  • Patent number: 12220507
    Abstract: Dialysis systems are disclosed comprising new fluid flow circuits. Systems may include blood and dialysate flow paths, where the dialysate flow path includes balancing, mixing, and/or directing circuits. Dialysate preparation may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit fluid flow paths may be isolated from electrical components. A gas supply in fluid communication with the dialysate flow path and/or the dialyzer able to urge dialysate through the dialyzer and urge blood back to the patient may be included for certain emergency situations. Fluid handling devices, such as pumps, valves, and mixers that can be actuated using a control fluid may be included. Control fluid may be delivered by an external pump or other device, which may be detachable and/or generally rigid, optionally with a diaphragm dividing the device into first and second compartments.

  • Publication number: 20240127945
    Abstract: A method, related system and apparatus are disclosed. The method is implemented by an operative set of processor executable instructions configured for execution by a processor. The method includes the acts of: determining if a monitoring client is connected to a base through a physical connection; establishing a first communications link between the monitoring client and the base through the physical connection; updating, if necessary, the interface program on the monitoring client and the base through the first communications link; establishing a second communications link between the monitoring client and the base using the first communications link; and communicating data from the base to the monitoring client using the second communications link.

  • Patent number: 9517295
    Abstract: Dialysis systems are disclosed comprising new fluid flow circuits. Systems may include blood and dialysate flow paths, where the dialysate flow path includes balancing, mixing, and/or directing circuits. Dialysis systems may include a safety system utilizing a field programmable gate array (FPGA) that monitors at least conductivity and temperature of dialysate in the flow circuit upstream of a dialyzer and enters a fail-safe state if the measured conductivity is outside of a range of values. The FPGA may be verified to be operating properly by exposing sensors in fluid paths to temperatures or conductivities that are outside pre-determined permissible ranges of values, and confirming that the FPGA safety system enters a fail-safe state in response to the temperatures or conductivities. The FPGA may be configured to monitor an amount of ultrafiltration fluid withdrawn from a patient during dialysis treatment and to enter a fail-safe state if a maximum amount is exceeded.

  • Patent number: 5838336
    Abstract: The present invention provides an improved method and system for displaying images on a display screen. It includes a display screen, an on-screen memory, a cursor memory, and a display processor. The display processor in a normal mode displays on the display screen a graphics image stored in the on-screen memory. When the display processor is in an overlay mode, it simultaneously displays the stored graphics image, and the image stored in the cursor memory in an image window over a selected portion of the stored graphics image in the on-screen memory. The image window hides the selected portion of the stored graphics image. While the display processor is in the overlay mode, a second image is prepared and stored in the selected portion of the stored graphics image which is hidden by the image window.
