  • Patent number: 12070540
    Abstract: A detector assembly configured for use in a dialysis (e.g., a hemodialysis) system is disclosed herein. The detector assembly including a wetness detector configured to detect blood, fluid, a leak, etc. The detector assembly being operatively coupled to, and more preferably, including an inertial measurement unit (IMU). Thus arranged, the detector assembly is configured to measure, read, obtain, provide, etc. additional information or data during a dialysis treatment, which information or data can be transmitted and/or used to, for example, provide greater insight into the system and/or to make better decisions. In one embodiment, the detector assembly can be used to determine when and how a patient is moving and feed that information back to the dialysis machine. In use, the information or data can be used in combination with other information to make an improved determination as to the requirement for an alert and/or stoppage of the dialysis treatment.

  • Patent number: 11998674
    Abstract: A drip chamber is provided that includes a hollow body and a nucleation column extending into the interior of the hollow body or formed on the inner surface of a drip chamber sidewall. The nucleation column can be formed with, or treated by a treatment to include, microfeatures or other surface properties that provide nucleation sites for the nucleation and amalgamation of microbubbles. The drip chamber can include a bubble catcher in the bottom of the hollow body and the nucleation column can extend from the bubble catcher into the interior of the hollow body. Methods of making such drip chambers are also provided.

  • Patent number: 11971330
    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.
