  • Publication number: 20230293792
    Abstract: A dialysis system (e.g., a hemodialysis (HD) system) can be designed to operate in alternative environments, such as disaster relief settings or underdeveloped regions. The dialysis system can include a solar panel for generating electricity to power the dialysis machine and an atmospheric water generator for extracting water from ambient air. The extracted water can be used to generate dialysate and saline on-site. One or more of the components of the dialysis machine can be discrete components that are configured to facilitate fast shipping and simple on-site assembly (e.g., at a remote location). In some implementations, the discrete components may be configured to be attached to an existing dialysis system (e.g., a dialysis system designed for operation in a traditional environment) to permit the dialysis system to operate in an alternative environment.

  • Patent number: 11738125
    Abstract: Systems and methods for estimating the post-treatment ultrafiltration rate of a patient are provided. A medical device can be configured to determine an estimated post-treatment ultrafiltration rate based on one or more values associated with a patient prepared to undergo treatment with the medical device. The medical device can also be configured to compare the estimated post-treatment ultrafiltration rate with one or more threshold values. The medical device can be configured to have an alert module, which can be activated when the estimated post-treatment ultrafiltration rate exceeds the one or more threshold values.

  • Publication number: 20230160775
    Abstract: A leak detector is provided that is incorporated into the wheels of a moveable medical device and/or cart or cabinet therefor. By incorporating a leak detector into the wheels themselves of the movable medical device, the leak detector, despite movement of the medical device, is suitably located to locate leaks with respect to the medical device at all times and requires no additional setup. The leak detector can further be tested by and interface with the moveable medical device to ensure the leak detector is in working condition and provide a convenient interface for a user. Additionally, by using this technology on each of the multiple wheels of a moveable medical device, the detectable area may be bigger than a leak detector at only one location.
