Publication number: 20140088484Abstract: 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.Type: ApplicationFiled: December 4, 2013Publication date: March 27, 2014Applicants: Baxter International, Inc.Inventors: Rodolfo Roger, Robert Childers, Thomas D.
