Abstract

Apparatus for monitoring fluid flow in dialysis systems include a tube holder for mounting the tube at a predetermined location on a dialysis monitor, a transmitter for transmitting a signal such as ultraviolet light through that location, a receiver for receiving the signal after it has passed through that location, and a sensor for sensing whether the tube is mounted at that location and whether the fluid is contained within the tube in response to the signal received by the receiver.
