  • Patent number: 9821105
    Abstract: Dialysis is enhanced by using nanoclay sorbents to better absorb body wastes in a flow-through system. The nanoclay sorbents, using montmorillonite, bentonite, and other clays, absorb significantly more ammonium, phosphate, and creatinine, and the like, than conventional sorbents. The montmorillonite, the bentonite, and the other clays may be used in wearable systems, such as a wearable peritoneal dialysis system, in which a dialysis fluid is circulated through a filter with the nanoclay sorbents. Waste products are absorbed by the montmorillonite, the bentonite, and the other clays and the dialysis fluid is recycled to a patient's peritoneum. Using an ion-exchange capability of the montmorillonite, the bentonite, and the other clays, waste ions in the dialysis fluid are replaced with desirable ions, such as calcium, magnesium, and bicarbonate.

  • Patent number: 9348975
    Abstract: Peritoneal dialysis therapy outcomes have been calculated for a variety of dwell times of peritoneal dialysis fluids in the peritoneal cavities of dialysis patients using kinetic modeling. The length of dwell time should not be the same for every patient, but should vary according to the patient condition and needs. Some patients have a potential for expressing greater ultrafiltrate into the dialysis fluid, and these patients can benefit from a longer dwell time, whereas other patients with less potential will not benefit from a longer dwell time. An optimal or peak time is observed for each peritoneal dialysis therapy outcome, such as ultrafiltrate volume rate, urea clearance (Kt/V), and creatinine clearance, while minimizing hydrocarbon absorption. These values and input parameters can be used to tailor the peritoneal dialysis dwell time for each patient, estimating the peak dwell time that will yield the best therapy outcome for each patient.

  • Patent number: 9132222
    Abstract: A system and method for automatically adjusting a Continuous Cycling Peritoneal Dialysis (“CCPD”) therapy to minimize the potential for excess intra-peritoneal volume. The adjustments are made at the end of the drain, just prior to the next fill. The adjustments short the next fill, if necessary, to limit the intra-peritoneal volume, add a cycle, if necessary, to use all of the available dialysis solution and will average the remaining dwell time to maximize the therapeutic benefit of the therapy in the allotted time. In another embodiment, a tidal therapy using trended patient UF data is provided.

  • Publication number: 20150231319
    Abstract: A medical fluid or dialysis system includes an auto-connection mechanism that connects connectors from the supply bags to dialysis cassette ports or cassette supply lines. The system provides for multiple, e.g., four, supply bags, which can be connected to a manifold of the auto-connection mechanism. Tip protecting caps that protect the supply line ends and cassette ports or cassette supply line ends are made to be compatible with the auto-connection mechanism. The auto-connection mechanism removes all the caps and connects the supply lines to the cassette. At least one roller occluder is provided that occludes the supply tubing prior to the tip protecting caps being removed. The roller occludes prevent medical dialysis fluid from spilling out of the supply lines between the time that the caps are removed and connection to the cassette is made.
