    Patent number: 8868350
    Abstract: A method of predicting serum phosphorus concentrations in a patient during hemodialysis includes measuring serum phosphorus concentrations of the patient over a hemodialysis treatment session time and an ultrafiltration rate calculated by a difference between pre- and post-dialytic body weight of the patient during an initial hemodialysis treatment session divided by a total treatment time of the treatment session and estimating a phosphorous mobilization clearance and a pre-dialysis distribution volume of phosphorus for the patient. Serum phosphorus concentrations of the patient can then be predicted at any time during any hemodialysis treatment session with the estimated phosphorous mobilization clearance and pre-dialysis distribution volume of phosphorus of the patient.

  • Transfer sets for therapy optimization
    Patent number: 8636706
    Abstract: Transfer sets are disclosed in the present patent. The transfer set provides a connection between a source of peritoneal dialysis fluid and a patient for whom peritoneal dialysis has been prescribed. The transfer sets disclosed herein are smaller and provide a more compact and convenient device by which a dialysis patient controls the flow of dialysis fluid to and from the peritoneum of the patient. The devices are more compact and convenient because they include more convenient mechanisms for starting and stopping flow of the dialysis fluid. It is also easy to determine whether the mechanism is in a closed or open configuration by simply looking at the mechanism.

  • System and Method for Providing Data Link Layer and Network Layer Mobility Using Leveled Security Keys
    Publication number: 20130305332
    Abstract: The present disclosure discloses a network device and/or method for providing data link layer (L2) and network layer (L3) mobility using level security keys. A first network device acting as a first level security key holder in a first network receives a first level security key holder identifier corresponding to a second network device in a second network. The first level security key holder identifier is originated from a client that roams from the second network to the first network. Moreover, the first network and the second network belong to a single roaming domain. Also, the network device transmits the first level security key holder identifier to the second network device and requests for corresponding first level security key. The network device then derives a second level security key and transmits a second level security key identifier the second level key holder in the first network.
