  • Enhanced signal detection for access disconnection systems
    Patent number: 10155082
    Abstract: An access disconnection system includes an extracorporeal circuit; first and second contacts provided in the extracorporeal circuit; a current source communicating with the first contact and configured to generate a current within fluid flowing through the extracorporeal circuit; and an apparatus positioned to apply a signal at multiple points along a path from the extracorporeal circuit, the signals tending to prevent at least a portion of the current from traveling through a ground path in parallel to the extracorporeal circuit.

  • DIALYSIS FLUID MEASUREMENT METHOD AND APPARATUS USING CONDUCTIVE CONTACTS
    Publication number: 20090007642
    Abstract: A dialysate testing method in one embodiment includes placing electrical contacts in a dialysate flow path, measuring an electrical property of the dialysate as it flows through the flow path and past the contacts, and determining whether the dialysate has been mixed properly from the detected electrical property. A dialysate testing method in another embodiment includes flowing dialysate past a pair of electrical contacts, calculating a conductivity of the dialysate using an algorithm that takes into account a geometry of the contacts, and using the calculated conductivity to determine if the dialysate has been removed properly.
