  • Patent number: 10806843
    Abstract: A method for operating a dialysis machine to conduct a dialysis treatment on a patient (e.g., a peritoneal dialysis machine) may include transferring dialysate from a first bag, and automatically determining the dialysate from the first bag has completely transferred. After determining the dialysate has completely transferred from the first bag, switching from the first bag to a second bag of dialysate. The method may further include transferring dialysate from the second bag in response to the detection of the completed transfer of the first bag, and automatically determining the dialysate from the second bag has completely transferred. The method may further include determining if the respective first or second bag has completely transferred by comparing a dialysate bag volume transferred to the patient to a detected volume of the respective first or second bag. Systems with dialysis machines for performing such a method are disclosed as well.

The present invention also relates to a method of balancing fresh and used dialysis fluid. The apparatus and method according to the present invention for balancing fresh and used dialysis fluid are characterized in that the individual balancing chambers of the balancing system receive both fresh dialysis fluid and used dialysis fluid, the functions of the balancing chambers being alternately interchanged. In this way, exact balancing can be achieved even when the volumes of the individual chambers differ from one another. Over the period of the treatment as a whole, the differences between the volumes balance each other out due to the cyclic interchange of the chambers.

    Abstract: A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.

  • Patent number: 9248225
    Abstract: A medical treatment system, such as a peritoneal dialysis system, may include a control and other features to enhance patient comfort and ease of use. For example, a cycler device may include a heater bag receiving section and a lid mounted to cover and uncover the heater bag receiving section, potentially enabling faster heating of a dialysate. A user interface may be moveable to be received into the receiving section and covered by the lid, if desired. The system may detect anomalous conditions, such as tilting of a housing of the system, and automatically recover without terminating a treatment. The system may include noise reduction features, such as porting pneumatic outputs to a common chamber, and others. The system may also automatically detect any one of several different solution lines connected to the system, and control operation accordingly, e.g., to mix solutions provided by two or more lines and form a needed dialysate solution.

  • Patent number: 9078971
    Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include a control system that can adjust the volume of fluid infused into the peritoneal cavity to prevent the intraperitoneal fluid volume from exceeding a pre-determined amount. The control system can adjust by adding one or more therapy cycles, allowing for fill volumes during each cycle to be reduced. The control system may continue to allow the fluid to drain from the peritoneal cavity as completely as possible before starting the next therapy cycle. The control system may also adjust the dwell time of fluid within the peritoneal cavity during therapy cycles in order to complete a therapy within a scheduled time period.

  • Patent number: 9078972
    Abstract: A catheter for use in continuous flow peritoneal dialysis comprising an inflow tube and outflow tube, both connected on one end to a dialysis machine. The inflow tube is divided into a plurality of inflow auxiliary tubes, and the outflow tube is divided into a plurality of outflow auxiliary tubes, with all auxiliary tubes encased in a single external tube. The auxiliary tubes each contain a plurality of apertures for the rapid and efficient movement of dialysis solution in and out of the peritoneal cavity to reach a larger surface area without kinking or blocking. The external tube comprises a tunnel for insertion of a fiber optic borescope to view the dialysis procedure. The auxiliary tubes are covered by a sheath prior to implantation, which is then removed, deploying, preferably into an open-basket shape, the auxiliary tubes within the peritoneal cavity to allow for the continuous flow of dialysis solution.
