less than about ninety miles per hour. A fluid containment vessel can be connected between the conduit and the source of suction to provide a liquid trap for the waste slurry passing along the conduit. An associated method includes the step of activating the suction source to provide suction at the distal end of the conduit with a velocity not less than ninety miles per hour.

    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。
