  • Publication number: 20140326671
    Abstract: Disclosed are systems and methods for the performance of kidney replacement therapy having or using a dialyzer, control components, a sorbent cartridge with at least two separate flow paths, and fluid reservoirs configured to be of a weight and size suitable to be worn or carried by an individual requiring treatment. The system for performing kidney replacement therapy has a controlled compliance dialysis circuit, where a control pump controls the bi-directional movement of fluid across a dialysis membrane. The dialysis circuit and an extracorporeal circuit for circulating blood are in fluid communication through the dialysis membrane. The flux of fluid moving between the extracorporeal circuit and the dialysis circuit is modified by the rate at which the control pump is operating such that a rate of ultrafiltration and convective clearance can be controlled.

  • Publication number: 20140330193
    Abstract: An access disconnection system includes: an arterial line; a venous line; a transmitter configured to transmit a sound wave in one of the arterial and venous lines when connected to a patient; a receiver configured to receive the sound wave from the other of the arterial and venous lines when connected to the patient; and electronic circuitry coupled to at least one of the transmitter and receiver, the circuitry configured to send a disconnection output indicative of a change in the sound waves received by the receiver from the transmitter sufficient to expect that an access disconnection of one of the arterial line and venous lines has occurred.

  • Publication number: 20140088484
    Abstract: 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.
