  • Patent number: 12642897
    Abstract: A control system operates (201) an apparatus for extracorporeal blood processing to extract, process and return the blood of an individual while removing fluid from the blood in accordance with a set value for ultrafiltration rate, UFR. The control system further obtains (202) sensor data representing one or more physiological parameters of the individual, and intermittently performs an optimization procedure (203) to generate the set value based on the sensor data. The optimization procedure comprises: evaluating (203A) the sensor data for detection of a limiting physiological status, LPS, sequentially controlling (203B) the apparatus in accordance with a test sequence of UFRs until the LPS is detected for a current UFR, and updating (203C) the set value based on the current UFR for use in operating the apparatus subsequent to the optimization procedure. The control system may perform a series of temporally separated optimization procedures during a treatment session to adapt the UFR to the individual.

  • Patent number: 12594369
    Abstract: A dialysis system and dialysis machine or cycler are provided that decrease a disposable set's cost and complexity. The dialysis machine or cycler includes a weigh scale on which multiple fluid supply containers containing dialysis fluid, and a drain trolley, are positioned. The fluid supply containers may be elevated relative to the drain trolley. The drain trolley is sized to contain all of the effluent drained from a patient during a dialysis treatment. The fluid supply containers are in fluid communication with one another and arranged one of top of the other. A control unit may control fill, dwell and drain cycles by controlling the operation of a pump and a valve. Dialysis fluid from the bottom-most fluid supply container may be pumped into a patient. The valve may be opened to allow effluent to drain from the patient to the drain trolley by way of gravity.

  • Patent number: 12548646
    Abstract: A medical device system includes renal failure therapy machines each including a memory. The renal failure therapy machines are communicatively coupled such that the memories collectively form a distributed database. The system also includes a logic implementer associated with each renal failure therapy machine. Each logic implementer is programmed to automatically access the distributed database, so that each renal failure therapy machine periodically delivers prescription input parameters and/or treatment output data to at least one of the other renal failure therapy machines, and retrieves prescription input parameters and/or treatment output data from at least one of the other renal failure therapy machines. One of the renal failure therapy machines is configured to create at least one treatment record trend from the treatment output data and to share the at least one treatment record trend with other renal failure therapy machines through the distributed database.

  • Patent number: 12180592
    Abstract: A device to ensure planarity of a semiconductor wafer during growth at an increased temperature in a growth chamber arranged in a reactor housing where the device includes a growth chamber having a port to allow the deposition of at least one wafer on a rotating susceptor in the growth chamber and the withdrawal of the wafer. The growth chamber has an inlet channel for a supply of process gases and an outlet channel for a discharge of not consumed process gases to create a process gas flow between said channels. Separate heaters are adjacent to the growth chamber to heat the rotating wafer with individually controlled heating zones both above and under the wafer. An instrument measures the bending of the wafer, and an automatic control circuit uses data from temperature sensors or measured data of power supplied to the heaters and the instrument measuring bending of the wafer to change the temperature in said temperature zones so that bending of the wafer is minimized.
