A patient line dislodgement detection device and method. An example device includes a body having an entrance and an exit. The entrance and the exit are each configured to receive a tubing line therethrough. Applying a force to a tubing line causes the body to restrict fluid flow through the tubing line, thereby indicating a dislodgement condition. An example method includes receiving a tubing line through a dislodgement device. The method also includes restricting fluid flow by the dislodgment device through the tubing line in response to application of a force on the tubing line. The method also includes detecting a dislodgment condition based on restricting the fluid flow through the tubing line.

An extracorporeal fluid treatment apparatus which is selectively operable in a disinfecting mode or a treatment mode includes an inlet line, a pre-treatment portion, an input pump, a heater, an input shunt, a filtration device, a post-treatment portion, a drain line and an output shunt. The apparatus also includes a combination of valves which are selectively positionable in disinfecting mode to create an input fluid circuit which includes the pre-treatment portion and the input shunt, and which is in fluid isolation from the post-treatment portion and from the filtration device. In disinfecting mode, the valves are also selectively positionable to create an output fluid circuit which includes the post-treatment portion and the output shunt, and which is in fluid isolation from the pre-treatment portion and from the filtration device. In disinfecting mode, a heated input fluid is circulated in the input fluid circuit and a heated output fluid is circulated in the output fluid circuit until disinfection of each of the input and output fluid circuits is achieved. The apparatus optionally includes a heat exchanger through which heat is transferred while in disinfecting mode from the input fluid in the pre-treatment portion to the output fluid in the post-treatment portion.

The amount of electrical power delivered to a dialysate heater in the dialysis machine is maximized without substantially exceeding a predetermined maximum allowed power consumption for the dialysis machine. The instantaneous power consumed by the machine is measured and compared to the maximum allowed power consumption. The excess of power beyond the instantaneous power consumed up to the maximum allowed power consumption is then made available to the heater. The worst case power consumption limitations of the dialysis machine components do not adversely affect the heat available from the heater. The rate at which dialysis treatments may progress may increase or the time required for dialysis treatments may decrease.

A method and apparatus for assisting in the detection of bubbles in a fluid stream such as an intravascular line. Tubing having ribbing or other texturing spaced along the longitudinal axis to enhance signal transmission characteristics and to increase the number of signals intercepted by a passing bubble, is placed between an ultrasonic or other transmitter and detector. In other embodiments, bubbles are concentrated into a detection zone by a centrifugator or are concentrated and recirculated in a detection zone by an eddy-producing protrusion in the fluid stream.
