  • Publication number: 20250078992
    Abstract: Systems and methods are provided to incorporate a high intelligence vertical efficiencies (HIVE) scheduler into connected health systems, which interacts with various entities in the connected health systems, and utilizes intelligent algorithms and an array of sensors to optimize clinic operations. The HIVE scheduler optimizes clinic operations by dynamically adapting schedules across various tasks within the connected health system. The HIVE scheduler determines adjustment to the schedules based on information such as alert/alarm events from machines, a variety of sensor data from within and outside clinics, and historical patterns. The systems and methods are applicable to both hemodialysis (HD) and peritoneal dialysis (PD) applications.

  • Publication number: 20250041495
    Abstract: A hydraulic system and method are provided for breaking-up, dislodging, removing, and preventing the build-up of biofilm in a dialysate pathway of an extracorporeal blood treatment device. The dialysate pathway can include a dialyzer discharge line, a drain line, a dialyzer feed line, and a bypass system. At least one ultrasonic device can be positioned and configured to generate ultrasonic waves in the dialysate pathway and to propagate the ultrasonic waves along at least a portion of the dialysate pathway. The ultrasonic waves can be used to break-up biofilm. An ionizing electrode pair can also, or instead, be implemented to break-up, dislodge, remove, and prevent a build-up of biofilm. The system and method can particularly be implemented and useful in non-disposable portions of a hydraulic system of an extracorporeal blood treatment device.

  • Publication number: 20240299637
    Abstract: Systems and methods are described for a dialysis machine (such as a hemodialysis machine) with proximity and motion sensors used to control simple functions of the dialysis machine through contactless interfacing that would otherwise normally be handled with glove changes. The sensors may be used to perform the same functions as using the touch screen display or the control panel of the dialysis machine. In an implementation, one or more of the sensors may be a proximity sensor that receives short-range wireless signals from a credential device of an operator, and one or more of the sensors may be a motion sensor enabling the operator to move a hand or foot near the sensor to enable contactless interfacing with the dialysis machine.

    Abstract: This disclosure relates to blood flow reversal valves and related systems and methods. In certain aspects of the invention, a blood flow reversal valve includes a first member having a first passage and a second passage, and a second member having a first passage and a second passage. The first and second members are rotatably fixed relative to one another such that the first passage of the first member is aligned with the first passage of the second member and the second passage of the first member is aligned with the second passage of the second member. A flow directing element is disposed in the cavity and is moveable relative to the first and second members between a first position in which the first passage of the first member and the first passage of the second member are fluidly connected and a second position in which the first passage of the first member and the second passage of the second member are fluidly connected.

  • Patent number: 11420037
    Abstract: A method of operating an extracorporeal blood treatment system to infuse blood into a patient at an end of an extracorporeal blood treatment includes clamping an access line of an arterial line set. The method further includes, after clamping the access line, initiating an operation to generate negative pressure in the arterial line set. The method further includes, after generating the negative pressure in the arterial line set, unclamping the access line to draw fluid in the access line further into the arterial line set in a direction away from an end of the access line that is connectable to an arterial access of the patient. The method further includes initiating an operation of a fluid pump engaged with the arterial line set such that the fluid in the arterial line set is infused into the patient through a venous line set.

  • Patent number: 10799117
    Abstract: The invention provides a health care delivery system comprising a plurality of health care delivery devices (e.g., via the Internet, etc.), which can disposed in treatment centers ranging from patient homes to commercial health care facilities such as hospitals, dialysis centers and so forth. Reporting functionality can, instead of or in addition to identifying (and reporting on) discrepancies in the raw and/or analyzed data from the delivery devices, infer (and report) on possible causes of those discrepancies and, in some aspects of the invention, remedy those causes, thereby, providing automated operations support for the treatment centers.
