Abstract:
1. A leak detector for a sterile contiguous fluid line for infusing a patient, the fluid line including a draw line connectable to at least one patient access and a return line directly connected to said at least one patient access, said detector comprising: a portion of the fluid line adapted to be interoperable with a pump actuator such that fluid may be conveyed therethrough; a filter, or filter connectors to permit connection to a filter, to complete a closed fluid circuit joining said draw and return lines; said pump actuator having a first configuration in which a positive pressure is generated in said return line and a second configuration in which a negative pressure in said return line, whereby a flow through said return line and said at least one patient access may be reversed when the pump actuator switches from the first configuration to the second configuration, and a blood leak sensor coupled to said fluid line, wherein the return line is connected to said at least one patient access and forms a continuous fluid passage substantially free of gases.
