  • Patent number: 11389575
    Abstract: A medical treatment machine, such as a home dialysis machine, can receive prescription parameters that define parameters of a medical treatment to be administered to a patient. A medical prescription is entered by a clinician into a clinical information system (CIS) that calls a system to evaluate the compatibility of the entered prescription by transmitting the prescription parameters to a server that has access to a database of medical devices and their operational parameters. The server compares the treatment parameters of the medical prescription to the operational parameters of the medical device and generates a prescription compatibility response indicting if the treatment parameters of the medical prescription can be executed by the medical device. The server returns to the CIS the prescription compatibility response to allow the prescription, e.g. in a digital or program form, to be securely transmitted or delivered via a connected health system to the medical device.

  • Patent number: 11389576
    Abstract: Embodiments of the disclosure provide a method for determining beginning blood volume of a patient during dialysis (e.g., hemodialysis). Ultrafiltration rates are determined at different time stamps during dialysis by obtaining a blood flowrate measurement and hematocrit measurements at input port and output port of a dialyzer connected to the patient. The flowrate and hematocrit measurements are used to determine fluid removed from the patient during dialysis. The ultrafiltration rates and fluid removed from the patient are used to determine the beginning blood volume of the patient.

  • Patent number: 11357896
    Abstract: Constraining adaptive optimizations of a state of an operation module of a medical device includes determining if a new state has at least one operational parameter that is outside a constraint that has been provided to the medical device in a non-repudiable manner, accepting the new state if no operational parameters are outside any of the constraints, and reverting the medical device to a previous valid state if at least one operational parameter is outside at least one of the constraints. The adaptive optimizations may be provided using artificial intelligence along with relevant inputs thereto. The medical device may be a dialysis system. Constraint data may be provided to the medical device along with a one-way hash value of the constraint data using, for example, a SHA 256 hash.

  • Patent number: 11331597
    Abstract: A sorbent cartridge device includes an ion-exchange material containing zirconium phosphate and no more than about 0.1 mg of leachable phosphate ions per about 1 g of the ion-exchange material. In one example, the cartridge also includes a phosphate-adsorbing material containing zirconium oxide. In this example, the weight ratio between zirconium phosphate and zirconium oxide in the cartridge is from about 10:1 to about 40:1. The zirconium phosphate may be alkaline zirconium phosphate prepared by a process including the following steps: (i) drying acid zirconium phosphate to obtain a dry acid zirconium phosphate; (ii) combining the dry acid zirconium phosphate with an aqueous solution to obtain an aqueous slurry; and (iii) combining the slurry with an alkali hydroxide to obtain the alkaline zirconium phosphate. During step (ii), any free phosphate ions in the dry acid zirconium phosphate leach out into the aqueous phase of the slurry.
