Patent number: 11033671Abstract: A system for detecting whether a vascular access has been interrupted in an arrangement in which two catheters or needles are present in a blood vessel, fistula or graft. A fluid line leading to a pump is connected via a first connector to a first indwelling catheter, and a fluid line leading from a pump is connected via a second connector to a second indwelling catheter. Each connector is equipped with an electrode in contact with the lumen of the connector, the electrodes electrically connected to an electronic circuit that measures the impedance or conductivity of fluid between the first connector and second connectors via a fluid path through the blood vessel, fistula or graft. An electronic controller receives the impedance or conductivity data and processes the data to determine whether a vascular access disconnection has occurred.Type: GrantFiled: June 18, 2018Date of Patent: June 15, 2021Assignee: DEKA Products Limited PartnershipInventors: Dirk A. van der Merwe, Michael G. Norris, Michael A. Baker, Todd A. Ballantyne, Michael J. Wilt

Patent number: 9517295Abstract: 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 The FPGA may be configured to monitor an amount of ultrafiltration fluid withdrawn from a patient during dialysis treatment and to enter a fail-safe state if a maximum amount is exceeded.Type: GrantFiled: May 24, 2012Date of Patent: December 13, 2016Assignee: DEKA Products Limited PartnershipInventors: Michael J.
