Abstract:
An electronic control unit for automatically interrupting the flow of irrigant to a urinary catheter, the control unit being connectable to a fluid sensor for automatically detecting an obstruction of a catheter, the control unit comprising:a) means for generating a control circuit being responsive to the fluid sensor, the control circuit being operable in at least two states, a first one of the at least two states indicating that there is no obstruction, and a second one of the at least two states indicating that there is an obstruction;b) means for selectively interrupting the flow of irrigant, said interrupting means being responsive to the control circuit so that when the control circuit is in the first state, said interrupting means allows irrigant to flow and so that when the control circuit is in the second state, said interrupting means blocks the flow of irrigant;c) said generating means including means for emitting a control signal and means for detecting the control signal; andd) said emitting means including a photon emitter, and said detecting means including a photon detector.
