摘要： An access disconnection system includes a blood treatment machine including a housing, an access site detection housing separate from the blood treatment machine housing, a transmitter positioned in the access site housing and configured to transmit an ultrasound wave into a blood stream of a patient, a receiver positioned in the access site housing and configured to receive a reflection of the ultrasound wave from the blood stream of the patient; and electronic circuitry in communication with the transmitter and the receiver. The electronic circuitry is supported by the access site detection housing, and the transmitter is configured to send a wireless disconnection output to the blood treatment machine. The disconnection output is indicative of a change in the reflected ultrasound wave received by the receiver sufficient to expect that an access disconnection of one of the arterial line and the venous line has occurred.

摘要： Methods are disclosed for providing certain operational instructions to a hemodialysis machine. The hemodialysis machine possesses a programmable memory and a capability of operating according to a time-varying parameter such as variable ultrafiltration. According to the methods, the machine operator enters into the memory a desired time period, a target cumulative value of the time-varying parameter, such as target UF volume, and a proposed time-varying profile of the time-varying parameter that is representable as a plot of coordinates in a region defined by an ordinate of values of the parameter and a time-based abscissa, wherein the plot defines a profile cumulative value of the parameter. If the profile cumulative value is not equal to the target cumulative value, then the proposed time-varying profile is changed along the ordinate so that the profile cumulative value is made equal to the target cumulative value. The machine then operates according to the changed profile to enable the apparatus to achieve, while operating, the entered target cumulative value within the time period.
